Hypnotic induction of an epileptic seizure: A brief communication

Abstract

This case study investigated the utility of hypnosis to precipitate a seizure in a patient with refractory epilepsy. The patient was twice administered a hypnotic induction and a suggestion to age regress to a day when he was distressed and suffered repeated seizures. The patient did not respond to the first hypnotic suggestion; however, an epileptic seizure was observed in the second hypnotic session. Videorecording and subdural electroencephalograph recording confirmed that he suffered an epileptic seizure. Postexperimental inquiry revealed that the patient used deliberate cognitive strategies to avoid seizure onset in the first session but adopted a more constructive cognitive style in the second session. Findings are discussed in terms of emotions, hypnosis, and cognitive style as mediating factors in the experimental precipitation of epileptic seizures
