Women usually live longer than men and also maintain mental focus longer. Study published in Annals of the National Academy of Sciences, but I could explain why. The research is summarized by the Slovenian press agency.
The study involved 121 women and 84 men who were diagnosed with metabolism in the brain, providing oxygen and glucose to the brain. For the brain, as with other organs in the body, the fuel is glucose. But how the brain interacts can tell a lot about your age.
Study participants were between 20 and 80 years of age, and in all age brackets, women's brains appeared, according to the metabolism younger than men, the results of researchers with Washington Medical School in St. Petersburg Louis.
The algorithm showed that women's brains were on average about 3.8 years younger than the actual chronological age of women. The brains of men were, on average, 2.4 years older than the real age of men.
Male adulthood comes after
"This does not mean that the male brain ages faster" commented one of the main authors of the study Manu Goyal, assistant professor of radiology at the university. As he explained, male adulthood starts about three years longer than women, and therefore, the end of life remains.
The question of why this does not have a clear answer for now. Scientists hope they are able to determine if differences in metabolism in the brain can play a protective role for women who are generally better than men on mental skills exams such as remembering or resolving problems in older years.
According to Goyala, this could mean that the reason why women in the elderly do not experience such crazy cognitive abilities as the same old man is that their brains are actually younger, STA writes.
