Attention deficit hyperactivity disorder (ADHD) is a brain disorder that affects how you pay attention, sit still, and control your behavior. It happens in children and teens and can continue into adulthood.
ADHD is the most commonly diagnosed mental disorder in children. Boys are more likely to have it than girls. It’s usually spotted during the early school years, when a child begins to have problems paying attention.
ADHD can't be prevented or cured. But spotting it early, plus having a good treatment and education plan, can help a child or adult with ADHD manage their symptoms.
Symptoms are grouped into three types:
Inattentive. A child with ADHD:
Is easily distracted
Doesn't follow directions or finish tasks
Doesn't seem to be listening
Doesn't pay attention and makes careless mistakes
Forgets about daily activities
Has problems organizing daily tasks
Doesn’t like to do things that require sitting still
Often loses things
Tends to daydreamHyperactive-impulsive. A child with ADHD:
Often squirms, fidgets, or bounces when sitting
Doesn't stay seated

Is always moving, such as running or climbing on things. (In teens and adults, this is more often described as restlessness.)
