Hypnotizability: Emerging Perspectives and Research

Age regression in the treatment of needle phobia: a case report

Trypanophobia (needle phobia) frequently occurs because of negative encounters with medical procedures and/or needles. Trypanophobia ranges in severity from causing mild anxiety, including apprehension about medical procedures, to severe anxiety and complete avoidance of medical care. In this case report, we describe a 29-year-old who underwent hypnosis-facilitated age regression therapy to improve his trypanophobia. Through the guidance of his subconscious, he realized his reaction to needles may not have been directly related to a difficult medical procedure he had undergone at the age of two. The patient's subconscious turned his attention to the anxiety he felt from being separated from his mother at the time of the procedure.

Comparing Neural Correlates of Consciousness: From Psychedelics to Hypnosis and Meditation

BACKGROUND

Pharmacological and nonpharmacological methods of inducing altered states of consciousness (ASCs) are becoming increasingly relevant in the treatment of psychiatric disorders. While comparisons between them are often drawn, to date no study has directly compared their neural correlates.

METHODS

To address this knowledge gap, we directly compared 2 pharmacological methods (psilocybin 0.2 mg/kg orally [n = 23] and lysergic acid diethylamide [LSD] 100 μg orally [n = 25]) and 2 nonpharmacological methods (hypnosis [n = 30] and meditation [n = 29]) using resting-state functional connectivity magnetic resonance imaging and assessed the predictive value of the data using a machine learning approach.

RESULTS

We found that 1) no network reached significance in all 4 ASC methods; 2) pharmacological and nonpharmacological interventions of inducing ASCs showed distinct connectivity patterns that were predictive at the individual level; 3) hypnosis and meditation showed differences in functional connectivity when compared directly and also drove distinct differences when jointly compared with the pharmacological ASC interventions; and 4) psilocybin and LSD showed no differences in functional connectivity when directly compared with each other, but they did show distinct behavioral-neural relationships.

CONCLUSIONS

Overall, these results extend our understanding of the mechanisms of action of ASCs and highlight the importance of exploring how these effects can be leveraged in the treatment of psychiatric disorders.

Real-time assessment of hypnotic depth, using an EEG-based brain-computer interface: a preliminary study

OBJECTIVE

Hypnosis can be an effective treatment for many conditions, and there have been attempts to develop instrumental approaches to continuously monitor hypnotic state level ("depth"). However, there is no method that addresses the individual variability of electrophysiological hypnotic correlates. We explore the possibility of using an EEG-based passive brain-computer interface (pBCI) for real-time, individualised estimation of the hypnosis deepening process.

RESULTS

The wakefulness and deep hypnosis intervals were manually defined and labelled in 27 electroencephalographic (EEG) recordings obtained from eight outpatients after hypnosis sessions. Spectral analysis showed that EEG correlates of deep hypnosis were relatively stable in each patient throughout the treatment but varied between patients. Data from each first session was used to train classification models to continuously assess deep hypnosis probability in subsequent sessions. Models trained using four frequency bands (1.5-45, 1.5-8, 1.5-14, and 4-15 Hz) showed accuracy mostly exceeding 85% in a 10-fold cross-validation. Real-time classification accuracy was also acceptable, so at least one of the four bands yielded results exceeding 74% in any session. The best results averaged across all sessions were obtained using 1.5-14 and 4-15 Hz, with an accuracy of 82%. The revealed issues are also discussed.

Definition and refinement of HYlaDO, a self-hypnosis training program for chronic pain management: A qualitative exploratory study

One in four Canadians is affected by chronic pain, frequently treated with opioids, which present a risk of addiction and overdose. The development of non-pharmacological interventions is therefore crucial. In a pilot project, a self-hypnosis training program showed encouraging results in improving breast cancer patients' quality of life. Based on this program, we developed a new self-hypnosis program for chronic pain patients: HYlaDO (Hypnosis of pain in French, HYpnose de la DOuleur). To structure the process of adapting an existing program to a new context, we used the ORBIT model (Obesity-Related Behavioral Intervention Trials), which consists of four development phases. This study aimed to collect patients' opinions and recommendations, and to refine HYlaDO (ORBIT Phase Ib). Fifteen participants took part in individual semi-structured interviews about this program. Two analysts coded the verbatims, and a thematic categorization was performed. Six themes emerged: practice training, expected vs. perceived effects, chronic pain management, individual practice, satisfaction, and participants' recommendations. Improvements to be considered in this type of program were finally discussed.

Delivery of a Group Hypnosis Protocol for Managing Chronic Pain in Outpatient Integrative Medicine

Although strong evidence exists for using individual hypnosis to treat pain, evidence regarding group applications is limited. This project evaluated changes in multiple outcome measures in persons with chronic pain treated with 8 weeks of group hypnosis. Eighty-five adults with diverse chronic pain etiologies completed an 8-session, structured group hypnosis treatment. Pain intensity, pain interference, and global health were evaluated at baseline, posttreatment, and 3- and 6-months posttreatment. Linear mixed effects models assessed changes in outcomes over time. In a model testing, all three outcome measures simultaneously, participants improved substantially from pre- to posttreatment and maintained improvement across follow-up. Analyses of individual outcomes showed significant pre- to posttreatment reductions in pain intensity and interference, which were maintained for pain intensity and continued to improve for pain interference across follow-up. The findings provide compelling preliminary evidence that a group format is an effective delivery system for teaching individual skills in using hypnosis for chronic pain management. Larger randomized controlled trials are warranted to demonstrate equivalence of outcomes between treatment modes.

Update on hypnotherapy for psychiatrists

Although hypnosis has played a part in psychotherapy for a long time, it is not yet seen as an evidence-based therapy and is absent from many practice guidelines when it comes to the treatment of psychiatric disorders. At present, the applications and methods of hypnotherapy are poorly understood and other methods of psychotherapy tend to be favoured. This review article aims to introduce the role of hypnotherapy and its application for certain common psychiatric presentations, as well as examine its efficacy by summarising recent evidence from high-quality outcome studies and meta-analyses.
