title: [Postural hypotension with myoclonia in multisystemic atrophy].
abstract: Each time he stood up a 60-year old man experienced myoclonic jerks, quickly followed by a syncope due to major postural hypotension. Progressive autonomic failure was associated with pyramidal, extrapyramidal and cerebellar features in a pattern characteristic of Shy-Drager disease. Myoclonic jerks suggested seizures, but no electroencephalographic epileptiform activity was found. This case together with data from the literature suggest, that such involuntary movements may result from cerebral anoxia.
