Autoimmune encephalitides

Autoimmune limbic encephalitides (LE) and encephalitis with antibodies against glutamate NMDA receptors (NMDAR encephalitis) are important subtypes of autoimmune encephalitis. LE are characterised by the presence of subacute-onset memory impairment, epileptic seizures and psychiatric symptoms. Autoantibodies associated with LE may be directed either against intracellular or membrane-bound antigens and the nature of clinical symptoms, findings of supplementary methods, effect of immunotherapy and prognosis are largely determined by the type of associated antibody. NMDAR encephalitis is a diffuse cortical autoimmune encephalitis. It is relatively common, occurs predominantly in young females and children, has a characteristic build-up of clinical symptoms and usually requires long hospital stays and intensive care support. Nevertheless, with timely and aggressive immunotherapy, NMDAR encephalitis is a reversible disorder. Early diagnosis and treatment is the key factor for outcome in patients with NMDAR encephalitis and limbic encephalitis.
