Transient global amnesia: A review of the recent literature

Simons, J.S. and Hodges, J.R. (2000). Neurocase, 6, 211-230.

Transient global amnesia (TGA) is a syndrome associated with abrupt, isolated episodes of severe anterograde amnesia and disorientation. Although the first case of TGA was described in the 1950s, the intervening decades have seen numerous further reports that have refined the clinical picture of the disorder and have used TGA to investigate theories concerning the organisation of human long-term memory processes. This review outlines recent advances in our understanding of the neuropsychology, aetiology, and neuroradiology of TGA and demonstrates that, despite the considerable amount of research recently undertaken, the syndrome still remains rather an enigma.
