众所周知,短暂完全性遗忘(TGA)是一种通常持续时间不超过24小时的记忆障碍.迄今为止,对该综合征的发病机制尚未阐明.本文研究了(1979～1985)作者所在科内所有5500例病例中的33例(女性21例,男性12例,年龄为21～73岁,平均58岁).病人有近期头外伤、癫痫、中毒和代谢性脑病及精神疾病的都不包括在内.在33例中有20例(60.6%)病史中有心血管病的危险因子,这些病人中4例以前曾有TGA发作,5例有头痛,1例有过中风.在17例中有下述诱发因素:8例是急性的情绪改变、5例急性疼痛、2例轻度外伤、2例洗热水浴.神经系统检查常在发作后不久施行,均为正常.在发作后平均二天予脑电图检查,30例正常,2例弥漫性慢波,1例双颞叶慢波.颈动脉多普勒(持续波)检查仅1例异常.26例病人做了CT扫描,4例有轻度的弥漫性萎缩,2例顶叶有局灶的低密度影,其 It is well-known that transient complete forgetfulness (TGA) is a memory disorder that lasts for up to 24 hours, and so far the pathogenesis of this syndrome has not been elucidated.This paper studies all 5500 (1979-1985) Thirty-three cases (21 women and 12 men, aged 21-73 years, mean 58 years) were excluded from recent head injury, epilepsy, poisoning and metabolic encephalopathy and mental illness.

In 17 patients, the following were induced Factors: 8 cases of acute mood changes, 5 cases of acute pain, 2 cases of mild trauma, 2 cases of hot water bath .Nervous system examination often performed soon after the onset, are normal .After the onset of an average of two days to EEG In the examination, 30 cases were normal, 2 cases were diffuse slow wave, 1 case was bilateral temporal lobe and slow wave.The carotid artery Doppler (continuous wave) examination was abnormal in 1 case, 26 cases had CT scan and 4 cases had mild Of the diffuse atrophy, 2 cases of parietal lobe focal low density, its
