Depression is a common comorbidity of epilepsy, and its timely identification in persons with epilepsy is essential. The use of screening tools to detect depression is common in epilepsy, but some scales in current use have not been validated using a gold standard in this population. The present study aims to validate three commonly used depression-screening scales and assess new cut points for scoring in those with epilepsy. ⋯ The PHQ-9 at a cut point of 9 and the HADS at a cut point of 7 had the best overall balance of sensitivity and specificity. However, for screening purposes the PHQ-9 algorithm method is ideal (optimizing specificity), whereas for case finding the HADS at a cut point of 6 performed best (optimizing sensitivity). Appropriate scale cut points should be chosen based on the study's goals and available resources. Disease-specific scale cut points are recommended for future studies assessing depression in persons with epilepsy.

Autosomal dominant lateral temporal epilepsy (ADLTE) is a focal epileptic syndrome characterized by auditory or aphasic auras. Mutations in the LGI1 gene account for <50% of ADLTE families. To identify copy number variants (CNVs) related to ADLTE, we examined a collection of ADLTE families without LGI1 mutations. ⋯ Our results provide clues on genes for susceptibility to ADLTE, particularly in those families where the inheritance pattern is less compatible with autosomal dominance. Some of these genes also confer risk for other epilepsy syndromes.

Randomized Controlled Trial Multicenter Study Comparative Study
Long-term safety and efficacy of zonisamide versus carbamazepine monotherapy for treatment of partial seizures in adults with newly diagnosed epilepsy: results of a phase III, randomized, double-blind study.
To investigate the long-term safety and maintenance of efficacy of monotherapy with once-daily zonisamide versus twice-daily controlled-release carbamazepine for partial seizures in adults with newly diagnosed epilepsy. ⋯ Once-daily zonisamide monotherapy demonstrated favorable long-term safety and maintenance of efficacy in treating partial seizures in adults with newly diagnosed epilepsy. No new or unexpected safety findings emerged.

Multicenter Study
Vagus nerve stimulation for drug-resistant epilepsy: a European long-term study up to 24 months in 347 children.
To gain insight into the long-term impact of vagus nerve stimulation (with VNS Therapy) in children with drug-resistant epilepsy, we conducted the largest retrospective multicenter study to date over an extended follow-up period of up to 24 months. ⋯ The results demonstrate that adjunctive VNS Therapy in children with drug-resistant epilepsy reduces seizure frequency and is well tolerated over a 2-year follow-up period. No new safety issues were identified. A post hoc analysis revealed a dose-response correlation for VNS in patients with epilepsy.

The burden of epilepsy, in terms of both morbidity and mortality, is likely to vary depending on the etiology (primary [genetic/unknown] vs. secondary [structural/metabolic]) and with the use of antiepileptic drugs (AEDs). We estimated the disability-adjusted life years (DALYs) and modeled the remission rates of active convulsive epilepsy (ACE) using epidemiologic data collected over the last decade in rural Kilifi, Kenya. ⋯ The DALYs for ACE are high in rural Kenya, but less than the estimates of 2010 GBD study. Three-fourths of DALYs resulted from secondary epilepsy. Use of AEDs was associated with 40% reduction of DALYs. Improving adherence to AEDs may reduce the burden of epilepsy in this area.
