Women May Have More Youthful Brains Than Men

Men's brains are almost four years "older" than those of females the same age, explaining why women stay sharper for longer in old age, according to new research. As a result, we can count on the fact that our brains would likely function differently.

In the study published in the journal Proceedings of the National Academy of Sciences, researchers studied 205 people to figure out how their brains use sugar. They found that, when trained on men's data, the algorithm yielded brain-metabolic ages for the women that were 3.8 years younger than the women's chronological age.

The PET data showed how glucose and oxygen were used in different regions of the brain and the overall blood flow. "I think this could mean that the reason women don't experience as much cognitive decline in later years is because their brains are effectively younger, and we're now working on a study to confirm that", Goyal said The study shows that older women tend to score better than men of the same age on tests of reason, memory and problem solving. The relative sprightliness was detectable even among the youngest subjects, who were in their twenties.

Goyal said that while the differences between the brain age of men and women was "significant", it was "nowhere near as big a difference as some sex differences, such as height". The researchers created algorithms to calculate the metabolic ages of the participants, which they compared to their chronological ages, reported Eyewitness News. They had started out by trying to predict a person's age from the metabolic processes of his or her brain.

That may help protect against the loss of grey matter which causes thinking problems in old age, although more research is needed to discover if this is the case. We find that in terms of brain metabolism, the adult female brain is on average a few years younger than the male brain.

The study involved PET scans from 165 adults aged between 20 and 80.

Goyal and his colleagues believe that the greater youthfulness in the female brain might give a degree of resilience to aging-related changes. However the rates tend to be faster among men than women, they found.

A group of researchers from the USA took specialist brain scans from almost 200 healthy adults aged between 20 and 80.

The researchers suspect that women gain this advantage during puberty, Goyal said. We can't be sure that the same findings would be seen in other population groups, including for example people with degenerative brain diseases like Alzheimer's. Having a younger brain for longer could make the brain more vulnerable to certain things as well.

"I think this could mean that the reason women don't experience as much cognitive decline in later years is because their brains are effectively younger, and we're now working on a study to confirm that", he added. So they had a computer study how metabolism changed in both men and women.

Accordingly, it is important to understand the factors that influence brain aging, particularly in the context of an aging population. Female's brains appeared about four years youthful, commonly.

The U.S. National Institute on Aging has more about the aging brain.
