Modeling seizures: from single neurons to networks
Epilepsies are defined by the occurrence of spontaneous and recurrent seizures . Seizures are characterized by electrophysiological (field potential) signatures, varying from one patient to the next and even within a given patient . Given such variability, it is important to rely on a taxonomy of seizures, not only for mechanistic studies (different seizures may be associated with different underlying mechanisms, hence to different pharmacotherapy) but also for diagnostic purposes (particularly for presurgical evaluation in the case of drug-resistant epilepsies).

Processed EEG from depth of anaesthesia monitors and seizures: a scoping review
Electrographic monitoring is an important aspect of the management of epileptic seizures. This is particularly true in cases of status epilepticus, when continued seizure activity for more than five minutes, or recurrent events without recovery in between, are linked to a significant risk of cerebral damage [1,2], making the prevention of prolonged convulsion a priority. Those patients whose seizures are not terminated by initial therapies (benzodiazepines, rapid loading of anticonvulsant) require general anaesthesia and admission to critical care environment, and represent those most likely to suffer irreversible damage. ...

Female Preponderance in Genetic Generalized Epilepsies
Epilepsy is a common neurological disorder affecting 45.9 million individuals worldwide1. Sex is usually not considered a susceptibility factor for epilepsy, but differences in epilepsy incidence and prevalence between men and women have been reported2-6. It is slightly more prevalent in men (329.3 per 100.000 population) than in women (318.9 per 100.00 population)1. Men with epilepsy have higher disability-adjusted life-years rates (201.2 per 100.000 population) and higher mortality rates (2.09 per 100000) than women (163.6 per 100000 population and 1.4 per 100000, respectively)1.

Distinct changes of brain cortical thickness relate to post-treatment outcomes in children with epilepsy
Neuroimaging provides an alternative for the visualisation of brain changes in patients with epilepsy in vivo [1, 2], but the neurobiological heterogeneity of the illness precludes clinical translations and genetic research of neuroimaging findings. In addition, treatments with medications, substance abuse, and varying illness durations may cause inconsistency across studies and limit the effectiveness of magnetic resonance imaging (MRI) data as biomarkers for individual identification and outcome prediction.

Age-related Evolution of EEG in Dravet Syndrome: Meta-Analysis of 155 Patients
Dravet syndrome (DS) is an infantile-onset developmental and epileptic encephalopathy characterized by febrile seizures in the first year of life, followed by the appearance of afebrile seizures of varying semiologies which are almost always drug-resistant.1 Approximately 80-90% of patients have SCN1A pathogenic variants.2 EEG is typically normal at the time of first presentation, but various abnormalities may be seen later, including generalized or focal slowing, generalized spike-wave, and focal or multifocal spikes or spike-wave discharges.

EPM2A in-frame deletion slows neurological decline in Lafora Disease
Lafora Disease is an autosomal recessive progressive myoclonus epilepsy with onset in teen age and death within 10 years. By age 20, patients are commonly debilitated with near-constant myoclonus associated with atypical absences interrupting every thought and spoken sentence, have significant cognitive decline and are wheelchair bound. The disease is caused by mutations in either the EPM2A gene encoding the laforin glycogen phosphatase or the EPM2B gene coding for the malin ubiquitin E3 ligase .

Looks can be deceptive: A primary generalized epilepsy mimicking a lesional focal-reflex epilepsy
Seizure semiology, the clinical phenomenon which occur during seizures, is the most effective way to identify the type of seizure in patients with epilepsy. Identifying the epilepsy type based on semiology and EEG abnormalities is crucial in diagnosing and choosing the appropriate therapy. Although epilepsies are traditionally divided into "focal" and "generalized ”, epilepsy is conceptualized as a network disorder.1 Recent publications have reported focal features among patients with genetic generalized epilepsy (GGE) in the domains of semiology, electroencephalography, neuropsychology, neuropathology...

Identification and Successful Management of Near-Lethal Ventricular Tachycardia in 2q24 Deletion-Associated Developmental and Epileptic Encephalopathy
2q24 deletion syndrome is characterized by severe epilepsy phenotypes, seizure onset during infancy, and developmental delays (1)(see supplementary reading list). It also includes head, facial, limb, and whole-body dysmorphic features, as well as cardiac structural abnormalities (e.g., hypoplastic left heart& atrial septal defects). Chromosome 2q24 encodes many proteins of the sodium channel family. 2q24 deletion syndrome has some overlap with Dravet Syndrome (DS), which is another severe developmental epileptic encephalopathy (DEE), in which the majority are due to mutations in the sodium channel gene, SCN1A.

The effect of ketogenic diet on serum lipid concentrations in children with drug resistant epilepsy
The ketogenic diet (KD), a high-fat, adequate protein, and low-carbohydrate diet, is one of the most effective alternative treatment options for children with medication-resistant epilepsy.1 Fat content of the diet provides up to 90% of calories. Thus, KD is not a simple dietary regulation, but a form of medical therapy that causes major changes in energy metabolism and therefore can cause many side effects such as constipation, kidney stones and dyslipidemia.2 Previous short-term studies reporting elevated blood lipids and adverse effects on the cardiovascular system raise concerns about dyslipidemia and potential cardiov...

Reply to Braun et al. “Novel bathing epilepsy in a patient with 2q22.3q23.2 deletion”
Reflex seizures are epileptic events triggered by specific motor, sensory or cognitive stimulation and are associated with different genetic and acquired aetiologies (1). In particular, the genetic background of reflex seizures and epilepsies is largely heterogeneous and mostly unknown with no major gene identified in humans (2). The two forms of reflex epilepsy related to bathing, namely, hot water epilepsy (HWE) and bathing epilepsy (BE), share some semiology and epidemiological features and have a strong but different genetic background.

Antiepileptic drugs and serotonin syndrome- A systematic review of case series and case reports
Serotonin syndrome (SS) is an iatrogenic drug ‑induced clinical syndrome characterized by a combination of altered mental activity, neuromuscular abnormalities, and autonomic disturbances. Serotonin syndrome typically results from the increased intrasynaptic concentration of serotonin or 5-hydroxytryptamine (5-HT). There are seven types of 5- HT receptors (5-HT1 to 5-HT7), each with several subtypes. The 5-HT2A and 5-HT1A are the two main receptors implicated in the pathophysiology of SS .

No evidence that SCN9A variants are associated with epilepsy
Voltage gated sodium channels play a vital part in neuronal signalling pathways throughout the nervous system. The main brain expressed sodium channels are SCN1A, SCN2A, SCN3A and SCN8A. Pathogenic variants in these genes lead to well-defined epilepsy syndromes including early onset developmental and epileptic encephalopathies as well as milder phenotypes . In contrast SCN9A, SCN10A and SCN11A are primarily expressed in dorsal root ganglion and sympathetic ganglion neurons of the peripheral nervous system playing an important role in peripheral pain-signalling pathways .

Febrile seizure: what information can caregivers access through YouTube?
Febrile seizures are the most common seizures accompanying fever that occur in children (1). The age of onset is under 5 years of age in 95% of cases, and the onset is associated with neurological immaturity, not acute brain lesions. Febrile seizures are classified into simple febrile seizures and complex febrile seizures, and simple febrile seizures represent 65 to 90% of all febrile seizures (2). Although simple febrile seizure is a benign event, and in most cases, the patient recovers without any sequelae (1), the general public or laypeople feel extreme fear and anxiety when they observe a child experiencing a febrile ...

Randomized trial of high-dose pyridoxine in combination with standard hormonal therapy in West syndrome
West Syndrome (WS) is a distinct, age-dependent, developmental and epileptic encephalopathy of infancy with poor neurodevelopmental outcome. The first-line therapeutic options are hormonal therapy (adrenocorticotropic hormone [ACTH] or oral steroids), vigabatrin or a combination of the two as suggested by the high quality of clinical evidence [1,2]. The short-term efficacy of hormonal therapy to eliminate epileptic spasms is variable among studies ranging from 37% to 73% [3,4]. Hormonal therapy has also been observed to be superior to vigabatrin therapy (76% versus 54%) . (Source: Seizure: European Journal of Epilepsy)

Decisive evidence of direct effect of ACTH treatment in West syndrome: A case report
In patients with West syndrome, the administration of exogenous adrenocorticotropic hormone (ACTH) is considered a potent and effective treatment . Exogenously administered ACTH hyperactivates the hypothalamic-pituitary-adrenal axis (Fig. 1A); however, the resulting hormonal changes cannot fully account for the therapeutic effect of ACTH. Indeed, the administration of corticosteroids to patients with West syndrome failed to provide an anti-epileptic effect comparable to that of ACTH . Thus, the antiepileptic effect of ACTH in West syndrome has been postulated to involve a direct action of ACTH on the central nervous ...

Reflex seizures occur in response to a variety of stimuli from the common (e.g. light) to the rare (e.g. orgasms). Two forms of reflex epilepsy related to bathing are well described: 1. “hot water epilepsy” (HWE), where seizures are triggered by the act of immersing the head under hot water and 2. “bathing epilepsy” where seizures are provoked by body immersion in lukewarm water (Yalcin et al., 2006). Both have a characteristic semiology and epidemiology and are more common in males in India and Turkey, with a strong genetic susceptibility. (Source: Seizure: European Journal of Epilepsy)

Thumb-up sign: characterization of an undescribed seizure semiologic sign.
In temporal lobe epilepsy, dystonic posturing of the body has been described as a lateralizing sign contralateral to the epileptic hemisphere in focal onset seizures with impaired awareness (Kotagal P, Luders H, Morris HH, Dinner DS, Wyllie E and Of 1989).

A novel scale for suspicion of psychogenic nonepileptic seizures: development and accuracy
Psychogenic nonepileptic seizures (PNES), also known as dissociative seizures, are paroxysms of altered subjective experience, involuntary movements or reduced self-control resembling epileptic seizures, yet unrelated to ictal epileptiform discharges . Early identification shortens disease duration, optimizes counseling and improves prognosis. Despite this, accurate diagnosis of PNES may take up to 8 years, a fact mainly associated with health care providers ’ education and inadequacies of the health care system [2,3].

Combining perampanel and ketamine in super refractory post-traumatic status epilepticus: a case report
Status Epilepticus (SE) is a condition resulting either from the failure of seizure termination mechanisms or from the abnormal activation of prolonged seizure mechanisms. It represents a life-threatening medical emergency associated with high morbidity and mortality that requires prompt diagnosis and treatment. SE treatment begins with a quick-acting benzodiazepine, followed by intravenous (IV) loading and a continuous infusion of antiseizure medications (ASMs). The failure of first- and second-line treatments is defined as “refractory SE” (RSE) and requires infusion of IV anaesthetics. (Source: Seizure: Europ...

Reciprocal burden: Adults with drug-resistant epilepsy reflect upon informal caregiver support.
Drug-resistant epilepsy (DRE) is serious disorder characterized by unpredictable and intrusive seizures. Due to uncontrolled seizures, poor memory and cognitive deficits, family caregivers have to be relied upon for disease management and emotional support . As a consequence, epilepsy is as much a focus of the lives of caregivers, as it is for those diagnosed with the condition [2-4]. Caregiving is frequently subtle and varied, both with respect to how carers identify with the role and the tasks they undertake. (Source: Seizure: European Journal of Epilepsy)

Efficacy and tolerability of a whey-based, medium-chain triglyceride –enhanced ketogenic formula in children with refractory epilepsy: a retrospective study
Ketogenic metabolic therapy (KMT) is a term coined by Beth Zupac-Kania in 2016 to describe the variety of dietary therapies that restrict carbohydrate intake and liberalize dietary fat intake to stimulate nutritional ketosis . Nutritional ketosis occurs when the body metabolizes fat in the absence of adequate carbohydrates for energy production via glycolysis. A meta-analysis of 38 studies reviewed the therapeutic efficacy of KMT for epilepsy and calculated a weighted success rate of 58.4% (95% CI, 48.7-69.9%), with success defined as a reduction of seizures by at least 50% at 3 months .

Prevalence and mortality of epilepsies with convulsive and non-convulsive seizures in Kilifi, Kenya
Epilepsy is one of the most common chronic neurological disorders and is an important public health problem affecting close to 70 million people worldwide . This number approximates about 0.7% of the global burden of disease and contributes up to 17 million disability adjusted life-years (DALYs) annually . Up to 90% of the people with epilepsy (PWE) reside in low and middle income countries (LMICs) , with 20% of the global burden in Africa alone . Another 500 million people are affected indirectly as parents, relatives and friends . (Source: Seizure: European Journal of Epilepsy)

Genotype-phenotype implications from three representative clinical FOXG1 variants associated with FOXG1 syndrome
FOXG1 (Forkhead Box G1) gene, as its name indicates, encodes a transcription factor with a Forkhead DNA-binding domain. FoxG1 protein is highly conserved among mammalian and reptilian species, with DNA-binding and C-terminal domains showing highest conservation, whereas its N-terminal domain contains a mammal-specific extended proline- and glutamine-rich region . The neurodevelopmental disorder associated with heterozygous variants in FOXG1 gene is referred as FOXG1 syndrome (OMIM #613454), equivalent to the original designation of “congenital variant of Rett syndrome.”  The main clinical features of FOXG...

Neuromagnetic High Frequency Spikes Are a New and Noninvasive Biomarker for Localization of Epileptogenic Zones
Recent advances in epilepsy research have revealed that the epileptic brain generates high frequency brain signals (HFBS,> 80 Hz), which can be detected invasively [1 –5] and noninvasively [6–9]. Invasive recordings [1–5] have provided solid evidence that HFBS play an important role in epileptogenesis and epileptogenicity. The resection of the brain areas generating HFBS can predict favorable outcomes of epilepsy surgery [10–12]. Noninvasive technologies, such as magnetoencephalography (MEG) and scalp electroencephalography (EEG), have shown promising results for detection and localization of HFB...
