According to the findings of a 2011-2012 CDC (Center for Disease Control) study of some 76,000 families, one in five high-school age boys in the United States and 11 percent of school-age children have received a medical diagnosis of Attention Deficit Hyperactivity Disorder (ADHD). ADHD is described by most experts as resulting from abnormal chemical levels in the brain that impair a person’s impulse control and attention skills.
