Scientists identify two new multiple sclerosis subtypes

Scientists have identified two new biological subtypes of Multiple Sclerosis (MS) using AI, a blood test, and MRI scans. This breakthrough could revolutionize MS treatment worldwide. The research, involving 600 patients, detected "early sNfL" and "late sNfL" subtypes. Early sNfL appears more aggressive with rapid damage, while late sNfL shows slower progression with initial brain shrinkage. This discovery allows for more precise risk assessment and personalized treatment strategies, moving beyond current clinical symptom-based classifications of MS.
