【摘要】 【目的】探讨无症状性脑梗死(ACI)与血管性痴呆(VD)的关系。【方法】对1995~2004年有短暂性脑缺血发作(TIA)史或有眩晕、头痛而无明确卒中病史的300例60岁以上的老年人做了CT或MRI检查,并采用简易精神状态检查(MMSE)和临床痴呆评定(CDR)对68例影像学检查有ACI者做了老年认知功能测验。【结果】做CT检查的200例老年人显示有ACI者33例(占16.5%),做MRI检查的100例显示有ACI者35例(占35%),68例有ACI者中有63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,ACI患者绝大多数都有不同程度的认知功能障碍,最终将演变成血管性痴呆。更多还原

【Abstract】 【Objective】To study the relationship between asymptomatical cerebral infarction(ACI) and vascular dementia(VD).【Methods】CT or MRI was usee for examining 300 cases who were over 60 years old and experienced transient ischemic attack or vertigo and headache without obvious stroke from 1995 to 2004.By iconography test,68 cases of ACI were given cognitive function measurement by the Mini-Mental State Examination(MMSE) and Clinical Dementia Rating(CDR).【Results】Of 200 senile patients examined by CT,33 cases had ACI(16.5%);of 100 senile patients examined by MRI,35 cases had ACI(35%);of 68 cases with ACI,psychological measurement score of 63 cases was lower than that of cases without ACI.【Conclusion】The patients with ACI present slight and transient clinical manifestations.Most of the ACI patients have disorder of cognitive dysfunction to varying degrees and at last they will develop vascular dementia.更多还原
