The amygdala is a key brain area regulating responses to stress and emotional stimuli, so improving our understanding of how it is regulated could offer novel strategies for treating disturbances in emotion regulation. As we review here, a growing body of evidence indicates that the gut microbiota may contribute to a range of amygdala-dependent brain functions from pain sensitivity to social behavior, emotion regulation, and therefore, psychiatric health. In addition, it appears that the microbiota is necessary for normal development of the amygdala at both the structural and functional levels...

REVIEW
David A Brent, Jeffrey Max
PURPOSE OF REVIEW: The purpose of this study was to review the frequency, risk factors, phenomenology, and course of prolonged recovery from concussion and of psychiatric sequelae in pediatric populations. RECENT FINDINGS: Youth with prolonged recovery from concussions have higher initial symptoms, a history of multiple and/or recent concussions, and a tendency to somatization. Depression, post-traumatic stress disorder, behavioral disorders, and perhaps, suicidal behavior disorder are more common as both short- and longer-term sequelae of concussions...

BACKGROUND: The role of gender in posttraumatic cognitions has increasingly been approached. The current study comparatively evaluates posttraumatic cognitions in men and women exposed to specific nonsexual trauma (motor vehicle accidents, work - related accidents, burns). METHODS: Posttraumatic cognitions and posttraumatic stress symptoms were comparatively assessed in 53 men and 37 women treated in 3 Romanian primary care units after specific accidental trauma...

Introduction Quality of life (QOL) is significantly impaired among individuals with post-traumatic stress disorder (PTSD); however, few treatment outcome studies examine QOL following treatment. Furthermore, the use of videoconferencing to deliver evidence-based treatments for PTSD is increasing dramatically. Although videoconferencing has demonstrated non-inferiority to in-person treatment modalities for improving PTSD symptom severity, no studies to date have directly compared QOL outcomes of an evidence-based intervention delivered via videoconferencing to one delivered in-person...

The international guideline for complex posttraumatic stress disorder (ptsd) from the International Society for Traumatic Stress Studies (istss) recommends treatment in phases, starting with stabilisation treatment. Different forms of stabilisation training have been developed the past few years, one being short-term group stabilisation training.<br/> AIM: To map out the effects of the short-term group training.<br/> METHOD: The research implemented a pre-post design. The training consisted of five group sessions...

An alternative to objectifying approaches to understanding Post-traumatic Stress Disorder (PTSD) grounded in hermeneutic phenomenology is presented. Nurses who provided care for soldiers injured in the Iraq and Afghanistan wars, and sixty-seven wounded male servicemen in the rehabilitation phase of their recovery were interviewed. PTSD is the one major psychiatric diagnosis where social causation is established, yet PTSD is predominantly viewed in terms of the usual neuro-physiological causal models with traumatic social events viewed as pathogens with dose related effects...

Post-traumatic stress disorder (PTSD) is predominant amongst individuals addicted to opioids and obscures the course of illness and the treatment outcome. We report the case of a patient with major depressive disorder and opioid dependence, who experienced post-traumatic stress disorder symptoms during a recent visit to the inpatient unit. The similarity of symptoms between post-traumatic stress disorder and opioid dependence is so high that, sometimes, it is a challenge to differentiate between these conditions...

BACKGROUND: Post-intensive care syndrome includes the multiple consequences of an intensive care unit (ICU) stay for patients and families. It has become a new challenge for intensivists. Prevention programs have been disappointing, except for ICU diaries, which report the patient's story in the ICU. However, the effectiveness of ICU diaries for patients and families is still controversial, as the interpretation of the results of previous studies was open to criticism hampering an expanded use of the diary...

BACKGROUND: To determine the patterns and predictors of treatment response trajectories for veterans with post-traumatic stress disorder (PTSD). METHODS: Conditional latent growth mixture modelling was used to identify classes and predictors of class membership. In total, 2686 veterans treated for PTSD between 2002 and 2015 across 14 hospitals in Australia completed the PTSD Checklist at intake, discharge, and 3 and 9 months follow-up. Predictor variables included co-morbid mental health problems, relationship functioning, employment and compensation status...

While research has demonstrated an association between trauma and mental health, this study examined the association between trauma experienced premigration, during migration, and postmigration, and current mental health status among Latino youth aged 12-17 years old living in the US for < 3 years. Participants reported traumatic events experienced in their home country, during migration, and after settling in the US. Regression models examined trauma experienced at each stage of the migration process predicting current levels of depression, anxiety, and post-traumatic stress disorder...

The current study screened for post-traumatic stress disorder (PTSD) and self-harming behaviours, often related to borderline personality disorder (BPD), among individuals in a job centre considered unemployable primarily for psychological reasons. Participants (N = 112) filled in questionnaires on PTSD symptoms (n = 62) and self-harming behaviours (n = 59) as part of participating in team-meetings providing the individuals with a return-to-work plan. Differences in demographic variables between individuals with and without valid protocols were small to moderate...

In this study, we compared 10 ethnic groups for associations between psychiatric disorders and physical self-rated health (SRH) in the United States. Data came from the Collaborative Psychiatric Epidemiology Surveys (CPES), 2001-2003. The study included 7587 non-Latino White, 4746 African American, 1442 Mexican, 1106 other Hispanic, 656 other Asian, 600 Chinese, 577 Cuban, 520 Vietnamese, 508 Filipino, and 495 Puerto Rican individuals. The Composite International Diagnostic Interview (CIDI) was used to measure psychiatric disorders, including major depressive disorder (MDD), general anxiety disorder (GAD), social phobia, panic disorder, post-traumatic stress disorder (PTSD), alcohol abuse, and binge eating disorders...

Controllability is an important factor in determining stress outcomes. Uncontrollable stress is associated with the development of psychopathology such as post-traumatic stress disorder, whereas controllable stress is associated with adaptive stress responses and positive outcomes. In this study, we investigated how controllability affects poststress neurobiology by assessing transcriptional levels of activity-dependent genes in medial prefrontal cortex (mPFC) and amygdala, regions important in mediating stress outcomes...

OBJECTIVES: The innate alarm system (IAS) models the neurocircuitry involved in threat processing in posttraumatic stress disorder (PTSD). Here, we investigate a primary subcortical structure of the IAS model, the superior colliculus (SC), where the SC is thought to contribute to the mechanisms underlying threat-detection in PTSD. Critically, the functional connectivity between the SC and other nodes of the IAS remains unexplored. EXPERIMENTAL DESIGN: We conducted a resting-state fMRI study to investigate the functional architecture of the IAS, focusing on connectivity of the SC in PTSD (n = 67), its dissociative subtype (n = 41), and healthy controls (n = 50) using region-of-interest seed-based analysis...

Symptoms of posttraumatic stress disorder (PTSD) and major depressive disorder are the most frequently co-occurring problems following potentially traumatic events. It is unclear whether these comorbidities represent two correlated but distinct disorders or a common post-event response. We sought to inform this question by examining the distinctiveness of PTSD and depression symptoms at four cross-sectional time points, using data from a parent prospective longitudinal study of 858 Marines evaluated before deployment and approximately 1, 5, and 8 months after returning from the Afghanistan war...

There is a growing body of research on yoga as a therapeutic intervention for psychological symptoms of post-traumatic stress disorder (PTSD) accompanied by speculations on underlying physiologic mechanisms. The purpose of this systematic review is to identify, qualitatively evaluate, and synthesize studies of yoga as an intervention for PTSD that measured physiologic outcomes in order to gain insights into potential mechanisms. The focus is on studies evaluating yoga as a therapeutic intervention for PTSD rather than for trauma exposure, PTSD prevention, or subclinical PTSD...

BACKGROUND: In patients with post-traumatic stress disorder (PTSD) two open pilot studies about the effects of 35% carbon dioxide (CO2) exist. One shows an augmented panicogenic and anxiogenic response (Muhtz et al., 2011), the other does not (Talesnik et al. 2007). We further characterized the CO2 reactivity in PTSD using for the first time placebo-controlled and double-blind conditions. METHODS: In 20 patients with PTSD we assessed panic, anxiety, dissociative and PTSD symptoms after a single vital capacity inhalation of 35% CO2 compared to a placebo gas condition in a within-participant cross-over, placebo-controlled, double-blind and randomized design...

AIM: The literature is sparse with respect to the impact of elevated maternal psychological distress in the neonatal intensive care unit (NICU) on later neurodevelopmental outcome in VLBW infants. The objective of this study is to examine the impact of elevated maternal distress, defined as elevated depression, anxiety and perinatal-specific post-traumatic stress, during the NICU hospitalization on VLBW infant ND outcome at 20months corrected age (CA). METHODS: This was a prospective study of 69 mothers and their VLBW infants recruited in 2011-2012...
