21 -The classification and diagnosis of central nervous system (CNS) diseases have long been constrained by traditional phenotype-based approaches, which often fail to capture the complex pathophysiological mechanisms, molecular biomarkers, and neuroanatomical changes that drive disease progression. Neurodegenerative and psychiatric disorders, for example, exhibit significant clinical overlap, co-pathology, and heterogeneity, making current diagnostic models insufficient.
21 +== How to Contribute: ==
22 22  
23 -This project proposes a new diagnostic framework—one that shifts from symptom-based classifications to an etiology-driven, tridimensional system. By integrating genetics, proteomics, neuroimaging, computational modeling, and AI-powered annotations, this approach aims to provide a more precise, scalable, and biologically grounded method for diagnosing and managing CNS diseases.
24 -
25 -The AI-powered annotation system plays a critical role by structuring, interpreting, and tracking multi-modal data, ensuring real-time disease progression analysis, clinician decision support, and personalized treatment pathways.
26 -
27 -=== **Project Aim** ===
28 -
29 -Neurodiagnoses is an open-source AI-powered diagnostic system designed for complex central nervous system (CNS) disorders, including neurodegenerative diseases, autoimmune encephalopathies, prion disorders, and genetic syndromes. The project aims to develop a tridimensional diagnostic framework with an AI-powered annotation system, integrating etiology, molecular biomarkers, and neuroanatomoclinical correlations for precise, standardized, and scalable CNS disease diagnostics.
30 -
31 -The //Tridimensional Diagnostic Framework// redefines CNS diseases can be classified and diagnosed by focusing on:
32 -
33 -* **Axis 1**: Etiology (genetic or other causes of diseases).
34 -* **Axis 2**: Molecular Markers (biomarkers).
35 -* **Axis 3**: Neuroanatomoclinical correlations (linking clinical symptoms to structural changes in the nervous system).
36 -
37 -This methodology enables:
38 -
39 -* Greater precision in diagnosis.
40 -* Integration of incomplete datasets using AI-driven probabilistic modeling.
41 -* Stratification of patients for personalized treatment.
42 -
43 -== **The Role of AI-Powered Annotation** ==
44 -
45 -To enhance standardization, interpretability, and clinical application, the framework integrates an AI-powered annotation system, which:
46 -
47 -* Assigns structured metadata tags to diagnostic features.
48 -* Provides real-time contextual explanations for AI-based classifications.
49 -* Tracks longitudinal disease progression using timestamped AI annotations.
50 -* Improves AI model transparency through interpretability tools (e.g., SHAP analysis).
51 -* Facilitates decision-making for clinicians by linking annotations to standardized biomedical ontologies (SNOMED, HPO).
52 -
53 -Neurodiagnoses provides two complementary AI-driven diagnostic approaches:
54 -
55 -1. Traditional Probabilistic Diagnosis
56 -
57 -* AI provides multiple possible diagnoses, each assigned a probability percentage based on biomarker, imaging, and clinical data.
58 -* Example Output:
59 -
60 ->
61 -
62 -{{{75% Alzheimer's Disease
63 -20% Lewy Body Dementia
64 -5% Vascular Dementia
65 -}}}
66 -
67 -* Useful for differential diagnosis and treatment decision-making.
68 -
69 -2. Tridimensional Diagnosis
70 -
71 -* Diagnoses are structured based on:
72 -(1) Etiology (genetic, autoimmune, metabolic, infectious)
73 -(2) Molecular Biomarkers (amyloid-beta, tau, inflammatory markers, EEG patterns)
74 -(3) Neuroanatomoclinical Correlations (brain atrophy, connectivity alterations)
75 -* This approach enables precise disease subtyping and biologically meaningful classification.
76 -
77 -For every patient case, both systems will be offered, allowing clinicians to compare AI-generated probabilistic diagnosis with a structured tridimensional classification.
78 -
79 -
80 -== **The case of neurodegenerative diseases** ==
81 -
82 -There have been described these 3 diagnostic axes:
83 -
84 -[[Neurodegenerative diseases can be studied and classified in a tridimensional scheme with three axes: anatomic–clinical, molecular, and etiologic. CSF, cerebrospinal fluid; FDG, fluorodeoxyglucose; MRI, magnetic resonance imaging; PET, positron emission tomography.>>image:tridimensional.png||alt="tridimensional view of neurodegenerative diseases"]]
