What Is EMDR Therapy, and How Does It Actually Work?

EMDR — short for Eye Movement Desensitization and Reprocessing — is one of the approaches I use most often, and it's also one of the most misunderstood. Here's a straightforward explanation of what it actually is.

The basic idea

When something distressing happens, the memory can get "stuck" — stored in a way that keeps triggering the same emotional and physical reactions long after the event itself. EMDR is a structured therapy approach designed to help the brain fully process those stuck memories, so they stop having the same charge.

What makes it different from talk therapy

Traditional talk therapy relies primarily on discussing what happened. EMDR incorporates bilateral stimulation — usually guided eye movements, though tapping or alternating sounds can also be used — while you briefly focus on a distressing memory. The mechanism isn't fully understood, but it's thought to mimic some of the memory-processing that happens naturally during REM sleep. It's been studied extensively since the late 1980s and is recognized as an effective, evidence-based treatment for trauma by organizations including the World Health Organization and the American Psychological Association.

What a session actually looks like

We don't start with EMDR on day one. Early sessions focus on building safety, understanding your history, and developing coping tools you can use between sessions. When we do begin EMDR, you're never simply reliving the memory in detail out loud — the process is more about noticing what comes up (images, sensations, beliefs) while I guide the bilateral stimulation, in short, structured sets.

How many sessions it takes

This varies a lot depending on what we're working on. A single, specific incident might process in a handful of sessions; more complex or long-standing relational trauma typically takes longer. I always tailor the pace to what feels manageable for you — there's no fixed script.

Is it only for "big T" trauma?

No. While EMDR is well known for treating PTSD, it's also effective for what's sometimes called "small t" trauma — painful relationship patterns, chronic self-doubt, specific triggers — the kind of experiences that don't always feel dramatic enough to "count," but that still shape how you move through the world.

Does it actually work?

EMDR has one of the stronger evidence bases among trauma-focused therapies, though — like any approach — it isn't a guaranteed fit for everyone, and results depend a lot on the person, the issue, and the therapeutic relationship. I'm always upfront if I think a different approach might serve you better.
