Overview

Atrial fibrillation independently increases the risk of dementia, but early rhythm control with catheter ablation may significantly reduce the risk of cognitive decline compared to rate control.

Key Points

  • Assess the mechanisms that connect atrial fibrillation to cognitive decline and dementia.
  • Conducted a systematic review of longitudinal studies and randomized trials from the last five years.
  • Analyzed neuroimaging studies published between 2013 and 2026.
  • Examined neurocognitive variables associated with atrial fibrillation using PubMed and Cochrane database.
  • Patients with atrial fibrillation are 1.4 to 2.2 times more likely to develop dementia, independent of thromboembolic events.
  • 40% of patients with atrial fibrillation have silent cerebral infarcts.
  • Early rhythm control via catheter ablation leads to a 27% to 30% lower risk of cognitive dysfunction compared to rate control.
