There's a Good Reason Why Aging Brains Might Forget Smaller Details
As we get older, our brains prioritise wisdom over remembering little details for good reason, according to new research. Whether you are young or old, this is worth a read.
This refreshingly positive study postulates that forgetting the little things (like where you put your car keys) could be your brain’s way of adapting to prioritise bigger-picture thinking, rather than a sign of decline. So, if you reckon you have become slightly more forgetful as you get older, this new research is rather comforting - and definitely worth remembering. In a nutshell, University of Arizona researchers argue that the aging brain does not cognitively decline but rather shifts its priorities.
“What the goals of an older brain are are quite different than the goals of a younger brain,” co-author Fabian-Xosé Fernandez explained to The Washington Post. The study analyzed research suggesting that older adults’ brains rely less on the hippocampus, the part of the brain responsible for forming new memories, spatial navigation, and learning details. Instead, they rely more on the prefrontal cortex, which is associated with higher-level thinking and emotional regulation.
Previously, scientists have theorized that older adults compensate for hippocampal decline by relying on the cortex. However, Fernandez and his fellow authors argue this shift could serve an evolutionary purpose to help older adults share knowledge with younger generations. “It’s this ability to melt away that which does not matter and get to the essence of an issue,” he explained.
Fernandez believes the strengths of the aging brain should be embraced and nurtured by society with intergenerational social connection. “People see older individuals and look at them as not being on par with younger individuals across a lot of metrics,” Fernandez told the Association for Psychological Science. “The way I look at it is that you’ve got someone with a brain that has been active for several decades and has seen a lot. There is tremendous value there, and we don’t do a good job of unlocking it.”
