How old is your brain, really? AI-powered analysis accurately reflects risk of cognitive decline and Alzheimer’s disease

The human brain holds many clues about a person’s long-term health—in fact, research shows that a person’s brain age is a more useful and accurate predictor of health risks and future disease than their birthdate. Now, a new artificial intelligence (AI) model that analyzes magnetic resonance imaging (MRI) brain scans developed by USC researchers could be used to accurately capture cognitive decline linked to neurodegenerative diseases like Alzheimer’s much earlier than previous methods.
