Animal models are valuable tools for screening novel therapies for patients who suffer from epilepsy. However, a wide array of models are necessary to cover the diversity of human epilepsies. In humans, neonatal hypoxia (or hypoxia-ischemia) is one of the most common causes of epilepsy early in life. Hypoxia-induced seizures (HS) during the neonatal period can also lead to spontaneous seizures in adulthood. This phenomenon, i.e., early-life hypoxia leading to adult epilepsy - is also seen in experimental models, including rats...

High and increasing prevalence of neurodevelopmental disorders place enormous personal and economic burdens on society. Given the growing realization that the roots of neurodevelopmental disorders often lie in early childhood, there is an urgent need to identify childhood risk factors. Neurodevelopment is marked by periods of heightened experience-dependent neuroplasticity wherein neural circuitry is optimized by the environment. If these critical periods are disrupted, development of normal brain function can be permanently altered, leading to neurodevelopmental disorders...

OBJECTIVES: Depression is common in epilepsy, with rates ranging from 20 to 55% in most samples and reports as high as 70% in patients with intractable epilepsy. However, some contend that depression may be over- and/or under-reported and treated in this population. This may be due to the use of common self-report depression measures that fail to take into account the overlap of disease and depressive symptoms and also the host of side effects associated with antiepileptic medication, which may also be construed as depression...

Very recently, neuromodulation through deep brain stimulation (DBS) has appeared as a new surgical procedure in the treatment of some types of dementia and epilepsy. The mammillothalamic and the mammillotegmental tracts are involved among the new targets. To our knowledge, a review article focused specifically on these mammillary body efferents is lacking in the medical literature. Their contribution to memory is, regrettably, often overlooked. There is evidence that mammillary bodies can contribute to memory independently from hippocampal formation, but the mechanism is not yet known...

Stereotactic laser ablation of mesial temporal structures is a promising new surgical intervention for patients with mesial temporal lobe epilepsy (MTLE). Since this procedure was first used to treat MTLE in 2010, the literature contains reports of 37 patients that underwent MR-guided stereotactic laser amygdalohippocampotomy (SLAH) using Laser Interstitial Thermal Therapy (LITT) with at least 1year of follow-up. This early body of data suggests that SLAH is a safe and effective treatment for MTLE in properly selected patients...

BACKGROUND: Epilepsy is a common condition with up to 1% prevalence in the general population. In the perioperative course of neurologic surgery patients, the use of prophylactic and therapeutic antiepileptic drugs is a common practice. Nonetheless, there is limited evidence supporting the use of prophylactic antiepileptics to prevent perioperative seizures and there are no guidelines for which anesthetic technique is preferred. OBJECTIVE: To discuss the seizurogenic potential of anesthetic drugs and to discuss intraoperative seizures in neurosurgical patients...

BACKGROUND: Temporal lobe epilepsy is the second most common neurological disorders characterized by recurrent spontaneous seizures. MicroRNAs play a vital role in regulating synaptic plasticity, brain development and post-transcriptional expression of proteins. In both animal models of epilepsy and human patients, miR-134, a brain-specific microRNA has recently been identified as a potential regulator of epileptogenesis. METHODS: microRNA identified as targets for the actions of valproic acid (VPA) are known to have important effects in brain function...

BACKGROUND: The contribution of genetic factors to epilepsy has long been recognized and has been estimated to play a role in 70% to 80% of cases. Identification of a pathogenic variant can help families to better cope with the disorder, allows for genetic counseling to determine recurrence risk, and in some cases, can directly influence treatment options. In this study, we determined the diagnostic yield of a clinical gene panel applied to an unselected cohort of epilepsy patients. METHODS: Variant reports from 339 clinically referred epilepsy patients screened using a 110-gene panel were retrospectively reviewed...

Schwannomas originating from the olfactory nerve are extremely rare because the olfactory nerve does not normally contain Schwann cells. We describe a case of a giant schwannoma of the olfactory groove. A 73-year-old woman presented with anosmia persisting for 10 months. Head computed tomography(CT)for head trauma at another hospital demonstrated a tumor lesion located in the left frontal lobe and paranasal sinus. She had never suffered epilepsy, and past medical history and family history identified no indicators...

Epilepsy is a common nervous system disease. It has been found that the pathogenesis of epilepsy is associated mutations in various genes, including genes encoding voltage-dependent ion channel, genes encoding ligand-gated ion channel, and solute carrier family genes. Different types of epilepsy caused by different mutations have different responses to drugs, and therefore, diagnosis and medication guidance based on genes are new thoughts for developing therapies. With the application of next-generation sequencing technology, more and more genes will be determined, which helps to further study the pathogenic mechanism of mutant genes and provides a basis for precision drug therapy for epilepsy...

Riki Matsumoto, Mitsuhiro Sakamoto, Akio Ikeda
The recent discovery of autoimmune antibodies to the neuronal cell surface membrane and extra- or intra-cellular proteins, such as NMDAR and LGI1, shed light on a proposed new etiology of epilepsy, namely, "autoimmune epilepsy". A large part of this entity most likely belongs to a forme fruste of autoimmune (limbic) encephalitis. Seizures are usually subacute in onset and refractory to antiepileptic medications. Patients occasionally manifest multiple seizure semiologies, such as autonomic or faciobrachial dystonic seizures...

In Japan, the Road Traffic Act was amended in 2013, and the revision was enacted in 2014. This revision includes new rules such as the requirement that a driver declare medical conditions on licensing, with a penalty for false statements. There is also a new voluntary notification system that enables doctors to report unlawful drivers. At the same time, the new Criminal Law Act was enacted. This act provides a penalty for causing death or injury to other persons by driving under the influence of specific drugs or diseases, including epilepsy...

Early hospital readmission has become a proxy for quality of care and contributes significantly to high health care costs in the United States, with more than $20 billion health care dollars are spent on 30-day readmission annually. Cranial neurosurgical procedures (i.e., craniotomy, craniectomy) are associated with high readmission rates; however, studies examining readmission after cranial procedures are limited and relatively unknown. The aim of this study is to identify the drivers of 30-day unplanned readmission in consecutive patients undergoing craniotomies and craniectomies...

The World Health Organisation has pointed that a successful health care delivery, requires effective medical devices as tools for prevention, diagnosis, treatment and rehabilitation. Several studies have concluded that longer monitoring periods and outpatient settings might increase diagnosis accuracy and success rate of treatment selection. The long-term monitoring of epileptic patients through electroencephalography (EEG) has been considered a powerful tool to improve the diagnosis, disease classification, and treatment of patients with such condition...

BACKGROUND: An increasing amount of evidence suggests an association between epilepsy and multiple somatic and psychiatric conditions, which is more significant than in the general population. Furthermore, a bidirectional association has been established between epilepsy and several conditions, notably depression and suicide, cerebrovascular disease, stroke, dementia and migraine, which is best explained by the presence of common underlying mechanisms and risk factors. Gaining knowledge about these common mechanisms can provide insight into new therapeutic targets, screening and preventive measures...

REVIEW
David Gloss, Sarah J Nevitt, Richard Staba
BACKGROUND: Epilepsy is a serious brain disorder characterized by recurrent unprovoked seizures. Approximately two-thirds of seizures can be controlled with antiepileptic medications (Kwan 2000). For some of the others, surgery can completely eliminate or significantly reduce the occurrence of disabling seizures. Localization of epileptogenic areas for resective surgery is far from perfect, and new tools are being investigated to more accurately localize the epileptogenic zone (the zone of the brain where the seizures begin) and improve the likelihood of freedom from postsurgical seizures...
