Dementia in Stroke Survivors
Cerebrovascular disease has been considered the second most common cause of dementia. As many as 20%–25% of cases of dementia are due to stroke; another 10%–15% are attributed to a combination of vascular and Alzheimer’s disease. Although cerebral arteriosclerosis itself is not thought to play a causal role in Alzheimer’s disease, there is still controversy about the role of ischemic stroke in producing global cognitive disorders classifiable as dementia. The true risk of dementia posed by ischemic stroke is not known because most prior studies focused on series of selected or consecutively encountered patients with dementia, rather than assessing dementia in stroke cohorts.
