AB  - Encephalitis related to antibodies against the N-methyl-D-aspartate receptor 
      (NMDAr) is a recently described clinical entity in which IgG autoantibodies 
      against the NR1 subunit of the NMDAr lead to the appearance of complex 
      neuropsychiatric symptoms. As psychiatric symptoms predominate in early stages, 
      anti-NMDAr encephalitis is frequently mistaken as a primary psychiatric disorder 
      which delays treatment and has serious consequences for patients. This report 
      presents the case of a 24-year-old woman with a subacute onset of psychotic and 
      catatonic symptoms in whom current diagnostic criteria for probable anti-NMDAr 
      encephalitis were not fulfilled. On the basis of the red flags that have been 
      proposed to raise suspicion of anti-NMDAr encephalitis, a study of 
      fluorodeoxyglucose positron emission tomography was requested and demonstrated 
      bilateral occipital hypometabolism consistent with clinical suspicion of 
      anti-NMDAr encephalitis. Once the appropriate treatment was established, the 
      patient recovered completely. This case supports the need to maintain clinical 
      suspicion of anti-NMDAr encephalitis, even when conventional diagnostic tests 
      have been normal. Psychiatrists should be familiar with this entity to promote 
      timely diagnosis and prompt treatment.
