R5 - Neurobiology of complex trauma and dissociative disorders and research update 
Content Level: Advanced

Contributors: Su Baker, MEd, Joan Turkus, MD, John O’Neil, MD

Module Description
This module explores research on the neurobiology of trauma and dissociation, the validity of the diagnosis, as well as ongoing research into treatment of those with complex trauma and dissociative disorders. The high correlation between early and severe trauma and neglect in the developmental histories of people with complex posttraumatic and dissociative disorders has inspired much research into the underlying neurobiology. How do trauma and neglect during development affect normal neurobiology? How do genetics, developmental adversity, and their interaction (genetic expression – epigenetics) lead to different neurobiological pathways that ultimately give rise to various clinical expressions, such as complex posttraumatic pathology with and without significant dissociation, and the various dissociative disorders themselves? Research into treatment will focus especially on the TOP DD (Treatment of Patients with Dissociative Disorders) study, now past its 6th year of ongoing research. Specialized phasic, dissociation-focused treatment in this population has shown significant reductions in stressors, sexual revictimization, and psychiatric hospitalizations, and improved global functioning, safety, and quality of life. 

Objectives
1.    Describe how difference patterns of trauma and neglect give rise to different sets of neurodevelopmental effects
2.    Examine and discuss the research that underlines the validity of the diagnosis of DID
3.    Describe different neurobiological substrates of different categories of mental functioning across different diagnoses
4.    Discuss how treatment approaches to complex posttraumatic and dissociative pathologies may be statistically researched and tested
