Attention Deficit Hyperactivity Disorder (ADHD)

Approximately 3 to 5 percent of school-age children have Attention Deficit Hyperactivity Disorder (ADHD), with some estimates going much higher. The condition causes a child to have difficulty staying focused and controlling their energy and behavior. Children and teens with ADHD often have problems at home, school and with friends.
