A 51-year-old man presented with vertigo, slurred speech and left facial droop. He had been previously diagnosed with transient ischaemic attack (TIA) and had a prior lacunar infarct. Imaging showed heavy symmetrical calcification in the globus pallidus, frontal white matter and cerebellar dentate nuclei/deep white matter. 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. Patients present with progressive neurological and psychiatric symptoms; commonly, Parkinsonian movement disorders, seizures, headaches, dysarthria, cognitive decline, psychosis and personality changes. There is an association with intracerebral ischaemic events. 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. Referral for genetic counselling and symptomatic relief for neurological symptoms are the main management strategies.© BMJ Publishing Group Limited 2021. No commercial re-use.
