摘　　要：目的 探讨老年人短暂性全面遗忘症(TGA)的病因。方法 汇总我院2002～2012年间共24例TGA患者的CT、MRI、血管超声、脑电图等检查资料,结合国内外相关的研究进展探讨老年TGA的病因。结果 75%的TGA患者头颅影像学有缺血性改变,50%的患者血管超声示血管狭窄或动脉斑块,33%的患者伴有糖尿病、房颤等微血栓危险因素;8例发病前有争吵、爬山、骑车、劳动等导致氧耗量增加的因素,1例伴有偏头痛。结论 TGA是一种多病因疾病,但缺血仍是老年TGA的主要病因。Objective To discuss the etiology of transient global amnesial(TGA).Methods The data of CT,MRI,vascular ultrasound,electroencephalograph of 24 elderly patients with TGA in Navy General Hospital from 2002 to 2012 were collected and analyzed in touch with the progress at home and abroad on the TGA.Results Of these TGA patients,75% presented with ischemic imaging,50% presenting with hemadostenosis or arterial plaque in blood vessel,33% presenting with risk factors of microthrombus such as diabetes mellitus,atrial fibrillation.Eight cases had factors which could increase oxygen consumption before the onset,such as quarrel,hiking,biking,labor and so on.One case suffered from migraine.Conclusions TGA is a multi-cause disease,and ischemia is the major cause of TGA in the aged.
