His mental health had deteriorated rapidly following the announcement of the results, with significant concerns about Brexit. He presented as agitated, confused and thought disordered. He had auditory hallucinations, and paranoid, referential, misidentification and bizarre delusions. He recovered completely within 2\u2009weeks after a brief admission and treatment with olanzapine. He had experienced a similar episode of much less severity 13\u2009years previously after major work related stress which resolved completely within a few days. He was experiencing stress related to work and family prior to the current episode which could potentially have been a contributory factor. Political events can act as major psychological stressors and have a significant impact on the mental health of people, especially those with a predisposition to develop mental illness.<\/jats:p>","DOI":"10.1136\/bcr-2019-232363","type":"journal-article","created":{"date-parts":[[2019,10,1]],"date-time":"2019-10-01T23:55:10Z","timestamp":1569974110000},"page":"e232363","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Acute transient psychotic disorder precipitated by Brexit vote"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1301-3359","authenticated-orcid":false,"given":"Mohammad Zia Ul Haq","family":"Katshu","sequence":"first","affiliation":[{"name":"Institute of Mental Health, University of Nottingham, Nottingham, UK"},{"name":"Nottinghamshire Healthcare NHS Foundation Trust, Nottingham, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,10,1]]},"reference":[{"key":"2025082722355866000_12.10.e232363.1","unstructured":"World Health Organization.
