A Georgia State University team published findings that common cognitive screening tools used for Alzheimer’s, including the 30-point Mini-Mental State Examination (MMSE), may not reflect the same brain changes in women and men. The researchers focused on the MCI stage and found that a good MMSE score in MCI may still miss underlying brain changes in some women.
The group analyzed brain scans from 332 people at different disease stages and compared structural changes by sex and stage. They found that men tended to show more brain shrinkage earlier, when cognition moved from normal to MCI, while women showed a steeper and more widespread decline later, from MCI to Alzheimer’s. Women’s test scores were linked to a broader set of brain regions, suggesting the female brain may recruit extra areas to support function and mask some decline.
The authors argue for sex-calibrated interpretation of screening tools. Next steps include following patients over time and studying how hormones and genetics influence these differences. Current prevention advice remains the same: stay active and manage vascular health, and discuss family history with a doctor.
