Rolandic Spikes in Children with and without Epilepsy (20 Subjects Polygraphically Studied During Sleep)

Abstract

The authors polygraphically studied the nocturnal sleep of 20 neurologically normal children with typical centrotemporal spikes. The children were divided into two groups: (A) 10 children with centrotemporal spikes and benign epilepsy; and (B) 10 children with centrotemporal spikes without epilepsy. The mean age when the average period of sleep record was performed was the same for the two groups, 8.5 years. The cyclic organization of sleep and the percentages of the different stages were normal in all 20 subjects. The number of spikes was counted in all the subjects during wakefulness and during different stages of sleep. All subjects of both groups showed an important increase in the frequency of spikes going from drowsiness until slow sleep; on the other hand, the activity remained high during REM sleep only for subjects of Group A. Other differences between the two groups concerned the appearnce during sleep of generalized spike waves and independent Rolandic spikes. The authors conclude with the affirmation that the polygraphic study of nocturnal sleep in children with Rolandic spikes can be an additional parameter for differential diagnosis between children with and those without epilepsy.

Correlation of sleep macrostructure parameters and idiopathic epilepsies

“…Terzano et al 13 and Dalla Bernardina and Beghini 14 did not find changes in the sleep of their patients with BECTS. The only alteration found by BaldyMoulinier 15 was an increased latency for REM sleep that we did not detect in our patients.…”

Benign rolandic epilepsy: clinical and electroencephalographic correlates

“…Despite the paucity of publications specifically proposing parameters of electrographic benignity for BRE cases, same parameters, such as morphology of rolandic spikes, exact location of paroxysms, prognostic value of generalized paroxysms, relation between the intensity of rolandic spikes and level of consciousness, polysomnographic evaluations, "double spike phenomenon," and studies with brain mapping, were already tested in an attempt to predict the clinical evolution of specific cases [33][34][35][36] .…”

Eplepsia benigna da infância com pontas centrotemporais: foco central alto ou baixo

“…A maioria dos indivíduos que apresentavam localização da máxima negatividade das pontas nas regiões centrais altas (C3, C4) exibia também atividade epileptiforme focal diferente da centrotemporal, em contraposição à baixa incidência deste achado nos indiví-duos que apresentavam a localização da máxima negatividade das pontas nas regiões centrais baixas (C5, C6) ou temporais médias. É descrita na literatura a presença de atividade epileptiforme focal não centrotemporal, localizada principalmente nas regiões occipitais e parietais, associada à atividade epileptiforme centrotemporal em pacientes com EBICT 3,10,11,[15][16][17][18][19][20] . No presente estudo, atividade epileptiforme focal independente da centrotemporal -localizada nas regiões occipitais e/ou parietais -foi observada em 20% dos casos, percentual idêntico ao assinalado por Dalla Bernardina & Beghini 16 .…”

Não foram observadas, na presente casuística, características clínico-eletrencefalográficas divergentes da EBICT nas crianças com atividade epileptiforme focal não centrotemporal em acordo com várias publicações 2,14,[16][17][18][19][20][21] .…”
