Atrial Fibrillation Associated with Reduced Frontal Lobe Volume

It is well established that Atrial Fibrillation (AF), a common heart arrhythmia, is associated with an increased risk of stroke and cognitive decline. However, the impact of AF on brain structure has not been properly studied. According to a recent Framingham Heart Study, people who experience AF, may also suffer from a smaller brain, specifically reduced frontal lobe volume.

Rhoda Au, PhD, Professor of Anatomy, Neurobiology, Neurology and Epidemiology at Boston University Schools of Medicine (BUSM) and Public Health (BUSPH), used magnetic resonance imaging (MRI) to look at the relationship between AF and brain volume.
