Brain scan measures aging rate

Brain scan measures aging rate
NIH News in Health; 9/8/25
Biologically speaking, some people age faster than others. Your aging rate can affect your health and disease risks. If you knew this rate, you might be able to work with your doctor to slow the aging process. A [Duke University] research team developed a way to measure aging based on a single brain scan. The team drew on their earlier studies, where they devised a way to measure biological aging using blood tests [and] combined scores with MRI scan data... [Results] accurately predicted how quickly a person’s ability to think and remember weakened with age. It also could predict a person’s risk of future disease and death.
Publisher's note: I wonder if this tool might someday be incorporated into hospice eligibility/prognosis criteria?
