Pediatric patients with NF1, however, were more likely to have hypertension. Patients with NF1 were significantly more likely to be diagnosed with any stroke (odds ratio, 1.2;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.0001) than the general population. The odds of intracerebral hemorrhage were greatest among hemorrhagic stroke types analyzed (odds ratio, 1.9;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.0001). In the pediatric NF1 population, the odds of intracerebral hemorrhage were more dramatically elevated (odds ratio, 8.1;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.0001). The odds of ischemic stroke were also increased with NF1 in the pediatric (odds ratio, 3.4;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.0001) but not in the adult population.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>When compared with the general population, the odds of any type of stroke are significantly increased for patients with NF1, both adult and pediatric. This risk is most notable for hemorrhagic strokes although it is also increased for ischemic strokes in children. Physicians should be aware of the increased risk of stroke in this population, and consider stroke as a potential cause of new neurological symptoms.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/strokeaha.115.011406","type":"journal-article","created":{"date-parts":[[2015,12,9]],"date-time":"2015-12-09T18:16:11Z","timestamp":1449684971000},"page":"60-65","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":62,"title":["Increased Risk of Cerebrovascular Disease Among Patients With Neurofibromatosis Type 1"],"prefix":"10.1161","volume":"47","author":[{"given":"Anna R.","family":"Terry","sequence":"first","affiliation":[{"name":"From the Department of Neurosurgery, Duke University Medical Center\/Duke Raleigh Hospital, Raleigh, NC (A.R.T.); and Department of Neurology, Massachusetts General Hospital, Boston (J.T.J., L.S., S.R.P.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin T.","family":"Jordan","sequence":"additional","affiliation":[{"name":"From the Department of Neurosurgery, Duke University Medical Center\/Duke Raleigh Hospital, Raleigh, NC (A.R.T.); and Department of Neurology, Massachusetts General Hospital, Boston (J.T.J., L.S., S.R.P.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lee","family":"Schwamm","sequence":"additional","affiliation":[{"name":"From the Department of Neurosurgery, Duke University Medical Center\/Duke Raleigh Hospital, Raleigh, NC (A.R.T.); and Department of Neurology, Massachusetts General Hospital, Boston (J.T.J., L.S., S.R.P.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott R.","family":"Plotkin","sequence":"additional","affiliation":[{"name":"From the Department of Neurosurgery, Duke University Medical Center\/Duke Raleigh Hospital, Raleigh, NC (A.R.T.); and Department of Neurology, Massachusetts General Hospital, Boston (J.T.J., L.S., S.R.P.)."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.39.5.311"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ncl.2007.07.008"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.33139"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/ejhg.2011.113"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1093\/neuonc\/nos287"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2009-0152"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1097\/GIM.0b013e3181bf15e3"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1086\/320121"},{"key":"e_1_3_2_10_2","doi-asserted-by":"crossref","first-page":"136","DOI":"10.2340\/0001555575136140","article-title":"Life expectancy, mortality and prognostic factors in neurofibromatosis type 1.
