A commonly prescribed class of blood-thinning medicines may do more than prevent strokes in people living with both atrial fibrillation and Alzheimer’s disease. Even without a major, recognizable stroke, however, atrial fibrillation may be associated with repeated tiny disruptions in cerebral blood flow. Researchers identified 7,308 people diagnosed with both Alzheimer’s disease and atrial fibrillation and compared their outcomes according to anticoagulant treatment. Atrial fibrillation, high blood pressure, diabetes and other vascular conditions can place additional stress on this system.
