Quantification of diffuse and focal delta activity in hypsarrhythmia

Brain and Development, 1990
In order to determine whether or not there is any correlation between the various aspects of hypsarrhythmia and the etiology, we studied one of the major components of this pattern, delta activity, in patients with infantile spasms. In 3 different etiologic groups of patients (prenatal, perinatal and cryptogenic) we divided this activity into 2 types ...

Angelman syndrome and pseudo‐hypsarrhythmia: a diagnostic pitfall

Epileptic Disorders, 2011
ABSTRACTAngelman syndrome is a rare genetic disorder scarcely diagnosed before the age of two years. We report the case of an eight‐month‐old female presenting with severe hypotonia, myoclonus, suspected spasms and an electroencephalogram with hypsarrhythmic‐like features.

The origin of hypsarrhythmia and tonic spasms in West syndrome: evidence from a case of porencephaly and hydrocephalus with focal hypsarrhythmia

Brain and Development, 1999
We report on a 3-year-old girl with West syndrome and with focal hypsarrhythmia. The left hemisphere of the patient was virtually completely defective and continuous hypsarrhythmia was only seen in the residual right frontal cortex, where an interictal single photon emission computed tomography (SPECT) showed hyperperfusion.

Persistence of Hypsarrhythmia in Children Beyond the Age of Three Years

Journal of Child Neurology, 2011
Occurrence of hypsarrhythmia after the age of 3 years is rare. The objective of this study is to describe a group of patients who have persistence of hypsarrhythmia after the age of 3 years. The authors retrospectively reviewed the EEGs of 24 patients with hypsarrhythmia. Electroencephalographies (EEGs) were scored using a hypsarrhythmia scale.

HYPSARRHYTHMIA DEVELOPING IN HOSPITAL: RECOVERY WITH EARLY TREATMENT

Journal of Paediatrics and Child Health, 1971
SYNOPSISA child admitted to hospital with a fractured skull had a normal EEG. While in hospital, he developed the clinical and electroencephalographic features of hypsarrhythmia. Treatment with corticotrophin controlled the seizures, the EEG reverted to normal, and the child's subsequent mental and motor development has been satisfactory.
