Sean Connery, who just recently died had AF, he also had alzimers. Lots of famous people seem to have AF, wonder if AF contributes to Alzimers. Perhaps it would depend on how long you have AF, my mother died at 92 and she had persistent AF for about 7 years, but she was sound of mind, it was her heart.

Anticoagulation = lower risk

Warfarin = higher risk

"Atrial fibrillation can increase the risk of dementia because it exposes patients to both large and small clots that can affect brain function. Blood thinners used to prevent all forms of clots and strokes can increase the risk of both large and small brain bleeds that can also negatively impact brain function over time."
