The number of parent-reported cases of childhood Attention-Deficit/Hyperactivity Disorder (ADHD) has risen dramatically in the past several years according to the Centers for Disease Control. Since 2003 there was a 22% increase in the percentage of U.S. children ages 4–17 with a parent-reported ADHD diagnosis; in 2007, an estimated 5.4 million U.S. children had a reported history of an ADHD diagnosis and 2.7 million were taking ADHD medication.
The report is based on analyses of telephone survey data from the National Surveys of Children's Health from 2003–2004 and 2007–2008. ADHD is a neurobehavioral disorder that is characterized by developmentally inappropriate levels of inattention and hyperactivity resulting in functional impairment.
