are consistent with our results observing no correlation between cNfL and IgG quotient or CSF cell count in a small (n = 6) anti‐N‐methyl‐D‐aspartate receptor (NMDAR) encephalitis patient cohort [8] and an AE patient cohort consisting of anti‐NMDAR encephalitis (n = 37) and anti‐leucine‐rich glioma inactivated 1 (LGI1) encephalitis (n = 16) patients [16]. This evidence concerns the gene LGI1 and viral encephalitis.
