LGI1 and viral encephalitis: (Fig. 2B) At discharge, there was a significant difference in mRS between ivMP mono (median mRS 2; 0–5) and ivMP + PE + IVIG (median mRS 3; 0–6; p = 0,0287) for anti-NMDAR encephalitis; for encephalitis caused by antibodies against LGI1 and CASPR2, no significant differences in mRS were seen between treatment groups.
