Study: Atrial fibrillation associated with higher risk of dementia

Atrial fibrillation, the most common source of irregular heartbeat, is linked to an increased risk of dementia, researchers from Group Health Research Institute found. In looking only at study participants with atrial fibrillation over a seven-year period, they said individuals had a 40% to 50% higher risk of developing some form of dementia, including Alzheimer's, compared to those without atrial fibrillation.
