As Biden’s memory issues draw attention, neurologists weigh in

What are normal memory changes?

It’s normal for older brains to have more difficulty retaining new information and then retrieving the information, but mental processes like decision-making and judgment can actually improve with age, said Dr. Thomas Wisniewski, director of NYU Langone Health’s Alzheimer’s Disease Research Center and its Center for Cognitive Neurology.

“Although the raw power of memory has some degree of decline, perhaps wisdom can increase because the individual has a greater backlog of experiences and different situations as to what is the best thing to do,” Wisniewski said.

While the conversation surrounding aging is often framed around a person’s diminishing memory or executive functioning, there are cognitive benefits that come with growing older, Selkoe said.

“There is a type of emotional intelligence and ability to handle many different kinds of experiences in life that come with greater longevity,” he said. “People can make decisions more carefully and more rationally.”
