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.

That's not to say that hypnotherapy is a "quick fix." Unfortunately there is no magic wand, no miracle cure, and if I could just click my fingers and change lives then believe me, I'd be a lot richer! Hypnotherapy is something that we, my client and I, do together — they commit to their intentions and I give them the metaphorical assistance they need.
A wide variety of the complementary therapies claim to improve health by producing relaxation. Some use the relaxed state to promote psychological change. Others incorporate movement, stretches, and breathing exercises. Relaxation and “stress management” are found to a certain extent within standard medical practice. They are included here because they are generally not well taught in conventional medical curricula and because of the overlap with other, more clearly complementary, therapies.​therapies.
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.
