Why Anti-NMDA receptor encephalitis? Anti-NMDA receptor antibody encephalitis has been described to occur in a multistage process (Reference Irani, Bera and Waters Irani 2010b), although this may not always be the case in all patients. Background Anti-NMDA receptor (NMDAR) encephalitis is a recently characterised autoimmune disorder mainly affecting young women. Despite the rarity of this case (to our knowledge, it is the first case of this type to be reported), production of anti-NMDAR antibodies may be explained by the antigenic stimulus of the virus, which would trigger the disease. Anti-NMDA receptor encephalitis commonly begins with a prodromal phase characterized by headache, malaise, and flu-like symptoms. 1 It is a form of autoimmune encephalitis targeted against the NR1 subunit of the NMDA receptor (N-methyl D-aspartate receptor).
