Moreover, herpervirus encephalitis can evaluated to autoimmune encephalitis associated to antibodies to the receptor of N-methyl-D-Aspartate (NMDA) [12], and recently registers showed that COVID-19 infection can also be followed by autoimmune encephalitis mediated by antibodies to glycoprotein (Ab-GAD) or to MOGAD disease [13,14,15]. Here, ART4 is linked to autoimmune encephalitis.
