Is hypnotic assessment relevant to neurology?

Area of Science:

• Neuroscience
• Psychology
• Medical Hypnotherapy

Background:

• Hypnotic susceptibility varies among individuals, linked to functional equivalence (FE) between imagery and perception/action, cortical excitability, and information processing.
• Physiological differences in individuals with high, medium, and low hypnotizability scores are evident even outside hypnotic states.
• The application of hypnotic assessment in neurological diseases remains underexplored.

Purpose of the Study:

• To review hypnotizability-related features.
• To explore the hypothesis that enhanced FE, distinct information processing, and pain/immune system control in medium-to-high hypnotizability individuals have neurological applications.
• To discuss the feasibility and potential of hypnotic assessment in clinical settings for neurological conditions.

Main Methods:

• Review of existing studies on hypnotic susceptibility and associated physiological and cognitive differences.
• Analysis of functional equivalence (FE) between imagery and perception/action.
• Discussion of information processing modes and self-regulation of pain and immune responses in relation to hypnotizability.

Main Results:

• Individuals with varying hypnotic susceptibility exhibit differences in FE, cortical excitability, and information processing.
• Medium-to-high hypnotizability is associated with stronger FE, unique information processing, and greater capacity for pain and immune system control.
• Current evidence for hypnotic treatments in neurological diseases is inconsistent due to methodological limitations in clinical trials.

Conclusions:

• Hypnotizability is linked to distinct neurophysiological and cognitive profiles.
• Features associated with medium-to-high hypnotizability suggest potential therapeutic applications in neurology.
• Hypnotic assessment could be a valuable tool for guiding treatment and rehabilitation in neurological diseases.
