Epilepsy‐Associated Variants of a Single SCN1A Codon Exhibit Divergent Functional Properties

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Pathogenic variants in SCN1A, which encodes the voltage‐gated sodium channel NaV1.1, are associated with multiple epilepsy syndromes exhibiting a range of clinical severity. SCN1A variants are reported in different syndromes, including Dravet syndrome, which is associated with loss‐of‐function, whereas neonatal/infantile‐onset ...

Antimicrobial‐associated encephalopathy due to ampicillin

open access: yesClinical Case Reports
Key Clinical Message Because the β‐lactam ring has a molecular structure similar to that of gamma‐aminobutyric acid (GABA) neurotransmitters, it binds to GABA A receptors and inhibits GABAergic transmission, causing AAE.

ALDOA Promotes Glycolysis and NLRP3/GSDMD Pyroptosis to Accelerate ALS Progression

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is characterized by progressive motor neuron degeneration. Glycolytic dysregulation is implicated in disease progression, yet the underlying mechanisms remain unclear. This study investigates how Aldolase A (ALDOA) drives ALS progression through glycolysis‐mediated motor neuron pyroptosis.
