EMDR is an evidence-based therapy based on the idea that traumatic memories are stored in the brain differently than normal memories and that EMDR can help to “process” these memories and reduce their negative impact. During EMDR therapy, the person is asked to focus on a traumatic memory while the therapist guides their eye movements (or other forms of bilateral stimulation) back and forth. This is thought to mimic the rapid eye movements that occur during REM sleep and to help the brain process the traumatic memory. The person is also asked to focus on different aspects of the traumatic memory, such as their feelings and thoughts about the event, and to rate the level of distress associated with the memory. As the person recounts the traumatic memory, their level of distress should decrease. The therapist will also teach the person coping strategies and skills to help them manage their symptoms and reduce their reactions to triggers.
