The etiology of transient global amnesia is poorly understood, particularly in children and young adults. Transient global amnesia may follow a wide range of precipitating events. Proposed causes have included vascular event, seizure, and migraine. A young man with cyanotic congenital heart disease experienced an episode of transient global amnesia in the setting of polycythemia. Differential diagnosis of acute confusional episodes in children should include transient global amnesia, as well as confusional migraine, and should include evaluation for underlying coagulation abnormalities and polycythemia.

D020236	Amnesia, Transient Global	A syndrome characterized by a transient loss of the ability to form new memories. It primarily occurs in middle aged or elderly individuals, and episodes may last from minutes to hours. During the period of amnesia, immediate and recent memory abilities are impaired, but the level of consciousness and ability to perform other intellectual tasks are preserved. The condition is related to bilateral dysfunction of the medial portions of each TEMPORAL LOBE. Complete recovery normally occurs, and recurrences are unusual.
