Epilepsy is a chronic brain syndrome characterized by recurrent seizures resulting from excessive neuronal discharges. Despite the development of various new antiepileptic drugs, many patients are refractory to treatment and report side effects. Non-invasive methods of brain stimulation, such as transcranial direct current stimulation (tDCS), have been tested as alternative approaches to directly modulate the excitability of epileptogenic neural circuits. Although some pilot and initial clinical studies have shown positive results, there is still uncertainty regarding the next steps of investigation in this field...

PURPOSE: Polymicrogyria, a malformation of the cerebral cortex, frequently causes epilepsy. Diffuse bilateral polymicrogyria (DBP) is related to poor epilepsy prognosis, but most patients with DBP are not good candidates for resective epilepsy surgery and effectiveness of corpus callosotomy (CC), a palliative surgery, for patients without resective epileptogenic cortices, has not been established in DBP. Because CC might be effective against DBP-related epilepsy, we conducted total CC in three pediatric DBP cases...

BACKGROUND AND PURPOSE: A non-psychoactive phytocannabinoid, cannabidiol (CBD), shows promising results as an effective potential antiepileptic drug in some forms of refractory epilepsy. In an attempt to understand the mechanisms by which CBD exerts its anti-seizure effects, we investigated the effects of CBD at synaptic connections, and the intrinsic membrane properties of hippocampal CA1 pyramidal cells and two major inhibitory interneurons: fast spiking, parvalbumin -expressing (PV) and adapting, cholecystokinin-expressing (CCK) interneurons...

Epileptic seizures are an important cause of morbidity in glioma patients. Substantial lines of evidence support the concept of the excitatory neurotransmitter glutamate being a crucial mediator of glioma-associated seizures. In gliomas, non-vesicular secretion of glutamate via the cystine-glutamate exchanger (SLC7A11, xCT) constitutes the main mechanism contributing to high extracellular glutamate concentrations. However, a convincing "proof-of-relevance" of this mechanism in patient material is lacking. A cohort of 229 consecutive patients with newly diagnosed glioma was analyzed with respect to presence, time course, and severity of epileptic seizures...

INTRODUCTION AND OBJECTIVES: Cognitive impairment is a significant comorbidity of temporal lobe epilepsy that is associated with extensive hippocampal cell loss. Deep brain stimulation (DBS) of the anterior thalamic nucleus (ANT) has been used for the treatment of refractory partial seizures. In the pilocarpine model of epilepsy, ANT DBS applied during status epilepticus (SE) reduces hippocampal inflammation and apoptosis. When given to chronic epileptic animals it reduces hippocampal excitability and seizure frequency...

Febrile infection-related epilepsy syndrome (FIRES) is a catastrophic epileptic syndrome that strikes previously healthy children aged 3-15 years and has an unknown pathogenesis and few treatments. These children experience a nonspecific febrile illness that is followed by prolonged refractory status epilepticus. Although the etiology is unknown, FIRES has a biphasic presentation, with the acute phase beginning as seizure activity lasting 1-12 weeks, then followed by the chronic phase, which is characterized by refractory seizures that cluster every 2-4 weeks, and may continue to be multifocal and independent...

BACKGROUND: Although a larger number of antiepileptic drugs became available in the last decades, epilepsy remains drug-resistant in approximately a third of patients. Ketogenic diet (KD), first proposed at the beginning of the last century, is complex and has anticonvulsant effects, yet not completely understood. Over the last decades, different types of ketogenic diets (KDs) have been developed, namely classical KD and modified Atkins diet (MAD). They offer an effective alternative for children and adults with drug-resistant epilepsies...

Myoclonic status in non-progressive encephalopathy (MSNPE) is characterized by the recurrence of long-lasting atypical status epilepticus associated with attention impairment and continuous polymorphous jerks, mixed with other complex abnormal movements, in infants suffering from a non-progressive encephalopathy. The ketogenic diet (KD) has been used as an alternative to antiepileptic drugs (AEDs) for patients with refractory epileptic encephalopathies. PURPOSE: In this study we assess the efficacy and tolerability of the KD in patients with MSNPE...

A hallmark of temporal lobe epilepsy (TLE) is hippocampal neuronal demise and aberrant mossy fiber sprouting. In addition, unrestrained neuronal activity in TLE patients induces gene expression including immediate early genes (IEGs) such as Fos and Egr1.We employed the mouse pilocarpine model to analyze the transcription factor (TF) serum response factor (SRF) in epileptogenesis, seizure induced histopathology and IEG induction. SRF is a neuronal activity regulated TF stimulating IEG expression as well as nerve fiber growth and guidance...

Microglia-mediated neuroinflammation is widely associated with seizures and epilepsy. Although microglial cells are professional phagocytes, less is known about the status of this phenotype in epilepsy. Recent evidence supports that phagocytosis-associated molecules from the classical complement (C1q-C3) play novel roles in microglia-mediated synaptic pruning. Interestingly, in human and experimental epilepsy, altered mRNA levels of complement molecules were reported. Therefore, to identify a potential role for complement and microglia in the synaptodendritic pathology of epilepsy, we determined the protein levels of classical complement proteins (C1q-C3) along with other phagocytosis signaling molecules in human epilepsy...

OBJECTIVE: Temporal lobe epilepsy (TLE) is commonly associated with depression, anxiety, and cognitive impairment. Despite significant progress in our understanding of the pathophysiology of TLE, it remains the most common form of refractory epilepsy. Enriched environment (EE) has a beneficial effect in many neuropsychiatric disorders. However, the effect of EE on cognitive changes in chronic TLE has not been evaluated. Accordingly, the present study evaluated the effects of EE on chronic epilepsy-induced alterations in cognitive functions, electrophysiology, and cellular changes in the hippocampus...

Early maladaptive internalization of synaptic GABAA receptors (GABAA R) and externalization of NMDA receptors (NMDAR) may explain the time-dependent loss of potency of standard anti-epileptic drugs (AED) in refractory status epilepticus (SE). We hypothesized that correcting the effects of changes in GABAA R and NMDAR would terminate SE, even when treatment is delayed 40 minutes. SE was induced in adult Sprague-Dawley rats with a high dose of lithium and pilocarpine. The GABAA R agonist midazolam, the NMDAR antagonist ketamine and the AED valproate were injected 40 min after SE onset in combination or as monotherapy...

Susan Blades Golubovic, John H Rossmeisl
OBJECTIVE: To discuss current anticonvulsant drug options and advances in treatment of status epilepticus (SE) and to review the prognosis associated with SE. TREATMENT: When treating a patient with SE, the main goals are to halt seizure activity, prevent further seizures, identify the cause of the seizures, and manage any complications. The veterinary literature indicates that benzodiazepines are the most common class of drugs used for the initial treatment of SE...
