Despite this growing burden, there are currently no cures, and treatment options remain limited due to disease heterogeneity, prolonged preclinical and prodromal phases, poor understanding of disease mechanisms, and diagnostic challenges. Identifying novel biomarkers is crucial for improving early detection, prognosis, staging and subtyping of these conditions. High-dimensional molecular studies in biofluids ('omics') offer promise for scalable biomarker discovery, but challenges in assembling large, diverse datasets hinder progress. To address this, the Global Neurodegeneration Proteomics Consortium (GNPC)-a public-private partnership-established one of the world's largest harmonized proteomic datasets. It includes approximately 250 million unique protein measurements from multiple platforms from more than 35,000 biofluid samples (plasma, serum and cerebrospinal fluid) contributed by 23 partners, alongside associated clinical data spanning Alzheimer's disease (AD), Parkinson's disease (PD), frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS). This dataset is accessible to GNPC members via the Alzheimer's Disease Data Initiative's AD Workbench, a secure cloud-based environment, and will be available to the wider research community on 15 July 2025. Here we present summary analyses of the plasma proteome revealing disease-specific differential protein abundance and transdiagnostic proteomic signatures of clinical severity. Furthermore, we describe a robust plasma proteomic signature of APOE \u03b54 carriership, reproducible across AD, PD, FTD and ALS, as well as distinct patterns of organ aging across these conditions. This work demonstrates the power of international collaboration, data sharing and open science to accelerate discovery in neurodegeneration research.", "doi": "10.1038/s41591-025-03834-0", "pmid": "40665048", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC12353841"}, {"db": "pii", "key": "10.1038/s41591-025-03834-0"}], "notes": [], "created": "2026-08-20T09:02:07.394Z", "modified": "2026-08-20T09:02:08.330Z"}, {"entity": "publication", "iuid": "5f981cbb10d5403baea20853de7d39ad", "links": {"self": {"href": "https://publications-affiliated.scilifelab.se/publication/5f981cbb10d5403baea20853de7d39ad.json"}, "display": {"href": "https://publications-affiliated.scilifelab.se/publication/5f981cbb10d5403baea20853de7d39ad"}}, "title": "Benchmarking the AI-based diagnostic potential of plasma proteomics for neurodegenerative disease in 17,170 people.", "authors": [{"family": "An", "given": "Lijun", "initials": "L", "orcid": "0000-0003-1030-4625", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/06744ec5a4ad4223b88038071e7b1dbf.json"}}, {"family": "Pichet-Binette", "given": "Alexa", "initials": "A", "orcid": "0000-0001-5218-3337", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/e8f0967b7b694bcf96e30a051a5bbe9a.json"}}, {"family": "Hristovska", "given": "Ines", "initials": "I"}, {"family": "Vilkaite", "given": "Gabriele", "initials": "G", "orcid": "0009-0009-6985-4307", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/fc705f5708ae447ea1ebd6a3a0bd73cf.json"}}, {"family": "Yu", "given": "Xiao", "initials": "X", "orcid": "0009-0006-6760-4134", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/49c14c0be1f2486bb835dd3090785268.json"}}, {"family": "Smets", "given": "Bart", "initials": "B"}, {"family": "Saloner", "given": "Rowan", "initials": "R", "orcid": "0000-0002-1351-6183", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/23de862940594622a28cb1e1c78b4447.json"}}, {"family": "Tasaki", "given": "Shinya", "initials": "S", "orcid": "0000-0003-3656-7394", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/741c7fb0f6044af6a9cae7b128972b10.json"}}, {"family": "Xu", "given": "Ying", "initials": "Y"}, {"family": "Krish", "given": "Varsha", "initials": "V"}, {"family": "Imam", "given": "Farhad", "initials": "F", "orcid": "0000-0003-2854-2568", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/a4b307d7379c43498446d995e26ef596.json"}}, {"family": "Janelidze", "given": "Shorena", "initials": "S", "orcid": "0000-0003-2869-8378", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/a3e2ab428bdc42838f5af521a4d8b862.json"}}, {"family": "van Westen", "given": "Danielle", "initials": "D", "orcid": "0000-0001-8649-9874", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/38afd81dca574f4a9884a1ce97b78e50.json"}}, {"family": "Global Neurodegeneration Proteomics Consortium (GNPC)", "given": "", "initials": ""}, {"family": "Stomrud", "given": "Erik", "initials": "E", "orcid": "0000-0002-0841-5580", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/ac36a615800c40b98d64369cb029497c.json"}}, {"family": "Whelan", "given": "Christopher D", "initials": "CD", "orcid": "0000-0003-0308-5583", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/172a710cb4974f168783a34e02eca6ee.json"}}, {"family": "Palmqvist", "given": "Sebastian", "initials": "S", "orcid": "0000-0002-9267-1930", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/6fbd05e87cfb4057a1a7e41d9fb94aef.json"}}, {"family": "Ossenkoppele", "given": "Rik", "initials": "R", "orcid": "0000-0003-1584-7477", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/9486d27ddd1b4b6485fa3ca10e0f3d82.json"}}, {"family": "Mattsson-Carlgren", "given": "Niklas", "initials": "N", "orcid": "0000-0002-8885-7724", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/bb26ae59b2a04f369c5ebc2f2375195a.json"}}, {"family": "Hansson", "given": "Oskar", "initials": "O", "orcid": "0000-0001-8467-7286", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/9292115deece4d9fafc8a02d4a430707.json"}}, {"family": "Vogel", "given": "Jacob W", "initials": "JW", "orcid": "0000-0001-6394-9940", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/d2ad5af780c245da9b59a8c80a0b00ff.json"}}], "type": "journal article", "published": "2025-07-01", "journal": {"title": "medRxiv", "issn-l": null}, "abstract": "Co-pathology is a common feature of neurodegenerative diseases that complicates diagnosis, treatment and clinical management.

Here, we present ProtAIDe-Dx, a deep joint-learning model trained on 17,170 patients and controls that uses plasma proteomics to provide simultaneous probabilistic diagnosis across six conditions associated with dementia in aging. ProtAIDe-Dx achieves cross-validated balanced classification accuracy of 69%-96% and AUCs > 79% across all conditions. The model's diagnostic probabilities highlighted subgroups of patients with co-pathologies, and were associated with pathology-specific biomarkers in an external sample, even among cognitively unimpaired people. Model interpretation revealed a suite of protein networks marking shared and specific biological processes across diseases, and identified novel and previously described proteins discriminating each diagnosis. ProtAIDe-Dx significantly improved biomarker-based differential diagnosis in a memory clinic sample, pinpointing proteins leading to diagnostic decisions at an individual level.
