Familial Idiopathic Basal Ganglia Calcification (Fahr's syndrome): Initial Clinical Neuropsychiatric Presentation without Corresponding Neurological Deficit

摘要

Familial idiopathic basal ganglia calcification (FIBGC) or Fahr's syndrome is a rare disorder with various clinical presentations which can mimic - in particular - psychiatric illness. The following case is characterized by the typical basal ganglia calcifications and presentation of neuropsychiatric symptoms indicating the first clinical presentation in the absence of a neurological deficit. As previously reported, the extent of calcification did not predict neurological impairment, however, predicted severe psychosis.
