A recent study of brain metabolism shows that women’s brains turn out to be four years younger than men’s brains, particularly when it comes to energy consumption. The U.S. scientists discovered that women’s brains have a younger metabolic age than men’s, which manifests itself vividly since the late teenage years and into the old age. Women’s brains tend to use the energy moderately during their lifetime, which might be one of the reasons women are statistically more mentally agile in the old age than men.
The U.S. scientists performed brain scanning to determine how sugar transforms into energy in brains of people of varying age. They then used the collected data to map out the differences between sexes and got an unexpected result: women’s brains turned out to be 3.8 years younger on average. Researchers say the real question is why this is happening and what it is supposed to mean.
In the meantime, the findings of the study could be helpful for investigating neurodegenerative diseases in old people, as well as learning difficulties and memory loss.
