Multicenter Study
Oral anticoagulant and reduced risk of dementia in patients with atrial fibrillation: A population-based cohort study.
Whether oral anticoagulation (OAC) can prevent dementia or cognitive impairment (CI) in patients with atrial fibrillation (AF) remains unclear. ⋯ OAC use was associated with a lower risk of dementia/CI compared to non-OAC and antiplatelet treatment among AF patients. The evidence for DOAC on cognitive function is insufficient, and further studies including randomized clinical trials are warranted.
