This research represents the first controlled treatment study of hypnosis and cognitive- behavioral therapy (CBT) of acute stress disorder (ASD). Civilian trauma survivors (N=87) who met criteria for ASD were randomly allocated to 6 sessions of CBT, CBT combined with hypnosis (CBT-hypnosis), or supportive counseling (SC). CBT comprised exposure, cognitive restructuring, and anxiety management. CBT-hypnosis comprised the CBT components with each imaginal exposure preceded by a hypnotic induction and suggestions to engage fully in the exposure. In terms of treatment completers (n=69), fewer participants in the CBT and CBT-hypnosis groups met criteria for posttraumatic stress disorder at posttreatment and 6-month follow-up than those in the SC group. CBT-hypnosis resulted in greater reduction in reexperiencing symptoms at posttreatment than CBT. These findings suggest that hypnosis may have use in facilitating the treatment effects of CBT for posttraumatic stress.

In this study, the authors investigated the relationship between acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) following cancer diagnosis. Patients who were recently diagnosed with 1st onset head and neck or lung malignancy (N=82) were assessed for ASD within the initial month following their diagnosis and reassessed (n=63) for PTSD 6 months following their cancer diagnosis. At the initial assessment, 28% of patients had ASD, and 32% displayed subsyndromal ASD. At follow-up, PTSD was diagnosed in 53% of patients who had been diagnosed with ASD and in 11% of those who had not met criteria for ASD; 36% of patients with PTSD did not initially display ASD. In this study, the authors question the use of the ASD diagnosis to identify recently diagnosed patients at risk of PTSD.

Stress, especially the extreme stress of traumatic events, can alter both neurobiology and behavior. Such extreme environmental situations provide a useful model for understanding environmental influences on human biology and behavior. This paper will review some of the evidence of brain alterations that occur with exposure to environmental stress. This will include recent studies using neuroimaging and will address the need for histological confirmation of imaging study results. We will review the current scientific approaches to understanding brain environment interactions, and then make the case for the collection and study of postmortem brain tissue for the advancement of our understanding of the effects of environment on the brain. Creating a brain tissue collection specifically for the investigation of the effects of extreme environmental stressors fills a gap in the current research; it will provide another of the important pieces to the puzzle that constitutes the scientific investigation of negative effects of environmental exposures. Such a resource will facilitate new discoveries related to the psychiatric illnesses of acute stress disorder and posttraumatic stress disorder, and can enable scientists to correlate structural and functional imaging findings with tissue abnormalities, which is essential to validate the results of recent imaging studies.

Although women are exposed to proportionately fewer traumatic events in their lifetime than men, they have a higher lifetime risk of post-traumatic stress disorder (PTSD). In addition to gender-differential rates of rape and sexual assault, including greater exposure to intimate partner violence, the preponderance of PTSD in women may be attributable to factors other than trauma type, such as sensitisation of stress hormone systems in response to early adverse experiences, inherent neuroendocrine factors, subjective interpretation of the event, and peritraumatic dissociation. Women with PTSD arguably experience a greater symptom burden, longer course of illness and have worse quality-of-life outcomes than men. An expanding knowledge base of the psychobiological alterations in PTSD is providing stimulus for the development of improved pharmacological and psychosocial treatment options. Recent randomised controlled studies conducted in large samples of women with chronic PTSD indicate that: (i) SSRIs have efficacy on all three symptom clusters of PTSD and should be used as first-line pharmacotherapy; and (ii) cognitive behavioural strategies (e.g. prolonged exposure treatment and cognitive processing) are effective in sexually and non-sexually assaulted women. Studies also suggest that female gender may be associated with better response rates to pharmacotherapy. Emerging empirical data on the potential usefulness of antiadrenergic agents and preventive cognitive behavioural treatments in managing acute trauma reactions and stemming the emergence of PTSD are paving the way for further work in this area. However, additional innovative treatments are needed for traumatised women and for female children/adolescents presenting with acute stress reactions and PTSD.

Of all the psychological complications that an individual is likely to present with when confronted with an exceptional event, the Post-Traumatic Stress Disorder is characterized by being progressive, frequent, invalidating, strongly associated with comorbidity, and having the tendency to become chronic if it is not detected clinically. By definition, it is threatening and produces an intense fear reaction. The traumatic event is a situation of extreme stress, not only capable of altering the physical and psychological homeostasis of the individual, but is also recognized as determinant in the aetiopathology of complications. The intensity of this distress can be identified clinically and physiologically, and is currently considered as an important risk factor for the development of PTSD later on, together with other pre-, peri- and post-traumatic factors. In fact, the most studied field is the therapeutic approach, in particular drug treatment, of the fully-constituted disorder, although this actually represents tertiary prevention. Even though primary prevention seems to concern Medicine very little, any prospect of performing secondary prevention should begin by rapid identification of the risk or vulnerability factors and should allow a population at risk from developing complications to be defined. Its potential therapeutic impact brings together psychotherapeutic and drug treatment, since it is only this combination that seems able to allow the most favourable clinical outcome to be achieved for an individual, who is confronted by an out-of-the-ordinary event. The aims of secondary prevention strategies are, for example, to reduce the incidence of acute PTSD in patients seen following the event. The benefits for the individual and for the society can easily be measured in terms of the consequences on his/her social, professional and family life, or in terms of cost. The usefulness of this prevention can also be measured by the possible ways that other conditions, comorbid to PTSD, are controlled, such as anxiety disorders, depression and substance abuse, for example. Secondary prevention strategies may also be aimed at determining the therapeutic impact, by preventing or moderating the appearance of an acute stress, or even by contributing in avoiding the onset of chronic PTSD. Psychopharmacology of the immediate and post-immediate disorders, however, remains a field which has been studied very little. Reduction or control of the high, prolonged level of hyperarousal phenomena or hypersensitization of the hypothalamo-pituitary axis, would contribute to the comfort of the individual, and would participate in the prevention of PTSD. Based on current knowledge of the neurobiology of trauma, we look into the existing and potential pharmacological possibilities. Even though benzodiazepines tend to have an important role, knowledge of other drugs and therapeutic groups is rapidly increasing. In this review, we will see that the efficacy of anti-adrenergic drugs and certain other anxiolytics is now well-documented, this opening the door to their use in the future. Other drug groups offer interesting, well-proven approaches, such as serotoninergic drugs, CRF or NPY antagonists, NMDA antagonists, anticonvulsants or other GABAergic agents. In view of this disorder, which represents a true public health problem, we consider that it is now possible to widen the horizons of our drug therapy, in combination with any necessary psychotherapeutic treatment, to reach the heart of the traumatic event, that often upsets the victims, both by the psychological suffering it induces, and the loss of his/her social, family and professional references and support structures.

Adjustment disorder is a diagnosis that is commonly used, particularly in primary care and general medical settings. However, there has been relatively little research done on this disorder. In this article, the author reviews the information that is available on the epidemiology, clinical features, validity, measurement, and treatment of adjustment disorder. She first reviews the historical development of the diagnosis from transient situational personality disorder in DSM-I to its current definition in DSM-IV. The author also considers similarities and differences in how adjustment disorder is defined in the DSM and ICD systems. The clinical features of the disorder that distinguish it from disorders such as major depressive disorder, generalized anxiety disorder, posttraumatic stress disorder, and acute stress disorder are described. The author highlights a number of the common controversies concerning adjustment disorder, especially criticisms that the diagnostic criteria are often poorly applied and that the disorder itself involves the medicalizing of problems of living. Evidence in support of the validity of the adjustment disorder diagnosis is reviewed and the author concludes that the findings support the content and predictive validity of the diagnosis. The author then discusses the epidemiology of adjustment disorders, their comorbidity with other conditions, including personality disorders, substance abuse, and suicidal behavior, and their treatment and outcome. The article concludes with a discussion of the special problems involved in evaluating for and measuring adjustment disorder.

Exposure techniques have now been used in the treatment of anxiety disorders for several decades. Although such techniques are a dominant feature of current therapies for disorders such as posttraumatic stress disorder and acute stress disorder, examination of their relative merits has been less studied. The purpose of this review is to suggest the usefulness of in vivo flooding in the treatment of posttraumatic stress. We discuss the relevant exposure literature by briefly examining the efficacy of these techniques in the treatment of anxiety. The theoretical and methodological limitations of investigations to date of exposure methods that have been used in posttraumatic stress treatment studies are then reviewed. We highlight the fact that in vivo flooding, an exposure technique that has been used to treat some anxiety-based disorders, has received scant clinical and research attention as a treatment for posttraumatic stress. A case is made for further study of in vivo flooding in the treatment of posttraumatic stress.

Disasters are tragic events that disrupt the normal functioning ofa community and overwhelm personal and community resources. The people who experience or simply witness traumatic events can be affected emotionally and develop a range of physical and emotional responses, which in turn can produce psychological, social, and physiological dysfunction. The challenge for health care providers is to recognize the range of emotions and to be able to identify when professional help is indicated. This article provides an overview of the human stress response and describes sources of stress that follow disasters, acute stress disorder, post-traumatic stress disorder, and interventions and resources used to care for victims after disasters.

Previous studies have suggested that the endocannabinoid CB1 receptor (ECBR) system is involved in stress. However, the nature of this association is complex. Here, we investigated the role of CB1 receptors in the response to stress by comparing the effects of various stress modalities in CB1-/- receptor deficient and wild-type mice, at adulthood and during early development. Response to acute stress was assayed by plasma corticosterone (CS) and adrenocorticotrophic hormone (ACTH), USVs and motor inhibition. The response to repeated stress was assessed by USVs and motor inhibition. Since repeated bell stress seemed to cause a cumulative fear in CB1 receptor knockout mice, these behavioral responses were also compared to those observed after a single severe stress (forced swimming). In wild-type, but not in CB1 receptor knockout mice, bell stress-induced elevations of ACTH and CS were significant. The first exposure to bell stress had no significant effect on USVs or mobility. Upon repeated exposures, significant suppression of USVs, together with behavioral inhibition, were observed in CB1 knockout but not in wild-type mice. Swim stress inhibited USVs in the knockout animals, and the profound motor inhibition displayed by all animals was greater and more prolonged in the CB1-/- mice. Since the knockout mice lack the CB1 receptor throughout pre- and postnatal life, the stress response in pups was also assayed (by separation-induced USVs). Wild-type pups displayed the characteristic developmental peak in USV emissions; it was completely lacking in knockout pups. We conclude that acutely, the absence of CB1 receptors reduces the neuroendocrine response and does not affect the behavioral response to moderate stress. However, upon repeated stress or acute severe stress, CB1 receptor deficiency causes persistent behavioral inhibition. Finally, the CB1 receptor plays a role in modulating the stress response from an early age. These observations suggest that CB1 receptors participate in the mediation of the stress response and that the absence of these receptors results in a greater vulnerability to stress. We suggest that the stress-induced endocrine and behavioral suppression in CB1 receptor deficient mice may serve as a model for some forms of post-traumatic stress disorder (PTSD). Further, the role of CB1 receptors in coping with stress is a lifelong function. Finally, although equivalent research has not been performed in human infants, the postnatal suppression of the stress response in CB1 receptor knockout pups may have implications when cannabinoid-based therapy is considered for children.

There is much interest in identifying people shortly after trauma exposure who will subsequently develop posttraumatic stress disorder (PTSD). This review outlines recent developments in early identification of trauma-exposed people who are at high risk for PTSD development, including the rationale, evidence, and limitations of the acute stress diagnosis as a predictor of chronic PTSD. The potential role of acute dissociative responses mediating development of PTSD is also reviewed. The available evidence suggests that whereas acute dissociation is an important factor in the acute stress response, many people develop PTSD in the absence of dissociative symptoms. The evidence suggests that dissociation needs to be considered in the context of other factors in the aftermath of trauma if optimal identification of high-risk individuals is to be achieved.
