We aimed to evaluate the diagnostic stability of brief psychoses with late-life onset.MethodsA 10-year retrospective analysis of all records of elderly patients with a first-ever episode of psychosis was undertaken.ResultsOf 2,072 admissions of elderly patients, 604 had their first brief psychotic disorder (International Classification of Diseases diagnoses). All \u201corganic\u201d psychoses were excluded. The study sample comprised 83 individuals (36 male, 47 female) with a mean \u00b1 SD age of 75.4\u00b19.3 years (range: 65\u201392). Mean follow-up duration was 27.7 months (range: 6\u2013120). Distribution of diagnoses was as follows: unspecified nonorganic psychosis (n = 71); persistent delusional disorder (n = 10); other nonorganic psychosis (n = 1); and acute and transient psychotic disorder (n = 1). At follow-up, diagnosis of very late-onset schizophrenia-like psychosis and switch to another brief psychotic disorder were the most frequent outcomes.ConclusionsThe diagnosis of a nonorganic psychosis first manifesting in the elderly is not rare in tertiary care. Diagnostic shift at follow-up of these patients is more common than conceptualized, requiring flexibility on the part of treating physicians.<\/jats:p>","DOI":"10.5770\/cgj.v14i2.9","type":"journal-article","created":{"date-parts":[[2011,10,5]],"date-time":"2011-10-05T00:40:46Z","timestamp":1317775246000},"page":"30-33","source":"Crossref","is-referenced-by-count":5,"title":["First Onset Functional Brief Psychoses in the Elderly"],"prefix":"10.5770","volume":"14","author":[{"given":"Yoram","family":"Barak","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Levy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henry","family":"Szor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dov","family":"Aizenberg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3968","published-online":{"date-parts":[[2011,5,31]]},"container-title":["Canadian Geriatrics Journal"],"original-title":[],"link":[{"URL":"https:\/\/cgjonline.ca\/index.php\/cgj\/article\/download\/9\/34","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/cgjonline.ca\/index.php\/cgj\/article\/download\/9\/36","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/cgjonline.ca\/index.php\/cgj\/article\/download\/9\/34","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,9,8]],"date-time":"2021-09-08T21:58:34Z","timestamp":1631138314000},"score":1,"resource":{"primary":{"URL":"https:\/\/cgjonline.ca\/index.php\/cgj\/article\/view\/9"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,5,31]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2011,7,7]]}},"URL":"https:\/\/doi.org\/10.5770\/cgj.v14i2.9","relation":{},"ISSN":["1925-8348"],"issn-type":[{"value":"1925-8348","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,5,31]]}}}
