We report two patients with PD with symptoms that uniquely integrate visual hallucinations and delusions. We report two cases of patients with PD with visual hallucinations who saw the persistence of these hallucinations in photographs. These pictures were taken to prove the absence of these hallucinations. We believe this is the first description of this peculiar phenomenon, in which hallucinations or illusions could be replicated in photographs. Both patients had delusions associated with the images and we speculate that the images they saw in the photographs represent a further delusion, hence a \u2018delusional hallucination\u2019 or \u2018delusional illusion.\u2019 We believe that delusions fostering hallucinations are rare.<\/jats:p>","DOI":"10.1136\/bcr-2012-008372","type":"journal-article","created":{"date-parts":[[2013,5,23]],"date-time":"2013-05-23T08:55:26Z","timestamp":1369299326000},"page":"bcr2012008372","source":"Crossref","is-referenced-by-count":1,"title":["Visual hallucinations in photographs in Parkinson's disease"],"prefix":"10.1136","volume":"2013","author":[{"given":"Okeanis","family":"Vaou","sequence":"first","affiliation":[{"name":"Department of Neurology, Boston University Medical Center, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marie","family":"Saint-Hilaire","sequence":"additional","affiliation":[{"name":"Department of Neurology, Boston University Medical Center, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph","family":"Friedman","sequence":"additional","affiliation":[{"name":"Department of Neurology, Brown University, Providence, Rhode Island, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2013,5,22]]},"reference":[{"key":"2025082801485615000_2013.may22_1.bcr2012008372.1","doi-asserted-by":"crossref","first-page":"12","DOI":"10.1016\/j.jns.2009.08.014","article-title":"Epidemiology of psychosis in Parkinson's disease","volume":"2013","author":"Fenelon","year":"2010","journal-title":"J Neurol Sci"},{"key":"2025082801485615000_2013.may22_1.bcr2012008372.2","doi-asserted-by":"crossref","first-page":"1061","DOI":"10.1002\/mds.21382","article-title":"Diagnostic criteria for psychosis in Parkinson's disease: a report of an NINDS, NIMH work group","volume":"2013","author":"Ravina","year":"2007","journal-title":"Mov Disord"},{"key":"2025082801485615000_2013.may22_1.bcr2012008372.3","doi-asserted-by":"crossref","unstructured":"Stowe RL Ives NJ Clarke C .
