A study that analyzed the brain of women and men It could be the key to determining why the female sex has a life expectancy that is far greater than that of men, but it will also have a beneficial effect on their cognitive abilities.
According to the study, 121 women and 84 men who underwent a tomography involved measuring their brain's metabolism The female sex has an aging far slower than the male with an average life span that extends over four years over men.
The stream of oxygen and glucose that the brain uses as fuel becomes more effectively played by women As well as extending them over time would also be the key according to their cognitive abilities.
The people who went through these exams were between 20 and 80 years of age and when they compared men with women, the latter seemed much better preserved, according to the US magazine Actas of the National Academy of Sciences.
"It's not that men's brains get older," explained Manu Goyal, an assistant professor of radiology at the University of Washington School of Medicine in St. Louis and added: "They start adulthood about three years older than women, and it lasts all their lives."
The algorithm describes that female brains have 3.8 years more than their chronological age, which compared to men was approx. 2.4 years older than their current age.
The main theory of this behavior is indicated in the hormones that form each metabolism at an early age. In the case of the female sex, they set a younger pattern throughout their lives.
Now the research is aimed at discovering whether these metabolic differences in the brain work in a protective way for the brain.women who tend to have better grades than men in the cognitive tests of reason, memory and problem solving in old age.
