The EEG signal, however, is often recorded from patients with epilepsy for a long period of time, and thus detection and identification of EDs have been a burden on medical doctors. This paper proposes a new method for automatic identification of two types of EDs, repeated sharp-waves (sharps), and runs of sharp-and-slow-waves (SSWs), which helps to pinpoint epileptogenic foci in secondary generalized epilepsy such as Lennox-Gastaut syndrome (LGS). In the experiments with iEEG data acquired from a patient with LGS, our proposed method detected EDs with an accuracy of 93.76% and classified three different signal patterns with a mean classification accuracy of 87.69%, which was significantly higher than that of a conventional wavelet-based method. Our study shows that it is possible to successfully detect and discriminate sharps and SSWs from background EEG activity using our proposed method.<\/jats:p>","DOI":"10.1155\/2016\/8701973","type":"journal-article","created":{"date-parts":[[2016,6,9]],"date-time":"2016-06-09T18:03:35Z","timestamp":1465495415000},"page":"1-10","source":"Crossref","is-referenced-by-count":4,"title":["Automatic Identification of Interictal Epileptiform Discharges in Secondary Generalized Epilepsy"],"prefix":"10.1155","volume":"2016","author":[{"given":"Won-Du","family":"Chang","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering, Hanyang University, Seoul 04763, Republic of Korea"}]},{"given":"Ho-Seung","family":"Cha","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Hanyang University, Seoul 04763, Republic of Korea"}]},{"given":"Chany","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Hanyang University, Seoul 04763, Republic of Korea"}]},{"given":"Hoon-Chul","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Severance Children\u2019s Hospital, Epilepsy Research Institute, Yonsei University College of Medicine, Seoul 03722, Republic of Korea"}]},{"given":"Chang-Hwan","family":"Im","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Hanyang University, Seoul 04763, Republic of Korea"}]}],"member":"98","reference":[{"key":"1","first-page":"21","volume-title":"A glossary of terms most commonly used by clinical electroencephalographers and proposal for the report form for the EEG findings","year":"1999"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.2005.069245"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/j.compbiomed.2011.05.007"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/TBME.2004.839630"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jneumeth.2012.07.015"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2009.06.057"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.18088\/ejbmr.1.4.2015.pp9-17"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/TBME.2008.2008858"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jneumeth.2010.09.017"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1016\/j.compbiomed.2009.01.004"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.jneumeth.2005.12.006"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(76)90063-8"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(85)91057-0"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2011.12.017"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.3367\/UFNe.0182.201209a.0905"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1140\/epjst\/e2013-02051-6"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1016\/j.jneumeth.2009.04.006"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-662-43850-3"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1007\/BF02648043"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1109\/tbme.2002.805477"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1038\/srep01483"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.4172\/2155-9562.S2-008"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-009-1015-3"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1007\/s002160000684"},{"key":"25","doi-asserted-by":"crossref","first-page":"576","DOI":"10.1016\/j.neucom.2015.06.071","volume":"171","year":"2016","journal-title":"Neurocomputing"}],"container-title":["Computational and Mathematical Methods in Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2016\/8701973.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2016\/8701973.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2016\/8701973.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,24]],"date-time":"2017-06-24T12:03:48Z","timestamp":1498305828000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cmmm\/2016\/8701973\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":25,"alternative-id":["8701973","8701973"],"URL":"https:\/\/doi.org\/10.1155\/2016\/8701973","relation":{},"ISSN":["1748-670X","1748-6718"],"issn-type":[{"value":"1748-670X","type":"print"},{"value":"1748-6718","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016]]}}}
