Scientists can tell how fast you’re aging from a single brain scan
Can Tell How Fast You’re Aging From a Single Brain Scan New aging clock can predict risk for dementia, other age-related diseases years before symptoms appear Several algorithms have been developed to measure how well a person is aging. But most of these “aging clocks” rely on data collected from people of different ages at a single point in time, rather than following the same individuals as they grow older, Hariri said.
Every few years, Dunedin Study researchers looked for changes in the participants’ blood pressure, body mass index, glucose and cholesterol levels, lung and kidney function, and other measures — even gum recession and tooth decay. The correlations between aging speed and dementia were just as strong in other demographic and socioeconomic groups than the ones the model was trained on, including a sample of people from Latin America, as well as United Kingdom participants who were low-income or non-white.
