To confirm these previous findings, we investigated the time course of sympathetic and cardiovascular activities during cataplexy. We made for the first time microneurographic recordings of 10 cataplectic episodes in three patients with hypocretin\u2010deficient narcolepsy. During microneurography, muscle sympathetic nerve activity (MSNA) was recorded simultaneously with heart rate (HR), respiratory movements, arterial finger blood pressure (BP), electroencephalography, electro\u2010oculogram and superficial electromyogram. Results showed no significant autonomic changes before the onset of the cataplectic episodes. Cataplexy was associated with a significant increase in MSNA and BP compared with baseline, whereas HR was markedly decreased. An irregular breathing pattern mainly characterized by apnea typically occurred during the attacks. In conclusion, our findings did not show significant changes in autonomic activity prior to cataplexy onset, ruling out a triggering role of the autonomic system. However, cataplexy was associated with co\u2010activation of sympathetic and parasympathetic autonomic systems, a pattern reminiscent of that reported during the vigilance reaction in animals.<\/jats:p>","DOI":"10.1111\/j.1365-2869.2008.00682.x","type":"journal-article","created":{"date-parts":[[2008,11,28]],"date-time":"2008-11-28T11:09:26Z","timestamp":1227870566000},"page":"458-463","source":"Crossref","is-referenced-by-count":27,"title":["Sympathetic and cardiovascular activity during cataplexy in narcolepsy"],"prefix":"10.1111","volume":"17","author":[{"given":"VINCENZO","family":"DONADIO","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"GIUSEPPE","family":"PLAZZI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"STEFANO","family":"VANDI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"CHRISTIAN","family":"FRANCESCHINI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"TOMAS","family":"KARLSSON","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"PASQUALE","family":"MONTAGNA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ROBERTO","family":"VETRUGNO","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ENRICO","family":"BUGIARDINI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"EMMANUEL","family":"MIGNOT","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ROCCO","family":"LIGUORI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2008,11,28]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"81","volume-title":"International Classification of Sleep Disorders","author":"American Academy of Sleep Medicine","year":"2005"},{"key":"e_1_2_9_3_1","volume-title":"The Autonomic Nervous System","author":"Appenzeller O.","year":"1982"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.smrv.2005.01.005"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awm037"},{"key":"e_1_2_9_6_1","author":"Duan Y.
