Age as a state of mind is not just the stuff of birthday card clichés. In recent years, scientists have plumbed the molecular depths of the body and surfaced with tell-tale biomarkers of aging, some of which extend to the brain. Now, researchers are harnessing another tool, neuroimaging, to measure the organ’s age, and using that to predict how long a person will live.
“People are searching for the tree rings of humans,” James Cole, a research associate at Imperial College London, told The Scientist.
Cole and his colleagues recently devised their own technique of predicting the biological age of people’s brains using a combination of machine learning and magnetic resonance imaging (MRI) scans. In a study published last month (April 25) in Molecular Psychiatry, ...
