The Diminishing Incidence of Hypsarrhythmia

Clinical Electroencephalography, 1985
The incidence of hypsa over a 40-year period in 667 pts was noted to rise to a peak in 1958 and then to fall so that relatively few cases appeared in the early 1970's, with hypsa seen only rarely in the past 10 years. This diminishing incidence was confirmed in a major children's hospital.

Hypsarrhythmia: Variations on the Theme

Epilepsia, 1984
Summary: Prolonged monitoring studies of patients with infantile spasms have shown that hypsarrhythmia is a highly variable and dynamic electroencephalographic pattern. Variations of the prototypic pattern (modified hypsarrhythmia) include hypsarrhythmia with increased in‐terhemispheric synchronization, asymmetrical hypsarrhythmia, hypsarrhythmia with

Scoring Systems for the Evaluation of Hypsarrhythmia

Journal of Clinical Neurophysiology, 2022
Summary: 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 ...

Hypsarrhythmia

Neurology, 1997
To determine the frequency and significance of the EEG features of hypsarrhythmia, we analyzed the pre-ACTH records of 53 consecutive patients with infantile spasms for the severity of the following abnormalities: disorganization of background, slowing, high amplitude, spike activity, and for the presence or absence of each of the following patterns ...

Is the EEG really "chaotic" in hypsarrhythmia

IEEE Engineering in Medicine and Biology Magazine, 2001
The 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 ...

Infection as a Possible Etiology of Hypsarrhythmia

Clinical Electroencephalography, 1986
Summary In 480 patients with hypsarrhythmia (H) and also in a matched control group (180), evidence for some recent infection was determined as a possible etiology for the H. Evidence for infection was found in 38% of the H patients, significantly (p<0.0005) different from the 23% in the control group.

Quantitative Characteristics of Hypsarrhythmia in Infantile Spasms

2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018
Infantile 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.
