BACKGROUND AND PURPOSE: West syndrome is a developmental and epileptic
encephalopathy characterized by epileptic spasms, neurodevelopmental regression, and a …

Purpose: West syndrome is a severe epileptic encephalopathy of infancy characterized by a
poor developmental outcome and hypsarrhythmia. The pathogenesis of hypsarrhythmia is …

Purpose: A retrospective study for a classification of prehypsarrhythmic
elecroencephalographies (EEGs) was carried out to enable an early treatment option for …

Purpose West syndrome (WS) is a severe age-related acute epileptic encephalopathy of
infancy characterized by infantile spasms, hypsarrhythmia and psychomotor delay. The aim …

Purpose Hypsarrhythmia, the pathognomonic EEG pattern of West syndrome, is typically
characterized by a high amplitude, arrhythmic, and asynchronous pattern. While this …

Magnetoencephalography (MEG) was performed in 7 patients with West syndrome (WS). In
patients who had localized lesions such as tuberous sclerosis and porencephaly in the …

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 …

Objective Fast oscillations (FOs) were first explored from scalp electroencephalographic
(EEG) data from hypsarrhythmia in West syndrome (infantile spasms) to investigate the …

Objective Perinatal arterial ischemic stroke (PAIS) is associated with epileptic spasms of
West syndrome (WS) and long term Focal epilepsy (FE). The mechanism of epileptogenic …

Ictal electroencephalographic/video recordings of 42 patients with West syndrome (WS)
were reviewed to define the relation between ictal, clinical, and EEG features and etiology or …
