Attention deficit hyperactivity disorder (ADHD) is a problem caused by the presence of 1 or more of these findings: not being able to focus, being overactive, or not being able control behavior.
ADD; ADHD; Childhood hyperkinesis
ADHD often begins in childhood. But it may continue into the adult years. ADHD is diagnosed more often in boys than in girls.
It is not clear what causes ADHD. It may be linked to genes and home or social factors. Experts have found that the brains of children with ADHD are different from those of children without ADHD. Brain chemicals are also different.
ADHD symptoms fall into three groups:
Some people with ADHD have mainly inattentive symptoms. Some have mainly hyperactive and impulsive symptoms. Others have a combination of these behaviors.
Many of the above findings are present in children as they grow. For these problems to be diagnosed as ADHD, they must be out of the normal range for a person's age and development.
There is no test that can diagnose ADHD. Diagnosis is based on a pattern of the symptoms listed above. When a child is suspected to have ADHD, parents and teachers are often involved during the evaluation.
Most children with ADHD have at least one other developmental or mental health problem. This may be a mood, anxiety, or substance use disorder. Or it may be a learning problem or a tic disorder.
Treating ADHD is a partnership between the health care provider and the person with ADHD. If it's a child, parents and often teachers are involved. For treatment to work, it is important to:

Medicine combined with behavioral treatment often works best. Different ADHD medicines can be used alone or combined with each other. The doctor will decide which medicine is right, based on the person's symptoms and needs.
Psychostimulants (also known as stimulants) are the most commonly used medicines. Although these drugs are called stimulants, they actually have a calming effect in people with ADHD.
Follow the health care provider's instructions about how to take ADHD medicine. The provider needs to monitor if the medicine is working and if there are any problems with it. So, be sure to keep all appointments with the provider.
Some ADHD medicines have side effects. If the person has side effects, contact the doctor right away. The dosage or medicine itself may need to be changed.
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 ADHD, behavioral therapy alone (without medicine) may be effective.
