We studied the clinical characteristics of transient global amnesia (TGA) in 277 patients with an average follow-up of 80 months. The syndrome occurred most frequently after age 50. There was a history of migraine in 14.1% and cerebrovascular diseases in 11.2% of patients, but these conditions were usually not temporally linked to TGA. Characteristic antecedent events and activity such as exertion existed in 33.4%. The incidence of TGA was 5.2 per 100,000 per year in Rochester, MN. Although 23.8% of the patients had recurrent episodes, they were not at increased risk for subsequent stroke.
我们研究了277例短暂性全面性遗忘症（TGA）患者的临床特征，平均随访时间为80个月。该综合征最常发生在50岁以后。14.1%的患者有偏头痛病史，11.2%的患者有脑血管疾病史，但这些情况通常与TGA无时间关联。33.4%的患者存在如劳累等典型的前驱事件和活动。在明尼苏达州罗切斯特市，TGA的发病率为每年每10万人中有5.2例。虽然23.8%的患者有复发发作，但他们随后发生中风的风险并未增加。
