Abstract

Transient global amnesia (TGA) is an isolated amnesic syndrome with normal neurologic examination. Patients remain alert and communicative with no loss of personal identity; however, they experience striking loss of memory for recent events and an impaired ability to retain new information. We report a case of TGA in a patient with acute ischemia in bilateral hippocampal abnormalities. This provides evidence in support of an ischemic hypothesis as the possible etiology of TGA.

摘要

短暂性全面遗忘症（TGA）是一种孤立的遗忘综合征，神经检查正常。患者保持警觉和沟通，没有个人身份丧失；然而，他们经历了对近期事件的惊人记忆丧失和新信息的保留能力受损。我们报告了一例双侧海马异常急性缺血患者的 TGA 病例。这为 TGA 的可能病因即缺血假说提供了证据支持。
