Owing to similar clinical symptoms, he had been misdiagnosed with schizophrenia. This had led to a placement in a facility for persons with chronic schizophrenia, antipsychotic pharmacotherapy for 4\u2005years and side effects, including substantial weight gain and hypertension. After cessation of the antipsychotic medication, the weight and blood pressure normalised. We started a prophylactic treatment with lithium under which the patient had become asymptomatic and had been able to begin a vocational training since treatment.<\/jats:p>","DOI":"10.1136\/bcr-2013-009373","type":"journal-article","created":{"date-parts":[[2013,7,9]],"date-time":"2013-07-09T02:13:24Z","timestamp":1373336004000},"page":"bcr2013009373","source":"Crossref","is-referenced-by-count":3,"title":["Sleep-related psychosis"],"prefix":"10.1136","volume":"2013","author":[{"given":"Lukas","family":"Frase","sequence":"first","affiliation":[{"name":"Department of Psychiatry and Psychotherapy, University Medical Center Freiburg, Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara","family":"Sixt","sequence":"additional","affiliation":[{"name":"Outpatient Unit for Child and Adolescent Psychiatry, Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph","family":"Nissen","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Psychotherapy, University Medical Center Freiburg, Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2013,7,8]]},"reference":[{"key":"2025082707251821000_2013.jul08_1.bcr2013009373.1","doi-asserted-by":"crossref","first-page":"2763","DOI":"10.1093\/brain\/awh620","article-title":"Kleine-Levin syndrome: a systematic review of 186 cases in the literature","volume":"2013","author":"Arnulf","year":"2005","journal-title":"Brain"},{"key":"2025082707251821000_2013.jul08_1.bcr2013009373.2","doi-asserted-by":"crossref","first-page":"628","DOI":"10.1016\/j.jocn.2011.08.020","article-title":"Distribution of HLA-DQB1 alleles in patients with Kleine-Levin syndrome","volume":"2013","author":"Huang","year":"2012","journal-title":"J Clin Neurosci"},{"key":"2025082707251821000_2013.jul08_1.bcr2013009373.3","doi-asserted-by":"crossref","first-page":"1739","DOI":"10.1212\/01.WNL.0000036605.89977.D0","article-title":"Kleine-Levin syndrome: an autoimmune hypothesis based on clinical and genetic analyses","volume":"2013","author":"Dauvilliers","year":"2002","journal-title":"Neurology"},{"key":"2025082707251821000_2013.jul08_1.bcr2013009373.4","doi-asserted-by":"crossref","first-page":"482","DOI":"10.1002\/ana.21333","article-title":"Kleine-Levin syndrome: a systematic study of 108 patients","volume":"2013","author":"Arnulf","year":"2008","journal-title":"Ann Neurol"},{"key":"2025082707251821000_2013.jul08_1.bcr2013009373.5","doi-asserted-by":"crossref","unstructured":"Oliveira MM Conti C Saconato H . \u00a0Pharmacological treatment for Kleine-Levin syndrome.
