Attention deficit hyperactivity disorder (ADHD) is a behavioral problem in children in which there is a consistently high level of activity, impulsiveness, and difficulty attending to tasks. The cause is unknown, although the disorder tends to run in families, so a genetic factor may be involved. Symptoms usually develop between about the ages of 3 and 7 years.
They may include a short attention span; an inability to finish tasks; difficulty in following instructions; a tendency to talk excessively and interrupt others; difficulty waiting or taking turns; constant fidgeting; an inability to play quietly alone; and frequently acting without thinking.
Treatment may be with therapy, medication, or both. Therapy may involve psychotherapy and social skills training, as well as training and education for parents. Medications can help to control the symptoms—for example, by aiding concentration and reducing impulsiveness.
Symptoms of ADHD usually diminish with time, although the condition may sometimes persist into adulthood
