Pseudo-epileptic seizures: hypnosis as a diagnostic tool

Area of Science:

• Neurology
• Psychiatry
• Psychosomatic Medicine

Background:

• Pseudo-epileptic seizures (PES) are often characterized by dissociative features and amnesia.
• Distinguishing PES from epileptic seizures (ES) can be challenging, impacting treatment.
• Hypnosis offers a potential tool to explore psychogenic influences in seizure disorders.

Purpose of the Study:

• To investigate the efficacy of hypnosis in identifying a psychogenic component in pseudo-epileptic seizures.
• To explore differences in hypnotizability between patients with pseudo-epileptic seizures and epileptic seizures.

Main Methods:

• A pilot study utilizing hypnosis to reverse amnesia associated with seizures.
• Semi-blind referral of cases for diagnosis validation using electro-encephalic corroboration.
• Measurement of hypnotizability in patients diagnosed with epileptic seizures and pseudo-epileptic seizures.

Main Results:

• The experimental diagnosis using hypnosis corresponded with the clinical diagnosis in 8 out of 9 evaluable patients.
• Patients with pseudo-epileptic seizures demonstrated significantly higher responsiveness to hypnosis compared to patients with epileptic seizures.
• Hypnotizability measurements supported the hypothesis of greater suggestibility in PES.

Conclusions:

• Hypnosis is a viable method for detecting psychogenic elements in pseudo-epileptic seizures.
• The findings suggest a neurophysiological basis for the dissociative nature of PES, linked to hypnotizability.
• Further research is warranted to integrate hypnosis into the diagnostic and therapeutic protocols for seizure disorders.
