Bursts of seizures in long-term recordings of human focal epilepsy

Summary

Objective

We report on temporally clustered seizures detected from continuous long-term ambulatory human electroencephalographic data. The objective was to investigate short-term seizure clustering, which we have termed bursting, and consider implications for patient care, seizure prediction, and evaluating therapies.

Methods

Chronic ambulatory intracranial electroencephalography (EEG) data collected for the purpose of seizure prediction were annotated to identify seizure events. A detection algorithm was used to identify bursts of events. Burst events were compared to nonburst events to evaluate event ...

Carvacrol after status epilepticus (SE) prevents recurrent SE, early seizures, cell death, and cognitive decline

Summary

Objective

Carvacrol is a naturally occurring monoterpenic phenol that has been suggested to have an action at transient receptor potential cation subfamily M7 (TRPM7) channels, γ-aminobutyric acid (GABAA receptors, and sodium channels, and has been shown to be antiinflammatory. Carvacrol is neuroprotective in models of cerebral ischemia in vivo and in vitro, probably through its action at TRPM7 channels. We therefore aimed to determine the effect of carvacrol on status epilepticus (SE), chronic epilepsy, cell death, and post-SE ...

De novo SCN1A pathogenic variants in the GEFS+ spectrum: Not always a familial syndrome

Summary

Genetic epilepsy with febrile seizures plus (GEFS+) is a familial epilepsy syndrome characterized by heterogeneous phenotypes ranging from mild disorders such as febrile seizures to epileptic encephalopathies (EEs) such as Dravet syndrome (DS). Although DS often occurs with de novo SCN1A pathogenic variants, milder GEFS+ spectrum phenotypes are associated with inherited pathogenic variants. We identified seven cases with non-EE GEFS+ phenotypes and de novo SCN1A pathogenic variants, including a monozygotic twin pair. Febrile seizures plus (FS+) occurred ...

Use of the ketogenic diet in the neonatal intensive care unit—Safety and tolerability

Summary

Drug-resistant epilepsy poses a challenge in neonatal patients, especially those in the neonatal intensive care unit (NICU), who have various secondary comorbidities. We present results of four children with a history of drug-resistant epilepsy for whom a ketogenic diet was initiated and used in the NICU. A nonfasting induction into ketosis over 1–2 weeks was utilized, with gradual increases in the ketogenic ratio every 2–3 days. Data were collected retrospectively from a database, which included medical history, ...

Current standards of neuropsychological assessment in epilepsy surgery centers across Europe

Summary

We explored the current practice with respect to the neuropsychological assessment of surgical epilepsy patients in European epilepsy centers, with the aim of harmonizing and establishing common standards. Twenty-six epilepsy centers and members of “E-PILEPSY” (a European pilot network of reference centers in refractory epilepsy and epilepsy surgery), were asked to report the status of neuropsychological assessment in adults and children via two different surveys. There was a consensus among these centers regarding the role of neuropsychology ...

Depression screening tools in persons with epilepsy: A systematic review of validated tools

Summary

Objective

Depression affects approximately 25% of epilepsy patients. However, the optimal tool to screen for depression in epilepsy has not been definitively established. The purpose of this study was to systematically review the literature on the validity of depression-screening tools in epilepsy.

Methods

MEDLINE, EMBASE, and PsycINFO were searched until April 4, 2016 with no restriction on dates. Abstract, full-text review and data abstraction were conducted in duplicate. We included studies that evaluated the validity of depression-screening tools and ...

WONOEP appraisal: Biomarkers of epilepsy-associated comorbidities

Summary

Neurologic and psychiatric comorbidities are common in patients with epilepsy. Diagnostic, predictive, and pharmacodynamic biomarkers of such comorbidities do not exist. They may share pathogenetic mechanisms with epileptogenesis/ictogenesis, and as such are an unmet clinical need. The objectives of the subgroup on biomarkers of comorbidities at the XIII Workshop on the Neurobiology of Epilepsy (WONOEP) were to present the state-of-the-art recent research findings in the field that highlighting potential biomarkers for comorbidities in epilepsy. We review recent ...
