NEW YORK (Reuters Health) – Women live longer than men and their mental health is better, because their brains are three years younger than men’s brains, a new study shows.
Participants in the study, which included 84 men and 121 women, took a CT scan to measure the speed of switching brain substances, or the flow of oxygen and sugar into the brain.
Like other members of the body, the brain uses sugar as a substance to run it. The way in which sugar is consumed shows a lot about the age of the brain.
The participants’ ages ranged from the 1920s to the 1980s, and women’s brains were younger than men’s brains in terms of flow and consumption, according to research published in the National Academy of Sciences.
The brains of women were 3.8 years younger than their real age. Compared with men, their brains were 2.4 times higher than their real age.
“This does not mean that the brains of men are faster than the brains of women, but they reach the age of three years before women, which lasts their whole lives,” said Mano Goyal, an assistant professor at the University of Washington School of Medicine.
Researchers hope to see whether brain differences play a role in preventing women who wish to register better results in cognitive tests, memory and problem solving at an advanced age.
