Even if you can’t see it, fat buried deep within the belly can increase the risk of Alzheimer’s disease.That’s according to research released by the Radiological Society of North America (RSNA) on Monday.Visceral fat, which surrounds the internal organs in the belly, has been linked to brain changes that could point to future dementia in people as young as 50, up to 15 years before symptoms appear, as noted in a press release from RSNA.BOOST BRAIN HEALTH AND SLOW MENTAL AGING WITH 10 INTRIGUING TIPS FROM LONGEVITY EXPERTSThe findings, published in the journal Aging and Disease, will be presented at the RSNA’s annual meeting next week.Researchers analyzed the brain MRIs and PET scans of 54 “cognitively healthy” participants between the ages of 40 and 60, focusing on any inflammation and “plaques and tangles” that are typically seen in Alzheimer’s patients. Fat buried deep within the belly can increase the risk of developing Alzheimer’s disease, according to research released by the Radiological Society of North America (RSNA).

THE 8 BIGGEST ALZHEIMER’S DISEASE MYTHS — AND THE TRUTHS BEHIND THEM”Similar studies have not investigated the differential role of visceral and subcutaneous fat, especially in terms of Alzheimer’s amyloid pathology, as early as midlife.”The researchers found that those with more visceral fat also had higher levels of amyloid in the precuneus cortex, which is the region of the brain that usually shows the earliest signs of Alzheimer’s disease. They also had greater inflammation in the brain. Before this research, no prior study has linked a specific type of fat to the actual Alzheimer’s disease protein in cognitively normal people.

More than six million Americans are living with Alzheimer’s disease, according to the Alzheimer’s Association.

This number is expected to approach 13 million by 2050. One in every five women and one out of 10 men will develop the common form of dementia in their lifetime.For more Health articles, visit www.foxnews.com/health.
