However, research on outcomes after shunt surgery has mainly focused on the classical triad symptoms, that is, gait, cognition, and bladder dysfunction. This study aimed to describe the effects of shunt treatment on excessive daytime sleepiness and whether there was a relation to changes in ventricular volume. Pre\u2010 and postsurgical excessive daytime sleepiness was investigated using the Epworth sleepiness scale in a sample of 32 patients with normal pressure hydrocephalus who underwent shunt surgery. Data were gathered before surgery and at 1, 2, and 3\u2009months after surgery and with different settings of the shunt. In the total sample, the Epworth sleepiness scale improved by a median of 1.5 points at 1\u2009month after surgery, <jats:italic>p<\/jats:italic>\u2009=\u20090.026. The improvement was predominately found in the group (<jats:italic>n<\/jats:italic>\u2009=\u20096) with high presurgical daytime sleepiness (Epworth sleepiness scale &gt;12) (median\u2009=\u200912 points, <jats:italic>p<\/jats:italic>\u2009=\u20090.035) compared with a median change of 0 points (<jats:italic>p<\/jats:italic>\u2009=\u20090.47) in the group with Epworth sleepiness scale \u226412 (<jats:italic>n<\/jats:italic>\u2009=\u200926). Between the postsurgical follow\u2010ups, no further change in the Epworth sleepiness scale score was observed. The Epworth sleepiness scale score did not correlate with clinical tests nor with ventricular volume. Daytime sleepiness seems to be another domain of normal pressure hydrocephalus symptomatology in addition to the classical triad that is responsive to treatment, at least when pronounced. The Epworth sleepiness scale is a quick test to administer and could be a valuable addition to pre\u2010surgical screening for treatable symptoms.<\/jats:p>","DOI":"10.1111\/jsr.14333","type":"journal-article","created":{"date-parts":[[2024,9,14]],"date-time":"2024-09-14T09:44:56Z","timestamp":1726307096000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Decrease of excessive daytime sleepiness after shunt treatment for normal pressure hydrocephalus"],"prefix":"10.1111","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5137-2782","authenticated-orcid":false,"given":"Simon","family":"Lid\u00e9n","sequence":"first","affiliation":[{"name":"Department of Biomedical and Clinical Sciences, Neurology Link\u00f6ping University  Link\u00f6ping Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Lindam","sequence":"additional","affiliation":[{"name":"Department of Public Health and Clinical Medicine, Unit of Research, Education and Development \u2013 \u00d6stersund Ume\u00e5 University  Ume\u00e5 Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dan","family":"Farahmand","sequence":"additional","affiliation":[{"name":"Department of Clinical Neuroscience, Institute of Neuroscience and Physiology, Sahlgrenska Academy University of Gothenburg  Gothenburg Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anne\u2010Marie","family":"Landtblom","sequence":"additional","affiliation":[{"name":"Department of Biomedical and Clinical Sciences, Neurology Link\u00f6ping University  Link\u00f6ping Sweden"},{"name":"Department of Medical Sciences, Neurology Uppsala University  Uppsala Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katarina","family":"Laurell","sequence":"additional","affiliation":[{"name":"Department of Biomedical and Clinical Sciences, Neurology Link\u00f6ping University  Link\u00f6ping Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,9,14]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jns.2018.05.022"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/gps.4847"},{"key":"e_1_2_13_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.parkreldis.2020.11.009"},{"key":"e_1_2_13_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.sleep.2011.04.005"},{"key":"e_1_2_13_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/0271678X221090747"},{"key":"e_1_2_13_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00391-019-01670-9"},{"issue":"4","key":"e_1_2_13_8_1","first-page":"1","article-title":"Outcomes and complications of different surgical treatments for idiopathic normal pressure hydrocephalus: A systematic review and meta\u2010analysis","volume":"131","author":"Giordan E.","year":"2018","journal-title":"Journal of Neurosurgery"},{"key":"e_1_2_13_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/0022-510X(65)90016-X"},{"key":"e_1_2_13_10_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1592-13.2013"},{"key":"e_1_2_13_11_1","doi-asserted-by":"publisher","DOI":"10.1093\/neuros\/nyz297"},{"key":"e_1_2_13_12_1","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/14.6.540"},{"key":"e_1_2_13_13_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2869.2000.00177.x"},{"key":"e_1_2_13_14_1","doi-asserted-by":"publisher","DOI":"10.3389\/fneur.2022.843883"},{"key":"e_1_2_13_15_1","doi-asserted-by":"publisher","DOI":"10.1155\/2009\/791491"},{"key":"e_1_2_13_16_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0232275"},{"key":"e_1_2_13_17_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.65.4.497"},{"key":"e_1_2_13_18_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12987-022-00353-9"},{"key":"e_1_2_13_19_1","first-page":"1","article-title":"Volumetric effect of shunt adjustments in Normal pressure hydrocephalus: A randomized, double\u2010blind trial","volume":"17","author":"Liden S.","year":"2023","journal-title":"Journal of Neurosurgery"},{"issue":"1","key":"e_1_2_13_20_1","first-page":"38","article-title":"Apathy, ventriculomegaly and neurocognitive improvement following shunt surgery in Normal pressure hydrocephalus","volume":"30","author":"Peterson K.
