Fahr disease is a rare sporadic or familial idiopathic basal ganglia calcification associated with neurologic disorders, such as movement disturbances and dementia. More rarely, schizophrenia-like psychosis characterized by paranoia, hallucinations, and delusions has also been reported to be associated with Fahr disease.
