CHICAGO, Nov. 20, 2023 - Higher amounts of visceral abdominal fat in midlife are linked to the development of Alzheimer’s disease, according to research being presented next week at the annual meeting of the Radiological Society of North America (RSNA). Visceral fat is fat surrounding the internal organs deep in the belly. Researchers found that this hidden abdominal fat is related to changes in the brain up to 15 years before the earliest memory loss symptoms of Alzheimer’s disease occur.
