Conventional swallowing rehabilitation often yields limited functional recovery.

The joint analysis highlighted that coupling regular PA with sleep exceeding 9 h was associated with a 42% decrease in dementia risk, whereas pairing it with 9 h or less of sleep yielded a 60% decrease in mortality risk.</div></div><div><h3>Conclusion</h3><div>For elderly stroke survivors, PA confers protective effects against both dementia and all-cause mortality. This association is partially mediated by the reduced risk of dementia. Furthermore, the beneficial impact of regular PA on these outcomes is moderated by sleep duration, underscoring the necessity of a joint consideration of both factors in prognostic assessments.</div></div>","PeriodicalId":54368,"journal":{"name":"Journal of Stroke & Cerebrovascular Diseases","volume":"35 3","pages":"Article 108547"},"PeriodicalIF":1.8,"publicationDate":"2026-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146021124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
