title: Anti-N-methyl-D-aspartate encephalitis - a case study of symptomatic progression.
abstract: OBJECTIVE
  To present the diagnosis course and sequelae of a case of anti-N-methyl-D-aspartate (NMDA) receptor encephalitis, drawing attention to early psychiatric symptoms.
  
  
  METHODS
  The literature on anti-NMDA encephalitis is reviewed and possible psychopathological mechanisms discussed.
  
  
  RESULTS
  New onset psychoses, presenting with the combination of hallucinations, dyskinesias and seizures and progressing to catatonia should be referred to neurology for consideration of anti-NMDA receptor encephalitis.
  
  
  CONCLUSIONS
  Early diagnosis is important for a favourable prognosis.
