ObjectivesTo investigate the association between social and psychological factors and the risk of cognitive impairment following acute ischemic stroke.Materials and methodsA prospective study was conducted at Shanghai Tenth People’s Hospital from June 2021 to July 2022. The study focused on social and psychological factors, which were assessed using the Social Support Rating Scale (SSRS), Self-Perceived Burden Scale (SPBS), and Hamilton Depression Scale (HAMD) within 3 days after admission to the hospital. Cognitive function was evaluated using the Montreal Cognitive Assessment at 3 months post-stroke. Logistic hierarchical regression models were used to examine the association between these three indicators and cognitive impairment following a stroke.ResultsAmong these patients, cognitive function was assessed in 211 cases at the 3-month follow-up after the initial stroke event. At 3 months post-stroke, 118(55.9%) of the participants experienced cognitive impairment, while 93(44.1%) did not. The scores on the SPBS and HAMD showed significant associations with cognitive impairment at 3 months after stroke. The scores of SPBS [scores: 30~39 vs.7 vs.≤7 points, OR=3.287(1.362~7.936); P=0.008]. There were no significant associations observed between SSRS and PSCI.ConclusionEarly screening for depressive symptoms and focusing on self-perceived burden can be beneficial for decision support for clinicians and improve cognitive function recovery at the 3-month mark post-stroke.

Background Expert Consensus on the Management of Cognitive Impairment after Stroke 2021 has made it clear that, post-stroke cognitive impairment (PSCI) prevalence needs to be assessed by cognitive assessment 3-6 months after stroke, but the influencing factors found by existing studies are still controversial and need the support of EBM evidence. Objective To investigate the influencing factors of cognitive impairment 3 to 6 months after ischemic stroke, to provide an evidence-based reference for the prevention and intervention of PSCI. Methods We searched databases of the Cochrane Library, PubMed, EMBase, CINAHL, Web of Science, CNKI, SinoMed, VIP and Wanfang Data for cohort studies or case-control studies about influencing factors of cognitive impairment 3 to 6 months after ischemic stroke from inception to December 2020. RevMan5.3 software was used to conduct the Meta-analysis. Results A total of 27 studies were finally included, involving 8 677 patients (4 322 with PSCI and the other 4 355 without) . Meta-analysis results demonstrated that, age〔OR=1.10, 95%CI (1.06, 1.14) , P
