This research aims to uncover the causal relationships between cerebrospinal fluid metabolites and neuromyelitis optica spectrum disorder (NMOSD).
Conducted Mendelian randomization analyses to estimate roles of CSF metabolites in NMOSD.
Stringently selected instrumental variables to minimize confounding effects.
Performed comprehensive sensitivity analyses to validate findings.
Specific glycerophosphocholine species linked to risk in both AQP4-IgG positive and negative NMOSD.
Ascorbate and N-acetylhexosamines showed protective effects across subtypes.
No evidence of heterogeneity or horizontal pleiotropy found in MR analyses.
