A total of 70 consecutive patients, including 31 patients with visual hallucinations, and 39 patients without hallucinations, participated in this study. Patients with severe cognitive impairment (Mini\u2010Mental State Examination score &lt; 20), nonvisual hallucinations, or confusion were excluded. We compared brain perfusion changes between the two groups. We found that hallucinatory patients had significant perfusion reductions in the bilateral inferior parietal lobule, inferior temporal gyrus, precuneus gyrus, and occipital cortex compared to nonhallucinatory patients. These results suggested that hypoperfusion of the visual pathway was closely related to visual hallucinations in Parkinson's disease. \u00a9 2006 Movement Disorder Society<\/jats:p>","DOI":"10.1002\/mds.21140","type":"journal-article","created":{"date-parts":[[2006,10,6]],"date-time":"2006-10-06T16:48:30Z","timestamp":1160153310000},"page":"2140-2144","source":"Crossref","is-referenced-by-count":62,"title":["Hypoperfusion of the visual pathway in parkinsonian patients with visual hallucinations"],"prefix":"10.1002","volume":"21","author":[{"given":"Hideaki","family":"Matsui","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuto","family":"Nishinaka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaya","family":"Oda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Narihiro","family":"Hara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenichi","family":"Komatsu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tamotsu","family":"Kubori","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fukashi","family":"Udaka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,10,6]]},"reference":[{"issue":"6","key":"e_1_2_5_2_2","first-page":"S47","article-title":"Neuropsychological and psychiatric side effects in the treatment of Parkinson's disease","volume":"43","author":"Saint\u2010Cyr JA","year":"1993","journal-title":"Neurology"},{"key":"e_1_2_5_3_2","volume-title":"Parkinson's disease: cognitive and psychiatric aspects","author":"Yamamoto M","year":"2003"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1996.00550120077019"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.63.4.434"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/1531-8257(199901)14:1<117::AID-MDS1019>3.0.CO;2-0"},{"key":"e_1_2_5_7_2","first-page":"115","article-title":"Parkinson's disease: drug\u2010induced psychiatric states","volume":"65","author":"Factor SA","year":"1995","journal-title":"Adv Neurol"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1136\/pgmj.65.764.358"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/123.4.733"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.65.4.610"},{"key":"e_1_2_5_11_2","first-page":"327","volume-title":"Monoamines, Noyaux Gris Centraux et Syndrome de Parkinson","author":"de Ajuriaguerra J","year":"1971"},{"key":"e_1_2_5_12_2","first-page":"136","article-title":"Hallucinations in Parkinson's disease: a population study","volume":"14","author":"Tanner CM","year":"1983","journal-title":"Ann Neurol"},{"key":"e_1_2_5_13_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/121.10.1819"},{"key":"e_1_2_5_14_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00407835"},{"key":"e_1_2_5_15_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01271204"},{"key":"e_1_2_5_16_2","first-page":"289","article-title":"Poor visual discrimination and visual hallucinations in Parkinson's disease","volume":"21","author":"Diederich NJ","year":"1998","journal-title":"Clin Neuropharmacol"},{"key":"e_1_2_5_17_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.20308"},{"key":"e_1_2_5_18_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.wnf.0000157066.50948.65"},{"key":"e_1_2_5_19_2","first-page":"25","volume-title":"Human Brain Function","author":"Friston KJ","year":"1997"},{"key":"e_1_2_5_20_2","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000187116.13370.e0"},{"key":"e_1_2_5_21_2","first-page":"1238","article-title":"A diagnostic approach in Alzheimer's disease using three\u2010dimensional stereotactic surface projections of fluorine\u201018\u2010FDG PET","volume":"36","author":"Minoshima S","year":"1995","journal-title":"J Nucl Med"},{"key":"e_1_2_5_22_2","first-page":"2018","article-title":"Standardized Mini\u2010Mental State Examination.
