Probably as many as four million children and four to five million adults in the United States suffer from Attention- Deficit Hyperactivity Disorder (ADHD). Although ADHD was described by physicians many years ago, its frequency only recently has been recognized. Exact figures are not available, but it seems likely that between 3 to 10 percent of school-age children and 4 to 5 percent of adults have ADHD.

Although the behavioral problems that make up ADHD and the academic problems associated with learning disorders often occur together in the same person, it is useful to view each disorder separately....................
