BACKGROUND: Previous studies suggest that changing patients' anti-epileptic drug regimen can reduce the frequency of seizures. The approval of new anti-epileptic drugs with different modes of action during the last decades has provided multiple options for the treatment of epilepsy, although the efficacy of these new drugs is controversial. We aimed to determine the effects of adding or changing to a previously untried anti-epileptic drug, including recently approved drugs, on the frequency of seizures in patients with drug-resistant epilepsy...

Tuberous Sclerosis Complex (TSC) is a rare genetic disorder that results from a mutation in the TSC1 or TSC2 genes leading to constitutive activation of the mechanistic target of rapamycin complex 1 (mTORC1). TSC is associated with autism, intellectual disability and severe epilepsy. Cortical tubers are believed to represent the neuropathological substrates of these disabling manifestations in TSC. In the presented study we used high-throughput RNA sequencing in combination with systems-based computational approaches to investigate the complexity of the TSC molecular network...

OBJECTIVE: There are no evidence-based guidelines on the preferred approach to treating early-life epilepsy. We examined initial therapy selection in a contemporary US cohort of children with newly diagnosed, nonsyndromic, early-life epilepsy (onset before age three years). METHODS: Seventeen pediatric epilepsy centers participated in a prospective cohort study of children with newly diagnosed epilepsy with onset under 36 months of age. Details regarding demographics, seizure types, and initial medication selections were obtained from medical records...

First part of this review (Chapter 1) demonstrates an ambiguous attitude toward psychiatry among professionals and in society in recent decades. The articles of supporters and opponents of psychiatry are also quoted. The authors describe the dynamics of the reflection of psychopathology in the main widely accepted classifications and manuals. Critical and negative opinions regarding the DSM-5, due to its role in the 'medicalization' processes, for the movement 'World Mental Health', are mentioned. The history of antipsychiatry movement and its results for psychiatry and society are analyzed as well...

In recent years, the source localization technique of magnetoencephalography (MEG) has played a prominent role in cognitive neuroscience and in the diagnosis and treatment of neurological and psychological disorders. However, locating deep brain activities such as in the mesial temporal structures, especially in preoperative evaluation of epilepsy patients, may be more challenging. In this work we have proposed a modified beamforming approach for finding deep sources. First, an iterative spatiotemporal signal decomposition was employed for reconstructing the sensor arrays, which could characterize the intrinsic discriminant features for interpreting sensor signals...

BACKGROUND: Animal models when carefully selected, designed and conducted, are important parts of any translational drug development strategy. However, research of new compounds for patients with drug-resistant epilepsies is still based on animal experiments, mostly in rodents, which are far from being a model of chronic human epilepsy and have failed to differentiate the efficacy of new compounds versus standard drug treatment. Objective The objective was identification and description of compounds in clinical development in 2016...

BACKGROUND: A variety of evidence suggested that an imbalance in excitatory and inhibitory neurotransmission could be one of the pathophysiological mechanisms underlying the occurrence and progression of seizures. Understanding the causes of this imbalance may provide essential insight into the basic mechanisms of epilepsy and may uncover novel targets for future drug therapies. Accordingly, GABA is the most important inhibitory neurotransmitter in the CNS and its receptors (e.g., GABAARs) can still be relevant targets of new antiepileptic drugs (AEDs)...

BACKGROUND: Epileptic encephalopathies represent the most severe epilepsies, with onset in infancy and childhood and seizures continuing in adulthood in most cases. New genetic causes are being identified at a rapid rate. Treatment is challenging and the overall outcome remains poor. Available targeted treatments, based on the precision medicine approach, are currently few. OBJECTIVE: To provide an overview of the treatment of epileptic encephalopathies with known genetic determinants, including established treatment, anecdotal reports of specific treatment, and potential tailored precision medicine strategies...

BACKGROUND: Despite the introduction of new antiepileptic drugs (AEDs), the quality of life and therapeutic response for patients with epilepsy remain unsatisfactory. In addition, whilst several antiepileptic drugs (AEDs) have been approved and consequently marketed in recent years, little is known about their long-term safety and tolerability. Availability of the newest AEDs, characterized by improved pharmacokinetic profiles, has positively impacted the treatment approach for patients with partial seizures in clinical practice...

Patrick A Forcelli
Epilepsy is the quintessential circuit disorder, with seizure activity propagating through anatomically constrained pathways. These pathways, necessary for normal sensory, motor, and cognitive function, are hijacked during seizures. Understanding the network architecture at the level of both local microcircuits and distributed macrocircuits may provide new therapeutic avenues for the treatment of epilepsy. Over the past decade, optogenetic and chemogenetic tools have enabled previously impossible levels of functional circuit mapping in neuroscience...

Treatment of TBI remains a major unmet medical need, with 2.5 million new cases of traumatic brain injury (TBI) each year in Europe and 1.5 million in the USA. This single-center proof-of-concept preclinical study tested the hypothesis that pharmacologic neurostimulation with proconvulsants, either atipamezole, a selective α2-adrenoceptor antagonist, or the cannabinoid receptor 1 antagonist SR141716A, as monotherapy would improve functional recovery after TBI. A total of 404 adult Sprague-Dawley male rats were randomized into two groups: sham-injured or lateral fluid-percussion-induced TBI...

BACKGROUND & OBJECTIVES: Although the need for a combination of antiepileptic drugs (AEDs) in the treatment of epilepsy is well justified, but an associated increase in adverse effects (AEs) lends a restriction to polytherapy. The aim of this study was to evaluate AEs and drug load (prescribed daily dose/defined daily doses) of AEDs in patients with epilepsy (PWE). METHODS: Consecutive PWEs attending Epilepsy clinic in a tertiary care hospital in New Delhi, India, were enrolled in the study...

REVIEW
Graciana L Galiana, Angela C Gauthier, Richard H Mattson
Eslicarbazepine acetate is a new anti-epileptic drug belonging to the dibenzazepine carboxamide family that is currently approved as adjunctive therapy and monotherapy for partial-onset (focal) seizures. The drug enhances slow inactivation of voltage-gated sodium channels and subsequently reduces the activity of rapidly firing neurons. Eslicarbazepine acetate has few, but some, drug-drug interactions. It is a weak enzyme inducer and it inhibits cytochrome P450 2C19, but it affects a smaller assortment of enzymes than carbamazepine...

Background: Lennox-Gastaut syndrome (LGS) is a severe form of childhood-onset epilepsy associated with serious injuries due to frequent and severe seizures. Of the antiepileptic drugs (AEDs) approved for LGS, clobazam is a more recent market entrant, having been approved in October 2011. Recent AED budget impact and cost-effectiveness analyses for LGS suggest that adding clobazam to a health plan formulary may result in decreased medical costs; however, research on clinical and economic outcomes and treatment patterns with these AED treatments in LGS is limited...

INTRODUCTION: Deep Brain Stimulation (DBS) is an effective treatment extended broadly to many neurological and psychiatric disorders. Nevertheless, complications may arise during DBS procedures or following implantation due to implanted hardware. This may result in both minor and major adverse events that may necessitate hardware removal and/or compromise maximal therapeutic benefit for the patient. OBJECTIVES AND METHODS: To identify relevant literature on hardware-related complications from DBS procedures by performing a systematic review, and propose how to identify at-risk group and possible preventive approaches...

High prevalence of therapy-resistant epilepsy demands development of anticonvulsants with new mechanisms of action. Brivaracetam is an analogue of levetiracetam which binds to the synaptic vesicle protein 2A (SV2A) and decreases release of excitatory neurotransmitters. Areas covered: Relevant published studies were searched for by predefined strategy in MEDLINE, EBSCO and SCINDEKS electronic databases. Brivaracetam is effective as adjunctive therapy for uncontrolled partial-onset seizures with or without secondary generalization in patients 16 years and older with epilepsy...

Occipital lobe epilepsy of childhood includes two entities: Panayiotopoulos syndrome in pre-school children, and idiopathic childhood occipital epilepsy of Gastaut (ICOEG) in school-age children. The typical initial manifestation of the former is vomiting, and that of the latter is visual hallucinations. Ictal cardiopulmonary arrest at initial presentation has been reported for Panayiotopoulos syndrome, but not for ICOEG. We document a 7-year-old previously healthy girl who experienced an acute elemental visual hallucination of seeing insects, followed by a new-onset generalized seizure...

OBJECTIVE: ATP is released into the extracellular space during pathologic processes including increased neuronal firing. Once released, ATP acts on P2 receptors including ionotropic P2X and metabotropic P2Y receptors, resulting in changes to glial function and neuronal network excitability. Evidence suggests an involvement of P2Y receptors in the pathogenesis of epilepsy, but there has been no systematic effort to characterize the expression and function of the P2Y receptor family during seizures and in experimental and human epilepsy...
