History of attention-deficit hyperactivity disorder - Wikipedia, the free encyclopedia:
Hyperactivity has long been part of the human condition. Sir Alexander Crichton describes "mental restlessness" in his 1798 book. The terminology used to describe the symptoms of ADHD has gone through many changes over history including: "minimal brain damage", "minimal brain dysfunction", "learning/behavioral disabilities" and "hyperactivity". In the DSM-II (1968) it was the "Hyperkinetic Reaction of Childhood". In the DSM-III "ADD (Attention-Deficit Disorder) with or without hyperactivity" was introduced. In 1987 this was changed to ADHD in the DSM-III-R and subsequent editions.
