It also points out that brain metabolism slows down with age. “For each person, we determined the fraction of sugar committed to aerobic glycolysis in various regions of the brain,” Goyal said. “We trained a machine-learning algorithm to find a relationship between age and brain metabolism by feeding it the men’s ages and brain metabolism data.”The researchers found that the algorithm yielded women’s brain ages that are younger with an average of 3.8 years than the women’s actual ages. The relative youthfulness of women’s brains was detectable even among the youngest participants, who were in their twenties. Younger men did not score that well.
