Hypsarrhythmia is associated with widespread, asymmetric cerebral hypermetabolism [PDF]

Seizure, 2019
Hypsarrhythmia is the interictal EEG pattern most often associated with infantile spasms. We set out to evaluate the metabolic impact of hypsarrhythmia among patients with infantile spasms by contrasting regional cerebral metabolic activity among children with and without hypsarrhythmia.Patients with video-EEG confirmed infantile spasms who underwent ...

Interictal EEG features as computational biomarkers of West syndrome [PDF]

Frontiers in Pediatrics
BackgroundWest syndrome (WS) is a devastating epileptic encephalopathy with onset in infancy and early childhood. It is characterized by clustered epileptic spasms, developmental arrest, and interictal hypsarrhythmia on electroencephalogram (EEG ...

Asymmetric Hypsarrhythmia: Clinical Electroencephalographic and Radiological Findings [PDF]

Epilepsia, 1995
Summary: Twenty‐six children (16 boys and 10 girls) with hypsarrhythmia and infantile spasms (IS) were studied at the University of Michigan EEG Laboratory in a 4‐year period. Six (2 boys, 4 girls), had asymmetric hypsarrhythmia with a preponderance of both slowing and epileptic form activity over one hemisphere.

Case report: De novo variant of SETD1A causes infantile epileptic spasms syndrome [PDF]

Frontiers in Neurology, 2023
Infantile epileptic spasms syndrome (IESS) is one of the most common epileptic encephalopathies of infancy, with typical clinical features defined by a triad of epileptic spasms, hypsarrhythmia, and developmental delay.

Is hypsarrhythmia a form of non-convulsive status epilepticus in infants?

Acta Neurologica Scandinavica, 2007
Hypsarrhythmia is generally associated with infantile spasms, a combination referred to as West syndrome. It is debatable whether hypsarrhythmia is usefully regarded as a form of non-convulsive status epilepticus (NCSE).The earliest English language description of hypsarrhythmia reported an almost continuous EEG pattern, although later studies showed a

Dental Considerations and Treatment Approaches in West Syndrome—Infantile Spasms: A Case Report [PDF]

Journal of South Asian Association of Pediatric Dentistry, 2023
Introduction: West syndrome (WS) comprises a classic triad of infantile spasms (ISs), hypsarrhythmia, and psychomotor delay. It is considered a rare epileptic encephalopathy typical to manifest in infancy or early childhood.

Early transient dysautonomia predicts the risk of infantile epileptic spasm syndrome onset: A prospective cohort study

Frontiers in Neurology, 2022
BackgroundInfantile epileptic spasm syndrome (IESS) is an age-dependent epileptic encephalopathy with a significant risk of developmental regression. This study investigates the association between heart rate variability (HRV) in infants at risk of IESS ...

Annals of Medical Science and Research, 2023
West syndrome is a severe epilepsy syndrome characterized by the classical triad of infantile spasms, hypsarrhythmia on electroencephalography (EEG) and psychomotor retardation.
