Summary

This study reports two cases of hypnotic sequelae in a research setting. One participant experienced amnesia, while another had a potential psychogenic seizure, highlighting risks of hypnosis research.

Area of Science:

Psychology
Neuroscience

Background:

Hypnotic sequelae are adverse events that can occur following hypnosis.
Research on hypnosis in non-clinical populations requires careful consideration of potential risks.

Observation:

Case 1: A male participant experienced retroactive amnesia after hypnosis, unable to recall familiar information despite being fully awake.
Case 2: A female participant with a history of epilepsy experienced a seizure during hypnosis, suspected to be psychogenic.

Findings:

Hypnotic sequelae, such as amnesia and psychogenic seizures, can occur even in non-clinical research settings.
Pre-existing psychological conflicts and specific hypnotic scripting may contribute to adverse events.

Implications:

These cases underscore the importance of thorough screening and risk management in hypnosis research.
Further investigation into the mechanisms underlying hypnotic sequelae is warranted to ensure participant safety.
