EMDR for trauma and PTSD: what the research says

In studies, EMDR eased long-lasting PTSD symptoms in adults, but reviewers rated the quality of the evidence as very low. Other uses, such as grief or stress, are not well studied.

What a session is

EMDR (eye movement desensitisation and reprocessing) is a structured talking therapy for distressing memories. While you briefly bring a memory to mind, the therapist guides side-to-side eye movements, or uses taps or tones.

What the research says

• Trauma and PTSD: In studies, EMDR eased long-lasting PTSD symptoms in adults, and the NHS lists it as a treatment for PTSD. But many studies were small, Cochrane rated the quality of the evidence as very low, and more people stopped early than on a waiting list. Some evidence it may help · NHS, 2026 · Cochrane, 2013
• Soon after a frightening event: Research on therapies started soon after a trauma, including EMDR, is of low or very low certainty. It has not clearly shown that they reduce PTSD symptoms. Limited evidence · Cochrane, 2019
• Low mood, worry, stress, grief, menopause and pain: NHS pages describe EMDR as a therapy for traumatic memories and list it as a treatment for PTSD. We found no good studies of it for these needs. No good evidence yet · NHS, 2025 · NHS, 2026

This page is about adults. For children and teenagers with PTSD, the best research evidence is for CBT (cognitive behavioural therapy). Cochrane, 2012

Going back over painful memories can make you feel worse for a while, so tell your therapist if it does. Like any talking therapy, EMDR can have unwanted effects. IQWiG, 2023
