✓ Peer-reviewed alzhub usefulness score 54 out of 100. How common it is

Topic: Amyloid, tau and blood-test diagnosis

The study cohort comprised a total of 6108 individuals diagnosed with AD dementia during the study period (28.4% males and 71.6% females). MMSE scores exhibited an average decline of approximately two units per year, unaffected by sex. Similarly, the decline in most neuropsychological functions assessed by NBACE did not exhibit significant differences between males and females. However, we observed that women diagnosed with mild AD dementia progressed more rapidly based on their CDR score (HR = 2.57, 95%CI:2.33-2.84) than men (HR = 2.03, 95%CI: 1.71-2.41) (p-interaction = 0.01). Our findings do not strongly support the notion that sex significantly modifies the clinical progression of AD dementia based on cognitive data. Further research is essential to validate whether women with mild AD dementia indeed progress more rapidly than men at a similar stage and to delve into the potential underlying reasons for this finding.

Key findings

Why it matters

In a large memory unit cohort, cognitive decline was largely similar between men and women with Alzheimer's dementia, though women with mild dementia progressed faster on one measure. The authors say their findings do not strongly support sex significantly modifying clinical progression and call for further research.
