Predictive value of individual serum neurofilament light chain levels in short-term disease activity in relapsing multiple sclerosis.

Background: The assessment of serum neurofilament light chain (sNFL) has emerged as a diagnostic and prognostic tool in monitoring multiple sclerosis (MS). However, the application of periodic measurement in daily practice remains unclear.

Objective: To evaluate the predictive value of individual sNFL levels in determining disease activity in patients with relapsing MS (RMS).
