How Eye Movement Desensitization and Reprocessing Works by Jeff Dwarshuis LMSW ACSW
Eye Movement Desensitization and Reprocessing (EMDR) was developed by Francine Shapiro in 1989 and it successfully treats Posttraumatic Stress Disorder (PTSD). But how?
Brain scans studies of traumatized individuals found that traumatic experience negatively impacts brain functioning.
During trauma a part of the brain called the amygdala, which controls responses associated with fear, becomes over activated and this creates an impasse between itself and the hippocampus.
The hippocampus plays an important role in the consolidation of information from short term memory to long term memory and spatial orientation.
The impasse between the hippocampus and the amygdala creates symptoms found in generalized anxiety, panic attacks and posttraumatic stress disorder.
Brain scans of individuals doing EMDR indicate that this impasse is corrected as eye movements activate the hippocampus so it can receive the overwhelming amount of information from the amygdala and then sort it.
The hippocampus then completes the proper brain processing by sending information to the anterior cingulate cortex, which is involved in aspects such as attention, decision making, reward anticipation, ethics, morality, impulse control, and emotion.
The impact of opening this impasse and restoring proper brain functioning means that a negative memory, once too overwhelming to manage, is put into the proper context of time and space, has affective and cognitive aspects of the memory merged, is viewed with more rational thought, reason and control, and exists in a clear distinction between the past and the present.
Over 10,000 hours of clinical experience using EMDR
