Beyond the lesion\u2010symptom maps, stroke is characterized by extensive structural and functional alterations of brain areas remote to local lesions. Here, we further investigated the structural changes over a global level by using DTI data of 10 ischemic stroke patients showing motor impairment due to basal ganglia lesions and 11 healthy controls. DTI data were processed to obtain fractional anisotropy (FA) maps, and multivariate pattern analysis was used to explore brain regions that play an important role in classification based on FA maps. The WM structural network was constructed by the deterministic fiber\u2010tracking approach. In comparison with the controls, the stroke patients showed FA reductions in the perilesional basal ganglia, brainstem, and bilateral frontal lobes. Using network\u2010based statistics, we found a significant reduction in the WM subnetwork in stroke patients. We identified the patterns of WM degeneration affecting brain areas remote to the lesions, revealing the abnormal organization of the structural network in stroke patients, which may be helpful in understanding of the neural mechanisms underlying hemiplegia.<\/jats:p>","DOI":"10.1002\/hbm.25583","type":"journal-article","created":{"date-parts":[[2021,7,7]],"date-time":"2021-07-07T14:44:56Z","timestamp":1625669096000},"page":"4750-4761","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["White matter degeneration in remote brain areas of stroke patients with motor impairment due to basal ganglia lesions"],"prefix":"10.1002","volume":"42","author":[{"given":"Xuejin","family":"Cao","sequence":"first","affiliation":[{"name":"Department of Neurology, Southeast University Zhongda Hospital Medical School of Southeast University  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zan","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Neurology, Southeast University Zhongda Hospital Medical School of Southeast University  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaohui","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Radiology, Zhongda Hospital, Jiangsu Key Laboratory of Molecular and Functional Imaging Medical School of Southeast University  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanli","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Southeast University Zhongda Hospital  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Radiology, Zhongda Hospital, Jiangsu Key Laboratory of Molecular and Functional Imaging Medical School of Southeast University  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Idriss Ali","family":"Abdoulaye","sequence":"additional","affiliation":[{"name":"Department of Neurology, Southeast University Zhongda Hospital Medical School of Southeast University  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5041-7865","authenticated-orcid":false,"given":"Shenghong","family":"Ju","sequence":"additional","affiliation":[{"name":"Department of Radiology, Zhongda Hospital, Jiangsu Key Laboratory of Molecular and Functional Imaging Medical School of Southeast University  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xi","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Southeast University Zhongda Hospital  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuancheng","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Radiology, Zhongda Hospital, Jiangsu Key Laboratory of Molecular and Functional Imaging Medical School of Southeast University  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6638-8963","authenticated-orcid":false,"given":"Yijing","family":"Guo","sequence":"additional","affiliation":[{"name":"Department of Neurology, Southeast University Zhongda Hospital Medical School of Southeast University  Nanjing China"},{"name":"Department of Neurology, Lishui People's Hospital Southeast University Zhongda Hospital Lishui Branch  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,7,7]]},"reference":[{"key":"e_1_2_11_2_1","first-page":"119","volume-title":"Progress in brain research","author":"Alexander G.
