EMDR, or eye movement desensitization and reprocessing, is a structured psychotherapy designed to help people process distressing memories, especially those linked to trauma. During EMDR therapy, a trained therapist guides you to briefly focus on a memory while doing bilateral stimulation, such as following side-to-side eye movements. EMDR is recognized by major health organizations as an effective treatment for PTSD.
What is EMDR?
EMDR was developed in the late 1980s by psychologist Francine Shapiro and has since been studied extensively. It is based on the idea that traumatic or very upsetting experiences can be stored in the brain in a "stuck" way, with the original images, emotions, beliefs and body sensations still feeling raw. Reminders can trigger these memories as if they were happening now.
EMDR aims to help the brain reprocess these memories so they become less vivid and distressing and more like ordinary memories of the past. The goal isn't to forget what happened, but to remember it without being overwhelmed.
Unlike some talking therapies, EMDR doesn't require describing traumatic events in detail or doing extensive homework. Many people find this appealing, especially if speaking about the trauma feels too difficult. EMDR is an integrative therapy and is usually delivered by a licensed mental health professional, such as a psychologist or psychotherapist, with specific EMDR training.
How EMDR works: the eight phases
EMDR therapy follows a structured, eight-phase protocol:
- History and treatment planning: the therapist learns about your history, current difficulties and goals, and identifies target memories.
- Preparation: you learn what to expect and practice coping and calming techniques, so you have tools if emotions become intense.
- Assessment: you identify a target memory, including an image, a negative belief about yourself (such as "I'm powerless"), a positive belief you'd prefer, and related emotions and body sensations.
- Desensitization: you hold the memory in mind while following the therapist's hand or a light bar with your eyes, or while experiencing tapping or alternating sounds. After each set, you notice what comes up.
- Installation: strengthening the positive belief.
- Body scan: checking for remaining tension.
- Closure: returning to calm at the end of each session.
- Reevaluation: reviewing progress at the next session.
Exactly how bilateral stimulation contributes is still debated among researchers, but the overall approach has strong evidence for trauma.
EMDR for PTSD and other conditions
EMDR for PTSD is where the evidence is strongest. International clinical guidelines recommend it, alongside trauma-focused cognitive behavioral therapies, as a first-line treatment for post-traumatic stress disorder in adults, and it is also used with children and adolescents.
EMDR may also help with:
- Complex PTSD and the effects of repeated trauma, often as part of a phased approach
- Anxiety and phobias linked to specific frightening experiences
- Distressing memories that aren't formally traumatic but still affect daily life
- Grief, especially after sudden or traumatic loss
- Nightmares related to trauma
Research is growing for conditions such as depression, chronic pain and panic disorder, but the evidence is less established than for PTSD. A therapist can discuss whether EMDR is a good fit for your particular situation, or whether another approach might be better suited.
Does EMDR work?
Many studies have found that EMDR reduces PTSD symptoms, and it is considered an evidence-based treatment by major health organizations. Some people notice improvements after relatively few sessions, especially for single-incident trauma. Complex or multiple traumas usually require more time and preparation.
During and after sessions, it's common to feel tired or emotional, and memories, dreams or feelings may surface. These effects are usually temporary. Your therapist will help you prepare for them and use calming strategies at the end of each session.
EMDR isn't right for everyone at every moment. If you're in an unstable situation, are experiencing severe dissociation, or have certain health conditions, your therapist may recommend stabilization work first or a different approach. That's not a failure; it's careful, safe treatment.
You may come across brainspotting, a related approach that uses fixed eye positions to access distressing material. It is sometimes discussed alongside EMDR, but its research base is much smaller.
What to expect and how to find an EMDR therapist
Look for a licensed mental health professional, such as a clinical psychologist, psychologist or psychotherapist, who has completed recognized EMDR training. It's reasonable to ask about their training, experience with your type of difficulty, and how they adapt EMDR for complex trauma.
Your first sessions will focus on history-taking and preparation rather than processing memories. The therapist will ask about your symptoms, history, current life and support, and teach you techniques to manage distress. Processing begins only when you both feel you're ready.
Sessions typically last around an hour, sometimes longer for processing sessions. EMDR can also be delivered online by therapists trained to do so.
If you are currently in crisis, EMDR isn't the first step. Seek urgent help: call 911 in the US or your local emergency number, call or text 988 (Suicide & Crisis Lifeline, US), or call Samaritans at 116 123 (UK and Ireland).
Frequently asked questions
What is EMDR therapy used for?
EMDR therapy is mainly used to treat PTSD and trauma-related symptoms. It may also help with distressing memories, anxiety and phobias linked to specific events, traumatic grief and trauma-related nightmares. A trained therapist can assess whether EMDR suits your needs or whether another approach would be better.
Does EMDR really work?
Research supports EMDR as an effective treatment for PTSD, and international guidelines recommend it. Many people experience significant reductions in distress linked to traumatic memories. How well it works depends on the person, the type of trauma and the therapist's skill, and it isn't the right fit for everyone.
How many EMDR sessions do I need?
It varies. Some people with a single traumatic event notice meaningful change within a small number of processing sessions, after preparation. People with complex or repeated trauma often need longer treatment. Your therapist will plan and review the number of sessions with you.
Is EMDR the same as brainspotting?
No. Brainspotting is a separate approach that developed from EMDR and uses fixed eye positions to access distressing experiences. EMDR follows a structured eight-phase protocol and has a much larger body of research, especially for PTSD. Ask any therapist about the evidence for the methods they use.
Can EMDR be done online?
Yes. Many therapists trained in EMDR offer it online, using on-screen eye movements, self-tapping or audio for bilateral stimulation. Research and clinical experience suggest it can be effective remotely. It's important to have a private, safe space and a plan with your therapist for managing intense emotions.
