[背景]探讨短暂性全面性遗忘症(TGA)的病因及临床特点.[病例报告]给7例诊断为TGA的患者行脑电图、头颅CT或MRI及颈部血管彩色多普勒超声波检查.7例中合并高血压5例,血脂异常4例,血糖异常1例,颈部动脉粥样斑块形成5例.脑电图检查结果显示,4例未见异常,3例可见少量慢波;头颅CT或MRI检查结果显示,5例腔隙性脑梗塞,2例未见异常.[讨论]TGA患者均有不同程度脑缺血改变,认为TGA发作可能与脑缺血有关联.
[Background] To investigate the etiology and clinical features of transient total amnesia (TGA). [Case Report] Seven patients with TGA were examined by EEG, CT or MRI, and color Doppler ultrasonography .7 cases with hypertension in 5 cases, 4 cases of dyslipidemia, 1 case of abnormal blood glucose, neck atheromatous plaque formation in 5. EEG examination results showed that 4 cases showed no abnormalities, 3 cases showed a small amount of slow wave ; Cranial CT or MRI examination showed that 5 cases of lacunar infarction, 2 cases no abnormalities. [Discussion] TGA patients with varying degrees of cerebral ischemia, that TGA attack may be associated with cerebral ischemia.
