Fahr's disease with an initial presentation of crescendo TIA.A 51-year-old man presented with vertigo, slurred speech and left facial droop.  The imaging was pathognomonic for Fahr's disease and diagnosis was confirmed when other secondary causes of hypercalcemia were excluded.  Fahr's disease is a rare, autosomal dominant, neurological condition characterised by primary brain calcification.  This case supports a growing body of anecdotal evidence of this association and is the first in which crescendo TIA may be the initial presentation of Fahr's disease.
