摘要

短暂性全全性遗忘(TGA)是一种严重的记忆障碍,发生迅速,持续时间不超过一天,主要影响老年人。急性期表现为严重的顺行性失忆、部分逆行性失忆和反复思考相同问题的焦虑。诊断纯粹是根据病人的临床特征。只有在出现非典型症状时才要求进行补充检查。TGA的病理生理机制尚不清楚,但它似乎与海马结构灌注和氧合的短暂紊乱有关,在一个诱发因素(压力、努力等)之后。自发恢复通常在24小时内,无后遗症。复发是罕见的。然而,TGA对患者及其家属来说是一种心理创伤病理学。

[Idiopathic transient global amnesia].

Transient global amnesia (TGA) is characterized by a severe disturbance of memory, occurring rapidly, lasting less than a day and mainly affecting elderly subjects. During its acute phase, it is characterized by a severe anterograde amnesia, partial retrograde amnesia and anxiety with repetition of the same questions. The diagnosis is purely based on patient's clinical features. Complimentary examinations are only requested when atypical symptoms are present. The pathophysiology of TGA remains unknown, but it appears to be related to transient disturbances of the perfusion and oxygenation of the hippocampal structures, following a precipitating factor (stress, effort...). Spontaneous recovery is usual in less than 24 hours and without sequelae. Relapse is rare. Nevertheless, TGA represents a psychological traumatism pathology for the patients and their family.
