EMDR

What happens

You hold a piece of a traumatic memory in mind — the worst image, the belief that came with it, where you feel it in your body — while doing something that occupies your attention at the same time, usually following a moving finger with your eyes, or alternating taps or tones.

Then you notice what shifted, and we go again. Over a session the memory typically loses its charge. It stays a memory. It stops being an event that is still happening.

Why it works — honestly

The evidence that it works for post-traumatic stress is solid; EMDR is recommended in international treatment guidelines. The explanation for why is less settled. The most common account is that holding the memory while your attention is divided taxes working memory, so the memory can be revisited without the full force of it — and gets re-stored differently.

We would rather tell you that the mechanism is debated than pretend otherwise. What matters clinically is that it reliably helps a particular kind of problem.

What it is good for

• Single, bounded traumatic events. An accident, an assault, a death you witnessed, a traumatic birth. This is where EMDR is at its strongest and often its fastest.
• Specific stuck memories inside a longer history, once enough stability is there.

What it is not for

EMDR is not a general-purpose therapy. Used early with complex PTSD, and without the preparation, it can open more than a person can hold — dissociation, flooding, and days of feeling worse. That is not a reason to avoid it. It is a reason to sequence it properly.

In practice we most often use ISTDP to build the capacity to feel, and EMDR on the specific memories that stay stuck. Which comes first depends on you.
