What Is EMDR Therapy and How Does It Work?
EMDR (Eye Movement Desensitization and Reprocessing) is a well-researched, eight-phase psychotherapy that helps the brain heal from trauma the same way the body heals from a physical wound. Developed by Dr. Francine Shapiro in the late 1980s, it is now one of the most widely recommended treatments for PTSD — recognized in treatment guidelines from the World Health Organization (WHO), the VA/DoD, and the American Psychological Association (APA).
When a distressing event happens, the brain’s natural information-processing system can get “stuck.” The memory gets stored with all its original sights, sounds, body sensations, and emotions intact — so years later, a trigger can make you feel like the event is happening all over again.
During an EMDR session, you briefly recall a disturbing memory while simultaneously attending to bilateral stimulation — typically side-to-side eye movements following the therapist’s hand, but sometimes tapping or tones. This dual attention mimics the brain’s REM sleep state and appears to activate the same memory-reconsolidation process that normally happens overnight. The memory begins to “digest”: the emotional charge fades, and the event is filed away as a past memory rather than an ongoing threat.
The Eight Phases of EMDR Therapy
- History & Treatment Planning — what to work on and in what order
- Preparation — grounding tools and safety skills
- Assessment — identifying the target memory, its negative belief, and the desired positive belief
- Desensitization — the core reprocessing phase (eye movements + memory)
- Installation — strengthening the new, positive belief
- Body Scan — checking that the memory no longer lives in the body as tension or distress
- Closure — returning to equilibrium at the end of each session
- Re-evaluation — checking progress at the start of each new session
Who Can Benefit From EMDR Therapy?
EMDR can be useful for those struggling with:
- PTSD and single-incident trauma (accidents, violence, combat, assault)
- Complex trauma and childhood abuse
- Anxiety and panic disorders
- Phobias
- Grief and loss
- Chronic pain linked to emotional experience
- Performance blocks (athletes, artists, public speakers)
Unlike talk therapy, EMDR does not require you to describe your trauma in excruciating detail or do “homework” between sessions. It does not require years of weekly appointments to see change. And because it works at the brain’s level — not just through talking — it can reach memories that words alone cannot touch.
