As our nation ages, the prevalence of both atrial fibrillation (AF) and dementia are rising. Ten percent of the nearly 3 million people in the US affected by AF are over the age of 80.¹ Conventionally, it's been easy to appreciate a pathway from AF to dementia involving clinically significant strokes damaging areas of the brain responsible for cognition. However, recent studies have suggested that AF itself is a risk factor for dementia even in the absence of clinical stroke.^2-6 One meta-analysis of seven prospective trials found an odds ratio of 1.6 for the association between AF and dementia. Many of the individual studies had important methodologic limitations,⁷ however, such as small sample size leading to underpowering, short follow-up, unadjudicated identification of dementia, and AF diagnoses established only at baseline.

Rest at link and your doctor knows all about it anyway. Who, me worry?
You already put your stroke recovery in your doctors hands and that worked perfectly, didn't it?  This has been known since 1997
