Purpose: While antidepressants are recommended to manage anxiety or depression in epilepsy, limited effectiveness data exist in real-world epilepsy samples, and prior work indicated frequent positive screens despite antidepressant prescription. In response, this study evaluates factors associated with positive anxiety or depression screen during ongoing antidepressant prescription.

Methods: Clinical and sociodemographic characteristics were collected among consecutive adult epilepsy clinic patients completing validated anxiety and depression instruments.

Introduction: Anti-seizure medications are used to manage epilepsy and require long-term adherence to maintain therapeutic drug levels. We assessed adherence to levetiracetam and the use of a digital intervention to improve adherence in patients with epilepsy.

Methods: 30 participants with epilepsy were randomized 1:1 either to a digital email adherence intervention or control group.

Background: Drugs that increase inhibitory neuronal activity in the brain have been proposed as potential medications for stimulant use disorders.

Objective: The present study assessed the ability of chronically administered levetiracetam (Keppra®), a clinically available anticonvulsant drug that increases GABA by binding to synaptic vesicle glycoprotein 2A, to modulate the reinforcing strength of cocaine in monkeys.

Methods: Three adult male rhesus monkeys (Macaca mulatta) self-administered cocaine intravenously each day under a progressive-ratio (PR) schedule of reinforcement.

Objective: Anxiety and depression in epilepsy are prevalent, associated with poor outcomes, underrecognized, undertreated, and thus a key area of need for treatment research. The objective of this study was to assess factors associated with research participation among epilepsy clinic patients who screened positive for anxiety or depression. This was accomplished by characterizing clinical and psychiatric factors among patients seen in an epilepsy clinic and evaluating which factors were associated with consent for potential research participation, via a combined clinical and research screening model.

Burnout is highly prevalent among physicians and has been associated with negative outcomes for physicians, patients, staff, and health-care organizations. Reducing physician burnout and increasing physician well-being is a priority. Systematic reviews suggest that organization-based interventions are more effective in reducing physician burnout than interventions targeted at individual physicians.

Objective: To study prevalence of and factors contributing to burnout, career satisfaction, and well-being in US neurology residents and fellows.

Methods: A total of 938 US American Academy of Neurology member neurology residents and fellows were surveyed using standardized measures of burnout, career satisfaction, and well-being from January 19 to March 21, 2016.

Results: Response rate was 37.

Magnetoencephalography (MEG) provides useful and non-redundant information in the evaluation of patients with epilepsy, and in particular, during the pre-surgical evaluation of pharmaco-resistant epilepsy. Vagus nerve stimulation (VNS) is a common treatment for pharmaco-resistant epilepsy. However, interpretation of MEG recordings from patients with a VNS is challenging due to the severe magnetic artifacts produced by the VNS.

Objective: To demonstrate the safety and effectiveness of responsive stimulation at the seizure focus as an adjunctive therapy to reduce the frequency of seizures in adults with medically intractable partial onset seizures arising from one or two seizure foci.

Methods: Randomized multicenter double-blinded controlled trial of responsive focal cortical stimulation (RNS System). Subjects with medically intractable partial onset seizures from one or two foci were implanted, and 1 month postimplant were randomized 1:1 to active or sham stimulation.

Status epilepticus is a life threatening condition with a high mortality rate in spite of aggressive treatment. There is little consensus on third and fourth line approaches in refractory cases. While electroconvulsive therapy (ECT) has been employed successfully as a treatment for refractory epilepsy and status epilepticus (SE) after exhausting conventional therapy, its use for pediatric patients is limited.

Study Objective: To determine the outcome in patients with sleep complaints and normal polysomnograms (PSG).

Background: PSG is used in the evaluation of persons with sleep complaints. There is a small amount of literature available on patients with sleep complaints and normal PSGs.

Episodic hemipareis is usually thought to have a vascular etiology. Ictal paresis during seizures usually occurs with other clinical signs. The exact mechanism by which weakness occurs during seizures is difficult to determine as positive and negative motor phenomenona occur in rapid succession.

Background: To our knowledge, no study to date has investigated the prescribing patterns of immunomodulatory agents (IMAs) in an outpatient setting in the United States. To address this issue, we performed retrospective data analyses on National Ambulatory Medical Care Survey (NAMCS) data for MS patient visits between 1998 and 2004.

Methods: NAMCS data are a weighted estimate of the nationwide frequency of patients' outpatient clinic visits.

Purpose: We analyzed the occurrence and clinical features of myoclonus in patients with end-stage renal disease (ESRD) who were treated with gabapentin (GBP).

Methods: We reviewed the medical records of patients with ESRD who were treated with GBP and hospitalized during an 18-month period and analyzed clinical details such as type of myoclonus, doses of GBP, electroencephalographic (EEG) findings, and relation of symptoms to GBP exposure and dosage.

Results: Three of 71 patients had myoclonus with GBP doses ranging from 9 mg/kg to 20 mg/kg and within 4 months of treatment onset.

Background: Electroencephalography (EEG) is traditionally used to assess the duration of hemispheric anesthetization and to monitor return of function in the anesthetized hemisphere during the intracarotid amobarbital procedure (IAP), but EEG changes are not consistently seen. The authors evaluated the role of continuous transcranial Doppler (TCD) monitoring as an alternative to EEG.

Methods: The authors performed both continuous TCD monitoring and EEG during the IAP in 10 patients with medically intractable partial epilepsy.
