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. ⋯ This analysis describes initial comparative benefits of two newly available AEDs in two cohorts of patients with highly refractory epilepsies. Responder and seizure freedom rates were numerically higher for PER. The analysis suggests that new AEDs can provide a chance for seizure freedom in relevant subgroups of patients, despite previous failure of multiple AEDs.

Epilepsy has been recognized as a brain network disorder. Therefore, functional MRI (fMRI)-based connectivity is an ideal technique for exploring the complex effects of epilepsy on the brain. Functional connectivity studies have provided insights into the physiopathogenesis of the epileptic network underlying focal epilepsies, genetic generalized epilepsy, and specific epileptic syndromes. ⋯ Researchers who have examined predictors of surgical outcomes have suggested that there might be identifiable pre-surgical patterns of functional connectivity that are associated with a greater likelihood of positive cognitive or seizure outcomes. However, knowledge regarding the role of fMRI connectivity remains limited in clinical settings. Further validation through invasive investigations and follow-up studies is required for its reliable application in the clinical management of individual patients.

From nocturnal frontal lobe epilepsy to Sleep-Related Hypermotor Epilepsy: A 35-year diagnostic challenge.
Nocturnal frontal lobe epilepsy (NFLE) is a focal epilepsy with seizures arising mainly during sleep and characterized by complex, often bizarre, motor behavior or sustained dystonic posturing. First described in 1981, it was initially considered a motor disorder of sleep and was named nocturnal paroxysmal dystonia (NPD). The unusual seizure semiology, onset during sleep, and often uninformative scalp EEG and brain MRI make it difficult to distinguish NPD attacks from other non-epileptic nocturnal paroxysmal events, namely parasomnias. ⋯ To address controversial issues and define the diagnostic criteria for NFLE, a Consensus Conference was held in Bologna, Italy in 2014. Major points of agreement emerged on: (i) the relationship of the seizures with sleep and not with the circadian pattern of seizure occurrence; (ii) the possible extrafrontal origin of hypermotor seizures, without substantial differences in seizure semiology. In the wake of the Consensus, the syndrome was renamed Sleep-Related Hypermotor Epilepsy (SHE).

to evaluate the efficacy and safety of intravenous (IV) lacosamide (LCM) in the treatment of seizure clusters (SC) and status epilepticus (SE) in hospitalized adult patients. ⋯ LCM is an effective and well-tolerated treatment when used to treat SC in hospitalized adult patients. As add-on therapy, it may be useful to stop seizure activity in patients with focal SE not responding to first/second-line intravenous AEDs.

We aimed to study whether ketogenic diet (KD) therapy leads to resolution of super-refractory status epilepticus in pediatric patients without significant harm. ⋯ Most patients achieved resolution of status epilepticus on KD therapy, suggesting it could be an effective therapy that can be utilized early in the treatment of children with super refractory status epilepticus.
