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,并对68例影像学检查有 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 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。
Objective To investigate the relationship between asymptomatic cerebral infarction (ACI) and vascular dementia (VD). Methods A total of 300 elderly patients over 60 years of age with a history of transient ischemic attack (TIA) or with dizziness and headache without a definite history of stroke from 1995 to 2004 were examined by CT or MRI. 68 cases of imaging examination ACI who have done a simple intelligent state examination (MMSE) and cognitive function test of the elderly. Results Of the 200 elderly people who underwent CT examination, 33 (16.5%) had ACI, 100 (100%) had ACI, and 63 (68%) had ACI Tests, scores were lower than non-ACI. Conclusion ACI is not without clinical symptoms, only mild and transient symptoms, ACI patients have different degrees of cognitive dysfunction, eventually evolving into vascular dementia.
