Autosuggestion: a cognitive process that empowers your brain?

Autosuggestion is a cognitive process that is believed to enable control over one's own cognitive and physiological states. Despite its potential importance for basic science and clinical applications, such as in rehabilitation, stress reduction, or pain therapy, the neurocognitive mechanisms and psychological concepts that underlie autosuggestion are poorly defined. Here, by reviewing empirical data on autosuggestion and related phenomena such as mental imagery, mental simulation, and suggestion, we offer a neurocognitive concept of autosuggestion. We argue that autosuggestion is characterized by three major factors: reinstantiation, reiteration, and volitional, active control over one's own physiological states. We also propose that autosuggestion might involve the 'overwriting' of existing predictions or brain states that expect the most common (but not desired) outcome. We discuss potential experimental paradigms that could be used to study autosuggestion in the future, and discuss the strengths and weaknesses of current evidence. This review provides a first overview on how to define, experimentally induce, and study autosuggestion, which may facilitate its use in basic science and clinical practice.

Therapeutic Use of the Elkins Hypnotizability Scale: A Feasibility Study.

Hypnotizability assessment can inform hypnotic interventions, and studies on brief hypnotic inductions suggest that it may also confer therapeutic benefits. However, hypnotizability is rarely assessed in clinical practice due to limitations of current measures. The Elkins Hypnotizability Scale (EHS) improved upon such limitations and has been shown to be a very reliable and valid hypnotizability measure. This is the first study to examine the feasibility of the EHS as a therapeutic measure. Fifty-five participants were administered the EHS and randomized to two weeks of self-hypnosis with or without a recording. Results indicated that relaxation increased immediately after EHS administration, and relaxation and psychological distress improved after two weeks of self-hypnosis with the EHS induction. These results suggest that the EHS may be considered as a therapeutic measure and an avenue to introduce self-hypnosis in clinical practice with or without audio recordings.

Hypnotizability and the Natural Human Ability to Alter Experience.

There seems to be a natural, human ability to alter one's experience that already exists - prior to and apart from any hypnotic induction. Individual differences in this ability range from low to high and are largely commensurate with the person's assessed hypnotizability. More importantly, these preexisting, individual differences in the ability to alter experience seem to be the "substrate" that enables each individual's response to hypnotic suggestions. It is proposed that, with some notable exceptions, the hypnosis field's understanding of hypnotizability has been hindered by theorists' (and clinicians') tendency to consider the instruments that reveal hypnotic phenomena (i.e., hypnosis and suggestions) to be explanatory concepts.

Efficacy of Self-hypnosis on Quality of Life For Children with Chronic Pain Syndrome.

The aim of this study was to assess the efficacy of self-hypnosis in a therapeutic education program (TEP) for the management of chronic pain in 26 children aged 7 to 17 years. Outcomes of the study were a total or a partial (at least 1) achievement of the therapeutic goals (pain, quality of sleeping, schooling, and functional activity). Sixteen patients decreased their pain intensity, 10 reached all of their therapeutic goals, and 9 reached them partially. Self-hypnosis was the only component of the TEP associated with these improvements. The current study supports the efficacy of self-hypnosis in our TEP program for chronic pain management in children.

Future-Focused Therapeutic Strategies for Integrative Health.

For many years, the therapy field was dominated by a focus on the past. In this context, many clinicians were trained to use hypnosis as a tool to explore the past, and there is a rich literature documenting the use of hypnosis as a tool to induce age regression and the uncovering of traumatic memories. This article presents a therapeutic paradigm that focuses on the future. Hypnosis is used to induce creativity, flexibility, and openness to the future. In the context of health care, hypnosis is used to explore the best possible treatment outcome, which may be pharmacological, surgical, or a combination of both as well as other nonsurgical interventions. This article elaborates on the effective use of a therapeutic hypnosis strategy and technique focused on the future.

The role of autosuggestion in geriatric patients' quality of life: a study on psycho-neuro-endocrine-immunology pathway.

BACKGROUND: There has been no study conducted about the effect of autosuggestion on quality of life for geriatric patients. Our aim was to evaluate the efficacy of autosuggestion for geriatric patients' quality of life and its impact on psycho-neuro-endocrine-immune pathway. METHODS: Sixty geriatric patients aged ≥60 years in a ward were randomly assigned to either receive autosuggestion or not. Autosuggestion was recorded in a tape to be heard daily for 30 days. Both groups received the standard medical therapy. Primary outcome was quality of life by COOP chart. Secondary outcomes were serum cortisol level, interleukin-2, interleukin-6, interferon-γ, and N-acetylaspartate/creatine ratio in limbic/paralimbic system by magnetic resonance spectroscopy. The study was single blinded due to the nature of the intervention studied. RESULTS: Out of 60 subjects, 51 finished the study. The autosuggestion group reported better scores than the control one for quality of life, COOP chart 1.95 vs. 2.22 (95% CI, p = 0.02). There were increments of serum cortisol (p = 0.03) and interleukin-6 in the autosuggestion group (p = 0.04). Interleukin-2, interferon-γ, and N-acetylaspartate/creatine ratio in prefrontal cortex showed a tendency to increase in the autosuggestion groups. CONCLUSION: Autosuggestion is associated with improvement of geriatrics' quality of life, serum cortisol level, and adaptive immunity. There is a better trend for neuroplasticity in prefrontal cortex in the autosuggestion group.

When Children are the Least Vulnerable to False Memories: A True Report or a Case of Autosuggestion?

In this case report, a legal case revolving around the reliability of statements given by a 6-year-old girl is described. She claimed to have witnessed her mother being murdered by her father. Two psychological experts provided diametrically opposed opinions about the reliability of her statements. One expert, a clinician, opined that the girl's statements were based on autosuggestion whereas the other expert, a memory researcher, stated that autosuggestion was unlikely to have played a role. This case and the analysis of the experts' opinions illustrate what may happen when experts in court are unaware of the recent literature on (false) memory. That is, recent studies show that autosuggestion is less likely to occur in young children than in older children and adults. The current case stresses the importance and implications of relying on memory experts in cases concerning the reliability of eyewitness statements.

Subjective hypnotic efficacy of Trazodone and Mirtazapine in patients with chronic insomnia: a retrospective, comparative study.

OBJECTIVE: To compare the efficacy of two sedating antidepressants, trazodone and mirtazapine, for the treatment of chronic insomnia. DESIGN: Retrospective cross-sectional study. Patients received trazodone or mirtazapine for at least three months at the dosage that was effective in the titration period. MATERIAL AND METHODS: 150 patients with chronic insomnia, referred to the Sleep Disorder Center of Bari, diagnosed as chronic insomniacs according to ICSD-3 diagnostic criteria, with or without dysthymic disorder according to DSM V diagnostic criteria, and treated with trazodone or mirtazapine were retrospectively chart-reviewed. 79 patients satisfying inclusion criteria were enrolled: 33 had been treated with trazodone (12 males and 21 females aged 36 to 77 years, mean age 63.57+10.38 years; 18 with psychophysiological insomnia and 15 with insomnia associated with dysthymic disorder) and 46 with mirtazapine (26 males and 20 females aged 25 to 86 years, mean age 60.04+16.67 years; 25 with psychophysiological insomnia and 21 with insomnia comorbid with dysthymic disorder). The patients were considered responsive to the treatment when they no longer met the criteria for insomnia at the end of the maintenance period. RESULTS: Both drugs were efficacious in more than 60% without any difference in the proportion of responders between the two medication groups (87.87% in the trazodone group versus 86.95% in the mirtazapine group; p=0.26 and regardless of sex, age and possible association of insomnia with depression). The minimum dosages used for both drugs (25 mg for trazodone and 7.5 mg for mirtazapine) corresponded to the highest percentage of responders in the groups treated successfully with either trazodone (37.93%) or mirtazapine (52.5%). For each medication group, subgroup analysis revealed higher statistically significant rates of responders in patients with lower final dosage (25 to 75 mg for trazodone and 7.5 to 15 mg for mirtazapine) than in those with higher final dosage (100 to 150 mg for trazodone and 15 to 30 mg for mirtazapine) (100% versus 42.85%; p<0.001 in the trazodone group and 100% versus 53.84%; p<0.001 in mirtazapine group) Conclusion. On a long term basis trazodone administration appeared as effective and well tolerated as mirtazapine in the treatment of chronic insomnia regardless of its association with dysthymia. Both medications resulted efficacious at very low doses and had a sustained efficacy, likely without problems of tolerance.

Los prodigios del hombre encarnado. Víctor Melcior y la redefinición de la mediumnidad (1901) / The marvels of the incarnated man. Víctor Melcior and the redefinition of mediumship (1901)

A finales del siglo XIX, mediante el estudio científico de los fenómenos espiritistas, nuevos enfoques médicos y psicológicos se aplicaron a la mediumnidad. La idea del médium espiritista fue sustituida por la noción del médium como un ser desequilibrado, capaz de emanar fuerzas psíquicas inconscientemente. Este trabajo analiza la redefinición de la mediumnidad a través de unos polémicos artículos del médico catalán Víctor Melcior. Esta microhistoria sirve, por un lado, para situar el debate local dentro del contexto científico internacional y, así, mostrar las relaciones entre el espiritismo, la medicina y la psicopatología del momento. Por otro lado, permite analizar las reacciones de algunos espiritistas a las teorías de Melcior, así como las consecuencias que este debate tuvo para el espiritismo en general (AU)

Towards the end of the 19th century, new medico-psychological approaches were applied to mediumship through the scientific study of spiritualist phenomena. The spiritualist idea of the medium was replaced with the notion of the medium as an unstable human being capable of emanating psychic forces unconsciously. This paper analyses the redefinition of mediumship through the polemical articles of the Catalan physician Víctor Melcior. On one hand, this microhistory allows the local debate to be placed within the scientific international context, describing the relationships among spiritualism, medicine and psychopathology at that time. On the other hand, it permits analysis of the reactions of some spiritualists to Melciors (AU)

A cross-validation of two differing measures of hypnotic depth.

Several sets of regression analyses were completed, attempting to predict 2 measures of hypnotic depth: the self-reported hypnotic depth score and hypnoidal state score from variables of the Phenomenology of Consciousness Inventory: Hypnotic Assessment Procedure (PCI-HAP). When attempting to predict self-reported hypnotic depth, an R of .78 with Study 1 participants shrank to an r of .72 with Study 2 participants, suggesting mild shrinkage for this more attributional measure of hypnotic depth. Attempting to predict hypnoidal state (an estimate of trance) using the same procedure, yielded an R of .56, that upon cross-validation shrank to an r of .48. These and other results suggest that, although there is some variance in common, the self-reported hypnotic depth score appears to be tapping a different construct from the hypnoidal state score.

The placebo effect: how the subconscious fits in.

The placebo effect is very well known, being replicated in many scientific studies. At the same time, its exact mechanisms still remain unknown. Quite a few hypothetical explanations for the placebo effect have been suggested, including faith, belief, hope, classical conditioning, conscious/subconscious expectation, endorphins, and the meaning response. This article argues that all these explanations may boil down to autosuggestion, in the sense of "communication with the subconscious." An important implication of this is that the placebo effect can in principle be used effectively without the placebo itself, through a direct use of autosuggestion. The benefits of such a strategy are clear: fewer side effects from medications, huge cost savings, no deception of patients, relief of burden on the physician's time, and healing in domains where medication or other therapies are problematic.

Hypnotically assisted diaphragmatic exercises in the treatment of stuttering: a preliminary investigation.

This preliminary study investigates the combined effect of intensive hypnotherapy and diaphragmatic exercises in the management of stuttering. Fifty-nine clients with stuttering were trained to practice abdominal weightlifting to strengthen their respiratory muscles and to improve their diaphragmatic movements. The weightlifting exercises involved lifting a dumbbell (2.0-4.0 kg) with the abdomen for 2 hours daily for 8 consecutive days. Hypnotherapy was utilized to alleviate anxiety, to boost self-confidence, and to increase motivation for weightlifting exercise. The pre- and postmeasures were statistically significant (p < .001). Results of the study provide support for the effectiveness of hypnotically assisted diaphragmatic training in the management of stuttering but should be further studied in controlled trials.

[Possibilities of hypnosis and hypnosuggestive methods in oncology]. / A hipnózis és a hipnoszuggesztív módszerek lehetoségei az onkológiában.

Fear of death, pain, or the recurrence of the illness of tumor patients can narrow their attention to a point where a spontaneous altered state of consciousness occurs. In these cases hypnosis either in formal psychotherapy or embedded into the everyday communication with the physician can effectively complement other already known medical and psychological techniques. Although numerous studies have reported the beneficial physical and mental changes induced by hypnosis, for a long time there were not enough research to affect evidence-based medicine. New studies meeting the most rigorous methodological standards, new reviews and the characteristics of hypnosis shown by neuroimaging techniques support the acceptance of this method. Hypnosis is used and studied with adult and child tumor patients alike mostly in the areas of anxiety, pain, nausea, vomiting, quality of life, mood amelioration, immune system and hot flushes. Most of the assays describe hypnosis as an empirically validated treatment technique that in most cases surpass attention diversion, coping trainings, cognitive behavior and relaxation techniques and other regular treatments. In this paper we review these observations.

Autogenic training alters cerebral activation patterns in fMRI.

Cerebral activation patterns during the first three auto-suggestive phases of autogenic training (AT) were investigated in relation to perceived experiences. Nineteen volunteers trained in AT and 19 controls were studied with fMRI during the first steps of autogenic training. FMRI revealed activation of the left postcentral areas during AT in those with experience in AT, which also correlated with the level of AT experience. Activation of prefrontal and insular cortex was significantly higher in the group with experience in AT while insular activation was correlated with number years of simple relaxation exercises. Specific activation in subjects experienced in AT may represent a training effect. Furthermore, the correlation of insular activation suggests that these subjects are different from untrained subjects in emotional processing or self-awareness.

Cajal's brief experimentation with hypnotic suggestion.

Spanish histologist Santiago Ramón y Cajal, one of the most notable figures in Neuroscience, and winner, along with Camillo Golgi, of the 1906 Nobel Prize in Physiology or Medicine for his discoveries on the structure of the nervous system, did not escape experimenting with some of the psychiatric techniques available at the time, mainly hypnotic suggestion, albeit briefly. While a physician in his thirties, Cajal published a short article under the title, "Pains of labour considerably attenuated by hypnotic suggestion" in Gaceta Médica Catalana. That study may be Cajal's only documented case in the field of experimental psychology. We here provide an English translation of the original Spanish text, placing it historically within Cajal's involvement with some of the key scientific and philosophical issues at the time.

[Psychotherapy and pain]. / Psychotherapie und Schmerz mit besonderer Berücksichtigung der Hypnosetherapie.

In "Integrated psychotherapy" we indicate necessity of combining psychotherapy with all other psychotherapeutic and medical methods (drugs, physiotherapy, etc.) in order to obtain best result. We distinguish between "professional" and "basic" psychotherapy. The latter also has effect on mood and by it on health for patients. Furthermore it is an important facilitating means for a special psychotherapy. We emphasize to teach this in systematic professional education as well for doctors as for all social professions.
