Methods: A total of 264 participants were divided into three groups based on cognitive status: cognitively healthy, subjective cognitive, and mild cognitive impairment. All participants were assessed using the Sniffin\u2019 Sticks Olfactory Identification test and a comprehensive neuropsychological test battery. Results: Our results highlight the main effects of age and cognitive status on OI scores. Regarding cognitive abilities, OI is associated with measures of short-term memory, long-term, working memory, and selective attention. Finally, logistic regression models showed that OI is a significant predictor for discriminating SCD from CH, MCI from CH, and MCI from SCD. Discussion: These findings suggest the addition of olfactory identification measures in neuropsychological assessments could improve the early detection of individuals at risk for cognitive impairment.<\/jats:p>","DOI":"10.3390\/ejihpe14120196","type":"journal-article","created":{"date-parts":[[2024,12,5]],"date-time":"2024-12-05T09:30:18Z","timestamp":1733391018000},"page":"2978-3000","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Olfactory Identification as a Biomarker for Cognitive Impairment: Insights from Healthy Aging, Subjective Cognitive Decline, and Mild Cognitive Impairment"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1267-5377","authenticated-orcid":false,"given":"Jaime","family":"Bouhaben","sequence":"first","affiliation":[{"name":"Experimental Psychology, Cognitive Processes and Speech Therapy Department, Faculty of Psychology, Complutense University of Madrid, 28223 Pozuelo de Alarc\u00f3n, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alice Helena","family":"Delgado-Lima","sequence":"additional","affiliation":[{"name":"Experimental Psychology, Cognitive Processes and Speech Therapy Department, Faculty of Psychology, Complutense University of Madrid, 28223 Pozuelo de Alarc\u00f3n, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8808-4613","authenticated-orcid":false,"given":"Mar\u00eda Luisa","family":"Delgado-Losada","sequence":"additional","affiliation":[{"name":"Experimental Psychology, Cognitive Processes and Speech Therapy Department, Faculty of Psychology, Complutense University of Madrid, 28223 Pozuelo de Alarc\u00f3n, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"105","DOI":"10.1177\/1533317515592331","article-title":"From Subjective Cognitive Complaints to Dementia: Who Is at Risk?: A Systematic Review","volume":"31","author":"Alves","year":"2016","journal-title":"Am.
