The secrets to keeping your brain sharp in old age
Neuroscientist Emily Rogalski is uncovering the secrets of superagers Craig Boylan As you age, your memory will likely decline. Your ability to recall where you parked the car or the name of your first teacher will be less sharp in your 80s than in your 50s, if you’re in the majority of people. But a small pool of individuals in their 80s and beyond don’t experience this downturn: they have a memory that rivals that of people decades younger. It is this group that Emily Rogalski is interested in. Rogalski, a neuroscientist at the University of Chicago and head of the ongoing superager study, is unpicking how these people manage to stay so sharp, even if they have signs of Alzheimer’s disease in their brain. Rogalski and her colleagues have already shown that so-called superagers have larger cerebral cortices and hippocampi, both areas of the brain associated with memory, and are now working to unravel the neural basis of their recall abilities. She tells New Scientist what makes someone a superager, and how you can …
