Changes in brain activity have been found in some studies of highly responsive hypnotic subjects. These changes vary depending upon the type of suggestions being given. The state of light to medium hypnosis, where the body undergoes physical and mental relaxation, is associated with a pattern mostly of alpha waves However, what these results indicate is unclear. They may indicate that suggestions genuinely produce changes in perception or experience that are not simply a result of imagination. However, in normal circumstances without hypnosis, the brain regions associated with motion detection are activated both when motion is seen and when motion is imagined, without any changes in the subjects' perception or experience. This may therefore indicate that highly suggestible hypnotic subjects are simply activating to a greater extent the areas of the brain used in imagination, without real perceptual changes. It is, however, premature to claim that hypnosis and meditation are mediated by similar brain systems and neural mechanisms.
The following person had completed years of graduate school plus substantial hypnotherapy training at various schools before he took our 200-hour program in 2013. He was so impressed that he returned in 2015 and took our training again. Here's his response after completing that. Since he wrote this, he completed our graduate clinical courses twice plus our hypnotherapy training a 3rd time, and is planning to take our training for a 4th time in 2019!
The weird thing is I was a really shy kid, and would never act like a moron or do embarrassing stuff (like he has us do) in front of my whole school - WILLINGLY! But I DID! I remember feeling really calm, and confident and WANTED to put on a fun show for the school. It felt like the audience was cloudy and obscured by a fog and I just felt so calm and zen like in a trance - but totally aware and intentionally playing along. The last thing he has us do at the end of the event was ask for a signature from anyone we met, believing they were a celebrity (we were instructed to have them sign our hands). I remember people's expressions, they thought we were insane, but i felt empowered by being able to convince others that I was hypnotized - like they were being laughed at not me.
Barber et al. noted that similar factors appeared to mediate the response both to hypnotism and to cognitive behavioural therapy, in particular systematic desensitization. Hence, research and clinical practice inspired by their interpretation has led to growing interest in the relationship between hypnotherapy and cognitive behavioural therapy.:105
Cognitive behavioural hypnotherapy (CBH) is an integrated psychological therapy employing clinical hypnosis and cognitive behavioural therapy (CBT). The use of CBT in conjunction with hypnotherapy may result in greater treatment effectiveness. A meta-analysis of eight different researches revealed "a 70% greater improvement" for patients undergoing an integrated treatment to those using CBT only.
Look for a hypnotherapist who is a member of the American Society of Clinical Hypnosis (ASCH) or the Society for Clinical and Experimental Hypnosis. To be a member of either of these organizations, a hypnotherapist must have a doctorate level degree in medicine, dentistry, or psychology, or a master’s degree in nursing, social work, psychology, or marital/family therapy plus a specific number of hours of approved training in hypnotherapy. In some cases, accredited, doctoral-level practitioners of alternative health care, such traditional Chinese medicine, may also be approved for membership. Of course, in addition to looking at qualifications, you should also find a hypnotherapist with whom you feel confident and comfortable in a therapeutic relationship.
