Plasma NFL levels are correlated with motor severity and progression in patients with MSA, but not with cognitive progression. It can serve as a reliable biomarker for monitoring the disease severity and progression of MSA.
Background Neurofilament light chain (NFL), a potential biomarker of multiple system atrophy (MSA), has been reported in several studies. Objectives The objective of this study was to investigate whether plasma NFL levels are correlated with the progression of motor and cognition function in MSA. Methods Patients with MSA were part of a prospective cohort study with assessments at baseline and after 1 year. Plasma NFL was quantified using ultrasensitive Simoa technology. Results A total of 91 patients with MSA and 60 healthy controls (HCs) were enrolled. NFL levels increased from baseline to 1-year follow-up (P = 0.010). Baseline plasma NFL levels were significantly associated with motor severity and progression in patients with MSA (P < 0.05) but not with cognitive progression (P > 0.05). Conclusions Plasma NFL is a reliable biomarker for the disease severity of MSA and monitoring the progression of MSA, but not the progression of cognition.
