Objectives The aim of this study was to investigate the impact of clinical and psychological factors on the quality of life of children and adolescents with epilepsy and their families. Methods Children and adolescents with epilepsy and their families (n = 63, age range = 6-17 years) completed questionnaires on epilepsy-related variables, quality of life, children's depressive symptoms, children's anxiety, children's behavioral problems, children's attention problems, parental stress, and parental anxiety. Stepwise regression analysis was performed to determine the significant predictive variables that affect quality of life. Results In the correlational analysis, children's attention problems (r = 0.363, p = 0.004), parental anxiety (r = 0.377, p = 0.003), parental stress (r = 0.564, p < 0.001), and children's behavioral problems (r = 0.503, p < 0.001) showed a significant correlation with quality of life. Parental stress (β = 0.415, p = 0.001, adjusted R² = 0.345) and children's behavioral problems (β = 0.285, p = 0.02, adjusted R² = 0.345) were significantly related to the quality of life. Conclusions Clinicians should pay attention to parental stress and children's behavioral problems, which affect quality of life in families with pediatric epilepsy.

Syncopes are the most common non-epileptic attacks mimicking epileptic seizures. Among them, cardiogenic syncope is potentially life threatening. A 49 year old man was refered for the recurrent episodes of loss of consciousness with tonic posture and upward eyes deviation. The electrocardiogram showed polymorphologic ventricular tachycardia during attacks, which normalized after that. He was treated with isoproterenol and symptoms subsided. Here, we report a case of ventricular tachycardia manifested as epileptic seizures.

Objectives : To assess and compare the effectiveness of acupuncture treatment of depression in epilepsy children and adolescent's parents. Methods : 20 cases of depression in epilepsy children and adolescent's parents were investigated in Southern TCM Centre, Southern University College, Malaysia. Subjects were randomly divided into two groups; Acupuncture treatment group and Herbal medication treatment group. Family relationships questionnaires and Hamilton Depression Rating Scale were used before, after 4 weeks and 8 weeks treatments in order to investigate the effectiveness of treatment. Results : After 4 weeks Acupuncture treatment group showed significant reduction in the Hamilton Depression Rating Scale. On the other hand, after 8 weeks both groups showed significant reduction in Hamilton Depression Rating Scale. Conclusions : The result suggests that the effectiveness of Acupuncture treatment is comparable with treat of Herbal medication treatment to reduce parent's Hamilton Depression Rating Scale.

뇌전증은 반복적으로 발작이 발생하는 질환으로, 뇌파검사가 가장 객관적이고 유용한 검사이다. 본 연구의 대상자는 2014년 서울대학교 병원에서 뇌전증 확진판정을 받고 뇌파 검사를 받은 환자를 대상으로 연구목적에 동의한 244명을 대상으로 하였다. 이 중 뇌파 검사결과에 따라 성별과 연령에 상관없이 정상그룹 122명, 비정상그룹 122명을 대상으로 뇌파소견과 혈구산정검사와의 상관관계를 알아보고자 하였다. 이번 연구에서 분석된 뇌파 측정결과와 혈구산정검사 결과와의 유의한 상관관계는 WBC, RBC, neutrophil, lymphocyte로 4항목이었다. WBC (p<0.05)와 neutrophil (p<0.01)은 양의 관계였으며, RBC (p<0.05)와 Lymphocyte (p<0.01)는 음의 관계로 나타났다. 이 논문의 한계점은 항뇌전증 치료제의 종류에 따른 혈구산정 검사결과를 분석하지 못한 것이다. 하지만 동일한 질환에 따른 뇌파결과를 중심으로 분석한 결과는 의미가 있다. 그러므로 이러한 부분은 향후 더욱 많은 데이터를 통계적으로 분석해야 할 필요성이 있다고 생각된다.

여러가지 약물에도 발작의 증세가 조절되지 않는 난치성 뇌전증 환자에서 다양한 치료법들을 시도해 볼 수 있다. 하지만 그 중 수술적인 방법이 필요한 환자에서는 수술 전 검사를 통해 발작부위의 절제부분을 결정한다. 정확한 병변의 측정과 안전한 수술을 위해 뇌 피질에 전극 삽입술을 시행한다. 피질에 삽입된 전극으로 단순히 뇌파만을 기록하는 것이 아니라 다양한 검사를 시도해 그 부위가 갖는 기능을 확인할 수 있고 그런 검사법 중 하나로 유발전위 검사법이 있다. 2015년 1월부터 2018년 12월까지 70명의 환자를 대상으로 측정된 파형의 경향이 의미하는 바를 분석하였다. 뇌 피질에 삽입된 전극에서 기록된 체성감각유발전위는 중심고랑의 주행경로를 찾아 일차운동영역 및 일차감각영역을 피해 수술 할 수 있다. 또한 청각유발전위와 시각유발전위를 이용해 청각피질과 시각피질에서 기능적 피질의 확인과 뇌파검사상 나타난 발작초점부위와의 관계를 비교해 절제부위를 결정하는데 도움을 주고 수술 후에 발생할 수 있는 기능적 장애를 최소화 할 수 있다.

Epilepsy has continued to provide challenges to epileptologists, as a significant proportion of patients continue to suffer from seizures despite medical and surgical treatments. Deep brain stimulation (DBS) has emerged as a new therapeutic modality that has the potential to improve quality of life and occasionally be curative for patients with medically refractory epilepsy who are not surgical candidates. Several groups have used DBS in drug-resistant epilepsy cases for which resective surgery cannot be applied. The promising subcortical brain structures are anterior and centromedian nucleus of the thalamus, subthalamic nucleus, and other nuclei to treat epilepsy in light of previous clinical and experimental data. Recently two randomized trials of neurostimulation for controlling refractory epilepsy employed the strategies to stimulate electrodes placed on both anterior thalamic nuclei or near seizure foci in response to electroencephalographically detected epileptiform activity. However, the more large-scale, long-term clinical trials which elucidates optimal stimulation parameters, ideal selection criteria for epilepsy DBS should be performed before long. In order to continue to advance the frontier of this field, it is imperative to have a good grasp of the current body of knowledge.

In this paper, the new architecture of seizure prediction using CNN and LSTM and DWT was presented. In the proposed architecture, EEG data was labeled into a preictal and interictal section, and DWT was adopted to the preprocessing process to apply the characteristics of the time and frequency domain of the processed EEG signal. Also, CNN was applied to extract the spatial characteristics of each electrode used for EEG measurement, and LSTM neural network was applied to verify the logical order of the preictal section. The learning of the proposed architecture utilizes the CHB-MIT Scalp EEG dataset, and the sliding window technique is applied to balance the dataset between the number of interictal sections and the number of preictal sections. As a result of the simulation of the proposed architecture, a sensitivity of 81.22% and an FPR of 0.174 were obtained.

Objectives : The aim of this study was to estimate the prevalences of electroencephalographic (EEG) abnormalities and epilepsy in children and adolescents with autism spectrum disorder (ASD). In addition, we intended to identify demographic and clinical correlates of epilepsy in ASD. Methods : A total of 140 children and adolescents (age $7.3{\pm}4.8yrs$, 106 boys) with ASD underwent EEG from January 2010 to December 2013 at Asan Medical Center. Medical records were reviewed for demographic information, clinical characteristics, psychiatric diagnoses and comorbidities, EEG findings and neurological diagnoses. Results : The prevalences of EEG abnormalities and epilepsy in children and adolescents with ASD was 62.1% and 38.6%, respectively. In subjects with seizure-like movements, EEG abnormalities and epilepsy were more frequent than those without seizure-like movements (EEG abnormalities : 92.5% vs. 43.7%, p<.001 ; epilepsy : 90.6% vs. 5.7%, p<.001). ASD subjects who had epilepsy were older (p=.001), had lower full scale intelligence quotient (p<.001) and took more antipsychotics (p=.006) than those who did not. Conclusion : The prevalences of EEG abnormalities and epilepsy in our sample were similar to those from Western countries. Our results suggested a possible association of older age, lower intelligence quotient, and antipsychotics use with epilepsy in ASD. Conduct of further prospective study in a larger sample is needed.

Epilepsy is a chronic neurological disease which produces repeated seizures. Over 30% of epileptic patients cannot be treated with anti-epileptic drugs, and surgical resection may cause loss of brain functions. Seizure suppression by electrical stimulation is currently being investigated as a new treatment method as clinical evidence has shown that electrical stimulation to brain could suppress seizure activity. In this paper, design of a real-time closed-loop neurostimulation system for epileptic seizure suppression is presented. The system records neural signals, detects seizures and delivers electrical stimulation. The system consists of a 6-channel electrode, front-end amplifiers, a data acquisition board by National Instruments, and a neurostimulator and Generic Osorio-Frei algorithm was applied for seizure detection. The algorithm was verified through simulation using electroencephalogram data, and the operation of whole system was verified through simulation and in- vivo test.
