Other postinfectious syndromes are believed to be driven more by specific autoantibodies such as the movement disorder, anti-N-methyl-d-aspartate receptor encephalitis targeting the N-methyl-d-aspartate receptor (46), or acute disseminated encephalitis, a multiple sclerosis–like syndrome characterized by widespread inflammation in the brain and spinal cord following a viral or bacterial infection accompanied by perivenous demyelination linked to antibodies to native myelin oligodendrocyte glycoprotein (47). The gene discussed is OMG; the disease is movement disorder.
