We explored the effects of tDCS on cognitive performance in PSD.</p><p><strong>Methods: </strong>An exploratory analysis was conducted in 48 patients from a double-blinded, sham-controlled, randomized clinical trial that investigated the effects of tDCS for treating PSD. A neuropsychological battery was applied at baseline and endpoint. We assessed three key domains: (1) Stroop effect, measured by the Stroop test components (color naming, word-reading and word-color interference); (2) processing speed, assessed using the Trail Making Test and the Digit Symbol coding test; (3) executive function, evaluated with the Digit Span test and the Frontal Assessment Battery (FAB). A Linear mixed regression models were used to evaluate changes according to groups.</p><p><strong>Results: </strong>We found that the active tDCS group worsened slightly, while the sham group improved in Executive Function for the adjusted models. Significant interactions were also found for FAB.</p><p><strong>Conclusions: </strong>We found no consistent evidence that tDCS significantly improved the cognitive domains. The bidirectional association with cognition analysis suggest that tDCS effects may vary based on depression severity and task complexity.</p>","PeriodicalId":21244,"journal":{"name":"Revista Brasileira de Psiquiatria","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142966406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
