Giant cell arteritis (GCA) is an autoimmune vasculitis affecting medium- and large-sized arteries. Vascular inflammation may lead to narrowing of the arterial lumen, and acute occlusion may result in vision loss and stroke. The classical symptoms include headache, fever, and jaw claudication. However, there is an increasing recognition of atypical presentations. Case Presentation. We report a case of a 70-year-old woman presenting with fluctuating manic symptoms and confusion, in addition to headache and musculoskeletal pain. After diagnosis of GCA, treatment with corticosteroids gradually improved the somatic symptoms. Conclusion. Corticosteroids led to a temporary exacerbation of manic symptoms, which improved after 3 to 4 weeks of continuous treatment, indicating that the symptoms were most likely associated with GCA. The patient manifested with clinical features and a clinical course that has, to our knowledge, not been described or published before. Therefore, GCA may be an underdiagnosed disease in psychiatric populations and should be considered in case of atypical, new-onset psychiatric disorders in the elderly.<\/jats:p>","DOI":"10.1155\/2023\/7989712","type":"journal-article","created":{"date-parts":[[2023,2,11]],"date-time":"2023-02-11T20:35:06Z","timestamp":1676147706000},"page":"1-5","source":"Crossref","is-referenced-by-count":1,"title":["Giant Cell Arteritis Presenting with Mania, Psychosis, and Cognitive Dysfunction: A Case Report"],"prefix":"10.1155","volume":"2023","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3404-2642","authenticated-orcid":true,"given":"Heidi Madeleine","family":"Latvala","sequence":"first","affiliation":[{"name":"Department of Addiction, Division of Mental Health and Addiction, University Hospital of Northern Norway, \u00c5sg\u00e5rdvegen 40, 9016 Troms\u00f8, Norway"},{"name":"Department of Internal Medicine, Finnmark Hospital Trust, Sykehusveien 35, 9601 Hammerfest, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3469-6822","authenticated-orcid":true,"given":"Solveig Kl\u00e6bo","family":"Reitan","sequence":"additional","affiliation":[{"name":"Department of Mental Health, St Olav University Hospital, Postboks 3250 Torgarden, 7006 Trondheim, Norway"},{"name":"Department of Mental Health, Faculty of Medicine and Health Science, Norwegian University of Science and Technology, H\u00f8gskoleringen 1, 7491 Trondheim, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4630-1517","authenticated-orcid":true,"given":"Arne Einar","family":"Vaaler","sequence":"additional","affiliation":[{"name":"Department of Mental Health, Faculty of Medicine and Health Science, Norwegian University of Science and Technology, H\u00f8gskoleringen 1, 7491 Trondheim, Norway"},{"name":"Department of Acute Psychiatry, St. Olav University Hospital, St. Olavs hospital HF, avd \u00d8stmarka, Postboks 3250 Torgarden, 7006 Trondheim, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9343(79)90744-7"},{"key":"2","doi-asserted-by":"crossref","first-page":"55","DOI":"10.1111\/j.1699-0463.1976.tb00110.x","article-title":"Immunological and histological studies of temporal arteries from patients with temporal arteritis and\/or polymyalgia rheumatica","volume":"84","author":"E.
