Machine learning (ML) methods enable the integration of miRNAs into highly accurate predictive models of dementia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To investigate the differential expression of miRNAs across dementia subtypes compared to normal controls (NC) and analyze their enriched biological and disease pathways.

Incorporating these miRNAs into ML classifiers resulted in up to a 27% improvement in dementia risk prediction. Pathway analysis highlighted neuronal and eye disease pathways associated with dementia risk. Sex-specific analyses revealed unique biomarkers for males and females, with miR-128-1-5 as a protective factor for males in AD, VaD, and DLB, and miR-4488 as a risk factor for female AD, highlighting distinct pathways and potential therapeutic targets for each sex.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our findings support existing dementia etiology research and introduce new potential and sex-specific miRNA biomarkers.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/25424823251317177","type":"journal-article","created":{"date-parts":[[2025,2,14]],"date-time":"2025-02-14T01:07:26Z","timestamp":1739495246000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Machine learning uncovers novel  sex-specific dementia biomarkers  linked to autism and eye diseases"],"prefix":"10.1177","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-7964-9441","authenticated-orcid":false,"given":"Ayub","family":"Khan","sequence":"first","affiliation":[{"name":"Department of Computer Science, Colgate University, Hamilton, NY, USA"},{"name":"Department of Biology, Colgate University, Hamilton, NY, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-0928-8935","authenticated-orcid":false,"given":"Ali R","family":"Ghasemi","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Colgate University, Hamilton, NY, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4512-1549","authenticated-orcid":false,"given":"Krista K","family":"Ingram","sequence":"additional","affiliation":[{"name":"Department of Biology, Colgate University, Hamilton, NY, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0726-5461","authenticated-orcid":false,"given":"Ahmet","family":"Ay","sequence":"additional","affiliation":[{"name":"Department of Biology, Colgate University, Hamilton, NY, USA"},{"name":"Department of Mathematics, Colgate University, Hamilton, NY, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,2,13]]},"reference":[{"key":"bibr1-25424823251317177","unstructured":"World Health Organization.
