Focal cortical dysplasia (FCD) is the major cause of intractable focal epilepsy in childhood leading to epilepsy surgery. The overall seizure freedom after surgery ranges between 50-75% at 2 years after surgery and the long-term seizure freedom remain relatively stable. Seizure outcome after surgery depends on a various factors such as pathologic etiologies, extent of lesion, and types of surgery. Therefore, seizure outcome after surgery for FCD should be analyzed carefully considering cohorts' characteristics. Studies of pediatric epilepsy surgery emphasize the early surgical intervention for a better cognition. Early surgical intervention and cessation of seizure activity are important for children with intractable epilepsy. However, there are limited data on the cognitive outcome after surgery in pediatric FCD, requiring further investigation. This paper reviews the seizure and cognitive outcomes of epilepsy surgery for FCD in children. Several prognostic factors influencing seizure outcome after surgery will be discussed in detail.

Seizure can be categorized in various ways. Seizures are divided into those that are generalized and those affecting only part of the brain (focal seizure). Focal (partial) seizures are subdivided into simple seizures and complex seizures. Simple focal seizures may be manifested by focal motor, sensory or autonomic symptoms and consciousness is preserved. The above symptoms may be preceded, accompanied or followed by, and consciousness is impaired in, complex focal seizures. Ictal aphasia can arise from epileptiform discharge on cortical language areas. Generally next to the ictal aphasia, generalized seizures occur, but without losing consciousness, only aphasia takes place. A 61-year-old woman was admitted due to ictal aphasia and facial spasm, and she showed a little palpitation and was startled easily. We diagnosed her as Shimdamgiheo (心膽氣虛) and Damhwashimyo (痰火心擾), so we prescribed Chungsimondam-tang. It was effective on that case. so we report.

Objective : This study was designed to analyze seizure outcome and to investigate the prognostic factors for predicting seizure outcome according to the preoperative evaluations, surgical procedures, topectomy sites and histopathological findings in patients with extratemporal lobe epilepsy [ETLE]. Methods : This study comprised 63 patients with ETLE who underwent surgery. Preoperative evaluations included semiologic analysis, chronic video-EEG monitoring, and neuroimaging studies. Surgical procedures consisted of topectomy in 51 patients, corpus callosotomy in 9, functional hemispherectomy in 2, and vagus nerve stimulation [VNS] in 1. Histopathological findings were reviewed. Postoperative seizure outcomes were assessed by Engel's classification at the average follow up period of 66.8 months. Chi-square test was used for statistics. Results : Total postoperative seizure outcomes were class I in 51 [80%] patients, class II in 6 [10%], class III in 6 [10%]. Patients with structural abnormalities on neuroimaging study showed class I in 49 [88%] patients [p<0.05]. Patients with focal and regional ictal EEG onset revealed class I in 47 [90%] patients [p<0.05]. Semiologic findings, surgical procedures, topectomy sites and histopathological findings did not show statistical correlation with seizure outcome [p<0.05]. Conclusion : A good seizure outcome was obtained in patients with ETLE. The factors for favorable seizure outcome are related to the presence of structural abnormalities on neuroimaging study, and focal and regional ictal EEG onset.

Objectives The prognosis, recurrence rate and treatment of febrile seizure were studied through the research of recent western medicine and Chinese oriental medicine paper. Methods Recent western medicine paper of internal and external and chinese oriental medicine paper from 1999 to 2007 were investigated. Results and Conclusions The prognosis of febrile seizure was good in most cases, but children with febrile seizure who developed epilepsy range between 2 and 10%. The risk factors developed epilepsy including complex febrile seizure, focal and prolonged seizure, pre-existing neurodevelopmental abnormalities and recurrent febrile seizure. Recurrence rate of febrile seizure ranges between 30 and 50% was high. The risk factors can be predicted by their age at first febrile seizure happened, family medical history of febrile seizure and epilepsy, complex febrile seizure, and neurodevelopmental abnormalities. However, the most important factor of those is the age when they have first febrile seizure. Diazepam or Lorazepam was administrated for a child with prolonged seizure but only Diazepam was used for reducing recurrence of febrile seizurein febrile illness. However, there were some side effects such as lethargy, ataxia, and irritability. The study of chinese oriental medicine demonstrates that the acupuncture and venesection were used for seizure attack and reduced of recurrences and second attack. To reduce recurrence of febrile seizure, herbal medicine was also used for febrile illness or after seizure attack within a certain period of time, so reduce the recurrence, frequency of seizure and febrile illness. The most of herbs in prescription were used for removing heat and toxic meterials(淸熱解毒), extinguishing wind and to stopping the convulsion(熄風止痙)

Low-grade epilepsy-associated neuroepithelial tumors (LEATs) are responsible for drug-resistant chronic focal epilepsy, and are the second-most common reason for epilepsy surgery in children. LEATs are extremely responsive to surgical treatment, and therefore epilepsy surgery should be considered as a treatment option for LEATs. However, the optimal time for surgery remains controversial, and surgeries are often delayed. In this review, we reviewed published article on the factors associated with seizure and cognitive outcomes after epilepsy surgery for LEATs in children to help clinicians in their decision whether to pursue epilepsy surgery for LEATs. The achievement of gross total resection may be the most important prognostic factor for seizure freedom. A shorter duration of epilepsy, a younger age at surgery, and extended resection of temporal lobe tumors have also been suggested as favorable prognostic factors in terms of seizure control. Poor cognitive function in children with LEATs is associated with a longer duration of epilepsy and a younger age at seizure onset.

The major purpose of this study is to evaluate the classification of epileptic seizure types and epilepsy described in the literatures of both Western and East Asian medicine, especially based on the two criteria- a theoretical and a practical aspect of the classification systems. Currently, the 1981 classification of epileptic seizure types, and the 1989 classification of epilepsy syndromes and epilepsies which were proposed and approved by the International League Against Epilepsy(ILAE) have been generally accepted worldwide, although a variety of modifications have been consistently suggested. A large proportion of epilepsy cases cannot be easily classified as either 'focal' or 'generalized' or as either 'symptomatic' or 'idiopathic', so they fail to be precisely fallen into any of the ILAE categories. Terms and concepts used in the East Asian medicine are also inadequate to identify epileptic seizure types and epilepsy syndromes as discrete diagnostic entities because of ambiguities in definition and use. Therefore, this article suggests an alternative approach not only more helpful in understanding mechanism of epilepsy but also more easily applicable and effective in clinical value.

Genetic causes of developmental and epileptic encephalopathy (DEE) have been rapidly uncovered from mid-2010s. The mutations of gene enconding calcium channel, voltage-dependent, P/Q type, alpha 1A subunit (CACNA1A) are recently detected in DEE, which gene is already known well in familial hemiplegic migrine type 1 or episodic ataxia type 2. Ketogenic diet therapy (KDT) is effective in some DEE, which data is short in CACNA1A encephalopathy. A 3-month-old male with global developmental delay and multidrug-resistant focal seizures was diagnosed as epilepsy of infancy with migrating focal seizures (EIMFS). Brain magnetic resonance imaging and metabolic screening were all normal. Whole exome sequencing revealed two variants of CACNA1A: c.899A>C, and c.2808del that is from his mother. His seizures disappeared within 3 days whenever on KDT, which recurred without it. To our knowledge, this rare case of EIMFS with novel mutations of CACNA1A, is the first report in CACNA1A encephalopathy becoming seizure-free on KDT.

Temporal lobe epilepsy (TLE) is the most common type of medically intractable epilepsy in adults and children, and mesial temporal sclerosis is the most common underlying cause of TLE. Unlike in the case of adults, TLE in infants and young children often has etiologies other than mesial temporal sclerosis, such as tumors, cortical dysplasia, trauma, and vascular malformations. Differences in seizure semiology have also been reported. Motor manifestations are prominent in infants and young children, but they become less obvious with increasing age. Further, automatisms tend to become increasingly complex with age. However, in childhood and especially in adolescence, the clinical manifestations are similar to those of the adult population. Selective amygdalohippocampectomy can lead to excellent postoperative seizure outcome in adults, but favorable results have been seen in children as well. Anterior temporal lobectomy may prove to be a more successful surgery than amygdalohippocampectomy in children with intractable TLE. The presence of a focal brain lesion on magnetic resonance imaging is one of the most reliable independent predictors of a good postoperative seizure outcome. Seizure-free status is the most important predictor of improved psychosocial outcome with advanced quality of life and a lower proportion of disability among adults and children. Since the brain is more plastic during infancy and early childhood, recovery is promoted. In contrast, long epilepsy duration is an important risk factor for surgically refractory seizures. Therefore, patients with medically intractable TLE should undergo surgery as early as possible.

Epilepsy has been known to humankind since antiquity. The surgical treatment of epilepsy began in the early days of neurosurgery and has developed greatly. Many surgical procedures have stood the test of time. However, clinicians treating epilepsy patients are now witnessing a huge tide of change. In 2017, the classification system for seizure and epilepsy types was revised nearly 36 years after the previous scheme was released. The actual difference between these systems may not be large, but there have been many conceptual changes, and clinicians must bid farewell to old terminology. Paradigms in drug discovery are changing, and novel anti-seizure drugs have been introduced for clinical use. In particular, drugs that target genetic changes harbor greater therapeutic potential than previous screening-based compounds. The concept of focal epilepsy has been challenged, and now epilepsy is regarded as a network disorder. With this novel concept, stereotactic electroencephalography (SEEG) is becoming increasingly popular for the evaluation of dysfunctioning neuronal networks. Minimally invasive ablative therapies using SEEG electrodes and neuromodulatory therapies such as deep brain stimulation and vagus nerve stimulation are widely applied to remedy dysfunctional epilepsy networks. The use of responsive neurostimulation is currently off-label in children with intractable epilepsy.
