Alternating hemiplegia of childhood: New diagnostic options [PDF]

, 1970
A syndrome of alternating hemiplegia of childhood (AHC) is a rare disorder first presented in 1971. AHC is characterized by transient episodes of hemiplegia affecting either one or both sides of the body.

Alternating hemiplegia of childhood

, 2023
Alternating hemiplegia of childhood (AHC) is characterized by recurrent episodes of hemiplegia which may alternate sides between attacks. The condition is associated with severe neurodevelopmental disorder presenting in early infancy, and may encompass a

Genetic Variants of Na+,K+‐ATPase Associated With Neurological Disorders: A Systematic Review

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Neurological disorders encompass a wide range of severe symptoms and manifestations, many of which are associated with genetic variants that affect ionic homeostasis. Na+,K+‐ATPase, a transmembrane enzyme responsible for maintaining electrochemical gradients in cells, plays a crucial role in neuronal excitability and brain function.

Reflex seizures and epilepsy surgery: A network approach case‐based exploration

Epileptic Disorders, EarlyView.
Abstract Context Reflex seizures (RS) are defined by their consistent provocation by specific stimuli, encompassing a broad range from elementary sensory inputs to complex cognitive tasks. While RS are often encountered in clinical practice, their surgical management remains sparsely reported and poorly systematized.

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”.

Movement Disorders in Developmental and Epileptic Encephalopathies

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Monogenic developmental and epileptic encephalopathies (DEE) frequently feature co‐occurring movement disorders. Gene discovery has expanded epilepsy‐dyskinesia syndromes (EDS) from classic associations such as stereotypies in Rett syndrome to PRRT2‐related infantile seizures with paroxysmal dyskinesia and crouched gait in SCN1A ...

Novel E815K knock-in mouse model of alternating hemiplegia of childhood

Neurobiology of Disease, 2018
De novo mutations causing dysfunction of the ATP1A3 gene, which encodes the α3 subunit of Na+/K+-ATPase pump expressed in neurons, result in alternating hemiplegia of childhood (AHC).

ATP1A3 mutations and genotype-phenotype correlation of alternating hemiplegia of childhood in Chinese patients. [PDF]

PLoS ONE, 2014
Alternating hemiplegia of childhood (AHC) is a rare and severe neurological disorder. ATP1A3 was recently identified as the causative gene. Here we report the first genetic study in Chinese AHC cohort.
