Over 80% of people with epilepsy live in low- to middle-income countries where epilepsy is often undiagnosed and untreated due to limited resources and poor infrastructure. In Africa, the burden of epilepsy is exacerbated by increased risk factors such as central nervous system infections, perinatal insults, and traumatic brain injury. Despite the high incidence of these etiologies, the cause of epilepsy in over 60% of African children is unknown, suggesting a possible genetic origin. Large-scale genetic and genomic research in Europe and North America has revealed new genes and variants underlying disease in a range of epilepsy phenotypes...

We evaluated a new epilepsy genetic diagnostic and counseling service covering a UK population of 3.5 million. We calculated diagnostic yield, estimated clinical impact, and surveyed referring clinicians and families. We costed alternative investigational pathways for neonatal onset epilepsy. Patients with epilepsy of unknown aetiology onset < 2 years; treatment resistant epilepsy; or familial epilepsy were referred for counseling and testing. We developed NGS panels, performing clinical interpretation with a multidisciplinary team...

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...

In patients with Long QT Syndrome (LQTS), mutations in the potassium channel KCNH2 gene increase seizure susceptibility with missense mutations involving the pore region of the gene acting as a positive predictor of seizures. Seizures are less commonly reported in patients with carboxyl (C')-terminus mutations. This case report describes a young man who presented with syncope followed by a first seizure and was found to have LQTS caused by a pathogenic carboxyl-terminus deletion/frameshifting mutation of the KCNH2 gene...

AIMS: To examine the association between statin use before and after intracranial hemorrhage (ICH) and the risk of post-stroke epilepsy (PSE). METHODS: Patients with new-onset ICH between 2004 and 2012 were identified from the Taiwan National Health Insurance Research Database. The main outcome was the occurrence of epilepsy after stroke. Multivariable Cox regression modeling was used to estimate the association between statin use and the risk of PSE, with post-stroke medication exposures being treated as time-dependent variables...

Capgras syndrome is characterized by the delusional belief that a familiar person has been replaced by a visually similar imposter or replica. Rarely, the delusional focus may be objects rather than people. Numerous etiologies have been described for Capgras to include seizures. Similarly, visual hallucinations, both simple and complex, can occur secondary to seizure activity. We present, to our knowledge, the first reported case of visual hallucinations and Capgras delusions for objects that developed secondary to new onset occipital lobe epilepsy...

Epilepsy surgery is indicated in select patients with drug-resistant focal epilepsy. Seizure freedom or significant reduction of seizure burden without risking new neurological deficits is the expected goal of epilepsy surgery. Typically, when the seizure onset zone overlaps with eloquent cortex, patients are excluded from surgery. We present a patient with drug-resistant frontal lobe epilepsy who underwent successful surgery with resection of Broca's area, primarily involving the pars triangularis (BA 45)...

Epilepsy of infancy with migrating focal seizures (EIMFS) is a rare type of early-onset epileptic encephalopathy that is characterized by refractory migratory multifocal seizures that migrate between hemispheres. Its etiology is not well known although it is postulated to occur due to channelopathy. The authors report the first case of EIMFS due to a de novo heterozygous mutation in exon 4(c.881C>T missense mutation, p.Ala294Val, NM_172107.2) in KCNQ2 gene which later evolved into infantile spasms. However, it is the second case of EIMFS with KCNQ2 mutation...

BACKGROUND: Prodromal symptoms (PS) of epileptic seizures are clinically well-recognized but relatively little researched. The purpose of this review was to examine the evidence in the literature for the existence of prodrome and the reported frequency and nature of prodromal characteristics. METHODS: We performed a PubMed review of the clinical characteristics, frequency, and duration of PS in papers published between 2007 and 2017. We also reviewed findings from prospective studies into the predictive performance of prodrome...

Between seizures, irritative network generates frequent brief synchronous activity, which manifests on the EEG as interictal epileptiform discharges (IEDs). Recent insights into the mechanism of IEDs at the microscopic level have demonstrated a high variance in the recruitment of neuronal populations generating IEDs and a high variability in the trajectories through which IEDs propagate across the brain. These phenomena represent one of the major constraints for precise characterization of network organization and for the utilization of IEDs during presurgical evaluations...

Epilepsy is one of the most common chronic neurological diseases, and its pharmacological treatment holds great importance for both physicians and national authorities, especially considering the high proportion of drug-resistant patients (about 30%). Lacosamide (LCM) is an effective and well-tolerated new-generation antiepileptic drug (AED), currently licensed as add-on therapy for partial-onset seizures. However, LCM mechanism of action is still a matter of debate, although its effect on the voltage sensitive sodium channels is by far the most recognized...

BACKGROUND: Statins possess neuroprotective effects. However, real-world evidence supporting their utility in post-stroke epilepsy (PSE) prevention is limited. OBJECTIVE: The association between statin use, including timing of prescribing (pre-stroke vs post-stroke), type (lipophilicity, intensity of therapy) and dose intensity, and risk of developing PSE were investigated by studying Taiwanese health claims (2003-2013). METHODS: Patients with new-onset ischaemic stroke were identified...

REVIEW
Alexis Arzimanoglou, O'Neill D'Cruz, Douglas Nordli, Shlomo Shinnar, Gregory L Holmes
Most antiepileptic drugs (AEDs) receive regulatory approval for children years after the drug is available in adults, encouraging off-label use of the drug in children and hindering attempts to obtain quality pediatric data in controlled trials. Extrapolating adult efficacy data to pediatrics can reduce the time between approval in adults and that in children. To extrapolate efficacy from adults to children, several assumptions must be supported, such as (1) a similar disease progression and response to interventions in adults and children, and (2) similar exposure response in adults and children...

BACKGROUND: KARS encodes lysyl- transfer ribonucleic acid (tRNA) synthetase, which catalyzes the aminoacylation of tRNA-Lys in the cytoplasm and mitochondria. Eleven families/sporadic patients and 16 different mutations in KARS have been reported to date. The associated clinical phenotype is heterogeneous ranging from early onset encephalopathy to isolated peripheral neuropathy or nonsyndromic hearing impairment. Recently additional presentations including leukoencephalopathy as predominant cerebral involvement or cardiomyopathy, isolated or associated with muscular and cerebral involvement, have been reported...
