Biological age of women's brains 3 year younger than men's
One aspect of brain metabolism, aerobic glycolysis, is a biomarker of brain ageing.
The fraction of sugar powering glycolysis in the brain declines with age.
200 people scanned to measure oxygen and glucose flow through their brains.
Women's brains found to be three to four years more youthful than male's.
Men’s brains not ageing faster – they start adulthood metabolically older than women's.
Women are less susceptible to memory loss and neurological diseases as they age.
