Association of cognitive reserve with stroke outcome: A systematic review and meta-analysis

We found evidence that CR explains inter-individual variability in stroke outcome and thus may improve its prediction. Low CR increases the risk of poor stroke outcome, and its proxies should be considered in both clinical and research settings. However, we observed high heterogeneity across studies, and further research with specific focus on this topic and CR-proxies extending beyond educational and occupational attainment is needed.
