| 1 | **Neurodiagnoses AI** is an open-source, AI-driven framework designed to enhance the diagnosis and prognosis of central nervous system (CNS) disorders. Building upon the Florey Dementia Index (FDI) methodology, it now encompasses a broader spectrum of neurological conditions. The system integrates multimodal data sources—including EEG, neuroimaging, biomarkers, and genetics—and employs machine learning models to deliver explainable, real-time diagnostic insights. A key feature of this framework is the incorporation of the **Generalized Neuro Biomarker Ontology Categorization (Neuromarker)**, which standardizes biomarker classification across all neurodegenerative diseases, facilitating cross-disease AI training. | ||

| 3 | **Neuromarker: Generalized Biomarker Ontology** | ||
| 4 | |||
| 5 | Neuromarker extends the Common Alzheimer’s Disease Research Ontology (CADRO) into a comprehensive biomarker categorization framework applicable to all neurodegenerative diseases (NDDs). This ontology enables standardized classification, AI-based feature extraction, and seamless multimodal data integration. | ||

| 7 | **Core Biomarker Categories** | ||
| 8 | |||
| 9 | Within the Neurodiagnoses AI framework, biomarkers are categorized as follows: | ||
| 10 | |||
| 11 | |=**Category**|=**Description** | ||
| 12 | |**Molecular Biomarkers**|Omics-based markers (genomic, transcriptomic, proteomic, metabolomic, lipidomic) | ||
| 13 | |**Neuroimaging Biomarkers**|Structural (MRI, CT), Functional (fMRI, PET), Molecular Imaging (tau, amyloid, α-synuclein) | ||
| 14 | |**Fluid Biomarkers**|CSF, plasma, blood-based markers for tau, amyloid, α-synuclein, TDP-43, GFAP, NfL, autoantiboides | ||
| 15 | |**Neurophysiological Biomarkers**|EEG, MEG, evoked potentials (ERP), sleep-related markers | ||
| 16 | |**Digital Biomarkers**|Gait analysis, cognitive/speech biomarkers, wearables data, EHR-based markers | ||
| 17 | |**Clinical Phenotypic Markers**|Standardized clinical scores (MMSE, MoCA, CDR, UPDRS, ALSFRS, UHDRS) | ||
| 18 | |**Genetic Biomarkers**|Risk alleles (APOE, LRRK2, MAPT, C9orf72, PRNP) and polygenic risk scores | ||
| 19 | |**Environmental & Lifestyle Factors**|Toxins, infections, diet, microbiome, comorbidities | ||
