What EMDR is, in plain words
EMDR stands for Eye Movement Desensitization and Reprocessing. It was developed almost 40 years ago, in 1987, by an American psychologist, Francine Shapiro. She noticed something on a walk one day: when her eyes moved from side to side while she thought about something upsetting, the thought lost some of its charge.
From that observation came a structured therapy. In EMDR, we bring to mind an old memory, or an old belief you can't seem to get out of, while your attention follows a gentle left-right rhythm. That rhythm is called bilateral stimulation. It can be eye movements, tapping, or sounds.
Something happens when we combine the two. The memory gets reprocessed. You don't forget what happened. But it stops hurting the way it used to, and what you believe about yourself because of it starts to change.
Why understanding isn't always enough
For decades, talking was considered the best way to heal. And talking helps with so many things. But for many people, understanding and talking aren't enough on their own. The insight is there, and the feeling doesn't change. We also learned that going over painful experiences again and again, without the right support, can sometimes reopen the wound rather than heal it.
Here is how I explain it to my clients.
When you and I talk in a session, we talk from a place of calm. We're using the front part of the brain, the part that is grounded, rational and well anchored in the present. From there, you know that the past is over. You know, objectively, that you are not useless, or the least lovable person in the room, or to blame for what happened.
But that knowledge doesn't reach below the surface. The moment something you see, hear or feel reminds you of what happened, you feel and believe exactly what you did back then. Your reasonable mind simply isn't available to you in that moment. And the beliefs stay too. You can know you are not worthless and still make choices, every day, as if you were. You can't talk yourself out of it. It feels cemented in.
What I see in my office is people who are tired of understanding their problem perfectly and still feeling stuck in it.
EMDR works differently. It creates a bridge between your calm, rational mind and the part of you that still holds the old experience. It lowers the gate between them, so we can revisit the memory and the belief together, and they can settle into something wiser, kinder and more accurate.
Researchers still don't fully agree on exactly why the left-right movement has this effect. What we do know, after decades of studies and many thousands of clients, is that it works.
