We report a case of a patient who presents with a common symptom, however, with a rare disease. This is an 84-year-old woman with a history of hypertension and atrial fibrillation who was reported to have confusion of 3\u2009weeks. Investigations, including a complete blood count, MRI imaging of the brain, cerebrospinal fluid analysis and paraneoplastic screen, were all negative. Of note, thyroid peroxidase antibody was elevated. She did not have a history of thyroid disease. Following this, an assessment of Hashimoto encephalopathy was made. She was started on steroids and she showed remarkable recovery within 2\u2009months, therefore, confirming the diagnosis. This case report emphasises the need to consider Hashimoto\u2019s encephalopathy as a differential for delirium especially when other common aetiologies have been ruled out.<\/jats:p>","DOI":"10.1136\/bcr-2019-230118","type":"journal-article","created":{"date-parts":[[2019,9,7]],"date-time":"2019-09-07T07:15:19Z","timestamp":1567840519000},"page":"e230118","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Hashimoto\u2019s encephalopathy: a rare cause of delirium"],"prefix":"10.1136","volume":"12","author":[{"given":"Osakpolor","family":"Ogbebor","sequence":"first","affiliation":[{"name":"Internal Medicine, Saint Peter\u2019s University Hospital, New Brunswick, New Jersey, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kavya","family":"Patel","sequence":"additional","affiliation":[{"name":"Internal Medicine, Saint Peter\u2019s University Hospital, New Brunswick, New Jersey, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,9,6]]},"reference":[{"key":"2025082801402674000_12.9.e230118.1","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.60.2.164"},{"key":"2025082801402674000_12.9.e230118.2","doi-asserted-by":"publisher","DOI":"10.2298\/VSP1105452D"},{"key":"2025082801402674000_12.9.e230118.3","first-page":"17","article-title":"A novel assessment and treatment approach to patients with Hashimoto\u2019s encephalopathy","volume":"2018","author":"Laycock","year":"2018","journal-title":"Endocrinol Diabetes Metab Case Rep"},{"key":"2025082801402674000_12.9.e230118.4","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.70.1.132"},{"key":"2025082801402674000_12.9.e230118.5","doi-asserted-by":"crossref","first-page":"309","DOI":"10.4103\/0976-3147.158753","article-title":"Hashimoto encephalopathy: A study of the clinical profile, radiological and electrophysiological correlation in a Tertiary Care Center in South India","volume":"6","author":"Sharma","year":"2015","journal-title":"J Neurosci Rural Pract"},{"key":"2025082801402674000_12.9.e230118.6","doi-asserted-by":"crossref","first-page":"42","DOI":"10.5765\/jkacap.180022","article-title":"Psychotic Symptoms of Hashimoto\u2019s Encephalopathy: A Diagnostic Challenge","volume":"30","author":"Savarimuthu","year":"2019","journal-title":"J Korean Acad Child Adolesc Psychiatry"},{"key":"2025082801402674000_12.9.e230118.7","doi-asserted-by":"crossref","first-page":"285","DOI":"10.1111\/ane.12618","article-title":"Hashimoto encephalopathy: literature review","volume":"135","author":"Zhou","year":"2017","journal-title":"Acta Neurol Scand"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2019-230118","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T08:40:32Z","timestamp":1756370432000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2019-230118"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,9]]},"references-count":7,"journal-issue":{"issue":"9","published-online":{"date-parts":[[2019,9,6]]},"published-print":{"date-parts":[[2019,9]]}},"alternative-id":["10.1136\/bcr-2019-230118"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2019-230118","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2019,9]]}}}
