Effect of Primidone on Dentate Nucleus γ-Aminobutyric Acid Concentration in Patients With Essential Tremor [PDF]

, 2016
OBJECTIVES: It is not known whether current use of the medication primidone affects brain γ-aminobutyric acid (GABA) concentrations. This is an important potential confound in studies of the pathophysiology of essential tremor (ET), one of the most ...

A Comprehensive Overview of the Clinical, Electrophysiological, and Neuroimaging Features of BPAN: Insights From a New Case Series

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Neurodegeneration with brain iron accumulation (NBIA) comprises a genetically and clinically heterogeneous group of rare neurological disorders characterized particularly by iron accumulation in the basal ganglia. To date, 15 genes have been associated with NBIA.

Retinal nerve fibre layer thinning is associated with drug resistance in epilepsy. [PDF]

, 2015
Retinal nerve fibre layer (RNFL) thickness is related to the axonal anterior visual pathway and is considered a marker of overall white matter 'integrity'. We hypothesised that RNFL changes would occur in people with epilepsy, independently of vigabatrin

Expanding the Phenotype of CYFIP2‐Related Developmental Epileptic Encephalopathy: Case Report and Literature Review

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Background Pathogenic CYFIP2 variants cause developmental and epileptic encephalopathy (DEE), characterized by early‐onset intractable epilepsy and developmental delay. The disease course has not been delineated. Codon Arg87 is a de novo mutational hotspot associated with a severe DEE phenotype via gain‐of‐function mechanisms. Currently, there

Epilepsy syndromes classification

Epilepsia Open, EarlyView.
Abstract Epilepsy syndromes are distinct electroclinical entities which have been recently defined by the International League Against Epilepsy Nosology and Definitions Task Force. Each syndrome is associated with “a characteristic cluster of clinical and EEG features, often supported by specific etiologic findings”.

Towards a Synthesis of Vigabatrin Using Glycal Chemistry

Molecules, 2005
Application of the Ferrier rearrangement led to a novel carbohydrate based synthetic route to 4-aminohexenoic acid viz. (R) and (S)-vigabatrin. The potential of D- glucose or D-galactose as the chiral starting materials for the synthesis of (R) and (S ...

Biallelic mutations in valyl-tRNA synthetase gene VARS are associated with a progressive neurodevelopmental epileptic encephalopathy. [PDF]

, 2019
Aminoacyl-tRNA synthetases (ARSs) function to transfer amino acids to cognate tRNA molecules, which are required for protein translation. To date, biallelic mutations in 31 ARS genes are known to cause recessive, early-onset severe multi-organ diseases ...

Intestinal microbiome alterations in pediatric epilepsy: Implications for seizures and therapeutic approaches

Epilepsia Open, EarlyView.
Abstract The intestinal microbiome plays a pivotal role in maintaining host health through its involvement in gastrointestinal, immune, and central nervous system (CNS) functions. Recent evidence underscores the bidirectional communication between the microbiota, the gut, and the brain and the impact of this axis on neurological diseases, including ...

New insights into epileptic spasm generation and treatment from the TTX animal model

Epilepsia Open, EarlyView.
Abstract Currently, we have an incomplete understanding of the mechanisms underlying infantile epileptic spasms syndrome (IESS). However, over the past decade, significant efforts have been made to develop IESS animal models to provide much‐needed mechanistic information for therapy development.
