Integrating Big Data and Artificial Intelligence to Predict Progression in Multiple Sclerosis: Challenges and the Path Forward
This analysis explores how AI and big data can revolutionize personalized care for Multiple Sclerosis (MS) by predicting disease progression. It highlights the current challenges in multimodal data integration, regulatory hurdles, and ethical concerns, while proposing a structured path forward through federated learning, data standardization, and patient-centric design.
Executive Impact Summary
Multiple Sclerosis (MS) is a complex and costly neurological condition where early detection and accurate prognosis of disease progression are crucial but challenging. Artificial intelligence (AI) combined with big data offers transformative potential for personalized MS care, yet its integration faces significant barriers. These include fragmented real-world data (RWD), methodological constraints, evolving regulatory frameworks like the EU AI Act and MDR, and ethical concerns regarding bias, privacy, and equity. Current AI applications often rely on single modalities, like MRI, limiting their predictive power. The 'clinico-radiological paradox' further complicates traditional MRI assessments, as visible lesions don't always correlate with clinical symptoms. Emerging solutions, such as radiomics, multimodal integration of MRI, EHRs, and digital biomarkers from wearables, show promise. The paper advocates for a structured path forward involving harmonized data infrastructures, federated learning, patient-centered design, explainable AI, and real-world validation to overcome these challenges and enable meaningful clinical adoption, ultimately improving outcomes for people with MS.

0.84
AUROC: Vision Transformer models using longitudinal spinal cord MRI achieved an AUROC of 0.84 for 6-year prediction of disability progression.
Federated Learning for MS Research
Scenario: A global consortium aims to leverage federated learning for MS research without centralizing patient data. By training AI models on distributed datasets across multiple hospitals, only model updates are shared, preserving data confidentiality.
Challenge: Fragmented data across diverse registries, ethical concerns, and regulatory demands prevent direct sharing of raw patient data.
Solution: A 3-layer federated analysis pipeline (Pirmani et al., 2023) enables multi-site collaboration. This approach trains lesion segmentation algorithms across centers while keeping raw data local.
Outcome: More robust AI models, reduced bias from single-center training, and adherence to privacy regulations, paving the way for scalable, privacy-preserving MS research.

Digital Hospital-at-Home for MS
Scenario: To transform long-term MS care, a 'digital hospital-at-home' model integrates PROs, wearable-derived metrics (gait, cognition), and cloud-hosted imaging data into AI-powered dashboards for continuous disease management.
Challenge: Patient adoption concerns due to perceived intrusiveness, need for clear consent, and robust governance. Requires national reimbursement frameworks and equitable broadband access.
Solution: Develop patient-centered AI systems that prioritize patient outcomes, ensuring transparency and trust. Implement open-source toolkits and global minimum-dataset standards to ensure affordability and interoperability across diverse economic settings.
Outcome: Potential for continuous, real-time disease management, earlier detection of changes, and truly personalized care, reducing reliance on episodic clinic-centered follow-ups.
