The efficacy of epilepsy surgery depends critically upon successful localization of the epileptogenic zone. Magnetoencephalography (MEG) enables noninvasive detection of interictal spike activity in epilepsy, which can then be localized in three dimensions using magnetic source imaging (MSI) techniques. However, the clinical value of MEG in the presurgical epilepsy evaluation is not fully understood, as studies to date are limited by either a lack of long-term seizure outcomes or small sample size. ⋯ MEG is a valuable tool for noninvasive interictal spike mapping in epilepsy surgery, including patients with nonlocalized findings receiving long-term EEG monitoring, and localization of the epileptogenic zone using MEG is associated with improved seizure outcomes.

Continuous electroencephalography (cEEG) is important for treatment guidance in status epilepticus (SE) management, but its role in clinical outcome prediction is unclear. Our aim is to determine which cEEG features give independent outcome information after correction for clinical predictor. ⋯ After adjustment for relevant clinical findings, including SE severity and etiology, cEEG background information (posterior dominant rhythm and sleep patterns) is more predictive for clinical outcome after SE than are rhythmic and periodic patterns or seizures.

To develop and validate a shortened version of the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). A secondary aim was to compare baseline risk factors predicting health-related quality of life (HRQoL) in children newly diagnosed with epilepsy, as identified using the original and shortened version. ⋯ Results offer initial evidence regarding reliability and validity of the proposed 55-item shortened version of the QOLCE (QOLCE-55). The QOLCE-55 produced results on risk factors consistent with those found using the original measure. Given the fewer items, QOLCE-55 may be a viable option reducing respondent burden when assessing HRQoL in children with epilepsy.

Determine prevalence and incidence of epilepsy within two health insurance claims databases representing large sectors of the U.S. ⋯ The large number of patients identified as having epilepsy is statistically robust and provides a credible estimate of the prevalence of epilepsy. Our study draws from multiple U.S. population sectors, making it reasonably representative of the U.S.-insured population.

Although shorter time to pediatric resective epilepsy surgery is strongly associated with greater disease severity, other nonclinical diagnostic and sociodemographic factors also play a role. We aimed to examine parent-reported barriers to timely receipt of pediatric epilepsy surgery. ⋯ Multipronged interventions targeting parent-, provider-, and system-based barriers should focus on the critical presurgical referral period; such interventions are needed to remediate delays and improve access to subspecialty care for children with medically refractory epilepsy and potentially eligible for surgery.
