    Area of Science:

    • Neurology
    • Biomedical Engineering
    • Computational Biology

    Background:

    • Accurate in vivo prediction of neuropathology is crucial for diagnosing and treating Alzheimer's disease and related dementias (ADRDs).
    • Individuals with ADRDs often present with mixed pathologies, necessitating comprehensive diagnostic approaches.
    • Inferring neuropathologic changes from clinical data, biofluid assays, and neuroimaging is an area of active research.

    Purpose of the Study:

    • To evaluate automated machine learning models for predicting 26 autopsy-confirmed neuropathological outcomes in vivo.
    • To assess the predictive performance of clinical data, cerebrospinal fluid (CSF) biomarkers, and various neuroimaging modalities.
    • To quantify the added value of neuroimaging and CSF biomarkers compared to clinical features alone.

    Main Methods:

    • Utilized automated machine learning models trained on data from 7,894 individuals curated by the AD Sequencing Project Phenotype Harmonization Consortium.
    • Employed ensemble learning with stratified cross-validation to train predictive models.
    • Assessed model performance using Spearman's rank correlation and Matthews correlation coefficient, considering co-occurring pathologies.

    Main Results:

    • Braak stage was among the most consistently predicted neuropathological outcomes.
    • CSF biomarkers effectively predicted beta-amyloid and tau pathology.
    • Diffusion MRI metrics showed superiority in predicting vascular brain injury, white matter injury, and Lewy body disease.
    • Structural MRI measures outperformed clinical assessments for neurodegeneration and hippocampal sclerosis.
    • White matter hyperintensities (WMH) complemented cognitive measures in predicting TDP-43 pathology.

    Conclusions:

    • Machine learning models can effectively infer various neuropathologies from multimodal in vivo data.
    • Different data modalities (CSF, diffusion MRI, structural MRI, clinical data) offer complementary strengths in predicting specific pathologies.
    • These findings establish a valuable baseline for comparing different data modalities in neuropathology inference.
