A new study presented at the Radiological Society of North America annual meeting explored the link between obesity and the development of Alzheimer’s.

In the latest Alzheimer’s research, hidden fat in various parts of the body was shown to be an early warning sign of the common dementia — as much as 20 years before symptoms emerged.

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.

Buildup of this visceral fat in middle age may boost levels of the two damaging brain proteins, called amyloid and tau, explained a team led by Dr. Mahsa Dolatshahi, of Washington University School of Medicine in St. Louis. Actual symptoms of Alzheimer's disease may not arise until many years later.

Having belly fat during your 40s and 50s may be a sign that the brain is already becoming sick and shrinking, increasing the risk of Alzheimer’s disease later in life.

Researchers have uncovered a connection between a specific type of body fat and the abnormal brain proteins associated with Alzheimer’s.

As the size of a person’s belly grows, the memory center of their brain shrinks and beta amyloid and tau may appear — all of this occurring as early as a person’s 40s and 50s, well before any cognitive decline is apparent,

Visceral fat has been linked to early Alzheimer’s disease pathology, according to a study of midlife individuals. Researchers found this fat significantly increases amyloid and tau protein accumulation,
