Commentary on "Basal Ganglia Calcification: A Case Report of Fahr Disease With Pure Psychiatric Symptoms".

Abstract

Fahr disease, also known as familial idiopathic basal ganglia calcification, is a rare neurodegenerative disorder, the etiology of which remains unknown. Given its various presentations, Fahr disease is presumed to be underdiagnosed and its prevalence underestimated. We present a case of Fahr disease that presented mainly with pure psychiatric symptoms. Isolated psychiatric symptoms without neurological manifestations are rarely seen in patients diagnosed with Fahr disease. Psychiatrists should consider Fahr disease as a differential diagnosis in the evaluation of psychiatric illness.
