Does EMDR really work? A plain-English guide to trauma therapy

What is EMDR?

EMDR stands for Eye Movement Desensitisation and Reprocessing. It's a structured form of psychotherapy developed in the late 1980s to help people recover from traumatic and distressing experiences. It's best known as a treatment for post-traumatic stress disorder (PTSD), but it's used for a much wider range of concerns too.

How does it work?

When something overwhelming happens, the memory can become 'stuck', stored with all the original images, emotions and body sensations attached. EMDR helps the brain reprocess these memories so they can be filed away properly.

During a session, your psychologist guides you to briefly bring a distressing memory to mind while you follow a back-and-forth movement with your eyes (or another form of left-right, or 'bilateral', stimulation such as gentle taps or tones). This seems to help the brain do what it naturally does during deep sleep: process and integrate experiences. With repeated processing, the memory gradually loses its emotional charge until it feels neutral and manageable.

Does it actually work?

Yes. EMDR is recognised as an effective, evidence-based treatment for PTSD by major bodies including the World Health Organization and the American Psychiatric Association. A large body of research supports its use, and a growing number of studies suggest it can also help with anxiety, depression, grief, phobias and chronic pain. Interestingly, researchers still can't fully explain the exact mechanism, but the evidence that it helps people is strong and well established.

What a course of EMDR involves

EMDR follows eight phases, including:

1. History-taking and understanding your goals
2. Preparation: learning skills to stay grounded and safe
3. Identifying the memories and beliefs to target
4. Reprocessing those memories with bilateral stimulation
5. Strengthening more helpful, balanced beliefs

You stay in control the whole way through, and a good therapist won't rush you; you build safety and stability first.

Is EMDR right for you?

EMDR can be a powerful option if you're carrying memories that still feel raw, intrusive or overwhelming. It's especially well-suited to single-incident trauma and to the cumulative trauma that first responders and others in high-exposure roles often carry.

If you're wondering whether EMDR might help with what you're going through, a psychologist trained in EMDR can talk you through it.
