Vitamin D deficiency has been associated with schizophrenia and cognitive impairment, particularly in executive functions. Objective: To evaluate the relationship between vitamin D levels and performance in executive functions, processing speed, precision, and concentration in patients with schizophrenia and other organic mental disorders. Method: Retrospective, cross-sectional study with convenience sampling. The sample included 113 adults (66 with schizophrenia and 47 with other mental conditions) admitted to the Institute of Neurosciences of Guayaquil, aged between 22 and 85 years. Results: The findings indicate a significant correlation between vitamin D levels and performance in executive functions. Higher levels of vitamin D were associated with less deterioration of executive functions in patients with schizophrenia and organic damage. Processing speed was higher in patients with optimal vitamin D levels compared to those with deficiency. In patients with organic damage, low levels of vitamin D were associated with lower precision and concentration. Conclusions: This study suggests that adequate levels of vitamin D can improve executive functions in people with schizophrenia and other organic mental disorders. Vitamin D supplementation is recommended in treatments to improve clinical outcomes and the quality of life of these patients. Early detection and intervention are crucial to prevent further cognitive decline.\u00a0<\/jats:p>","DOI":"10.21500\/20112084.7279","type":"journal-article","created":{"date-parts":[[2025,7,26]],"date-time":"2025-07-26T15:46:29Z","timestamp":1753544789000},"page":"106-114","source":"Crossref","is-referenced-by-count":0,"title":["Vitamin D levels and executive functions in subjects with chronic mental disorders"],"prefix":"10.21500","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1696-6892","authenticated-orcid":false,"given":"Jos\u00e9 Alejandro","family":"Valdevila Figueira","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4402-9019","authenticated-orcid":false,"given":"Bryan","family":"Jauregui Ruiz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4691-6626","authenticated-orcid":false,"given":"Sergio Esteban","family":"Castillo Jaramillo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-9800-4280","authenticated-orcid":false,"given":"Indira Dayana","family":"Carvajal Parra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2311-5217","authenticated-orcid":false,"given":"Roc\u00edo","family":"Valdevila Santiesteban","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-6612-4231","authenticated-orcid":false,"given":"Luis Patricio","family":"Benenaula Vargas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"8948","published-online":{"date-parts":[[2025,7,25]]},"container-title":["International Journal of Psychological Research"],"original-title":[],"link":[{"URL":"https:\/\/usb-prueba.metadatos.org\/index.php\/IJPR\/article\/download\/7279\/5678","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/usb-prueba.metadatos.org\/index.php\/IJPR\/article\/download\/7279\/5678","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,7,26]],"date-time":"2025-07-26T15:46:30Z","timestamp":1753544790000},"score":1,"resource":{"primary":{"URL":"https:\/\/usb-prueba.metadatos.org\/index.php\/IJPR\/article\/view\/7279"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,7,25]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2025,5,22]]}},"URL":"https:\/\/doi.org\/10.21500\/20112084.7279","relation":{},"ISSN":["2011-7922","2011-2084"],"issn-type":[{"type":"electronic","value":"2011-7922"},{"type":"print","value":"2011-2084"}],"subject":[],"published":{"date-parts":[[2025,7,25]]}}}
