Researchers Call for Personalized Approach to Aging Brain Health

People are living longer than ever before, but brain health isn't keeping up. To tackle this critical problem, a team of researchers has proposed a new model for studying age-related cognitive decline – one that's tailored to the individual.

There's no such thing as a one-size-fits-all approach to aging brain health, says Lee Ryan, professor and head of the University of Arizona Department of Psychology. A number of studies have looked at individual risk factors that may contribute to cognitive decline with age, such as chronic stress and cardiovascular disease. However, those factors may affect different people in different ways depending on other variables, such as genetics and lifestyle, Ryan says.

In a new paper published in the journal Frontiers in Aging Neuroscience, Ryan and her co-authors advocate for a more personalized approach, borrowing principles of precision medicine in an effort to better understand, prevent and treat age-related cognitive decline.

"Aging is incredibly complex, and most of the research out there was focusing on one aspect of aging at a time," Ryan said. "What we're trying to do is take the basic concepts of precision medicine and apply them to understanding aging and the aging brain. Everybody is different and there are different trajectories. Everyone has different risk factors and different environmental contexts, and layered on top of that are individual differences in genetics. You have to really pull all of those things together to predict who is going to age which way. There's not just one way of aging."
