Scoring Systems for the Evaluation of Hypsarrhythmia
Journal of Clinical Neurophysiology, 2022Summary: Hypsarrhythmia is a well-recognized EEG pattern and it has been long known as a feature of one of the more severe forms of epilepsy early in life with adverse consequences if not recognized and treated promptly. Yet, it has been difficult to objectively quantify its varied manifestations and link them to the clinical severity of ...

Quantitative Characteristics of Hypsarrhythmia in Infantile Spasms
2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018Infantile spasms is a type of epilepsy characterized by clinical seizures termed "spasms" and often an electroencephalographic (EEG) pattern known as hypsarrhythmia. Multiple studies have shown that the interrater reliability for human visual recognition of hypsarrhythmia is poor.

Is the EEG really "chaotic" in hypsarrhythmia
IEEE Engineering in Medicine and Biology Magazine, 2001The authors conclude that the hypsarrhythmic EEG shares less features with EEGs with generalized seizure activity than suggested by the often used adjective "chaotic" in the description of the visually inspected time series. Although the hypsarrhythmic EEG may occasionally contain some weak nonlinear structures, as in the control EEGs, the authors ...

Hypsarrhythmia and infantile autism: A clinical report
Journal of Autism and Childhood Schizophrenia, 1971The case histories of five children, four boys and one girl (1 to 9 years of age), who developed autistic behavior after the onset of infantile spasms, are presented in detail. The patients' initial EEGs disclosed hypsarrhythmia. First onsets of seizures occurred during the second 6 months of life in four and on the third day of life in the youngest ...

[Epileptic spasms in infants. Beyond hypsarrhythmia].
Revista de neurologia, 2018Epileptic spasms are the most frequent type of epileptic seizures in infants. They can also occur beyond the period of infancy, within the context of other epileptic encephalopathies or as an expression of a focal or generalised epilepsy. The clinical semiology of epileptic spasms varies greatly.

[Infantile spasms and modified hypsarrhythmia].
Harefuah, 2011The West syndrome was described by the physician West in his own son in 1841 and is defined as a triad of myoclonic seizures called "infantile spasms", electrographic abnormalities called "hypsarrhythmia" and arrest of psychomotor development and mental retardation.
