Abstract

12 All night polygraphic records of 11 patients with petit mal (PM) epilepsy were analyzed. PM seizures appeared in the transitional periods from wake state towards sleep, during transient awakening and in the transitional periods to and from rapid sleep. Detailed analysis of the transitional periods by examination of the dynamics of 4 levels of vigilance in every 20 sec, showed that PM absences occur after a fluctuation of the vigilance level and there is an optimum band of slightly depressed vigilance passing through which, especially in the direction from a more superficial to a deeper state, facilitates the occurrence of PM absences.
