29. Hypnosis

This chapter will cover the following topics:

I have chosen to include a section on hypnosis in this section about CAM although it is used by many conventional practitioners. They include doctors, dentists, clinical psychologists and possibly specialist nurses.

History of Hypnosis

Hypnosis has been associated with sorcery, magic and mysticism over the centuries. In ancient rituals, people may have worked themselves into a hypnotic trance.1The Oracle of Delphi who went into the cave before coming out to prophesy, had probably been inhaling volcanic gases from the cave and this contributed to her psychological state. Hence it is not really hypnosis but more like glue-sniffing.

The first study of hypnosis is usually attributed to 2Franz Mesmer who was a German physician who used hypnosis in the treatment of patients in Vienna and Paris in the late 18th century. Mesmer believed that hypnotism made use of an occult force which he termed “animal magnetism”, that flowed through the hypnotist into the subject. He was soon discredited but his technique was called mesmerism and so his name survives.

It was used, but not really understood, until the middle of the 19th century, when the English physician 3James Braid studied the phenomenon. He coined the terms hypnotism and hypnosis, after Hypnos, the Greek god of sleep. Sigmund Freud used the technique “to help neurotics recall disturbing events that they had apparently forgotten” but he abandoned it is favour of free association.

Hypnosis has been used over the years both in the clinical environment and as a stage show. The latter is undesirable, both because it often humiliates its subjects and because it can have quite profound effects on the recipient.

Background to Hypnosis

The Encyclopaedia Britannica defines 4Hypnosis as, “a special psychological state with certain physiological attributes, resembling sleep only superficially and marked by a functioning of the individual at a level of awareness other than the ordinary conscious state. This state is characterized by a degree of increased receptiveness and responsiveness in which inner experiential perceptions are given as much significance as is generally given only to external reality.”

Arachnophobia or fear of spiders is common

There are many different ways to perform hypnosis. It is not really a state of deep sleep but deep relaxation. In this state the patient concentrates entirely on the hypnotist’s voice. The therapist can suggest ideas, concepts and changes and these are firmly implanted in the patient’s mind.

Needle phobia can be overcome

It has been suggested that hypnosis works by altering the state of consciousness so that the analytical left side of the brain is subdued whilst the right side is made more alert. There is some evidence for this from techniques known as “functional neuro-imaging”.5How psychotherapy changes the brain Most of the literature about hypnosis concentrates on outcomes rather than the theoretical basis.

Hypnosis has been described as a self-induced placebo. That is not a pejorative statement. The person enables the very real benefits of placebo to take control so that pain or anxiety is tolerable.

Evidence about Hypnosis

Fear of dentists leads to tooth decay and poor general health

There are a great many papers on hypnosis and a PubMed search on that term alone produced more than 14,000 results. More than 1,500 were reviews. These numbers can be trimmed considerably by adding a condition to the search such as “hypnosis for pain control in labour”. Hypnosis can be used in a wide variety of conditions. It is frequently used in pain control which includes pain in labour, palliative (terminal) care or painful procedures such as dental surgery. The mind is very important in the interpretation of pain and the presence of fear and anxiety adds greatly to the distress. Hypnosis appears to be very effective in children. As there is a considerable amount of evidence, I shall be quite frugal with the references, tending to concentrate on systematic reviews where possible. The Cochrane reviews are very strict in terms of the quality of research that they will accept but the general theme with hypnosis seems to be that there are comparatively few papers of adequate quality.

To turn to other sources of reviews:

Adverse Effects of Hypnosis

Reports of hypnosis give remarkably few adverse effects and so it appears to be comparatively safe. However, anything that controls the mind must be treated with respect and if therapy is required it is important to consult a practitioner who has been adequately trained. Outside environments such as the NHS, there is very little regulation. Stage hypnosis as a form of entertainment is to be depreciated.

The serious problem of implantation of false memories is considered below.

Hypnosis for Forensic Purposes

Hypnosis has also been used in forensic investigations. It is claimed that it may be valuable in helping to recall memories more accurately.17Solving crimes with hypnosis Witnesses are extremely poor at recalling an event. Where there are several witnesses, it often seems incredible that they are reporting the same event. However, there are problems with the use of hypnosis and a technique called “cognitive interviewing” is often used instead.18Enhancing witness memory with techniques derived from hypnotic investigative interviewing. A particularly contentious area is “recovered memories” where it is claimed that the intervention has led to suppressed memories being recovered.19Recovered memories These might include such events as abuse in childhood but this is a contentious area with allegations of implantation of false memories.

Recall can often be very poor. Implantation of false memories in vulnerable children or others must be avoided.

Hypnosis and related interventions may be of value in obtaining some recall, whether it is an accurate report of a recently witnessed event or recalling something that was witnessed many years ago, perhaps in childhood. Anyone who is involved in such interventions must be skilled and objective.20Children’s autobiographical reports about sexual abuse There have also been allegations that the intervention may have implanted a false memory. Recall may be inaccurate for other reasons. This is a difficult area that must be managed with extreme care and some scepticism. An innocent person could be imprisoned and put on the sex offenders’ register with devastating consequences if false memories are implanted. Any such intervention, if it is allowed, should be video recorded, with the person’s permission, so that a third party expert can review if it was done properly, without suggestion.

Further Resources

The organisations listed below all claim to be a register of competent and ethical practitioners but remember that there is no statutory regulation of hypnotherapy. Nevertheless, their aims are to be applauded. Doctors, dentists and other health professionals have statutory regulation and there is quality control in the NHS. There seem to be so many registers that it suggests fragmentation and an unsatisfactory lack of confidence by the professionals to allow so many to exist. Every one claims to be the leading organisation.

  • British Hypnotherapy Association
    http://www.hypnotherapy-association.org/
    Founded in 1958. It claims “The organisation of practitioners who have had at least four years of relevant training and who comply with the best professional standards of competence and ethics in hypnotherapy”.
  • British Society of Clinical Hypnosis
    https://www.bsch.org.uk/
    It says, “The British Society of Clinical Hypnosis (BSCH) is a national professional body whose aim is to promote and assure high standards in the practice of hypnotherapy. Registration demands good quality training, ethical practice and adherence to our code of conduct. You can choose a therapist with confidence.”
  • General Hypnotherapy Standards Council and General Hypnotherapy Register
    https://www.general-hypnotherapy-register.com/
    The headline is, “Protecting the Public and Promoting Good Practice, Unity and Continuing Development within the Profession”. It says, “The General Hypnotherapy Standards Council (GHSC) and General Hypnotherapy Register (GHR) are the UK’s largest and most prominent organisations within the field of Hypnotherapy and together present an exemplary model for the simultaneous protection of the public and the provision of practitioner credibility and services.”
  • National Council for Hypnotherapy
    https://www.hypnotherapists.org.uk/
    They say, “The NCH is the UK’s leading not-for-profit hypnotherapy professional association, representing over 1800 professional hypnotherapists. All our practising members are fully insured and trained to the highest standards, so you can choose a hypnotherapist with confidence.”
  • British Society of Clinical and Academic Hypnosis
    www.bscah.co.uk
    This is slightly different in that it was formed in 2007 by the merger of the two professional societies of the British Society of Medical & Dental Hypnosis (BSMDH) and the British Society of Experimental and Clinical Hypnosis (BSECH). It aims to promote the safe and responsible use of hypnosis in medicine, dentistry and psychology. The members are all doctors, dentists, psychologists and other health professionals who use hypnosis as an adjunct in their work.
