What is EMDR therapy? Meaning, phases and evidence
EMDR stands for Eye Movement Desensitization and Reprocessing. It is a structured psychotherapy that works with distressing memories using dual attention and bilateral stimulation within a clinical treatment plan.
EMDR is a structured psychological therapy originally developed for trauma. It is not simply eye movements: it includes assessment, preparation, target-memory work, processing, closure and reevaluation.
What happens in EMDR
A person briefly attends to parts of a memory while following alternating stimulation—usually eye movements, tones or taps. The therapist guides the process and monitors distress, associated beliefs and physical sensations.
Exactly how EMDR produces change is still being investigated. Evidence for outcomes should be kept separate from theories about the mechanism.
The eight phases
The standard protocol covers history and treatment planning, preparation, assessment, desensitization, installation, body scan, closure and reevaluation. Processing is not automatically part of every appointment.
- History and treatment planning
- Preparation and stabilization resources
- Assessment and target-memory processing
- Safe closure and later reevaluation
Where the evidence is strongest
WHO and NICE guidelines include EMDR among psychological interventions for adults with PTSD. This does not mean that it works for every person, symptom or diagnosis. Evidence for other uses may be smaller, mixed or more dependent on individual circumstances.
What to look for in a therapist
Check professional eligibility, EMDR-specific training, supervision and experience relevant to your situation. A responsible therapist discusses limitations and alternatives and assesses whether the approach is suitable for you.
Frequently asked questions
Is EMDR hypnosis?
No. They are different interventions. During EMDR you remain awake, oriented and able to stop.
Do I have to describe the trauma in detail?
Not necessarily. EMDR can be used without a long detailed narrative, although the therapist still needs enough information to assess and plan safely.
Does EMDR erase memories?
No. The aim is not to remove a memory but to reduce distress and change how it is experienced or integrated.
