Study: Clues to Razor-Sharp Memory Revealed
As we get older, we accept that our memories are not what they used to be. But according to Northwestern University’s (Chicago) Emily Rogalski, an assistant research professor at the Cognitive Neurology and Alzheimer’s Disease Center, there is a group called SuperAgers who are resistant to memory loss. And now they know why.
In a study, Rogalski and her co-authors found this group may experience optimal cognitive aging due to the thickness of the cortex, the layer of the brain important to memory. The thickness of the cortexes of SuperAgers was equal to adults 20 to 30 years younger. Those who aged normally had a much thinner cortex.
