[An unusual case of transient loss of consciousness: the Fahr's syndrome].

A 69-year-old male was admitted to our Division because of repeated episodes of transient loss of consciousness and minimal cognitive and behavioural disturbances. Brain CT showed Fahr-type bilateral calcifications. Laboratory findings showed a phospho-calcium metabolism disorder consistent with the diagnosis of pseudohypoparathyroidism, whose correction led to a significant clinical improvement. This is the first case of Fahr's syndrome associated with syncope-type episodes. This observation suggests that a brain CT, as well as the search for a dysparathyroidism condition, should always carried out in all patients with unexplained recurrent episodes of loss of consciousness.
