A comparison between averaged spikes and individual visually-analyzed spikes in rolandic epileptiform discharges.

PURPOSE This study compared some morphological features of individual rolandic epileptiform discharges, used to obtain an averaged estimate, with those of the resulting estimate. METHOD Twenty-four averaged discharges from EEGs of 24 children showing rolandic spikes were compared with 480 individual discharges used in the averaging. The analysis was based on the occurrence of tangential dipol...

Remission of Benign Epilepsy with Rolandic Spikes

Purpose. The neuronal mechanisms of remission of epilepsy are not known. Based on the principles of the "network theory of epilepsy" we postulated the existence of abnormal cortico-cortical interactions at the onset of epilepsy (Hypothesis-1), and postulated that remission is associated with the decrease or disappearance of the abnormal quantitative EEG findings (Hypothesis-2). Methods. Four ch...

High resolution spatio-temporal EEG-MEG analysis of rolandic spikes.

Using high resolution EEG and MEG and a realistic volume conductor model, the authors investigated spatio-temporal aspects of the sources of spikes in children with benign rolandic epilepsy. A 64-channel EEG and simultaneous 151-channel MEG of interictal spike activity in five children all having general and/or focal seizures were recorded. A spatio-temporal multiple signal classification (MUSI...

Children with Rolandic spikes and ictal vomiting: Rolandic epilepsy or Panayiotopoulos syndrome?

Centrotemporal spikes are the EEG marker of Rolandic epilepsy, while ictus emeticus is one of the main seizure manifestations of Panayiotopoulos syndrome. Ictus emeticus has not been reported in Rolandic epilepsy. Out of a population of 1340 children with focal afebrile seizures we studied 24 children who had emetic manifestations in at least one seizure and centrotemporal spikes in at least on...
