Story summary

New research analyzing 12,000 brain scans across ages 17 to 95 finds that men may experience faster brain shrinkage with age.
Men showed declines in more brain regions than women, while women had less cortical thinning and slower loss of gray and white matter.
The study notes a significant sex bias in neuroscience research, with only 5% of studies considering sex differences, and calls for further investigation.
