Connectivity Analysis of Hypsarrhythmia-EEG for Infants With West Syndrome

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Detection of hypsarrhythmia electroencephalography (EEG) in infants with West syndrome (WS) is currently performed by manual inspection of long-term video/EEG recording, producing low inter-rater reliability.

The significance of focal pattern in hypsarrhythmia

Brain Disorders
Introduction: Infantile Epileptic Spasms Syndrome (IESS) presents a therapeutic challenge and is frequently associated with developmental delay. It is characterized by seizures and hypsarrhythmia on the EEG and has multiple etiologies that influence ...

Quantification of Hypsarrhythmia in Infantile Spasmatic EEG: A Large Cohort Study

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Infantile spasms (IS) is a neurological disorder causing mental and/or developmental retardation in many infants. Hypsarrhythmia is a typical symptom in the electroencephalography (EEG) signals with IS.

Identification of Hypsarrhythmia in Children with Microcephaly Infected by Zika Virus

Entropy, 2019
Hypsarrhythmia is an electroencephalographic pattern specific to some epileptic syndromes that affect children under one year of age. The identification of this pattern, in some cases, causes disagreements between experts, which is worrisome since an ...

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 ...

Epileptic spasms in infants: can video-EEG reveal the disease’s etiology? A retrospective study and literature review

Frontiers in Neurology, 2023
ObjectiveEpileptic spasms are a type of seizure defined as a sudden flexion or extension predominantly of axial and/or truncal limb muscles that occur with a noticeable periodicity. Routine electroencephalogram supports the diagnosis of epileptic spasms,
