[Neurologic manifestations of periodic disease].

Results of comprehensive neurological examinations of 4 patients suffering from periodic disease have shown that the latter may be not only a disease entity, but also a syndrome characterizing some organic affections of the brain. The abdominal and other crises of the periodic disease included cerebrovascular disturbances which manifested hemipareses, syncopes, and migraine-like cephalgia. EEG and REG examinations have revealed dysfunction of the mesodiencephalic structures which, probably, underlies the pathogenesis of the periodic disease. The knowledge of the formerly almost unexplored neurological manifestations of the periodic disease will contribute to improvement of the therapy of this rare ailment.
