He had discontinued clozapine approximately 1\u2009month before presenting to the emergency department displaying signs of psychosis, with generalised choreiform and dystonic movements. Urinary toxicology was positive for cocaine. Clozapine treatment was reinitiated, and within 2 weeks the dyskinesia had subsided. Review of his records revealed two previous episodes of similar dyskinesia, both of which were temporally associated with cocaine use. Dyskinesia occurring in the context of cocaine use, and clozapine withdrawal-associated dyskinesia were considered to be the main differential diagnoses. A range of differential diagnoses should be considered in patients presenting with an acute-onset movement disorder who have a history of long-term exposure to antipsychotic medication.<\/jats:p>","DOI":"10.1136\/bcr-2018-225251","type":"journal-article","created":{"date-parts":[[2018,12,18]],"date-time":"2018-12-18T17:19:47Z","timestamp":1545153587000},"page":"e225251","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Acute dyskinesia in a patient with schizophrenia"],"prefix":"10.1136","volume":"11","author":[{"given":"Alex James","family":"Berry","sequence":"first","affiliation":[{"name":"Department of Psychiatry, Camden and Islington NHS Foundation Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2018,12,9]]},"reference":[{"key":"2025082710321978000_11.1.e225251.1","doi-asserted-by":"publisher","DOI":"10.1136\/pn.2007.134585"},{"key":"2025082710321978000_11.1.e225251.2","doi-asserted-by":"publisher","DOI":"10.4088\/JCP.v59n0906"},{"key":"2025082710321978000_11.1.e225251.3","doi-asserted-by":"crossref","first-page":"35","DOI":"10.1016\/j.jns.2018.02.005","article-title":"Tardive syndromes","volume":"389","author":"Savitt","year":"2018","journal-title":"J Neurol Sci"},{"key":"2025082710321978000_11.1.e225251.4","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuropharm.2014.06.012"},{"key":"2025082710321978000_11.1.e225251.5","doi-asserted-by":"crossref","first-page":"751","DOI":"10.1212\/WNL.44.4.751","article-title":"Cocaine-induced choreoathetoid movements (\u2019crack dancing')","volume":"44","author":"Daras","year":"1994","journal-title":"Neurology"},{"key":"2025082710321978000_11.1.e225251.6","doi-asserted-by":"publisher","DOI":"10.1016\/S0006-3223(98)00238-8"},{"key":"2025082710321978000_11.1.e225251.7","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870080210"},{"key":"2025082710321978000_11.1.e225251.8","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.65.4.436"},{"key":"2025082710321978000_11.1.e225251.9","doi-asserted-by":"crossref","first-page":"964","DOI":"10.1212\/WNL.56.7.964","article-title":"Cocaine-induced persistent dyskinesias","volume":"56","author":"Weiner","year":"2001","journal-title":"Neurology"},{"key":"2025082710321978000_11.1.e225251.10","doi-asserted-by":"crossref","first-page":"pp5","DOI":"10.64719\/pb.4321","article-title":"Cocaine is a major risk factor for antipsychotic induced akathisia, parkinsonism and dyskinesia","volume":"41","author":"Maat","year":"2008","journal-title":"Psychopharmacol Bull"},{"key":"2025082710321978000_11.1.e225251.11","doi-asserted-by":"publisher","DOI":"10.1097\/FTD.0b013e3181f2b729"},{"key":"2025082710321978000_11.1.e225251.12","doi-asserted-by":"crossref","first-page":"1190","DOI":"10.1002\/mds.21430","article-title":"Crack dancing in the United Kingdom: apropos a video case presentation","volume":"22","author":"Kamath","year":"2007","journal-title":"Mov Disord"},{"key":"2025082710321978000_11.1.e225251.13","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bdj.2008.244"},{"key":"2025082710321978000_11.1.e225251.14","doi-asserted-by":"crossref","first-page":"1626e","DOI":"10.1176\/ajp.155.11.1626e","article-title":"Cocaine and catatonia","volume":"155","author":"Gingrich","year":"1998","journal-title":"Am J Psychiatry"},{"key":"2025082710321978000_11.1.e225251.15","doi-asserted-by":"publisher","DOI":"10.1016\/0006-3223(95)00082-8"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/data.bmj.org\/tdm\/10.1136\/bcr-2018-225251","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2018-225251","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,4]],"date-time":"2026-04-04T16:13:26Z","timestamp":1775319206000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2018-225251"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,11]]},"references-count":15,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2018,12,9]]},"published-print":{"date-parts":[[2018,11]]}},"alternative-id":["10.1136\/bcr-2018-225251"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2018-225251","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,11]]}}}
