Trial of Apixaban vs Warfarin in Reducing Rate of Cognitive Decline, Silent Cerebral Infarcts and Cerebral Microbleeds in Patients With Atrial Fibrillation
ARISTA

Brief Summary
The investigators' central hypothesis is that in patients with atrial fibrillation, anticoagulation with Apixaban reduces the rate of decline in cognitive function, when compared to Warfarin. The investigators also hypothesize that Apixaban reduces cognitive decline by reducing the rate of new cerebral infarction and cerebral microbleeds detected by cerebral MRI compared to warfarin.
