Objective: To investigate the implication of SVD MRI markers in cognitively impaired patients with AD and\/or LBD. Methods: We consecutively recruited 57 patients with pure AD-related cognitive impairment (ADCI), 49 with pure LBD-related cognitive impairment (LBCI), 45 with mixed ADCI\/LBCI, and 34 controls. All participants underwent neuropsychological tests, brain MRI, and amyloid positron emission tomography. SVD MRI markers including the severity of deep and PWMH and the number of lacunes and microbleeds were visually rated. The relationships among vascular risk factors, SVD MRI markers, ADCI, LBCI, and cognitive scores were investigated after controlling for appropriate covariates. Results: LBCI was associated with more severe PWMH, which was conversely associated with an increased risk of LBCI independently of vascular risk factors and ADCI. PWMH was associated with attention and visuospatial dysfunction independently of vascular risk factors, ADCI, and LBCI. Both ADCI and LBCI were associated with more lobar microbleeds, but not with deep microbleeds. Conclusion: Our findings suggest that PWMH could reflect degenerative process related with LBD, and both AD and LBD independently increase lobar microbleeds.<\/jats:p>","DOI":"10.3233\/jad-210669","type":"journal-article","created":{"date-parts":[[2021,8,6]],"date-time":"2021-08-06T13:00:44Z","timestamp":1628254844000},"page":"545-556","source":"Crossref","is-referenced-by-count":6,"title":["Implication of Small Vessel Disease MRI Markers in Alzheimer\u2019s Disease and Lewy Body Disease1"],"prefix":"10.1177","volume":"83","author":[{"given":"Mincheol","family":"Park","sequence":"first","affiliation":[{"name":"Department of Neurology, Yonsei University College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyoungwon","family":"Baik","sequence":"additional","affiliation":[{"name":"Department of Neurology, Yonsei University College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young-gun","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Neurology, Yonsei University College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sung Woo","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Neurology, Yonsei University College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin Ho","family":"Jung","sequence":"additional","affiliation":[{"name":"Department of Neurology, Yonsei University College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seong Ho","family":"Jeong","sequence":"additional","affiliation":[{"name":"Department of Neurology, Yonsei University College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Phil Hyu","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Neurology, Yonsei University College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young H.","family":"Sohn","sequence":"additional","affiliation":[{"name":"Department of Neurology, Yonsei University College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Byoung Seok","family":"Ye","sequence":"additional","affiliation":[{"name":"Department of Neurology, Yonsei University College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"key":"10.3233\/JAD-210669_ref1","doi-asserted-by":"crossref","first-page":"415","DOI":"10.1007\/s00401-003-0676-3","article-title":"Prevalence of cerebrovascular lesions in Parkinson\u2019s disease.
