How common is Attention Deficit Hyperactivity Disorder?

Estimates vary, but between five and ten percent of children are thought to have ADHD, and perhaps between one and two percent of teenagers and adults. ADHD affects people of all races and socioeconomic backgrounds. Recently, ADHD has gotten a lot of media attention, and there is some degree of controversy surrounding it. Some people feel that ADHD is over-diagnosed, while others believe that ADHD is not a real disorder at all. The truth is, however, that ADHD related symptoms can cause real emotional disturbances, and they can be treated.
