[Fahr's disease (idiopathic non-atherosclerotic calcification of the cerebral arteries)]

The authors describe one case of Fahr's disease in a 69-year-old male. The disease was characterized by a rapid development with polymorphic subcortical symptoms (mainly hyperkinetic) and a rapid disintegration of intellectual functions. Besides that, cortical and pyramidal disturbances (hemiparesis, visual disorders, etc.) were also marked. In the postmortem examination selective calcifed cerebral vessels were found, typical for this form of the disease. This observation gave no supplementary data on the etiology of the disease. Laboratory data did not depict any deviation from the norm.
