Like patients with Parkinson\u2019s disease (PD), patients with progressive supranuclear palsy (PSP) tend to produce fewer correct words than age-matched healthy adults. This study further examined the difference between patients with PSP and PD in their semantic fluency performance using a graph theory-based approach. Twenty-nine patients with PSP Richardson\u2019s syndrome (PSP-RS), thirty-eight patients with PD, and fifty-one healthy controls (HC) were recruited. All participants completed a standard semantic fluency test (animals). Their verbal responses were recorded, transcripted, and transformed into directed speech graphs. The speech graphs of the PSP-RS group showed higher density, shorter diameter, and shorter average shortest path than those of the PD and HC groups. It indicates that the PSP-RS group produced smaller and denser speech graphs than the PD and HC groups. In the PSP-RS group, moreover, the average shortest paths of the speech graphs correlated with the severity of motor symptoms. This study shows the potential of the graph theory-based approach in distinguishing the semantic fluency performance of nondemented patients with PSP-RS and PD.<\/jats:p>","DOI":"10.1155\/2023\/3771601","type":"journal-article","created":{"date-parts":[[2023,9,25]],"date-time":"2023-09-25T18:05:07Z","timestamp":1695665107000},"page":"1-7","source":"Crossref","is-referenced-by-count":3,"title":["Smaller and Denser Speech Graphs in Nondemented Patients with Progressive Supranuclear Palsy"],"prefix":"10.1155","volume":"2023","author":[{"given":"Jinghong","family":"Ma","sequence":"first","affiliation":[{"name":"Department of Neurology, Xuanwu Hospital of Capital Medical University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0965-218X","authenticated-orcid":true,"given":"Guanyu","family":"Zhang","sequence":"additional","affiliation":[{"name":"China Institute of Sport Science, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaomin","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Neurology, Weifang People\u2019s Hospital, Weifang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piu","family":"Chan","sequence":"additional","affiliation":[{"name":"Department of Neurobiology, Neurology and Geriatrics, Xuanwu Hospital of Capital Medical University, Beijing Institute of Geriatrics, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1912-6992","authenticated-orcid":true,"given":"Zheng","family":"Ye","sequence":"additional","affiliation":[{"name":"Institute of Neuroscience, Center for Excellence in Brain Science and Intelligence Technology, Chinese Academy of Sciences, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.57.11.1389"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1007\/s11682-022-00698-7"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0000000000002638"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1002\/mds.27619"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1046\/j.1468-1331.9.s3.3.x"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1037\/0894-4105.11.1.138"},{"key":"7","doi-asserted-by":"crossref","DOI":"10.1212\/WNL.90.15_supplement.P6.082","article-title":"The phonemic verbal fluency in progressive supranuclear palsy (PSP) and Parkinson\u2019s disease (PD): relation with executive and language function measure","volume":"90","author":"S.
