The physicians tied a specific type of body fat, known as visceral fat, to higher levels of abnormal proteins in the brain that are indicators of Alzheimer’s. Visceral fat builds up around and between internal organs and can increase the risk of serious health issues. It is different than subcutaneous fat, which is fat just below the skin.

A specific type of body fat that surrounds vital organs in middle age could be linked to abnormal proteins in the brain that are the hallmarks of the most common cause of dementia

Decades before the first signs of memory loss appear, a hidden type of body fat might be signaling the early stages of Alzheimer's disease.

Researchers have discovered that Alzheimer's disease could be detected up to 20 years before the earliest symptoms appear, following a major scientific breakthrough.

People who are obese and harbor deep belly fat are at higher risk for developing Alzheimer's disease-specific proteins in the brain up to 20 years before the earliest dementia symptoms, a new study suggests.

The brain cells, or neurons, also showed signs of recovery, the scientists reported in Nature Neuroscience. This discovery suggested that blocking TYK2 could be a way to reduce the toxic tau buildup, and the damage it causes in diseases like Alzheimer’s.

Researchers have linked a specific type of body fat to the abnormal proteins in the brain that are hallmarks of Alzheimer's disease up to 20 years before the earliest symptoms of dementia  appear, according to a study being presented today at the annual meeting of the Radiological Society of North America (RSNA).
