Abstract
Epileptic seizures are characterized by a multifaceted spectrum of alterations in the general level of awareness and/or the subjective contents of consciousness. Complete loss of consciousness occurs when epileptic activity involves both cortical and subcortical structures, as in generalized seizures. On the other hand, simple partial seizures can spare both the level and contents of consciousness. Finally, complex partial seizures associated with medial temporal lobe discharges can selectively impair the patient's subjective experiences with variable degrees of responsiveness. The differences in ictal semiology between patients with epilepsy offer unique avenues for understanding the relationship between pathological brain function and altered conscious states.
