Atrial fibrillation patients aged 75 and older had an average rate of cognitive decline that was about three to four points faster every five years compared with those without the condition, according to a study in the journal Neurology. Although the findings showed no direct cause-and-effect relationship between atrial fibrillation and mental decline, lead author Evan L. Thacker said that it is possible that patients with the condition have little blood clots in the heart that would then get stuck in the brain or have smaller amounts of blood flowing to the brain.
