"There is a lot of brain damage in patients with atrial fibrillation, if you systematically look for it," said Dr David Conen of the University Hospital Basel, in Switzerland, and McMaster University, in Canada.

"Physicians should do whatever they can to prevent this damage from occurring, either through risk factor control or oral anticoagulation (if indicated)."
