Lower Cognitive Impairment / Dementia With Oral Anticoagulants For Atrial Fibrillation (European Heart Journal / NHS Choices / Neurology)

Summary

Swedish researchers have discovered that anticoagulant treatment for atrial fibrillation is associated with a 29% lower risk of dementia.

“The risk of dementia is higher without oral anticoagulant treatment in patients with AF. This suggests that early initiation of anticoagulant treatment in patients with AF could be of value in order to preserve cognitive function”.

There was apparently no difference between use of NOACs and warfarin.

October 2018 Update

A Swedish study appears to confirm that while atrial fibrillation is associated with faster cognitive decline and an increased risk of dementia in older people, the use of anticoagulant drugs (but not antiplatelets) may help reduce dementia risk.
