1. Jatzko, A., Ruf, M., & Schmitt, A. (2008, Mai). Durch EMDR normalisierte funktionelle verarbeitungsprozesse bei PTBS: Eine fMRT pilotstudie [EMDR normalized by functional processing in PTSD: An fMRI pilot study] . Poster präsentiert auf der 10. Jahrestagung der DeGPT Deutschsprachige Gesellschaft für Psychotraumatologie, Psychisches Trauma-korperliches Leiden, Basel, Schweiz.
Es existieren kaum Untersuchungen mittels funktioneller Bildgebung, die den Effekt psychotherapeutischer Verfahren und deren Auswirkungen auf das Gehirn eruieren. Eye-Movement-Desensitization and Reprocessing (EMDR) ist ein anerkanntes Verfahren zur Behandlung der posttraumatischen Belastungsstörung, jedoch wurde noch keine fMRT-Studie zu diesem Verfahren veröffentlicht. Diese fMRT-Studie soll erste Hinweise auf die Auswirkungen einer EMDR-Therapie auf die Informationsverarbeitung einer Patientin mit einer posttraumatischen Belastungsstörung (PTBS) zeigen.
The fMRI study was at the ZI in a SIEMENS VISION 1.5 Tesla MR scanner with a 2D/EPI-Sequence (3.43 mm x 3:43 in plane Resolution, 24 layers, 4 mm per layer, 1 mm gap) and a Repetition time of 2.94 s made. It was her description of her of the accident at the moment of impact in a block design alternating with a baseline condition (only MRI noise) presented. Each 8x block was presented for 19.8 sec. After this there is a EMDRBehandlung (2h), where there were violent reactions of the patient. After a 20th Break was repeated the fMRI procedure. The Analysis was performed by BrainVoyager QX 1.9, with a t-test (fixed effect) with a threshold of q <0.5 (corrected) as was assumed significant.

2. Shapiro, E. (2012). EMDR and early psychological intervention following trauma. Revue Européenne De Psychologie Appliquée/European Review of Applied Psychology, 62(4), 241-251. doi:10.1016/j.erap.2012.09.003.
Introduction: This article evaluates developments in the field of early psychological intervention (EPI) after trauma in general and the place of early eye movement desensitization and reprocessing (EMDR) intervention (EEI) in particular. The issues and dilemmas involved with EPI and EEI will be outlined; related research presented and the current status evaluated. Literature and clinical findings: Reviewing the literature and drawing on findings from initial research and case studies, the rationale and contribution that EMDR therapy has to offer is discussed relative to current evidence and theory regarding post-traumatic stress syndromes and trauma memories. The relative advantages of EEI will be elaborated. Discussion and conclusion: It is proposed that EEI, while trauma memories have not yet been integrated, may be used not only to treat acute distress but may also provide a window of opportunity in which a brief intervention, possibly on successive days, could prevent complications and strengthen resilience. Through the rapid reduction of intrusive symptoms and de-arousal response as well as by identifying potential obstructions to adaptive information processing (AIP), EMDR therapy may reduce the sensitisation and accumulation of trauma memories.

3. Yehuda, R. (2012, October). Epigenetics: What does it explain about trauma survivors?. Plenary presented at the annual meeting of the EMDR International Association, Arlington, VA .
Most persons who develop PTSD in the aftermath of exposure recover from trauma-related symptoms, but remain at risk for a recrudescence of symptoms. This suggests that there are aspects of the response to high magnitude trauma that are long-lasting, despite variations in symptom intensity over time. Current bio-behavioral models of PTSD fall short of explaining the apparent paradox of an enduring response on the one hand and symptom change over time on the other. However, this phenomenon can potentially be explained by epigenetic mechanisms. Epigenetics (literally: “epi” meaning “in addition to” genetics) refers to a heritable change in the genome that can be induced by environmental events and does not involve an alteration of DNA sequence. Such modifications reflect enduring changes in the function of the DNA that are caused by environmental exposures. These changes can alter gene function influencing its biological activity. This presentation will discuss evidence for such changes in PTSD, and will explain how such mechanisms explain many of the salient features of PTSD, including individual variation in responses to events of similar intensity (e.g., combat exposures), and the relative permanence of biological and psychological alterations associated with the disorder. Current models of stress, or even gene-environment interactions, only partially address the influence of prior exposure(s) on PTSD vulnerability and the long-lasting biological and psychological effects of trauma exposure. In addition, epigenetic modifications can be transmitted intergenerationally, both through the maternal and paternal lines. The implications of such changes as PTSD vulnerability factors will also be discussed.
