Background: Depression is a risk factor for stroke and mortality but whether this also holds into old age is uncertain. We therefore studied the association of depression with the risk for non-fatal stroke and all-cause mortality in very old age. %26lt;br%26gt;Methods: A representative sample of 3085 primary care patients aged %26gt;= 75 years were serially assessed during a 6-year follow-up. The relation between depression (Geriatric Depression Scale %26gt;6, n=261) and relevant covariates including vascular risk factors and disease, functional and mild cognitive impairment and ApoE genotype on primary care givers information of incident stroke (n=209) and mortality (n=647) were assessed by Cox regression and by competing risk regressions. %26lt;br%26gt;Results: Depression was not independently associated with incident stroke in fully adjusted models that treated death as the competing event (subdistribution hazard ratio=0.80, 95% confidence interval =0.47 to 1.36). The risk associated with depression was similar for men and women, and for age groups 75-79, 80-84 and %26gt;= 85 years. In contrast, depression increased all-cause mortality rates, even after adjusting for a range of confounders (hazard ratio =1.31, 95% confidence interval =1.03 to 1.67). %26lt;br%26gt;Limitations: We have no information on past depressive episodes and cause of death. %26lt;br%26gt;Conclusions: In contrast to reports in younger populations, depression does not appear to increase stroke risk among the old and very old, but continuous to be a risk factor for all-cause mortality.
