Key Takeaways
- EMDR is an evidence-based psychotherapy developed by Dr. Francine Shapiro in the late 1980s. It uses bilateral stimulation, such as eye movements, tapping, or tones, to help the brain reprocess traumatic memories
- EMDR is recommended by the APA, WHO, and U.S. Department of Veterans Affairs for PTSD treatment
- A licensed EMDR therapist can help you work through trauma in a structured, safe environment
Trauma does not often stay in the past. For many people, a distressing event, such as an accident, assault, loss, or prolonged stress, continues to surface in daily life through flashbacks, anxiety, and emotional triggers that feel impossible to control.
EMDR therapy, or Eye Movement Desensitization and Reprocessing, is an evidence-based psychotherapy approach designed to help the brain process and re-file those unresolved memories, so they lose their emotional charge. Developed by Dr. Francine Shapiro in the early 1990s, EMDR has since become one of the most researched and widely recommended treatments for trauma-related conditions worldwide.
Unlike traditional talk therapy, it does not require you to describe your experience in detail or confront it through prolonged exposure. Instead, it works by engaging the brain's natural processing mechanisms, and the results are well-documented.
What is EMDR Therapy?
EMDR therapy is a structured, evidence-based psychotherapy designed to help people process distressing memories that continue to affect their present mental and emotional health.
The core premise is grounded in the Adaptive Information Processing (AIP) model: the idea that traumatic or overwhelming experiences can get "stuck" in the brain's memory network, stored with the original emotions, physical sensations, and beliefs attached to the event. Rather than being filed away like ordinary memories, they remain raw and reactive, triggering distress whenever something in the present environment resembles the original experience.
The American Psychiatric Association recognizes EMDR as an effective treatment for PTSD, particularly for individuals who find it difficult to talk about or relive their trauma verbally. People exploring trauma treatment options often compare these approaches alongside somatic therapy vs EMDR and ART vs EMDR when deciding which modality may fit their needs best.
How Does EMDR Therapy Work?
How EMDR works is a bit of a puzzle at this point. Even those who agree on its efficacy are somewhat conflicted about how and why this treatment option is so effective. To date, there are only theories about how it offers the help it does. Some have attributed the success to principles similar to prolonged exposure therapy.
EMDR therapy requires a series of visits that systematically cover eight phases of treatment. Typically, it takes about 12 sessions to see the full effects of EMDR. Under a therapist’s guidance, you’ll learn to re-process a stressful past experience. Eventually, you’ll begin to bypass the anxiety and fear you once associated with the memory. Essentially, just like with physical wounds, you’ll build a protective barrier over your emotional pain.
EMDR uses dual attention stimulation, or bilateral stimulation, to help you begin to access and relive painful memories without being consumed by them. An EMDR therapist can guide you in remembering the traumatic event and then divert your attention, so you don’t begin to have your typical emotional response. Eye movements and alternating tapping can help you work through your distressing memories.
“When I work with clients experiencing PTSD, I like to learn the clients’ history to then provide them with activities that prepare them to deal with difficult emotions that may come up during the desensitization process.”
- Talkspace therapist Cynthia Catchings, LCSW-S, LCSW-C, EMDR, CFTP
8 Phases of EMDR Therapy
EMDR therapy follows a structured, phased approach developed to ensure both safety and effectiveness. Rather than jumping directly into trauma processing, the protocol builds progressively, starting with history-taking and stabilization before moving into active reprocessing and, finally, consolidation.
The eight phases below represent the complete EMDR treatment arc, and most individuals move through all of them across multiple sessions.
Phase 1: History Taking and Treatment Planning
During the first phase of EMDR, you'll review your history with a therapist to figure out exactly where you are in your treatment and healing process. You'll be asked to discuss the traumatic event so your therapist can identify all potential past traumas that are haunting you. Your therapist will also assess your current level of emotional stability and identify which specific memories to target first, usually beginning with earlier experiences that underlie more recent distress.
Phase 2: Preparation
Together, you'll explore multiple ways that you can begin trying to cope with the stress you feel as a result of the trauma. For example, a therapist can show you how to learn and practice mindfulness, meditation, and deep breathing. This phase also involves explaining the bilateral stimulation process and ensuring you feel safe and informed before any trauma reprocessing begins.
“When I work with clients experiencing trauma, as part of EMDR, I like to do resourcing exercises because it helps the client to relax and discuss their targets with less intensity.”
Talkspace therapist Catherine Richardson, MA, LPC, EMDR Trained Therapist
Phase 3: Assessment
In this phase, your therapist will guide you in identifying the most distressing image connected to the target memory, the negative belief you hold about yourself because of it (for example, "I am powerless"), and the positive belief you would rather hold ("I am in control now"). They will also use standardized measures, such as the Subjective Units of Disturbance (SUD) scale and the Validity of Cognition (VOC) scale, to baseline your distress levels before processing begins.
Phase 4: Desensitization
During the desensitization phase, you’ll attempt to rationally evaluate your trauma. The goal of this phase is to reprogram how your brain associates the actual trauma with the triggers you’re struggling with.
To help you achieve this, you’ll focus on the memory or image that you normally have a reaction to, while at the same time making eye movements using bilateral stimulation. Bilateral stimulation happens in 25-second-sets that repeat.
After each set, your therapist will ask you to take a deep breath, and then you’ll give feedback about the experience. Note the type of trauma you experienced, and your reaction to the stimulation may result in your therapist adjusting minor parts of the process. This can include how fast the stimulation goes, the type of stimulation that’s being used, and how long the sets are.
Phase 5: Installation
Phase 5 involves your therapist helping you replace the negative belief associated with the trauma with a deeply held positive one. Installation continues using bilateral stimulation until the positive belief reaches a VOC score of 6 or 7 out of 7, indicating it feels fully true.
Phase 6: Body Scan
The body scan phase involves bringing back and reevaluating the traumatic event. During this phase, somatic responses like raised blood pressure, muscle tension, or an increased pulse will help your therapist understand if you’re still experiencing residual trauma. If that’s the case, he or she will continue additional sessions of bilateral eye movement until you can complete the body scan without any responses.
Phase 7: Closure
During the closure phase, stress reduction techniques will be strongly emphasized. Your therapist will likely ask you to keep a record of any incidents you have before your next session. And, you’ll get detailed instructions on how to manage and handle additional occurrences should they occur.
Phase 8: Reevaluation
In this phase, you and your therapist will assess how effective the treatment has been and discuss whether or not future sessions are a good idea. You may also plan at least one final additional follow-up session, if needed.
Together, the eight phases ensure EMDR is not simply symptom management; it is a complete reprocessing of the memories driving those symptoms.
Which Conditions Does EMDR Therapy Treat?
EMDR therapy was originally developed for PTSD, but its clinical applications have expanded significantly as the evidence base has grown. It is now used to treat a range of trauma-linked and trauma-adjacent conditions. If you are living with any of the following, EMDR may be worth discussing with a mental health professional:
- PTSD: The primary and most extensively researched application, supported by the APA, WHO, and VA/DoD
- Anxiety disorders: Including generalized anxiety, panic disorder, and social anxiety, particularly where distressing memories are a contributing factor
- Depression: Especially where depressive episodes are tied to unresolved adverse life experiences
- Specific phobias: Including phobias rooted in past traumatic events or conditioning experiences
- Chronic pain: Emerging research supports EMDR's role in reducing pain intensity when psychological trauma is a contributing component
EMDR is also being explored for grief, substance use disorders, and performance anxiety, with promising early results. If you are unsure whether your experience qualifies, a licensed therapist can help you determine whether EMDR is an appropriate fit.
“When I work with clients that have experienced severe trauma, EMDR is one of my preferred types of therapy since I can start seeing results within the first session; it typically allows clients to process and heal faster than other therapeutic modalities.”
- Talkspace therapist Cynthia Catchings, LCSW-S, LCSW-C, EMDR, CFTP
How Effective is EMDR Therapy?
EMDR's effectiveness for PTSD is among the most well-documented in trauma psychology. Across decades of research and independent clinical reviews, it has consistently demonstrated meaningful reductions in PTSD symptoms, with results that hold over time.
Major health bodies have given EMDR their highest recommendation for PTSD treatment. The VA/DoD Clinical Practice Guidelines place EMDR at the same level as Cognitive Processing Therapy and Prolonged Exposure. The World Health Organization recommends EMDR and trauma-focused CBT as the only two psychotherapies for PTSD in children, adolescents, and adults. The American Psychiatric Association has given EMDR the same status as CBT for reducing symptoms of both acute and chronic PTSD.
The research base is substantial and growing. A meta-analysis of 26 randomized controlled trials published in Frontiers in Psychology found EMDR significantly reduced PTSD, depression, anxiety, and subjective distress symptoms. A 2024 meta-analysis published in the Journal of Clinical Medicine, analyzing 25 RCTs with over 1,000 participants, found EMDR produced significant reductions in depression symptoms, with greater effects in more severe cases.
A 2025 systematic review published in the British Journal of Psychology found EMDR comparably effective to trauma-focused CBT in reducing PTSD symptoms in adults and identified it as the most cost-effective intervention among 11 treatment options compared.
For veterans specifically, a 2025 multisite chart review by Fairbanks et al. examined 279 veterans receiving EMDR either in person or via telehealth. Both groups showed significant improvements in PTSD and depression symptoms, with largely similar outcomes across delivery formats; an important finding for veterans accessing care remotely.
Unlike trauma-focused CBT, EMDR doesn't require detailed verbal recounting of the traumatic event, direct challenging of beliefs, extended exposure exercises, or homework between sessions. For people who struggle to verbalize their trauma, this distinction can make the difference between engaging with treatment and avoiding it altogether.
The evidence is clear: EMDR is an effective, well-validated, and increasingly accessible treatment for PTSD and related conditions.
What to Know Before Starting EMDR
You might be nervous before starting EMDR therapy, and that's okay. Starting work with a new counselor or therapist, especially one using such a unique method, can be a little unnerving. But there's no need to be anxious about what will happen during your appointment.
EMDR might trigger strong emotions
Remembering and reliving traumatic situations can invoke a lot of powerful emotions, from fear and stress to panic. All of this is normal, and your therapist won't be surprised if you are emotional during your sessions. In fact, they'll expect you to have some sort of reaction. Accept your feelings as they come, and don't pass judgment on your experience. Healing takes time. It's also normal for new memories or associated experiences to surface between sessions; your therapist will give you containment tools to manage this.
Dual attention stimulation can feel strange at first
Whether your therapist uses lights, hand-held buzzers, auditory tones, or some other method to induce bilateral stimulation, there's no denying it can feel a little odd. You may be wondering how casting your eyes back and forth can be therapy. But it is.
Taking some time to get accustomed to EMDR is perfectly normal. If you are accessing EMDR via telehealth, bilateral stimulation is typically delivered through on-screen visual cues or audio tones through headphones, equally effective and easy to adapt to from home.
Your thoughts may surprise you
You may go into therapy thinking you'll talk exclusively about one traumatic event. But if you suddenly start to remember everything unusual or uncomfortable that's ever happened to you, don't be alarmed.
If you begin talking about experiences from childhood, or high school, or college, your therapist isn't going to think anything is wrong. Know that your mind might wander, and feel free to follow where it goes. This is actually the AIP model working as intended; the brain is surfacing connected memory networks for processing. Your therapist is trained to navigate this and will keep the session structured and safe.
Is EMDR Therapy Right for You?
EMDR therapy is not a one-size-fits-all solution, but it is appropriate for a wide range of people living with unresolved trauma. It tends to be most effective for those with clearly identified traumatic memories driving current symptoms, whether that's a single incident or a pattern of adverse experiences.
EMDR is generally suitable across age groups, including adolescents; for those working with younger clients, it is important to seek a therapist with specific pediatric EMDR training. If you have complex trauma, a dissociative disorder, or significant mental health comorbidities, your therapist may recommend additional stabilization work before beginning active reprocessing.
Why Choose Online Options for EMDR Therapy?
EMDR therapy is a structured, evidence-based approach that helps people process traumatic memories and reclaim a sense of peace. Finding a therapist trained in EMDR, however, can feel overwhelming. That's where online therapy makes a real difference.
Talkspace can connect you with EMDR-trained therapists who tailor each session to your specific trauma history and healing goals, all from the comfort of your own space. Whether you are working through PTSD, anxiety, or unresolved trauma, consistent professional support is what drives lasting change. Don't put your healing on hold, and connect with a licensed therapist at Talkspace to take your first step.
Frequently Asked Questions (FAQs)
How long does EMDR therapy take?
The length of EMDR therapy varies depending on the complexity and severity of the challenges, but many people notice improvement within 6–12 sessions. More complex trauma or deeply rooted anxiety may require several months of weekly sessions, while some may need occasional follow-ups afterward.
Does EMDR work for anxiety that isn't PTSD?
Yes, EMDR can be effective for anxiety even when it isn’t related to PTSD, as it helps process distressing memories and reduce emotional intensity. Research shows it can also ease phobias, panic, and general anxiety by targeting the underlying emotional triggers.
Is EMDR safe for children?
Yes. EMDR is widely used with children and adolescents, including EMDR for teens, with a strong safety record. Always seek a therapist with specialist pediatric EMDR training and EMDRIA credentials.
What should I expect in my first EMDR session?
In your first EMDR session, the therapist will typically gather your history, discuss your anxiety or distressing experiences, and explain how EMDR works. You may also identify specific memories or triggers to target in future sessions, but the actual eye movement or bilateral stimulation usually begins after this initial assessment.
How do I find a certified EMDR therapist?
You can find a certified EMDR therapist by visiting the official EMDR International Association (EMDRIA) website and using their therapist locator. Additionally, you can ask your primary care doctor or mental health provider for referrals, ensuring the therapist has completed EMDR-specific training and certification.
