Men’s Health Month: Women’s brains appear younger than men’s, study finds


What’s in a number when it comes to age?

Adult female brains appear, on average, a few years younger than same-aged male brains, a new study finds. This suggests that sex affects how our brains age, which in turn might influence our tendency to develop neurodegenerative diseases such as Alzheimer’s, according to research published Monday in the journal Proceedings of the National Academy of Sciences of the United States.

“We don’t see brain aging itself as something that needs to be ‘halted’,” Dr. Manu S. Goyal, lead author of the study and an assistant professor of radiology and neurology at Washington University in St. Louis, wrote in an email.

It’s the diseases that come with brain aging that are the problem, he said: “So what we need to understand is how brain aging contributes to diseases such as Alzheimer’s disease, and why some people are more or less resilient to developing Alzheimer’s and other brain diseases.”
