The clinical features of language disorder and predominant atrophy on MRI and predominant hypoperfusion on\n 123<\/jats:sup>\n I-IMP SPECT in the left temporo-parietal junction area were consistent with the diagnostic criteria for the logopenic variant of primary progressive aphasia (lvPPA). Neurological examination showed slight right-side rigidity and resting tremor (UPDRS-III: 4).\n 123<\/jats:sup>\n I-FP-CIT SPECT showed presynaptic dopamine transporter reduction in the posterior putamina with left-side predominance. The odor-stick identification test for Japanese exhibited complete loss of the sense of smell (anosmia). These findings suggest that lvPPA may be accompanied by parkinsonism and anosmia.\n <\/jats:p>","DOI":"10.3233\/adr-190158","type":"journal-article","created":{"date-parts":[[2020,3,6]],"date-time":"2020-03-06T10:12:06Z","timestamp":1583489526000},"page":"61-66","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["A Case of Logopenic Variant of Primary Progressive Aphasia with Parkinsonism and Anosmia"],"prefix":"10.1177","volume":"4","author":[{"given":"Shoichi","family":"Sasaki","sequence":"first","affiliation":[{"name":"Department of Neurology, Agano City Hospital, Niigata, Japan"},{"name":"Department of Neurology, Toyosaka Hospital, Niigata, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,3,4]]},"reference":[{"key":"ref001","doi-asserted-by":"publisher","DOI":"10.1002\/ana.10825"},{"key":"ref002","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0b013e31821103e6"},{"key":"ref003","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A2935"},{"key":"ref004","doi-asserted-by":"publisher","DOI":"10.1002\/ana.91"},{"key":"ref005","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awt266"},{"key":"ref006","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000244749.20056.d4"},{"key":"ref007","doi-asserted-by":"publisher","DOI":"10.1002\/ana.21451"},{"key":"ref008","doi-asserted-by":"publisher","DOI":"10.1177\/1533317510391239"},{"key":"ref009","doi-asserted-by":"publisher","DOI":"10.1016\/j.parkreldis.2012.04.011"},{"key":"ref010","doi-asserted-by":"publisher","DOI":"10.1111\/ene.12196"},{"key":"ref011","doi-asserted-by":"publisher","DOI":"10.1515\/tnsci-2018-0001"},{"key":"ref012","doi-asserted-by":"publisher","DOI":"10.1016\/bs.irn.2017.05.028"},{"key":"ref013","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.2003.032003"},{"key":"ref014","first-page":"3","volume-title":"Clinical Neurology of Aging","author":"Kemper T","year":"1984"},{"key":"ref015","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A2350"},{"key":"ref016","doi-asserted-by":"publisher","DOI":"10.1093\/chemse\/bjq028"},{"key":"ref017","first-page":"2","volume":"9","author":"Sasaki S","year":"2019","journal-title":"J Alzheimers Dis Parkinsonism"},{"key":"ref018","doi-asserted-by":"publisher","DOI":"10.3233\/JAD-2009-1036"},{"key":"ref019","doi-asserted-by":"publisher","DOI":"10.1159\/000346289"},{"key":"ref020","doi-asserted-by":"publisher","DOI":"10.1002\/ana.21388"},{"key":"ref021","doi-asserted-by":"publisher","DOI":"10.1002\/ana.25333"},{"key":"ref022","doi-asserted-by":"publisher","DOI":"10.1001\/jamaneurol.2017.4309"},{"key":"ref023","doi-asserted-by":"publisher","DOI":"10.1001\/jamaneurol.2015.2952"},{"key":"ref024","doi-asserted-by":"publisher","DOI":"10.1016\/0361-9230(87)90129-8"},{"key":"ref025","doi-asserted-by":"publisher","DOI":"10.1002\/ana.20533"},{"key":"ref026","doi-asserted-by":"publisher","DOI":"10.1097\/YCO.0000000000000146"},{"key":"ref027","doi-asserted-by":"publisher","DOI":"10.1038\/nrneurol.2012.80"},{"key":"ref028","doi-asserted-by":"publisher","DOI":"10.1002\/ana.21291"},{"key":"ref029","doi-asserted-by":"publisher","DOI":"10.1007\/s00702-002-0808-2"},{"key":"ref030","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awx208"},{"key":"ref031","doi-asserted-by":"publisher","DOI":"10.1093\/chemse\/bjq139"}],"container-title":["Journal of Alzheimer's Disease Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/ADR-190158","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.3233\/ADR-190158","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/ADR-190158","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T09:56:44Z","timestamp":1777370204000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/ADR-190158"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,3,4]]},"references-count":31,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2020,12,28]]}},"alternative-id":["10.3233\/ADR-190158"],"URL":"https:\/\/doi.org\/10.3233\/adr-190158","relation":{},"ISSN":["2542-4823","2542-4823"],"issn-type":[{"value":"2542-4823","type":"print"},{"value":"2542-4823","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,3,4]]}}}
