What is ADHD

Attention deficit hyperactivity disorder (ADHD) is a chronic behavioral disorder of childhood onset by age seven. It is characterized by behavior that is hyperactive, impulsive or inattentive. These behaviors must persist for at least six months and be present in two environments such as home, work or school.

ADHD affects children, adolescents, and adults. The cause of ADHD is unknown. It most likely is caused by a chemical imbalance in the brain. There also appears to be a genetic factor since ADHD can run in families.

Medications can help control behavior and increase attention span. Stimulants are the most common treatment for ADHD. They increase activity in parts of the brain that appear to be underactive in children with ADHD.
