Epilepsy is the most common paroxysmal disorders seen in the childhood. But other nonepileptic paroxysmal events are confused with epileptic seizures or have unusual clinical features. Nonepileptic paroxysmal disorders tend to recur episodically. So differential diagnosis between epileptic and nonepileptic disorders in fundamental not only to allow correct management of patients and but also avoid of unnecessary antiepileptic medications. To accurate diagnosis of nonepileptic paroxysmal disorders, the patients' age and accurate description of the events are need.

기질적 뇌병변에 의한 부분 간질환자에서 수면이 간질파의 발생에 미치는 영향을 밝히기 위하여 본 연구를 시행하였다. 기질적 뇌병변에 의한 부분 간질환자 16명과 뇌병변이 없는 34명을 대상으로 50% 수면박탈 후에 통상적인 각성뇌파와 수면뇌파를 동시에 기록하였다. 각성 간질파 지수, 수면 간질파 지수 및 수면에 의한 간질파 지수의 증가율을 구한 후에 기질적 병변의 유무, 발작 및 간질의 종류, 야간 수면 발작의 유무, 이차적 전신성 발작의 유무, 항경련제의 복용 여부, 환자의 나이 및 간질의 발병 연령과 유병 기간에 따른 유의한 차이가 있는지 분석하였다. 1. NREM 수면 기간에 간질파의 발생이 유의하게 증가하였으나 기질적인 뇌병변의 유무에 따른 차이는 없었다(p<0.05). 2. 수면 기간 중 간질파의 증가는 이차적 전신발작의 빈도, 간질 및 발작의 종류, 야간 수면 발작의 빈도, 항경련제 복용에 따른 유의한 차이가 없었다. 3. 전체 50명 가운데 13명(26%) 에서는 수면 상태에서만 간질파가 관찰되었고, 1명(2%) 에서는 각성 상태에서만 간질파가 관찰되었다. 4. 대상 환자 50명 가운데 44명(88%)에서 수면 간질파 지수가 높았고, 5명(10%)에서는 각성 간질파 지수가 높았다(p<0.01). 이상의 결과로 볼 때 기질적 뇌병변을 가진 부분 간질환자에서 통상적인 외래 뇌파검사의 진단율을 높이고 간질파를 활성화시키기 위해서는 수면박탈 후에 각성 상태뿐만 아니라 NREM 수면 상태의 뇌파를 기록하여야 할 것이다.

Since epileptic seizure is unpredictable and paroxysmal, an automatic system for seizure detecting could be of great significance and assistance to patients and medical staff. In this paper, a novel method is proposed for multichannel patient-specific seizure detection applying the earth mover's distance (EMD) in scalp EEG. Firstly, the wavelet decomposition is executed to the original EEGs with five scales, the scale 3, 4 and 5 are selected and transformed into histograms and afterwards the distances between histograms in pairs are computed applying the earth mover's distance as effective features. Then, the EMD features are sent to the classifier based on the Bayesian linear discriminant analysis (BLDA) for classification, and an efficient postprocessing procedure is applied to improve the detection system precision, finally. To evaluate the performance of the proposed method, the CHB-MIT scalp EEG database with 958 h EEG recordings from 23 epileptic patients is used and a relatively satisfactory detection rate is achieved with the average sensitivity of 95.65% and false detection rate of 0.68/h. The good performance of this algorithm indicates the potential application for seizure monitoring in clinical practice.

Glioblastoma (GBM) is the most common and aggressive type of primary brain neoplasm. The current standard therapy for GBM consists of maximal surgical resection within safe limits, followed by radiation therapy (RT) and chemotherapy with temozolomide. Despite advances in treatment, the prognosis of GBM remains poor. Epileptic seizure is one of the most common symptoms in patients with GBM. Valproic acid (VPA), a histone deacetylase inhibitor, is often used as an anti-epileptic drug in patients with brain neoplasms due to its effectiveness and low toxicity profile. Several in vivo and in vitro studies have indicated that VPA has radiosensitizing effects for gliomas and radioprotective influence on normal brain tissue or hippocampal neurons. The results of several retrospective studies have also indicated potential benefit to improve survival of patients with GBM. Moreover, the promising treatment results of a phase 2 trial of concurrent radiation therapy, temozolomide, and VPA for patients with GBM have been recently reported. The use of VPA in patients with GBM has thus recently receiving more attention. In this article, we review the role of VPA in radiation therapy for GBM, focusing on the clinical evidence.

Lamotrigine is a newer anti-epileptic drug for adjunctive treatment of refractory epilepsy, partial seizures, generalized tonic-clonic seizures, and bipolar disorder. Lamotrigine overdose causes serious central nervous and cardiovascular problems, but reports are uncommon. Few lamotrigine overdoses have been described because anti-epileptic drug use is limited and usually used with combination of other anti-epileptic drugs. In addition, most patients visit emergency departments with multi-drug overdoses, so few cases of lamotrigine poisoning alone exist. We had a female patient visit our emergency department a couple of hours after a lamotrigine overdose treated with intravenous hydration and urine alkalization by NaHCO3. She recovered successfully without any evidence of renal injury. However, she developed profound rhabdomyolysis, a previously unreported complication of this medication. We suggest that serial creatine kinase levels should be measured after lamotrigine poisoning.

Epilepsy is one of the most prevalent neurological diseases. Electroencephalogram (EEG) signals are widely used for monitoring and diagnosis tool for epileptic seizure. Typically, a huge amount of EEG signals is needed, where they are visually examined by experienced clinicians. In this study, we propose a simple automatic seizure detection framework using intracranial EEG signals. We suggest a sparse approximation based classification (SAC) scheme by solving overdetermined system. L1-norm minimization algorithms are utilized for efficient sparse signal recovery. For evaluation of the proposed scheme, the public EEG dataset obtained by five healthy subjects and five epileptic patients is utilized. The results show that the proposed fast L1-norm minimization based SAC methods achieve the 99.5% classification accuracy which is 1% improved result than the conventional L2 norm based method with negligibly increased execution time (42msec).

Psychogenic Non Epileptic Seizure (PNES) refers to a case in which symptoms are similar to epileptic seizures (ES), but ES do not appear in EEG and temporary abnormalities caused by physical diseases are also excluded. Psychotherapy and pharmacotherapy are most commonly used, but standard treatment for PNES has not been established and there is no alternative treatment available in the case of patients those treatments are not applied. We herein report a case of 46 year old male diagnosed with PNES who suffered from generalized tonic-clonic seizures. The patient underwent korean medical treatment by acupuncture and herbal medicine. The clinical symptom was evaluated by assessing occurrence frequency, number of seizures per 28 days. Compared to the period without korean medical treatment, the number of seizures decreased during the treatment period. The present case report suggested that korean medical treatment could be an effective option for those PNES patients complaining generalized tonic-clonic seizures.

Two interview surveys (1976 for 800 patients, 1978 for 200 patients) and an inventory survey through medical records(1978) for epileptic patients who have registered with the Korean Epilepsy Association (Rose Club) since 1971 were carried out by trained health workers in advance of survey. The data obtained from the analysis showed as follows: 1) 35.2% of patients were born in Seoul and 70. 6% of patients born elsewhere have lived in Seoul. 2) 50-60% of patients were 15-30 years cid. 3) 33.4%, 24,6 and 24.6 of all pupils and students went to elementary, junior and senior high schools respectively. 4) 21.2% of all pupils and students had dropped out of school and 51.4% of them were away from school because of epilepsy. 5) 3.1% of all patients had no job at all and students comprised 20.9% of patients followed by clerical work, commercial business and farming with about 6% in each group.6) Reasons given for unemployment such as dismissal (4.3%), quit (27.7%), hesitation to employ (42.5%)and discontinuance of job (25.5%) were basically due to epilepsy. 7) About half(46.2%) of all patients have become Christian since the Rose Club was a voluntary agency which has been sponsored by Christians. 8) 82. 6% of patients were diagnosed as having grand mal as the most. 9) 29.4% of patients explained aura with psychomotor disturbances and 13.8% with sensory disorders. 10) 46.3% of patients were attacked with seizures when they were tired and others(11.6% and 4.9%) after excessive eating and hunger. 11) Patients suffered more seizures in spring and summer rather than in autumn and winter and most patients had attacks 1-5 times a month. 12) For etiologic reasons of epilepsy, 35.5% of patients considered it was caused by psychological stress and 11.5% by trauma. Only 1.1% of patients considered it as having hereditary components. 13) 51% of patients were slow in caring for their own illnesses. They started to reat epilepsy after spending 5 years of time from the initial seizure. Only 5.4% of patients had received the modern anti-epileptic therapy right after the nitial seizure. 14) 62.1% of patients had no therapy or irregular or incomplete treatment before registration at the Rose Club Clinic. 15) Before registration at the Rose Club, 42.4% of patients received medical care. On the other hand, 25.6% went to herb doctors and 12.5% used to go to the drugstore in order to get anti-epileptic drugs. 16) 41. 6% of patients who took anti-epileptic drugs had more or less side-effects. Indigestion was the most common. 17) For continuation of treatment, 30.3% have received treatment for more than 5 years and the evident showed that epilepsy took a longer time to be cured. 18) Regarding the medical care received 44.2% of patients were very satisfied with effective care and 26.5% felt as good. 19) For attitudes toward epilepsy. 27.0% of patients and 68.2% of patients family were pessimistic. 20) 65.9% of patients had optimistic attitudes toward effectiveness of medical care of epilepsy. 21) 64.8% of wives and husbands had better understanding and cooperative for their spouses who had epilepsy. 22) 33.3% of patients were under-treated at the place of work. 23) 70.2% of patients wished to marry when they reach childbearing age and 63% wished to have children. Through the above results it is recommended for nation-wide epilepsy control that the sound and correct health education not only from health aspect but also from welfare aspect should be planned and implemented as soon as possible.
