Machine Learning in Dementia Research: Trends, Biomarkers, Prediction Goals, and Data Modalities.
Article in Brain and behavior, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveMachine learning (ML) is increasingly used in dementia research for diagnosis, early detection, prognosis, biomarker characterization, and disease phenotyping. This study aimed to provide a bibliometric and thematic overview of ML applications in dementia, emphasizing biological mechanisms, prediction goals, data modalities, collaborative networks, and emerging computational approaches.
methodsA title-field search of the Web of Science Core Collection identified 3,833 records related to ML and dementia. After restricting publications to 2000 onward and excluding non-analytic 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.
resultsML-related 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-decline 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/Aβ, electroencephalogram, tau/p-tau, and cerebrospinal fluid biomarkers. Institutional networks showed distinct international collaboration clusters and frequent use of shared infrastructures. Transformer-based and LLM approaches emerged in recent years.
conclusionsML research in dementia has expanded beyond diagnostic neuroimaging toward multimodal, biomarker, prognostic, and language model applications, although diagnostic classification and structural imaging remain dominant. Emphasis on biological integration, longitudinal validation, and clinical translation are needed.
