Trauma- and stressor-related disorders occur following exposure to a traumatic or other stressful event. They differ according to the timing of exposure and age at manifestation. Post-traumatic stress disorder (PTSD) develops following exposure to actual or threatened death, serious injury, or sexual assault. Intrusions, distressing dreams, dissociative reactions (flashbacks), intense psychological distress, and physiological stress responses at exposure to internal of external cues that symbolize aspects of the traumatic event are typical for PTSD. Behaviourally, PTSD reflects a strategy of defence involving avoidance, attentive immobility, withdrawal, aggressive defence, appeasement, and tonic immobility, some of which are ancient vertebrate heritage. These defence mechanisms are preceded by heightened vigilance and risk assessment. Persistent stress responses often occur when important biosocial goals had been thwarted by the traumatic event. Species with long life-history patterns may be more vulnerable to developing PTSD than species with short life cycles.

ABSTRACTThe predisposition of Autism Spectrum Disorder (ASD) to Post-Traumatic Stress Disorder (PTSD) remained to be established. Here, we show that exposure to a single mild stressful event induces maladaptive memory, which recapitulates all features of PTSD, and is associated with the broad dysfunction of the prefrontal-hippocampo-amygdalar network. Using optogenetics, we demonstrate that prefrontal cortex hyperactivation triggers this PTSD-like memory. Finally, we show that recontextualization of the traumatic event normalizes maladaptive memory in ASD conditions. Overall, this study provides the first direct demonstration that ASD represents a risk factor for PTSD and uncovers new mechanisms that underlie pathological memory formation.

SYNOPSISAcute stress responses were investigated in head injured (N = 38) and non-head injured (N = 38) motor vehicle accident victims immediately following their trauma. Results indicated that amnesia of the traumatic event was associated with less acute post-traumatic stress, intrusive symptoms, perceived injury, and fear of future risk. A proportion of head injured patients reported intrusive and avoidance symptoms despite being amnesic of their trauma. Findings are discussed in terms of the differential post-traumatic adjustment of head injured and non-head injured traumatized patients.

BackgroundPain and post-traumatic stress disorder (PTSD) are frequently co-morbid in the aftermath of a traumatic event. Although several models attempt to explain the relationship between these two disorders, the mechanisms underlying the relationship remain unclear. The aim of this study was to investigate the relationship between each PTSD symptom cluster and pain over the course of post-traumatic adjustment.MethodIn a longitudinal study, injury patients (n=824) were assessed within 1 week post-injury, and then at 3 and 12 months. Pain was measured using a 100-mm Visual Analogue Scale (VAS). PTSD symptoms were assessed using the Clinician-Administered PTSD Scale (CAPS). Structural equation modelling (SEM) was used to identify causal relationships between pain and PTSD.ResultsIn a saturated model we found that the relationship between acute pain and 12-month pain was mediated by arousal symptoms at 3 months. We also found that the relationship between baseline arousal and re-experiencing symptoms, and later 12-month arousal and re-experiencing symptoms, was mediated by 3-month pain levels. The final model showed a good fit [χ2=16.97, df=12, p>0.05, Comparative Fit Index (CFI)=0.999, root mean square error of approximation (RMSEA)=0.022].ConclusionsThese findings provide evidence of mutual maintenance between pain and PTSD.

Post-traumatic stress disorder (PTSD) continues to be one of the most common mental health disorders in the United States and may occur in response to traumatic experiences. Currently, there are no interventions that prevent the development of PTSD. L-Theanine (L-Th), a major compound in green tea has been found to decrease anxiety and prevent memory impairment and may have potential effects in the prevention of PTSD. Sixty rats were divided into six experimental groups: control vehicle, control L-Th, control naïve, PTSD vehicle, PTSD Pre-L-Th (prophylactic), PTSD Post-L-Th (non-prophylactic). PTSD was induced by a 3-day restraint/tail shock stress model. The effects of L-Th on neurobehavior were evaluated by Elevated Plus-Maze (EPM), Morris Water Maze (MWM), and Forced Swim Test (FST). Our study found that the total food intake weight of PTSD Pre-L-Th (prophylactic) rats were significantly increased compared to that of PTSD vehicle rats (p = .04). Administration of L-Th 24 hours before the initial PTSD event or for 10 days following the last PTSD stress event did not statistically improve mean open arm exploration on the EPM, spatial memory, and learning in the MWM or behavioral despair measured by the FST (p > 0.05). Although the 3-day restraint/tail shock stress model caused stress in the rodents, it did not produce reported PTSD-like anxiety and depression or spatial memory loss. The effect of Pre-L-Th or Post-L-Th treatment, on the neurobehavioral functions could not be effectively evaluated. However, this study provides a foundation for future studies to try different rodent PTSD models to induce PTSD-like neurobehavioral impairments to explore dosage, frequency, as well as the duration of L-Th administration before and/or after the post-traumatic event. The 3-day restraint/tail shock stress model caused stress in the rodents, Pre-L-Theanine treatment preconditioned the PTSD rats to endure stress.

Aim: After a traumatic event, the person can develop post-traumatic stress disorder (PTSD), the purpose of the study is to assess the prevalence of PTSD in adolescents in public middle schools of the prefecture of Salé in Morocco and study anxiety and depression which are the comorbid disorders of the PTSD. The survey was carried out from March to June 2017. Methods: 523 students were selected by the cross-sectional method from fifteen schools that were randomly selected, the age of the students vary between 12 and 17 years. For the survey, standardized questionnaires (the socio-demographic data, the Life Events Checklist, the CPTS-RI (Children's Post Traumatic Stress Reaction Index), the STAIY (State Trait Inventory Anxiety Form Y) and the CDI (Children Depression Inventory) were used which were filled in by the students. Results: The prevalence of PTSD was 70.4% in the students who have PTSD. We found that the prevalence in boys was 46.74%, while in girls it was 53.26%. In addition to that, 81% of students found to be anxious and 51.8% of students have depression. Conclusion: There is a high prevalence of post traumatic stress disorder among adolescents, there are practical implications for the support and care of these adolescents.

Emotional turmoil, disruption, shock, post-traumatic stress disorder (PTSD), doubts in own competences as a professional: these are only few of many feelings and reactions that clinicians might experience when faced with the fact that patients they had treated took their lives. The range of reactions can span from none, which is rare, to severe disorders, and can sometimes result in more precautious treatment of future patients, or even in leaving the field of working with suicidal patients. How clinicians respond depends on many factors, such as the length and intensity of the treatment, the understanding of patients’ suicide, the knowledge and past experiences the clinicians have as well as the response of the patients’ family, and the response and support of the colleagues and the institution in which the treatment took place. Some of these factors can help—while others can hinder—the process of overcoming the traumatic event of patients’ suicide.

This article analyses well-known anti-apartheid activist Winnie Madikizela-Mandela’s prison memoir 491 Days: Prisoner Number 1323/69 (2013) for depictions of suffering. This memoir reveals aspects of politically inflicted trauma, particularly the suffering sustained in prolonged solitary confinement and the resulting psychological sequelae for the prisoner. To move beyond a vague understanding of her traumatic experiences, this article draws on the field of psychiatry, specifically the diagnostic criteria for post-traumatic stress disorder (PTSD) to gain greater insight as this tool may also be regarded as a type of narrative that could aid in the comprehension of traumatic events. References will be made to the three main cluster symptoms of PTSD: involuntary re-experiencing of the traumatic event, avoidance of reminders and an ongoing sense of threat. An interdisciplinary literary-psychological approach will probably lead to a deeper understanding of the mental consequences of political imprisonment, as PTSD was not an acknowledged disorder during Madikizela-Mandela’s detainment.

Post-traumatic stress affects millions of people worldwide. Appraisal training is an intervention that has been used to decrease the negative effects of a traumatic event. In two studies, the acceptance and effects of technology in supporting appraisal was studied. Study 1, a descriptive study, examined the response to and acceptance of a workshop on perspective broadening with technological support among soldiers and firefighters. Results revealed that both groups evaluated the training as useful and feasible, and both favoured the full version of the tool. Study 2 investigated the effect of the support tool among a student sample in comparison to the paper-based training. Participants followed the training individually. Comparisons between the two groups revealed no significant differences on multiple outcome measures. Behaviour observed during the training suggests that shorter sessions might prove more effective. The findings indicate acceptance of the technology supported training but gives no indication that the effects of the training are improved by technological support.

This research study explores the effects of support groups on traumatic stress responses of women experiencing stillbirth. Women ( N = 47) responded to a mixed method questionnaire. Quantitative results utilizing the Impact of Event Scale Revised demonstrate that women who attend support group, when controlling for time, had fewer post traumatic stress symptoms than did the women who did not attend support group. Qualitative results elucidate the role of support groups in managing grief, suggesting that connectivity with other like women may be a useful strategy in reducing problematic psychological outcomes.
