Quantification of Hypsarrhythmia in Infantile Spasmatic EEG: A Large Cohort Study [PDF]
IEEE Transactions on Neural Systems and Rehabilitation EngineeringInfantile 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.

The significance of focal pattern in hypsarrhythmia
Brain DisordersIntroduction: 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 ...

Connectivity Analysis of Hypsarrhythmia-EEG for Infants With West Syndrome
IEEE Transactions on Neural Systems and Rehabilitation EngineeringDetection 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.

Identification of Hypsarrhythmia in Children with Microcephaly Infected by Zika Virus [PDF]
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 ...

Short-Term Changes in Hypsarrhythmia Assessed by Spectral Analysis: Group and Individual Assessments. [PDF]
Clin EEG NeurosciObjectives: To perform spectral analysis on previously recorded electroencephalograms (EEGs) containing hypsarrhythmia in an initial recording and to assess changes in spectral power (µV2) in a follow-up recording after a period of 10–25 days.

Hypsarrhythmia Variant Patterns
Pediatric Neurology Briefs, 1997 The frequency of hypsarrhythmia variant or atypical patterns was determined by analysis of pre-ACTH EEG records of 53 consecutive patients with infantile spasms at Children’s Hospital, Harvard Medical School, Boston, MA.

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