This association was consistent across all examined moderators, including various neurocognitive outcomes, age, gender, study design, study population, study quality, type of PTSD measure, and comorbidities such as depression, substance use, and TBI.<b>Conclusions:</b> These findings collectively suggest that PTSD is associated with both cognitive impairment and NCD. This emphasizes the need for early intervention (including prevention strategies) of PTSD, alongside monitoring cognitive function in affected individuals.International Prospective Register of Systematic Reviews (PROSPERO) registration number: CRD42021219189, date of registration: 02.01.2021.</p>","PeriodicalId":12055,"journal":{"name":"European Journal of Psychotraumatology","volume":"16 1","pages":"2469978"},"PeriodicalIF":4.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11894747/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143585209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
