Attention-deficit/hyperactivity disorder.

摘要

Attention-deficit/hyperactivity disorder (ADHD) is a common neurobiologic disorder characterized by developmentally inappropriate levels of inattention, hyperactivity, and impulsivity. ADHD also is one of the most prevalent chronic health conditions affecting school-age children. Consequently, physicians frequently are asked to evaluate children for a possible diagnosis of ADHD. The importance of an appropriate and timely diagnosis is based on the knowledge that children who have ADHD may experience difficulty in social, emotional, and academic domains and that treatment can improve outcomes for these children.
