5 Things: Choosing New Running Sneaks

FitSugar — Thu, 23 Aug 2007 14:30:00 -0700

Finding the right sneaker is kind of like finding a good boyfriend. Running shoes should be comfortable, practical, and not too flashy. Here are some tips on finding the right shoe for you.

Figure out what type of foot you have (narrow, wide, low arches, no arches, etc.) and choose a sneaker to fit your foot. Don't look at color, brand, style, or price to gauge quality or superiority. You should base your decision on how they feel (chances are you'll find a few to choose from, not just the $175 pair). Also remember not to skimp on new sneakers either. There's a reason crappy sneakers are so cheap.
Think about where you'll be running and check out the material the shoe is made with. Many shoes are made with this airy mesh material so your feet don't overheat, but if you are going to be running near water, you'll want a waterproof sneak instead. Also, you may like the look of trail runners, but if you are strictly a pavement girl, you'll need a shoe that offers more cushion and support, and not such a rubbery sole.
Wear your old running shoes to the store. You'll probably be buying them at an athletic shop that's staffed with fellow runners, so have them look at your old kicks so they can gain some insight into what type of shoe may suit you best. Also wear the socks you'll be running in when trying on new sneakers.

Pick out shoes at the end of the day. Your feet are slightly larger then, since we spend so much time on our feet. If you pick out shoes at the end of the day, you'll ensure a more comfortable fit. It's better that they feel slightly loose than way too tight.
Break them in. Just because your new sneakers feel great in the store after wearing them for 5 minutes, doesn't mean they'll feel great after a 5 mile run. If the store has a treadmill or track you can run on, take them up on their offer. If they still feel good after a test run, buy them, and go on some shorter runs before zooming right into a 10k race.

Running: Treat Your Feet Right With Quality Sneakers

FitSugar — Thu, 09 Aug 2007 10:15:00 -0700

One of the reasons I love running is that it really requires no special gear. You just need a body and a desire to run. Then again, you might not need a racquet or clubs to go for a good jog, but I would suggest quality running shoes.

If you are taking up running, good quality running shoes can seriously make this habit stick. Old shoes, tennis shoes, cheap shoes often don't provide enough cushion to protect your feet, ankles, and knees which can lead to injuries and prevent you from learning to love running. Since shoes are really the only important gear needed for running, I wouldn't skimp on them. You don't need to pay out the nose for some newfangled shoe, but generally what you pay for is what you get. Expect to pay around $100. Which may sound like a lot, but can you really put a price on your knees? Plus, maybe the guilt of an expensive gear purchase will motivate you to run.

Look for a well cushioned shoe that fits your foot, matches your foot type and gait pattern. The best place to start this endeavor is a running store since they tend to employ people obsessed with running. Therefore they should be able to help you figure out your gait and point you toward the shoe for you. The American Council on Exercise recommends shoes with greater shock absorption for runners with high arches, which may make you more prone to ankle sprains. On the other hand (or foot I could say), if you have low arches look for a shoe with greater support and heel control. Here is a list of running shoes rated by the The American Academy of Podiatric Sports Medicine. It should help you figure out what brands could be good for your needs.

Fit's Tip: Buy a shoe that’s as wide as possible across the forefoot without slipping in the heel.

Highlights

Treatment for Ingrown Toenail:

Orthonyxia, a surgical technique that implants a small metal brace into the top of the nail, was as effective as traditional surgical techniques for preventing ingrown toenail from recurring, according to one study.
A nonsurgical method for treating ingrown toenail with chemicals uses either sodium hydroxide or phenol, but one study shows that sodium hydroxide procedures have a better outcome and faster recovery than phenol procedures.

Treatment for Forefoot Pain:

Ultrasound-guided injection of alcohol might provide relief from Morton's neuroma, according to one study. Symptoms improved in 94% of patients who had the treatment, a success rate comparable to that of surgery.

Treatment for Heel Pain:

NSAIDs reduce pain and disability in people with plantar fasciitis when used with other techniques, such as night splints and stretching.
Studies show that extracorporeal shockwave therapy provides a very small reduction in heel pain without side effects. It may be a good option for patients who haven't responded well to conservative treatment.

Work-related Foot Problems:

An estimated 120,000 job-related foot injuries occur every year, about a third of them involving the toes. A number of foot problems -- including arthritis of the foot and ankle, toe deformities, pinched nerves between the toes, plantar fasciitis, adult-acquired flat foot, and tarsal tunnel syndrome -- have been attributed to repetitive use at work.

Introduction

Foot pain is very common. About 75% of people in the United States have foot pain at some time in their lives. Most foot pain is caused by shoes that do not fit properly or that force the feet into unnatural shapes (such as pointed-toe, high-heeled shoes).

The foot is a complex structure of 26 bones and 33 joints, layered with an intertwining web of more than 120 muscles, ligaments, and nerves. It serves the following functions:

Supports weight
Acts as a shock absorber
Serves as a lever to propel the leg forward
Helps maintain balance by adjusting the body to uneven surfaces

Because the feet are very small compared with the rest of the body, the impact of each step exerts tremendous force upon them. This force is about 50% greater than the person's body weight. During a typical day, people spend about 4 hours on their feet and take 8,000 - 10,000 steps. This means that the feet support a combined force equivalent to several hundred tons every day.

Foot pain generally starts in one of three places: the toes, the forefoot, and the hindfoot.

The Toes. Toe problems most often occur because of the pressure imposed by ill-fitting shoes.

The Forefoot. The forefoot is the front of the foot. Pain originating here usually involves one of the following bone groups:

The metatarsal bones (five long bones that extend from the front of the arch to the bones in the toe)
The sesamoid bones (two small bones embedded at the top of the first metatarsal bone, which connects to the big toe)

The Hindfoot. The hindfoot is the back of the foot. Pain originating here can extend from the heel, across the sole (known as the plantar surface), to the ball of the foot (the metatarsophalangeal joint).

Condition	Location	Symptoms	Recommended Footwear
Toe Pain
Corns and calluses	Around toes, usually little toe, bottom of feet or areas exposed to friction.	Hard, dead, yellowish skin.	Wide (box-toed) shoes; soft cushions under heel or ball of foot, or customized or gel insoles for calluses. Doughnut-shaped pads for corns.
Ingrown toenails	Toenails.	Nail curling into skin causes pain, swelling, and, in extreme cases, infection.	Sandals, open-toed shoes.
Bunions and bunionettes (tailor's bunion)	Big toe (bunions) or little toe (bunionettes).	The following can occur alone or in combination: Metatarsus primus varus. The first (big toe) metatarsal bone shifts away from the second, and the big toe points inward. Medial exostosis. This is a bony bump at the base of the big toe, which protrudes outward. Area next to bony bump is red, tender, and occasionally filled with fluid. Toe joint may be inflamed. Hallux valgus. This is a deformity in which the bone and joint of the big toe shift and grow inward, so that the second toe crosses over the big toe.	Soft, wide-toed shoes or sandals. Bunion shields or splints. Thick doughnut-shaped moleskin pads, custom-made orthotics or foot slings, if necessary. Avoid shoes with stitching along the side of the "bump."
Morton's neuroma (also called interdigital neuroma)	Inflammation of the nerve, usually between the third and fourth toes and bottom of the foot near these toes.	Cramping and burning pain, or electric-shock sensation. The condition may produce a thick protective sheath around the nerve that feels like a ball. This may be detected by pressing top to bottom on the top of the foot using one hand and moving the other hand from side to side. Morton's neuroma is aggravated by prolonged standing and relieved by removal of the shoes and forefoot massage.	Wide (box-toed) shoes. Orthotic or insole with pad that reduces stress on the painful area.
Hammertoe or claw toe	Usually second toe, but may develop in any or all of the three middle toes.	Toes form hammer or claw shape. In hammertoe, the first knuckle of the toe is mainly affected. In claw toe the entire toe is deformed. No pain at first, but pain increases as tendon becomes tighter and toes stiffen.	Wide (box-toed) shoes. Toe pads or specially designed shields, splints, caps, or slings. (Splints or slings are not for people with diabetes.)
Front-of-the-Foot Pain
Metatarsalgia	Ball of the foot.	Acute, recurrent, or chronic pain without a known cause.	Wide (box-toed) shoes. Orthotic with pad that reduces metatarsal pressure. Gel cushions. Metatarsal bandage.
Stress fracture	Most often in the area beneath the second or third toe.	Sudden pain (which persists) when injury occurs.	Low-heeled shoes with stiff soles.
Sesamoiditis	Ball of foot beneath big toe.	Pain and swelling.	Low-heeled shoe with stiff sole and soft padding inside.
Heel and Back-of-the-Foot Pain
Plantar fasciitis or heel spurs	Back of the arch right in front of heel.	At onset, some people report a tearing or popping sound. Pain is most severe with first steps after getting out of bed. Pain decreases after stretching, returns after inactivity.	Over-the-counter foot insole (cut quarter-size hole surrounding painful area). Possible night splints. Orthotics if necessary.
Bursitis of the heel	Center of the heel.	Pain, with warmth and swelling. Increases during the day.	Heel cup.
Haglund's deformity (pump bump)	Fleshy area on the back of the heel.	Tender swelling aggravated by shoes with stiff backs.	Soft shoes. Heel pads. Possible orthotic to support heel.
Achilles tendinitis	Achilles tendon: area along the back between calf muscles and heel.	Pain worsens during physical activities (particularly running), after which the tendon usually swells and stiffens. If it ruptures, popping sound may occur followed by acute pain similar to a blow at the back of the leg.	Insoles, tendon strap, heel cups.
Arch and Bottom-of-the Foot Pain
Tarsal tunnel syndrome	Anywhere along the bottom of the foot.	Numbness, tingling, or burning sensations, pain, most commonly felt at night.	Specially designed orthotics to relieve pressure.
Flat feet or posterior tibial tendon dysfunction (PTTD)	The arch.	No arch. Often no pain or discomfort. Three stages in PTTD: Pain and weakness in the tendon. The arch flattens but is still flexible. The foot becomes rigid and possibly painful at the ankle. Sometimes people report fatigue, pain, or stiffness in the feet, legs, and lower back.	For children, possible custom-made insoles.
High arches (hollow feet)	The arch.	High arches. Lower back pain, possible tendency to lower limb injuries.

Causes

Nearly all causes of foot pain can be grouped under one of the following:

Ill-fitting shoes. Poorly fitting shoes are a frequent cause of foot pain. High-heeled shoes concentrate pressure on the toes and can aggravate, if not cause, problems with the toes.
Certain medical conditions. Any medical condition that causes a disturbance in the way a person walks can contribute to foot pain. This may include diseases or conditions that lead to pain or numbness in the feet (such as diabetes), leg and foot deformities, spinal problems, and neurological disorders such as Parkinson's disease or cerebral palsy.
High-impact exercise. High-impact exercising, such as jogging or strenuous aerobics, can injure the feet. Common injuries include corns, calluses, blisters, muscle cramps, acute knee and ankle injuries, plantar fasciitis, and metatarsalgia.

Arthritic Conditions. Arthritic conditions, particularly osteoarthritis and gout, can cause foot pain. Although rheumatoid arthritis almost always develops in the hand, the ball of the foot can also be affected.

Diabetes. Diabetes is an important cause of serious foot disorders. [For more information, see In-Depth Report #9: Diabetes - type 1 and In-Depth Report #60: Diabetes - type 2.]

Obesity. Obesity can cause foot and ankle pain.

Pregnancy. Pregnancy can cause fluid buildup and swollen feet. The increased weight and imbalance of pregnancy contributes to foot stress.

Medications. Some medications, such as calcitonin and drugs used for high blood pressure, can cause foot swelling.

Risk Factors

A risk factor is anything that increases your chances of getting a disease or condition. The following are factors that increase your risk for foot pain:

Elderly people are at very high risk for foot problems. As you age, your feet widen and flatten, and the fat padding on the sole of the foot wears down. The skin on the feet also becomes dryer. Foot pain in older adults may be the first sign of age-related conditions, such as arthritis, diabetes, and circulatory disease. Foot problems can also impair balance and function in this age group.

Taking fashion to extreme limits, some people have turned to cosmetic surgery as a drastic way to fit into high-heeled shoes. Procedures include surgical shortening of the toes, narrowing of feet, or injecting silicone into the pads of the feet. Such methods may increase your risk for future foot pain. The American Orthopaedic Foot and Ankle Society (AOFAS) and other foot-related medical associations have expressed concern over this trend. The AOFAS strongly advises against cosmetic foot surgery and urges consumers to carefully consider the relative risks and benefits of undergoing unnecessary surgical procedures.

Women are at higher risk than men for severe foot pain, probably because of high-heeled shoes. Severe foot pain appears to be a major cause of general disability in older women.

An estimated 120,000 job-related foot injuries occur every year, about a third of them involving the toes. A number of foot problems -- including arthritis of the foot and ankle, toe deformities, pinched nerves between the toes, plantar fasciitis, adult-acquired flat foot, and tarsal tunnel syndrome -- have been attributed to repetitive use at work.

For example, in a study of New York police officers who walked an average of 3 miles a day, 20% experienced foot pain at the end of their workday. (Insoles can relieve much of this pain.) No studies, however, have scientifically distinguished between injuries due to work versus those due to regular use. This is an important issue because of its potential impact on disability claims.

Pregnant women have an increased risk of foot problems due to weight gain, swelling in their feet and ankles, and the release of certain hormones that cause ligaments to relax. These hormones help when bearing the child, but they can weaken the feet.

People who engage in regular high-impact aerobic exercise are at risk for plantar fasciitis, heel spurs, sesamoiditis, shin splints, Achilles tendon, and stress fractures. Women are at higher risk for stress fractures than are men.

Gaining weight puts added stress on the feet and can lead to foot or ankle injuries. The added pressure on the soft tissues and joints of the foot in overweight people increases the likelihood of developing tendinitis and plantar fasciitis.

Treatment: Corns and Calluses

A corn is a protective layer of dead skin cells that forms due to repeated friction. It is cone-shaped and has a knobby core that points inward. This core can put pressure on a nerve and cause sharp pain. Corns can develop on the top of, or between, toes. If a corn develops between the toes, it may be kept pliable by the moisture from perspiration and is therefore called a soft corn.

Corns develop as a result of friction from the toes rubbing together or against the shoe. They often occur from the following:

Shoes, socks, or stockings that fit too tightly around the toes
Pressure on the toes from high-heeled shoes
Shoes that are too loose, due to the friction of the foot sliding within the shoe
Deformed and crooked toes

Calluses are composed of the same material as corns. Calluses, however, develop on the ball or heel of the foot. The skin on the sole of the foot is ordinarily about 40 times thicker than the skin anywhere else on the body, but a callus can even be twice as thick. A protective callus layer naturally develops to guard against excessive pressure and chafing as people get older and the padding of fat on the bottom of the foot thins out. If calluses get too big or too hard, they may pull and tear the underlying skin.

Risk factors for calluses include the following:

Poorly fitting shoes
Walking regularly on hard surfaces
Flat feet

Of note, in people with diabetes, the presence of calluses is a strong predictor of ulceration, particularly in those who have a history of foot ulcers.

Preventing Corns and Calluses and Relieving Discomfort. To prevent corns and calluses and relieve discomfort if they develop:

Do not wear shoes that are too tight or too loose. Wear well-padded shoes with open toes or a deep toe box (the part of the shoe that surrounds the toes). If necessary, have a cobbler stretch the shoes in the area where the corn or callus is located.
Wear thick socks to absorb pressure, but do not wear tight socks or stockings.
Apply petroleum jelly or lanolin hand cream to corns or calluses to soften them.
Use doughnut-shaped pads that fit over a corn and decrease pressure and friction. They are available at most drug stores.
Place cotton, lamb's wool, or mole skin between the toes to cushion any corns in these areas.

Removing Corns and Calluses. To remove a corn or callus, soak it in very warm water for 5 minutes or more to soften the hardened tissue, then gently sand it with a pumice stone. Several treatments may be necessary. Do not trim corns or calluses with a razor blade or other sharp tool. Unsterile cutting tools can cause infection, and it is easy to slip and cut too deep, causing excessive bleeding or injury to the toe or foot.

Medicated Solutions and Pads. There are numerous over-the-counter pads, plasters, and medications for removing corns and calluses. These treatments commonly contain salicylic acid, which may cause irritation, burns, or infections that are more serious than the corn or callus. Use caution with these medications. The following people should not use them:

Patients with diabetes
Patients with reduced feeling in the feet due to circulation problems or neurological damage
Patients who do not have the flexibility or eyesight to use them properly

Treatment: Bunions

A bunion is a deformity that usually occurs at the head of one of the five long bones (the metatarsal bones) that extend from the arch of the foot and connect to the toes. A bunion typically develops in the following way:

Most often it occurs in the first metatarsal bone (the one that attaches to the big toe). A bunion may also develop in the bone that joins the little toe to the foot (the fifth metatarsal bone), in which case it is known as either a bunionette or a tailor's bunion.
A bunion begins to form when the big or little toe is forced in toward the rest of the toes, causing the head of the metatarsal bone to jut out and rub against the side of the shoe.
The underlying tissue becomes inflamed, and a painful bump forms.
As this bony growth develops, the bunion is formed as the big toe is forced to grow at an increasing angle toward the rest of the toes. One important bunion deformity, hallux valgus, causes the bone and joint of the big toe to shift and grow inward, so that the second toe crosses over it.

Several conditions can cause bunions:

Narrow high-heeled shoes with pointed toes can put enormous pressure on the front of the foot.
Injury in the joint may cause a bunion to develop over time.
Genetics play a role in 10 - 15% of all bunions.

Flat feet, gout, arthritis, and occupations (such as ballet) that place undue stress on the feet can also increase the risk for bunions.

Shoes and Protective Pads. Pressure and pain from bunions and bunionettes can be relieved by wearing appropriate shoes, such as the following:

Soft, wide, low-heeled leather shoes that lace up
Athletic shoes with soft toe boxes
Open shoes or sandals with straps that don't touch the irritated area

A thick doughnut-shaped, moleskin pad can protect the protrusion. In some cases, an orthotic can help redistribute weight and take pressure off the bunion. Nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroid injections may offer some pain relief.

Surgery. If discomfort persists, surgery may be necessary, particularly for more serious conditions, such as hallux valgus. There are more than 100 surgical variations, ranging from removing the bump to realigning the toes.

The most common surgery, an office procedure known as bunionectomy, involves shaving down the bone of the big toe joint. In one procedure the surgeon uses a very small incision, through which the bone-shaving drill is inserted. The physician shaves off the bone, guided by feel or x-ray. This technique is not a cure, but patient satisfaction is high and results are long-lasting.

Click the icon to see an illustrated series detailing bunion removal.

More extensive surgeries may be required to realign the toe joint. Although there are variations of each, they generally involve one or more of the following:

Osteotomy (cutting and realigning the joint). Long-term studies on osteotomies report that 90% of patients are satisfied with the procedure.
Exostetectomy (removal of the large bony growth). This technique is only useful when there is no shift in the toe bone itself.
Arthrodesis (removal of damaged portion of the joint, followed by implantation of screws, wires, or plates to hold the bones together until they heal). This is the gold standard procedure for very severe cases or when previous procedures have failed. Most patients report good results.
Arthroplasty (removal of damaged portion of the joint with the goal of achieving a flexible scar). This technique offers symptom relief and faster rehabilitation than arthrodesis, but it can cause deformity and some foot weakness. Arthroplasty tends to be used in older patients. Biologic or synthetic implants for supporting the toes are showing promise as part of this procedure.
Tendon and Ligament Repair. If tendons and ligaments have become too loose, the surgeon may tighten them.

In severe cases, surgeons are testing bone grafts to restore bone length in patients who have had previous bunion surgeries or damage from osteoarthritis.

Complications, though uncommon in even the most complex procedures, can include:

Continued pain
Infection
Possible numbness
Irritation from implants used to support the bone
An excessively shortened metatarsal bone

Recovery from more invasive procedures, such as arthrodesis or osteotomy, may take 6 - 8 weeks, and it can be that long before a patient can put full weight on the foot. In such cases, the patient will need to wear a cast or use crutches. Elderly patients may need wheelchairs.

Treatment: Hammertoes

A hammertoe is a permanent deformity of the toe joint, in which the toe bends up slightly and then curls downward, resting on its tip. When forced into this position long enough, the tendons of the toe shrink, and the toe stiffens into a hammer- or claw-like shape.

Hammertoe is most common in the second toe, but it can develop in any or all of the three middle toes if they are pushed forward and do not have enough room to lie flat in the shoe. The risk is increased when the toes are already crowded by the pressure of a bunion. Risks include:

Lying down for long periods
Diabetes
Diseases that affect the nerves and muscles

Click the icon to see an image of a hammertoe.

Treatment for Hammertoe. At first, a hammertoe is flexible, and any pain it causes can usually be relieved by putting a toe pad, sold in drug stores, into the shoe. To help prevent and ease existing discomfort from hammertoes, shoes should have a deep, wide toe area. As the tendon becomes tighter and the toe stiffens, other treatments, including exercises, splints, and custom-made shoe inserts (orthotics) may help redistribute weight and ease the position of the toe.

Surgery. Patients with severe cases of hammertome may need surgery. If the toe is still flexible, only a simple procedure that releases the tendon may be involved. Such procedures sometimes require only a single stitch and a Band-Aid. If the toe has become rigid, surgery on the bone is necessary, but it can still be performed in the doctor's office. A procedure called PIP arthroplasty involves releasing the ligaments at the joint and removing a small piece of toe bone, which restores the toe to its normal position. The toe is held in this position with a pin for about 3 weeks, and then the pin is removed. One study reported that 92% of patients who had arthroscopy were still pain free after 5 years.

Treatment: Ingrown Toenails

Ingrown toenails can occur on any toe but are most common on the big toes. They usually develop when tight-fitting or narrow shoes put too much pressure on the toenail and force the nail to grow into the flesh of the toe. Incorrect toenail trimming can also contribute to the risk of developing an ingrown toenail. Other causes are:

Fungal infections
Injuries
Abnormalities in the structure of the foot
Repeated impact on the toenail from high-impact aerobic exercise

An ingrown toenail is a condition in which the edge of the toenail grows into the skin of the toe. The big toe is most commonly affected. Symptoms include pain, redness, and swelling around the toenail.

Caring for Toenails. Trim toenails straight across and keep them long enough so that the nail corner is not visible. If the nail is cut too short, it may grow inward. If the nail does grow inward, do not cut the nail corner at an angle. This only trains the nail to continue growing inward. When filing the nails, file straight across the nail in a single movement, lifting the file before the next stroke. Do not saw back and forth. A cuticle stick can be used to clean under the nail.

Treatments. To relieve pain from ingrown toenails, try wearing sandals or open-toed shoes. Soaking the toe for 5 minutes twice a day in a warm water solution of Domeboro or Betadine can help. People who are at increased risk for infections, such as those with diabetes, should have professional treatment.

Antibiotic ointments can treat ingrown toenails that are infected. Apply the ointment by working a wisp of cotton under the nail, especially the corners, to lift the nail up and drain the infection. The cotton will also help force the toenail to grow out correctly. Change the cotton daily, and use the antibiotic consistently.

In severe cases, more intensive treatments are needed. Surgery involves simply cutting away the sharp portion of ingrown nail, removing the nail bed, or removing a wedge of the affected tissue. One study found that orthonyxia, a newer surgical technique that implants a small metal brace into the top of the nail, is as effective as traditional surgical techniques for preventing ingrown toenails from recurring.

Nonsurgical methods can also treat ingrown toenails. One technique uses chemicals to remove the skin. Both sodium hydroxide and phenol may be used, but research shows that sodium hydroxide produces a better outcome and faster recovery than phenol. Other nonsurgical methods include using cauterization (heating), or lasers, to remove the skin.

Treatment: Forefoot Pain

Forefoot pain refers to pain and discomfort felt toward the top of the foot. The rate of forefoot pain and deformity increases with age. When a cause cannot be determined, any pain on the ball of the foot is generally referred to as metatarsalgia.

Forefoot pain may be due to:

Morton's neuroma
Sesamoiditis
Stress fractures

A neuroma usually means a benign tumor of a nerve. However, Morton’s neuroma, also called interdigital neuroma, is not actually a tumor. It is a thickening of the tissue surrounding the nerves leading to the toes. Morton’s neuroma usually develops when the bones in the third and fourth toes pinch together, compressing a nerve. It can also occur in other locations. The nerve becomes enlarged and inflamed. The inflammation causes a burning or tingling sensation and cramping in the front of the foot. Other causes of this condition include:

Tight, poorly-fitting shoes
Injury
Arthritis
Abnormal bone structure

Treatment for Neuromas. Pain from Morton's neuroma can be reduced by massaging the affected area. Roomier shoes (box-toed shoes), pads of various sorts, and cortisone injections in the painful area are also helpful. A combination of cortisone injections and shoe modifications provides better immediate relief than changes in footwear alone. Ultrasound-guided injection of alcohol might also provide relief from Morton's neuroma, research finds.

If these treatments are not effective, the enlarged area may need to be surgically removed. In one long-term study of one surgeon's experience, 85% of patients reported good to excellent satisfaction nearly 6 years after surgery. About 65% were pain free. Some numbness is common afterward, but it rarely bothers patients. Occasionally, the nerve tissue may re-grow and form another neuroma.

Sesamoiditis is an inflammation of the tendons around the small, round bones that are embedded in the head of the first metatarsal bone, which leads to the big toe. Sesamoid bones bear much stress under ordinary circumstances; excessive stress can strain the surrounding tendons. Often there is no clear-cut cause, but sesamoid injuries are common among people who participate in jarring, high-impact activities, such as ballet, jogging, and aerobic exercise.

Treatment for Sesamoiditis. Rest and reducing stress on the ball of the foot are the first lines of treatment for sesamoiditis. A low-heeled shoe with a stiff sole and soft padding inside is all that is usually required. In severe cases, surgery may be necessary.

A stress fracture in the foot, also called fatigue or march fracture, usually results from a break or rupture in any of the five metatarsal bones (mostly the second or third). These fractures are caused by overuse during strenuous exercise, particularly jogging and high-impact aerobics. Women are at higher risk for stress fracture than men.

A fracture in the first metatarsal bone, which leads to the big toe, is uncommon because of the thickness of this bone. If it occurs, however, it is more serious than a fracture in any of the other metatarsal bones because it dramatically changes the pattern of normal walking and weight bearing.

Treatment for Stress Fractures. Patients should seek treatment if pain persists for 3 weeks. In a study of young athletes, treatment after that time reduced the chance that they could return to their sport. Surgery may be needed if conservative measures fail. In most cases, however, stress fractures heal by themselves if you avoid rigorous activities. Some health care providers recommend moderate exercise, particularly swimming and walking. It is best to wear low-heeled shoes with stiff soles. Occasionally, a health care provider may recommend wearing a special wooden shoe and a compressive wrap to make walking more comfortable.

Treatment: Heel Pain

The heel is the largest bone in the foot. Heel pain is the most common foot problem and affects 2 million Americans every year. It can occur in the front, back, or bottom of the heel. Types of heel pain include:

Achilles tendinitis
Bursitis of the heel
Excess pronation
Haglund's deformity
Heel spur syndrome
Plantar fasciitis

Each type of heal pain is described in more detail below. General treatment guidelines are as follows:

The American Orthopaedic Foot and Ankle Society (AOFAS) suggests shoe inserts, medications, and stretching as a first line of therapy for heel pain. One study found that 95% of women who used an insert and did simple stretching exercises for the Achilles tendon and plantar fascia experienced improvement after 8 weeks.
If these treatments fail, the patient may need prescription heel orthotics and extended physical therapy. Surgery may be an option if other methods have failed.

Achilles tendinitis is an inflammation of the tendon that connects the calf muscles to the heel bone. It is caused by small tears in the tendon from overuse or injury. This condition is most common in people who engage in high-impact exercise, particularly jogging, racquetball, and tennis.

People at highest risk for this disorder from these activities are those with a shortened Achilles tendon. Such people tend to roll their feet too far inward when walking, and may bounce when they walk. A shortened tendon can be due to an inborn structural abnormality, or it can develop from regularly wearing high heels.

An inflamed or torn Achilles tendon causes intense pain and affects mobility.

Evidence is uncertain about the best way to treat either acute or chronic Achilles tendinitis. Some approaches include:

Treatments to Relieve Pain and Reduce Inflammation. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin or ibuprofen (Advil), may help ease pain and reduce inflammation. It is also helpful to apply ice for 20 - 30 minutes, four or five times a day. (Note: Corticosteroid injections are sometimes used, although evidence suggests they don't help very much, and they can pose a risk for rupture of the tendon.)

Gentle Stretching. Gentle calf muscle stretches may also help reduce pain and spasms. If the calf is swollen, elevate the leg. Exercise is safe when the heel is no longer swollen or tender, even if pain is still present. If pain increases with exercise, stop immediately.

Laser Therapy. Low-level laser therapy that emits energy directed at pain trigger points has helped some patients. No strong evidence supports its use to date, however.

Surgery vs. Nonsurgical Treatment. Chronic inflammation may lead to rupture of the Achilles tendon. If pain continues, the ruptured tendon will require a cast and perhaps surgery, called tendon transfer. Although some experts believe a cast without surgery is a sufficient treatment for such rupture, there is a chance the tendon may rupture again in the future, even after it heals. Some experts suggest surgery for active people and nonsurgical treatment for older people.

Surgery requires a long incision with a postoperative period of immobilization that can average 6 weeks. Complications can include a significant surgical scar, infection, and muscle atrophy, although surgery reduces pain and preserves foot function in the long term. Less invasive techniques are being tested. In one study, selected patients with ruptured tendons were hospitalized for about 5 days and fitted with special footgear (Variostabil, which continuously raised the back of the foot). The footgear was effective for most patients, and the tendon ruptured again in only 5% of cases.

Bursitis of the heel is an inflammation of the bursa, a small sack of fluid beneath the heel bone. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin or ibuprofen (Advil), and steroid injections will help relieve pain from bursitis. Applying ice and massaging the heel are also beneficial. A heel cup or soft padding in the heel of the shoe reduces direct impact when walking.

Pronation is the normal motion that allows the foot to adapt to uneven walking surfaces and to absorb shock. Excessive pronation occurs when the foot has a tendency to turn inward and stretch and pull the fascia. It can cause not only heel pain, but also hip, knee, and lower back problems.

Haglund's deformity, known medically as posterior calcaneal exostosis, is a bony growth surrounded by tender tissue on the back of the heel bone. It develops when the back of the shoe repeatedly rubs against the back of the heel, aggravating the tissue and the underlying bone. It is commonly called pump bump because it frequently occurs with high heels. (It can also develop in runners, however.)

Treatment for Haglund's Deformity. Applying ice followed by moist heat will help ease discomfort from a pump bump. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin or ibuprofen (Advil), will also reduce pain. Your doctor may recommend an orthotic device to control heel motion. Corticosteroid injections are not recommended because they can weaken the Achilles tendon.

In severe cases, surgery may be necessary to remove or reduce the bony growth. According to one study, however, surgery was not effective for more than 30% of patients and, in fact, the condition worsened in 14% of patients who had surgery. A more recent study reported that surgery cured 90% of cases, but patients took 6 months to 2 years to fully recover. Experts advise patients to try all conservative measures before choosing surgery.

Plantar fasciitis is a common foot problem that accounts for 1 million office visits per year. Plantar fasciitis occurs from small tears and inflammation in the wide band of tendons and ligaments that stretches from the heel to the ball of the foot. This band, much like the tensed string in a bow, forms the arch of the foot and helps serve as a shock absorber for the body.

The term plantar means the sole of the foot, and fascia refers to any fibrous connective tissue in the body. Most people with plantar fasciitis experience pain in the heel with their first steps in the morning. The pain also often spreads to the arch of the foot. The condition can be temporary, or it may become chronic if ignored. Resting can provide relief, but only temporarily.

Heel spurs are calcium deposits that can develop under the heel bone as a result of the inflammation that occurs with plantar fasciitis. Heel spurs and plantar fasciitis are sometimes blamed interchangeably for pain, but plantar fasciitis can occur without heel spurs, and spurs commonly develop without causing any symptoms at all.

Causes of Plantar Fasciitis. The cause of plantar fasciitis is often unknown. It is usually associated with overuse during high-impact exercise and sports. Plantar fasciitis accounts for up to 9% of all running injuries. Because the condition often occurs in only one foot, however, factors other than overuse are likely to be responsible in many cases. Other causes of this injury include poorly-fitting shoes, lack of calf flexibility, or an uneven stride that causes an abnormal and stressful impact on the foot.

Treatment Goals. The three major treatment goals for plantar fasciitis are:

Reducing inflammation and pain
Reducing pressure on the heel
Restoring strength and flexibility

Embarking on an exercise program as soon as possible and using NSAIDs, splints, or heel pads as needed can help relieve the problem. Pain that does not subside with NSAIDs may require more intensive treatments, including leg supports and even surgery.

Exercises to Restore Strength and Flexibility. Stretching the plantar fascia is the mainstay therapy for restoring strength and flexibility. One exercise involves the following:

Put the hands on a wall and lean against them.
Place the uninjured foot on the floor in front of the injured foot.
Raise the heel of the injured foot.
Gently stretch the injured leg and foot.

With stretching treatments, the plantar fascia nearly always heals by itself but it may take as long as a year, with pain occurring intermittently. A moderate amount of low-impact exercise (such as walking, swimming, or cycling) also seems to be beneficial.

Treatment. Inflammation and pain is most commonly treated with ice and over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin or ibuprofen. NSAIDs reduce pain and disability in people with plantar fasciitis when used with other techniques, such as night splints and stretching.

Corticosteroids are powerful anti-inflammatory agents. An injection of a steroid plus a local anesthetic (such as xylocaine) may provide relief in severe cases of plantar fasciitis. (Steroid injections are not used for pain that is only due to heel spurs). For athletes or performers who need immediate relief, an effective method is to administer the steroid dexamethasone using a procedure called iontophoresis, which introduces the drug into the foot's tissue using an electrical current.

Several non-drug approaches can relieve pressure on the heel, including:

Sturdy Shoes and Insoles. It is important to wear comfortable but sturdy shoes that have thick soles, rubber heels, and a sole insole to relieve pressure. (An insole with an arch support might also be helpful.) Cutting a round hole about the size of a quarter in the sole cushion under the painful area may help support the rest of the heel while relieving pressure on the painful spot. Heel cups are not very useful. When combined with exercises that stretch the arch and heel cord, over-the-counter insoles may offer the same relief as prescribed orthotics.
Night Splints. Some evidence suggests that splints worn at night may be helpful for some people. One device, for example, uses an Ace bandage and an L-shaped fiberglass splint to keep the foot stretched while the patient is sleeping. This allows the muscle to heal. One study reported that nearly any splint, regardless of cost, is equally effective in about three-quarters of patients. Although patient compliance may be better with custom-made prescribed orthotics than with tension night splints, one study found they are equally effective in improving pain.
Elevated Heels. Some people report relief from mild symptoms with the use of shoes or cowboy boots that have elevated heels. This approach, however, may not work in some people and is not recommended for anyone with a moderate-to-severe condition. (Heel cups have not been proven to be very useful.)
Orthotics. For severe conditions, such as fallen arches or structural problems that cause imbalance, insoles, called orthotics, molded from a plaster cast of the patient's foot may be needed. (See "Insoles and Orthotics" section).
Extracorporeal Shock Wave Therapy (ESWT). ESWT may be used as an alternative to surgery for patients who have not responded to other treatments. The therapy uses low-dose sound waves to injure the surrounding tissues in the heel, which is believed to trigger healing of the tissues that are causing the pain. Studies show that the treatment provides a very small reduction in heel pain without side effects. It can be considered as an option for patients who haven't responded well to extensive conservative treatment.
Surgery. Surgery may be needed for some patients, typically those who have disabling heel pain that does not respond to other treatments for at least a year. A typical surgery is called instep plantar fasciotomy. It relieves pressure on the nerves that are causing pain by removing and therefore releasing part of the plantar fascia. A less invasive method uses a procedure called endoscopy, which requires smaller incisions. Wearing a below-the-knee walking cast after surgery for 2 weeks may reduce the need for pain relief and speed recovery time compared to the use of crutches.
Botox. Small studies show that injections of botulinum toxin (Botox), a protein used to temporarily paralyze certain muscles, reduces pain and improves patients' future ability to walk. More research is needed on this treatment.

Treatment: Flat Feet

Flat foot, or pes planus, is a defect of the foot that eliminates the arch. The condition is most often inherited. Arches, however, can also fall in adulthood, in which case the condition is sometimes referred to as posterior tibial tendon dysfunction (PTTD). This occurs most often in women over age 50, but it can occur in anyone. The following are risk factors for PTTD:

Wearing high heels for long periods of time is a particular risk for flat feet. Over the years, the Achilles tendon in the back of the calf shortens and tightens, so the ankle does not bend properly. The tendons and ligaments running through the arch then try to compensate. Sometimes they break down, and the arch falls.
Some studies have indicated that the earlier a person starts wearing shoes, particularly for long periods of the day, the higher the risk for flat feet later on.
Other conditions that can lead to PTTD include obesity, diabetes, surgery, injury, rheumatoid arthritis, or the use of corticosteroids.

Some research suggests that flat feet in adults can, over time, actually exert abnormal pressure on the ankle joint that can cause damage. One indirect complication of flat arches may be urinary incontinence or leakage during exercise. The less flexible the arch, the more force reaches the pelvic floor, jarring the muscles that affect urinary continence. Nevertheless, whether flat feet pose any significant problems in adults is unknown. For example, one study on athletes with flat feet indicated that they had no higher risk for leg or foot injuries than did athletes with normal arches.

Treatment for Flat Feet in Children. Doctors usually can't diagnose flat feet until a child is 6 years old. Children with flat feet typically don't have symptoms, and often outgrow the condition. Children who are experiencing symptoms might need to change shoes or wear arch supports. In rare cases, minimally invasive joint insert surgery may be an option.

Treatment for Flat Feet in Adults. In general, conservative treatment for flat feet acquired in adulthood (posterior tibial tendon dysfunction) involves pain relief and insoles or custom-made orthotics to support the foot and prevent progression.

In severe cases, surgery may be required to correct the foot posture, usually with procedures called osteotomies or arthrodesis that typically lengthen the Achilles tendon and adjust tendons in the foot. One procedure uses an implant to support the arch. These procedures have potential complications. Conservative methods should be tried first.

Treatment: Abnormally High Arches

An overly-high arch (hollow foot) can cause problems. Army studies have found that recruits with the highest arches have the most lower-limb injuries and that flat-footed recruits have the least. Contrary to the general impression, the hollow foot is much more common than the flat foot.

Clawfoot, or pes cavus, is a deformity of the foot marked by very high arches and very long toes. Clawfoot is a hereditary condition, but can also occur when muscles in the foot contract or become unbalanced due to nerve or muscle disorders.

Claw toe is a deformity of the foot in which the toes are pointed down and the arch is high, making the foot appear claw-like. Claw toe can be a condition from birth or develop as a consequence of other disorders.

Treatment: Tarsal Tunnel Syndrome

Tarsal tunnel syndrome results from compression of a nerve that runs through a narrow passage behind the inner ankle bone down to the heel. It can cause pain anywhere along the bottom of the foot. It can occur with:

Diabetes
Back pain
Arthritis
Injury to the ankle
Abnormal blood vessels
Scar tissue that press against the nerve

Magnetic resonance imaging (MRI) and the dorsiflexion-eversion test can diagnose this syndrome.

Treatment for Tarsal Tunnel Syndrome. Specially designed shoe inserts called orthotics can relieve pain from tarsal tunnel syndrome, because they help redistribute weight and take pressure off the nerve. Corticosteroid injections may also help. Surgery is sometimes performed, particularly if symptoms persist for more than a year, although its benefits are a matter of debate. Tarsal tunnel syndrome caused by known conditions, such as tumors or cysts, may respond better to surgery than tarsal tunnel syndrome of unknown cause. It can take months after this surgery for a person to recover and resume normal activities. Only experienced surgeons should perform tarsal tunnel syndrome surgery.

Treatment: Foot Injury

If you suspect that you have broken or fractured bones in a toe or foot, call a doctor, who will probably order x-rays. Even if you can walk, you still might have a fracture. People are often able to walk even if a foot bone has been fractured, particularly if it is a chipped bone or a toe fracture.

Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat mild pain caused by muscle inflammation. Aspirin is the most common NSAID. Others include ibuprofen (Motrin, Advil, Nuprin, Rufen), ketoprofen (Actron, Orudis KT), naproxen (Aleve, Naprelan), and tolmetin (Tolectin). A gel containing ibuprofen can be applied to sore joints. Acetaminophen (Tylenol) is not an NSAID, and although it is a mild pain reliever, it will not reduce inflammation. It is important to note that high doses or long-term use of any NSAID can cause gastrointestinal disturbances with sometimes serious consequences, including dangerous bleeding. No one should take NSAIDs for prolonged periods of time without consulting a doctor.

The acronym RICE stands for rest, ice, compression, and elevation -- the four basic elements of immediate treatment for an injured foot.

Rest. Patients should get off injured foot as soon as possible.
Ice. This is particularly important to reduce swelling and promote recovery during the first 48 hours. Wrap a bag or towel containing ice around the injured area on a repetitive cycle of 20 minutes on, 40 minutes off.
Compression. Lightly wrap an Ace bandage around the area.
Elevation. Elevate the foot on several pillows.

Minor injuries like sprains may be treated at home if broken bones are not suspected. The acronym RICE is helpful for remembering how to treat minor injuries: "R" stands for rest, "I" is for ice, "C" is for compression, and "E" is for elevation. Pain and swelling should decrease within 48 hours, and gentle movement may be beneficial, but don't put pressure on a sprained joint until the pain is completely gone (one to several weeks).

Prevention

The American Podiatric Medical Association offers the following tips for preventing foot pain:

Don't ignore foot pain -- it's not normal. If the pain persists, see a doctor who specializes in podiatry.
Inspect feet regularly. Pay attention to changes in color and temperature. Look for thick or discolored nails (a sign of developing fungus), and check for cracks or cuts in the skin. Peeling or scaling on the soles of feet could indicate athlete's foot. Any growth on the foot is not considered normal.
Wash feet regularly, especially between the toes, and dry them completely.
Trim toenails straight across, but not too short. (Cutting nails in corners or on the sides increases the risk for ingrown toenails.)
Make sure shoes fit properly. Purchase new shoes later in the day when feet tend to be at their largest, and replace worn out shoes as soon as possible.
Select and wear the right shoe for specific activities (such as running shoes for running).
Alternate shoes. Don't wear the same pair of shoes every day.
Avoid walking barefoot, which increases the risk for injury and infection. At the beach or when wearing sandals, always use sunblock on your feet, as you would on the rest of your body.
Be cautious when using home remedies for foot ailments. Self-treatment can often turn a minor problem into a major one.
It is critical that people with diabetes see a podiatric physician at least once a year for a checkup. People with diabetes, poor circulation, or heart problems should not treat their own feet, including toenails, because they are more prone to infection.

Skin creams can help maintain skin softness and pliability. A pumice stone or loofah sponge can help get rid of dead skin.

Taking a warm footbath for 10 minutes two or three times a week will keep the feet relaxed and help prevent mild foot pain caused by fatigue. Adding 1/2 cup of Epsom salts increases circulation and adds other benefits. Taking footbaths only when the feet are painful is not as helpful.

In addition to wearing proper shoes and socks, walking often -- and properly -- can prevent foot injury and pain. The head should be erect, the back straight, and the arms relaxed and swinging freely at the side. Step out on the heel, move forward with the weight on the outside of the foot, and complete the step by pushing off the big toe.

Exercises specifically for the toe and feet are easy to perform and help strengthen them and keep them flexible. Helpful exercises include the following:

Raise and curl the toes 10 times, holding each position for a count of five.
Put a rubber band around both big toes and pull the feet away from each other. Count to five. Repeat 10 times.
Pick up a towel with the toes. Repeat five times.
Pump the foot up and down to stretch the calf and shin muscles. Perform for 2 or 3 minutes.

Early Development. The first year of life is important for foot development. Parents should cover their babies' feet loosely, allowing plenty of opportunity for kicking and exercise. Change the child's position frequently. Children generally start to walk at 10 - 18 months. They should not be forced to start walking early. Wearing just socks or going barefoot indoors helps the foot develop normally and strongly and allows the toes to grasp. Going barefoot outside, however, increases the risk for injury and other conditions, such as plantar warts.

Shoes. Children should wear shoes that are light and flexible, and since their feet tend to perspire, their shoes should be made of materials that breathe. Replace footwear every few months as the child's feet grow. Footwear should never be handed down. Protect children's feet if they participate in high-impact sports.

Shoes

In general, the best shoes are well cushioned and have a leather upper, stiff heel counter, and flexible area at the ball of the foot. The heel area should be strong and supportive, but not too stiff, and the front of the shoe should be flexible. New shoes should feel comfortable right away, without a breaking-in period.

Well-fitted shoes with a firm sole and soft upper are the best way to prevent many problems with the feet. They should be purchased in the afternoon or after a long walk, when the feet have swelled. There should be 1/2 inch of space between the longest toe and the tip of the shoe (remember, the longest toe is not always the big toe), and the toes should be able to wiggle upward.

Stand when being measured, and have both feet sized, buying shoes that fit whichever foot is largest. Wear the same socks as you would regularly wear with the new shoes. Women who are accustomed to wearing pointed-toe shoes may prefer the feel of tight-fitting shoes, but with wear their tastes may adjust to shoes that are less confining and properly fitted.

Ideally, the shoe should have a removable insole. Thin, hard soles may be the best choice for older people. Elderly people wearing shoes with thick inflexible soles may be unable to sense the position of their feet relative to the ground, significantly increasing the risk for falling.

High heels are the major cause of foot problems in women. Although people believe that foot binding is a problem limited to Chinese women of the past, many fashionable high heels are designed to constrict the foot by up to an inch. Women who insist on wearing high-heeled shoes should at least look for shoes with wide toe room, reinforced heels that are relatively wide, and cushioned insoles. They should also keep the amount of time they spend wearing high heels to a minimum.

The way shoes are laced can be important for preventing specific problems. Laces should always be loosened before putting shoes on. People with narrow feet should buy shoes with eyelets farther away from the tongue than people with wider feet. This makes for a tighter fit for narrower feet and a looser fit for wider feet. If, after tying the shoe, less than an inch of tongue shows, the shoes are probably too wide. Adjust tightness both at the top and bottom of the shoe. When shoes with high arches cause pain, skip eyelets when lacing them to relieve pressure.

If shoes need breaking in, place moleskin pads next to areas on the skin where friction is likely to occur. Once a blister occurs, moleskin is not effective. Change shoes during the day, and rotate between different pairs of shoes. As soon as the heels show noticeable wear, replace the shoes or their heels.

Avoid extreme variations between exercise, street, and dress shoes.

Exercise and Sports. Shoes purchased for exercise should be specifically designed for a person's preferred sport. For instance, a running shoe should especially cushion the forefoot, while tennis shoes should emphasize ankle support. Athletic socks are almost as important as shoes. Experts often recommend padded acrylic socks.

Occupational Footwear. Because a number of occupations put the feet in danger, workers in high-risk jobs should be sure their footwear is protective. For example, non-electric workers at risk for falling or rolling objects or punctures should wear shoes with steel toes and possibly other metal foot guards. Electric workers should wear footgear with no metal parts (or insulated steel toes) and rubber soles and heels. Chemical workers should wear shoes made of synthetics or rubber, not leather.


Aerobic Dancing	Sufficient cushioning to absorb shock and pressure, which should be many times greater than shock from walking. Arches that maintain side-to-side stability. Thick upper leather support. Box toe. Orthotics may be required for people with ankles that over-turn inward or outward. Soles should allow for twisting and turning.
Cycling	Rigid support across the arch to prevent collapse during pedaling. Heel lift. Cross-training or combo hiking/cycling shoes may be sufficient for the casual biker. Toe clips or specially designed shoe cleats for serious cyclers. In some cases, orthotics may be needed to control arch and heel and balance the forefoot.
Running	Sufficient cushioning to absorb shock and pressure. Fully bendable at the ball of the foot. Enough traction on the sole to prevent slipping. Consider insole or orthotic with arch support for problem feet.
Tennis	Allows side-to-side sliding. Low-traction sole. Snug fitting heel with cushioning. Padded toe box with adequate depth. Soft-support arch.
Walking	Lightweight. Breathable upper material (leather or mesh). Wide enough to accommodate ball of the foot. Firm padded heel counter that does not bite into heel or touch anklebone. Low heel close to ground for stability. Good arch support. Front provides support and flexibility.

Insoles and Orthotics

Insoles are flat cushioned inserts that are placed inside the shoe. They are designed to reduce shock, provide support for heels and arches, and absorb moisture and odor. In general, they can be very helpful for many people.

People respond very differently to specific insoles. What may work for one person may not for another. Consider the thickness of socks when purchasing insoles to be sure they do not squeeze the toes up against the shoes. Insoles can be purchased in athletic and drug stores. Shoe stores that specialize in foot problems often sell customized, but more expensive, insoles. In general, over-the-counter insoles offer enough support for most people's foot problems. Most well-known brands of athletic shoes have built-in insoles.

Brands and Materials. There are many types of insoles available. They are composed of various materials, such as cork, leather, plastic foam, and rubber. Very effective insoles are now made from viscoelastic polymers (such as Sorbothane, Airplus, Spenco, Dr. Scholl's Massaging Gel, and others), which are gel-like materials that act both as liquids and solids.

Heel Cushions for Shortened Achilles Tendons. People who have developed short, tightened Achilles tendons (usually women who have worn high-heeled shoes for prolonged periods) should consider using heel cushions. Like insoles, heel cushions are inserted inside the shoes. They should be at least 1/8 inch thick, but not more than 1/4 inch thick.

For severe conditions, such as fallen arches or structural problems that cause imbalance, podiatrists or physicians may need to fit and prescribe orthotics, or orthoses, which are insoles molded from a plaster cast of the patient's foot. Orthotics are usually categorized as rigid, soft, or semi-rigid.

Before seeking prescription orthotics, people with less severe problems should consider testing the lower-priced, over-the-counter insoles.

Types of orthotics include:

Rigid Orthotics. Rigid orthotics are used to control motion in two major foot joints that lie directly below the ankle. They are often used to prevent excessive pronation (the turning in of the foot) and are useful for people who are very overweight or have uneven leg lengths. Some experts warn that rigid orthotics may cause sesamoiditis or benign tumors from pinched nerves.
Soft Orthotics. Soft orthotics are designed to absorb shock, improve balance, and remove pressure from painful areas. They are made from a lightweight material and are often beneficial for people with diabetes or arthritis. Soft orthotics need to be replaced periodically, and because they are bulkier than rigid orthotics, they may require larger shoes.
Semi-Rigid Orthotics. Semi-rigid orthotics are designed to provide balance, often for a specific sport. They are typically made of layers of leather and cork reinforced by silastic.

Running 101: Negative Splits

FitSugar — Wed, 20 May 2009 04:30:00 -0700

There's a bunch of jargon associated with running, which is ironic since it is one of the easiest forms of exercise to do - just lace up your shoes and go. One term to add to your list of fitness terms is "negative splits," which means running faster for the second half of your run or race than you did for the first half. This increase in speed puts you in the negative in terms of time, but here are a couple of positives for doing so.

Negative splits help you warm up thoroughly. Going slower earlier in your run means your joints, muscles, heart, and lungs will be primed to pick up speed in the second half of your run.
Running more slowly at the beginning of a race will help you conserve energy so you can finish strong. To have the discipline to race this way, you need to practice negative splits on your training runs.

For a couple of tips on training with negative splits, just read more.

An easy way to incorporate a negative split run in your training is to map out an "out and back" run, so you turn around at the halfway point. Simply run faster for the second half of the run. This will acclimate your body to speeding up halfway through a run.
When doing intervals, make the second half of each speed interval faster than the first half. This is yet another way to make intervals more challenging.

Are you going to train negative?

Highlights

Chronic Conditions and Exercise:

A new study found that aerobic and resistance training significantly reduced fatigue in men undergoing radiation treatments for prostate cancer. Fatigue is a common side effect of such treatments.
Doctors at the Mayo Clinic found that exercise improves the physical and emotional well-being of patients with Alzheimer's disease. The patients exercised for as little as 60 minutes each week. Doctors noted improvements in areas ranging from depression to wandering.

Exercise and Smoking:

A 2007 review of existing studies found that moderate exercise, for as little as 5 minutes, can help combat the nicotine withdrawal symptoms people experience when they try to stop smoking.

Exercise and Aging:

A 2006 report found that older and elderly adults who exercised twice a week for 4 months significantly increased their body strength, flexibility, balance, and agility. The average age of the study participants was 83.5.

Before and After Exercising:

You should do warm-up exercises for 5 - 10 minutes at the beginning of an exercise session. Low-level aerobic exercise is the best warm-up.
To cool down, you should walk slowly until your heart rate is 10 - 15 beats above your resting heart rate. Stopping too suddenly may sharply reduce blood pressure or cause muscle cramping.
You must be careful when stretching during your warm-up to avoid injuring cold muscles.

Definitions:

Aerobic exercise: Aerobic exercise forces the heart and lungs to work harder for longer periods. It builds endurance, improves blood flow throughout the body, and increases the levels of "good" cholesterol.
Resistance Training: Resistance training works muscles against a force (usually weights). It burns fat and builds muscle.

Introduction

Everyone's goal of living a long and healthy life should include a healthy diet, regular exercise, and maintaining normal weight. The combination of inactivity and eating the wrong foods is the second most common preventable cause of death in the United States (smoking is the first).

Most research on the benefits of exercise focuses on heart protection. Studies clearly show that exercise helps the heart. In addition, new studies are reporting that even people at higher risk for heart disease may lower their risk of dying from it if they exercise.

Evidence suggests that our genes evolved to favor exercise. In other words, during prehistoric times, if a person couldn't move quickly and wasn't strong, he or she died. Those who were fit survived to reproduce and pass on these "fitter" genes. Some researchers believe that with our current inactive lifestyle, these genes produce a number of bad effects, which can lead to many chronic illnesses.

The benefits of exercise include:

Improved oxygen delivery throughout the body
Improved metabolic processes - the way the body breaks down and builds necessary substances
Improved strength and endurance
Decreased body fat
Improved movement of joints and muscles
Improved sense of well-being

In addition, exercise can help change other dangerous lifestyle habits. A 2007 review of existing studies found that moderate exercise, for as little as 5 minutes at a time, can help combat the nicotine withdrawal symptoms people experience when they try to stop smoking.

No one is too young or too old to exercise. The United States Surgeon General recommends at least 30 minutes of moderate exercise, such as brisk walking, nearly every day. However, vigorous exercise carries risks that people should discuss with a doctor. You should always check with your doctor before starting a new exercise program, especially if you have any of the following risk factors:

History of smoking
Obesity
Family history of a long-term disease
A symptom you haven’t told your doctor about
Chest pain
Shortness of breath
Heart palpitations
Blood clots
Infections
Fever
Unexplained weight loss
Foot or ankle sores that won’t heal
Joint swelling
Pain or trouble walking after a fall
Eye injury or eye surgery
Hernia
Hip surgery

Fifty percent of all people who begin a vigorous training program drop out within a year. The key to reaching and maintaining physical fitness is to find activities that are exciting, challenging, and satisfying.

Recommended Exercise Methods

A few simple rules are helpful as you develop your own routine.

Don't eat for 2 hours before vigorous exercise.
Drink plenty of fluids before, during, and after a workout.
Adjust your activity level according to the weather, and reduce it when you are fatigued or ill.
When exercising, listen to the body's warning symptoms, and consult a doctor if exercise causes chest pain, irregular heartbeat, undue fatigue, nausea, unexpected breathlessness, or light-headedness.

Heart rate is the standard guide for determining aerobic exercise intensity. It can be determined by counting one's own pulse or with the use of a heart rate monitor. To feel your own pulse, press the first two fingers of one hand gently down on the inside of the wrist or under the jaw on the right or left side of the front of the neck. You should feel a faint pounding as blood passes through the artery. Each pounding is a beat.

There are different types of heart rates.

Resting heart rate. The average heart rate for a person at rest is 60 - 80 beats per minute. It is usually lower for people who are physically fit, and often rises as you get older. You can determine your resting heart rate by counting how many times your heart beats in one minute. The best time to do this is in the morning after a good night’s sleep before you get out of bed.

Maximum heart rate. To determine your own maximum heart rate per minute subtract your age from 220. For example, if you are 45, you would calculate your maximum heart rate as follows: 220 - 45= 175.

Target heart rate. Your target rate is 50 - 75% of your maximum heart rate. You should measure your pulse off and on while your exercise to make sure you stay within this range. After about 6 months of regular exercise, you may be able to increase your target heart rate to 85% (but only if you can comfortably do so).

Certain heart medications may lower your maximum and target heart rates. Always check with your doctor before starting an exercise program.

Note: Swimmers should use a heart rate target of 75% of the maximum and then subtract 12 beats per minute. The reason for this is that swimming will not raise the heart rate quite as much as other sports because of the so-called "diving reflex," which causes the heart to slow down automatically when the body is immersed in water.


Age	Low	High
	(50% max.)	(75% max.)
20	100	150
30	95	142
40	90	135
50	85	127
60	80	120

VO2 Max. Serious exercisers may use a VO2 max calculation, which measures the amount of oxygen consumed during intensive, all-out exercise. The most accurate testing method uses computers, but anyone can estimate V02 without instrumentation (with an accuracy of about 95%):

After running at top pace for 15 minutes, round off the distance run to the nearest 25 meters.
Divide that number by 15.
Subtract 133.
Multiply the total by 0.172, then add 33.3.

Olympic and professional athletes train for VO2 max levels above 80. But for the average person interested in fitness, a VO2 max equaling between 50 and 80 is considered an excellent score for overall fitness.

Warming up and cooling down are important parts of every exercise routine. They help the body make the transition from rest to activity and back again, and can help prevent soreness or injury, especially in older people.

Warm-up exercises should be practiced for 5 - 10 minutes at the beginning of an exercise session. Older people need a longer period to warm up their muscles. Low-level aerobic exercise such as brisk walking, swinging the arms, or jogging in place, is the best approach.
To cool down, you should walk slowly until the heart rate is 10 - 15 beats above your resting heart rate. Stopping too suddenly can sharply reduce blood pressure, and is dangerous for older people. It may also cause muscle cramping.
Stretching may be appropriate for the cooling down period, but it must be done carefully for warming up because it can injure cold muscles. (There is no clear evidence, however, that stretching reduces muscle injuries.)

Warming up before exercise and cooling down after is just as important as the exercise itself. By properly warming up the muscles and joints with low-level aerobic movement for 5 - 10 minutes, one may avoid injury and build endurance over time. Cooling down after exercise by walking slowly, then stretching muscles, may also prevent strains and blood pressure fluctuation.

For most people, exercise may be divided into three general categories:

Aerobic or endurance
Strength or resistance
Flexibility

A balanced program should include all three. Speed training is also a major category, but generally only competitive athletes practice it.

Benefits of Aerobic Exercise. Regular aerobic exercise provides the following benefits:

Builds endurance
Keeps the heart pumping at a steady and high rate for a long time
Boosts HDL ("good") cholesterol levels
Helps control blood pressure
Strengthens the bones in the spine
Helps maintain normal weight
Improves one's sense of well-being

Types of Aerobic Exercise. Aerobic exercise is usually categorized as high or low impact. Examples of each include the following:

Low- to moderate-impact exercises: Walking, swimming, stair climbing, step classes, rowing, and cross-country skiing. Nearly anyone in reasonable health can engage in some low- to moderate-impact exercise. Brisk walking burns as many calories as jogging for the same distance and poses less risk for injury to muscle and bone.
High-impact exercises: Running, dance exercise, tennis, racquetball, squash. High-impact exercises should be performed no more than every other day, and less often for those who are overweight, elderly, out of condition, or have an injury or other medical problem that would rule out high-impact.

Aerobic Regimens. As little as one hour a week of aerobic exercises is helpful, but 3 - 4 hours per week are best. Some research indicates that simply walking briskly for 3 or more hours a week reduces the risk for coronary heart disease by 65%. In general, the following guidelines are useful for most individuals:

For most healthy young adults, the best approach is a mix of low- and higher-impact exercise. Two weekly workouts will maintain fitness, but three to five sessions a week are better.
People who are out of shape or elderly should start aerobic training gradually. For example, they may start with 5 - 10 minutes of low-impact aerobic activity every other day and build toward a goal of 30 minutes per day, three to seven times a week. (For heart protection, frequency of exercises may be more important than duration.)
Swimming is an ideal exercise for many elderly and certain people with physical limitations, including pregnant women, individuals with muscle, joint, or bone problems, and those who suffer from exercise-induced asthma.
People who seek to lose weight should aim for six to seven low-impact workouts a week.

One way of gauging the optimal intensity of exercise is to aim for a "talking pace," which is enough to work up a sweat and still be able to converse with a friend without gasping for breath. As fitness increases, the "talking pace" will become faster and faster.

Shoes. All that's really necessary for a workout is a good pair of shoes that are made well and fit well. They should be broken in, but not worn down. They should support the ankle and provide cushioning for impact sports such as running or aerobic dancing. Airing out the shoes and feet after exercising reduces chances for skin conditions such as athlete's foot.

Clothing. Comfort and safety are the key words for workout clothing. For outdoor nighttime exercise, a reflective vest and light-colored clothing must be worn. Bikers, roller bladers, and equestrians should always wear safety devices such as helmets, wrist guards, and knee and elbow pads. Goggles are mandatory for indoor racquet sports. For vigorous athletic activities, such as football, ankle braces may be more effective than tape in preventing ankle injuries.

Aerobic-Exercise Equipment. Home aerobic exercise machines can be adapted to any fitness level and used day or night. Before investing in any exercise machine, however, it is wise to first test it at a gym. In addition, initial supervised training when using these machines can reduce the risk of injury that might occur with self-instruction.

Very inexpensive exercise machines tend to be flimsy and hard to adjust, but many sturdy machines are available at moderate prices. The higher-end models may utilize computers to record calories burned, speed, and mileage. While their readouts may provide motivation and gauge the intensity of a workout, however, they are not always accurate.

The following are a few observations on specific equipment:

A good floor mat is important to provide cushioning for all home exercises.
A simple jump rope improves aerobic endurance for people who are able to perform high-impact exercise. Jumping rope should be done on a floor mat plus a surface that has some give to avoid joint injury.
For burning calories, the treadmill has been ranked best, followed by stair climbers, the rowing machine, cross-country ski machine, and stationary bicycle. (Elliptical trainers, however, may be even better than treadmills for increasing heart rate, calorie expenditure, and oxygen consumption.)
Stationary bikes condition leg muscles and are fairly economical and easy to use safely. The pedals should turn smoothly, the seat height should adjust easily, and the bike's computer should be able to adjust intensity.
Stair machines also condition leg muscles. They offer very intense, low-impact workouts and may be as effective as running with less chance of injury.
Rowing and cross-country ski machines exercise both the upper and lower body.


Aerobic dancing	Sufficient cushioning to absorb shock and pressure that are many times greater than ordinary walking. Arches that maintain side-to-side stability. Thick upper leather support. Toe-box. Orthotics may be required for people with ankles that over-turn inward or outward. Soles should allow for twisting and turning.
Cycling	Rigid support across the arch to prevent collapse during pedaling. Heel lift. Cross-training or combination hiking/cycling shoes may be sufficient for casual bikers. Toe clips or specially designed shoe cleats for serious cyclers. In some cases, orthotics may be needed to control arch and heel and balance forefoot.
Running	Sufficient cushioning to absorb shock and pressure. Fully bendable at the ball of the foot. Sufficient traction on sole to prevent slipping. Consider insoles or orthotics with arch support for problem feet.
Tennis	Allow side-to-side sliding. Low-traction soles. Snug fitting heels with cushioning. Padded toe box with adequate depth. Soft-support arch.
Walking	Lightweight. Breathable upper material (leather or mesh). Wide enough to accommodate ball of the foot. Firm padded heel counter that does not bite into heel or touch ankle bone. Low heel close to ground for stability. Good arch support. Front provides support and flexibility.

Benefits of Strength Exercise. While aerobic exercise increases endurance and helps the heart, it does not build upper body strength or tone muscles. Strength-training exercises provide the following benefits:

Build muscle strength while burning fat
Help maintain bone density
Improve digestion

It is also associated with a lower risk for heart disease, possibly because it lowers LDL (the so-called "bad") cholesterol levels.

Strength exercise is beneficial for everyone, even people in their 90s. It is the only form of exercise that can slow and even reverse the decline in muscle mass, bone density, and strength that occurs with aging. Please note: People at risk for cardiovascular disease should not perform strength exercises without checking with a doctor.

Types of Muscle Contractions. There are three types of muscle contractions involved in strength training:

Isometric contractions do not change the length of the muscle. An example is pushing against a wall.
Concentric contractions shorten muscles. An example is the "up" phase of a bicep curl.
Eccentric contractions lengthen muscles. An example is the "down" phase as weights are lowered.

Click the icon to see an image of isometric exercise.

Strength-Training Regimens. Strength training involves intense and short-duration activities. For beginners, adding 10 - 20 minutes of modest strength training two to three times a week may be appropriate. The following are some guidelines for starting a strength regimen:

The sequence of a strength training session should begin with training large muscles and multiple joints at higher intensity and end with small muscle and single joint exercises at lower intensities.
Both shortening and lengthening muscle actions should be performed. Emphasizing the movements that lengthen muscles is of increasing interest. This approach involves slowing and increasing the duration of these "down" movements. It appears to significantly increase blood flow, and some evidence suggests it may achieve stronger muscles more quickly. It may also improve heart function compared to standard movements. Exercises that lengthen muscles may be particularly beneficial for older people and some people with chronic health problems. This type of training increases the risk for muscle soreness and injury, however, and this approach is still controversial.
Strength training involves moving specific muscles in the same pattern against a resisting force (such as a weight) for a preset number of times. This is called a repetition. Students should first choose a weight that is about half of what would require a maximum effort in one repetition. In other words, if it would take maximum effort to do a single repetition with a 10-pound dumbbell, the person would start with a five-pound dumbbell. In the beginning, most people can start with one set of 8 - 15 repetitions per muscle group with low weights. As individuals are able to perform one or two repetitions over their routine, weights can be increased by 2 - 10%.
Breathe slowly and rhythmically. Exhale as the movement begins. Inhale when returning to the starting point.
The first half of each repetition typically lasts 2 - 3 seconds. The return to the original position lasts 4 seconds.
An alternative technique called "super slow" training stretches out one repetition to a 14-second count. This method places far more stress on the muscle group, so fewer repetitions are needed. A full week of recovery is required before repeating this workout. The goal is to initiate changes in the muscles so that the body continues to burn calories after the exercise. Some people report dramatic results from this approach, but scientific proof of these claims is not available. It is a very tedious workout, and people have a hard time sticking with it. People with high blood pressure should not use this approach.
Joints should be moved rhythmically through their full range of motion during a repetition. Do not lock up the joint while exercising it.
For maximum benefit, one should allow 48 hours between workouts for full muscle recovery.

Strength-Training Equipment. Unlike aerobic exercise, strength training almost always requires some equipment. Strength-training equipment does not, however, have to cost anything.

Any heavy object that can be held in the hand, such as a plastic bottle filled with sand or water, can serve as a weight.
Dumbbells (1 - 10 pounds) and resistance bands are inexpensive, portable, and effective.
Wearable weights help strengthen and tone the upper body.
Ankle weights strengthen and tone muscles in the lower body. Wearable ankle weights should not be worn during high-impact aerobics or jumping.
Hand grips strengthen arms and are good for relieving tension.
A pull-up bar can be mounted in a doorway for chin-ups and pull-ups.

More elaborate and expensive home equipment for working body muscles is also available, costing from $100 to over $1,000. No one should purchase or use strength-training equipment without instruction from a professional.

Benefits of Flexibility Training. Flexibility training uses stretching exercises. Many stretching exercises are particularly beneficial for the back. In general, flexibility training provides the following benefits:

Prevents cramps, stiffness, and injuries
Improves joint and muscle movement (improved range of motion)

Certain flexibility practices, such as yoga and tai chi, also involve meditation and breathing techniques that reduce stress. Such practices appear to have many health and mental benefits. They may be very suitable and highly beneficial for older people, and for patients with certain chronic diseases.

Click the icon to see an image of flexibility exercise.

Flexibility Training Regiments. Doctors recommend performing stretching exercises for 10 to 12 minutes at least three times a week. The following are some general guidelines:

When stretching, exhale and extend the muscles to the point of tension, not pain, and hold for 20 - 60 seconds. (Beginners may need to start with a 5- to 10-second stretch.)
Breathe evenly and constantly while holding the stretch.
Inhale when returning to a relaxed position. Holding your breath defeats the purpose; it causes muscle contraction and raises blood pressure.
When doing stretches that involve the back, relax the spine to keep the lower back flush with the mat, and to work only the muscles required for changing position (often these are only the abdominal muscles).

Studies continue to show that it is never too late to start exercising. A report published in the February 2006 Journal of Aging and Health found that elderly adults who exercised twice a week for four months significantly increased their body strength, flexibility, balance, and agility. The exercise program included walking and lifting weights. The average age of the study participants was 83.5. The study adds further evidence that even small improvements in physical fitness and activity can prolong life and independent living.

Still, about half of Americans over 60 describe themselves as sedentary (inactive). According to a 2004 report by the Centers for Disease Control and Prevention, approximately 12% of people aged 65 - 75 years and 10% of people aged 75 years or older meet current recommendations for strength training.

The following tips for exercising may be helpful:

Any older person should have a complete physical and medical examination, as well as professional instruction, before starting an exercise program.
Start low and go slow. For sedentary, older people, one or more of the following programs may be helpful and safe: Low-impact aerobics, gait (step) training, balance exercises, tai chi, self-paced walking, and lower legs resistance training, using elastic tubing or ankle weights. Even in the nursing home, programs aimed at improving strength, balance, gait, and flexibility have significant benefits.
Strength training assumes even more importance as one ages, because after age 30 everyone undergoes a slow process of muscular erosion. The effect can be reduced or even reversed by adding resistance training to an exercise program. As little as one day a week of resistance training improves overall strength and agility. Strength training also improves heart and blood vessel health.
Power training, which aims for the fastest rate at which a muscle or muscle group can perform work, may be particularly helpful for older women in strengthening muscles and preventing falls.
Flexibility exercises promote healthy muscle growth and help reduce the stiffness and loss of balance that accompanies aging.
Chair exercises may be performed by people who are unable to walk.
Older women are at risk for incontinence accidents during exercise. This can be reduced or prevented by performing Kegel exercises, limiting fluids (without risking dehydration), going to the bathroom frequently, and using leakage prevention pads or insertable devices.

Exercise's Effects on the Heart

Inactivity is one of the major risk factors for heart disease. However, exercise helps improve heart health, and can even reverse some heart disease risk factors.

Like all muscles, the heart becomes stronger as a result of exercise, so it can pump more blood through the body with every beat and continue working at maximum level, if need be, with less strain. The resting heart rate of those who exercise is also slower, because less effort is needed to pump blood.

A person who exercises often and vigorously has the lowest risk for heart disease, but any amount of exercise is beneficial. Studies consistently find that light-to-moderate exercise is even beneficial in people with existing heart disease. Note, however, that anyone with heart disease should seek medical advice before beginning a workout program.

The heart is a large muscular organ that pumps blood throughout the body. Valves inside the heart open and close. This controls how much blood enters or leaves the heart.

Exercise has a number of effects that benefit the heart and circulation (blood flow throughout the body). These benefits include improving cholesterol and fat levels, reducing inflammation in the arteries, assisting weight loss programs, and helping to keep blood vessels flexible and open. Studies continue to show that physical activity and avoiding high-fat foods are the two most successful means of reaching and maintaining heart-healthy levels of fitness and weight.

The American Heart Association recommends that individuals perform moderately-intense exercise for at least 30 minutes on most days of the week. This recommendation supports similar exercise guidelines issued by the Centers for Disease Control and Prevention, and the American College of Sports Medicine.

Coronary Artery Disease. People who maintain an active lifestyle have a 45% lower risk of developing heart disease than do sedentary people. Experts have been attempting to define how much exercise is needed to produce heart benefits. In 2002, a well-conducted study on overweight adults confirmed previous research that reported beneficial changes in cholesterol and lipid levels, including lower LDL levels (bad cholesterol), even when people performed low amounts of moderate- or high-intensity exercise such as walking or jogging 12 miles a week. However, more intense exercise is required to significantly change cholesterol levels, notably increasing HDL (good cholesterol). An example of this kind of program would be jogging about 20 miles a week. Such benefits in the study occurred even with very modest weight loss, suggesting that overweight people who have trouble losing pounds can still achieve considerable heart benefits by exercising.

Some studies suggest that for the greatest heart protection, it is not the duration of a single exercise session that counts but the total daily amount of energy expended. Therefore, the best way to exercise may be in multiple short bouts of intense exercise, which can be particularly helpful for older people.

Resistance (weight) training has also been associated with heart protection. It may offer a complementary benefit to aerobics by reducing LDL levels. Exercises that train and strengthen the chest muscles may prove to be very important for patients with angina.

Effects of Exercise on Blood Pressure. Regular exercise helps keep arteries elastic (flexible), even in older people. This, in turn, ensures good blood flow and normal blood pressure. Sedentary people have a 35% greater risk of developing high blood pressure than athletes do.

Click the icon to see the risks associated with untreated hypertension.

It should be noted that high-intensity exercise may not lower blood pressure as effectively as moderate-intensity exercise. In one study, moderate exercise (jogging 2 miles a day) controlled high blood pressure so well that more than half the patients who had been taking drugs for the condition were able to discontinue their medication. However, a small study published in 2005 suggests that moderate exercise does not have a significant impact on systolic blood pressure (the top number) in older adults. While those who exercised did have notable drops in both the top and lower (diastolic) blood pressure levels, the only statistically significant change was the decrease in the lower number.

Experts recommend at least 30 minutes of exercise on most -- if not all -- days. Studies show that yoga and tai chi, an ancient Chinese exercise involving slow, relaxing movements, may lower blood pressure almost as well as moderate-intensity aerobic exercises.

Click the icon to see an image of someone practicing yoga.

Anyone with existing high blood pressure should discuss an exercise program with their doctor. Before starting to exercise, people with moderate-to-severe high blood pressure should lower their pressure, and be able to control it with medications. Everyone, and especially people with high blood pressure, should breathe as normally as possible through each exercise. Holding the breath increases blood pressure.

Effects of Exercise on Heart Failure. Traditionally, heart failure patients have been discouraged from exercising. Now, exercise performed under medical supervision is proving to be helpful for select patients with stable heart failure.

Studies continue to report benefits from exercise training. In one study, heart failure patients as old as 91 years old increased their oxygen use significantly, after 6 months of supervised treadmill and stationary bicycle exercises.
Progressive resistance training may be particularly useful for heart failure patients, since it strengthens muscles, which commonly weaken in this disorder. Even simply performing daily handgrip exercises can improve blood flow through the arteries.

Experts warn, however, that exercise is not appropriate for all heart failure patients.

All stroke survivors should have a pre-exercise evaluation done by their doctor before starting an exercise program.

The effects of exercise on stroke are less established than those on heart disease, but most studies show benefits. The following are some examples:

According to one major analysis, men cut their risk for stroke in half if their exercise program was roughly equivalent to about an hour of brisk daily walking 5 days a week. In the same study, exercise that involved recreation was more protective against stroke than exercise routines consisting simply of walking or climbing.
A 2000 study of women also found substantial protection from stroke in brisk walking or striding (rather than casual walking).

Anyone with heart disease or risk factors for developing heart disease or stroke should seek medical advice before beginning a workout program. Patients with heart disease can nearly always exercise safely as long as they work out under medical supervision. Still, it is often difficult for a doctor to predict health problems that might arise as the result of an exercise program. At-risk individuals should be very aware of any symptoms warning of harmful complications while they exercise.

Some experts believe that anyone over 40 years old, whether or not they are at risk for heart disease, should have a complete physical examination before starting or intensifying an exercise program. Some doctors use a questionnaire for people over 40 to help determine whether they require such an examination. The questions they use are as follows:

Has any doctor previously recommended medically supervised activity because of a heart condition?
Is chest pain brought on by physical activity?
Has chest pain occurred during the previous month?
Does the person faint or fall over from dizziness?
Is bone or joint pain intensified by exercise?
Has medication been prescribed for hypertension (high blood pressure) or heart problems?
Is the person aware of or has a doctor suggested any physical reason for not exercising without medical supervision?

Those who answer "yes" to any of the above questions should have a complete medical examination before developing an exercise program.

Stress Test. A stress test helps determine the risk for a heart problem resulting from exercise. Anyone with a heart condition or history of heart disease should have a stress test before starting an exercise program. Experts currently also recommend this test before a vigorous exercise program for older persons who are sedentary, even in the absence of known or suspected heart disease. The test is expensive, however, and some experts believe that it may not be necessary for many older people with no evident health problems or risk factors.

A small percentage of heart attacks occur after heavy physical work.

High-Risk Individuals. In general, the following people should avoid intense exercise or start it only with careful monitoring:

People who have certain medical conditions: These conditions include uncontrolled diabetes, uncontrolled seizures, uncontrolled high blood pressure, a heart attack within the previous 6 months, heart failure, unstable angina, significant aortic valve disease, or aortic aneurysm.
People with moderate-to-severe hypertension: Experts generally recommend that moderate or severe high blood pressure (systolic blood pressure over 160 mm Hg or diastolic (bottom number) pressure over 100 mm Hg) should be brought to lower levels before a person starts a vigorous exercise program.
Sedentary people should be cautious. One major study found that sedentary people who throw themselves into a grueling workout significantly increase their risk of heart attack.
Episodes of exercise-related sudden death in young people are rare but of great concern. Some are preceded by fainting, which is due to a sudden and severe drop in blood pressure. It should be noted that fainting is relatively common in athletes, and is dangerous only in people with existing heart conditions. Young people with genetic or congenital (present at birth) heart disorders should avoid intensive competitive sports.
Anabolic steroids or products containing ephedra have been associated with cases of stroke, heart attack, and even death.

The risk for heart attack from exercise should be kept in perspective, however. Some form of exercise, carefully personalized, has benefits for most of the individuals mentioned above. In many cases, particularly when the only risk factors are a sedentary lifestyle and older age, exercise can often be increased over time until it is intense.

Hazardous Activities for High-Risk Individuals. The following activities may pose particular dangers for high-risk individuals:

Intense workouts (snow shoveling, slow jogging, speed walking, tennis, heavy lifting, heavy gardening) may be particularly hazardous for people with risk factors for heart disease, especially older people. They tend to stress the heart, raise blood pressure for a brief period, and may cause spasms in the arteries leading to the heart. (See image: Coronary Artery Spasm)
Some studies suggest that competitive sports, which couple intense activity with aggressive emotions, are more likely to trigger a heart attack than other forms of exercise.

Listening for Warning Signs. It should be noted that according to one study, at least 40% of young men who die suddenly during a workout have previously experienced, and ignored, warning signs of heart disease. In addition to avoiding risky activities, the best preventive tactic is simply to listen to the body and seek medical help at the first sign of symptoms during or following exercise. These symptoms include the following:

Irregular heartbeat
Shortness of breath
Chest pain

Exercise's Effects on Diabetes

Moderate aerobic exercise can lower your risk for type 2 diabetes. An important study found that adults who worked out 2 and 1/2 hours a week cut their risk by 58%.

Exercise has positive benefits for those who have diabetes. It can lower blood sugar, improve insulin sensitivity, and strengthen the heart. Strength training, which increases muscle and reduces fat, may be particularly helpful for people with diabetes, but more evidence is needed to confirm this theory. One study reported that yoga helped patients with type 2 diabetes reduce their need for oral medications.

In 2005, researchers found that people with type 2 diabetes who walked a minimum of 3 miles every day were in better health, and had lower medical expenses, after 2 years of such exercise. Those who remained sedentary for that time period experienced a decline in their overall health and higher health care-related expenses. Study participants who worked out for an average of 38 minutes per day lowered their blood pressure, cholesterol ,and A1C levels (glucose concentration over time). These participants also had lower heart disease risk, even if they didn't lose weight. The increase in the study participants' activity equaled about 2,200 extra steps a day. The findings were reported in the journal Diabetes Care.

An earlier study found that healthy lifestyle changes may work better than the prescription medication metformin (Glucophage), when it comes to preventing metabolic syndrome. Metabolic syndrome is a combination of risk factors including abdominal obesity, insulin resistance, high triglycerides, and hypertension.

The following are precautions for all people with diabetes, whether type 1 or 2:

Because people with diabetes are at higher than average risk for heart disease, they should always check with their doctors before starting a demanding exercise program. For best and fastest results, frequent high-intensity (not high-impact) exercises are best for people who are cleared by their doctor. For people who have been sedentary, or have other medical problems, lower-intensity exercises are recommended, using programs the patients designed with their doctors.
Strenuous strength training or high-impact exercise is not recommended for people with uncontrolled diabetes. Such exercises can strain weakened blood vessels in the eyes of patients with retinopathy (a common diabetic complication). High-impact exercise may also injure blood vessels in the feet.

Patients who are taking medications that lower blood glucose, particularly insulin, should take special precautions before starting a workout program.

Glucose levels swing dramatically during exercise. People with diabetes should monitor their levels carefully before, during, and after workouts.
Patients should probably avoid exercise if glucose levels are above 300 mg/dL or under 100 mg/dL.
To avoid hypoglycemia (low blood sugar), people with diabetes should inject insulin in sites away from the muscles they use the most during exercise.
People with diabetes should drink plenty of fluids. Before exercising, they should avoid alcohol, which increases the risk of hypoglycemia.
Insulin-dependent athletes may need to decrease insulin doses, or take in more carbohydrates, prior to exercise. However, they may need to take an extra dose of insulin after exercise. Stress hormones released during exercise may increase blood glucose level (in people without diabetes, insulin is released to control this increase). People with diabetes must regularly test their blood sugar, and take any medications as instructed by their doctor.

A person with diabetes must regularly check their blood sugar (glucose) level.

Exercise's Effects on Bones and Muscles

Exercise is critical for strong muscles and bones. Muscle strength declines as people age, but studies report that when people exercise they are stronger and leaner than others in their age group.

Exercise helps kids lower their risk of chronic pain in the future. Research has shown that it helps them prevent back and neck pain. The more flexible men are as teenagers, the lower their risk of neck tension in the future, according to a study published in the February 2006 British Journal of Sports Medicine. The same report found that women who had the greatest endurance strength as teenagers had a lower risk of tension neck than those with lower teenager endurance strength. However, men with the greatest endurance strength had higher rates of knee injuries later on.

Joints are complex structures. They are designed to bear weight and move the body. Above the knee is the femur (thigh bone). Below the knee is the tibia (shin bone) and fibula. The kneecap is also called the patella. It rides on top of the lower portion of the femur and the top portion of the tibia. The muscles and ligaments connect these bones and the space between them is cushioned by fluid-filled capsules (synovia) and cartilage. When you exercise, the muscles pull on the bones, strengthening them. The range of motion of a joint represents how far it can be flexed (bent) and extended (stretched).

Joints require motion to stay healthy. Long periods of inactivity cause the arthritic joint to stiffen and the adjoining tissue to weaken. A moderate exercise program that includes low-impact aerobics, power, and strength training has benefits for osteoarthritic patients, even if exercise does not slow down the disease progression. Many patients who start an exercise program report less disability and pain. They are also better able to perform daily chores, and remain independent longer than their inactive peers. Older patients and those with medical problems should always check with their doctor before starting an exercise program.

The following are useful exercises for osteoarthritis patients:

Strengthening exercises builds muscle strength. Some experts encourage patients to emphasize strengthening leg muscles as a first treatment step, even before using pain relievers. They fear that patients who rely on painkilling drugs may overuse knees, which do not have strong enough muscle tissue to protect the joints from further damage. Strengthening the thigh muscles is certainly protective for those who have not developed osteoarthritis.
Range-of-motion exercises increase the amount of movement in a joint and muscle. The best examples are yoga and tai chi, which focus on flexibility, balance, and proper breathing. In one 2001 study, older adults who practiced the gentle movement, breathing, and meditation exercises of tai chi for 10 weeks reported less pain than their peers who did not learn the technique.
Low-impact aerobic workouts help stabilize and support the joints. Cycling and walking are beneficial, and swimming or exercising in water is highly recommended for people with arthritis. Patients with arthritis should avoid high-impact sports, such as jogging, tennis, and racquetball.
Some researchers are now focusing on "power" training, which involves improving the muscle's ability to move more rapidly against resisting forces, such as gravity. For example, such training helps people stand up or climb stairs more quickly. Muscle power declines more rapidly than muscle strength, and may be particularly important in older people.

Exercise is very important for slowing the progression of osteoporosis, and extremely important for reducing the risk of falling, which causes fractures. Falls are one of the leading causes of death in people over the age of 65. Exercise helps build balance and flexibility, which reduces the risk of falling.

Specific exercises may be especially helpful for reducing the risk of fractures:

Weight-bearing exercise is very beneficial for bones in people of all ages, even older people. This approach applies tension to muscle and bone, and the body responds to this stress by increasing bone density, in young adults by as much as 2 - 8% a year. Careful weight training can also be very beneficial for elderly people, particularly women. In addition to improving bone density, weight-bearing exercise reduces the risk of fractures by improving muscle strength and balance, thus helping to prevent falls.
Regular brisk long walks improve bone density and mobility. In one 2002 study, for example, older women reduced their risk of hip fracture by over 40% by working out just four hours a week.
Exercises specifically targeted to strengthen the back can be beneficial in improving posture, and may even reduce kyphosis (hunchback) in people with osteoporosis.
Low-impact exercises, particularly yoga and tai chi, which improve balance and strength, have been found to decrease the risk of falling. In one study, tai chi reduced this risk by almost half.

Note on Female Athlete Triad. Some young female athletes who exercise very intensely, and are subject to intense pressure to remain thin, are at risk for the female athlete triad. This syndrome is a combination of three disorders -- an eating disorder, loss of menstrual periods, and osteoporosis.

People who do not exercise regularly face an increased risk for low back pain, especially during times when they suddenly have to perform stressful, unfamiliar activities. These activities may include shoveling, digging, or moving heavy items. Although no definitive studies have been done to prove the relationship between lack of exercise and low back pain, sedentary living is probably a primary nonmedical cause contributing to this condition.

Lack of exercise leads to the following conditions that may threaten the back:

Muscle inflexibility can restrict the back's ability to move, rotate, and bend.
Weak stomach muscles can increase the strain on the back and can cause an abnormal tilt of the pelvis (hip bones).
Weak back muscles may increase the load on the spine and the risk of disk compression.
Obesity puts more weight on the spine and increases pressure on the vertebrae and disks. Studies report only a weak association between obesity and low back pain, however.

Benefits for Chronic Back Pain. People in with sudden and severe back pain should not exercise. Exercise plays a very beneficial role in relieving chronic back pain, however. In one study, patients with back pain lasting for an average of 18 months were assigned eight 1-hour exercise sessions over 4 weeks. They showed greater improvement in nearly every area, including reduced pain, compared to patients who did not exercise.

Exercise should be considered as part of a broader program to return to normal home, work, and social activities. In this way, the positive benefits of exercise not only affect strength and flexibility but they also alter and improve the patients' attitudes toward their disability and pain.

Repetition is the key to increasing flexibility, building endurance, and strengthening the specific muscles needed to support the spine. Some exercise programs used for prevention or treatment of chronic low back pain include the following:

Low-impact Aerobic Exercises: Low-impact aerobic exercises, such as swimming, bicycling, and walking, can strengthen muscles in the abdomen and back without over-straining the back. Programs that use strengthening exercises while swimming may be a particularly beneficial approach for many patients with back pain. In one study, for example, pregnant women who engaged in a water gymnastics program had less back pain, and were able to continue working longer.
Lumbar Extension Strength Training: Exercises called lumbar extension strength training are proving to be effective. Generally, these exercises attempt to strengthen the abdomen, and improve lower back mobility, strength, and endurance. They also enhance flexibility in the hip and hamstring muscles, and in the tendons at the back of the thigh.
Yoga, Tai Chi, and Chi Kung: These exercises combine low-impact physical movements and meditation. They are based on principles of disciplining the mind to achieve a physical and mental balance, and can be very helpful in preventing recurrences of low back pain. In one study of Pilates, an exercise practice that uses yoga principles, the exercises were helpful in a woman with progressive and disabling severe low back pain resulting from early scoliosis. This approach deserves further research.
Flexibility Exercises: Whether flexibility exercises alone offer any significant benefit for chronic back pain is uncertain. One study suggested that any benefits derived from flexibility exercises are lost unless the exercise programs are sustained.
Retraining Deep Muscles: Studies are finding a link between low back pain and poor motor control of deep muscles in the back and trunk. According to these studies, contraction exercises specifically designed to retrain these muscles may be effective for patients with both acute and chronic pain.

It is important for any person who has low back pain to have an exercise program guided by professionals who understand the limitations and special needs of back pain and who can address individual health conditions. One study indicated that patients who planned their own exercise did worse than those in physical therapy or doctor-directed programs.

Hazardous Effects on the Back. Improper or excessive exercise can also cause back pain.

Exercise's Effects on the Lungs

Patients with chronic lung problems have difficulty exercising. Shortness of breath is a major limitation in most patients, but in about a third, muscle fatigue is an even greater problem. Although exercise does not improve lung function, training helps many patients with chronic lung disease by strengthening their limb muscles, thus improving endurance and reducing breathlessness.

In people who already have colds, exercise has no effect on the illness' severity or duration. People should avoid strenuous physical activity when they have fevers, muscle aches, or other symptoms of a widespread viral illnesses.

Long-term exercise may help control asthma and reduce hospitalization. One 2000 study found that aerobic exercise improves breathing capacity and function in patients with mild asthma. People with asthma who enjoy running should probably choose an indoor track, to avoid pollutants. Swimming is particularly excellent for people with asthma. Yoga practice, which uses both stretching, breathing, chest expansion, and meditation techniques may have specific benefits that include stress reduction as well as airway opening. One study reported that two thirds of patients who practiced yoga regularly were able to reduce or eliminate their asthma medications.

Exercise-Induced Asthma. About 40 - 90% of asthma cases are exercise-induced asthma (EIA), in which exercise triggers coughing, wheezing, or shortness of breath. It occurs most often in children and young adults and during intense exercise in cold dry air. EIA is triggered only by exercise. Unlike allergic asthma, there is no long-term increase in airway activity. People who only have EIA do not require long-term maintenance therapy. The warm-up and cool-down periods, which are important for any exercise regimen, may help reduce EIA events. A study of military recruits found that exercise-induced asthma attacks did not hinder their ability to perform or train, suggesting that EIA is not a reason to exclude people from physically demanding occupations.

Exercise-induced asthma is distinct from allergic asthma in that it does not produce long-term increase in airway activity. People who only experience asthma when they exercise may be able to control their symptoms with preventive measures such as warm-up and cool-down exercises.

Walking is the best exercise for people with emphysema. Patients should try to walk three to four times daily for 5 - 15 minutes each time. Devices that assist ventilation may reduce breathlessness that occurs during exercise.

Inspiratory muscle training involves exercises and devices that make inhaling (breathing in) more difficult, in order to strengthen breathing muscles. In a 2001 study, patients who took part in an inspiratory muscle training group improved their breathing, walking capacity, and quality of life. Yoga or martial arts exercises, such as tai chi, which emphasize breathing techniques and balanced movements, may be particularly beneficial for patients with emphysema.

Exercise's Effects on Weight

Exercising helps people reduce their weight, maintain weight loss, and fight obesity. Research has shown that women who regularly exercise but do not change their diet can lose significantly more weight than less active women.

Thirty minutes of moderate-intensity exercise may be adequate to maintain cardiovascular health, but it might not prevent weight gain. Recommendations published in 2003 and 2004 suggest that 45 - 60 minutes of exercise per day is necessary to promote weight loss. Children may need more activity.

Losing significant weight requires both exercise and calorie restriction. In addition, if a person exercises without dieting, any actual weight loss may be minimal because dense and heavier muscle mass replaces fat. Nonetheless, regardless of weight loss, a fit body will look more toned and be healthier.

People who exercise are more apt to stay on a diet plan. Exercise improves psychological well-being and replaces sedentary habits that usually lead to snacking. Exercise may even act as a mild appetite suppressant.

Exercising without dieting still adds health benefits. One study found that overweight but fit people have half the death rate of overweight, unfit people. Research suggests that people who have trained for a long time develop more efficient mechanisms for burning fat and are able to stay leaner.

Lifting weights builds muscle, which burns calories more efficiently than other body tissues.

The following are some suggestions and observations on exercise and weight loss:

The treadmill burns the most calories of standard aerobic machines. It may be particularly effective when used in short multiple bouts during the day. Exercise sessions as short as 10 minutes, which are done frequently (about four times a day), may be the most successful program for obese people.
The more strenuous the exercise, the longer the body continues to burn calories before returning to its resting level. This state of fast calorie burning can last for as little as a few minutes after light exercise, to as long as several hours after prolonged or heavy exercise.
Resistance (strength) training is excellent for replacing fat with muscles. It should be performed two or three times a week.
Fidgeting may be very helpful in keeping pounds off. Regular exercise is certainly the best course, but for people who must sit for hours at work, frequently shifting positions while sitting may have some benefit.
It is important to realize that as people slim down, they burn fewer calories per mile of walking or jogging. The rate of weight loss slows down, sometimes discouragingly so, after an initial dramatic head start using diet and exercise combinations. People should be aware of this trend and keep adding to their daily exercise routine.
Changes in fat and muscle distribution may differ between men and women as they exercise. Men tend to lose abdominal fat (which lowers their risk for heart disease faster than reducing general body fat). Exercise, however, does not appear to have the same effect on weight distribution in women. A study of women who practiced aerobic and strength training showed the training resulted in fat loss in the women's arms and trunk. However, they did not gain muscle tissue in those areas.

Because obesity is one of the risk factors for heart disease, anyone who is overweight must discuss their exercise program with a physician before starting.

Exercise's Effects on Other Conditions

Physical activity makes you healthier. It lowers your risk for cardiovascular disease and reduces bone loss. Physical activity also helps the body use calories more efficiently, which helps you eliminate body fat and lose weight. It also helps you maintain weight loss by increasing your metabolism and reducing your appetite.

A number of studies have indicated that regular exercise may reduce the risk of breast, colon, and possibly prostate cancers.

Studies confirm that exercise significantly reduces the risk of both colon cancer (by up to 50%) and breast cancer (by up to 30%).

A 2006 study found that, though protection from breast cancer may vary among the types of tumor, exercise offered the most marked protection from the more aggressive tumors. A second study, also done in 2006, supported this finding. Several studies also suggested that more intense exercise is more protective against breast cancer. Exercising consistently throughout life gives the best protection. Exercise not only lowers a woman's chance of getting breast cancer, it can help those who have received chemotherapy for the disease fight off fatigue.

While endurance athletes may suffer from stomach problems, low intensity exercise has a marked protective effect against colon cancer, according to studies, including the Nurses Health Study and the American Cancer Society's Cancer Prevention Study II. Furthermore, a 2006 study found that people with colon cancer who exercise reduce their risk of a recurrence.

Exercise also has a beneficial effect on people receiving treatment for prostate cancer. A new study found that aerobic and resistance training significantly reduced fatigue in men undergoing radiation treatments for prostate cancer. Fatigue is a common side effect of such treatments. In this study, 122 patients received supervised aerobic training, resistance training, or neither. At the end of 24 weeks, participants in both exercise groups noted significant improvement in their fatigue symptoms, compared to the control group. Participants in the resistance training group also lost a significant percentage of their body fat.

Endurance athletes often report stomach problems, such as bloating, diarrhea, and gas, even at rest. Experts suggest that moderate regular exercise might reduce the risk for some intestinal disorders. These disorders include ulcers, irritable bowel syndrome, indigestion, and diverticulosis. Older people who exercise moderately may have a lower risk for severe gastrointestinal bleeding.

Patients with end-stage kidney disease who exercise four to five times per week have better survival rates than those who are less active, according to researchers involved in the Dialysis Morbidity and Mortality Wave 2 study. However, the majority of study participants said that severe physical limitations prevented them from exercising so often.

Studies have shown that regular exercise, particularly walking, helps reduce one's risk for memory loss. A 2005 study found that older men who walked less than a mile daily had a 71% higher risk of dementia than those who walked more than two miles a day. A 2006 study found that people older than 65 who exercise regularly had lower risk of developing dementia, particularly Alzheimer's disease. An earlier study found that walking regularly protects women from mental decline. To date, there are no clear explanations for this apparent benefit. A preliminary study in mice suggests that physical activity changes the way brain-damaging proteins are processed in the brain, thus slowing the development of Alzheimer's disease. Aerobic exercise has been linked with improved reaction time, perception, and math skills in people of all ages.

Doctors found that exercise improves the physical and emotional well-being of patients who already have Alzheimer's disease. The patients exercised moderately for as little as 60 minutes each week. Doctors noted patients who exercised were less depressed, wandered away less, suffered fewer falls, and were placed in nursing homes later, compared to patients who did not exercise.

People with existing neurological diseases, such as multiple sclerosis, Parkinson's disease, and Alzheimer's disease, should be encouraged to exercise. Specialized exercise programs that improve mobility are particularly valuable for patients with Parkinson's disease. Patients with neurological disorders who exercise experience less stiffness, as well as reduction in, and even reversal of, muscle wasting. In addition, the psychological benefits of exercise are extremely important in managing these disorders. Exercise machines, aquatic exercises, and walking are particularly useful.

Some research has suggested that exercise may have antidepressant effects. Although there is little strong evidence that exercise can help manage depression, a number of studies have suggested benefits. Research findings include:

Just 30 minutes of brisk exercise three times a week was as effective as medication in relieving symptoms, and reducing relapse, in many patients with mild-to-moderate depression.
Over half of older women with depression that did not respond to medication improved with 10 weeks of exercise. (About a third of women who did not exercise also improved during that time.)
Studies on elderly, depressed patients report modest benefits from exercise, even in those who do not response to antidepressants. Simply participating in a group activity may help improve mood.
Teenagers who are active in sports have a greater sense of well-being than their sedentary peers. The more vigorously they exercise, the better their emotional health.
Physical inactivity is strongly linked to depression in children 8 - 12 years of age.

Specific exercises may be particularly beneficial:

Aerobics. Either brief periods of intense training or prolonged aerobic workouts can raise levels of certain chemicals in the brain. These chemicals -- which include endorphins, adrenaline, serotonin, and dopamine -- produce the so-called runner's high. Weight loss and increased muscle tone can boost self-esteem.

Yoga. Yoga practice, which involves rhythmic stretching movements and breathing, has been found to positively affect mood. It may have clinical potential as a technique for improving and stabilizing mood. A study comparing yoga to aerobic exercise found that men have significantly lower levels of tension, fatigue, and anger after yoga, compared with levels after swimming. Yoga and swimming tended to produce equal benefits in women.

Moderate exercise in healthy pregnant women does not increase the risk for miscarriage, preterm labor, or rupture of the membrane. Not exercising increases the risk for complications, including low-birth weight babies. Exercising increases the fetal heart rate, which in turn protects the baby.

Healthy women with normal pregnancies should exercise at least three times a week, being careful to warm up, cool down, and drink plenty of liquids. Many prenatal calisthenics programs are available.

The following are specific exercises that may benefit the pregnant woman:

Swimming and water aerobics may be the best option for most pregnant women. Swimming has special benefits for those with fluid buildup. Water exercises involve no impact, overheating is unlikely, and swimming face down promotes optimum blood flow to the uterus.
Performing yoga exercises under the guidance of informed instructors can be very helpful.
Walking is also beneficial.

To strengthen pelvic muscles, women should perform Kegel exercises at least six times a day. This involves contracting the muscles around the vagina and urethra for three seconds 12 - 15 times in a row.

Experts generally recommend the following precautions for pregnant women who exercise:

Fit women who have exercised regularly before pregnancy may work out intensely as long as the doctor approves and no discomfort occurs.
As a rule for previously sedentary, low-risk expectant mothers, the pulse rate should not exceed 70 - 75% of the maximum heart rate, or more than 150 beats per minute. Any sedentary expectant mother should check with her doctor before starting an exercise program.
According to one study, vigorous exercise may improve the chances for a timely delivery. All pregnant women, however, should avoid high-impact, jerky, and jarring exercises, such as aerobic dancing, which can weaken the pelvic floor muscles that support the uterus.
During exercise, women should monitor their temperature to avoid overheating, a side effect that can damage the fetus. (Pregnant women should also not use hot tubs or steam baths, which can cause fetal damage and miscarriage.)

Note: Strenuous exercise may affect the flavor of breast milk for a short time afterward. Nursing mothers who engage in such activity might want to wait about an hour after exercising before they feed their infant.

Complications

Exercise may lead to injury if not done properly. Always exercise with care.

Competitive running or high-impact aerobics pose a high risk of a number of injuries to the bones and muscle. The effect of high-impact exercise on the back is not entirely clear. Some research suggests that over time, high-impact exercise may increase the risk for degenerative disk disease. A survey of people who played tennis, however, found no increased risk for low back pain or sciatica.

High-impact exercise can also cause dizziness, ringing in the ear, motion sickness, or loss of high-frequency hearing.

Some research further suggests that in people unused to exercise, intense activity increases production of harmful particles in the body called free radicals. These unstable oxygen particles injure muscle tissue. Muscle pain in this case does not occur until 24 - 48 hours after exercise.

Some people have a higher than average risk for injury:

About half of people at any age who participate in competitive running or high-impact aerobics experience minor injuries at least once a year. Young, intensely competitive athletes may be at risk for permanent injury. Studies are mixed over whether intensive high-impact sports in younger people cause long-term degenerative joint disease.
As the number of older people who start exercising increases, there has also been an increase in injuries for this age group. Between 1990 and 1996, injuries from active sports increased by 54% in people age 65 and older.
Women are far more likely than men to suffer knee injuries.
Urinary incontinence affects many female athletes who engage in high-impact exercise.
Tennis players are at high risk for injuries from repetitive force on the shoulder joint.

Preventing High-Impact Injuries. The following may be helpful for preventing injury:

Wear shock-absorbing footwear with weight-dampening inserts.
Combine weight lifting with jumping exercises. This may prevent injury by strengthening hamstrings and improving coordination.
Vary training and alternate easy and harder workouts.
Be careful to warm up, cool down, and stretch. Flexibility is the key to preventing many muscle strains.
Take days off now and then. The risk of injury increases when athletes train more than five times a week.

Because of the association between high-impact exercises and oxidation, some experts suggest eating foods rich in antioxidants, such as vitamins A, C, and E. Such foods, which may protect against damage from free radicals, include many fresh fruits and vegetables.

Treating Minor Injuries. Most mild or moderate injuries respond well to a simple, four-step treatment: rest, ice, compression, and elevation (RICE). This combination works well for both spot injuries and chronic problems. Ice packs, which reduce inflammation and pain, can help new injuries, and can be useful for the first few hours after a chronically injured area is exercised. How much or how long to compress the injury is unclear.

Evidence suggests that early movement is helpful, although taping or bracing in people with a recurrent ankle sprain is known to be protective. It may not be helpful in those without a previous ankle injury.

Minor injuries like sprains may be treated at home if broken bones are not suspected. The acronym RICE can help you remember how to treat minor injuries: "R" stands for rest, "I" is for ice, "C" is for compression, and "E" is for elevation. Pain and swelling should decrease within 48 hours. Gentle movement may help, but pressure should not be put on a sprained joint until pain is completely gone. This can take up to a few weeks.

Heat, ultrasound, whirlpool, and massage may speed healing if applied a day or two after the initial injury or for warm-up before another workout session.

Some young female athletes who exercise very intensely, and are subject to intense pressure to remain thin, are at risk for a syndrome known as the female athlete triad. This combination of symptoms includes loss of menstruation, eating disorders, and osteoporosis. Eating disorders among young female athletes are estimated at 15 - 62%. Women at higher risk include ballet dancers, gymnasts, and divers. Continued intense exercise causes a stress response in which estrogen (the primary female hormone) is lost. Estrogen loss can lead to infertility and osteoporosis. Iron loss and anemia may also be a problem in women who exercise frequently, even at moderate intensity. A doctor should be consulted for any of these concerns.

Incorrect movements can literally cause mechanical problems in the muscles. These problems are usually the result of improper exercise instruction, and lack of attention. A single jerky golf swing, or the incorrect use of exercise equipment (especially free weights, nautilus, and rowing machines), can cause serious back injuries.

Between 30 - 70% of cyclists experience low back pain. Pain may be improved by adjusting the angle of the bicycle seat.

Everyone should drink lots of fluid during intense exercise. Thirst is often a poor indicator of dehydration in people who exercise, particularly older people. During a tough workout in a hot environment, the body can lose two liters of fluid per hour through sweat.

Anyone who exercises intensely should take the following precautions:

Drink 6 - 8 ounces of fluid about 15 minutes before a workout, and then pause regularly during exercise to drink more.
Water is the best choice for replenishing body fluids. Glucose-sodium-potassium solutions, the so-called "sports drinks," which promise instant energy, appear to be no better than water at improving endurance during prolonged intense running.
Caffeinated beverages like coffee and soft drinks give short bursts of energy, but can actually cause fluid loss. Caffeine before a workout has been shown to temporarily raise blood pressure, and reduces blood flow to inactive limbs.

Contrary to popular belief, drinking fluids will not cause cramps. Drinking enough, in fact, helps prevent the painful involuntary muscle spasms that sometimes occur during exercise.

Overheating, or hyperthermia, can be a problem with hard exercise, or when working out in hot weather. Overheating can cause mild to life-threatening conditions. Heat exhaustion, a moderate form of hyperthermia, is characterized by the following symptoms:

Lightheadedness, nausea, headache, hyperventilation, fatigue, and loss of concentration
A high temperature (above 103° F), possibly accompanied by complaints of chills and clammy skin

Individuals should rest in a cool, dry place, drink plenty of fluids, and bring down their body temperature with ice packs pressed against the skin.

Heatstroke. Heatstroke is the most dangerous complication of hyperthermia. The victim may suddenly stop sweating, after which symptoms such as altered consciousness, seizures, and even coma may quickly follow. Heat stroke is a medical emergency and requires immediate cooling of the victim in an ice-water bath or with ice packs. One study suggests that risk for serious complications from exercising in high temperatures may persist as late as the following day, even if the weather has cooled down.

Click the icon to see an image of the dangers of heatstroke.

Precautions are also necessary in cold weather. When exercising in winter dress in layers, including gloves and socks, which create insulated air pockets that trap heat. In cold weather, wear shoes with less ventilation than those worn in the summer. Fingers, toes, ears, and nose are most susceptible to frostbite. Frostbite progresses from stinging or aching to numbness. Fingers and toes may become white. Soaking the hands and feet in warm water can help, but only once there is no risk of refreezing, since a second bout of frostbite after thawing can quicken tissue damage.

Hypothermia can be life-threatening and can occur even after long exposure to temperatures that are above freezing. The condition is characterized by extreme fatigue, mental confusion, apathy, and a lack of coordination. The victim should be warmed as soon as possible with blankets, body heat, and warm fluids.

Motivation

Motivation, or a lack thereof, is one reason many people stop exercising. Here are some tips for avoiding burnout:

Think of exercise as a menu rather than a diet. Choose a number of different physical activities that are personally enjoyable such as sports, dancing, or biking. Although experts say you should get 30 minutes of aerobic exercises at least five times a week, those times can be divided into shorter periods -- such as 10 minute sessions. In addition, people can achieve health benefits from other exercise programs, including weight training, yoga, or tai chi.
Stick to a prepared schedule and record progress.
Develop an interest or hobby that requires physical activity.
Adopt simple routines such as climbing the stairs instead of taking the elevator, walking instead of driving to the local newsstand, or canoeing instead of zooming along in a powerboat.
Try cross training (regularly switching from one type of exercise to another). Studies suggest it is more beneficial than focusing only on one form of exercise.
Exercise with friends.
Join a gym or take classes. Many affordable programs are available.
For those who can afford them, personal trainers can be very helpful and are available in many gyms and exercise clubs. Personal trainers without any connection to a well-reputed gym or fitness club should be certified by a major fitness organization, such as the Aerobics and Fitness Association of America (AFAA) or the American Council on Exercise.
Exercise videos may also be helpful, but people should be sure they are suited to their individual age and health needs, and bear the seal of the AFAA.
Consider getting a dog. A study in the February 2006 American Journal of Preventive Medicine found that dog owners in Canada walk almost twice as much as those who don’t own a dog. Regular walking is a good way to improve health.

Differences in Motivation Between Men and Women. Motivation factors may differ by gender, and women appear to have a harder time. In one study, weight loss was the greatest motivator to exercise for women, and muscle tone was the primary motivator for men. Unfortunately, effects on appearances may take a long time to show, discouraging people from continuing an exercise program even though their health is improving.

Overweight among children and adolescents has now become an epidemic in the United States. Experts say that children should be vigorously active for at least 20 - 60 minutes 3 - 5 days a week. Parents and schools must be imaginative and rigorous in encouraging children to exercise.

Role of Parents. Parents must make conscious efforts to limit sedentary activities, and to encourage physical ones for their children. This includes monitoring the time children spend on the computer, in front of the TV, or playing video games. Parents should suggest different forms of entertainment. Even children who aren't interested in joining a Little League team may enjoy a round of catch with their parents, walking in the park, or swimming in a local lake.

Role of Schools. Early school physical education programs can make a significant difference and the earlier these routines are learned, the more likely they will be carried forth into a healthy adulthood. Schools should emphasize team cooperation or individual improvement and self-mastery. Studies have shown that people tend to give up more quickly and feel less competent if their perceptions of success are based only on comparison to their peers.

People mature at different rates, and there seems to be a genetic component to coordination, strength, speed, and one's response to resistance exercise. Nonetheless, everyone should strive to be as fit as they possibly can, given their strengths and limitations.

The decision to adopt a healthier behavior -- whether it's more exercise, weight loss, or quitting smoking -- is not as simple as just deciding to do it. Behavior change expert James Prochaska and his colleagues outlined a theory, which has been supported by numerous studies, showing that people cycle through a variety of stages before a new behavior is successfully adopted over the long term. It may help you to understand how this works. As you read the description of each stage -- specifically as it relates to exercise -- you may find yourself nodding and saying to yourself, "Yes, that's me!"

Stage 1: Pre-Contemplation. People at this stage have no plans or desire to exercise. They aren't even considering exercising. They are generally unaware of the specific benefits that exercise can bring -- exercise may seem more like a hassle than something worth doing. Or, they may simply have "failed" in the past and have given up.

There's no point in talking about how to start an exercise program if you are at this stage. Instead, it is important to think about how exercise might be good for you personally -- by helping you to lose weight, feel better, have more confidence, live longer, sleep better, or reduce your stress levels. The benefits must be identified before a person will consider exercise.

If you are at this stage, a good activity is to ask four friends or family members why they exercise. Their answers may show you some real-life benefits, and inspire enough interest to compel you to take the next step.

Stage 2: Contemplation. A person at this stage is thinking, "I think I should probably exercise, but I need help getting started." People at this stage know that exercise is good for them, but it seems like a daunting task or they don't think they can pull it off. Some may have tried and "failed" in the past, but they are still receptive to another go-round.

It's important for people at this stage to consider some of the truths and falsehoods of exercise. For example, it is helpful to know that there are many forms of physical activity to select from, and that you can do your exercising in small chunks. It is not true that exercise has to be painful, or that you either succeed or fail. There is no such thing as "failure" -- people become more or less active at different stages of their lives, and it is never too late to get moving again. And people at this stage should find assurance that an exercise plan can be very simple.

If you are at this stage, a good activity is to write down all the things that you believe make exercise difficult -- and to learn strategies for overcoming or side-stepping those hurdles. People at this stage might benefit from making a pledge, contract, or other commitment that they are going to get more active in the near future. The goal is to get un-stuck by identifying the roadblocks and the ways to overcome these roadblocks. The final goal at this stage is to make a commitment.

Stage 3: Preparation. These folks are primed and motivated. They are ready to give exercise a try. The goal of this stage is to create a specific action plan that takes all factors into account, so that the "launch" is successful. People at this stage need to know how much they should be exercising, their target heart rate, and the types of exercises. They should explore the different kinds of exercises and decide which ones to try.

At this stage, people will evaluate exercise machines and health plans, if that interests them, pick the proper clothing or accessories, and consult a doctor if necessary. They also need to think about how they are going to fit their exercise plans into their daily and weekly schedule.

If you are at this stage, you should also consider some backup plans -- what to do if it rains, or if you don't feel like exercising. That way you are prepared to overcome that hurdle when you encounter it. You should be aware of what to expect realistically at the beginning -- for example, be aware that weight loss takes time, but health benefits begin immediately.

Stage 4: Action! People at this stage have just started exercising. This stage is where the biggest behavior change occurs -- these people have started to exercise but it is not yet a long-term, ingrained habit. This stage requires significant commitment and energy.

If you are at this stage, keep talking to friends and family for inspiration. Review your backup plans. Reward yourself for small achievements. Give yourself notes and reminders to exercise. Having a friend to exercise with can be very helpful as you get through this stage. You want to build and maintain momentum, because exercising gets easier once it is a habit!

Stage 5: Maintenance. The people at this stage have been exercising for at least 6 months. At this point, exercising has started to become a habit. The goal here is to prevent relapse. If you are at this stage, identify ways that you can fine-tune your program. Continue to identify roadblocks and improve your backup plans. Think about what you have found most enjoyable about exercising.

What benefits have you gained? Keep reminding yourself of these perks. If giving yourself a challenge was part of your initial motivation, set new goals and find new challenges. If you risk getting bored with your routine, find ways to vary it. Or maybe you have found a comfortable routine that you enjoy -- if it's working, great! There is no need to change it. You might want to read or learn more about your method of exercising, and develop a deeper level of understanding about it. Soon you'll be a pro!

One point about this theory is that people do not proceed from one stage to another in a simple, step-by-step fashion. They actually cycle or spiral back and forth, so that they may move from stage 1 to 2 to 3, and then back to 2 again. They may stay in maintenance mode for years and then fall back to stage 2. Remember that this is normal -- if you tried exercising in the past and didn't stick with it, don't consider yourself a failure. Just know that it's time to try again!

If the Shoe Fits, Make Sure it Fits The Sport

FitSugar — Mon, 13 Aug 2007 17:15:00 -0700

Shopping for sneakers is never an easy situation. There are tons of shoes available (in all shapes and forms) and sneakers are one pair of shoes that you should not pick based on looks. Just because the shoe fits properly, does not always mean it's going to meet your needs. Function and purpose are what you're looking for in your next pair of sneakers.

Since the high schoolers working at the sports store at the mall don't always seem to know a running shoe from a tennis shoe, here are a few tips from The American Podiatric Medical Association on picking the right shoe:

Basketball-Whether you’re making the perfect pass or finishing off the high-flying dunk, basketball shoes have several features that will help prevent injury.
- A thick, stiff sole gives support while running and landing from jumps.
- High ankle construction supports the ankle during quick changes in direction. A basketball shoe should have the strongest support on either side of the ankle.
Racquetball/Tennis-On the surface, court shoes for tennis and racquetball may look like any other athletic sneaker, but it’s what’s on the inside that makes the difference.
- A court shoe supports both sides of the foot because of all the quick lateral movements and weight shifts in court sports.
- It provides a flexible sole for fast changes of direction.
- It has less shock absorption than a running or basketball shoe.

Need tips on picking running shoes, then read more

Running-The running shoe is perhaps the most personal and intricate of all athletic shoes. Every runner has different needs and there are a multitude of choices out there.
- A running shoe must provide maximum shock absorption to help runners avoid ailments such as shin splints and knee pain.
- The shoe should control the way your heel strikes the ground, so the rest of your foot can fall correctly.
- Know your foot type (high, medium, low arch) so you can get the shoe with the right support for your foot.

There are millions of specialized shoes out there and right now I am loving the Asics Gel-Treadmill sneakers because I have been spending a lot of time on the belt lately.

Winterize Your Running: Studded Sneakers

FitSugar — Thu, 08 Jan 2009 03:30:00 -0800

Icy roads and sidewalks are the Winter runner's nemesis. Slick surfaces translate into slips and falls, which can lead to injuries, so you need sneakers with added traction for slippery situations. Runner's World has created a cool and cheap solution: Screw Shoes. The concept is similar to studded tires for your car; the screws create little ice picks on the bottom of your running shoes. Check out the January issue of the mag, flip to page 50, and marathoner Matt Carpenter will explain how you can transform your favorite trail runners into studded sneakers in minutes with a few sheet metal screws.

Would any of you ever try making these studded sneaks?

Are Expensive Sneaks Worth It?

FitSugar — Fri, 16 Nov 2007 14:30:00 -0800

Picking out sneakers can be really confusing, since there are so many different kinds and they vary in price so much. Performance-wise, are expensive sneakers any better than cheaper ones? A team of Scottish scientists used high tech-methods to find out. They found no difference in comfort or shock absorbency between $80 pairs and ones that were more than $150. The bottom line? Paying more moolah doesn't mean you're getting a better shoe.

When it comes to choosing sneaks:

Choose high-quality running shoes that fit your feet. It's fine to stick with a brand you like if you've had great experiences with them, but if you're new to running and don't yet know what you like, try on a few well-known brands to see which ones fit the best.
Think about your needs. If you know you'll be running on pavement and never in the woods, then you shouldn't buy the gray trail running sneakers just because you think they look cute. Never buy workout sneakers based on looks. An adorable shoe won't help you run any faster.

Want to hear the other tips? The read more

If you're not sure which shoes are best suited for which activity, be sure to go to a running store. The staff will be able to help you pick out the right shoe for your needs.
Bring the socks you wear running when you try on your new sneaks. Then use the store's treadmill, track, or floor to try them out. I'm serious. Run for a couple minutes so you can get a true sense of how they'll feel. They should be snug, but not too tight. Your toes should be able to wiggle a little, but your heel shouldn't be slipping up at all.
Don't fall for space-age technology or impressive marketing. You'll be paying extra for all that and not getting much more when it comes to performance.

Fit's Tips: Just like any shoe, sneakers may need a break-in period. Go for shorter walks and runs at first to get your feet used to your new kicks, and gradually increase to longer workouts.

Start Running on the Right Foot

FitSugar — Tue, 13 Nov 2007 04:00:00 -0800

Did all the coverage of the NYC marathon get you pumped up to run? Let me help you avoid a few common mistakes people make when they decide to make running a part of their lives.

Start with where you are now and take time to build up your strength and endurance. Coach Jenny over at Runner's Word says, "Gradually progressing from running with power walking breaks to continuous running is the single fastest way to progress without injury and with a smile on your face." Who doesn't want to smile while they pant?
Don’t run aimlessly, have a plan. My favorite plan for beginners is the Couch to 5k routine from Cool Running. If that is too much structure for you, you can run until you are tired and walk until you are bored.
Buy yourself some nice sneaks. Running is a very repetitive action and you want to cushion your joints as much as possible, so buy shoes made for running and don’t skimp. Plus, if you lay out the big bucks for shoes won’t you regularly run in them to get your money’s worth out of the shoes?
Have a goal. It is a great idea to have a goal so you are working towards something. Pick something doable and motivating like being able to run continuously for 30 minutes or to run a 5k road race. You can find a race near you at Active.com.
Warm-up and cool-down. If you take care of your body, it will take care of you. Warm-up for 5 minutes with a brisk walk before you start jogging and take 5 minutes to walk briskly to cool-down. Sandwiching your run with a 5 minute warm up and cool down will help prevent injury and keep you out running.

Highlights

Drug Approval

In 2007, the Food and Drug Administration (FDA) approved lisdexamfetamine (Vysvanse), a new stimulant drug for the treatment of attention-deficit/hyperactivity disorder (ADHD). The active ingredient in lisdexamfetamine is similar to dextroamphetamine, the drug used in Dexedrine and Adderall.

Drug Warning

In 2007, the FDA instructed the manufacturers of all ADHD drugs to include drug warning labels describing the risks for heart and psychiatric side effects. Doctors should carefully evaluate patients for any risk factors. Reports have linked ADHD drugs to sudden death in patients with serious heart problems. There is also a slightly increased risk for auditory hallucinations, paranoia, and manic behavior even in patients with no history of psychiatric problems. The FDA warning applies to all stimulant ADHD drugs and to the non-stimulant drug atomoxetine (Strattera).

Ritalin Can Stunt Growth

After 3 years of methylphenidate (Ritalin) treatment, children are about an inch shorter and 6 pounds lighter than their peers who do not take this drug, according to a 2007 study in the Journal of the American Academy of Child and Adolescent Psychiatry.

ADHD Improves Over Time

ADHD symptoms may improve over time regardless of the treatment approach, indicates a 2007 study in the Journal of the American Academy of Child and Adolescent Psychiatry. Researchers found that medication, behavioral therapy, or a combination of the two all helped produce improvement after 3 years. There appeared to be no significant difference between children who took medication and those who did not.

Neurofeedback May Help ADHD

Neurofeedback (also known as biofeedback) is a non-drug treatment that may help improve attention and behavior problems associated with ADHD. This treatment approach involves teaching children to control their brain wave activity.

Introduction

According to the U.S. National Institute of Mental Health, attention deficit hyperactivity disorder (ADHD) is a legitimate psychologic condition.

ADHD is a syndrome generally characterized by the following symptoms:

Inattention
Distractibility
Impulsivity
Hyperactivity

Some experts categorize ADHD into three subtypes:

Behavior marked by hyperactivity and impulsivity, but not inattentiveness
Behavior marked by inattentiveness, but not hyperactivity and impulsivity
A combination of the above two

There is some debate over these criteria. Some argue the condition is over-diagnosed. Others say it's underdiagnosed. (See Difficulties in Identifying Children with ADHD later in this article.) One-third of cases are accompanied by learning disabilities and other neurologic or emotional problems, making an ADHD diagnosis particularly difficult. It is likely that the term attention-deficit hyperactivity disorder will eventually give way to subgroups of problems that include some of these general symptoms.

In the United States, about 4.7 million children ages 3 - 17 have been diagnosed at some point with ADHD. This accounts for 7.4% of all American children in this age range.

ADHD is a genuine disorder, but it is telling that the U.S. accounts for 90% of worldwide prescriptions for stimulants for ADHD. It is not known whether this reflects a real increase in ADHD, or a better ability to recognize it. Some say it may be an indication of a culture that places excessive value on normalcy and academic achievement at the expense of more frequent diagnoses.

Symptoms of ADHD usually occur before the age of 7. Studies indicate that ADHD symptoms in preschool children with ADHD do not differ significantly from older children.

The classic ADHD symptoms do not always adequately describe the child's behavior, nor do they describe what is actually happening in the child's mind. Some experts are focusing on deficits in "executive functions" of the brain to understand and describe all ADHD behaviors. Such impaired executive functions in ADHD children can cause the following problems:

Inability to hold information in short-term memory
Impaired organization and planning skills
Difficulty in establishing and using goals to guide behavior, such as selecting strategies and monitoring tasks
Inability to keep emotions from becoming overpowering
Inability to shift efficiently from one mental activity to another

Hyperactivity. The term hyperactive is often confusing since, for some, it suggests a child racing around non-stop. A boy with ADHD playing a game, for instance, may have the same level of activity as another child without the syndrome. But when a high demand is placed on the ADHD child's attention, his brain motor activity intensifies beyond the levels of the other children. In a busy environment, such as a classroom or a crowded store, ADHD children often become distracted and react by pulling items off the shelves, hitting people, or spinning out of control into erratic, silly, or strange behavior.

Impulsivity and Temper Explosions. Even before the "terrible twos," impulsive behavior is often apparent. The toddler may gleefully make erratic and aggressive gestures, such as hair pulling, pinching, and hitting. Temper tantrums, normal in children after age 2, are usually exaggerated and not necessarily linked to a specific negative event in the life of an ADHD child. One of the most painful events a parent may experience is an abrupt and aggressive attack that may occur after cuddling a young ADHD child. Often this reaction seems to be caused not by anger, but by the child's apparent inability to endure overstimulation or displays of physical affection.

Attention and Concentration. ADHD children are usually distracted and made inattentive by an overstimulating environment (such as a large classroom). They are also inattentive when a situation is low-key or dull. Some experts believe that certain parts of the brain in ADHD children may be underactive, so the children fail to be aroused by nonstimulating activities. In contrast, they may exhibit a kind of "super concentration" to a highly stimulating activity (such as a video game or a highly specific interest). Such children may even become over-attentive -- so absorbed in a project that they cannot modify or change the direction of their attention.

Impaired Short-Term Memory. Many experts now believe that an essential feature in ADHD, as well as in learning disabilities, is an impaired working (also called short-term) memory. People with ADHD can't hold groups of sentences and images in their mind long enough to extract organized thoughts. They are not necessarily inattentive. Instead, a patient with ADHD may be unable to remember a full explanation (such as a homework assignment), or unable to complete processes that require remembering sequences, such as model building. In general, children with ADHD are often attracted to activities (television, computer games, or active individual sports) that do not tax the working memory, or produce distractions. Children with ADHD have no differences in long-term memory compared with other children.

Inability to Manage Time. Studies suggest that children with ADHD have difficulties being on time and planning the correct amount of time to complete tasks. (This may coincide with short-term memory problems.) In one study, although children with probable ADHD were able to self-report many ADHD symptoms, they tended to believe they used their time wisely, in contrast to reports by their teacher.

Lack of Adaptability. ADHD children have a very difficult time adapting to even minor changes in routines, such as getting up in the morning, putting on shoes, eating new foods, or going to bed. Any shift in a situation can precipitate a strong and noisy negative response. Even when they are in a good mood, they may suddenly shift into a tantrum if met with an unexpected change or frustration. In one experiment, ADHD children could closely focus their attention when directly cued to a specific location, but they had difficulty shifting their attention to an alternative location.

Hypersensitivity and Sleep Problems. ADHD children are often hypersensitive to sights, sounds, and touch. They usually complain excessively about stimuli that seem low key or bland to others. Sleeping problems usually occur well after the point when most small children sleep through the night. In one study, 63% of children with ADHD had trouble sleeping.

A. Either 1 or 2 should be present:

1. Should have 6 or more of the following symptoms of inattention, persisting for at least 6 months to a degree that is maladaptive and inconsistent with developmental level:

Often fails to give close attention to detail, makes careless mistakes

Often has difficulty sustaining attention in tasks or play

Often does not seem to listen when spoken to directly

Often does not follow through and fails to finish tasks

Has difficulty organizing tasks and activities

Avoids or dislikes tasks requiring sustained mental effort

Often loses things necessary for tasks or activities

Is often easily distracted by extraneous stimuli

Is often forgetful in daily activities

2. Should have 6 or more of the following symptoms of hyperactivity-impulsivity that lasts for at least 6 months to a degree that is maladaptive and inconsistent with developmental level:

Often fidgets or squirms when sitting

Has difficulty remaining seated when required to do so

Often runs about or climbs excessively in inappropriate situations

Has difficulty playing quietly

Is often "on the go"

Often talks excessively

Often blurts out answers to questions before they have been completed

Has difficulty waiting for his or her turn

Often interrupts or intrudes on others

Note: Patients with A1 symptoms are diagnosed with ADHD, predominantly inattentive type. Those with A2 are diagnosed with ADHD, predominantly hyperactive-impulsive type. Those with both A1 and A2 are diagnosed as ADHD, combined-type.

B. Onset of some symptoms before the age of 7. However, children with the inattentive subtype are not often diagnosed until they are above 7 years of age.

C. Symptoms occur in two or more settings. For example, at home and at school.

D. Clear evidence of significant impairment in social or academic functioning.

E. Not caused by a pervasive developmental disorder, schizophrenia, or any other psychotic disorder, and is not better accounted for by another mental disorder, including anxiety or depression.

Risk Factors

ADHD is most often diagnosed in boys. However, there is some evidence that it is underdiagnosed in girls. Until recently, all major studies were conducted using boys as subjects. Important studies on girls with ADHD are now underway. A major study reported that girls with the condition experience the same multiple impairments as boys do.

Although ADHD is primarily thought of as a childhood disorder, diagnoses of attention-deficit disorder in adults are on the rise. Methylphenidate (Ritalin) was prescribed for nearly 800,000 adults in the U.S. in 1997, nearly three times the number in 1992. As of 2005, experts estimated that ADHD affects about 4.1% of adults ages 18 - 44 years in a given year.

How Is ADHD Identified in Adults?

Research suggests that ADHD affects 2 - 6% of the adult population, assuming that one- to two-thirds of cases persist into adulthood. ADHD in adults always occurs as a continuum of the childhood condition. Adult-onset symptoms are likely due to other factors. Diagnosing adult ADHD can be a difficult problem since hyperactivity typically wanes as children get older, while attention and organizational problems may develop in older people. Some experts believe, then, that the number of adults with ADHD is underestimated.

A rating scale using four factors may be useful in identifying adults with ADHD:

Inattention and memory problems. (Examples: losing or forgetting things, being absent-minded, not finishing things, misjudging time, depending on others for order, having trouble getting started, changing jobs or projects in the middle.)
Hyperactivity and restlessness. (Examples: always being on the go, fidgety, easily bored, taking risks, liking active and fast paced jobs and activities, such as being a sales representative or stockbroker.)
Impulsivity and emotional instability. (Examples: saying things without thinking first, interrupting others, being annoying to others, easily frustrated, easily angered, having unpredictable moods, driving recklessly, having high relationship and job turnover.)
Problems with self worth. (Examples: Avoids new challenges, appears confident to others but not to oneself.)

Doctors use adult reports of their childhood behaviors and experiences when searching for clues for a diagnosis. Interestingly, the disorder seems to be distributed equally between adult women and men.

How Serious Is Attention Deficit Disorder in Adults?

Accompanying Emotional, Personality, and Learning Disorders. Between 19 - 37% of adults with ADHD have depression or bipolar disorder. Between 25 - 50% have an anxiety disorder. Bipolar disorder plus ADHD, in fact, may be very difficult to differentiate from ADHD alone in adults.

Accompanying Learning Disorders. About 20% of adults with ADHD have learning disorders, usually dyslexia and auditory processing problems. These problems should be considered in any treatment plan.

Effect on Work. Compared to adults without ADHD, those with the condition tend to reach lower educational levels, earn less money, and be fired more often. In fact, one article reported that by the time they are in their 30s, about 35% of ADHD adults are self-employed.

Substance Abuse. About 1 in 5 adults with ADHD also contend with substance abuse. Studies indicate that adolescents with ADHD are twice as likely to smoke cigarettes as their peers who do not have ADHD. Cigarette smoking during adolescence is a risk factor for the development of substance abuse in adulthood.

Sleep Disorders. Sleep disorders, especially restless legs syndrome and sleep apnea, are common in adults and children with ADHD. Sleep apnea is a disorder in which a person temporarily stops breathing during sleep, perhaps hundreds of times. In most cases the person is unaware of it, although sometimes they awaken and gasp for breath. It is usually accompanied by snoring. One report suggested that treating sleep apnea in adults with both conditions may help reduce ADHD symptoms. [For more information, see In-Depth Report #65: Sleep apnea.]

Causes

Brain Structures. Research using advanced imaging techniques shows there is a difference in the size of certain parts of the brain in children with ADHD compared to children who do not have ADHD. The areas showing change include the prefrontal cortex, the caudate nucleus and globus pallidus, and the cerebellum:

The prefrontal cortex is located in the front of the brain. It is thought to be the brain's command center. It regulates the brain’s ability to block certain responses. Numerous imaging studies have indicated that the prefrontal cortex of the brain in people with ADHD may be less active than in those without the disorder.
The caudate nucleus and globus pallidus, located near the center of the brain, speed up or stop orders coming from the prefrontal cortex. In some reports, these areas have been smaller than average in young children with ADHD, but tended to become normal as the children got older. Abnormalities in these areas may impair a person's ability to stop certain actions, resulting in the impulsivity typical of people with ADHD.
The cerebellum is the area above the brain stem. This area helps control muscle tone and balance, and synchronizes muscle activity. This has been found to be smaller in children with ADHD compared to those without the condition.

Brain Chemicals. Abnormal activity of certain brain chemicals in the prefrontal cortex may contribute to ADHD. The chemicals dopamine and norepinephrine are of special interest. Dopamine and norepinephrine are neurotransmitters, or chemical messengers, that affect both mental and emotional functioning. They also play a role in the "reward response." This response occurs when a person experiences pleasure in response to certain stimuli (such as food or love). Studies suggest that increased levels of the brain chemicals glutamate, glutamine, and GABA -- collectively called Glx -- interact with the pathways that transport dopamine and norepinephrine.

Nerve Pathways. Another area of interest is a network of nerves called the basal-ganglia thalamocortical pathways. Abnormalities along this neural route have been associated with ADHD, Tourette syndrome, and obsessive-compulsive disorders, all of which share certain symptoms.

Genetic factors may play the most important role in ADHD. The relatives of ADHD children (both boys and girls) have much higher rates of ADHD, antisocial, mood, anxiety, and substance abuse disorders than the families of non-ADHD children. A study reported that 90% of children with a diagnosis of ADHD shared it with their twin.

Genetic Factors Regulating Dopamine and Advantages in Early Man. Most of the research on the underlying genetic mechanisms targets the neurotransmitter dopamine. Variations in genes that regulate specific dopamine receptors have been identified in a high proportion of people with addictions and ADHD. Such genes have been associated with novelty seeking and extroversion. Some experts theorize that the genetic variants may have first appeared thousands of years ago, and affect as many as half of ADHD children. Furthermore, the genetic variations may have offered some benefits to their early carriers. In such people, a genetic predilection for novelty-seeking and risk-taking may have supplied an advantage in reproduction, mating, hunting, and achieving dominance.

Genetic Resistance to Thyroid Hormone. About 50% of adults and 70% of children with a genetic resistance to thyroid hormone, essential for normal brain development, have ADHD. People who have this condition appear to have a more severe form of ADHD. The thyroid disorder is not a common cause of ADHD. Only those with a family history of thyroid disease are at risk.

Infant malnutrition is a strong risk indicator of ADHD. Even if children receive enough food later on, infants who suffer from malnutrition may develop behavior problems, the most prevalent being attention-deficit disorder.

Deficiencies in Zinc and Essential Fatty Acids. Several dietary factors have been researched in association with ADHD, including sensitivities to certain food chemicals, deficiencies in fatty acids (compounds that make up fats and oils) and zinc, and sensitivity to sugar.

Some studies have found an association between deficiencies in certain fatty acids and ADHD. Other research reports an association between zinc deficiencies and ADHD. Zinc aids in the breakdown of fatty acids, which affects dopamine, the neurotransmitter likely to be involved with ADHD.

No clear evidence has emerged, however, that implicates any of these nutritional factors in ADHD.

Research suggests that prenatal exposure to tobacco, alcohol, environmental lead, and other toxins may increase the risk for ADHD and conduct disorders.

Diagnosis

Important factors for making a diagnosis of attention-deficit hyperactivity disorder (ADHD) include:

Children between ages 6 - 12 should first be evaluated for ADHD if they show symptoms of inattention, hyperactivity, impulsivity, academic underachievement, or behavior problems in at least two settings. Such behaviors should have been harmful for the child academically or socially for at least 6 months.
The child should meet the official symptom guidelines.
A diagnosis requires detailed reports by parents or caregivers. It should be noted that a mother's description of her child's behavior is a very accurate and reliable guide for diagnosing ADHD. Parents should not be shy about insisting on further evaluation if their experience does not match a doctor's single observation of their child.
Guidelines for primary care doctors emphasize the importance of obtaining direct evidence from the classroom teacher or other school-based professionals about the child's symptoms and their duration, and evidence of functional impairment in the school setting.
The child should be assessed for accompanying conditions (such as learning difficulties).

No laboratory or imaging tests exist to reliably diagnose ADHD. A diagnosis relies only on behavioral symptoms and ruling out other disorders. Many experts believe that the disorder is both over- and underdiagnosed. Diagnosis of attention-deficit hyperactivity disorder is difficult for some of the following reasons:

Factors Leading to the Over-Diagnosis of ADHD:

The popularity methylphenidate (Ritalin) has encouraged some parents and teachers to pressure doctors into prescribing this standard ADHD drug for children who are aggressive or who have poor grades. Often with careful testing many of these children do not meet the criteria for the illness. Children may have other diagnoses, other behavioral or emotional problems, or no problems at all.
Other factors that may contribute to misdiagnosis include children who are young for their grade and therefore socially and intellectually immature, and social and economic problems such as single parent households.

Factors Leading to the Under-Diagnosis of ADHD:

Some evidence suggests that many girls with ADHD may go underdiagnosed. Research indicates that girls with ADHD are often inattentive but not hyperactive or impulsive. In fact, older girls with ADHD tend to have social problems due to withdrawal and internalized emotions, showing symptoms of anxiety and depression. The inattentive subtype, in any case, may first show up in older children and adolescents.
Doctors may fail to diagnose children with ADHD because they often behave normally in the quiet doctor's office where there are no distractions to trigger symptoms. In addition, doctors may be unfamiliar with how to diagnose the condition.
In spite of the fact that there seems to be no differences in response to treatment among population groups, African-American, Hispanic, and Asian children with ADHD are half as likely to be diagnosed and treated as Caucasian children. By high school, the racial disparity increases to the level that the medication rate for blacks is one-fifth of that for whites.

The doctor will first require a detailed history of the child's behavior. Doctors will match this against a standardized checklist to define the disorder.

The parents should describe the following:

Specific problems, beginning as early as possible, they have encountered during the child's development -- school reports are very helpful
Sibling relationships
Recent life changes
A family history of ADHD
Eating habits
Sleep patterns
Speech and language development
Any problems during the mother's pregnancy or during delivery
Any history of medical or physical problems, particularly allergies, chronic ear infections, and hearing difficulties

The health professional will want to know how the parents handle different situations, and may want to observe them interacting with the child.

The child should also be given a general physical examination to determine if any medical conditions are present. The child should be given a hearing test to rule out hearing abnormalities as a source of behavioral problems.

Various tests are available to test neurologic, intellectual, and emotional development problems. Most involve learning and problem solving tasks that help define the particular areas that are most disabling. Blood or other laboratory tests are currently recommended only if the doctor suspects lead toxicity or other medical problems.

Although some doctors use a trial of a psychostimulant (usually Ritalin) to facilitate diagnosis, most experts strongly recommend against this method of diagnosis, because it is not always accurate. An improvement in symptoms is considered suggestive of ADHD, while in non-ADHD children the stimulant often increases agitation and hyperactivity. Many children and adults without the disorder have a similar response, and such a diagnostic trial may lead to unnecessary prescriptions of this drug.

Other Disorders Associated with ADHD

Several disorders may mimic or accompany attention-deficit disorder. ADHD exists alone in only about one-third of children. Many professionals object to the use of the single term "attention-deficit hyperactivity disorder" to encompass such a wide spectrum of behaviors, which they believe should be categorized into subgroups. Many of these problems require other modes of treatment and should be diagnosed separately, even if they accompany ADHD.

Attention-deficit disorder can appear without hyperactivity, in which case the child's primary symptoms are distractibility and an inability to persist in tasks.

About 14% of children diagnosed with ADHD also have oppositional-defiant disorder (ODD). The most common symptom for this disorder is a pattern of negative, defiant, and hostile behavior toward authority figures that lasts more than 6 months. In addition to displaying inattentive and impulsive behavior, these children demonstrate aggression, have frequent temper tantrums, and display antisocial behavior. A significant number of children with ODD also have anxiety disorders and depression, which should be treated separately. Many children who develop ODD at an early age go on to develop conduct disorder.

Some children with ADHD also have conduct disorder, which describes a complex group of behavioral and emotional disturbances seen in children. It includes aggression towards people and animals, destruction of property, deceitfulness, lying, or stealing, and general violation of rules.

Pervasive developmental disorder (PDD) is rare and usually marked by autistic-type behavior, hand-flapping, repetitive statements, slow social development, and speech and motor problems. If a child who has been diagnosed with ADHD does not respond to treatment, the parents might inquire about PDD, which often responds to antidepressants. Some children with PDD may also benefit from stimulants.

Children with ADHD often have difficulties with tasks that involve listening or hearing. Research is indicating that symptoms of the two disorders often overlap but may actually be two distinct disorders. Hearing problems themselves may cause ADHD symptoms.

Children diagnosed with attention-deficit disorder may also have bipolar disorder, commonly called manic depression. Indications of this problem include episodes of depression and mania (with symptoms of irritability, rapid speech, and disconnected thoughts), sometimes occurring at the same time. [For more information, see In-Depth Report #66: Bipolar disorder.] Both disorders often cause inattention and distractibility and may be difficult to distinguish, particularly in children. Children with mania and ADHD may have more aggression, behavioral problems, and emotional disorders than those with ADHD alone. In some cases, ADHD in children or adolescents can even be a marker for an emerging bipolar disorder. The primary way to differentiate bipolar disorder from ADHD is by the presence of a manic or hypomanic episode, which occurs in patients with bipolar disorder but not with ADHD. Most children with bipolar will also respond to the drug valproate, which does not typically work for ADHD in children.

Anxiety disorders commonly accompany ADHD. Obsessive-compulsive disorder is a specific anxiety disorder that shares many characteristics with ADHD and may share a genetic component. Young children who have experienced traumatic events, including sexual or physical abuse or neglect, exhibit characteristics of ADHD, including impulsivity, emotional outbursts, and oppositional behavior.

Sleep disorders or disturbances are very common with ADHD patients. Insomnia is common. In addition, specific sleep disorders -- restless legs syndrome and sleep-disordered breathing -- have been identified with hyperactivity and conduct disorder.

Restless Legs Syndrome (RLS). Some experts believe RLS and periodic limb movement disorder are strongly associated with ADHD in some children. One theory is that the two are linked by a common mechanism. The disorders have much in common, including poor sleep habits, twitching, and the need to get up suddenly and walk about frequently. They may even be genetically linked. For example, both have been associated with lower levels of dopamine in the brain, which is associated with faulty motor control, a common problem in both disorders.

Sleep-Disorder Breathing and Sleep Apnea. Some research has shown an association between mild symptoms of ADHD and sleep-disordered breathing, including snoring and obstructive sleep apnea in children and adults. Treating the sleep-related breathing disorders may improve the attention disorder in some children. (One study indicated that such problems are unlikely to be associated with children with moderate to severe ADHD.) [For more information, see In-Depth Report #65: Sleep apnea.]

Tourette Syndrome and Other Genetic Disorders. Several genetic disorders cause symptoms resembling ADHD, including fragile X and Tourette syndrome. About 50% of those with Tourette syndrome also have ADHD, and some of the treatments are similar.

Other Medical Conditions. A number of medical conditions, including hyperthyroidism and vision problems, can produce ADHD-like symptoms.

Lead. Children who ingest even low amounts of lead may manifest symptoms similar to those of ADHD. A child may be easily distractible, disorganized, and have trouble thinking logically. The major cause of lead toxicity is exposure to leaded paint, particularly in homes that are old and in poor repair.

Complications

More than half of children with attention-deficit disorder have accompanying disorders, including anxiety, depression, and conduct disorders. Children with ADHD who experience anxiety or depression are also more likely to suffer from low self-esteem.

Anti-Social Behavior. Even if these emotional disorders are absent in childhood, the ADHD child's relationship with others is volatile, and they are often unhappy from a very young age. Research indicates that any boy or girl with ADHD, particularly an aggressive child, has trouble getting along with others, and is less liked by his or her peers.

Children with the inattentive subtype of ADHD are more likely to be picked on and to spend time alone.
Children with the combined subtypes tend to have different problems. Boys with ADHD are less likely than others to empathize with people in difficult circumstances. A best friend can turn into an enemy overnight when, for example, a boy with ADHD does not perceive his friend's fearful response to over-aggressive roughhousing and fails to let up. The next day the child with ADHD has forgotten the event; the ex-friend hasn't. When a child with ADHD hurts someone, the child either may go into a state of denial or blame himself excessively. As ostracism, fear, and ridicule from peers persist from year to year, the unstable behavior, originally neurologic, becomes emotionally based. Unless this cycle is broken, serious adult problems can evolve.

Substance Abuse in Young People. Studies consistently report that young people with ADHD -- in particular those with conduct or mood disorders -- have a higher than average risk for substance abuse and that it starts in younger ages. In one study, for example, by age 11 nearly 20% of children with ADHD had tried smoking cigarettes, drinking alcohol, or both. Biologic factors associated with ADHD may make these individuals susceptible to substance abuse. Many of these young people are self-medicating their condition. In fact, according to a major analysis, Ritalin or other stimulants used to treat ADHD may help protect such patients against substance abuse. (Boys with ADHD and conduct disorder, however, still face a high risk for substance abuse. Girls with ADHD and emotional disorders may also still have a higher risk.)

High-Risk Behavior. Impulsivity in young people with ADHD can certainly cause them to take chances before thinking them through, putting them in situations where the consequences become clear only after the action has been taken. Children with ADHD and high levels of aggression are at higher risk for delinquent behavior in adolescents and criminal activity in adulthood. However, children with ADHD who are not aggressive have a lower and even normal risk for dangerous activities. Even in aggressive children with ADHD, close parental attention and early treatment can limit the risk considerably.

Although speech and learning disorders are common in children with ADHD, the disorder does not affect intelligence. People with ADHD span the same IQ range as the general population.

Many children with ADHD are underachievers, and half are held back in school at least once. Some evidence suggests that inattention may be a major factor in low academic performance in these children. About 20% also have reading difficulties, and 60% have serious handwriting problems. Adults with ADHD are also at very high risk for these conditions.

Some research suggests that ADHD persists in one- to two-thirds of those diagnosed with the condition in childhood. Many researchers describe the pattern of ADHD as they would a chronic illness, with remission and periods of worsening.

The time and attention needed to deal with a child with ADHD can change internal family relationships and have devastating effects on parents and siblings.

Effect on Parents. Studies indicate that any intervention for the child must include the parents. Parents who are responsive to their child in a positive way can help reduce the chances for oppositional behaviors. But it can be very difficult. A child with ADHD is wonderful one day and terrible the next, for no apparent reason. The parent can feel betrayed and hurt, and believe they have no control over their child. Parents must protect themselves and their child by establishing tough but kind rules about where their space ends and the child's begins. The are many effects on parents:

Mothers generally get the brunt of the emotional and physical abuse that a child with ADHD can produce.
Parents may have to give up on the idea of an immaculate house and a hot meal every night. Parents must learn that striving for perfection is among the most counterproductive goals to pursue in raising a child with ADHD, or any child.
Parents must face the hostility and anger of other parents and see their own child rejected. It is very easy to fall into an emotional black hole, and feel alone, inadequate, and helpless.
Marriages are often stressed to the breaking point because of exhaustion and disagreements between the husband and wife on how to respond to the child.

Effect on Siblings. Siblings of children with ADHD have particular difficulties, and are also at risk for psychologic impairment, depression, drug abuse, and language disorders. The non-ADHD sibling does not have the control a parent does in the management of the ADHD child's behavior and is very likely to feel alienated and alone. Children without ADHD are often victimized by siblings with ADHD who may be demanding or bullying.

A sibling who does not receive attention in their own right may begin to imitate undesirable behaviors or to act out negatively in other ways. It is very important to make the brothers and sisters equally vital to the family's functioning. However, they should never be made to feel that their value in the family is as caregivers of the ADHD sibling.

Treatment

A combination of a psychostimulant, most commonly methylphenidate (Ritalin), and cognitive-behavioral therapy is proving to be the best option for treatment of children with ADHD. Although medication can be helpful during the initial years of treatment, some research indicates that the benefits of medication eventually wear off. It appears that for ADHD symptoms may improve naturally over time, regardless of the treatment approach.

Signs that ADHD may be easing include not having to adjust medication dosages during growth spurts, no deterioration when a drug dose is missed, or new abilities to concentrate during “drug holidays.” (School vacation times are a good period to test the effectiveness of temporarily stopping medication.) The American Academy of Child and Adolescent Psychiatry suggests that parents evaluate whether medication can safely be withdrawn when children with ADHD have been free of symptoms for at least 1 year. If a child’s condition worsens after medication withdrawal, the drug should be resumed.

Developing a Treatment Approach. The following guidelines may be useful in determining a treatment approach for children with ADHD:

Behavioral techniques, possibly including dietary changes, should be tried first, if possible.
If the symptoms are severe or do not respond, a trial using medication (usually psychostimulants), in conjunction with behavior modification therapy, is advisable.

Cognitive behavioral therapy (CBT) is often administered by mental health providers, with both primary care physicians and psychiatrists prescribing medications. Unfortunately, many children do not have access to behavioral therapies, either because of lack of time or available resources.

Specific Patient Populations. Unfortunately, such guidelines do not address the following specific patient groups:

There are no definite guidelines for treating preschool children with severe ADHD. Some parents have reported very good long-term results with behavioral interventions at this age.
There are no reliable guidelines on how to treat the inattentive subtype of ADHD, which might be more common in girls.
There are no defined treatments for ADHD patients with accompanying conditions, including impaired working memory and deficits in language processing.
There are no defined treatments for children with ADHD and accompanying emotional problems, such as bipolar or anxiety disorders. (There is some evidence, for example, that children with ADHD plus anxiety disorders do worse on psychostimulants.)

Determining a Medication Regimen. Doctors still have a difficult time predicting which medications will produce beneficial results, so treatment is individualized and performed on a trial and error basis, which requires close observation and cooperation between all participants. In developing an effective medication plan, the following steps may be helpful:

Before any drug is administered, a child should be given a thorough examination for any medical problems to be sure there are no medical conditions that interfere with the medication.
Both the doctor and the parents should be very clear about the specific behaviors they hope the medication will target.
The goal is to use the lowest possible dosage that produces improved behavior.
If an initial regimen doesn't work, changing the dosage, or changing to a different medication often brings improvement.
Frequent follow-up visits should be scheduled to assess the response and to detect possible side effects.

Arguments For and Against Psychostimulants. Many parents are very disturbed by the idea of putting their children on intensive stimulant drug regimens, possibly for years, particularly given the uncertainties in diagnosis and the negative publicity surrounding the use of these drugs. Although the decision to use these drugs should not be made lightly, the negative social and emotional effects of the disorder itself for many children with ADHD are far more severe and long-lasting than the use of these drugs. For some parents and children, medication seems like a miracle and can provide desperate families with a quality of life for which they had almost given up hope. Whether or not psychostimulants are used, children and families should understand that ongoing efforts around behavior control will be necessary.

Of great concern is the dramatic increase in prescriptions for psychostimulants among preschool children. Although low doses of methylphenidate (Ritalin) may help preschoolers (ages 3 - 5 years) with ADHD, the drug can cause considerable side effects in many children. These side effects include insomnia, nervousness, anxiety, loss of appetite and weight, and slowed growth. Children in one large study grew about an inch less and weighed about 6 pounds less than normal after 3 years of methylphenidate treatment. Doctors must carefully consider the risks versus benefits when prescribing ADHD drugs to preschoolers. Children who do receive these drugs need to be carefully monitored by their doctors.

Treatment for Adult ADHD. As with children, adults with ADHD are treated with a combination of medication and psychotherapy. For medication, stimulant drugs or the non-stimulant drug atomoxetine (Strattera) are usually first-line treatments, with antidepressants a secondary option. Atomoxetine is approved specifically for adults with ADHD. Adults who have heart problems or heart condition risk factors should be aware of the cardiovascular risks associated with ADHD medication. There have been ADHD medication-associated incidents of sudden death in patients with underlying serious heart problems, and reports of stroke and heart attack in adults with cardiac risk factors.

Research increasingly supports the view that interventions for the ADHD child must also include the parents if they are to be successful. Teachers and school officials should also be educated and involved in the process.

Parents who feel they have the most control over their child's situation experience the least psychological stress and depression. Parents who are responsive in a positive way also help reduce the chances for their child developing oppositional behaviors. But it can be very difficult, particularly for parents who have ADHD themselves. In fact, parents who have severe ADHD symptoms are less likely to respond to parent training programs unless they get help for themselves.

In addition to behavioral therapy for the child, family therapy may help ADHD children and their parents and siblings cope with the emotional conflicts that nearly always arise in the lifelong process of managing the condition. Separate psychological therapies for specific family members might be needed, particularly in light of the high incidence of psychiatric and other emotional problems in families with ADHD children.

Medications

Several types of medication are available to treat ADHD.

Psychostimulants are the primary drugs used to treat ADHD. Although these drugs stimulate the central nervous system, they have a calming effect on people with ADHD.

These drugs include:

Methylphenidate (Ritalin, Concerta, Metadate, Daytrana)
Dexmethylphenidate (Focalin)
Amphetamine-Dextroamphetamine (Adderall)
Dextroamphetamine (Dexedrine, Dextrostat)
Lisdexamfetamine (Vyvanse)

Pemoline (Cylert), another stimulant drug, was withdrawn from the U.S. market in 2005 after several reports of liver failure.

Methylphenidate and Dexmethylphenidate. Methylphenidate drugs (Ritalin, Metadate, Concerta, Daytrana) are the most commonly used psychostimulants for treating ADHD in both children and adults. Dexmethylphenidate (Focalin) is a similar drug. These drugs increase dopamine, a neurotransmitter important for cognitive functions such as attention and focus.

With the exception of Daytrana, all of these drugs are pills taken by mouth. Daytrana, approved in 2006, is the first skin patch drug for ADHD. A patch is applied to the hip each day and delivers a 9-hour dose of methylphenidate.

These drugs are available in short-acting and long-acting dosage forms. The short-acting forms need to be taken several times a day, including during school hours. As the drug wears off, a rebound effect can occur, and ADHD symptoms can intensify. For this reason, the long-acting dosage forms have become popular.

Amphetamine, Dextroamphetamine, and Lisdexamfetamine. Amphetamine-dextroamphetamine (Adderall), dextroamphetamine (Dexedrine, Dextrostat), and lisdexamfetamine (Vyvanse) work by blocking the reabsorption of the brain chemicals dopamine and norepinephrine. Side effects can include stomach problems and mood changes, including sadness, anxiety, and irritability.

Psychostimulant medications are associated with some significant risks. All ADHD stimulant drugs carry warnings that they should not be used by patients with structural heart problems or pre-existing heart conditions (high blood pressure, heart failure, or heart rhythm disturbances). These drugs have been associated with sudden death in children with heart problems. They have also been associated with sudden death, stroke, and heart attack in adults with a history of heart disease. In addition, these drugs may slightly increase the risk for auditory hallucinations, paranoia, and manic behavior even in patients who do not have a history of psychiatric problems. The FDA has directed manufacturers of ADHD medications to warn all patients taking these medicines of their potential cardiovascular and psychiatric risks.

Stimulant drugs may also:

Worsen behavior and thought disturbance in patients with a pre-existing psychotic disorder.
Cause a mixed or manic episode in patients who have both ADHD and bipolar disorder.
Increase aggressive behavior or hostility. Patients beginning stimulant drug treatment should be monitored for worsening of these behaviors.
Slow growth and weight gain in children. Children who take stimulant drugs should have their growth monitored. If they do not gain height or weight at a normal rate, they may need to stop taking the drug.

Side Effects. All stimulants have a number of side effects:

The most common side effects of any stimulant are nervousness and sleeplessness, although some parents have reported improved sleep patterns in their children after taking stimulants.
Tics or jerky, disordered movements occur in about 9% of children.
Other side effects include irritability, stomach pain, headache, depression, hair loss, and lack of spontaneity.

Symptoms of Overdose. Symptoms of overdose include changes in heart rhythm and rate, hypertension, confusion, breathing difficulties, sweating, vomiting, and muscle twitches. If they occur, parents should call the doctor immediately. Even among young people who abuse Ritalin, however, less than 1% experience severe side effects (rapid heart rate, hypertension), and outcomes are generally good. Side effects may be very severe, however, if Ritalin is overused and taken with other drugs. A 2006 study reported that over 3,000 people are treated in hospital emergency rooms due to side effects from ADHD drugs. Sixty-one percent of these visits involved accidental ingestion or overdose.

Concerns for Abuse. Studies on both animals and humans suggest that Ritalin lacks the properties that create addiction, particularly in doses used for treating ADHD. Although methylphenidates have properties similar to amphetamines, their drug levels rise very slowly in the brain at the oral doses given for ADHD. This slow rise prevents a so-called "high" and subsequent addiction to the drug. Some stimulant drugs, such as lisdexamfetamine, may pose a lower risk for abuse than others.

The primary danger for drug abuse from stimulants appears to occur in non-ADHD young people who purchase these drugs illegally. In one study, for instance, 16% of children with ADHD reported pressure from their fellow students to sell or give them their medication. While people ages 18 - 25 are more likely to use ADHD drugs for non-medical uses, children ages 12 - 17 are more likely to suffer adverse effects from medication misuse and to require treatment at an emergency room. If a child abuses another drug (alcohol, prescription medication) along with the ADHD medication, the chance for serious side effects is even greater.

Atomoxetine (Strattera) was the first non-stimulant approved for ADHD in children and the first treatment approved for adult ADHD. The drug works by increasing levels of both norepinephrine and dopamine, which are generally lower than normal in ADHD. The most common side effect is decreased appetite. A few cases of atomoxetine-associated liver injury have been reported, and the FDA has warned doctors that the drug should be discontinued at the first signs of jaundice or liver problems. Long-term effects, such as any impact on growth, are still unknown. Atomoxetine may cause suicidal thinking in children and adolescents, especially during the first few months of treatment. Parents should monitor children taking atomoxetine for any changes in mood or behavior, and immediately contact their doctor if changes occur.

Antidepressants are not FDA-approved for ADHD treatment, but may be helpful in certain circumstances. Because antidepressants appear to work about as well as behavioral therapy, doctors recommend that patients first try psychotherapy before using antidepressants.

Bupropion (Wellbutrin) and tricyclics are the types of antidepressants used for ADHD. Bupropion affects the reuptake of the serotonin, norepinephrine, and dopamine neurotransmitters. Side effects include restlessness, agitation, sleeplessness, headache, and stomach problems. Bupropion should not be used by patients who have a seizure disorder.

Tricyclics are an older type of antidepressant that are effective but have many side effects. Imipramine (Tofranil) and nortriptyline (Pamelor, Aventil) are the tricyclics most commonly prescribed for ADHD. A third tricyclic, desipramine (Norpramin) should only be used if patients are not helped by other tricyclics. (Desipramine has caused sudden death in some children and adolescents.)

Tricyclic antidepressants can cause disturbances in heart rhythm. Children should have an electrocardiogram when they first begin to take this drug, and after any dose increase.

[For more information, see In-Depth Report #8: Depression ].

Alpha-2 agonists stimulate the neurotransmitter norepinephrine, which appears to be important for concentration. They include clonidine (Catapres) and guanfacine (Tenex). They are used for Tourette syndrome and may be beneficial when other drugs have failed for ADHD children with tics or those whose primary symptoms are severe impulsivity and aggression. These drugs are mainly prescribed in combination with a stimulant.

These drugs have a number of side effects. Sedation is the most common. A clonidine skin patch, which gradually releases the medication, helps reduce the sedative effect. Because clonidine slows the heart down, it can have adverse effects in some children. Going off too quickly or missing doses can cause rapid heartbeats and other symptoms that may lead to severe problems. Doctors strongly recommend that no child be given this medication without a preliminary examination for heart problems, and no child with existing heart, kidney, or circulatory problems should take it.

Behavioral Management

Behavioral techniques for managing the child with ADHD are not intuitive for most parents and teachers. To learn them, caregivers may need help from qualified health care professionals or from ADHD support groups. At first, the idea of changing the behavior of a highly energetic, obstinate child is daunting. It is futile and damaging to try to force a child with ADHD to be like most children. It is possible, however, to limit destructive behavior and to instill a sense of self-worth that will help overcome negativity toward life, which is one of the great dangers of the disorder.

Bringing up a child with ADHD, like bringing up any child, is a process. No single point is ever reached where the parent can sit back and say, "That's it. My child is now OK, and I don't have to do anything more." The child's self worth will evolve with an increasing ability to step back and consider the consequences of an action and then to control that action before taking it. But this does not happen overnight. A growing child with ADHD is different from other children in very specific ways, presenting challenges at every age.

Setting Priorities for the Parent. Parents must first establish their own levels of tolerance. Some parents are easygoing and can accept a wide range of behaviors, while others cannot. To help a child achieve self-discipline requires empathy, patience, affection, energy, and toughness. Some tips to help the parents include:

Parents should prepare a list giving priority to those behaviors they think are the most negative, such as fighting with other children or refusing to get up in the morning. The least negative behaviors on the bottom of the list should be ignored temporarily or even permanently (refusing to wear anything but red T-shirts).
Certain odd behaviors that are not hurtful to the child or to others may be an indication of creative or humorous attempts to adapt (making up silly songs or drawing violent pictures). These should be accepted as part of the child's unique and positive development, even if they seem peculiar to the parent.
It is important to keep in mind that no one is a saint. Loving parents who occasionally lose their tempers will not damage their children forever. In fact, non-abusive open disapproval or dismay is far less destructive to both parent and child than harboring resentment beneath a false calm.

Establishing Consistent Rules for the Child. Parents must be as consistent as possible in their approach to the child, which should reward good behavior and discourage destructive behavior. Rules should be well-defined but flexible enough to incorporate harmless idiosyncrasies. It is very important to understand that children with ADHD have much more difficulty adapting to change than do children without the condition. (For example, the child should do homework every day but might choose to start it after a TV show or computer game.)

Managing Aggression. Some useful tips for managing aggression include:

Parents should try to give little attention to mildly disruptive behaviors that allow this energetic child to let off some harmless steam. The parent will also be wasting energy that will be needed when the negative behavior becomes destructive, abusive, or intentional.
The use of "time-out," isolating the child immediately for a short period of time, is an effective measure for allowing both the caregiver and the child to cool down. The child should immediately (and without emotion) be removed from a situation in which they are endangered or endangering others. The child should view time out as a way of cooling off and getting a distance on their behavior, not as isolation from others.
To channel physical aggression and impulsivity in the ADHD toddler, the parents must teach them to use verbal responses. (A parent may need to allow verbal responses that would be unacceptable in another child.)
When the ADHD child becomes older and if the verbal responses become intentionally abusive and socially undesirable, the parent must redirect this form of aggression into more acceptable activities, such as competitive one-on-one sports, energetic music, video games, or big colorful paintings. Competitive video games, such as sports games, may also be an option.
Sometimes a parent can anticipate situations when an ADHD child is likely to misbehave, but all too often the child explodes for no apparent reason. If the blow-up occurs in public, the parents should complete their activities and leave as quickly as possible.

Establishing a Reward System. Children with ADHD respond particularly well to reward systems. One study reported that they performed equally well when encouraged either by a direct reward for a correct response or with the use of a system called response-cost. With this system, the child is given the reward first and allowed to keep it if their behavior remains appropriate.

Some suggested tips for rewarding the ADHD child are:

Create charts with points or stars for good behavior or for completed tasks. It is important to give points for even simple positive behaviors, which may be taken for granted in other children (responding happily to a change in plans, changing an obscenity to a more acceptable expletive).
Rewards for any child can include playing a favorite game with the child, extending bedtime by an hour, or allowing an extra half-hour of TV.
Rewards of food or gifts should be used infrequently, if at all. They can create other problems, such as being overweight, having a bad diet, or making continuous demands for objects.
A reward system should rotate different types of rewards, because such children are easily bored.
Children with ADHD respond better with small rewards promised in the short-term than large rewards offered in the future. One approach that employs both short- and long-term rewards uses a system that gives the child points for specific positive behaviors. As the children accumulate points, they can use them for larger tangible rewards, such as a favorite video game or CD.
Rewards should be promised only when caregivers are fairly certain they can follow through. ADHD children respond with much greater frustration than non-ADHD children to disappointment, and are likely to have a strong (and noisy) negative reaction. A parent must remember that this response is part of the ADHD child's make-up and not necessarily in their control.

Improving Concentration and Attention. Research indicates that ADHD children perform significantly better when their interest is engaged. Parents should be on the lookout for activities that hold the child's concentration. Some options that may help an ADHD child to focus include:

Many ADHD children are particularly lured by the computer, which is a very promising tool. A number of non-violent computer games are available that offer problem-solving techniques using characters, narrative, and humor.
Swimming, tennis, and other sports that focus attention and limit peripheral stimuli are often appealing. ADHD children often do not do well with team sports, although they are interested. Children with ADHD are less likely to become distracted in sports that require constant alertness, such as football or basketball. In baseball, positions such as pitching or catching are preferable to the outfield, where attention easily wanders. Finding a coach that understands the child’s difficulties is very helpful.
Some experts are enthusiastic about martial arts, such as Tae Kwon Do, which can offer an appropriate and controlled emotional outlet, help to focus attention, and teach self-restraint, self-discipline, and tolerance. Care should be taken to select an instructor who makes such goals a priority.
Learning an instrument may be one of the best ways for an ADHD child to develop a more rhythmic and balanced sense of self. Music, even simply listening to it, is often very important for these children. (Parents may have to tolerate music that does not please them.)

Even if a parent is successful in managing the child at home, difficulties often arise at school. The ultimate goal for any educational process should be the happy and healthy social integration of the ADHD child with their peers.

Preparing the Teacher. Although teachers can expect at least one student in every classroom to have ADHD, there is currently little training that prepares them for managing these children. The teacher should be prepared for the certain behaviors in the child with ADHD:

Students with ADHD are often demanding, talkative, and highly visible.
Inattention is a major factor in low academic performance. It causes them to frequently forget homework or miss assignments. Children with ADHD often require frequent reminders or visual cues (such as posters) for rules and regulations. Having the child sit in the front of the classroom may be helpful for both increasing attention and reducing noisy activity.
Lack of fine motor control makes taking notes very difficult, and handwriting is often poor. Using a typewriter or computer can compensate for this. One useful skill that has helped some children is learning to type at an early age, around the third or fourth grade.
Rote memorization and math computation, which require following a set of ordered steps, are often difficult. (Children with ADHD may do better with math concepts.)
Many children with ADHD respond well to school tasks that are rapid, intense, novel, or of short duration (such as spelling bees or competitive educational games), but they almost always have problems with long-term projects where there is no direct supervision.

The Role of the Parent in the School Setting. The parent can help the child by talking to the teacher before the school year starts about their child's situation:

The first priority for the parent is to develop a positive, not adversarial, relationship with the child's teacher.
The parent must acknowledge the teacher's situation, for the teacher must deal not only with the ADHD child's behavior but also with the needs of all the other children.
Frequent brief and sympathetic conversations with the teacher can be helpful and can lead to coordination of efforts, particularly if they provide reciprocal information about progress or setbacks.
Finding a tutor to help after school may be helpful. It is not clear, however, if tutoring offers significant benefits for children whose academic problems stem from inattention unless it is structured specifically to address this problem.

Special Education Programs. The Individuals with Disabilities Education Act (IDEA) requires the school to identify and evaluate children who may need help and to provide special services. However, parents sometimes report pressure by the school to put their children on medication or force them into special classrooms without clear educational justification. The schools, in these cases, may be acting illegally.

High-quality special education can be extremely helpful in improving learning and developing a child's sense of self worth. Many families, however, may not have appropriate programs available for them. Programs vary widely in their ability to provide quality education. Parents must be aware of certain limitations and problems with special education:

Special education programs within the normal school setting often increase the child's feelings of social alienation.
If the educational strategy focuses only on abnormal behavior, it will fail to take advantage of the creative, competitive, and dynamic energy that often accompanies ADHD behavior.
There is no federally funded special education category specifically targeted to ADHD.

If, in fact, ADHD is as common as studies are indicating, the best approach may be to treat the syndrome as a variant of the norm and train teachers to manage these children within the context of a normal classroom.

Special programs are also required under the Rehabilitation Act and by the Americans with Disabilities Act (ADA) for students at institutions of higher learning. It is the student's responsibility, however, to inform the administration at their college or university that they need such services. Unfortunately, many college students are reluctant to do this, although such programs can provide important and beneficial assistance in improving their academic performance.

Other Treatments

A number of diets have been suggested for people with ADHD. Several well-conducted studies have failed to support dietary effects of sugar and food additives on behavior, except possibly in a very small percentage of children. Still various studies have reported behavioral improvement with diets that restrict possible allergens in the diet. Parents may want to discuss with their doctor implementing an elimination diet of certain foods that would not be harmful and that might help.

Food Allergies. Evidence suggests that children with behavioral difficulties may be sensitive to certain chemicals in foods. Studies vary widely, however, on how many cases of ADHD may be associated with sensitivities or allergies to food chemicals or additives, with results ranging widely from 5 - 62%. Among the suspected additives and foods that parents and studies report as inciting behavioral changes are the following:

Any artificial colorings (particularly yellow, red, or green)
Other chemical additives -- for example, BHT or BHA
Milk
Chocolate
Eggs
Wheat
Foods containing salicylates, including all berries, chili powder, apples and cider, cloves, grapes, oranges, peaches, peppers (bell & chili), plums, prunes, tomatoes

In one small study, 62% of children who were given only rice, turkey, pears, and lettuce to eat for 2 weeks experienced at least a 50% improvement in symptoms. Nevertheless, about a quarter of the children pulled out because they could not stick with the diet or they became ill.

Feingold Diet. The most well-known diet for ADHD is the Feingold diet, a salicylate- and additive-free diet, which requires rigorous vigilance over a child's eating habits. This diet also prohibits aspirin, which contains salicylates. Some parents report great success with this diet, although it may be difficult to impose. One study that reported the diets efficacy suggested that it might not provide enough nutritive value, although the diet provides a wide range of healthy foods to select from. It is certainly wise, in any case, to avoid food with artificial colors and flavors and to provide a healthy balance of fresh, natural foods.

Essential Fatty Acids. Omega-3 fatty acids, found in fatty fish and certain vegetable oils, are important for normal brain function and may have some benefits for people with ADHD. It is not clear if supplements of fatty acid compounds, such as docosahexaenoic acid (DHA) and eicosapentaneoic acid (EPA), provide any advantages.

Zinc. Zinc is important for the metabolism of certain neurotransmitters that play a role in ADHD, and deficiencies have been associated with some cases of ADHD. Long-term use of zinc, however, can cause anemia and other side effects in people without deficiencies and it has no effect on ADHD in these patients. In any case, testing for trace minerals, such as zinc, is not standard procedure when evaluating children suspected to have ADHD.

Sugar. Although parents often blame sugar for causing children to become impulsive or hyperactive, a number of studies strongly indicate that sugar plays no role in hyperactivity. One study reported, in fact, that ADHD children had fewer problems after a high-carbohydrate breakfast than after a high-protein one. Another reported that children actually moved more slowly after a high-sugar meal, suggesting the carbohydrates may have a sedative effect. (Still, it's probably always wise for any child to cut down on sugar.)

Techniques that use biologic or auditory feedback are proving to be effective tools for increasing children's attention -- a primary factor in low academic performance.

Neurofeedback. Neurofeedback is an approach that uses electronic devices to help the child control their own brain wave activity. Electrodes are pasted to the child's head and pick up signals from the brain. The child watches images, such as moving graphs, on a computer monitor that reflect the child's brain wave activity. Children are then taught certain high-level mental activities at the point when feedback information on the screen indicates that they are fully concentrating. Children usually attend forty 50-minute sessions, usually twice a week. Small studies have reported significant improvement in inattention, impulsivity, and response time.

Interactive Metronome and Musical Therapy. Interactive metronome uses feedback from sound to improve attention, motor control, and certain academic skills. In this technique study, children wear headphones and sensors on their hands and feet. They perform a number of exercises to a rhythmic computer-beat. Training sessions are completed in 3 - 5 weeks. Some small studies have reported improvement in attention, motor control, language processing, and behavior. (In support of this, some parents report that learning a musical instrument helped their children significantly.)

Procedures and Non-Drug Therapies. A number of alternative approaches are used for children and adults with mild ADHD symptoms. For example, daily massage therapy may help people with ADHD feel happier, fidget less, be less hyperactive, and focus on tasks. Other alternative approaches that may be helpful include relaxation training, meditation, and music therapy. Based on existing evidence, these treatments may be helpful for symptom management but are not proven to benefit the underlying disorder.

Natural Remedies. A number of parents resort to alternative remedies as an alternative to psychostimulants and other drugs. Small trials have found some herbs and supplements -- such as oral flower essence, ginkgo biloba, panax ginseng, melatonin, and pine bark extract (Pycnogenol) --may possibly have benefits for ADHD. Based on existing evidence, however, none can be recommended, particularly for children.

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been a number of reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.

The following are special concerns for people taking natural remedies for attention-deficit disorders:

Melatonin. High doses of melatonin have been associated with an increased risk for seizures in children with existing neurologic disorders.
Gingko. The risk for side effects from gingko appear to be low, but there is an increased risk for bleeding and interaction with anti-clotting medications at high doses.
Ginseng. There have been contaminated forms of imported ginseng. Ginseng also has been associated with low blood sugar and a higher risk for bleeding. In addition, a great number of ginseng products have been found to contain little or no ginseng.
