Going forward, we need to assess the burden of childhood encephalitis caused by anti-NMDA receptor encephalitis in Vietnam as a priority, and complement this study with a panel of assays searching for other antibodies against neuronal cell surface antigens including AMPAR, GABAbR, GABAaR, LGT1 and Caspr2, to help improve understanding of the epidemiology and management of non-infectious encephalitis in the region. Here, CNTNAP2 is linked to encephalitis.
