Association between the dietary index for gut microbiota and post-stroke depression: a cross-sectional study

This study identified a negative association between DI-GM scores and the prevalence of PSD. Our findings suggest that dietary patterns beneficial to gut microbiota are associated with lower rates of PSD, and that this relationship is inter-related with BMI. These results highlight the potential clinical relevance of integrated dietary and weight management strategies, though longitudinal studies are needed to confirm any causal pathways.
