Poststroke dementia predicts poor survival in long-term follow-up: influence of prestroke cognitive decline and previous stroke

Abstract

Long-term follow-up of our large well-defined poststroke cohort indicated that in patients with acute stroke, dementia is a significant predictor of poor long-term survival and death from brain-associated causes. Prestroke cognitive decline seems to have an additional negative influence on survival, but previous stroke does not seem to affect survival.
