We comprehensively characterized gut microbiota and metabolomic profiles in fecal samples from 35 individuals, including 16 spousal pairs in which one partner had MCI. Compared with controls, MCI cases exhibited significantly elevated levels of\n                    <jats:italic>Izemoplasmatales<\/jats:italic>\n                    spp. in the fecal microbiome and proline in the metabolome, along with decreased levels of\n                    <jats:italic>Ruminococcus<\/jats:italic>\n                    spp.,\n                    <jats:italic>Lachnospira<\/jats:italic>\n                    spp., and fumaric acid. Among MCI cases, rapid progressors showed significantly increased\n                    <jats:italic>Bilophila<\/jats:italic>\n                    spp. in the microbiome, accompanied by higher arginine, aspartic acid, and hypoxanthine in the metabolome, and reduced\n                    <jats:italic>Coprococcus<\/jats:italic>\n                    spp., compared with slow progressors. Machine learning models integrating microbiota and metabolite features identified marker sets that accurately distinguished MCI cases from matched cognitively healthy controls (AUC: 0.944) and predicted rapid disease progression, with the integrated model outperforming single\u2010modality models for diagnosis. These findings identify distinct gut microbiota and metabolite signatures associated with MCI, highlighting their potential as candidate biomarkers for early diagnosis and risk stratification, thereby addressing the unmet need for simple tests for early detection.\n                  <\/jats:p>","DOI":"10.1002\/mco2.71045","type":"journal-article","created":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T07:50:04Z","timestamp":1791273004000},"source":"Crossref","is-referenced-by-count":0,"title":["Profiling Gut Microbiome and Metabolites Aids Diagnosis and Prediction of Progression in Mild Cognitive Impairment"],"prefix":"10.1002","volume":"7","author":[{"given":"Birong","family":"Zhang","sequence":"first","affiliation":[{"name":"Division of Infection and Immunity School of Medicine Cardiff University  Cardiff Wales UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"Brown","sequence":"additional","affiliation":[{"name":"Division of Infection and Immunity School of Medicine Cardiff University  Cardiff Wales UK"},{"name":"UK Dementia Research Institute Cardiff School of Medicine Cardiff University  Cardiff Wales UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antony","family":"Bayer","sequence":"additional","affiliation":[{"name":"UK Dementia Research Institute Cardiff School of Medicine Cardiff University  Cardiff Wales UK"},{"name":"Memory Team Cardiff and Vale University Health Board Routledge Academic Centre University Hospital Llandough  Penarth UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanna","family":"Waring","sequence":"additional","affiliation":[{"name":"Memory Team Cardiff and Vale University Health Board Routledge Academic Centre University Hospital Llandough  Penarth UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.
