EMDR is a multi-faceted approach, not limited to cognitive, behavioral, or somatic methods, but a synthesis of all three and more. The fact that it simultaneously works on mind, body, and emotions may account for its success in taking mere intellectual understanding of the origins of a problem (e.g. “I know I have guilt over killing in the war”) to a holistic resolution involving a bodily release, where post-traumatic symptoms such as intrusive thoughts, nightmares, and anger outbursts clear up. Since all therapies in some way involve getting to the roots of psychological problems, it is a benefit of EMDR that the trauma that must be re-experienced during treatment is relatively short-lived. Cognitive reprocessing occurs simultaneously with memory recall.
