Overview

Attention-deficit/hyperactivity disorder (ADHD) is a psychiatric disorder and, more specifically, a chronic neurobehavioral syndrome. ADHD manifests as inattention, impulsivity, and hyperactivity. The term attention-deficit disorder (ADD) refers to the condition without hyperactivity.

People with ADHD tend to overlook details and to miss information. Because of attention deficit, people with ADHD become averse to tasks that require concentration, decisiveness, and organizational skills and may avoid situations where they are expected to perform or to take responsibility for their effort.

Incidence and Prevalence

ADHD may affect as many as 10% of the population in the United States. Approximately 5% of children ages 9 to 17 are affected at any given time, and a possible 2–4% of adults are affected. The occurrence of ADHD is reported worldwide; statistical variations may be due to cultural perceptions of behavior.

Most studies show that boys are affected approximately five times more often than girls. Other studies suggest that ADHD may not be diagnosed as often in girls because girls with ADHD present their symptoms differently.
