After head\u2010down tilt, subcutaneous injections of either placebo or 6 mg of sumatriptan were administered. Chronic tension\u2010type headache intensity before and after withdrawal of 20 mL of cerebrospinal fluid was documented. Cerebrospinal pressure and chronic tension\u2010type headache intensity were measured after subcutaneous injection of 6 mg of sumatriptan.<\/jats:p>\n                  <jats:p>Results.\u2014Head\u2010down tilt provoked an increase of headache compared with baseline. Common carotid artery blood flow decreased and craniovascular resistance increased after sumatriptan injection, but not after placebo injection. The pain decreased after head\u2010down tilt and placebo injection, but not after sumatriptan injection. Chronic tension\u2010type headache intensity decreased in all 4 patients studied after withdrawal of 20 mL of cerebrospinal fluid. Cerebrospinal pressure increased in 5 patients with chronic tension\u2010type headache after subcutaneous injection of 6 mg of sumatriptan with slight or no increase of pain.<\/jats:p>\n                  <jats:p>Conclusion.\u2014The results indicated that cerebrospinal pressure or intracranial venous pressure (or both) are related to chronic tension\u2010type headache.<\/jats:p>","DOI":"10.1111\/j.1526-4610.2004.04032.x","type":"journal-article","created":{"date-parts":[[2004,7,26]],"date-time":"2004-07-26T12:23:00Z","timestamp":1090844580000},"page":"154-159","source":"Crossref","is-referenced-by-count":9,"title":["Relationship Between Chronic Tension\u2010type Headache, Cranial Hemodynamics, and Cerebrospinal Pressure: Study Involving Provocation With Sumatriptan"],"prefix":"10.1111","volume":"44","author":[{"given":"Jan","family":"Hannerz","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomas","family":"Jogestrand","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,2,3]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1526-4610.1998.3809668.x"},{"journal-title":"Headache","article-title":"Blood pool scintigraphy of the skull in relation to head down tilt provocation of chronic tension\u2010type headache patients and controls","author":"Hannerz J","key":"e_1_2_6_3_2"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0165-6147(91)90630-B"},{"key":"e_1_2_6_5_2","first-page":"165","article-title":"Sumatriptan is a potent vasoconstrictor of human dural arteries via 5HT1\u2010like receptor","volume":"11","author":"Jansen I","year":"1991","journal-title":"Cephalalgia"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5381.1989.tb11835.x"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-2982.1992.00375.x"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-1331.1996.tb00184.x"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399-6576.1996.tb04497.x"},{"issue":"7","key":"e_1_2_6_10_2","first-page":"1","article-title":"Headache Classification Committee of the International Headache Society.
