Bilateral Basal Ganglia Calcifications Manifesting as Psychosis With Manic Features: A Case Report on Fahr's Syndrome.

Fahr's syndrome is a rare neurodegenerative disorder characterized by symmetric bilateral calcifications in the basal ganglia. While this is largely a hereditary disease with autosomal dominant inheritance, a small percentage is sporadic in nature with no metabolic or other underlying causes identified. Fahr's syndrome has both neurological and psychiatric manifestations that include movement abnormalities, seizures, psychosis, and depression.
