A study that looked at the brains of women and men it could be critical to determine why females have a much longer life expectancy than males, but that would have a favorable impact on their cognitive abilities.
According to the survey, which involved 121 women and 84 men who underwent a CT scan that measured brain metabolism, Females have a much slower aging than men with an average lifetime of four years above men.
The flow of oxygen and glucose that the brain consumes as fuel is assimilated much more efficiently by women, which in addition to extending them over time would also be fundamental according to their cognitive abilities.
The people who performed these tests were between 20 and 80 years old and compared men to women, the latter seemed much better preserved, according to the American magazine Actas, of the National Academy of Sciences.
"It is not that men's brains age faster," said Manu Goyal, assistant professor of radiology at the University of Washington School of Medicine in St. Louis, adding, "They begin adulthood about three years older than women, and this persists throughout life."
The algorithm details that female brains have more 3.8 years of youth than their chronological ages, which, compared to men, were about 2.4 years older than their actual ages.
The main theory about this behavior is indicated in the hormones that shape the metabolism of each at an early age. In the case of females, they set a younger pattern throughout life.
Now, the research aims to find out if these metabolic differences in the brain work in a protective way for the brain.women, who tend to have better grades than men in cognitive tests of reason, memory, and problem solving in old age.
