This theoretical review highlights two misconceptions in the prevailing cognitive view of trauma-related disorders, specifically including PTSD. We see mental disorders such as PTSD as calling for mental explanations. In fact, trauma-related symptoms and disorders are inherently psychobiological. The bi-directional processes of psychoneuroimmunology explain why physical disorders are comorbid with stress. Diagnostic criteria for PTSD focus on sympathetically mediated "fight & flight" defenses, reflecting a belief that stems from Walter Cannon (1929, 1932). Actually, immobility defense states such as freeze and collapse are parasympathetically mediated; these immobility responses are preferred in situations of extreme threat (e.g., life-threat) when active defenses would increase the risk of death (e.g., in Complex PTSD). Together, active and immobility defense states contribute symptom variability that is neither predicted nor explained by the prevailing view. This evolutionary perspective has important implications for stress research, clinical practice, and diagnostic nosology.

This theoretical review considers controversy in the traumatic-stress field as an inevitable consequence whenever philosophical assumptions differ between opposing sides. Two contemporary examples of controversies in traumatology surround adoption of EMDR (and other new clinical methods), and the final report of the American Psychological Association's Working Group on memories for childhood sexual abuse. Both examples are discussed within the framework of an historical rift between researchers and clinicians. The concomitant involvement of non-scientific issues (e.g., stereotyping) and approaches to consensus are also discussed.

Bargh and Morsella begin this important article by noting that many psychological scientists view our unconscious mind as a shadow of our conscious awareness (e.g., equating unconscious with subliminal). They then review substantial evidence challenging this restricted view, and research which demonstrates the existence of relatively independent unconscious perceptual, evaluative, and motivational guidance systems. They conclude that unconscious action can precede reflextion. This view is relevant to an evolutionary perspective on our responses to traumatic events.

Lisa Feldman Barrett notes that laypeople and scientists believe that emotions are natural kinds. That is, we believe that we know emotions such as anger and fear when we see them. The scientific study of emotions rests on this assumption. This article reviews empirical evidence that is inconsistent with this assumption, and considers what moving past this assumption might mean for the scientific study of emotions. This article has important implications for the study of our responses to traumatizing experiences.

Edwin Blalock describes the common chemical language (i.e., neurotransmitters and cytokines) used by the central nervous system and the immune system, and the bidirectional communication between these systems that this common language implies. Our immune system may serve as a sixth sense, informing the central nervous system of entities such as bacteria and viruses that are imperceptible to the central nervous system. Bidirectional communication between our nervous and immune systems provides a path to understand observed comorbidity of stress-related physical disorders.
Article published in the journal CNS Spectrums, 9(9), 679-685.
Stefan Bracha suggests here that faintness evolved as a response to extreme inescapable threats. He argues that five defense states (listed in the title above) provide a more complete description of acute human responses to varied dangers and threats, than the prevailing "fight, flight & freeze". This evolutionary-based conception offers a more accurate account of stress responses, and also provides a way to understand the varied symptoms observed across (and within) individuals diagnosed with PTSD. Implications of this evolutionary perspectrive for the DSM-5 are briefly mentioned.
Article published in the International Body Psychotherapy Journal, 11(2), 2012.
Merete Holm Brandtbjerg describes the collapse defense state, which she calls hyporesponse. This state presents a clinical challenge because it does not call attention to itself. She goes on to describe hypoarousal and hyperresponse separately within the autonomic nervous system and within the musculature or connective tissue (I see such mis-matches of defense states as signs of dysregulation). Important insights in this article include the value of this response as a defense to stress or trauma, how hyporesponse might be experienced in your body, and practical ways to work with this state.

Brian Engdahl and colleagues interviewed a community sample of former prisoners-of-war (N = 262; WWII & Korea) living in the midwestern United States, comparing the incidence of posttraumatic stress disorder (PTSD) with other DSM Axis I disorders often found among trauma survivors. The most severely traumatized POW's had lifetime rates of 84% and current rates of 58% for PTSD; most of those with current PTSD were free from other Axis I disorders. Less than 10% of this sample was free of all PTSD symptoms. The authors conclude that PTSD is a normative and persistent consequence of exposure to severe trauma.

Julian Ford, at the National Center for PTSD, reports on important differences and similaries between the Posttraumatic Stress Disorder (PTSD) and Disorders of Extreme Stress (DESNOS) diagnostic categories, in a sample of 84 male military combat veterans seeking inpatient PTSD treatment. In this chronic sample, with depression and personalitiy disorders used as covariates, the two disorders were found to be comorbid but distinct post traumatic syndromes. Ford concludes that the combination of early childhood and atrocity trauma may best be understood in terms of DESNOS. Implications are discussed for assessment, classification, research and treatment. 56 references.
As published in the October 1998 issue of the Journal of Traumatic Stress, 11(4), 743-761.
Julian Ford investigated early trauma and DESNOS as contributing factors in treatment outcome, in this study of adult chronic PTSD inpatients. Although early trauma is correlated with a diagnosis of DESNOS, the authors found that DESNOS was a stronger predictor of treatment non-responding in this patient population. Implications for treatment planning are discussed. 74 references.

Diana Fosha summarizes research in affective neuroscience, attachment, and dyadic regulation, then introduces her Accelerated Experiential-Dynamic Psychotherapy (AEDP) approach to therapy, and discusses this method within the context of current research. Dyadic regulation of affective states, and the experience of intense emotion is illustrated through excerpts from two psychotherapy sessions; the power of affect is explored in development, psychopathology, and in psychotherapy. Dr. Fosha's chapter furthers the dialog between practice and clinically-relevant research. 111 references.

William Friedrich and colleagues at the Mayo Clinic summarize the normative development of sexual behaviors in over 11,000 children between 2 and 12 years. Sexual behavior was related to the child's age, maternal education, family sexuality, family stress, family violence, and hours/week in day care. A broad range of sexual behaviors are exhibited by children who there is no reason to believe have been sexually abused.

In this case control study of monozygotic twins discordant for trauma exposure, Mark Gilbertson and six colleagues investigate important questions about size of hippocampus and vulnerability to trauma. The authors found that severe PTSD twin pairs -- both trauma-exposed and unexposed -- had significantly smaller hippocampi. Their results indicate that pre-existing hippocampal volume constitutes an independent risk factor for development of trauma-related psychopathology, and show one way that individual differences in vulnerability for PTSD (given a traumatic exposure) may appear. About 50 references.

This version is a detailed summary of the published chapter, available on the internet for several years. Jim Goodwin gives a clear and well-written look at the long-term consequences of combat-stress for Vietnam veterans, and similarities and differences from other kinds of traumatic-stress reactions. Individual sections describe several PTSD symptoms particularly common within this population: depression, isolation, rage, alienation, survivor guilt, anxiety, nightmares, and intrusive thoughts.

Myron Hofer describes a state of prolonged motionlessness in several wild rodent species, provoked in response to the presence of a natural predator. This immobility state was accompanied by very low heart rate and a high incidence of cardiac arrhythmias. Hofer discusses the adaptive value of this defense state (i.e., collapse), and compares physiological characteristics of this state to those observed during syncope, expectation of attack, and sudden death. His article provides a basis in mammalian defensive behaviors for recognizing collapse as a human response to the most extreme types of stress (see Richter, below).

Ellert Nijenhuis, writing with colleagues Onno van der Hart and Kathy Steele, presents the most detailed explanation of their theory of structural dissociation as a response to traumatization. Describing dissociation as a failure to synthesize and personify terrifying experiences, this article explores the evolutionary and trauma-related origins of this response, addresses the increasing complexity of structural dissociation into secondary and tertiary forms that may occur in cases of chronic abuse and neglect, and summarizes recent psychobiological research concerning the theory. This provides a detailed theoretical rationale for the authors' phase-oriented treatment approach. 159 references.

This clinical article gives a detailed description of Frank Ochberg's approach towards therapy with trauma patients, and should be helpful to any clinicians working with this population. Individual sections discuss fundamental principles and techniques of posttraumatic therapy, including: education, discussing psychobiology, promoting holistic health, and psychotherapy. Two Appendices list proposed diagnostic criteria and symptoms for victimization disorder as a subcategory of traumatic stress.

In this article, Pat Ogden and Kekuni Minton describe their somatic (body) clinical approach to facilitate processing of unassimilated sensorimotor reactions to trauma; this sensorimotor sequencing, in turn, facilitates emotional and cognitive processing. Sensorimotor Psychotherapy requires that the clinician closely monitor sequential physical movements and sensations associated with motor impulses in the client -- muscular tension, trembling, changes in breathing, posture, and heart rate. The article describes physical defensive responses, "bottom-up" processing, and a modulation model; case examples illustrate the authors' clinical technique.

Bruce Perry discusses five neural systems involved in regulating a child's response to threat: the Reticular Activating System, Locus Coeruleus, Hippocampus, Amygdala, and Hypothalamic-Pituitary-Adrenal Axis, and then describes the clinical presentation and altered neurobiology of children exposed to violence. Heartrate data and gender differences are presented from children at the Branch Davidian' s Ranch Apocalypse compound.

Bruce Perry and his colleagues argue that infants and young children may be more vulnerable to traumas than adults -- that they are not resilient, but malleable. They consider neurobiological consequences of repeated dissociative or hyperarousal responses on developing brain organization, and conclude that the more plastic developing brain may be more vulnerable to disruptions related to these responses. Evolutionary advantages of gender differences in responses to trauma (hyperarousal by males; dissociation in females) are considered briefly, and clinical implications are discussed. Includes about 70 references.

Stephen Porges introduces his Polyvagal Theory to explain differing functions of two primary medullary source nuclei of the vague: the nucleus ambiguus (NA) and the dorsal motor nucleus (DMNX), responsible for respiratory sinus arrhythmia (RSA) and heart rate, respectively. He speculates that mammalian brainstem organization may be characterized by a ventral vagal complex (including NA) related to processes associated with attention, motion, and emotion. Various medical disorders may stem from competition between DMNX and NA. 105 refs.

In this methodological article, John Reid describes some common problems inherent when research with trauma victims and control subjects is initiated after disastrous events. He then proposes that long-term longitudinal studies may help shed light on these problems when subjects experience traumatic events during their research participation (e.g., crime, divorce, or natural disaster). Difficulties in collaboration with ongoing longitudinal/developmental studies during disaster situations are discussed, and suggestions offered.

Curt Richter revists the phenomenon of "Voodoo Death", investigated previously by Walter B. Cannon. Cannon had presumed that this form of suddon death would arise from an abundance of sympathetic activity. However, Richter shows here that death stems from overactivity of the parasympathetic system, likely experienced as hopelessness or mental defeat. Together with Hofer's later study with mammals (see above), Richter's work provides a solid basis for recognizing that the defensive state of collapse, devoid of sympathetic activity, can also be a human response to overwhelming threat.

In this classic article, W. H. R. Rivers writes about suppression and dissociation of traumatic combat experiences by World War I veterans, and his clinical observations that avoidance of traumatic memories -- the recommended treatment of the time -- interfered with recovery from "shell shock" or "war neurosis". This historical article is significant in the development of our scientific and clinical views about trauma responses and effective treatment. Dr. Rivers views on the effective treatment of what we now call PTSD were far ahead of his time, and issues addressed in this 1918 article remain controversial today.

In this book, Dr. Rivers explores theoretical aspects of his clinical experiences, at Maghull and Craiglockhart War Hospitals, treating "shell shock" and "war neuroses" among soldiers traumatized in WWI combat. His insight that avoidance of traumatic experiences does not assist recovery was prescient, and he saw dissociation as one type of suppression -- thus distinguishing distinct avoidance strategies. Rivers discusses self-preservation and "danger instincts" stirred during trauma in conjunction with Freud's ideas about the unconscious; this placed psychotherapy, especially for the traumatic form of "psycho-neuroses", within the theoretical framework of biology.

Dr. Robert Scaer examines dissociation and PTSD from the perspective of a neurologist. In this speculative article, he describes dissociation in terms of the freeze/immobility response observed in animals facing overwhelming threat. He also proposes a model of PTSD linked to autonomic dysregulation -- and maintained by kindling, dorsal vagal tone and endorphinergic rewards -- contributing to further dissociation. Finally, the autonomic dysregulation underlying dissociation and PTSD is discussed in the context of a diverse set of chronic diseases of unknown origin. 74 references.

In the first part of a two-part review, Allan Schore reviews psychoneurobiological mechanisms underlying infant mental health and successful adaptation. He integrates attachment data on dyadic affective communications, developmental neuroscience research on the right brain and stress psychophysiology, and developmental psychopathology perspectives on psychopathogenesis. This provides an overview of healthy development: connecting attachment theory, stress regulation, and infant mental health. Schore also describes the neurobiology of a secure attachment, and development of the right brain, early limbic system, and orbital frontolimbic regions, suggesting that normal orbitofrontal and right brain development is connected to adaptive mental health. 379 references.
Published in Infant Journal of Mental Health, 2001, 22, 201-269.
In the second part of his two-part interdisciplinary review, Allan Schore focuses on severe attachment failures, impairments in early development of the right brain's stress coping systems, and maladaptive infant mental health -- suggesting direct connections between traumatic attachment, inefficient right brain regulatory functions, and both maladaptive infant and adult mental health. He describes the neurobiology of infant trauma, neuropsychology of a disorganized / disoriented attachment pattern (associated with abuse and neglect), trauma-induced impairments of a regulatory system in the orbitofrontal cortex, links between orbitofrontal dysfunction and a predisposition to posttraumatic stress disorders, neurobiology of the dissociative defense, effects of early relational trauma on enduring right hemispheric function, and offers some implications for early intervention. 450 references.

In a review article written specifically for clinical and research traumatologists, Allan Schore sketches developmental precursors of complex PTSD and dissociative symptoms in the effects of early relational trauma on the developing central and autonomic nervous system. Early traumatic attachments negatively impact right brain development, producing structural changes that lead to inefficent stress coping mechanisms -- the core of posttraumatic stress disorders in infants, children, and adults. Schore makes a strong case that early intervention prevention programs can reduce intergenerational transmission of trauma-related disorders across the lifespan. 246 references.

Fredric Schiffer, M.D., reviews literature and hypothesizes that psychological traumas are associated more with one cerebral hemisphere than the other, and concludes that the ultimate aim of psychiatric care then becomes the teaching of the mental entity associated with this troubled hemisphere that it is now safer and more valued than it had been at the time of the trauma. He summarizes anecdotal evidence indicating that lateralized sensory stimulation can be used as an effective adjunct to psychotherapy, and describes the practical application of this theory to psychotherapy. PDF format; 50 references.

Kathy Steele and colleagues address the issue of dependency in chronically traumatized patients -- individuals often diagnosed with Bipolar Personality, Complex PTSD, or Dissociative Disorders. They first discuss the concept of dependency, exploring its origins in attachment difficulties and questioning prevailing beliefs before describing its relationship to structural dissociation and countertransference in psychotherapy. Then, using the theory of structural dissociation, the authors offer practical strategies to help clinicians manage insecure dependency within the therapy context. 129 references.
This is a version of an important chapter from Valent's 1998 book, From Survival to Fulfillment: A framework for the life-trauma dialectic, published in Philadelphia by Bruner/Mazel.
Paul Valent describes eight survival strategies in response to trauma -- "stress responses which include specific adaptive and maladaptive, biological, psychological and social constituents". Valent's survival strategies evolved as discrete phylogenetic templates to aid survival following specific stressors. Together, survival strategies offer a framework for categorizing classes of traumatic responses and events beyond PTSD's typical fight or flight responses. When trauma responses are unsuccessful, this framework may also help clarify differences that are important in treatment.

Onno van der Hart and Danny Brom present an overview of relevant literature on amnesia among survivors of the Holocaust. Following Janet's (1893/1901) continuum of localized-, selective-, and generalized amnesia, they describe several cases of survivors' trauma-induced amnesia of the Holocaust (with or without dissociative re-experiencing). In conclusion, the authors discuss reasons for the lack of research attention to this complex issue, possible causes of amnesia among Holocaust survivors, and the absence of delayed recall in this population. 57 references.

Onno van der Hart and Paul Brown review the use of "abreaction" in treating traumatic memories from Breuer and Freud through World Wars I and II, Vietnam, and in contemporary times. After tracing the historical and theoretical roots of two contradictory models concerning the nature and treatment of traumatic memories (dissociation/integration and abreaction/repression), the authors critically re-evaluate abreaction, and conclude that Janet's model of dissociation provides a preferable basis for phase-oriented treatment of the more complex traumatic-stress disorders. 103 references.

Onno van der Hart and Barbara Friedman review Pierre Janet's writings on hysteria and dissociation over a 30-year period, summarizing their central concepts. Janet was an important figure in early studies on dissociation and hysteria before hypnosis fell into disrepute, but his writings, many in French, are not well known in the US. Seven books are reviewed here; they focus primarily on classification and case descriptions. 94 references.

Disturbances in a sense of reality and time are especially dramatic in trauma-induced disorders, including dissociative identity disorder (DID). Observing that therapeutic change involves reorganizing the patient's experience of reality and time, Onno van der Hart and Kathy Steele describe therapeutic approaches that can assist this reorganization, within their phase-oriented treatment model. They integrate Pierre Janet'scontributions regarding time disturbances with more contemporary work relating time disturbances to trauma, and offer case examples. 52 references.

Onno van der Hart and colleagues integrate Pierre Janet's dissociation theory with contemporary trauma-based models of therapy. They begin by describing multiple personality disorder (now DID) as a disorder of non-realization, and then explore the nature of traumatic memories and the dissociative reactions they evoke, before presenting a phase-oriented treatment model for trauma-focused therapy with dissociative patients. Their non-abreactive treatment approach is appropriate for resolution of traumatic memories in adult survivors of chronic childhood abuse. 118 references.

Onno van der Hart and colleagues explore traumatic dissociation from descriptive, structural and functional perspectives. This article deepens our understanding of dissociation -- including perceptual, sensory, and motoric (somatoform) symptoms along with the cognitive (psychoform) symptoms in the DSM. Quotes from early writers dramatically illustrate various positive and negative dissociative symptoms in WWI combat soldiers. The authors emphasize the dissociative nature of somatoform symptoms seen in contemporary PTSD patients, and relate early observations by Charles S. Myers and by Pierre Janet to recent work by Ellert Nijenhuis and others. 111 references.

Repetition of traumatic experiences can occur on behavioral, emotional, physiologic, and neuroendocriniologic levels, but invariably causes suffering. In this 1989 article, Bessel van der Kolk describes the diversity of traumatic re-enactments, and addresses relationships to social attachment and separation, traumatic bonding, state-dependent learning, addiction to trauma, sex differences, and biological responses to trauma. Treatment implications are also discussed. 147 references.

Bessel van der Kolk reviews memory for traumatic events in this article. He discusses limbic system involvement in stress responses, psychobiological and developmental factors influencing how traumatic memories may be consolidated in the brain, and neuroendocrine abnormalities associated with PTSD. This article provides an excellent and very clear description of many aspects of memory for traumatic events, and it includes extensive references. Two tables and two figures are not available in this version. Includes 134 references.

In this article, Bessel van der Kolk and Rita Fisler review differences between memories of traumatic vs. stressful events and summarize evidence implicating dissociation as an important mechanism in the formation of PTSD. The authors also present results from an exploratory interview study, indicating that subjects (N=46) with PTSD initially retrieve traumatic memories as fragmentary dissociated elements (such as visual, olfactory, or affective experiences), followed by gradual emergence of a personal narrative (explicit memory). Includes 78 references.

This article reports results from the DSM-IV Field Trial for PTSD demonstrating a complex PTSD syndrome in people traumatized at an early age, or suffering from prolonged interpersonal trauma. Dissociation, somatization, and affect dysregulation represent a chronic adaptation to emotional trauma, and characterize complex PTSD (e.g., DESNOS). Clinicians should understand how complex trauma must be treated differently from acute or "simple" PTSD. The authors discuss implications for treatment and for PTSD diagnostic criteria. Includes four tables and about 90 references.

This article considers PTSD as a biological disorder, and discusses the roles of developmental level, memory, and dissociation in its formation. Bessel van der Kolk and his colleagues review the symptomatology of PTSD in detail, and describe three principle components of treatment, before turning to specific tasks guiding psychotherapeutic interventions including group therapy and psychopharmacological approaches. Two Tables summarize symptoms of simple PTSD and additional features associated with the proposed diagnosis of complicated PTSD. Includes about 70 references.

In this commentary article, Rachel Yehuda and Seymour Antelman propose five criteria that should be fulfilled by any animal model of PTSD. They describe an animal model based on time-dependent sensitization (TDS), and discuss alternative models involving learned helplessness and inescapable shock. Comparing these models with respect to their proposed five criteria for this disorder, the authors conclude that the TDS model best fits characteristics of PTSD. About 50 references.
