Facts about Eye Movement Desensitization and Reprocessing
- 10
Memory reconsolidation during EMDR processing allows the brain to integrate fragmented trauma memories into existing autobiographical narratives, reducing their emotional charge.
- 09
Eye movement speed during EMDR processing typically ranges from 20 to 30 saccades per second, matching the pace of rapid eye movement sleep when the brain consolidates memories.
- 08
EMDR treatment outcomes show comparable efficacy to cognitive-behavioral therapy for specific phobias, with phobia symptom reduction observed in as few as one to three sessions.
- 07
Neuroscientists using functional MRI imaging have observed increased activation in the prefrontal cortex and decreased amygdala activity during EMDR processing compared to baseline trauma recall.
- 06
Approximately 30 randomized controlled trials have demonstrated EMDR's efficacy for treating anxiety disorders, depression, and phobias beyond its established use for PTSD.
- 05
In 2013, the Department of Veterans Affairs officially designated EMDR as an evidence-based treatment for combat-related PTSD alongside cognitive processing therapy and prolonged exposure.
- 04
The eight-phase EMDR protocol includes history-taking, preparation, assessment, desensitization, installation, body scan, closure, and reevaluation across multiple sessions to comprehensively address traumatic memories.
- 03
Bilateral stimulation through rapid eye movements, tapping, or auditory tones during EMDR processing is theorized to activate both brain hemispheres simultaneously to facilitate trauma memory processing.
- 02
Clinical trials demonstrate that EMDR produces significant trauma symptom reduction in 80-90% of single-trauma PTSD patients within 3-6 sessions.
- 01
Francine Shapiro developed Eye Movement Desensitization and Reprocessing in 1987 after noticing her own eye movements reduced distress while processing traumatic memories.
