Early in the disease course, patients often present with marked psychosis and mood disturbances (i.e. mania, depression), explaining why most of these patients are first seen by psychiatrists. Hence, autoimmune encephalitis is receiving growing attention from psychiatry, mainly owing to concerns over misdiagnosing immunomediated and potentially curable disorders as primary psychiatric disorders, such as schizophrenia or major depressive disorder. Although anti-NMDAR encephalitis occurs in the context of new-onset psychiatric symptoms, there is a lack of information on differential diagnosis and treatment of this disorder after a long-term diagnostic history of functional psychiatric disorders. We report a case of a patient with a long history of bipolar affective disorder evolving with anti-NMDAR encephalitis, initially misdiagnosed as non-organic psychosis.<\/jats:p>","DOI":"10.1590\/1980-57642015dn93000016","type":"journal-article","created":{"date-parts":[[2015,9,29]],"date-time":"2015-09-29T20:14:02Z","timestamp":1443557642000},"page":"311-314","source":"Crossref","is-referenced-by-count":8,"title":["A patient with a long history of relapsing psychosis and mania presenting with anti-NMDA receptor encephalitis ten years after first episode"],"prefix":"10.1590","volume":"9","author":[{"given":"Mateus Mistieri","family":"Simabukuro","sequence":"first","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian Henrique de Andrade","family":"Freitas","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luiz Henrique Martins","family":"Castro","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","reference":[{"key":"ref1","first-page":"1437","article-title":"Anti-N-methyl-d-aspartate receptor encephalitis in a patient with a 7-year history of being diagnosed as schizophrenia: complexities in diagnosis and treatment","volume":"11","author":"Huang C","year":"2015","journal-title":"Neuropsychiatr Dis Treat"},{"key":"ref2","article-title":"Anti-NMDA receptor encephalitis, autoimmunity, and psychosis","author":"Kayser MS","year":"2015","journal-title":"Schizophr Res [Internet]"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"157","DOI":"10.1016\/S1474-4422(12)70310-1","article-title":"Treatment and prognostic factors for long-term outcome in patients with anti-NMDA receptor encephalitis: an observational cohort study","volume":"12","author":"Titulaer MJ","year":"2013","journal-title":"Lancet Neurol"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"1133","DOI":"10.1001\/jamaneurol.2013.3216","article-title":"Frequency and Characteristics of Isolated Psychiatric Episodes in Anti-N-Methyl- D-Aspartate Receptor Encephalitis","volume":"70","author":"Kayser MS","year":"2013","journal-title":"JAMA Neurol"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"94","DOI":"10.1111\/nyas.12553","article-title":"Autoimmune encephalopathies","volume":"1338","author":"Leypoldt F","year":"2015","journal-title":"Ann N Y Acad Sci"},{"key":"ref6","doi-asserted-by":"crossref","first-page":"504","DOI":"10.1212\/01.wnl.0000278388.90370.c3","article-title":"Anti-NMDA receptor encephalitis in Japan: long-term outcome without tumor removal","volume":"70","author":"Iizuka T","year":"2008","journal-title":"Neurology"},{"key":"ref7","doi-asserted-by":"crossref","first-page":"686","DOI":"10.1007\/s00415-010-5788-9","article-title":"Disease-relevant autoantibodies in first episode schizophrenia","volume":"258","author":"Zandi MS","year":"2011","journal-title":"J Neurol"}],"container-title":["Dementia &amp; Neuropsychologia"],"original-title":[],"link":[{"URL":"http:\/\/www.scielo.br\/pdf\/dn\/v9n3\/1980-5764-dn-9-03-00311.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,11,4]],"date-time":"2017-11-04T18:00:40Z","timestamp":1509818440000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.scielo.br\/scielo.php?script=sci_arttext&pid=S1980-57642015000300311&lng=en&tlng=en"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,9]]},"references-count":7,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2015,9]]}},"alternative-id":["S1980-57642015000300311"],"URL":"https:\/\/doi.org\/10.1590\/1980-57642015dn93000016","relation":{},"ISSN":["1980-5764"],"issn-type":[{"value":"1980-5764","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,9]]}}}
