This study examined the risk of first\u2010time stroke among older adults with lower cognitive function in different cognitive domains and how associations vary by age.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p xml:lang=\"en\">This longitudinal cohort study used baseline data from G\u00c5S (Good Aging in Sk\u00e5ne) and registry data from the Swedish Board of Health and Welfare. Exclusion criteria were previous stroke or transient ischemic attack, baseline dementia, or no cognitive data. The participants (n=4912) were divided into tertiles on the basis of performance on cognitive tests representing multiple cognitive domains. Cox regression was used to estimate the risk of stroke for the low tertile of cognitive function compared with the high tertile. Age\u2010stratified analysis was performed for participants aged 60 to 69, 70 to 79, and \u226580\u2009years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">The studied population consisted of 2203 men, 3094 aged 60 to 69\u2009years, 494 aged 70 to 79\u2009years, and 1184 aged \u226580\u2009years. During the average follow\u2010up time of 12.3\u2009years, 572 of the 4912 participants had a stroke. In the fully adjusted models, participants in the low tertile of perceptual speed had higher risk of stroke (hazard ratio [HR], 1.40 [95% CI, 1.13\u20131.72]). In age\u2010stratified analysis, higher risk of stroke was observed for participants aged 60 to 69\u2009years in the low tertile of global cognition (HR, 1.86 [95% CI, 1.27\u20132.69]), episodic memory (HR, 1.68 [95% CI, 1.21\u20132.33]), and perceptual speed (HR, 1.66 [95% CI, 1.19\u20132.32]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n
