A new study found that women's brains looked three or four years younger than those of men of the same age.

In one study published in the Proceedings of the National Academy of Science, scientists at the University of Washington in St. Louis suggested that higher rates of juvenile glycolysis – the breakdown of glucose by enzymes – helped to promote learning and women's brain development, even in old age.

"We are just beginning to understand how various gender-related factors could affect the trajectory of brain aging and how this could affect the brain's vulnerability to neurodegenerative diseases," said lead researcher Manu Goyal at the Independent. "The brain metabolism could help us understand some of the differences we see between men and women as they age."

The people tested in the study ranged from 20 to 82 years old – and the relative youthfulness of women's brains was also visible among young people.

"It's not that men's brains are aging faster: they start in adulthood with about three years older than women, and this persists for life," Goyal told the newspaper.

Brain aging is associated with a gradual decrease in cerebral metabolism.

In their new study, scientists have tried to measure the "metabolic age" of people's brains, focusing on a process that uses glucose-glucose to support brain development as children grow up, passing of adulthood.

As adulthood progresses, less glucose pumped into the brain is absorbed, reducing the energy channeled into the process. Only a small amount between when people are in their sixties.

According to The Independent, women's brains are known to be more resilient to cognitive decline, with older women tending to perform better than men of the same age on reason, memory and problem-solving skills.
