Abstract

Fahr's syndrome involves calcification of basal ganglia and dentate nuclei of the cerebellum. Clinically it may present with an array of movement disorders, dementia and other behavioural disturbances. Sporadic and familial cases have been reported with or without calcium/phosphorus metabolism. A rare form of frontotemporal dementia with neurofibrillary tangles and Fahr-type calcifications (DNTC) has been observed mainly in Japan. We report the singular case of a 50-year-old woman with progressive dementia but neither extrapyramidal symptoms nor a metabolic disorder. Brain CT showed Fahr-type calcifications in the basal ganglia, cerebellum and centrum semiovale as well as temporal atrophy; MRI showed diffuse atrophy predominantly in parietotemporal regions. The clinical and radiological features of our patient point to this uncommon form of dementia.
