Oslo, Oct 19: New research suggests that male brains may experience faster age-related shrinkage than female brains, offering fresh insights into the biology of brain aging. The study analysed more than 12,000 brain scans from 4,726 participants aged 17 to 95, each having at least two MRIs over an average interval of three years.
The researchers found “modest yet systematic sex differences” in how neurological tissue declines. Men showed volume loss in a greater number of brain regions, including various parts of the cortex, while women experienced decline in fewer regions and maintained greater cortical thickness with age.
Despite women being diagnosed with Alzheimer’s at twice the rate of men, the study revealed that female brains may actually lose gra
