HISTORY AND BACKGROUND
ADHD (Attention Disorder Hyperactivity Disorder) was first mentioned in 1920. British patrician Sir George Still described "an abnormal defect of moral control in children." He found that some affected children could not control their behavior the way a typical child would, but they were still intelligent.

HOW DOES ADHD IMPACT THE BRAIN?
HOW MIGHT HEREDITY OR GENETICS PLAY IN THE ROLE OF ADHD
ADHD runs in the family. Anywhere from one-third to one-half of the parents with ADHD will have a child with this disorder. There are genetic characteristics that seem to be passed down.
If a parent has ADHD, a child has more than a 50% chance of having it. If an older sibling has it, a child has more than a 30% chance.
