[Prolonged confused seizure state of frontal origin in an aged patient].

The authors discuss the case of a man who, at the age of 63, presented episodes of prolonged confusional state de novo. The EEG recordings showed the existence of an electrical status with widespread spikes and polyspike-and-waves of the "absence status." Further recordings showed a focal onset of one of the episodes of prolonged confusional state. The electric and clinical characteristics of this observation indicate that a frontal localisation with secondary generalization of the discharge is probable. This electro-clinical picture is compared to other literature on the subject and its nosological specificity is discussed.
