Brain Drain? Women's Brains Appear Younger Than Men's, Study Finds | Fox&Co. Mental Health
See Author Article Here By Doyle Rice Talk about a brain drain. A new study suggests men's brains appear to be older than women's brains. In terms of brain metabolism, the brain of a typical 30-year-old woman appears to be three to four years younger than the brain of a 30-year-old man, the study says. This remains true throughout the adult life span and may be one clue as to why women often stay mentally sharp longer than men. "Brain metabolism might help us understand some of the differences we see between men and women as they age," said study lead author Manu Goyal, an assistant professor of radiology at the Washington University School of Medicine in St. Louis. The study participants – 121 women and 84 men, ranging in age from 20 to 82 years – underwent PET scans to measure the flow of oxygen and glucose in their brains. Men's brains appear older than women's brains, according to a new study published in the Proceedings of the National Academy of Sciences.
