Treatment of Ectopic Calcification in Fahr's Disease or Syndrome

Fahr's disease or syndrome are neurodegenerative diseases in which patients present with bilateral vessel associated calcifications in the basal ganglia. The clinical penetration of Fahr's disease or syndrome is incomplete and heterogeneous comprising of neuropsychiatric signs, cognitive decline, movement disorders, and various other signs (migraine, speech disorders, pain, seizures). The symptoms start between 30 and 50 years and are (slowly) progressive. Symptomatic patients have an increased risk for dependence in activities of daily living and impaired quality of life. Currently, disease-modifying therapies are not available for patients with Fahr's disease or syndrome. However, in a small case series it was shown that alendronate was effective in the clinical treatment of several patients with Fahr's disease or syndrome. Now the time has come to investigate the effectiveness of treatment with bisphosphonates in patients with Fahr's disease or syndrome in a randomized controlled trial.
