If you searched for “MDR therapy,” you’re most likely looking for EMDR therapy, short for Eye Movement Desensitization and Reprocessing. It’s a psychotherapy approach designed to help the brain process traumatic memories that have gotten “stuck,” and it’s one of the most researched treatments for PTSD. Both the World Health Organization and the American Psychological Association recommend it for trauma treatment in children, adolescents, and adults.
There is a separate medical use of the abbreviation MDR, which stands for multidrug-resistant, a term describing bacteria that no longer respond to multiple antibiotics. If that’s what brought you here, “MDR therapy” refers to specialized treatment strategies for these resistant infections, not a single therapy. The rest of this article covers EMDR, since that’s what the vast majority of searchers are looking for.
How EMDR Works
EMDR is built on a framework called the Adaptive Information Processing model. The core idea is straightforward: your brain has a natural ability to process stressful experiences and file them away. But when something is overwhelming enough, that system can stall. The memory gets stored in its raw form, still carrying the original images, emotions, and physical sensations as if the event is still happening. Those unprocessed memories then get triggered by things in your present life, driving anxiety, flashbacks, nightmares, and other symptoms.
During EMDR, a therapist guides you through a series of side-to-side eye movements, tones, or taps while you briefly focus on a disturbing memory. This bilateral stimulation appears to restart the brain’s stalled processing system, allowing the memory to be integrated into your broader memory networks in a way that no longer carries the same emotional charge. You still remember what happened, but the memory loses its ability to hijack your nervous system.
One important distinction from traditional talk therapy: EMDR doesn’t require you to describe the traumatic event in detail, directly challenge your beliefs about it, or do homework between sessions. You hold the memory in mind, but the therapist isn’t asking you to narrate it or relive it at length.
The Eight Phases of Treatment
EMDR follows a structured eight-phase protocol. Not every phase happens in every session, and the pace depends on your needs.
- Phase 1: History and treatment planning. You and your therapist discuss what brought you in, identify the memories that will be targeted, and assess what internal and external resources you already have.
- Phase 2: Preparation. The therapist explains how EMDR works, answers your questions, and teaches you specific coping techniques to handle any emotional disturbance that comes up during or between sessions.
- Phase 3: Assessment. You identify the specific memory to work on, along with the images, negative beliefs, feelings, and body sensations connected to it. The therapist takes baseline measurements of how disturbing the memory feels and how strongly you believe a positive alternative thought.
- Phase 4: Desensitization. This is where the eye movements or taps begin. You focus on the target memory while following the bilateral stimulation, continuing until the distress level drops to zero or near zero. New thoughts, images, and feelings often emerge during this phase.
- Phase 5: Installation. Once the distress is down, you pair a positive belief with the memory and strengthen it until it feels genuinely true.
- Phase 6: Body scan. You hold the memory and the new positive belief in mind while scanning your body from head to toe. Any lingering tension or discomfort is reprocessed.
- Phase 7: Closure. Every reprocessing session ends here. The therapist helps you return to a calm, grounded state, whether or not the memory has been fully processed.
- Phase 8: Reevaluation. Each new session starts by checking in on previously processed memories to confirm the distress is still low and the positive belief still feels solid. From there, you decide what to work on next.
What Sessions Look Like in Practice
A typical EMDR session lasts 60 to 90 minutes. Sessions are usually scheduled once or twice per week, and a full course of treatment generally runs 6 to 12 sessions, though some people need fewer. For a single traumatic event, the reprocessing itself is often completed in about three sessions.
If you’ve experienced multiple traumas or have a complex history, treatment will take longer. The early phases of history-taking and preparation may stretch across several sessions before any reprocessing begins, and each target memory requires its own cycle through the protocol. Speed isn’t the goal. The timeline adjusts to fit your specific situation.
How Effective Is EMDR?
The numbers on EMDR for PTSD are striking. A study at Kaiser Permanente found that 100% of people who experienced a single trauma and 77% of those with multiple traumas no longer met the criteria for PTSD after an average of six 50-minute sessions. Two other randomized controlled trials found that 84% to 90% of single-trauma survivors lost their PTSD diagnosis after just three 90-minute sessions.
In a head-to-head comparison funded by the National Institute of Mental Health, EMDR outperformed a common antidepressant over the same treatment period. At follow-up, 91% of the EMDR group no longer had PTSD, compared with 72% in the medication group. Across the broader research, seven out of ten studies found EMDR to be faster or more effective than trauma-focused cognitive behavioral therapy.
Conditions Beyond PTSD
EMDR was originally developed for trauma, but its use has expanded considerably. A systematic review of 90 studies identified positive effects across 14 different categories of clinical conditions. These include anxiety disorders, mood disorders like depression, chronic pain, obsessive-compulsive disorder, performance anxiety, addiction, sleep problems, eating disorders, personality disorders, and childhood mental health conditions. Pain alone accounted for 22 studies, and anxiety disorders had 11.
The logic behind this expansion ties back to the underlying model. Many conditions that don’t look like PTSD on the surface still have roots in unprocessed distressing experiences. A phobia might trace back to a single frightening event. Chronic pain can be maintained by the nervous system’s response to earlier trauma. EMDR targets those foundational memories regardless of the diagnosis attached to the current symptoms.
Finding a Qualified Therapist
EMDR should be delivered by a licensed mental health professional who has completed an approved basic training program. To become certified through the EMDR International Association, a therapist needs a full independent practice license, completion of an approved training, 20 hours of supervised consultation with an approved consultant, 12 hours of continuing education specific to EMDR, and letters of recommendation from both a consultant and professional peers. All consultation hours must be completed within five years of application.
When searching for a provider, look for someone who is either EMDRIA-certified or has at minimum completed an EMDRIA-approved basic training. Therapists still in training can practice EMDR, but they should be receiving active supervision from a certified consultant. You can search the EMDRIA directory to find practitioners in your area.
