In the brain examinations of 84 men and 121 women aged 20 to 82, the researchers pointed out that women's brains were about three years younger than men's brains.
A recent study, published in the PNAS (Proceedings of the National Academy of Sciences), showed that the female brain is on average about three years younger than men of the same chronological age.
Researchers at the Washington University School of Medicine in the state of Missouri (USA) badyzed the metabolism of the human brain, particularly how it treats glucose, which changes depending on the age of the person.
As the person grows up, the brain burns fewer and fewer calories as part of a process called aerobic glycolysis, which tracks the growth and development of the brain. According to these data, the researchers decided to compare the brain examinations of 84 men and 121 women aged 20 to 82 to check how their brains treated glucose.
Thus, scientists revealed that unlike the brain age of volunteers, it was about three years on average, so that the brains of women were up to three years older than young, biologically, than men. same chronological age.
According to the experts, it remains to be determined whether this finding may explain the fact that older women are less likely to lose their memory, resulting in lower mental performance than men of the same age.
