Prevalence of Refractory Juvenile Myoclonic Epilepsy
Juvenile myoclonic epilepsy (JME) is a common form of generalized epilepsy. Although the prognosis of JME is not clear, it is assumed to have a good response to treatment. The authors of this meta-analysis found a higher than expected prevalence of refractoriness in JME, which will affect how neurologists counsel patients with JME.

Witness Observations in Diagnosing Transient Loss of Consciousness
These investigators found that adding witness-reported observations to patient demographics and patient-reported symptoms improved the diagnostic accuracy between epilepsy, syncope, and psychogenic nonepileptic seizures.

Utility of Ictal Magnetoencephalography for Identifying Seizure Onset Zone
In a review of 377 magnetoencephalography (MEG) studies in epilepsy patients undergoing presurgical workup, 44 patients were found to have one or more seizures during routine recordings, lasting up to a mean of 51.2 minutes. Ictal MEG provided unique localizing data in about one-third of patients. For patients with frequent seizures or reliably induced seizures, MEG may be a useful supplemental tool for medically refractory epilepsy patients undergoing presurgical evaluation.

Which Is Better for Nonconvulsive Seizures: Lacosamide or Fosphenytoin?
Intravenous lacosamide was found to be noninferior to fosphenytoin in the treatment of nonconvulsive seizures in a prospective, multicenter, randomized clinical trial.

Cannabidiol for Pediatric Seizures
Three months of cannabidiol-enriched cannabis extract decreased mean monthly seizure frequency in children and young adults with refractory epilepsy.

Cannabidiol: Does It Help in Drug-resistant Epileptic Encephalopathies?
In this double-blind, placebo-controlled trial, the authors investigated the efficacy of adjunctive cannabidiol in a population of severe developmental epileptic encephalopathies and found some efficacy.

What Are the Early Predictors for Post-traumatic Epilepsy After Injury?
Following traumatic brain injury, early (first five days after injury) epileptiform abnormalities on EEG were seen more commonly in patients with subsequent post-traumatic epilepsy (PTE), compared to controls, and were found to be a significant and independent predictor of PTE. The presence of subdural hemorrhage was the only other independent predictor of PTE.

Phenytoin as a Second-line Treatment for Status Epilepticus: What’s the Evidence?
In this systematic review, the evidence supporting the use of intravenous phenytoin for convulsive status epilepticus was analyzed critically and did not demonstrate strong evidence to support its use as a preferred second-line agent.

Pitfalls in the Treatment of Seizures Associated With Brain Tumors
In this multicenter, observational study, the authors assessed the prevalence of neuropsychiatric side effects from medications in subjects with tumor-related epilepsy. Levetiracetam was found to have the highest prevalence of such side effects.

Risk Factors for Seizures in Critically Ill Patients Monitored by Continuous EEG
Investigators prospectively analyzed 72-hour continuous electroencephalograms to identify clinical and electroencephalogram risk factors for having seizures and developed a model for “time-dependent” seizure risk. Electrographic seizures occurred in 23% of all patients. The only significant clinical predictors of seizures were presence of coma and prior clinical seizure history.
