Hippocampal Ischemic Transient Global Amnesia after Gastrointestinal Endoscopy without Prior Medication

Abstract

Background: Transient global amnesia (TGA) is a clinically amnestic syndrome characterized by normal neurological function aside from sudden-onset, reversible anterograde amnesia during the episode. TGA is typically related to strenuous physical activity, severe emotional stress and some medical procedures, such as angiography, while reports of TGA related to gastrointestinal (GI) endoscopy are extremely rare.
