Epileptic seizures and pseudoseizures from the viewpoint of the hierarchy of consciousness

Epileptic seizures and pseudoseizures in temporal lobe epilepsies were studied from the viewpoint of the hierarchy of consciousness. Twenty-two patients with temporal lobe epilepsies (TLE) who showed true amnesia or impairment of consciousness developing from the dreamy state, even though their actions and movement continued, were selected among 160 patients with TLE. nine patients with manifested pseudo seizures, pseudoseizure status, and complex partial seizure status (CPSE) were investigated. Twelve patients in whom impairment of consciousness followed the dreamy state recognized their own existence and maintained some self-directed consciousness. The other 10 patients with amnesia were aware of their goals. Furthermore, pseudostatus ranged from epileptic seizures during pseudoseizure status to pseudoseizures during status epilepticus (SE). In some cases of CPS, awareness and self-directed consciousness were only partially pseudoseizures, disorders of self-directed consciousness are assumed to influence awareness and arousal.
