Prolonged epileptic twilight states

Abstract
Confusion, speech arrest, automatic behavior and amnesia characterized the prolonged twilight states of petit mal and psychomotor status [in man]. In psychomotor status 2 electroclinical phases were differentiated; a continuous twilight state with partial responsiveness and reactive automatisms interrupted by staring, total loss of responsiveness and stereotyped automatisms. During the 1st phase, with reactive behavior, the EEG showed bilateral diffuse slowing. During the 2nd phase, with stereotyped automatisms, there were spreading right temporal 4-12 Hz discharges. Petit malstatus had 1 continuous twilight state, during which stereotyped and reactive automatisms merged as 1.504 Hz spike-wave complexes, and bimedial temporal 4 Hz discharges appeared in the EEG.
