Eye Movement Desensitization and Reprocessing (EMDR)
Learn what EMDR therapy is, how bilateral stimulation helps reprocess traumatic memories, what the 8 phases look like, who it helps, and how to get started.
What is EMDR Therapy?
EMDR, or Eye Movement Desensitization and Reprocessing, is an evidence-based psychotherapy developed by psychologist Dr Francine Shapiro in 1987. Unlike traditional talk therapy, EMDR does not require you to repeatedly retell your story or analyse every detail of your past. Instead, it helps the brain process distressing memories that have become “stuck,” reducing their emotional impact and allowing them to be stored as experiences from the past rather than ongoing threats.
A key part of EMDR is bilateral stimulation, such as guided eye movements, alternating taps, or sounds. While briefly focusing on a distressing memory, this process helps the brain reprocess the experience in a way that feels less overwhelming and more manageable.
EMDR is recognized as a first-line treatment for trauma by leading organizations, including the American Psychological Association, the World Health Organization, and the U.S. Department of Veterans Affairs.
It’s also important to know that EMDR is not only for severe trauma. It can help with experiences such as chronic criticism, emotional neglect, rejection, relationship wounds, or other events that continue to affect how you think, feel, and respond today. If something from your past is still impacting your present, EMDR may be worth exploring.
The Science Behind EMDR
When something overwhelming happens, the brain does not always store it like a normal memory. Under extreme stress, memories can become stuck in a raw, emotionally charged form rather than being fully processed and placed in the past. As a result, reminders such as a smell, tone of voice, or facial expression can trigger the same fear response years later, making the experience feel as if it is happening in the present.
EMDR is based on the Adaptive Information Processing (AIP) model, developed by Dr. Francine Shapiro. This model proposes that the brain has a natural ability to process and integrate difficult experiences, but trauma can overwhelm that system. EMDR helps restart the process, allowing distressing memories to be reorganized and stored more healthily.
One leading explanation for how EMDR works is the working memory hypothesis. Focusing on a distressing memory while simultaneously engaging in bilateral stimulation divides the brain’s attention. Because working memory has limited capacity, memories become less vivid and emotionally intense over time, reducing their impact.
Brain imaging studies support this process, showing decreased activity in fear-related areas and increased activity in regions involved in reasoning and emotion regulation after EMDR treatment.
Who Can Benefit From EMDR?
EMDR is best known for treating PTSD and trauma, including experiences related to abuse, assault, accidents, medical emergencies, combat, and other distressing events. It can help reduce symptoms such as flashbacks, nightmares, hypervigilance, emotional numbness, and persistent feelings of fear or overwhelm.
It is also widely used for anxiety, panic attacks, social anxiety, and phobias. Rather than focusing only on symptom management, EMDR helps address the underlying experiences that may be contributing to ongoing distress.
Many people seek EMDR for childhood experiences that continue to affect their confidence, relationships, or sense of self. Emotional neglect, chronic criticism, bullying, rejection, and inconsistent caregiving can leave lasting impacts long into adulthood. EMDR helps process these experiences and the negative beliefs that often develop from them.
EMDR may also be helpful for grief, depression with a trauma component, low self-esteem, performance anxiety, attachment difficulties, and other challenges rooted in unresolved past experiences.
If a past event continues to influence how you feel, react, or see yourself today, EMDR may be worth exploring. During an initial assessment, your therapist will help determine whether EMDR is an appropriate fit and the best place to begin.
How EMDR Therapy Works
EMDR follows a structured 8-phase approach designed to help clients process difficult experiences safely and effectively. While the process is structured, treatment is tailored to each individual, and your therapist will move at a pace that feels appropriate for you.
The process begins with an assessment of your history, current concerns, and treatment goals. Before any trauma processing takes place, your therapist will help you build grounding and coping skills to ensure you feel prepared and supported throughout the work.
Once you’re ready, you and your therapist will identify specific memories, experiences, or beliefs to target. Using bilateral stimulation, such as guided eye movements, taps, or sounds, you’ll briefly focus on these experiences while your brain processes them in a new way. Over time, distressing memories typically become less emotionally intense and feel more like events from the past rather than ongoing sources of distress.
Throughout treatment, your therapist will regularly check in on your progress, strengthen healthier beliefs, and ensure each session ends with a sense of stability and grounding. The goal is not to erase memories, but to reduce their emotional impact so they no longer interfere with your daily life.
EMDR Vs. Traditional Talk Therapy: Key Differences
Many people who explore EMDR say some version of the same thing: “I understand what happened, but I still feel affected by it.” EMDR is designed to help close that gap between intellectual understanding and emotional experience.
Traditional talk therapies often focus on identifying patterns, challenging beliefs, and developing new ways of thinking. EMDR takes a different approach by helping the brain reprocess the underlying memories that continue to drive distress. As those memories lose their emotional intensity, the negative beliefs attached to them often begin to shift as well.
Unlike many forms of therapy, EMDR does not require you to repeatedly retell your story in detail. During processing, you focus on the memory while engaging in bilateral stimulation, allowing the work to happen without extensive verbal discussion.
EMDR can also be integrated with other therapeutic approaches, including Cognitive behavioural therapy, somatic therapies, and attachment-based work. Rather than replacing other forms of therapy, it often complements them by helping address unresolved experiences at their source.
How Many EMDR Sessions Will I Need?
The length of EMDR therapy depends on your unique experiences and goals.
For a single, well-defined traumatic event, many people experience meaningful improvement within 6 to 12 sessions. More complex concerns, such as childhood trauma, prolonged neglect, multiple traumatic experiences, or C-PTSD, typically require a longer course of treatment.
The goal is not to move as quickly as possible, but to move at a pace that feels safe and sustainable. Your therapist will tailor the process to your needs, ensuring you have the support and resources necessary before deeper processing begins.
Unlike some therapeutic approaches, EMDR generally does not involve extensive homework. Most of the work happens during sessions, although you may be encouraged to note any thoughts, emotions, dreams, or insights that arise between appointments.

Frequently Asked Questions
Yes. EMDR is recognized as an evidence-based treatment by the American Psychological Association, the World Health Organization, and the U.S. Department of Veterans Affairs. It is supported by extensive research, particularly for PTSD, with growing evidence for anxiety, depression, and phobias.
No. You do not need to verbally retell your story. During processing, you hold the memory in mind privately while engaging in bilateral stimulation, which allows the brain to process it without detailed narration.
CBT focuses on changing thought patterns and often includes homework. EMDR targets how memories are stored in the brain and works directly with those memories. It does not require homework and is often used when talk therapy alone has not been fully effective.
Progress is measured by a reduced urge to perform compulsions and less anxiety when facing triggers. As treatment progresses, most people find that their intrusive thoughts lose their power and disruptions to daily life decrease significantly. Therapists monitor symptoms and adjust exposure plans to ensure continued progress.
ERP therapy is not physically painful or traumatic, but it can cause emotional discomfort in the short term because clients face their fears and anxieties head-on. Sessions are carefully structured by trained therapists to ensure exposures feel challenging yet safe, with distress decreasing over time as new coping skills and confidence develop. Most people find the process manageable and ultimately empowering.
Temporary increases in emotion can happen as processing continues. Your therapist will help you manage this with grounding tools and adjust pacing as needed to keep you supported.
No. EMDR can help with any distressing memories that affect your current life, including anxiety, grief, depression, phobias, and low self-esteem.
Sessions usually last 50 to 90 minutes. Longer sessions are often used during active processing to allow enough time to work through material and close safely.
Yes. EMDR can be used alongside psychiatric medication. Many people use both together as part of a broader treatment plan.
