What is ADHD?

Attention deficit hyperactivity disorder (ADHD) is a disorder that affects behavior. A recent national study reported by the CDC noted that 11% of school aged children are being diagnosed with ADHD. Three main symptoms define ADHD including inattention, hyperactivity, and impulsivity. The symptoms are severe enough to affect the child's behavior in social situations and at school. The criteria for ADHD diagnosis were established in the Diagnostic and Statistical Manual of Mental Health (DSM-IV; American Psychiatric Association) in 1994. To be diagnosed with ADHD, a child must exhibit the symptoms outlined in this slideshow for at least six months.

Early recognition is key to treatment of ADHD

Early diagnosis and treatment of ADHD increases the possibility of long-term success for children with the condition. It can be difficult to diagnose ADHD because many of the symptoms are considered "normal" in very young, non-ADHD children. Symptoms in these children eventually go away. The symptoms of ADHD also mimic those of other conditions. A thorough evaluation by a skilled health care professional is necessary to diagnose ADHD. A parent or teacher who suspects ADHD in a child should recommend that child for an evaluation right away.
