Cognitive function was investigated using the Wechsler Adult Intelligence Scale-III, Trail-Making Test, Wisconsin Card Sorting Test, Continuous Performance Test, Stroop test, and Wechsler Memory Scale. We assessed white matter integrity using diffusion tensor imaging, brain morphometry using magnetization-prepared rapid gradient-echo sequences, and brain connectivity using resting-state functional magnetic resonance imaging (MRI).<\/jats:p>\n <\/jats:sec>\n \n RESULTS<\/jats:title>\n \n Cognitive examinations revealed significant changes in the full-scale intelligence quotient (IQ), performance IQ (PIQ), perceptual organization (PO), processing speed, and Stroop test scores after surgery (\n P<\/jats:italic>\n \u00a0<\u00a0.05). Enlargement of the lateral ventricle, volume reductions in the corpus callosum and subcortical nuclei, and cortical thinning in the prefrontal cortex were also observed (\n P<\/jats:italic>\n \u00a0<\u00a0.05). Fractional anisotropy in the white matter tracts, including the superior longitudinal fasciculus, increased 2 to 4 yr after surgery, relative to that observed in the presurgical state (\n P<\/jats:italic>\n \u00a0<\u00a0.05). Resting-state brain connectivity was increased predominantly in the fronto-cerebellar circuit and was positively correlated with improvements in PIQ and PO (\n P<\/jats:italic>\n \u00a0<\u00a0.05).\n <\/jats:p>\n <\/jats:sec>\n \n CONCLUSION<\/jats:title>\n Revascularization surgery may improve processing speed and attention in adult patients with MMD. Further, multimodal MRI may be useful for detecting subtle postsurgical brain structural changes, reorganization of white matter tracts, and brain connectivity alterations.<\/jats:p>\n <\/jats:sec>","DOI":"10.1093\/neuros\/nyz176","type":"journal-article","created":{"date-parts":[[2019,4,17]],"date-time":"2019-04-17T08:23:58Z","timestamp":1555489438000},"page":"E943-E952","source":"Crossref","is-referenced-by-count":54,"title":["Brain Structure, Connectivity, and Cognitive Changes Following Revascularization Surgery in Adult Moyamoya Disease"],"prefix":"10.1227","volume":"85","author":[{"given":"Ken","family":"Kazumata","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Hokkaido University Graduate School of Medicine, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khin Khin","family":"Tha","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, Hokkaido University Hospital, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kikutaro","family":"Tokairin","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hokkaido University Graduate School of Medicine, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaki","family":"Ito","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hokkaido University Graduate School of Medicine, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haruto","family":"Uchino","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hokkaido University Graduate School of Medicine, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahito","family":"Kawabori","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hokkaido University Graduate School of Medicine, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taku","family":"Sugiyama","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hokkaido University Graduate School of Medicine, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2019,11]]},"reference":[{"issue":"11","key":"bib1-20231012","doi-asserted-by":"crossref","first-page":"1056","DOI":"10.1016\/S1474-4422(08)70240-0","article-title":"Moyamoya disease: Current concepts and future perspectives","volume":"7","author":"Kuroda","year":"2008","journal-title":"Lancet Neurol"},{"issue":"2","key":"bib2-20231012","doi-asserted-by":"crossref","first-page":"299","DOI":"10.3171\/2015.7.JNS142666","article-title":"Different aspects of dysexecutive syndrome in patients with moyamoya disease and its clinical subtypes","volume":"125","author":"Fang","year":"2016","journal-title":"J Neurosurg"},{"issue":"5","key":"bib3-20231012","doi-asserted-by":"crossref","first-page":"806","DOI":"10.1007\/s00415-009-5424-8","article-title":"Neurocognitive dysfunction in adult moyamoya disease","volume":"257","author":"Festa","year":"2010","journal-title":"J Neurol"},{"issue":"3","key":"bib4-20231012","doi-asserted-by":"crossref","first-page":"634","DOI":"10.1227\/NEU.0b013e3182320d1a","article-title":"Neurocognitive impairment in adults with moyamoya disease without stroke","volume":"70","author":"Karzmark","year":"2012","journal-title":"Neurosurgery"},{"issue":"5","key":"bib5-20231012","doi-asserted-by":"crossref","first-page":"1415","DOI":"10.1161\/STROKEAHA.113.004386","article-title":"Effects of extracranial-intracranial bypass for patients with hemorrhagic moyamoya disease: results of the Japan adult moyamoya trial","volume":"45","author":"Miyamoto","year":"2014","journal-title":"Stroke"},{"issue":"6","key":"bib6-20231012","doi-asserted-by":"crossref","first-page":"1514","DOI":"10.1161\/STROKEAHA.116.016028","article-title":"Neurocognitive performance after cerebral revascularization in adult moyamoya disease: results of the Japan adult moyamoya trial","volume":"48","author":"Zeifert","year":"2017","journal-title":"Stroke"},{"issue":"7-8","key":"bib7-20231012","doi-asserted-by":"crossref","first-page":"435","DOI":"10.1002\/nbm.782","article-title":"The basis of anisotropic water diffusion in the nervous system -
