Is cognitive reserve associated with the prevention of cognitive decline after stroke? A Systematic review and meta-analysis.

[EN]Objective: To conduct a systematic review and meta-analyses of the effect of socio-behavioral cognitive reserve (CR) proxies on cognitive decline after stroke. Method: Three journal search and indexing databases (PubMed, Scopus and Web of Sciences) were crossed to examine the scientific evidence...

Method: Three journal search and indexing databases (PubMed, Scopus and Web of Sciences) were crossed to examine the scientific evidence systematically. In addition, meta-analytic techniques, using mixed-effect methods, were carried out to estimate the impact (pooled effect size) of CR proxies on either dementia inci dence or cognitive decline after stroke. Results: Twenty-two studies were included in the systematic revision, whereas nineteen of them were eligible for the meta-analysis. The findings showed that high education is associated with a decreased rate of post-stroke dementia.

Second, a main cognitive change effect was found, pointing to greater cognitive change after stroke in those with low vs. high CR. Conclusions: Our findings emphasize that CR may prevent cognitive decline after stroke, but this effect can be modulated by different factors such the CR proxy and individual characteristics such as age or type of lesion. The methodological divergences of the studies (i.e., follow-up intervals, cognitive outcomes) need unification to diminish external sources of variability for predicting rates of cognitive decline after stroke.Publicación en abierto financiada por la Universidad de Salamanca como participante en el Acuerdo Transformativo CRUE-CSIC con Elsevier, 2021-2024Elsevier202420242022info:eu-repo/semantics/articlehttp://hdl.handle.net/10366/154125reponame:GREDOS.
