Article Abstract
Objective: To understand the current burden of focal epilepsy (FE) as a function of seizure frequency.
Methods: Patients were identified from the United States (2011, 2012, and 2013), five European countries (EU; France, Germany, Italy, Spain, United Kingdom) (2011 and 2013), and Brazil (2011 and 2012) National Health and Wellness Survey (NHWS), a nationally representative, Internet-based survey of adults (18+ years). The NHWS collected data on respondents' quality of life (QoL), health utilities, productivity loss, and healthcare resource utilization. Indirect and direct costs were calculated from the literature. Altogether, 345 of 176,093 (U.S.A.), 73 of 30,000 (United Kingdom), 53 of 30,001 (Germany), 53 of 30,000 (France), 41 of 12,011 (Spain), 37 of 17,500 (Italy), and 71 of 24,000 (Brazil) respondents self-reported a diagnosis of FE.
Results: Many respondents (U.S.A.: 56.2%; 5EU: 41.6%; Brazil + 5EU: 40.5%) reported persistent seizures (≥1 per year). Over 60% to just over 71% of respondents with FE were treated with antiepileptic drugs (AEDs). In the United States, seizure frequency was associated with hospitalizations, indirect costs (ages 18-60), and total direct costs. For the 5EU and Brazil + 5EU, seizure frequency was associated with physical QoL, health utilities, activity impairment, and emergency room (ER) visits. Additional associations were observed for the 5EU on hospitalizations, indirect costs (ages 18-60), ER visit costs, and total direct costs and for Brazil + 5EU on absenteeism, overall work impairment, and provider visits. Costing was not performed for Brazil + 5EU.
Significance: Around half of the patients had persistent seizures despite most taking an AED in this 2011-2013 dataset. The results support the hypothesis that reducing seizures can improve productivity and reduce resource utilization and associated costs. Regional differences may reflect differences in healthcare systems and selected patient populations. Overall, the results suggest that additional treatment options are needed to improve seizure control and reduce related costs.

Lance Adams syndrome (LAS) is characterized by chronic action or intention myoclonus resulting from cerebral hypoxia. Perampanel, a non-competitive antagonist of aamino-3-hydroxy-5methyl-4 isooxazoleproprionic acid glutamate receptor, has demonstrated some efficacy in myoclonic epilepsy and other types of myoclonus. We report significant benefit in a patient with LAS treated with add on perampanel and provide a review of the relevant literature.

Background And Purpose: Epilepsy increases poor outcomes in patients with post-traumatic brain injury and brain tumor-related epilepsy, for whom early seizure control is essential. Perampanel (PER) was a known third-generation antiepileptic drug for treatment all types of seizures. The objective of the study is to compare clinical outcomes and safety of PER administration as monotherapy.

Objective: This study aims to evaluate the efficacy and safety of deep brain stimulation (DBS) of the medial pulvinar nucleus (PuM) in reducing seizure frequency and addressing comorbidities in patients with drug and vagal nerve-resistant focal epilepsy.
Methods: This is an open-label prospective treatment trial with a planned enrollment of 12 patients suffering from medically refractory epilepsy (Clinical trial gov NCT04692701), for which the interim 12-month post-implantation results for the first 6 patients are being reported. Inclusion criteria were focal epilepsy not suitable for or after failed surgical intervention and previous failure of neurostimulation therapies (vagus nerve stimulation or anterior thalamic nucleus DBS).

Neuronal ceroid lipofuscinoses (NCLs) are genetically heterogeneous neurodegenerative disorders, characterized by progressive cognitive and motor decline, epilepsy, visual impairment, and shortened life-expectancy. CLN6-related NCLs include both late-infantile and adult myoclonic form. We report a 21-year-old patient, with mild developmental delay, who developed occipital seizures at 14 years, and subsequently cognitive decline, cortical myoclonus, and photosensitivity at low and higher frequencies.

Introduction: Epilepsy remains a challenge, with one-third of patients experiencing refractory seizures despite current anti-seizure medications. The nitrergic system, which involves nitric oxide (NO) and NO synthase (NOS) enzymes, plays a complex role in seizure pathophysiology. Pentoxifylline (PTPh), an FDA-approved phosphodiesterase inhibitor, has anticonvulsant effects; however, its relationship with the pathway is unclear.
