Clinical Efficiency and Acceptability of EMDR and MOSAIC Therapy for PTSD.

Eye movement desensitization and reprocessing (EMDR) therapy is one of the therapies recommended by the World Health Organization (2013) to treat posttraumatic stress disorder (PTSD). Although efficient, repeated exposure to the traumatic memory may reduce its acceptability to patients. The therapy "eye movement and alternate stimulation for brain integration" (MOSAIC in French) was developed to improve acceptability and reduce pain by drawing on the patient's internal resources.

Sleep parameters improvement in PTSD soldiers after symptoms remission.

Eye movement desensitization and reprocessing (EMDR) is a psychotherapy for the treatment of posttraumatic stress disorder (PTSD). It is still unclear whether symptoms remission through EMDR therapy is associated with a beneficial effect on one of the PTSD symptoms, sleep disturbance. Our objective was therefore to study sleep parameters before and after symptom remission in soldiers with PTSD.

MOSAIC: A New Pain-Free Psychotherapy for Psychological Trauma.

Eye movements and alternating stimuli for brain integration (MOSAIC) is a promising but untested new therapy. Its four-step protocol is based on the effects of bilateral alternating stimulation (BAS) (as in eye movement desensitization and reprocessing therapy) on the brain. This solution-oriented therapy promotes experiencing solutions through bodily sensations.

Involvement of the cerebellum in EMDR efficiency: a metabolic connectivity PET study in PTSD.

Background: We recently reported an improvement of precuneus PET metabolism after EMDR therapy in military participants suffering from PTSD.

Objective: The aim of the present study was to investigate the metabolic changes of precuneus connectivity in these participants after such treatment.

Method: Fifteen participants with PTSD performed a brain 18F-FDG-PET sensitized by virtual reality exposure to war scenes, before and after EMDR treatment.

Cracking the EMDR code: Recruitment of sensory, memory and emotional networks during bilateral alternating auditory stimulation.

Introduction: The inability to extinguish a conditioned fear is thought to be at the core of post-traumatic stress disorder. Eye movement desensitization and reprocessing therapy has been efficacious for post-traumatic stress disorder, but the brain mechanisms underlying the effect are still unknown. The core effect of eye movement desensitization and reprocessing therapy seems to rely on the simultaneous association of bilateral alternating stimulation and the recall of the traumatic memory.
