Attention-deficit hyperactivity disorder
Attention-deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by significant difficulties of inattention or hyperactivity and impulsivity or a combination of the two. The symptoms appear before a person is twelve years old, are present for more than six months, and cause problems in at least two settings (such as school, home, or recreational activities). In children, problems paying attention may result in poor school performance. Although it causes impairment, particularly in modern society, many children with ADHD have a good attention span for tasks they find interesting.
