【摘要】 目的 探讨无症状性脑梗塞(ACI)的影像学改变与临床表现。方法 对1999～2003年有短暂性脑缺血发作(TIA)史或有眩晕、头痛而无明确卒中史的180例60岁以上的老年人做了CT或MRI检查，并对43例影像检查有ACI者做了简易智能状态检查(MMSE)和老年认知功能测验。结果 做CT检查的110例老年人显示有ACI者18例(占16.36%)，做MRI检查的70例显示有ACI者25例(占35.71%);43例有ACI者中有38例的心理学测验得分均低于非ACI者。结论 ACI并非无临床症状，只是症状轻微、短暂或者没有经过仔细、敏感的量化检而被忽略，最终将演变成血管性痴呆。

    【Abstract】 Objective To investigate imaging changes and clinical manifestations of asymptomatic cerebral inˉfarction.Methods CT or MRI was done in180cases of over60y patients from1999to2003.MMSE and cognitive meaˉsurement were done in43cases with ACI by imagery.Results ACI was revealed in18(16.38%)of110patients underˉwent CT and in25(35.71%)of70cases received MRI.Psychological measurement score was lower in38of the43ACI cases than that in non-ACI cases.Conclusion ACI presents slight and transient clinical manifestations and may deteriˉorate to vascular dementia if beneglected unless careful ......
