Dementia after stroke is a predictor of long-term survival.

“…It appears that dementia of any etiology diminishes life expectancy. 25 Specifically, AD has been associated in many studies with a marked reduction in survival compared with nondemented elderly persons, 26 and in comparing AD with vascular dementia, the survival rate appears to be lower in those with a vascular basis for dementia.…”

Previous and Incident Dementia as Risk Factors for Mortality in Stroke Patients

“…[15][16][17] Dementia is a cause of morbidity/mortality in the elderly and is a risk factor for adverse outcomes; it reduces life expectancy independently of its etiology. 18,19 In a previous study, Tatemichi et al 20 demonstrated that dementia adversely influences long-term survival after stroke; however, it is unknown whether mortality is determined by dementia that precedes stroke or that appears just after it. We have examined the long-term survival of a group of consecutive nonselected stroke patients and the relationship of mortality to previous and stroke-related dementia.…”

Survival in Presenile Alzheimer's and Multi-lnfarct Dementias

“…Old people have the highest incidence of Alzheim er's disease (AD) and m ulti-infarct dem entia (M ID) [1], and most studies have concentrated on the survival o f patients with late onset or senile dem entia and not on early onset, or presenile, AD and M ID [2][3][4]. Prese nile patients, though considerably fewer, rep resent an im portant diagnostic group.…”
