What is AD/HD?

We may all occasionally have difficulty sitting still, paying attention, or controlling impulsive behavior. But for some children and adults, the problem is so pervasive and persistent that it interferes with their daily lives at home, at school, at work, and in social settings.

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.

Until recent years, it was believed that children outgrew AD/HD in adolescence. This is because hyperactivity often diminishes during the teen years. However, it is now known that many symptoms continue into adulthood. If the disorder goes undiagnosed or untreated during adulthood, individuals may have trouble at work and in relationships, as well as emotional difficulties such as anxiety and depression.
