Overview

Attention-deficit/hyperactivity disorder (ADHD) affects from 3 percent to 5 percent of American children of school age. The disorder is usually suspected if the child is inattentive, impulsive and hyperactive. Because as many as 50 percent of these children have associated hyperactivity, it is commonly referred to as ADHD. About half of the children with ADHD continue to have it when they grow up.
Unidentified and untreated, the condition can leave your child at risk for:
- Poor performance at school.
- Poor self-image.
- Social problems.
- Family difficulties.
Children may have a high energy level and lots of activity without having the disorder.
Prognosis
Early diagnosis, intervention and treatment can help people with ADHD overcome their problems and achieve success in all areas of their lives. ADHD does not have a cure. Adults who were never diagnosed as children can be successfully treated with medication and lifestyle modifications such as keeping lists.
