[Status epilepticus and multiple sclerosis (author's transl)].
Status epilepticus was a complicating feature of the last bout before the fatal outcome in a patient with a 11 years history of multiple sclerosis. The fits were seen as clonic movements of the eyes in a lateral direction, lasting for 30 to 90 seconds and repeated every 5 minutes on average. Electroencephalographic recordings demonstrated periodic slow spikes on the right hemisphere, starting in the anterior region. Neuropathological data eliminated an associated pathological condition and suggested that the development of acute cortico-subcortical demyelinating lesions was responsible of the epilepsy. The type of electrical activity observed, localized to one hemisphere, is found with recent ischemic lesions, and less frequently in cases of cerebral tumor, necrotizing encephalitis, metabolic encephalopathies or post traumatic disorders. A case with similar clinical and electroencephalographic features in a patient with multiple sclerosis has been reported in the literature.
