University of Minnesota Medical School researchers have determined that atrial fibrillation (Afib) is independently associated with changes that occur with aging and dementia.
“Atrial Fibrillation and Brain Magnetic Resonance Imaging Abnormalities” published in Stroke advances researchers’ understanding of the mechanisms underlying atrial fibrillation-related dementia. Jeremy Berman, a University of Minnesota cardiology fellow is the first author of this paper. It had already been determined that Afib is associated with dementia independent of clinical stroke but the mechanisms surrounding the association were still unclear.
“Until this point, most studies which looked into this association were cross-sectional, which have limitations,” said Lin Yee Chen, MD, MS, Associate Professor with tenure, Cardiovascular Division, in the Department of Medicine with the University of Minnesota Medical School. “In our study, brain MRI scans were performed at two different times within ten years.”
