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 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

The Treatment of Infantile Spasms and Hypsarrhythmia with Mogadon
Epilepsia, 1967 SUMMARYReport about experiences with Mogadon in the treatment of 24 children with infantile spasms and hypsarrhythmia. Control of spasms was obtained, together with improvement or normalisation of the EEG, in 13 out of the 24 cases described. Among the side‐effects of Mogadon, hypersecretion in the respiratory tract is the most troublesome.

Summary: The initial description of infantile spasms and its association to developmental abnormalities was attributed to Dr. Williams J. West in 1841 but the clinical scenario at the time had also been seen by other physicians.

The Diminishing Incidence of Hypsarrhythmia
Clinical Electroencephalography, 1985The 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.

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 ...
