When I tell patients that I work with EMDR, the reactions vary. Some know it already. Others have heard things without much context. And some look skeptical, which is completely understandable: from the outside, the description sounds odd. This article tries to explain what EMDR is — without mystifying it or oversimplifying it.

What EMDR Is and Where It Comes From

EMDR stands for Eye Movement Desensitization and Reprocessing. It was developed by psychologist Francine Shapiro in the late 1980s and has since accumulated a substantial body of scientific evidence. The WHO recognizes it as one of the recommended treatments for post-traumatic stress disorder (PTSD).

What EMDR Does

When we experience something difficult but not traumatic, the brain integrates it more or less naturally. When something is traumatic, this integration process gets interrupted. The memory stays “frozen” in the activation state it was formed in — with all the emotion, physical sensations, and negative beliefs about oneself intact. Thinking about it years later can feel almost like reliving it.

EMDR works on those unprocessed memories. Bilateral stimulation — eye movements or other forms of alternating stimulation — seems to facilitate adaptive processing of these memories, allowing the nervous system to complete what was interrupted.

EMDR doesn’t erase memories. It helps the system process what got stuck, so the past can stop living in the present with the same intensity.

What It’s Used For

  • Complex trauma: repeated experiences of abuse, neglect, or dysfunctional environments.
  • Single-incident trauma: accidents, assaults, sudden losses.
  • Phobias and intense fears with an identifiable experiential origin.
  • Deeply held negative core beliefs.
  • Complicated grief.

What EMDR Is Not

It’s not hypnosis — the person is fully conscious throughout. It doesn’t erase memories. It’s not a quick fix for every problem. And it doesn’t replace therapy: it’s a tool within a broader process.
