EMDR is a set of standardized protocols that incorporates elements from many different treatment approaches. To date, EMDR therapy has helped millions of people of all ages relieve many types of psychological stress.
When a person is very upset, their brain cannot process information as it does ordinarily. Moments of trauma may become "frozen in time," and remembering traumatic moments may feel as bad as going through it the first time because the images, sounds, smells, and feelings haven’t changed. Such memories have a lasting negative effect that interferes with the way a person sees the world and the way they relate to other people.
EMDR seems to have a direct effect on the way that the brain processes information. Normal information processing is resumed, so following a successful EMDR session, a person no longer relives the images, sounds, and feelings when the event is brought to mind. You still remember what happened, but it is less upsetting.
Many types of therapy have similar goals. However, EMDR appears to be similar to what occurs naturally during dreaming or REM (rapid eye movement) sleep. Therefore, EMDR can be thought of as a physiologically based therapy that helps a person see disturbing material in a new and less distressing way.
Research has shown that EMDR can be an efficient and rapid treatment. Approximately 20 controlled studies have investigated the effects of EMDR. These studies have consistently found that EMDR effectively decreases/eliminates the symptoms of post traumatic stress for the majority of clients. Clients often report improvement in other associated symptoms such as anxiety. The current treatment guidelines of the American Psychiatric Association and the International Society for Traumatic Stress Studies designate EMDR as an effective treatment for post traumatic stress.
