Her symptoms emerged followed shortly after discontinuation of risperidone, an atypical antipsychotic previously commenced to manage disruptive behaviour associated with ASD. On physical examination, the patient presented with negativism, grimacing, automatic obedience, waxy flexibility and ambitendency. Blood tests, neuroimaging and lumbar puncture failed to reveal an acute infectious or neurological precipitant. She responded immediately to a trial of intramuscular lorazepam titrated to a total daily dose of 12\u2009mg. This case presents challenges of accurately diagnosing and managing catatonic symptoms in adolescent patients with ASD. We also discuss the potential risk of precipitating catatonia following the discontinuation of antipsychotic treatment that has been prescribed for a prolonged duration.<\/jats:p>","DOI":"10.1136\/bcr-2020-240785","type":"journal-article","created":{"date-parts":[[2021,4,23]],"date-time":"2021-04-23T10:45:24Z","timestamp":1619174724000},"page":"e240785","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Case of paediatric catatonia precipitated by antipsychotic withdrawal in a child with autism spectrum disorder"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3374-7069","authenticated-orcid":false,"given":"Mohd","family":"Faisal","sequence":"first","affiliation":[{"name":"Department of Psychiatry, University Hospital Limerick, Limerick, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vishnu","family":"Pradeep","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, University Hospital Limerick, Limerick, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susan","family":"O'Hanrahan","sequence":"additional","affiliation":[{"name":"Child and Adolescent Mental Health Services, Unit 6 Quin Road Business Park, Ennis, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,4,23]]},"reference":[{"key":"2025082712205861000_14.4.e240785.1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0447.2011.01778.x"},{"key":"2025082712205861000_14.4.e240785.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.schres.2009.04.021"},{"key":"2025082712205861000_14.4.e240785.3","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1038\/s41398-018-0192-9","article-title":"Review of withdrawal catatonia: what does this reveal about clozapine?","volume":"8","author":"Lander","year":"2018","journal-title":"Transl Psychiatry"},{"key":"2025082712205861000_14.4.e240785.4","doi-asserted-by":"crossref","first-page":"S109","DOI":"10.1016\/j.jagp.2017.01.123","article-title":"Catatonia secondary to olanzapine discontinuation: a dramatic decline and a dramatic response","volume":"25","author":"Waserstein","year":"2017","journal-title":"Am J Geriatr Psychiatry"},{"key":"2025082712205861000_14.4.e240785.5","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1155\/2017\/2402731","article-title":"Catatonia secondary to sudden clozapine withdrawal: a case with three repeated episodes and a literature review","volume":"2017","author":"Bilbily","year":"2017","journal-title":"Case Rep Psychiatry"},{"key":"2025082712205861000_14.4.e240785.6","doi-asserted-by":"publisher","DOI":"10.1016\/j.schres.2005.01.014"},{"key":"2025082712205861000_14.4.e240785.7","doi-asserted-by":"publisher","DOI":"10.1046\/j.1440-1614.2003.01125.x"},{"key":"2025082712205861000_14.4.e240785.8","doi-asserted-by":"publisher","DOI":"10.1192\/bjp.176.4.357"},{"key":"2025082712205861000_14.4.e240785.9","doi-asserted-by":"crossref","unstructured":"Takaoka K , Takata T .
