First published in 1988. This book grew out of an European Brain and Behaviour Society Workshop on Attention Deficit Disorder, Minimal Brain Dysfunction, Hyperkinetic Syndrome, and related dysfunctions held in Oslo, Norway in 1987. Virtually millions of children and adults suffer from problems variously described as attention deficit disorder (ADD), minimal brain dysfunction (MBD), hyperkinetic syndrome, or, most recently, attention- deficit hyperactivity disorder (ADHD). A main conclusion of the conference was that the attention problems of ADD children might be secondary to basic motor-control problems.
