This year, more than 1311 physicians of all specialties responded to the survey . . . 287 of the respondents are psychiatrists. The charts you see show how those 287 responded to just a few of the survey questions. Read More

OBJECTIVE: To study heart rate variability (HRV) and cortisol levels as biomarkers of stress and autonomic function in patients with functional movement disorders (FMD).
BACKGROUND: FMD patients present with abnormal movements without known neurological cause, often presumed to have a "psychogenic" etiology. The goal of this study was to measure biomarkers of stress in FMD patients. Cortisol is the final effector hormone of the hypothalamic pituitary adrenal (HPA) axis and its secre
OBJECTIVE: To determine long-term post-traumaticstressdisorder (PTSD) in this population.
BACKGROUND: Guillain-Barré syndrome (GBS) is an acute inflammatory disease of the peripheral nervous system. Its severity depends on respiratory muscles and autonomic nervous system dysfunction. Nearly 30% of patients require mechanical ventilation (MV) and patients with more severe forms may require MV for several months. PTSD is a potentially serious psychiatric disorder that could b
OBJECTIVE: Design of a novel screening tool for TBI in the military.
BACKGROUND: TBI is the "signature injury" of the wars in Iraq and Afghanistan. 15-23% of service members deployed to these locations have experienced a TBI. There is a need for validated instruments tailored to accurately screen for TBI in this population.
DESIGN/METHODS: 300 service members or veterans underwent a novel screen and comprehensive diagnostic assessment to identify the occurrence of TBI,
OBJECTIVE: We tested the hypothesis that severity of traumatic brain injury (TBI) is associated with mild cognitive impairment (MCI) controlling for post-traumaticstressdisorder (PTSD).
BACKGROUND: TBI is the signature injury of the wars in Afghanistan and Iraq, with a majority being mild TBI (mTBI). TBI may cause MCI and is associated with increased risk of neurodegeneration, highlighting a need for accurate early diagnosis and appropriate follow-up of TBI patients. MCI is a usef
Anaesthetic awareness is a recognized complication of general anaesthesia (GA) and is associated with post-traumaticstressdisorder (PTSD). Although complete amnesia for intraprocedural events during sedation and regional anaesthesia (RA) may occur, explicit recall is expected by anaesthesia providers. Consequently, the possibility that there could be psychological consequences associated with unexpected explicit recall of events during sedation and RA has not been investigat
Emotional learning is extremely important for the survival of an individual. However, once acquired, emotional associations are not always expressed. The regulation of emotional responses under different environmental conditions is essential for mental health. Indeed, pathologic feelings of fear and anxiety are defining features of many serious psychiatric illness, including post-traumaticstressdisorder (PTSD) and specific phobias. The simplest form of regulation of emotional responses is extinction, in which the conditioned response to a stimulus decreases when reinforcement (stimulus) is omitted. In addition to modulating basal anxiety states, recent studies suggest an important role for the endocannabinoid (eCB) and glucocorticoid systems in the modulation of emotional states and extinction of aversive memories in animals. The purpose of this review is to briefly outline the animal models of fear extinction and to describe how these have been used to examine the potential of
Pathophysiological regulation of the stress response involves a number of complex interactions at the organismal, cellular and molecular levels. A salient feature of the stress response is the activation of the hypothalamic-pituitary-adrenal axis. Molecular studies of this phenomenon have found a number of genes which are differentially expressed in stressed individuals and control subjects. The transcription factor NF-kappaB controls many of these genes, which is evidence of the key role it plays in the cellular stress response. Stress upregulates a number of genes such as the transcription factor genes that control cell growth, chromatin structure, cell cycle activation and enzymes involved in the biosynthesis of nucleic acids and proteins. The genes that are down-regulated in stress are cell cycle inhibitors, apoptosis related genes, antiproliferative cytokines and Apo J, the NF-kappaB inhibitor. Post-traumaticstressdisorder (PTSD) is an anxiety disorder which develops as a
Eye movement desensitisation and reprocessing (EMDR) is a powerful psychotherapy with well-researched benefits for adults and children who are experiencing post-traumaticstress and post-traumaticstressdisorder. There is a wealth of research and practice-based evidence demonstrating the effectiveness of EMDR in many differing clinical presentations but the true potential of this extraordinarily beneficial therapeutic approach has not been fully embraced by the mental health nursing profession.
Reserve and National Guard forces have been mobilized to an unprecedented degree in recent overseas conflicts. There is concern that rates of psychological problems may continue to rise for many years after deployment. The authors conducted a cohort study of 552 United Kingdom Reservists who deployed to Iraq in 2003 and 391 nondeployed Reservists. Measures of mental health and social functioning were collected a mean of 16 months and 4.8 years after return from possible deployment. At the first follow-up, deployment was associated with increased common mental disorder, post-traumaticstressdisorder (PTSD), and poor general health. By the second follow-up, those who had deployed were no longer at increased risk for common mental disorder or poor general health and had good levels of social functioning. However, those who deployed continued to have over twice the odds of PTSD (odds ratio = 2.42, 95% confidence interval: 1.04, 5.62) and were more likely to report actual or serious
Information processing accounts of post-traumaticstressdisorder (PTSD) state that intrusive memories emerge due to a lack of integration between perceptual and contextual trauma representations in autobiographical memory. This hypothesis was tested experimentally using an analogue trauma paradigm in which participants viewed an aversive film designed to elicit involuntary recollections.|Participants viewed scenes from the film either paired with contextual information or with the contextual information omitted. After viewing the film participants were asked to record for one week any involuntary intrusions for the film using a provided intrusions diary.|The results revealed a significant increase in analogue intrusions for the film when viewed with contextual information in comparison to when the film was viewed with the contextual information omitted. In contrast there was no effect of contextual information on valence ratings or voluntary memory for the film, or on the reported
The core symptoms of PTSD include re-experiencing of the traumatic event with intrusive thoughts and dreams, avoidance of reminders of the event, emotional numbing, hypervigilance, excessive startle response, and chronic ... 2. Yehuda R. Post-traumatic
