Abstract
On neuropathological investigation of 8 cases with primary generalized epilepsy, none showed elective parenchymal necrosis, which is regarded (qualitatively and topologically) as characteristic of epilepsy in classical neuropathology. In 7 of the 8 cases, marked microdysgenesis with varying regional distribution was found. These maturation disturbances are interpreted as pathological and refute the currently held view that there is no evidence of pathological brain damage in primary generalized epilepsy.
