Scientists are uncovering promising ways to track and improve brain health as we get older—think better diet, exercise, and proactive habits—instead of just treating problems after they arise. It’s not about miracle cures, but small, measurable steps that could add up to sharper minds later in life.

Editor’s Note: Forget the old idea that mental decline is inevitable. This research flips the script, showing we might have more control over our brain’s aging process than we thought. It’s a hopeful shift—not just for individuals, but for public health strategies aiming to keep people independent and engaged longer.
