PURPOSE: Activation of CB1 receptors, produces anticonvulsant effect accompanied by memory disturbance both in animal seizure tests and in patients with epilepsy. Few reports considered the role of CB2 receptor on seizure susceptibility and cognitive functions. The aim of the present study was to explore the effect of a selective CB2 receptor agonist β-caryophyllene (BCP) in models of seizures and cognition in mice. METHODS: Dose-dependent effects of BCP was studied in maximal electroshock seizure (MES) test, subcutaneous pentylenetetrazole (scPTZ) test and Morris water maze test...

The aim of this review is to evaluate whether open-loop or closed-loop neocortical electrical stimulation should be the preferred approach to manage seizures in intractable epilepsy. Twenty cases of open-loop neocortical stimulation with an implanted device have been reported, in 5 case studies. Closed-loop stimulation with an implanted device has been investigated in a larger number of patients in the RNS System clinical trials. With 230 patients enrolled at the start of the Long-term Treatment Trial, 115 remained at the last reported follow-up...

Metabotropic glutamate (mGlu) receptors are expressed in key regions of the cortex and the thalamus and are known to regulate spike and wave discharges (SWDs), the electroclinical hallmarks of absence seizures. Recent preclinical studies have highlighted the therapeutic potential of selective group I and III mGlu receptor subtype allosteric modulators, which can suppress pathological SWDs. Of particular interest are positive allosteric modulators (PAMs) for mGlu5 receptors, as they currently show the most promise as novel anti-absence epilepsy drugs...

Background: Low protein amounts are used in ketogenic diets (KDs), where an essential (indispensable) amino acid (IAA) can become limiting. Because the chemically sensitive, seizurogenic, anterior piriform cortex (APC) is excited by IAA limitation, an imbalanced KD could exacerbate seizure activity. Objective: We questioned whether dietary IAA depletion worsens seizure activity in rodents fed KDs. Methods: In a series of 6 trials, male rats or gerbils of both sexes (6-8/group) were given either control diets (CDs) appropriate for each trial, a KD, or a threonine-devoid (ThrDev) diet for ≥7 d, and tested for seizures using various stimuli...

Metabolic epilepsy is a metabolic abnormality which is associated with an increased risk of epilepsy development in affected individuals. Commonly used antiepileptic drugs are typically ineffective against metabolic epilepsy as they do not address its root cause. Presently, there is no review available which summarizes all the treatment options for metabolic epilepsy. Thus, we systematically reviewed literature which reported on the treatment, therapy and management of metabolic epilepsy from four databases, namely PubMed, Springer, Scopus and ScienceDirect...

The International League Against Epilepsy has recently published a new classification of epileptic seizures and epilepsies to reflect the major scientific advances in our understanding of the epilepsies since the last formal classification 28 years ago. The classification emphasises the importance of aetiology, which allows the optimisation of management. Antiepileptic drugs (AEDs) are the main approach to epilepsy treatment and achieve seizure freedom in about two-thirds of patients. More than 15 second generation AEDs have been introduced since the 1990s, expanding opportunities to tailor treatment for each patient...

INTRODUCTION: The ketogenic diet is a non-pharmacological treatment that has been used as a therapeutic alternative for the management of refractory epilepsy since 1921. It is a diet, high in fats and low in carbohydrates, which is used to treat paediatric refractory epilepsy, and is effective in around 50% of the patients that begin to follow it. It is a nutrition plan that is imbalanced in terms of both macro- and micro-nutrients, which can give rise to nutritional deficits in energy, proteins, minerals and vitamins, as well as an excess of lipids...

Ketogenic diet (KD) has for a long time been known as an effective treatment for medically intractable epilepsy. However, the underlying mechanism is still unknown. Recent work indicates, that several mechanisms exist for KD, including neurotransmitter regulation, glucose restriction, effects of fatty acids, altered mitochondrial function and mammalian target of rapamycin pathway. Revealing the mechanisms of KD provides a better insight in the pathophysiology of epilepsy and helps the development of new treatments of epilepsy and other neurological disorders...

Paullinia cupana-containing preparations are being consumed worldwide for weight reduction. As obesity and epilepsy are common comorbidities and lamotrigine (LTG) is a broad-spectrum antiepileptic drug, it is likely to find epilepsy patients taking P. cupana and LTG simultaneously. Thus, this work aimed to investigate the potential interaction between P. cupana extract and LTG in rats. In a study, rats were orally co-administered with a single-dose of P. cupana extract (821 mg/kg) and LTG (10 mg/kg). In another study, rats were orally pre-treated for 14 days with P...

The neurosurgical treatment of skull base temporal encephalocele for patients with epilepsy is variable. We describe two adult cases of temporal lobe epilepsy (TLE) with spheno-temporal encephalocele, currently seizure-free for more than two years after anterior temporal lobectomy (ATL) and lesionectomy sparing the hippocampus without long-term intracranial electroencephalogram (EEG) monitoring. Encephaloceles were detected by magnetic resonance imaging (MRI) and confirmed by maxillofacial head computed tomography (CT) scans...

Neurosurgery is an under-utilised treatment that can potentially cure drug-refractory epilepsy. Careful, multidisciplinary pre-surgical evaluation is vital for selecting patients and ensure optimal outcomes. Advances in neuroimaging have improved diagnosis and guide surgical intervention. Invasive electroencephalography allows the evaluation of complex patients who would otherwise not be candidates for neurosurgery. We review the current state of the assessment and selection of patients and consider established and novel surgical procedures, and associated outcome data...
