Hypnosis as therapy for functional neurologic disorders

Area of Science:

• Psychology
• Neurology
• Medical History

Background:

• Suggestion, the intentional communication of beliefs or ideas, has been integral to healing practices since the 19th century.
• Hypnosis evolved from earlier practices like animal magnetism and ritual healing, incorporating the concept of suggestion.
• Functional neurologic symptoms have historically been addressed using various suggestive techniques within hypnosis.

Purpose of the Study:

• To trace the historical application of suggestion in hypnosis for functional neurologic symptoms.
• To examine the evolution of suggestive techniques from historical practices to modern therapeutic contexts.
• To highlight the role of suggestion in influencing patient expectancies and symptom trajectories.

Main Methods:

• Historical analysis of therapeutic practices involving suggestion and hypnosis.
• Review of 19th-century and modern approaches to treating functional neurologic symptoms with suggestion.
• Examination of the integration of suggestion within contemporary therapeutic modalities.

Main Results:

• Suggestion has been consistently applied to functional and dissociative neurologic symptoms for centuries.
• Therapeutic use of suggestion in hypnosis declined in the early 20th century but has seen a resurgence.
• Current applications often embed suggestion within cognitive-behavioral, rehabilitative, or psychodynamic therapies.

Conclusions:

• Suggestion, with or without hypnosis, remains a relevant component in managing functional neurologic symptoms.
• The efficacy of suggestion is influenced by clinical interactions and patient expectancies.
• Further research, including randomized controlled trials, is needed to fully evaluate suggestion's role in complex treatment interventions.
