Study finds women's brains appear to be three years younger than men's

"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.

Goyal said that more research work is being done to confirm and better understand the implications of the research, which could even explain why women tend to stave off cognitive decline for longer.

'Brain metabolism might help us understand some of the differences we see between men and women as they age.' Researchers compared 205 men and women's actual age to the age of their brain based on its use of glucose and oxygen as fuel.

As adulthood progresses, people get less of the glucose pumped through the brain, reducing the energy funneled into the process.

The team initially hoped to use the metabolic information to predict a person's age. Sex differences during brain development, then, might set the stage for the overall trajectory of brain aging. Then they reversed the method and had the pc estimate an individual's age based mostly on mind metabolism knowledge.

Still, Goyal noted that the difference between men and women's brain ages was relatively small compared with other well-known sex differences, such as height. And Goyal says the group puzzled whether or not this distinction was extra pronounced in males or females. A machine-learned algorithm found that women's brains were on average about 3.8 years younger than their chronological ages. Female's brains appeared about four years youthful, commonly. The answer has been found through research which shows that time wears differently on women's and men's brains. "This might mean women are a little bit more resilient to certain aspects of brain aging in general, but it could also introduce certain vulnerabilities".

As adulthood progresses, less and less glucose is pumped through people's brains and by the time we're 60, only a tiny amount makes its way through our minds.

How? The steps are a lot like those meant to prevent diabetes, Brinton says.

NEW YORK, Feb 5 ― Women tend to outlive men and stay mentally sharp longer, and a new study out yesterday could explain why: female brains appear on average about three years younger. NPR's Jon Hamilton reports. The participants took part in six studies across the Washington University School of Medicine. Special scans revealed each brain's metabolism, something that decreases with age.

This study will be of interest to scientists in helping understanding of how our brains age. It's about maybe 90 percent accurate.

Even so, for some individuals, there was a giant distinction between their mind age and their chronological age.

HAMILTON: Or is it something else, like genetics?

ROBERTA DIAZ BRINTON: It's great news for many women. While the brain tends to shrink with age, men's diminish faster than women's. They're also at risk for Type 2 diabetes. To test this hypothesis in vivo, we analyzed sex differences in a unique brain PET dataset in over 200 normal human adults across the adult life span. They embody eating regimen, exercise and drugs that assist the mind and physique metabolize sugar.
