[Clinico-electroencephalographic analysis of wakeful epilepsy and sleep epilepsy].

Some results of a clinico-physiological analysis of epileptic patients with a different diurnal distribution of generalized convulsive seizures in the sleep-vigilance cycle are reported. It is demonstrated that in vigilant epilepsy there is an intensification of L-rhythms in the EEG recordings in the different functional states of vigilance, combined with a prevalence of delta-sleep in the sleep structure. In sleep epilepsy there is a predominance of the 2nd sleep stage in the sleep structure, besides an EEG desynchronization in the state of vigilance. These results indicate some differences in the activity of nonspecific (synchronizing and desynchronizing) structures in epilepsy with a different diurnal distribution of generilized convulsive seizures.
