EMDR stands for Eye Movement Desensitization and Reprocessing. The name is a mouthful, and the acronym doesn’t clarify much. What it describes is a structured, evidence-based therapy for trauma that uses bilateral stimulation — typically eye movements, but sometimes tapping or auditory tones — to help the brain reprocess distressing memories.
Why do traumatic memories feel different?
When you experience something overwhelming — an accident, an assault, a sudden loss, a threatening event — the brain sometimes can’t fully process what happened. The memory gets stored differently than ordinary memories. It retains the emotional and physical charge it had at the moment it happened. When something triggers that memory, you don’t just remember it — you feel it again, in your body, with much of the original intensity.
This is what distinguishes traumatic memory from ordinary memory: it doesn’t fade the way most memories do. It stays raw.
How does EMDR work?
EMDR works by engaging the brain’s natural memory processing system while you hold the traumatic memory in mind. The bilateral stimulation — usually the therapist moving their fingers back and forth in front of your eyes while you follow them — appears to activate the same processing that happens during REM sleep, when the brain consolidates and integrates experiences.
EMDR doesn’t erase the memory. What changes is the emotional charge attached to it. After successful processing, the memory becomes something that happened — not something that is still happening to you.
What happens during an EMDR session?
EMDR is structured. It doesn’t involve free-associating about your past or lengthy verbal analysis of what happened. A typical processing session involves:
- Identifying a target memory and the emotions, body sensations, and negative beliefs associated with it
- Sets of bilateral stimulation (eye movements, tapping, or tones), each followed by a brief check-in
- Processing what came up during the set — which might be other memories, emotions, images, or insights
- Continuing until the distress level of the memory is significantly reduced and a more adaptive belief about the event is established
What kinds of trauma can EMDR help with?
EMDR was originally developed for PTSD and has the strongest evidence base for trauma from specific events — accidents, violence, sexual assault, workplace incidents, sudden loss. It has also been used effectively for panic disorder, phobias, and other conditions where specific distressing memories or experiences are driving current symptoms.
It is not the right tool for every clinical situation, and it requires careful preparation — both client and therapist need to assess readiness before processing work begins. But for adults with specific traumatic experiences that haven’t resolved with time, EMDR is often a more direct path to relief than years of talk therapy.
Frequently asked questions
What does EMDR stand for?
EMDR stands for Eye Movement Desensitization and Reprocessing. It is an evidence-based therapy that uses bilateral stimulation — usually guided eye movements, tapping, or tones — to help the brain reprocess distressing memories.
Can EMDR therapy be done online?
Yes. EMDR can be delivered effectively via telehealth, and there is a strong research base supporting online delivery. Bilateral stimulation is adapted for screen-based sessions. I work with clients in California and Colorado via telehealth.
How many EMDR sessions does it take to see results?
It depends on the complexity of what’s being processed. For a single, well-defined traumatic event in someone who is otherwise stable, research shows reprocessing can take 1–6 sessions (not including assessment and preparation). Complex or repeated trauma may require considerably more time, and preparation work varies by person. I’ll give you an honest read on the likely timeline for your situation.
