Attention deficit hyperactivity disorder (ADHD) is a problem of not being able to focus, being overactive, not being able control behavior, or a combination of these. For these problems to be diagnosed as ADHD, they must be out of the normal range for a person's age and development.
ADD; ADHD; Childhood hyperkinesis
ADHD usually begins in childhood, but may continue into the adult years. It is the most commonly diagnosed behavioral disorder in children. ADHD is diagnosed much more often in boys than in girls.
It is not clear what causes ADHD. A combination of genes and environmental factors likely plays a role in the development of the condition. Imaging studies suggest that the brains of children with ADHD are different from those of children without ADHD.
Symptoms of ADHD fall into three groups:
Some people with ADHD have mainly inattentive symptoms. Some have mainly hyperactive and impulsive symptoms. Others have a combination of different symptom types. Those with mostly inattentive symptoms are sometimes said to have attention deficit disorder (ADD). They tend to be less disruptive and are more likely not to be diagnosed with ADHD.
If ADHD is suspected, the person should be evaluated by a health care professional. There is no test that can make or exclude a diagnosis of ADHD. The diagnosis is based on a pattern of the symptoms listed above. When the person with suspected ADHD is a child, parents and teachers are usually involved during the evaluation process.
Most children with ADHD have at least one other developmental or mental health problem. This problem may be a mood, anxiety or substance use disorder; a learning disability; or a tic disorder. A doctor can help determine whether these other conditions are present.
Treating ADHD is a partnership between the health care provider and the patient. If the patient is a child, parents and often teachers are involved. For treatment to work, it is important to:
If treatment does not seem to work, the health care provider will likely:
Medicine combined with behavioral treatment often works best. There are several different ADHD medicines that may be used alone or in combination. The health care provider will decide which medicine is right based on the person's symptoms and needs.
Psychostimulants (also known as stimulants) are the most commonly used ADHD medicines. Although these drugs are called stimulants, they actually have a calming effect in people with ADHD.
Follow the health care provider's instructions on how to take ADHD medicine.
Some ADHD medicines have side effects. If the person has side effects, contact the health care provider right away. The dosage or medicine itself may need to be changed.
Therapy for both the patient and if relevant, the family, can help everyone understand and gain control of the stressful feelings related to ADHD.
A common type of ADHD therapy is called behavioral therapy. It teaches children and parents healthy behaviors and how to manage disruptive behaviors. For mild cases of ADHD, behavioral therapy alone (without medicine) can sometimes be effective.
Support groups can help the person and family connect with others who have similar problems.
Other tips to help a child with ADHD include:
There is little proof that alternative treatments for ADHD such as herbs, supplements, and chiropractic are helpful.
ADHD is a long-term, chronic condition. If it is not treated correctly, ADHD may lead to:
One third to one half of children with ADHD continue to have symptoms of inattention or hyperactivity-impulsivity as adults. Adults with ADHD are often able to control behavior and mask difficulties.
Call the doctor if you or your child's school staff suspect ADHD. You should also tell the doctor about:
