摘　　要：目的探讨短暂性全面性遗忘(TGA)的临床特点。方法回顾性分析14例TGA患者的临床资料。结果本组患者男女各为7例,年龄52～70岁;5例因情绪激动、4例因"受凉"、2例因劳累发病。临床表现为突然出现的顺行及逆行遗忘,持续时间0.5～15h,6例伴有头痛或头晕;体检无阳性体征发现;头颅MRI示4例海马区DWI小灶高信号。结论 TGA临床特征为一过性记忆障碍,情绪激动为主要发病诱因,DWI高信号可能与静脉充盈有关。Objective To explore the clinical features of transient global amnesia （TGA）.Methods The clinical data of 14 TGA patients were analyzed retrospectively.Results The 14 TGA patients included 7 male and 7 female,with the age between 52-70 years old. The motivation in 5 cases was agitation,in 4 cases was catch cold and in 2 cases was exertion. The clinical manifestations were emergent anterograde and retrograde amnesia with the duration of 0.5-15 h. 6 cases had other symptoms such as headAChE or dizziness. No positive focal sign was found out in physical examination. The skull MRI showed that there were small and high DWI signals in hippocampus in 4 cases.Conclusions The clinical feature of TGA is transient memory disorder. The agitation is the major induced motivation. The high DWI signals may be related with venous congestion.
