The aim of this study was to evaluate the utility of MRI-based DESH scoring for predicting prognosis after surgery.<\/jats:p>\n <\/jats:sec>\n \n METHODS<\/jats:title>\n In this single-center, retrospective cohort study, the DESH score was determined by consensus between a group of neurosurgeons, neurologists, and a neuroradiologist based on the preoperative MRI findings of the patients with suspected iNPH. The DESH score was composed of the following 5 items, each scored from 0 to 2 (maximum score 10 points): ventriculomegaly, dilated sylvian fissures, tight high convexity, acute callosal angle, and focal sulcal dilation. The association between the DESH score and improvement of the scores on the modified Rankin Scale (mRS), iNPH Grading Scale (iNPHGS), Mini\u2013Mental State Examination (MMSE), Trail Making Test-A (TMT-A), and Timed 3-Meter Up and Go Test (TUG-t) was examined. The primary end point was improvement in the mRS score at 1 year after surgery, and the secondary outcome measures were the iNPHGS, MMSE, TMT-A, and TUG-t scores at 1 year after surgery. Improvement was determined as improvement of 1 or more levels on mRS, \u2265 1 point on iNPHGS, \u2265 3 points on MMSE, a decrease of > 30% on TMT-A, and a decrease of > 10% on TUG-t.<\/jats:p>\n <\/jats:sec>\n \n RESULTS<\/jats:title>\n The mean DESH score for the 50 patients (mean age 77.6 \u00b1 5.9 years) reviewed in this study was 5.58 \u00b1 2.01. The mean rate of change in the mRS score was \u22120.50 \u00b1 0.93, indicating an inverse correlation between the DESH score and rate of change in the mRS score (r = \u22120.749). Patients who showed no improvement in mRS score tended to have a low DESH score as well as low preoperative MMSE and TMT-A scores. There were no differences in the areas of deep white matter hyperintensity and periventricular hyperintensity on the images between patients with and without an improved mRS score (15.6% vs 16.7%, respectively; p = 1.000). The DESH score did differ significantly between patients with and without improved scores on the iNPHGS (6.39 \u00b1 1.76 vs 4.26 \u00b1 1.69, respectively; p < 0.001), MMSE (6.63 \u00b1 1.82 vs 5.09 \u00b1 1.93; p = 0.010), TMT-A (6.32 \u00b1 1.97 seconds vs 5.13 \u00b1 1.93 seconds; p = 0.042), and TUG-t (6.48 \u00b1 1.81 seconds vs 4.33 \u00b1 1.59 seconds; p < 0.001).<\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS<\/jats:title>\n MRI-based DESH scoring is useful for the prediction of neurological improvement and prognosis after surgery for iNPH.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/2016.9.jns161080","type":"journal-article","created":{"date-parts":[[2017,2,3]],"date-time":"2017-02-03T09:59:41Z","timestamp":1486115981000},"page":"1436-1442","source":"Crossref","is-referenced-by-count":105,"title":["Utility of MRI-based disproportionately enlarged subarachnoid space hydrocephalus scoring for predicting prognosis after surgery for idiopathic normal pressure hydrocephalus: clinical research"],"prefix":"10.3171","volume":"127","author":[{"given":"Narihide","family":"Shinoda","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Shinko Hospital, Kobe, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Osamu","family":"Hirai","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shinko Hospital, Kobe, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinya","family":"Hori","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shinko Hospital, Kobe, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuyuki","family":"Mikami","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shinko Hospital, Kobe, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiaki","family":"Bando","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shinko Hospital, Kobe, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daisuke","family":"Shimo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shinko Hospital, Kobe, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takahiro","family":"Kuroyama","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shinko Hospital, Kobe, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoji","family":"Kuramoto","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shinko Hospital, Kobe, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masato","family":"Matsumoto","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shinko Hospital, Kobe, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasushi","family":"Ueno","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shinko Hospital, Kobe, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-jns161080","series-title":"Radiat Med","doi-asserted-by":"publisher","first-page":"568","DOI":"10.1007\/s11604-006-0074-6","article-title":"Upper midbrain profile sign and cingulate sulcus sign: MRI findings on sagittal images in idiopathic normal-pressure hydrocephalus, Alzheimer's disease, and progressive supranuclear palsy","volume":"24","author":"Adachi M,","year":"2006","unstructured":"Adachi M, Kawanami T, Ohshima F, Kato T: Upper midbrain profile sign and cingulate sulcus sign: MRI findings on sagittal images in idiopathic normal-pressure hydrocephalus, Alzheimer's disease, and progressive supranuclear palsy.
