Absences began 1 to 9 (4.5 \u00b1 2.5) years before myoclonic jerks and generalized tonic\u2010clonic seizures. Clinical manifestations during the absence ictus showed great variation, ranging from subtle or no overt features to severe impairment of consciousness, and severity was age related. Simple and complex absence seizures can occur in the same patient. The electroencephalographic features were distinct, with many interictal discharges, fragmentation of the paroxysms, and frequent polyspikes of varying numbers and amplitude for each spike\u2010slow wave component. The combined clinical\u2010electroencephalographic manifestations were characteristic and allow differentiation of absences in juvenile myoclonic epilepsy from typical absence seizures in other epileptic syndromes.<\/jats:p>","DOI":"10.1002\/ana.410250411","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T14:09:58Z","timestamp":1104588598000},"page":"391-397","source":"Crossref","is-referenced-by-count":69,"title":["Absences in juvenile myoclonic epilepsy: A clinical and video\u2010electroencephalographic study"],"prefix":"10.1002","volume":"25","author":[{"given":"Chrysostomos P.","family":"Panayiotopoulos","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tahir","family":"Obeid","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ghazala","family":"Waheed","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,10,8]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00242439"},{"key":"e_1_2_1_3_2","volume-title":"Die Epilepsien","author":"Janz D","year":"1969"},{"key":"e_1_2_1_4_2","first-page":"55","volume-title":"Evolution and prognosis of epilepsies","author":"Janz D","year":"1972"},{"key":"e_1_2_1_5_2","first-page":"339","article-title":"Epilepsy with impulsive petit mal (juvenile myoclonic epilepsy)","volume":"72","author":"Janz D","year":"1985","journal-title":"Acta Neurol Scand"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1528-1157.1985.tb05417.x"},{"key":"e_1_2_1_7_2","doi-asserted-by":"crossref","first-page":"285","DOI":"10.1212\/WNL.34.3.285","article-title":"Enrile\u2010Bascal FE.
