Study Identifies Two Biological Pathways In MS
Researchers at University College London and Queen Square Analytics publish a study in Brain analyzing combined MRI and serum neurofilament light chain (sNfL) data from 634 people with MS, identifying two distinct biological subtypes. One subtype shows early cortical damage and slower decline, while the other shows predominant white-matter degeneration and faster progression. The split may explain variable treatment responses and enable earlier biology-driven patient stratification.
Key Points
- 1Detects two distinct MS subtypes using MRI and sNfL in 634 patients
- 2Reveals divergent neurodegeneration patterns—cortical-dominant versus white-matter-dominant—linked to different progression rates
- 3Suggests subtype-specific prognosis and treatment response, enabling earlier stratification using biomarkers and imaging
Scoring Rationale
Strong peer-reviewed evidence and clear subtype finding, limited by single-cohort and need for broader validation.
