We collected clinical data of patients with anti-NMDAR encephalitis, including age, gender, situation of the combined precursor infection, duration of duration, maximum mRS score in the acute phase, mRS score at 3 months’ follow-up, NEOS score, CSF leukocyte count and protein levels, CSF antibody titer, and brain MRI and EEG, and then correlation analysis was performed between these data and cIAP-1, MCSF, CXCL13, and NLRP3 levels in CSF. Here, CXCL13 is linked to infection.
