Of the nondemented hallucinating PD patients nearly 70% showed impairment in multiple cognitive domains. The progressive decline in hallucinating PD patients affected mainly visual memory for faces and visuoperceptive-visuospatial functions. &lt;i&gt;Conclusion:&lt;\/i&gt; Our results support a fast impairment of complex visual functions in hallucinating PD patients, but also a progressive decline in multiple cognitive domains, which have been identified as a risk of developing dementia in PD.<\/jats:p>","DOI":"10.1159\/000100850","type":"journal-article","created":{"date-parts":[[2007,3,12]],"date-time":"2007-03-12T12:22:03Z","timestamp":1173702123000},"page":"281-288","source":"Crossref","is-referenced-by-count":90,"title":["Cognitive Changes in Parkinson\u2019s Disease Patients with Visual Hallucinations"],"prefix":"10.1159","volume":"23","author":[{"given":"Blanca","family":"Ramirez-Ruiz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carme","family":"Junque","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria-Jose","family":"Marti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesc","family":"Valldeoriola","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduardo","family":"Tolosa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2007,3,14]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016%2FS1474-4422%2805%2970146-0"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1002%2Fgps.1339"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1002%2Fmds.20719"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016%2FS0028-3932%2802%2900182-3"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1001%2Farchneur.60.3.387"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1001%2Farchneur.61.12.1906"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1600-0447.1994.tb01508.x"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1136%2Fjnnp.23.1.56"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1212%2FWNL.44.12.2308"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1001%2Farchneur.56.3.303"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016%2F0022-3956%2875%2990026-6"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1007%2Fs11910-003-0053-6"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1093%2Fbrain%2Fawf033"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1212%2F01.wnl.0000187116.13370.e0"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1002%2Fhbm.10076"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.visres.2004.11.006"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1002%2Fmds.20308"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1002%2Fmds.20129"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.parkreldis.2005.10.005"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00702-004-0168-1"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00415-005-0918-5"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1212%2F01.WNL.0000158422.41380.82"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1002%2Fmds.20216"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1002%2Fmds.10280"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1177%2F0891988705277540"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1002%2Fmds.20652"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1136%2Fjnnp.2004.058685"},{"key":"ref28","doi-asserted-by":"publisher","DOI":"10.1017%2FS1355617703910022"}],"container-title":["Dementia and Geriatric Cognitive Disorders"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/100850","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/100850","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T02:55:02Z","timestamp":1745463302000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000100850"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007]]},"references-count":28,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2007,4,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000100850","archive":["Portico"],"relation":{},"ISSN":["1420-8008","1421-9824"],"issn-type":[{"value":"1420-8008","type":"print"},{"value":"1421-9824","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007]]}}}
