Postinjury, bilateral chorea rendered him dependent for all activities of daily living. Risperidone provided a significant reduction of chorea, decreasing the overall burden of care. Movement disorders are a common sequela of brain injury. Currently, there are no best treatment guidelines for chorea in patients with brain injury. To the authors\u2019 knowledge there have been no case reports describing the effects of brain injury on patients with a primary movement disorder. Risperidone was an effective treatment in this case. Further research is needed to establish guidelines for treatment of movement disorders following brain injury and to better understand the effect of brain injuries on primary movement disorders.<\/jats:p>","DOI":"10.1136\/bcr-2021-241929","type":"journal-article","created":{"date-parts":[[2021,5,19]],"date-time":"2021-05-19T13:46:55Z","timestamp":1621432015000},"page":"e241929","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Bilateral chorea following severe traumatic brain injury treated with risperidone"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8555-8289","authenticated-orcid":false,"given":"Daniel","family":"Krasna","sequence":"first","affiliation":[{"name":"Physical Medicine and Rehabilitation, Moss Rehabilitation Hospital, Elkins Park, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erica","family":"Montgomery","sequence":"additional","affiliation":[{"name":"Physical Medicine and Rehabilitation, Moss Rehabilitation Hospital, Elkins Park, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacob","family":"Koffer","sequence":"additional","affiliation":[{"name":"Physical Medicine and Rehabilitation, Moss Rehabilitation Hospital, Elkins Park, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miriam","family":"Segal","sequence":"additional","affiliation":[{"name":"Physical Medicine and Rehabilitation, Moss Rehabilitation Hospital, Elkins Park, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,5,19]]},"reference":[{"key":"2025082709461341000_14.5.e241929.1","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-200205000-00003"},{"key":"2025082709461341000_14.5.e241929.2","doi-asserted-by":"crossref","first-page":"1488","DOI":"10.1212\/WNL.47.6.1488","article-title":"Post-Traumatic movement disorders in survivors of severe head injury","volume":"47","author":"Krauss","year":"1996","journal-title":"Neurology"},{"key":"2025082709461341000_14.5.e241929.3","doi-asserted-by":"crossref","unstructured":"Fhan S , Jankovic J , Hallett M .
