Time\u2010to\u2010event (dementia or subtypes) analyses were performed using Cox proportional hazards and weighted Cox. Sub\u2010analyses performed: including &amp; censoring stroke and age (median used as cut\u2010off).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Over a median follow\u2010up of 2.67\u2009years (IQR .65\u20136.02) for AF patients and 5.84\u2009years for non\u2010AF patients (IQR 2.26\u201311.80), incidence of dementia in the AF cohort was 2.65 per 100 person\u2010years, compared to 2.02 in the non\u2010AF cohort. After adjustment, a significant association was observed between AF and all\u2010cause dementia (HR\u2009=\u20091.38, 95% CI: 1.31\u20131.45), driven by a strong association with VaD (HR\u2009=\u20091.55, 95% CI: 1.41\u20131.70). AF was also associated with mixed dementia (HR\u2009=\u20091.26, 95% CI: 1.01\u20131.56), but we could not confirm an association with Alzheimer (HR\u2009=\u20091.05, 95% CI: .94\u20131.16) and rare dementia forms (HR\u2009=\u20091.19, 95% CI: .90\u20131.56). Ischemic stroke (HR\u2009=\u20091.40, 95% CI: 1.26\u20131.56), subarachnoid haemorrhage (HR\u2009=\u20092.08, 95% CI: 1.47\u20132.96), intracerebral haemorrhage (HR\u2009=\u20091.95, 95% CI: 1.54\u20132.48) and diabetes (HR\u2009=\u20091.32, 95% CI: 1.24\u20131.41) were identified as the strongest predictors of dementia in AF patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>AF patients have an increased risk of dementia, independent of stroke, with highest risk of VaD.
