Definition and History of ADHD

Abstract

ADHD, the abbreviation for Attention-Deficit/Hyperactivity Disorder, is the name coined to describe children, adolescents, and some adults, who are inattentive, easily distracted, abnormally overactive, and impulsive in their behavior. ADHD is a neurobiological ``syndrome,'' not a ``disease,'' with a specific known cause. Many different factors have been suggested as the cause of ADHD. The treatment requires several different approaches, involving medical, neuropsychological, educational, and parental disciplines. It is a ``heterogeneous'' disorder.
