Hypnotherapy has become a well-established therapeutic method in German-speaking countries over the last few decades. Knowledge of the effects of hypnosis has expanded, experience with its clinical application has become more differentiated, and the evidence for its efficacy is now better grounded. The cerebrophysiological and biochemical effects of hypnosis are being increasingly investigated, and genetic associations are being recognized. This book provides a compact overview, on a solid specialist basis, of the mechanism of effect, practical procedure and areas of application, illustrated with example cases.
