TL;DR
A collaborative reanalysis of nine population-based studies conducted in Europe to compare dementia cases and noncases in risk of and time to death and to institutionalization finds prevalent cases had over twice the risk of death compared to noncases and survival for men with dementia was consistently lower than that for women with dementia of the same age group.
Abstract
The authors pooled four population-based European studies to determine the risk for institutionalization and death after stroke. Risk for institutionalization was assessed in 13,095 subjects. Survival was calculated for prevalent stroke in 7929 individuals and incident stroke in 8550 individuals. The adjusted risk of long-term care for cases compared to noncases was 2.8 (95% CI 2.6 to 4.5). At 5 years, the excess risk of death in prevalent cases was 1.6 (1.2 to 2.0), and the age- and sex-adjusted survival rate was 0.87 compared to 0.91 in noncases. The 5-year survival rate for incident cases was 0.84.
