After developing a substantial following — “mesmerism” became “the height of fashion” in late 1780s Paris, writes Marchant — Mesmer became the subject of what was essentially the world’s first clinical trial. King Louis XVI pulled together a team of the world’s top scientists, including Benjamin Franklin, who tested mesmerism and found its capacity to “cure” was, essentially, a placebo effect. “Not a shred of evidence exists for any fluid,” Franklin wrote. “The practice … is the art of increasing the imagination by degrees.”
“Each unhealthy current behavior, such as smoking, losing one’s temper, excessive alcohol consumption, or compulsive overeating has a chain of events that laid the foundation for all of our current unhealthy choices. Through the ‘memory chip’ that has been laid down in the subconscious mind, we can trace back the experiences and subconscious decisions we made as children that may be leading us to the behavior that is no longer healthy for us.”
Neuro-Linguistic Programming (NLP) is the name given to a series of models and techniques used to enhance the therapist's ability to do hypnotherapy. NLP consists of a number of models, with a series of techniques based on those models. Sensory acuity and physiology is one model whose premise is that a person's thought processes change their physiological state. People recognize such a physiological change when startled. The body receives a great dose of adrenaline, the heart beats faster, the scare may be verbalized by shouting, and the startled person may sweat. Sensory acuity, (i.e., being attuned to changes occurring in another person) will strengthen communication to a person in ways over and above simple verbal cues, therefore making the therapist more effective. A second model of NLP deals with representational systems. The idea behind this model is that different people represent knowledge in different sensory styles. In other words, an individual's language reveals that person's mode of representation. There are three basic modes of representation. These are: Auditory, Visual, and Kinesthetic. The same information will be expressed differently by each. For example, the auditory person might say, "That sounds good to me;" the visual person might convey, "I see it the same way;" and the kinesthetic person would offer, "I'm comfortable with it too."
Braid soon assimilated Carpenter's observations into his own theory, realising that the effect of focusing attention was to enhance the ideo-motor reflex response. Braid extended Carpenter's theory to encompass the influence of the mind upon the body more generally, beyond the muscular system, and therefore referred to the "ideo-dynamic" response and coined the term "psycho-physiology" to refer to the study of general mind/body interaction.
But for the comparison between PHA and functional amnesia to be most meaningful, we need to know that they share underlying processes. One way to test this is to identify the brain activity patterns associated with PHA. In a groundbreaking study published in Neuron, neuroscientist Avi Mendelsohn and colleagues at the Weizmann Institute in Israel did just that using functional magnetic resonance imaging (fMRI). They carefully selected 25 people to participate in their experiment. Although all were susceptible to hypnosis, earlier testing had shown that half could respond to a PHA suggestion (labelled “the PHA group”) and half could not (the “non-PHA group”). In the Study session of their experiment, participants watched a 45-minute movie. One week later, in the Test session, participants returned to the laboratory and were hypnotized while they lay within the fMRI scanner. During hypnosis, people in both the PHA and non-PHA groups received a suggestion to forget the movie until they heard a specific cancellation cue.
An approach loosely based on information theory uses a brain-as-computer model. In adaptive systems, feedback increases the signal-to-noise ratio, which may converge towards a steady state. Increasing the signal-to-noise ratio enables messages to be more clearly received. The hypnotist's object is to use techniques to reduce interference and increase the receptability of specific messages (suggestions).
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
Braid worked very closely with his friend and ally the eminent physiologist Professor William Benjamin Carpenter, an early neuro-psychologist who introduced the "ideo-motor reflex" theory of suggestion. Carpenter had observed instances of expectation and imagination apparently influencing involuntary muscle movement. A classic example of the ideo-motor principle in action is the so-called "Chevreul pendulum" (named after Michel Eugène Chevreul). Chevreul claimed that divinatory pendulae were made to swing by unconscious muscle movements brought about by focused concentration alone.
But psychiatrists do understand the general characteristics of hypnosis, and they have some model of how it works. It is a trance state characterized by extreme suggestibility, relaxation and heightened imagination. It's not really like sleep, because the subject is alert the whole time. It is most often compared to daydreaming, or the feeling of "losing yourself" in a book or movie. You are fully conscious, but you tune out most of the stimuli around you. You focus intently on the subject at hand, to the near exclusion of any other thought.

For some psychologists who uphold the altered state theory of hypnosis, pain relief in response to hypnosis is said to be the result of the brain's dual-processing functionality. This effect is obtained either through the process of selective attention or dissociation, in which both theories involve the presence of activity in pain receptive regions of the brain, and a difference in the processing of the stimuli by the hypnotised subject.
Stage hypnosis is a form of entertainment, traditionally employed in a club or theatre before an audience. Due to stage hypnotists' showmanship, many people believe that hypnosis is a form of mind control. Stage hypnotists typically attempt to hypnotise the entire audience and then select individuals who are "under" to come up on stage and perform embarrassing acts, while the audience watches. However, the effects of stage hypnosis are probably due to a combination of psychological factors, participant selection, suggestibility, physical manipulation, stagecraft, and trickery. The desire to be the centre of attention, having an excuse to violate their own fear suppressors, and the pressure to please are thought to convince subjects to "play along". Books by stage hypnotists sometimes explicitly describe the use of deception in their acts; for example, Ormond McGill's New Encyclopedia of Stage Hypnosis describes an entire "fake hypnosis" act that depends upon the use of private whispers throughout.
"How long will I spend in therapy?", is like asking, "How long is a piece of string?" Everyone is different and everyone's individual needs and circumstances vary. There is no definitive answer. However, while some talking therapies can require commitments of a year or more, hypnotherapy tends to be a much faster solution. The average length of time I spend with a client is around 4-6 weekly sessions, to create sustainable changes which some have been trying to implement for years.
It is used for a wide variety of applications, and studies into its efficacy are often of poor quality which makes it difficult to determine efficacy. Several recent meta-analyses and systematic reviews of the literature on various conditions have concluded that the efficacy of hypnotherapy is "not verified", that there is no evidence or insufficient evidence for efficacy.
