A new tool can now estimate how fast a person is aging. 

University of Otago scientists have found a way to use an MRI scan of the brain to quantify the rate of biological aging of middle-aged people to forecast risks of dementia, chronic disease, and death in older adulthood. 

The technology was developed using data from the Dunedin Study, a decades long health project tracking more than 1,000 people born in the early 70’s. 

Dunedin Study director Professor Moana Theodore joined Kerre Woodham to break down the findings of the study and how the tool works.
