Attention-deficit/hyperactivity disorder (AD/HD) is a neurobiological disorder. It is characterized by developmentally inappropriate impulsivity, inattention, and in some cases, hyperactivity. Although individuals with AD/HD can be very successful in life, without appropriate identification and treatment, AD/HD can have serious consequences. These consequences may include school failure, depression, conduct disorder, failed relationships, and substance abuse. Early identification and treatment are extremely important.

CHADD (Children and Adults with Attention-Deficit/Hyperactivity Disorder) is the nation’s leading non-profit organization serving individuals with AD/HD and their families. CHADD has over 16,000 members in 200 local chapters throughout the U.S. Chapters offer support for individuals, parents, teachers, professionals, and others. More about CHADD
