We aimed at developing an early risk score for CI based on clinical characteristics available at the onset of SAH. Out of a database containing 632 consecutive patients with SAH admitted to our institution from January 2005 to December 2012, computed tomography (CT) scans up to day 42 after ictus were evaluated for CIs. Different parameters from admission up to aneurysm treatment were collected with subsequent construction of a risk score. Seven clinical characteristics were independently associated with CI and included in the Risk score (BEHAVIOR Score, 0 to 11 points): Blood on CT scan according to Fisher grade \u2265 3 (1 point), Elderly patients (age \u2265 55 years, 1 point), Hunt&amp;Hess grade \u2265 4 (1 point), Acute hydrocephalus requiring external liquor drainage (1 point), Vasospasm on initial angiogram (3 points), Intracranial pressure elevation &gt; 20 mm Hg (3 points), and treatment of multiple aneurysms (\u2018Overtreatment\u2019, 1 point). The BEHAVIOR score showed high diagnostic accuracy with respect to the absolute risk for CI (area under curve = 0.806, P &lt; 0.0001) and prediction of poor clinical outcome at discharge ( P &lt; 0.0001) and after 6 months ( P = 0.0002). Further validation in other SAH cohorts is recommended.<\/jats:p>","DOI":"10.1038\/jcbfm.2015.81","type":"journal-article","created":{"date-parts":[[2015,4,29]],"date-time":"2015-04-29T04:04:34Z","timestamp":1430280274000},"page":"1587-1592","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":43,"title":["Early Identification of Individuals at High Risk for Cerebral Infarction after Aneurysmal Subarachnoid Hemorrhage: The BEHAVIOR Score"],"prefix":"10.1177","volume":"35","author":[{"given":"Ramazan","family":"Jabbarli","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University Medical Center Freiburg, Freiburg, Germany"},{"name":"Department of Neurosurgery, University Hospital Essen, Essen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthias","family":"Reinhard","sequence":"additional","affiliation":[{"name":"Department of Neurology, University Medical Center Freiburg, Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roland","family":"Roelz","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Medical Center Freiburg, Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mukesch","family":"Shah","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Medical Center Freiburg, Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wolf-Dirk","family":"Niesen","sequence":"additional","affiliation":[{"name":"Department of Neurology, University Medical Center Freiburg, Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Klaus","family":"Kaier","sequence":"additional","affiliation":[{"name":"Institute for Medical Biometry and Medical Informatics, University Medical Center Freiburg, Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Taschner","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, University Medical Center Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Astrid","family":"Weyerbrock","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Medical Center Freiburg, Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vera Van","family":"Velthoven","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Medical Center Freiburg, Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,4,29]]},"reference":[{"key":"bibr1-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.1007\/s12028-007-0003-2"},{"key":"bibr2-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.1007\/s00701-011-1243-7"},{"key":"bibr3-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000255396.23280.31"},{"key":"bibr4-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/aes264"},{"key":"bibr5-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.3171\/JNS.2008.109.12.1052"},{"key":"bibr6-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2005.102.2.0194"},{"key":"bibr7-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.0000133132.76983.8e"},{"key":"bibr8-jcbfm.2015.81","first-page":"1143","volume":"22","author":"Kivisaari RP","year":"2001","journal-title":"AJNR Am J Neuroradiol"},{"key":"bibr9-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.0000163090.59350.5a"},{"key":"bibr10-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.3171\/JNS-07\/12\/1074"},{"key":"bibr11-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.1007\/s00701-010-0715-5"},{"key":"bibr12-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.110.597005"},{"key":"bibr13-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.1227\/NEU.0b013e318285c3db"},{"key":"bibr14-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.1016\/j.jstrokecerebrovasdis.2013.01.006"},{"key":"bibr15-jcbfm.2015.81","doi-asserted-by":"publisher","DOI":"10.1007\/s00234-014-1406-3"},{"key":"bibr16-jcbfm.2015.81","unstructured":"Jabbarli R, Reinhard M, Niesen WD, Roelz R, Shah M, Kaier K,  Predictors and impact of early cerebral infarction after aneurysmal subarachnoid hemorrhage.
