Is atrial fibrillation associated with a higher risk for cognitive impairment and dementia?
Atrial fibrillation is associated with an increased risk of cognitive impairment and dementia, independent of clinical stroke history.
Evidence suggests that AF is associated with a higher risk for cognitive impairment and dementia, with or without a history of clinical stroke. Further studies are required to elucidate the association between AF and subtypes of dementia as well as the cause of cognitive impairment.
Kalantarian et al. (Tue,) studied this question.
