Fahr's Disease and Hypoparathyroidism - A Missing Link.

Fahr's disease is an idiopathic basal ganglia calcification with autosomal dominant inheritance. Prior to diagnosing Fahr's disease based on computed tomography (CT) and/or magnetic resonance imaging (MRI) of the brain, one should rule out hypoparathyroidism (HP), and pseudohypoparathyroidism (PHP). Treatments of these conditions are entirely different. HP- and PHP-related hypocalcemia requires calcium, calcitriol, and vitamin D therapy in a long run to avoid recurrent seizures whereas Fahr's disease is treated with an antiepileptic alone.
