Recently, the search for diagnostic antibody markers has drawn considerable attention in relation to autoimmune encephalitis. Among the antibody markers, the most frequently detected is the anti-N-methyl-D-aspartate receptor (NMDAR)antibody. Patients with this antibody develop characteristic clinical features. ⋯ It is important to test the anti-NMDAR antibody in these groups since immunotherapy ameliorates their symptoms. The anti-NMDAR antibody binds to the constitutional epitope at the extracellular domain of GluN1 and disrupts its function. Early introduction of immunotherapy together with tumor resection will results in improvement of neurological symptoms.
