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
