EfFect of Ablation of Persistent AtriaL Fibrillation on COgNitive Function in Individuals With Mild Cognitive Impairment

This study is investigating whether treating persistent atrial fibrillation (an irregular heart rhythm) with catheter ablation — a procedure that uses energy to correct abnormal electrical signals in the heart — can slow or improve mild cognitive decline. Both atrial fibrillation and mild cognitive impairment (MCI) are common in older adults, and researchers believe the two may be linked. **You may be eligible if...** - You are between 60 and 80 years old - You have persistent atrial fibrillation and your doctor recommends restoring normal heart rhythm - You have mild cognitive impairment (MCI) based on a standardized memory test score between 18 and 25 - You are covered by French national health insurance **You may NOT be eligible if...** - You have had a clinical stroke - You have been diagnosed with or suspected to have a neurodegenerative disease (like Alzheimer's or Parkinson's), severe depression, bipolar disorder, or schizophrenia - You have previously had atrial fibrillation ablation - You have significant hearing loss, language problems, or other barriers preventing neuropsychological testing - You have a contraindication to ablation or anticoagulation Talk to your doctor to see if this trial is right for you.
