EMDR (Eye-Movement Desensitization and Reprocessing) is an incredibly effective treatment created by Dr. Francine Shapiro in the 1990s for Post-Traumatic Stress Disorder and trauma. Since this time, EMDR has been adapted to help with a variety of issues, from depression & anxiety, to relationship issues, to chronic pain. EMDR is an efficient therapy, in that it will often shorten the length of time in treatment for complex issues.
EMDR treatment involves bilateral stimulation, often in the form of rapid eye movements. Bilateral stimulation has been found to effectively treat the way trauma is stored in the brain and helps to adaptively resolve presenting problems that have underlying causes rooted in the past.
Issues like depression, anxiety, & chronic pain can be effectively treated with EMDR, because of the underlying issues that are resulting in the expression of these problems. As an example, an issue like persistent anxiety is often there to distract oneself from underlying feelings related to past trauma.
