After restricting publications to 2000 onward and excluding non\u2010analytic document types, 3,479 records were included in the bibliometric analysis. A subset of 3,223 original articles was used for thematic analyses. Publication trends, authorship, institutional collaboration, keywords, biomarker themes, ML objectives, data modalities, methods, shared research resources, and large language model (LLM) applications were evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>ML\u2010related dementia research increased substantially over time. Diagnostic classification was the predominant ML objective (55.0%), followed by early detection or screening (10.3%), progression or cognitive\u2010decline prediction (6.8%), and biomarker or feature discovery (4.7%). Structural magnetic resonance imaging was the most frequently identified modality (42.6%), followed by clinical or cognitive data (22.4%), positron emission tomography\/single photon emission computerized tomography (10.3%), and genetic or genomic data (10.2%). Prominent biological themes included hippocampal measures, amyloid\/A\u03b2, electroencephalogram, tau\/p\u2010tau, and cerebrospinal fluid biomarkers. Institutional networks showed distinct international collaboration clusters and frequent use of shared infrastructures.
