Abstract: Subcortical ischemic vascular dementia (SIVD) is a subtype of vascular cognitive impairment. The syndrome is defined clinically by cognitive impairment and evidence of subcortical cerebral ischemia. SIVD has been recognized as lacunar state, strategic infarct dementia, and Binswanger syndrome. Prominent dysexecutive syndrome, slightly decreased working memory, and impairment of abstract reasoning are associated with lacunes and deep white matter changes. High priority should be given to reducing vascular risk profiles for prevention of SIVD.

Key words: Dementia; vascular; Brain ischemia

摘要： 皮层下缺血性血管性痴呆（subcortical ischemic vascular dementia, SIVD）是血管性认知障碍（Vascular cognitive impairment, VCI）的一个亚型，具有认知障碍和皮层下脑缺血病灶的证据。其包括腔隙状态、关键部位梗死性痴呆和Binswanger综合征等3个类型。认知障碍的特征是显著的执行功能障碍和相对轻微的工作记忆减退。对脑血管病危险因素的干预有助于皮层下缺血性血管性痴呆的防治。
