46/100

✓ Peer-reviewed alzhub usefulness score 46 out of 100. Prevention trials

Topic: Risk, prevention and care in population studies

There were no significant associations in men. By contrast, women with a dietary score of 8-10 points (B = 0.05, 95% CI: -0.002; 0.097), and those with a score of 11-17 points (B = 0.08, 95% CI: 0.016; 0.140) had a higher composite cognitive score than women in lowest adherence group. Regarding specific domains, women in the highest adherence group had significantly better immediate verbal memory (B = 0.12, 95% CI: 0.031; 0.205) and delayed recall (B = 0.12, 95% CI: 0.027; 0.212), respectively, than those in the lowest adherence group. Higher adherence to the MDS was associated with better cognitive functioning in verbal memory and composite cognitive score in Czech women. The results suggest that the Mediterranean diet may help to improve cognitive functioning.

Key findings

There were no significant associations in men.

Higher adherence to the MDS was associated with better cognitive functioning in verbal memory and composite cognitive score in Czech women.
The results suggest that the Mediterranean diet may help to improve cognitive functioning.

Why it matters

In this cross-sectional study of Czech adults, women with higher Mediterranean diet scores had better verbal memory and overall cognitive scores, while no significant associations were found in men. The results suggest the Mediterranean diet may help improve cognitive functioning in women.
