Catatonia in Anti-N-Methyl-D-Aspartate (NMDA) Receptor Encephalitis Misdiagnosed as Schizophrenia.

We report the diagnostic investigation of a case of anti-N-methyl-D-aspartate receptor encephalitis in a patient with a previous diagnosis of schizophrenia with poor response to antipsychotics. The aim of this case report is to highlight the importance of close surveillance for neuropsychiatric symptoms, especially catatonia, and to recognize autoimmune encephalitis in the differential diagnosis of psychotic disorders with neurological symptoms and resistance or intolerance to antipsychotics. A prompt diagnosis will contribute to a faster onset of therapy and an overall improvement in prognosis. PMID: 32130101 [PubMed - as supplied by publisher]
