Functional microsurgical partial callosotomy in patients with secondary generalized epilepsies. I. Disruption of bilateral synchrony of spike and wave discharges.
Fourteen patients with secondary generalized epilepsy suffering from multiform seizures (MS) not amenable to medication were submitted to partial section of the corpus callosum. In all patients, there was a partial disruption of the previous generalized bilateral synchronous epileptiform discharges (GBSD). The electroencephalographic findings after callosal section are discussed with respect to their implications in furthering our understanding of the mechanisms subserving the organization of GBSD.
