Marijuana-based treatment for refractory epilepsy shows promise in surveys, case series and clinical trials. However, literature on their electroencephalography (EEG) effects is sparse. Our objective is to analyze the effect of marijuana on EEG in a 24-year-old patient with idiopathic generalized epilepsy (IGE) treated with cannabis. We blindly reviewed three long-term EEGs-a 24-hour study while only on antiepileptic drugs (AEDs), a 72-hour EEG with Cannabis indica smoked on days one and three in addition to AEDs and a 48-hour EEG with combination C...

BACKGROUND: Perampanel, a new specific non-competitive AMPA receptor antagonist, has been recently approved in the United States and the European Union for the adjunctive treatment of focal seizures and primary generalized tonic-clonic seizures associated with idiopathic generalized epilepsy. A positive relationship between plasma perampanel concentration and improvement in seizure control has been identified in regulatory trials, suggesting that therapeutic drug monitoring (TDM) could be useful in optimizing clinical response in patients with epilepsy treated with perampanel...

Purpose: Childhood absence epilepsy (CAE) is a common syndrome of idiopathic generalized epilepsy. However, little is known about the brain structural changes in this type of epilepsy, especially in the default mode network (DMN) regions. This study aims at using the diffusion tensor imaging (DTI) technique to quantify structural abnormalities of DMN nodes in CAE patients. Method: DTI data were acquired in 14 CAE patients (aged 8.64 ± 2.59 years, seven females and seven males) and 16 age- and sex-matched healthy controls...

Idiopathic generalized epilepsy (IGE) has been linked with disrupted intra-network connectivity of multiple resting-state networks (RSNs); however, whether impairment is present in inter-network interactions between RSNs, remains largely unclear. Here, 50 patients with IGE characterized by generalized tonic-clonic seizures (GTCS) and 50 demographically matched healthy controls underwent resting-state fMRI scans. A dynamic method was implemented to investigate functional network connectivity (FNC) in patients with IGE-GTCS...

We report four children who highlight the potentially under-recognized EEG pattern of bilaterally synchronous occipito-frontal sharp waves, which may occur in children with Panayiotopoulos-type self-limited childhood epilepsy but may be easily confused with the patterns of symptomatic generalized epilepsy. Our patients were young, healthy children who had infrequent, predominantly nocturnal, fairly prolonged seizures characterized by altered consciousness, vomiting, and autonomic features, or in one case nocturnal secondary generalized tonic clonic convulsion...

PURPOSE: To review the long-term outcome of epilepsy in population-based studies. METHOD: Analysis of population-based studies. RESULTS: About two of three patients with new-onset epilepsy will, in the long run, enter five-year terminal remission. Chances for remission are best for those with idiopathic or cryptogenic epilepsy. It is unclear whether the seizure outcome has improved over the last several decades. Social outcome, however, may have become better because of the improved level of knowledge on and public attitudes toward people with epilepsy, and possibly fewer prejudices at home, daycare, school, military and labor market...

Feelings of stigma are one of the main burdens reported by people with epilepsy (PWE). Adults with temporal or frontal lobe epilepsy and children with idiopathic generalised epilepsy are at risk of Theory of Mind (ToM) deficits. ToM refers to social cognitive skills, including the ability to understand the thoughts, intentions, beliefs, and emotions of others. It has been proffered that ToM deficits may contribute to the feelings of stigma experienced by PWE. In this study we tested this for the first time...

Through the use of operant conditioning, the authors developed a technique to facilitate obtaining blood samples from a black rhinoceros diagnosed with idiopathic epilepsy. The technique involved operant conditioning to facilitate venipuncture of the transverse facial vein, at an anatomic landmark on the lateral side of the face ventral to the medial canthus of the eye, and dorsal to the lateral commissure of the mouth. The investigators used standard operant conditioning protocols to train the animal for desensitization to a needle puncture in the facial vein...

Atypical benign partial epilepsy (ABPE) of childhood or pseudo-Lennox syndrome is a form of idiopathic focal epilepsy characterized by multiple seizure types, focal and/or generalized epileptiform discharges, continuous spike-wave during sleep (CSWS), and sometimes reversible neurocognitive deficits. There are few reported cases of ABPE describing detailed correlative longitudinal follow-up of the various associated neurocognitive, language, social communicative, or motor deficits, in parallel with the epilepsy...

Sultiame is recommended for the treatment of benign epilepsy of childhood with centrotemporal spikes, electrical status epilepticus during slow-wave sleep, as well as other genetic (idiopathic) focal epilepsies. Sultiame is not traditionally considered a treatment choice for idiopathic generalised epilepsy, and it does not appear on the list of drugs recommended for treatment of absence seizures. We report the efficacy of sultiame in treating three children with drug-resistant absence seizures and discuss the potential use of sultiame beyond the idiopathic focal epilepsies...

Epilepsy is one of the most common serious neurologic conditions. It is characterized by the tendency to have recurrent seizures, which arise against a backdrop of apparently normal brain activity. At present, clinical diagnosis relies on the following: (1) case history, which can be unreliable; (2) observation of transient abnormal activity during electroencephalography (EEG), which may not be present during clinical evaluation; and (3) if diagnostic uncertainty occurs, undertaking prolonged monitoring in an attempt to observe EEG abnormalities, which is costly...

Idiopathic trigeminal neuralgia (TN) is a debilitating pain disorder characterized by episodic unilateral facial pain along the territory of branches of the trigeminal nerve. Human painful disorders, but not TN, have been linked to gain-of-function mutations in peripheral voltage-gated sodium channels (NaV1.7, NaV1.8 and NaV1.9). Gain-of-function mutations in NaV1.6, which is expressed in myelinated and unmyelinated CNS and peripheral nervous system neurons and supports neuronal high-frequency firing, have been linked to epilepsy but not to pain...

INTRODUCTION: "Common epilepsies", merely explored for genetics are the most frequent, nonfamilial, sporadic cases in hospitals. Because of their much debated molecular pathology, there is a need to focus on other neuronal pathways including the existing ion channels. METHODS: For this study, a total of 214 epilepsy cases of North Indian ethnicity comprising 59.81% generalized, 40.19% focal seizures, and based on epilepsy types, 17.29% idiopathic, 37.38% cryptogenic, and 45...

OBJECTIVE: The objective of this study was to identify cognitive phenotypes in children with new-onset focal and generalized idiopathic epilepsies and determine their relationship with epilepsy syndrome, brain structure, neurodevelopmental history, and family characteristics. METHODS: One hundred thirty-eight children with new-onset epilepsy and 95 controls (age: 8-18) underwent neuropsychological, clinical, and quantitative MR evaluations. Control participants' neuropsychological data were subjected to confirmatory factor analysis and then resultant factor scores were applied to participants with epilepsy and subjected to latent class analysis...

Perampanel (PER) is the first-in-class selective, noncompetitive α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor antagonist that has been licensed and marketed as antiepileptic drug (AED) indicated for patients with partial-onset and primary generalized tonic-clonic seizures. A positive effect was reported in some patients with epileptic myoclonic jerks in idiopathic generalized epilepsy and in progressive myoclonic epilepsy. We treated a male patient with posthypoxic nonepileptic myoclonus (Lance-Adams syndrome) with add-on PER and achieved an almost complete cessation of jerks...
