1 Neuroscience of Trauma

2 Trauma genesis Repeated activation of threat-response system that drives REACTIVE ADAPTATION & MITIGATION Nervous system becomes CHRONICALLY activated and CHANGES its structure and function Activation does NOT require abuse, abandonment, physical or sexual hurts—just the REPEATED perception of threat or a stress filled environment is adequate There are behaviors that are common and predictable when the survival system is dominant (usually seen as WRONG or BAD vs. ADAPTIVE Rhoton R. & Gentry E. 2016

3 Developmental Trauma Disorder
A. Exposure 1. Multiple or chronic exposure to one or more forms of developmentally adverse interpersonal trauma (abandonment, betrayal, physical assaults, sexual assaults, threats to bodily integrity, coercive practices, emotional abuse, witnessing violence and death). 2. Subjective Experience (rage, betrayal, fear, resignation, defeat, shame). Bessel A. van der Kolk, MD

4 Developmental Trauma Disorder
B. Triggered pattern of repeated dysregulation in response to trauma cues Dysregulation (high or low) in presence of cues. Changes persist and do not return to baseline; not reduced in intensity by conscious awareness. •Affective •Somatic (physiological, motoric, medical) •Behavioral (e.g. re-enactment, cutting) •Cognitive (thinking that it is happening again, confusion, dissociation, depersonalization). •Relational (clinging, oppositional, distrustful, compliant). • Self-attribution (self-hate and blame) Bessel A. van der Kolk, MD

5 Developmental Trauma Disorder
C. Persistently Altered Attributions and Expectancies •Negative self-attribution •Distrust protective caretaker •Loss of expectancy of protection by others •Loss of trust in social agencies to protect •Lack of recourse to social justice/retribution •Inevitability of future victimization Bessel A. van der Kolk, MD

6 Developmental Trauma Disorder
D. Functional Impairment •Educational •Familial •Peer •Legal •Vocational Bessel A. van der Kolk, MD

10 Figure 1A schematic of the human brain illustrating how the limbic system is involved in posttraumatic stress disorder (PTSD). The prefrontal cortex (PFC) and the hippocampus both have dense connections to the amygdala, which is important for conditioned fear and associative emotional learning. The PFC is thought to be responsible for reactivating past emotional associations and is decreased in both responsiveness and density. The hippocampus is thought to play a role in explicit memories of traumatic events and in mediating learned responses to contextual cues; in PTSD, the hippocampus is decreased in volume and responsiveness to traumatic stimuli. The top down control of the amygdala by the hippocampus and PFC might result in the increased activation of the amygdala, as is observed in subjects with PTSD. The end result of these neuroanatomical alterations is increased stress sensitivity, generalized fear responses and impaired extinction. Other regions including the anterior cingulate cortex, the orbitofrontal cortex, the parahippocampal gyrus, the thalamus and the sensorimotor cortex also play a secondary role in the regulation of fear and PTSD.

12 HEALING OF TRAUMA: RESEARCH & BEST PRACTICES
Emotion regulation strategies Narration of trauma memory Cognitive restructuring Anxiety and stress management (imaginal exposure, etc.) Interpersonal Skills (therapeutic alliance) Psychoeducation Meaning making Rhoton R. & Gentry E. 2016

13 Common elements trauma approach (ceta) “ACTIVE INGREDIENTS”
Relaxation: learning specific ways to calm the body Cognitive-Emotive Coping: learning how thoughts, feelings, and behavior are interconnected. Exposure-Trauma Memories/In-Vivo: process trauma in a SAFE PLACE Cognitive Restructuring: learning how to change “stuck thoughts” that are keeping distress going Behavioral Activation: planning and participation in pleasurable activities Problem Solving: learning specific way to come up with realistic solutions to problems Rhoton R. & Gentry E. 2016

15 The empowerment & resilience structure: an active ingredients approach
Preparation & Relationship Psychoeducation & Self-Regulation Integration & Desensitization Post-Traumatic Growth & Resilience Rhoton R. & Gentry E. 2016

16 The empowerment & resilience structure: an active ingredients approach
Preparation & Relationship Orientation and Acculturation around therapy process Discovering capacities and strengths while instilling faith and hope in the therapy process. GIVING CHOICES throughout treatment Formal and informal assessments used to increase relationship and connection (e.g. Adverse Childhood Experiences, also PCL, Assessing patterns and developing global goals that will be fine-tuned through the process Rhoton R. & Gentry E. 2016

17 The empowerment & resilience structure: an active ingredients approach
II. Psycho-Education and Skills Building Teach mechanics of the Threat-Response System Creating a common language to enhance ease of discussion and relational connection Teach impact of environment Convert discussions of anger, sadness, fear, etc. to physiological dysregulation Normalize internalize negative messages, perceptions of self, others and the world Normalize relationship, emotional and cognitive patterns Explore meaning of behavior Self-Regulation skills Rhoton R. & Gentry E. 2016

18 The empowerment & resilience structure: an active ingredients approach
III. Integration & Desensitization Use of various models: from EMDR to Somatosensory, EFT, Experiential & Creative/Art Therapies Elements Explain that in the beginning it is your JOB as the clinician to keep the BRAKES ON so that things don’t go too FAST. Titration is KEY. Creating narratives that can be expanded as needed and in the process lessen the reactivity to the events Normalize difficulties, unwanted emotions, thoughts, behaviors and beliefs Focus on discovering and highlighting strengths and capacities Mourning and working through grief Rhoton R. & Gentry E. 2016

19 The empowerment & resilience structure: an active ingredients approach
IV. Post-Traumatic Growth & Resilience Work Use of various models: from EMDR to Somatosensory, EFT, Experiential & Creative/Art Therapies Elements of Post-Traumatic Growth Consolidate change in the Perception of SELF Consolidate change in the Interpersonal Relationship Consolidate change in the Philosophy of Life Core Features of Resilience Relating Others, reconnecting or creating new connections Exploring New Possibilities Intentional Applications of Personal Strengths Spiritual Change or Re-Orientation Appreciation of Life even when faced with stressors Rhoton R. & Gentry E. 2016
