Brain Aging
Your Brain Believes What You Tell It About Getting Older
One of the most consistent findings in brain health research is that our brains and by extension their health are majorly impacted by our lives. The brain is exquisitely sensitive to its environment, what you eat, how you sleep, how much you move, how stressed you are. But a compelling and underappreciated line of research is now asking a different kind of question: what about what you believe? Specifically, could your brain beliefs change how it ages?
A new study published in Geriatrics in 2026 by Yale researchers Becca Levy and Martin Slade offers some of the strongest evidence yet that the answer matters more than most people realize and that the dominant cultural narrative about brain aging may itself be a risk factor.
