Objective: To screen a library of potential therapeutic compounds for a woman with Lennox-Gastaut syndrome due to a Y302C GABRB3 (c.905A>G) mutation.
Methods: We compared the electrophysiological properties of cells with wild-type or the pathogenic GABRB3 mutation.
Purpose: Up to a third of patients with epilepsy suffer from recurrent seizures despite therapeutic advances.
Results: Current epilepsy treatments are limited by experiential data from treating different types of epilepsy. For example, we lack evidence-based approaches to efficacious multi-drug therapies or identifying potentially serious or disabling adverse events before medications are initiated.
Purpose Of Review: To review the history, pharmacology, and clinical science of cannabidiol (CBD) in the treatment of epilepsy.
Recent Findings: Phase III randomized controlled trials and prospective open label trials have provided efficacy and safety data for the use of CBD in pediatric onset severe epilepsies. The product that was studied in the vast majority of these published trials, Epidiolex (>99% of CBD and <0.

Objective: Carpal tunnel syndrome (CTS) is diagnosed with electrodiagnostic (EDx) studies. Investigations have examined US cross sectional-area (CSA) and wrist to forearm ratio (WFR) cut-offs for screening EDx abnormalities in patients with suspected CTS. The objective of this study is to determine if these US parameters are effective in a real world population.

We compared outcomes for patients who underwent intracranial stereotactic EEG (SEEG) before and after the adoption of continuous monitoring by a staff bedside sitter. We retrospectively studied 26 consecutive adult patients who underwent SEEG placement at our center over a three-year period.

SLAH is less invasive than open resection, but there are limited series reporting its safety and efficacy, particularly in patients without clear evidence of mesial temporal sclerosis (MTS).
Methods: We report seizure outcomes and complications in our first 30 patients who underwent SLAH for drug-resistant MTLE between January 2013 and December 2016.
Peripheral nerve injury can be reconstructed using composite polymer nerve autografts, but the sonographic appearance of nerve wraps and conduits have not been well documented. This case report describes the sonographic findings in a 42-year-old woman with bilateral carpal tunnel syndrome status post nerve repair with a conduit. The cross-sectional area of the left median nerve was 24 mm at the carpal tunnel inlet and 5 mm at the forearm.

However, it is frequently impractical to perform studies on control subjects to obtain RVs. The Extrapolated Reference Values (E-Ref) procedure extracts RVs from data obtained during clinically indicated EDx testing.

Introduction: Continuous EEG (cEEG) monitoring is used in the intensive care unit (ICU) setting to detect seizures, especially nonconvulsive seizures and status epilepticus. The utility and impact of such monitoring in non-ICU patients are largely unknown.
Methods: Hospitalized patients who were not in an ICU and underwent cEEG monitoring in the first half of 2011 and 2014 were identified.
Seizures are common among patients with brain tumors. Transient, postictal magnetic resonance imaging abnormalities are a long recognized phenomenon. However, these radiographic changes are not as well studied in the brain tumor population.

Ultrasound (US) guidance is not used routinely. The aim of this study was to determine if US guidance of EMG selected muscles would increase the diagnostic yield of the biopsy as compared to the current practice standards.
