how emdr works
Helping stuck memories finish processing
Most difficult experiences get processed naturally over time. We think about them, talk about them, sleep on them, and eventually they become part of our story rather than something we relive. But when an experience is overwhelming, the brain can store it in a raw, unprocessed form, still holding the images, body sensations and beliefs from the moment it happened. That is why a sound, a smell or a tone of voice can bring the old feelings rushing back as if it were happening now.
EMDR is based on a framework called the Adaptive Information Processing (AIP) model. It holds that the brain has a natural capacity to heal, much like the body does, and that EMDR helps remove what is blocking that process so a stuck memory can be linked with healthier, more adaptive information.
The role of bilateral stimulation
During memory work, your therapist guides you through bilateral stimulation: side-to-side eye movements, alternating taps or alternating tones. You hold the memory in mind for short periods while your attention is also on the stimulation.
Researchers are still studying exactly why this helps. One leading explanation is the working memory theory: holding a memory in mind while doing a second task taxes the brain's limited working memory, which makes the memory less vivid and less emotionally intense, and it may be stored again in that calmer form. Others point to the way EMDR keeps you anchored in the present while you revisit the past.
The eight phases of EMDR
1. History and treatment planning. Your therapist learns about your history and goals and identifies memories to target.
2. Preparation. You learn what to expect and build calming and grounding skills you can use during and between sessions.
3. Assessment. You identify the image, negative belief, emotions and body sensations connected to a memory, plus the positive belief you'd like to hold instead.
4. Desensitization. Sets of bilateral stimulation while you notice whatever comes up, until the memory feels less distressing.
5. Installation. Strengthening the positive belief, such as "I survived" or "I'm safe now."
6. Body scan. Checking for any remaining tension or discomfort connected to the memory.
7. Closure. Making sure you leave every session feeling steady, whether or not a memory is fully processed.
8. Reevaluation. Reviewing progress at the next session and deciding what to work on next.
What you'll notice
Clients often describe memories feeling farther away, less vivid or simply "done." Beliefs shift, too: "It was my fault" can become "I did the best I could." Some people notice changes after a few sessions; others, especially those working through long-term or childhood trauma, benefit from a longer course. It's normal for thoughts, dreams or feelings to surface between sessions as processing continues.
