Neurosurgical treatment of the dyskinesias

Abstract

I have attempted to review what I consider to be the principal conclusions of a 25 year study of the neurosurgical treatment of the dyskinesias. The concept that the pathological disinhibition which is responsible for the production of these syndromes can be modified by destructive lesions within the thalamus or by prosthetic mobilization of inhibitory mechanisms of the cerebellum is supported by the results presented in this report. Neurosurgical treatment of the dyskinesias is potentially a relatively safe and efficacious means of alleviating incapacitation of a large group of patients. However, meticulous attention to patient selection as well as adherence to the general principles of surgical technique which have been reviewed are essential if the full potential of these approaches is to be realized.
