A new study published recently by the Washington University School of Medicine showed that women’s brains are four years younger than men’s brains and outscore them in sharp memory tests, especially with aging. Participants in the study, 84 men and 121 women (aged between 20 and 82 years), underwent PET scans to measure brain metabolism or the flow of oxygen and glucose in their brains. As a result, female brains appeared younger than their male peers. The study also indicated that, while women’s brains were nearly 3.8 years younger than their chronological ages, men’s brains were 2.4 years older than their true ages. The assistant professor at Washington University School of Medicine, Manu Goyal, explained that this does not mean that men’s brains age faster, but that they start adulthood 3 years older than women, and continue throughout their life.
