EMDR Therapy: What It Is and How It Helps

by | Mar 24, 2026 | Mental Health | 0 comments

Around 70 percent of people worldwide will experience a potentially traumatic event in their lifetime — yet only about 6 percent go on to develop post-traumatic stress disorder (World Health Organization, 2024). For those who do, the effects can be pervasive: intrusive memories, hypervigilance, avoidance of anything remotely connected to the event. Traditional talk therapy helps many individuals work through these symptoms over time. But what about the person who struggles to put their trauma into words at all? This is where EMDR therapy offers something genuinely different. Eye Movement Desensitization and Reprocessing — EMDR — is a structured psychotherapy approach that uses bilateral stimulation (typically guided eye movements) to help the brain reprocess traumatic memories. Developed by psychologist Francine Shapiro in 1989, it has grown from a novel hypothesis into one of the most extensively researched treatments for trauma. The World Health Organization, the American Psychiatric Association, and the U.S. Department of Veterans Affairs all recognize EMDR as an effective intervention for PTSD. And yet, many people have never heard of it. Or they’ve heard the name and dismissed it as something fringe. Quite the opposite.

How EMDR Treatment Actually Works

Most therapeutic approaches involve talking through a difficult experience in detail, session after session. EMDR takes a fundamentally different path. Rather than focusing primarily on the traumatic narrative itself, EMDR targets the way that memory is stored in the brain. The theory behind this — called the Adaptive Information Processing model — suggests that trauma disrupts the brain’s natural ability to integrate experiences. Normally, when something distressing happens, the brain files that event away in a manner that allows us to learn from it without being overwhelmed. Trauma can interrupt this process, leaving memories “stuck” in their raw, unprocessed form. A sound, a smell, even a particular time of year can suddenly bring the full emotional weight of that experience rushing back. So what does an EMDR session actually look like? A trained therapist guides the individual through a set of bilateral or two sides of the brain, stimulations — often side-to-side eye movements, though right and left hand tapping or right and left ear auditory tones are also used — while the person briefly attends to the distressing memory. This dual attention appears to help the brain “unstick” and reprocess the experience more adaptively. The memory itself doesn’t disappear. But its emotional charge diminishes–often significantly. Does that sound too simple? Many clinicians were skeptical early on, too. However, three decades of randomized controlled trials have consistently shown that EMDR produces real, measurable change. The data is hard to argue with.

What the Research Tells Us About EMDR for PTSD

The evidence base for EMDR is substantial and continues to build. A 2025 systematic review and meta-analysis published in JAMA Psychiatry — analyzing 34 randomized clinical trials involving 3,208 participants — found that evidence-based trauma treatments led to PTSD diagnosis loss in 65 to 86 percent of non-military participants. The researchers identified eye movement desensitization and reprocessing as having the highest proportion of diagnosis loss among all psychotherapies examined (Milligan et al., 2025). A separate 2026 meta-analysis in the Journal of Affective Disorders examined 12 RCTs comparing EMDR directly to waitlist controls in adults living with PTSD. EMDR more than doubled the likelihood of losing a PTSD diagnosis (Risk Ratio: 2.13) and produced a large effect in symptom reduction at post-treatment (Villegas-Ortega et al., 2026). Beyond PTSD symptoms alone, participants also experienced improvements in depression, anxiety, and sleep quality. And EMDR’s applications extend well beyond trauma. A 2015 study of 32 individuals receiving inpatient care for depression found that 68 percent of those treated with EMDR achieved full remission — with fewer relapses at the one-year follow-up (Hase et al., 2015). Research on panic disorder has found EMDR to be comparable to CBT in reducing symptoms (Faretta & Dal Farra, 2019). These numbers tell a consistent story; EMDR works, and it frequently works faster than traditional approaches — particularly for individuals who find it difficult to verbalize what they’ve been through.

Beyond PTSD: Co-Occurring Disorders and the Case for EMDR in IOP

One of the most persistent misconceptions about EMDR is that it’s only for PTSD. While EMDR for PTSD remains its strongest evidence base, clinicians now use this modality to address anxiety, depression, substance use disorders, and a range of conditions rooted in adverse life experiences. This matters especially for individuals living with co-occurring disorders — when a mental health condition and a substance use disorder exist at the same time. According to SAMHSA, half of all individuals with substance use disorders also have a co-occurring mental health condition. For many of them, unresolved trauma sits at the center of both struggles. You can address the substance use, but if the underlying trauma remains untouched? The cycle often continues. Which raises a question worth sitting with: how many people in treatment for anxiety, depression, or substance use have never been asked about their trauma history? At Waterview Behavioral Health, we include EMDR as part of our Intensive Outpatient Program — something that remains uncommon in IOP settings across Connecticut and nationally. Many IOPs rely exclusively on traditional group and individual modalities. Our clinical team recognized that for individuals living with PTSD and trauma, offering evidence-based, trauma-specific treatment within the IOP framework leads to more meaningful and durable progress. We utilize the Group Traumatic Episode Protocol (GTEP) group therapy curriculum that grounds, contains and prepares clients for future EMDR work. Our IOP program runs three days per week and integrates group therapy, individual therapy, family therapy, and medication management overseen by our board-certified Medical Director — who holds dual specialization in General Psychiatry and Addiction Psychiatry. When clinically indicated, EMDR is incorporated into individual sessions within that structure, allowing participants to process trauma while simultaneously building coping skills and community in group settings.

What to Consider Before Starting EMDR

EMDR is not for everyone, and a responsible clinician will be straightforward about that. The eight-phase protocol requires a therapeutic relationship built on trust and psychological safety. Individuals in active crisis, those who haven’t yet stabilized from acute withdrawal, or people with certain dissociative conditions may need preliminary stabilization work before beginning EMDR treatment. But for many people — particularly those who have tried talk therapy and felt stuck, or who carry experiences they’ve never been able to fully articulate — EMDR offers a path that simply wasn’t available to them before. The endorsements from the APA, the VA, and the World Health Organization are not arbitrary. And the clinical outcomes we observe at Waterview echo what the research describes: individuals who had been living under the weight of unprocessed trauma finding — sometimes for the first time — that the memory no longer controls them. Recovery is rarely linear. Every person’s experience is different. But the evidence points in a hopeful direction, and hope, in behavioral health, is no small thing.
