Introduction
Epidemiology of ADHD
According to the American Psychiatric Association, approximately 3-7% of all school-age children suffer from ADHD. Other reports claim that up to 12% of children suffer from ADHD. The incidence in boys is reported to be at least three times that of girls (some report as high as 9 times that of girls). However, it is not clear if this is because boys are diagnosed differently than girls or if fewer girls are referred for evaluation because they may manifest symptoms differently than boys. The Centers for Disease Control and Prevention estimates that there are more than 2 million school-age children in the United States with ADHD. Approximately 4% of adults are thought to be diagnosed with ADHD.
