Fahr's Syndrome Presenting As Pre-senile Dementia With Behavioral Abnormalities: A Rare Case Report.

Fahr's syndrome is a rare neurological disorder characterized by bilateral basal ganglia calcification. Calcification may also involve other brain areas like dentate nuclei of the cerebellum, thalamus, cerebral cortex, hippocampus, and subcortical white matter. Many cases of Fahr's syndrome present with movement disorders, but may also present with dementia, psychiatric manifestations, and language difficulties. Fahr's syndrome generally occurs secondary to metabolic abnormality mainly hypoparathyroidism. Fahr's disease is another variant that is characterized by idiopathic bilateral calcification of basal ganglia in absence of any evident etiology. The present case report presented a rare case of Fahr's syndrome secondary to hypoparathyroidism presenting with pre-senile dementia with behavioral abnormalities.
