The term "hypnosis" comes from the ancient Greek word ὕπνος hypnos, "sleep", and the suffix -ωσις -osis, or from ὑπνόω hypnoō, "put to sleep" (stem of aorist hypnōs-) and the suffix -is.[9][10] The words "hypnosis" and "hypnotism" both derive from the term "neuro-hypnotism" (nervous sleep), all of which were coined by Étienne Félix d'Henin de Cuvillers in 1820. These words were popularized in English by the Scottish surgeon James Braid (to whom they are sometimes wrongly attributed) around 1841. Braid based his practice on that developed by Franz Mesmer and his followers (which was called "Mesmerism" or "animal magnetism"), but differed in his theory as to how the procedure worked.

More than 200 years later, research in neuroscience is confirming at least parts of Mesmer’s outlandish theory. No, there is not magnetic fluid coursing through our bodies. But the power of mere suggestion — of imagination, as Franklin phrased it — is a more effective treatment than many modern skeptics might expect, causing real, measurable changes in the body and brain. Hypnotism has been shown to be an effective treatment for psychological problems, like phobias and eating disorders, but the practice also helps people with physical problems, including pain — both acute and chronic — and some gastrointestinal diseases. Physicians and psychologists have observed this with their own eyes for decades; now, many of them say that brain-imaging studies (not to mention the deep respect people tend to have for all things prefixed by “neuro”) are helping them finally prove their point.
Hypnotherapy, while thought of by some as something non-scientific, is a regulated, legitimate form of therapy that can both explore and use a person’s subconscious to better help them through psychotherapy, and also act as a method of therapy that helps relieve a person of symptoms and problems they are afflicted with. Hypnotherapy has proven to be extremely effective in cases with patients suffering from pain and addiction.

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.”

Meditation practice focuses on stilling or emptying the mind. Typically, meditators concentrate on their breath or a sound (mantra) they repeat to themselves. They may, alternatively, attempt to reach a state of “detached observation,” in which they are aware of their environment but do not become involved in thinking about it. In meditation, the body remains alert and in an upright position. In addition to formal sitting meditation, patients can be taught mindfulness meditation, which involves bringing a sense of awareness and focus to their involvement in everyday activities.

"I believe that you are endowed with the power and energy to overcome any obstacle in life but sometimes, when overwhelmed with life's challenges, you lose contact with your own power. I can help you regain balance in life and regain forward momentum to living the life you are destined to live. I am particularly interested in working with individuals and couples struggling with life transitions, those who are walking through loss, and those struggling with addictions and/or substance abuse."

Hypnosis has been used as a supplemental approach to cognitive behavioral therapy since as early as 1949. Hypnosis was defined in relation to classical conditioning; where the words of the therapist were the stimuli and the hypnosis would be the conditioned response. Some traditional cognitive behavioral therapy methods were based in classical conditioning. It would include inducing a relaxed state and introducing a feared stimuli. One way of inducing the relaxed state was through hypnosis.[77]
A person with depression experiences a wide variety of emotions. According to the University of New Hampshire, hypnotherapy can help a person learn to reduce and/or better control feelings of anxiety, stress, and sadness. Hypnotherapy is also used to treat negative behaviors that could be worsening a person’s depression. These behaviors may include smoking and poor eating and sleeping habits.

Pierre Janet originally developed the idea of dissociation of consciousness from his work with hysterical patients. He believed that hypnosis was an example of dissociation, whereby areas of an individual's behavioural control separate from ordinary awareness. Hypnosis would remove some control from the conscious mind, and the individual would respond with autonomic, reflexive behaviour. Weitzenhoffer describes hypnosis via this theory as "dissociation of awareness from the majority of sensory and even strictly neural events taking place."[38]
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).[182]
Hypnotism was one of the earliest psychoanalytic techniques employed by Sigmund Freud, who was introduced to the technique by physician Josef Breuer. Freud and Breuer believed that traumatic memories that were not accessible to the waking mind could be revealed while a person was under hypnosis, thus facilitating a “cure.” Freud eventually abandoned hypnosis in favor of forced association, and then free association, after he found that not all of his patients responded to hypnotism.
The practice of many relaxation techniques is poorly regulated, and standards of practice and training are variable. This situation is unsatisfactory, but given that many relaxation techniques are relatively benign, the problem with this variation in standards is more in ensuring effective treatment and good professional conduct than in avoiding adverse effects. By selecting a license mental health professional (psychologist or social worker), patients are more likely to receive treatment from individuals who are well trained in the appropriate use of behavioral techniques.

Tai chi is a gentle system of exercises originating from China. The best known example is the “solo form,” a series of slow and graceful movements that follow a set pattern. It is said to improve strength, balance, and mental calmness. Qigong (pronounced “chi kung”) is another traditional Chinese system of therapeutic exercises. Practitioners teach meditation, physical movements, and breathing exercises to improve the flow of Qi, the Chinese term for body energy.

"I provide practical ways to approach some of life's most difficult challenges. I offer respect, non-judgement and empathy so that the therapeutic relationship gives you the opportunity for awareness that allows you to grow and find new ways of thinking, feeling and behaving. My clinical experience has been in counseling Adults, Children and Adolescents."

Hypnosis is not a unitary state and therefore should show different patterns of EEG activity depending upon the task being experienced. In our evaluation of the literature, enhanced theta is observed during hypnosis when there is task performance or concentrative hypnosis, but not when the highly hypnotizable individuals are passively relaxed, somewhat sleepy and/or more diffuse in their attention.[174]
Hypnotherapy expert, Dr Peter Marshall, former Principal of the London School of Hypnotherapy and Psychotherapy Ltd. and author of A Handbook of Hypnotherapy, devised the Trance Theory of Mental Illness, which provides that people suffering from depression, or certain other kinds of neurosis, are already living in a trance and so the hypnotherapist does not need to induce them, but rather to make them understand this and help lead them out of it.[24]
