Life expectancy and dementia in Canada: the Canadian study of health and aging.

Abstract

Using the 1991 Canadian life table and estimates of the prevalence of dementia from the Canadian Study of Health and Aging, we have partitioned the expectation of life at age 65 into years spent in the community and in institutions, with and without different forms of dementia. The total expectation of life for women was 26% greater than that for men, but women's expectations of life with dementia and of life in institutions were more than twice the corresponding expectations for men. The difference between sexes was greater for Alzheimer's disease than for vascular and other types of dementia.
