The number of patients who suffer from symptomatic partial epilepsy is significant, and those who undergo neurosurgery often experience refractory seizures. Levetiracetam (LEV) is a new-generation anti epileptic drug (AED). Previous studies have shown that LEV has favorable efficacy and a good safety profile with few drug interactions, as it has a unique pharmacological mechanism and acts on synaptic vesicle protein. This study aimed at estimate the efficacy and safety of 1,000 to 2,000 mg/day of LEV as an add-on therapy for refractory symptomatic seizures treated in the department of neurosurgery of our hospital...

PURPOSE: Perampanel (PER) and lacosamide (LCM) are antiepileptic drugs (AEDs) approved for the adjunctive treatment of partial-onset seizures. At the time of market entry, information on clinical effectiveness of new AEDs is limited to results from pivotal trials, real-life or comparative data are missing. This analysis of data collected retrospectively in a German epilepsy center used unified evaluation criteria, and describes treatment outcomes with LCM and PER at 6 months. METHODS: Results of the first 70 consecutive patients who had received LCM or PER after their market entries in Germany were compared...

Vision is a very important sensory modality in humans. Visual disorders are numerous and arising from diverse and complex causes. Deficits in visual function are highly disabling from a social point of view and in addition cause a considerable economic burden. For all these reasons there is an intense effort by the scientific community to gather knowledge on visual deficit mechanisms and to find possible new strategies for recovery and treatment. In this review, we focus on an important and sometimes neglected player of the visual function, the corpus callosum (CC)...

In addition to visual analysis digital computerized recording of electrical and magnetic fields by using EEG and MEG opened a new window for research concerning improved understanding of pathophysiology, diagnosis and treatment of epilepsies. In the last 25 years MEG was used more and more in clinical studies concerning localization of focal epileptic activity, functional cortex and network analysis. Simultaneous MEG/EEG recording and analysis offer the use of complimentary information increasing the sensitivity for tracing primary epileptic activity...

There has been considerable debate surrounding the benefits and drawbacks of the new approach to classifying the epilepsies released by the ILAE Commission on Classification and Terminology (2005-2009). This new approach has significant implications for the way we conceptualize and assess cognition and behavior in epilepsy; however, as yet, there has been limited discussion of these issues in the field. The purpose of this Targeted Review is to spark this discussion by encouraging researchers and clinicians to think about the changes that the new approach may bring...

About 30% of the patients with epilepsy do not respond to clinically established anticonvulsants, despite having effective concentrations of the antiepileptic drug in plasma. Therefore, new preclinical models of epilepsy are needed to identify more efficacious treatments. We describe here a new drug-resistant seizure model in mice to be used at the early stages of pre-clinical trials. This model consists in inducing daily generalized seizures for 23 consecutive days by administration of 3-mercaptopropionic acid (MP)...

Rapid developments in molecular genetic technology and research have swiftly advanced our understanding of neuro-oncology. As a consequence, the WHO invited their expert panels to revise the current classification system of brain tumours and to introduce, for the first time, a molecular genetic approach for selected tumour entities, thus setting a new gold standard in histopathology. The revised 5th edition of the 'blue book' was released in May 2016 and will have a major impact in stratifying diagnosis and treatment...

Development of the nervous system requires a variety of cellular activities, such as proliferation, migration, axonal outgrowth and guidance and synapse formation during the differentiation of neural precursors into mature neurons. Malfunction of these highly regulated and coordinated events results in various neurological diseases. The Elongator complex is a multi-subunit complex highly conserved in eukaryotes whose function has been implicated in the majority of cellular activities underlying neurodevelopment...

The hippocampus is prone to epileptic seizures and is a key brain region and experimental platform for investigating mechanisms associated with the abnormal neuronal excitability that characterizes a seizure. Accordingly, the hippocampal slice is a common in vitro model to study treatments that may prevent or reduce seizure activity. The ketogenic diet is a metabolic therapy used to treat epilepsy in adults and children for nearly 100 years; it can reduce or eliminate even severe or refractory seizures. New insights into its underlying mechanisms have been revealed by diverse types of electrophysiological recordings in hippocampal slices...

Despite the development of new antiepileptic drugs (AEDs), ~20%-30% of people with epilepsy remain refractory to treatment and are said to have drug-resistant epilepsy (DRE). This multifaceted condition comprises intractable seizures, neurobiochemical changes, cognitive decline, and psychosocial dysfunction. An ongoing challenge to both researchers and clinicians alike, DRE management is complicated by the heterogeneity among this patient group. The underlying mechanism of DRE is not completely understood. Many hypotheses exist, and relate to both the intrinsic characteristics of the particular epilepsy (associated syndrome/lesion, initial response to AED, and the number and type of seizures prior to diagnosis) and other pharmacological mechanisms of resistance...

Cyclic vomiting syndrome (CVS) is an uncommon, idiopathic disorder defined by recurrent, sudden-onset attacks of repetitive retching and vomiting that are separated by symptom-free intervals. CVS was long regarded as a disorder primarily experienced by children but is now known to present de novo in adulthood. Adult CVS has garnered more research attention over the past 20 years, and these efforts have identified some acute and prophylactic treatments for this disorder. However, CVS still lacks a unifying disease model, and this has hindered the development of new therapies...

Therapy with current antiepileptic drugs aims at reducing the likelihood of seizure occurrence rather than influencing the underlying disease process. Therefore, antiepileptic drugs have an anticonvulsant rather than antiepileptic property. Areas covered: The increasing identification of genetic causes for epilepsy over the recent years improves the understanding of the underlying epileptogenic process and allows for the possibility of directed therapeutic approaches. An ideal antiepileptic therapy consists of a drug which is able to influence the functional changes caused by a specific pathogenic variant...

Several newer antiepileptic drugs (AEDs) have been introduced into clinical practice, offering choices for individualizing the treatment of epilepsy since AEDs have different efficacy and tolerability profiles. In particular, questions exist regarding which AEDs are the best options for the monotherapy of focal epilepsy. Is carbamazepine (CBZ), which is considered the standard treatment for focal epilepsy, still the best option for monotherapy of focal epilepsy, despite the emergence of new AEDs? In this systematic review, we compared the relative tolerability of all available AEDs for monotherapy of all types of epilepsy as well as their efficacy in the monotherapy of focal epilepsy...

Preclinical Research Epilepsy is a chronic devastating neurological disorder characterized by synchronous interictal discharges. Treatment with antiepileptic drugs (AEDs) can alleviate spontaneous seizure activity without preventing the progression and development of epileptogenesis. Current design and development of new AEDs and strategies for the prevention of epilepsy is focused mainly on attenuating uncontrolled seizures, severe side effects and toxicity in chronic drug therapy. It has thus become necessary to discover new chemical pharmacophores with a broad spectrum of activity and less neurotoxicity...

A 40-year-old man presented with a series of generalized tonic-clonic seizures after febrile illness. He developed status epilepticus and required mechanical ventilation with anesthetics. Steroid pulse, intravenous immunoglobulin, and immunoadsorption therapy were administrated, and the status epilepticus improved; however, drug-resistant seizures remained. Despite the use of several antiepileptic drugs, seizures frequently occurred. Additional administration of potassium bromide resulted in significant suppression of seizures...
