Newsweek (10/10, Gander) reports that researchers “have found a link between” atrial fibrillation “and the risk of developing dementia.” The findings were published in Neurology. Reuters (10/10, Carroll) reports that the investigators “found that atrial fibrillation raises the overall risk of developing dementia by 40 percent and the risk of vascular and mixed dementias by nearly 90 percent.” However, people with atrial fibrillation “who got anti-clotting drugs were 60 percent less likely than those who didn’t get the drugs to develop dementia.” (SOURCE: APA Headlines)
