Neuronal network oscillations represent a main feature of the brain activity recorded in the EEG under normal and pathological conditions such as epilepsy. Specific oscillations occur between seizures in patients and in animal models of focal epilepsy, and thus they are termed interictal. According to their shape and intrinsic signal frequency, interictal oscillations are classified as spikes and high frequency oscillations (HFOs). Interictal spikes are recorded in the "wideband" EEG signal and consist of large-amplitude events that usually last less than 1 s; HFOs, in contrast, are extracted by amplifying the appropriately filtered EEG signal, and are usually categorized as ripples (80-200 Hz) and fast ripples (250-500 Hz)...

Lhermitte-Duclos disease (LDD) is a neurological disease caused by a hamartomatous lesion in the cerebellum. Clinically, LDD is commonly associated with progressive space-occupying lesion effects in the posterior fossa, increasing intracranial pressure, occlusive hydrocephalus, and focal neurological deficits of adjacent structures. The authors report the case of a 10-year-old boy with LDD who had been suffering from vomiting attacks (VAs). These VAs had been brief in duration but extremely frequent, and they had been resistant to antiemetic drugs since the early postnatal period...

BACKGROUND: Valproic acid (VPA) is an antiepileptic drug, used for focal and generalized seizure. VPA treatment resulted in significant weight gain but there are no systematic data about the prevalence of this side effect. The aim of the study is to evaluate the weight gain of a paediatric population with epilepsy. METHODS: We enrolled 38 patients, 17 female and 21 male with a mean age of 8.2±4.4 years. We evaluated data about height, weight and BMI at beginning of treatment and at 24, 36 and 48 months of follow-up...

Retigabine, currently used as antiepileptic drug, has a wide range of potential medical uses. Administration of the drug in patients can lead to QT interval prolongation in the electrocardiogram and to cardiac arrhythmias in rare cases. This suggests that the drug may perturb the electrical properties of the heart, and the underlying mechanisms were investigated here. Effects of retigabine on currents through human cardiac ion channels, heterologously expressed in tsA-201 cells, were studied in whole-cell patch-clamp experiments...

OBJECTIVE: Despite the cost saving role of generic anti-epileptic drugs (AEDs), debate exists as to whether generic substitution of branded AEDs may lead to therapeutic failure and increased toxicity. This study compared adverse event (AE) reporting rates for brand vs. authorized generic (AG) vs. generic AEDs. Since AGs are pharmaceutically identical to brand but perceived as generics, the generic vs. AG comparison minimized potential bias against generics. METHODS: Events reported to the U...

Between 2009 and 2012 there were 26 epilepsy-related deaths in the UK of women who were pregnant or in the first post-partum year. The number of pregnancy-related deaths in women with epilepsy (WWE) has been increasing. Expert assessment suggests that most epilepsy-related deaths in pregnancy were preventable and attributable to poor seizure control. While prevention of seizures during pregnancy is important, a balance must be struck between seizure control and the teratogenic potential of antiepileptic drugs (AEDs)...

Driving under the influence of drugs (DUID) is a worldwide problem. Several countries adopted DUID legislations which prove their deterrent effect and impact on road safety. However, use of new psychoactive substances (NPS) and prescription drugs is not known as the applied roadside screening tests are not yet adapted for these compounds. In this study, 558 blood samples obtained during roadside controls in Belgium (January to August 2015) after a positive Drugwipe 5S® test and 199 oral fluid (OF) samples obtained from negatively screened test pads were analyzed...

BACKGROUND: Hypersensitivity is a rare adverse drug reaction (ADR) associated with anti-epileptic medications. Phenytoin is one of the commonly used drugs for treatment of epilepsy that encounters a hypersensitivity reaction. This reaction can be ranged from mild cutaneous rash to anticonvulsant hypersensitivity syndrome (AHS) or drug reaction with eosinophilia and systemic symptoms (DRESS) that includes fever, rash, eosinophilia and involvement of multiple internal organs.

Prevalence of obesity and its related morbidity have increased to alarming levels in adults and children in the United States and globally. Weight loss results in improvement of much of the obesity-related morbidity. Lifestyle changes such as dietary modifications, increased physical activity, and behavioral therapy form the crux of weight management. However, many individuals need additional assistance (pharmacologic or surgical) to initiate or sustain weight loss. Pharmacologic therapy consists of a number of agents that work by decreasing appetite, gastric emptying, or nutrient absorption or by increasing satiety...

AIMS: To evaluate the association between diabetes mellitus (DM) and risk of seizures in a well-defined elderly population. METHODS: The administrative databases of the Lombardy region (a 10 million population area in Northern Italy) were used to identify persons aged 65 years or older with DM (defined by prescription of antidiabetic drugs and/or through ICD-9 CM code and/or exemption code for diabetes) during the year 2002. Seizure-free DM subjects were followed until 2012 in search of individuals with incident seizures (identified through ICD-9 CM codes for epilepsy/seizures or ATC codes for antiepileptic drugs associated with the prescription of an electroencephalogram)...

Limbic encephalitis (LE) is an autoimmune or paraneoplastic disease that affects the medial temporal lobes. The patient will usually present with cognitive impairment, psychiatric changes, and seizures. Autoimmune limbic encephalitis (LE) is a challenging diagnosis as it is not always included in the typical paraneoplastic/autoimmune panels. Anti-GAD antibodies are associated with various disease including type I diabetes mellitus, various autoimmune processes, some neoplastic and infectious diseases. Thus, it is not as specific as some of the antibodies causing LE...

Psychiatric disorders are relatively frequent comorbidities in epilepsy and they have an impact on morbidity, mortality, and quality of life. This is a report from the Task Force on Education of the ILAE Commission on Neuropsychiatry based on a survey about educational needs of epileptologists regarding management of the psychiatric comorbidities of epilepsy. The Task Force designed a quantitative questionnaire to survey the self-perceived confidence of child and adult epileptologists and psychiatrists in managing major psychiatric comorbidities of epilepsy to identify: (1) critical areas of improvement from a list of skills that are usually considered necessary for effective management of these conditions, and (2) the preferred educational format for improving these skills...

Meningiomas are the commonest type of primary brain tumours. Whilst most patients are seizure-free prior to surgery, antiepileptic drugs are frequently administered to reduce the risk of developing post-operative seizures. However, evidence to support their efficacy in providing this outcome is sparse. To this end, we performed a systematic review to assess the impact of prophylactic antiepileptic drugs on post-operative epilepsy rates in seizure-naïve patients undergoing craniotomy for resection of meningiomas...

OBJECTIVE: Brain tumor-related epilepsy (BTRE) is often drug resistant and patients can be forced to take polytherapy that can adversely affect their quality of life (QoL). Lacosamide (LCM) is a new antiepileptic drug (AED) used as adjunctive therapy in patients with partial seizures with or without secondary generalization, with a favorable pharmacokinetic profile that seems to be effective and well tolerated. Therefore it represents a possible therapeutic choice for patients with BTRE...

Voltage-gated sodium channels are critical for neuronal activity, and highly intolerant to variation. Even mutations that cause subtle changes in the activity these channels are sufficient to cause devastating inherited neurological diseases, such as epilepsy and pain. However, these channels do vary in healthy tissue. Alternative splicing modifies sodium channels, but the functional relevance and adaptive significance of this splicing remain poorly understood. Here we use a conserved alternate exon encoding part of the first domain of sodium channels to compare how splicing modifies different channels, and to ask whether the functional consequences of this splicing have been preserved in different genes...
