Autism: the treatment of aggressive behaviors.

Eight consecutive cases of adults with the diagnosis of early infantile autism and who were treated with a betablocker are presented. Each had been on various and multiple drug, educational, and behavioral regimens to help control aggressive and self-abusive behavior. Most had been institutionalized from an early age, and a broad range of IQs and speech capacities are represented. Results show the betablockers to have a remarkable effect potentiating measurable diminution in previously intractable aggressive behavior and in many cases the decrease or withdrawal of their neuroleptic.
