The main EEG patterns detected in the patients are listed in Table 1.The presence of a classic or modified hypsarrhythmia or a burst-suppression pattern was associated with drug-resistant epilepsy.

These seizures are accompanied by high-amplitude electroencephalogram (EEG) waveforms, known as hypsarrhythmia. IESS has adverse prognostic implications for intellectual development.

EEG at 5 months showed hypsarrhythmia, as well as electroclinical spasms in the three siblings (Supplementary Figures S1 and S2). Epilepsy onset was associated with psychomotor arrest and poor ...

Hypsarrhythmia: A disorganised, chaotic EEG pattern frequently observed in infants with spasms. West syndrome: A clinical syndrome combining infantile spasms, hypsarrhythmia, ...

Infantile spasms Results found that infants with an unknown epilepsy etiology, a normal MRI, an EEG displaying hypsarrhythmia, or those already receiving an AED were more likely to be administered ...

These seizures are accompanied by high-amplitude electroencephalogram (EEG) waveforms, known as hypsarrhythmia. IESS has adverse prognostic implications for intellectual development.

Symptoms of IS include spasms of the limbs and trunk (extending or stiffening of the arms, legs, neck or trunk) that occur in clusters, an electroencephalography (EEG) pattern of hypsarrhythmia ...

The high incidence of epileptic spasms and hypsarrhythmia has long been emphasized, ... (EEG) at onset usually shows focal or multifocal spike discharges and irregular focal slow activity.

Hypsarrhythmia is a brain wave pattern seen when seizures are not occurring and are indicated by chaotic, high-voltage spikes on an EEG. This pattern is present in wakefulness but is enhanced ...

Progressive encephalopathy with edema, hypsarrhythmia, and optic nerve atrophy (PEHO) syndrome was first described in 1991 by Salonen et al in the Finnish population. [] It is an apparently ...

Symptoms of IS include spasms of the limbs and trunk (extending or stiffening of the arms, legs, neck or trunk) that occur in clusters, an electroencephalography (EEG) pattern of hypsarrhythmia ...
