The Reduction of Seizures in Cerebral Palsy and Epileptic Patients Using Chronic Cerebellar Stimulation

Abstract

With the use of chronic cerebellar Stimulation (CCS) for the reduction of spasticity and improvements of Performance in our clinic since 1974, 329 spastic patients (89% cerebral palsy) were implanted and studied. Ninety-five (29%) had had a history of seizures prior to the implantation. Group 1 comprised 65 patients (20%) who had no seizures in the 3 years prior to implantation, none had had a seizure during the CCS period (average 4.3 year/patient). Group 2 comprised 30 patients (9%) who were having seizures although under medical care during the 3 years prior to implantation; of the 19 having grand mal seizures 15 stopped and 3 were reduced, of the 8 having petit mal 4 stopped and 2 were reduced, of 5 having myoclonic episodes 1 stopped and 3 were reduced. Overall CCS effects on the 27 patients followed in Group 2 for an average of 4.3 year/patient showed 17 (63%) stopped seizuring, 7 (25%) reduced and 3 (12%) no effect.
