Can a single brain scan reveal how fast you're aging — and predict your risk of dementia years before symptoms appear? Researchers from Duke, Harvard, and the University of Otago, New Zealand, have developed DunedinPACNI, a machine learning tool trained on one of the most detailed aging studies in the world. Using MRI data from the Dunedin Study, this tool estimates the rate of brain aging and the likelihood of future cognitive decline, offering new hope for early detection and prevention. Learn how lifelong data and cutting-edge neuroscience are helping scientists forecast health risks before it's too late.
