Hyperactivity, Conduct Disorder, Attention Deficits, and the Concept of Minimal Brain Dysfunction
Minimal brain dysfunction (MBD) has been described as a syndrome that includes a very broad spectrum of deviant behaviors. It is almost without exception a childhood diagnosis. The typical MBD child is thought to display symptoms of overactivity, impulsivity, clumsiness, and school-learning problems. In addition, aggressiveness, disobedience, and delinquent behavior are often cited as being associated with the syndrome. However, the MBD child is usually defined within the normal range of intelligence, thus eliminating the mentally retarded from this diagnostic category. The concept is losing its popularity because in most cases there is no evidence of any brain damage, which is seemingly invoked because of similarity in behavior of these children to patients with known brain damage.
