Epilepsy affects people in all ages with the highest incidence in small children, particularly before age one year, and in elderly aged 65 years and older. In Sweden, between 4500-5000 persons develop epilepsy annually. Based on studies from North America and Europe, including the Nordic countries, the number of people with active epilepsy in Sweden is between 60000-70000. The lifetime risk for epilepsy up to age 85 years is 4-5 %, i.e. approximately every 25th person. The new epilepsy classification divides etiology into the following groups: structural, genetic, infectious, metabolic, immune and unknown...

BACKGROUND: There were several studies that have reported on the long-term mortality rate of status epilepticus (SE). However, these studies were conducted mainly in Western countries using small study populations. This study aimed to evaluate predictors for long-term mortality in SE using the Thai national healthcare database. METHODS: This study was conducted using the Thai national Universal Health Coverage (UC) database. The eligibility criteria for this study were that all patients were diagnosed with SE and had been admitted to any hospital between 2005 and 2015...

Abnormal dendritic sprouting and synaptic remodelling are important pathological features of temporal lobe epilepsy. BC1 RNA is a translation repressor involved in the regulation of the dendritic protein synthesis and mRNA transport, which is essential for dendritic development and plasticity. The expression alteration of BC1 RNA in the pilocarpine induced epilepsy model remains unknown. It is unclear if the interactions between BC1 RNA and eukaryotic initiation factor 4A (eIF4A) exists in this model. The purpose of this study was to investigate the expression changes of BC1 RNA and its interactions with eIF4A post-status epilepticus (SE)...

Christianson syndrome (CS) is a recently described rare neurogenetic disorder presenting early in life with a broad range of neurological symptoms, including severe intellectual disability with nonverbal status, hyperactivity, epilepsy, and progressive ataxia due to cerebellar atrophy. CS is due to loss-of-function mutations in SLC9A6, encoding NHE6, a sodium-hydrogen exchanger involved in the regulation of early endosomal pH. Here we review what is currently known about the neuropathogenesis of CS, based on insights from experimental models, which to date have focused on mechanisms that affect the CNS, specifically the brain...

The efficacy of benzodiazepines to terminate electrographic status epilepticus (SE) declines the longer a patient is in SE. Therefore, alternative methods for ensuring complete block of SE and refractory SE are necessary. We compared the ability of diazepam and a subanesthetic dose of urethane to terminate prolonged SE and mitigate subsequent pathologies. Adult Sprague Dawley rats were injected with diisopropylfluorophosphate (DFP) to induce SE. Rats were administered diazepam (10 mg/kg, ip) or urethane (0...

Stereotactic radiosurgery (SRS) is a promising treatment for medically intractable mesial temporal lobe epilepsy. SRS for epilepsy has had an acceptable safety profile with reports of radiation-induced vascular malformations confined to central nervous system pathologies with prominent angiogenesis - namely, primary brain tumors, metastases, and arteriovenous malformations. Theoretical risks for radiation-induced lesions following radiosurgery for epilepsy have yet to be established. Of 13 patients treated in a pilot trial for medial temporal lobe epilepsy, one developed multiple delayed radiation-induced cavernous malformations following radiosurgery...

OBJECTIVE: We assessed how commonly prior authorization results in treatment delay or missed doses in children with epilepsy. METHODS: Parents of 462 children followed in a pediatric epilepsy clinic were surveyed regarding prior authorization in the preceding year. Epilepsy and insurance details were collected. If prior authorization was required, parents were asked whether it resulted in (1) delayed initiation of a newly-prescribed antiepileptic drug, and/or (2) lapse in coverage of a current medication...

BACKGROUND: New-onset refractory status epilepticus (NORSE) refers to a clinical presentation in a patient without active epilepsy or other existing relevant neurological disorder, with new onset of refractory status epilepticus in the absence of a clear acute or active structural, metabolic, or toxic cause. Febrile infection-related epilepsy syndrome (FIRES) is a subset of NORSE that requires a febrile infection between 24 hours and 2 weeks prior to the onset of refractory status epilepticus, with or without fever at the onset of status epilepticus, and with no restriction to the age of the patient...

The inflammatory response mediated by microglia in the central nervous system is closely related to epilepsy. Notch signaling plays an important role in the microglial activation during hypoxia. This study aimed to investigate whether Notch signaling is involved in microglial activation and subsequent inflammation-related neuronal injury during the process of epileptogenesis in a rat model of temporal lobe epilepsy. By using western blotting, real-time quantitative PCR, immunohistochemistry and immunofluorescence labeling, we found that the expression of Notch signaling increased after status epilepticus and that a γ-secretase inhibitor could significantly inhibit the upregulation of Notch signaling, the activation of microglia, and the release of proinflammatory cytokines...

BACKGROUND: Catamenial epilepsy refers to cyclic seizure exacerbation in relation to the menstrual cycle. Three distinct patterns have been described: C1-perimenstrual, C2-periovulatory, and C3-inadequate luteal. There is experimental and clinical evidence that gonadal steroid hormones affect neuronal excitability with estrogens being mainly proconvulsant and progesterone anticonvulsant. If reproductive steroids have a role in seizure occurrence, they may also have a role in treatment...
