Neuropathological findings in primary generalized epilepsy: a study of eight cases

Abstract

On neuropathological investigation of eight cases with primary generalized epilepsy, none showed elective parenchymal necrosis, which is regarded (qualitatively and topologically) as characteristic of epilepsy in classical neuropathology. In seven of the eight cases, however, marked microdysgenesis with varying regional distribution was found. These maturation disturbances are to be interpreted as pathological and refute the currently held view that there is no evidence of pathological brain damage in primary generalized epilepsy.
