Washington, June 8: Researchers found the amount of fat in the body s muscle, or muscle adiposity, may predict a person s risk of cognitive decline as they age. A 5-year increase in fat stored in the thigh muscle was found to be a risk factor for cognitive decline in a study published in the Journal of the American Geriatrics Society. This risk was unrelated to the total weight, other fat deposits, muscle characteristics (such as muscle strength or mass), and traditional dementia risk factors.
