The electroencephalogram during spontaneous night sleep in epileptic patients

O eletrencefalograma durante o sono noturno espontâneo em pacientes epilépticos

Abstracts

The sleep sistem results of the activity of two components: a descending component originated in the limbic structures, and an ascending system involving the bulbopontine structures which receives projections from the spinal cord components. Although the neocortex is not necessary for sleep mechanisms, it plays a very important role in sleep. Therefore, during the sleep state there is no significant quantitative difference in brain activity, but qualitative changes are recorded in EEG of epileptics patients during all night sleep.


Foram estudados os traçados eletrencefalográficos obtidos durante o sono noturno de 5 pacientes epilépticos. Os resultados demonstram que a atividade paroxística focal evidencia modificações tanto qualitativas como quantitativas quando registrada no l.° e 2.° estágios do sono. Por outro lado, o EEG com descargas difusas e bilaterais intensas na fase inicial do sono, apresenta ausência de paroxismo na fase paradoxal. Assim, a análise dos diversos estágios do sono evidencia diferenças qualitativas e quantitativas na atividade elétrica cerebral de pacientes epilépticos durante o sono noturno.

SUMMARY

The sleep sistem results of the activity of two components: a descending component originated in the limbic structures, and an ascending system involving the bulbopontine structures which receives projections from the spinal cord components. Although the neocortex is not necessary for sleep mechanisms, it plays a very important role in sleep. Therefore, during the sleep state there is no significant quantitative difference in brain activity, but qualitative changes are recorded in EEG of epileptics patients during all night sleep.

RESUMO

Foram estudados os traçados eletrencefalográficos obtidos durante o sono noturno de 5 pacientes epilépticos. Os resultados demonstram que a atividade paroxística focal evidencia modificações tanto qualitativas como quantitativas quando registrada no l.° e 2.° estágios do sono. Por outro lado, o EEG com descargas difusas e bilaterais intensas na fase inicial do sono, apresenta ausência de paroxismo na fase paradoxal. Assim, a análise dos diversos estágios do sono evidencia diferenças qualitativas e quantitativas na atividade elétrica cerebral de pacientes epilépticos durante o sono noturno.
