Blood Thinner May Slow Cognitive Decline in Alzheimer’s Patients With AFib

A recent study suggests that newer blood thinners, called NOACs, may slow cognitive decline in individuals with Alzheimer's disease and atrial fibrillation (AFib). AFib patients are at risk for brain damage from silent strokes, which can accelerate cognitive decline. NOACs are safer and more predictable than older blood thinners like warfarin.
The research, published in the European Heart Journal, analyzed data from over 7,300 Swedish patients with Alzheimer's and AFib. NOAC users demonstrated a slower rate of cognitive decline compared to warfarin users and those not taking blood thinners. While both NOAC and warfarin users had lower stroke and death risks compared to non-users, NOACs did not increase the risk of major bleeding.
The study's lead author, Maria Eriksdotter, suggests that NOACs may provide cognitive benefits beyond stroke prevention.
