目的 :探讨无症状性脑梗死 ( ACI)与脑血管性痴呆 ( VD)的关系。方法 :采用病例对照的方法对 62例脑血管性痴呆患者和 62名正常老年人进行 CT或 MRI检查 ,比较两组 ACI的发生情况。结果 :62例正常老年人中发现 ACI 1 1例 ( 1 7.7% ) ,62例 VD中发现 ACI 32例 ( 51 .6% ) ,显著高于正常组 ( P<0 .0 0 5)。结论 :ACI与 VD密切相关。
Objective: To investigate the relationship between asymptomatic cerebral infarction (ACI) and cerebrovascular dementia (VD). Methods: Sixty-two patients with cerebrovascular dementia and 62 normal controls were examined by CT or MRI using the case-control method. The incidence of ACI in both groups was compared. Results: Among the 62 normal controls, ACI was found in 11 (7.7%) of 32 normal controls and 32 (51.6%) were found in 62 of VD, which was significantly higher than that of normal control (P <0.05). Conclusion: ACI is closely related to VD.
