You may have heard of EMDR from a friend, a podcast, or a headline. Or perhaps your GP or a previous therapist mentioned it as something worth exploring. Whatever brought you here, the question is a fair one: what exactly is EMDR therapy, and does it actually work?
The short answer is yes, and the evidence is substantial. But understanding why it works, and whether it might be right for you, takes a little more unpacking. If you’re based in Chelsea in London or Weybridge in Surrey and you’re dealing with trauma, PTSD, or experiences that still feel emotionally raw even years later, this article is written for you.
What Is EMDR Therapy?
EMDR stands for Eye Movement Desensitization and Reprocessing. It’s a structured, evidence-based psychological therapy developed in the late 1980s and now recommended by the World Health Organization, the NHS, and NICE (the National Institute for Health and Care Excellence) for the treatment of post-traumatic stress disorder.
Despite its name, EMDR isn’t just about eye movements. It’s a therapy that works by helping the brain complete an interrupted process, the natural processing of distressing experiences that, for various reasons, never quite finished. When trauma occurs, the memory doesn’t always get stored the way ordinary memories do. Instead, it can become “frozen” in the nervous system, retaining its original emotional intensity and being easily triggered by things in the present.
EMDR uses a technique called “bilateral stimulation,” typically following a therapist’s moving finger with your eyes, though tapping or auditory tones are also used while holding a distressing memory in mind. This appears to activate the brain’s natural information processing system, allowing the memory to be digested and stored in a way that no longer carries the same charge.
Think of it this way: when we sleep and enter REM (rapid eye movement) sleep, our eyes move back and forth while our brains process the events of the day. EMDR seems to replicate something similar to this natural mechanism, but in a guided, therapeutic context.
What Does an EMDR Session Actually Look Like?
For many people, the idea of EMDR sounds a little unusual. It’s quite different from conventional talking therapies, and that can make it feel daunting. Here’s what to expect.
EMDR therapy is structured into eight phases, but you won’t be thrown into the deep end. The early sessions focus entirely on building safety, understanding your history, and helping you develop resources for managing distress. Nothing happens before you’re ready.
When you do begin the actual reprocessing work, you’ll be asked to bring a specific distressing memory to mind along with the negative belief associated with it (for example, “I am worthless” or “I am in danger”) while following the bilateral stimulation. You’ll notice what comes up: images, feelings, body sensations, thoughts. The therapist doesn’t interpret these; they simply hold space while your brain does the work.
Over the course of several sets of bilateral stimulation, most people find that the distress connected to the memory begins to reduce. The memory doesn’t disappear, but it loses its emotional grip. What’s left is the factual record of what happened, processed and filed away, without the overwhelming emotional response.
Does EMDR Therapy Really Work? What the Evidence Says
This is where EMDR really stands out from many other therapies. The evidence base is extensive and continues to grow.
A 2025 systematic review and meta-analysis funded by EMDR UK and published in the British Journal of Psychology, one of the most authoritative reviews since the NICE 2018 guidelines, found that EMDR was significantly more effective than waitlist controls and usual care for treating PTSD in adults. Crucially, it was found to be comparable in effectiveness to trauma-focused cognitive behavioral therapy (TF-CBT), which has long been considered the gold standard.
But perhaps more striking was the cost-effectiveness finding: EMDR was identified as the most cost-effective of ten psychological treatments for adults with PTSD. In a context where NHS waiting lists remain long, and many people are seeking private care, this matters.
Other research has shown that some people with single-incident trauma see significant improvement within just a few sessions. Studies have reported that 84–90% of single-event trauma survivors no longer met the criteria for PTSD after three 90-minute EMDR sessions. While not every case is this straightforward, particularly for complex or developmental trauma, these findings are striking and give cause for genuine optimism.
EMDR is also being used increasingly beyond PTSD, with growing evidence supporting its use for depression, anxiety, phobias, and even addictive behaviors. In London, this has begun to attract wider public attention, with individuals openly sharing how EMDR has helped them manage conditions that felt otherwise immovable.
EMDR for Childhood Trauma Specifically
One area where EMDR is particularly valuable is in working with adults who carry the effects of childhood trauma. This is sometimes called developmental or complex trauma, and it can be harder to treat with standard approaches because the traumatic experiences happened repeatedly, often before the person had the language to make sense of what was occurring.
Childhood trauma doesn’t always show up as a single, clear memory. It may be a pervasive feeling of being unsafe, a set of beliefs about yourself that feel unshakeable, or emotional and relational patterns that keep repeating. EMDR is well-suited to this kind of work because it targets not just specific memories but also the core negative beliefs that those experiences created, beliefs like “I am not lovable,” “I am powerless,” or “The world is not safe.”
Working with these at the level of the nervous system, rather than purely through talking, often allows for a depth of change that clients describe as transformative.
Is EMDR Right for You?
EMDR is particularly well-suited for adults who:
- Are experiencing PTSD symptoms (flashbacks, nightmares, hypervigilance, avoidance)
- Have a history of childhood trauma that continues to affect their daily life and relationships
- Feel stuck in anxiety or depression that doesn’t seem to lift despite other interventions
- Notice emotional triggers that feel disproportionate to the present situation
- Are you ready to do some deeper processing work, with the right support in place
It is not necessarily the right starting point for everyone. Some people need to develop greater emotional stability and safety before beginning trauma reprocessing, and a skilled therapist will assess this carefully with you, ensuring that the work is always done at a pace that feels manageable.
At Aimee Griffin Therapy, EMDR Level 1 training informs the trauma work offered to adult clients, used thoughtfully and only where appropriate within a broader therapeutic relationship built on safety and trust.

FAQ: EMDR Therapy in London
Is EMDR available on the NHS in London?
A: EMDR is recommended by NICE and offered through some NHS services, though waiting times can be significant. Many people in Chelsea and Weybridge choose to access EMDR privately for faster, more flexible support.
How many EMDR sessions will I need?
A: This depends on the nature and complexity of your trauma. Single-incident traumas may resolve in as few as three to six sessions. Developmental or complex trauma typically requires longer-term work. Your therapist will give you an honest, personalized view during your initial consultation.
Q: Is EMDR the same as hypnotherapy?
A: No. EMDR is not hypnotherapy and does not involve any kind of trance or suggestion. You remain fully conscious and in control throughout. The bilateral stimulation simply helps your brain’s natural processing system do its work.
Q: Can EMDR be done online?
A: Yes. Online EMDR has been found to be effective, and the bilateral stimulation can be adapted for remote work. This makes it accessible for clients who are not able to attend in person.
What if I can’t remember my trauma clearly?
A: Detailed recall of specific events is not required for EMDR to be effective. The therapy works with whatever material is present — images, emotions, body sensations, or beliefs — and does not depend on being able to narrate a complete or coherent story.
Do you offer EMDR in Chelsea London and Weybridge Surrey?
