Abstract

OBJECTIVE: Anti-N-methyl-D-Aspartate encephalitis is a recently diagnosed autoimmune disorder with increasing significance. During this disease antibodies are produced against the subunit of the NMDA receptor, which cause different symptoms, both psychiatric and neurological. The aim of this publication is to introduce this disease, to facilitate the diagnosis and to recommend therapeutical guideline.

MATERIALS AND METHODS: In this review we summarized the relevant literature published between 2007 and 2015 giving emphasis on etiopathogenesis, diagnosis, differential diagnosis, treatment and prognosis.

RESULTS: In the etiology an underlying tumor or a viral agent should be considered. During the disease we can discern 3 periods: first prodromal viral infections-like symptoms can be seen, 1-2 weeks later psychiatric symptoms, such as aggression, sleep and behavior disturbances appear. After that neurological symptoms (tonic-clonic convulsions, aphasia, catatonia, orofacial dyskinesia, autonom lability, altered mental state) are typical, and the patient's condition deteriorates. For the correct diagnosis it is necessary to detect antibodies against the NMDA receptor from the serum and the liquor. Steroids, immunoglobulins and plasmaheresis are the first-line therapies. If the disease is unresponsive, then as a second-line therapy anti-CD 20 (Rituximab) and cyclophosphamid can be useful. Most of the patients are improving without any neurological sequale with prompt detection and appropriate therapy.

CONCLUSION: It is important to be familiar with the symptoms, diagnosis and therapy of this disease as a practicing clinician, especially as a psychiatrist or neurologist. 75 percentage of the patients are admitted to psychiatric departments first because of the leading symptoms. Autoimmune NMDA encephalitis is a reversible disease after early diagnosis and treatment.
