People with a brain age older than their bodies could be at greater risk of dying early, according to a recent study. Dr. James Cole, a neuroscientist at Imperial College London, led a research project using MRI scans and a computer program to predict a person’s brain age. The system, which is still in development, could help spot people whose lifestyles put them at greater risk of poor health and early death. LLAMA host Peter Bowes visited Hammersmith Hospital in London for this in-depth interview with Dr. Cole, who explains how data for the study was collected and how the findings could be used to help people live longer lives. He also discusses what some people call “the mosaic of aging”, the idea that different tissues and systems in the body can age at a different pace.
