Filter by:Traumatic experiences can have a profound negative effect on the lives and well-being of both the people who experience them and their loved ones. For those who experience post-traumatic stress disorder (PTSD), their interpersonal difficulties and social support further impact the success of treatment such that interpersonal difficulties are associated with mistrust and predict poor treatment outcome. In this proposal, the investigators use functional neuroimaging to understand the neurobiology of trust and mistrust in people with PTSD and to learn more about how successful treatment can improve trust and social functioning.
Converging lines of evidence have implicated the amygdala in the pathophysiology of posttraumatic stress disorder. The primary purpose of our study is to assess the effect of propanolol, a beta adrenergic antagonism, on amygdala activation during a symptom provocation state in traumatized subjects with and without posttraumatic stress disorder.
To investigate the prevalence of posttraumatic stress disorder (PTSD) in patients that underwent surgery for primary rhegmatogenous retinal detachment (RRD) and to determine variables associated with the disorder. Design: Consecutive prospective observational study.
Background: Current military involvement in Afghanistan (Operation Enduring Freedom - OEF) and Iraq (Operation Iraqi Freedom - OIF) has created unforeseen burdens on the mental health and well-being of US service women and men. Although OEF/OIF service members and veterans are at high risk of developing sub-threshold combat stress and depressive symptoms or full disorders in the post-deployment period, only a small fraction ever receive care. The VETS PREVAIL Intervention, which combines Cognitive-Behavioral-Therapy-based (CBT-based) coping skills training with peer-to-peer support and counseling, was specifically designed to offer the returning OEF/OIF service member or veteran an accessible and confidential first step to care. Evaluation Study: RISE Consulting, lead by Dr. Benjamin W. Van Voorhees, MD, MPH, was contracted to supervise a pilot study of potential benefit, feasibility and safety of the VETS PREVAIL Intervention. The study would consist of a single group pre/post comparison study of N=50 recent OEF/OIF veterans in the frame work of a phase 1 clinical trial (phase 1). Feasibility (adherence and satisfaction), evidence of clinical benefit would be evaluated through changes in the following clinical self-report measures: i) symptoms of depressed mood (Center for Epidemiologic Studies Depression Scale, CES-D), ii) post traumatic stress disorder (Post Traumatic Stress Disorder Checklist-Military, PCL-M), and iii) functional status (Short Form 12, SF-12), as well as changes in key attitudes toward mental health care seeking (intent to seek treatment, mental health self-efficacy and stigma).
Post traumatic Stress disorder (PTSD) is a common condition for persons who have served in the Armed services during combat or deployment. Treatments include medications, cognitive behavioral therapy, and other social support mechanisms. Our aim in this project is to critically evaluate the effects of a novel music therapy intervention on the symptoms of PTSD. Estimates developed by the Global Burden of Disease Study reveal that mental illness accounts for over 15% of the burden of disease on health and productivity in established market economies--more than the disease burden caused by all cancers combined.[1] Perhaps no industry has had the burden of mental disorders affect its labor force as severely and pervasively as the Armed Forces. Post-Traumatic Stress Disorder (PTSD) is a common sequelae of severe emotional trauma that is often associated with combat exposure. The condition has been well documented in returning soldiers and is characterized by recurrent and distressing thoughts and feelings related to the trauma, persistent avoidance of reminders of the trauma, and increased arousal that disturbs sleep, concentration, and the ability to modulate anger. Persons suffering from PTSD often have difficulty relating to others, leading to loneliness and isolation, which further intensifies their psychiatric symptoms. Current treatment options for PTSD include psychotherapy, medication management, or a combination of those. Although these treatments have been shown to be effective, returning soldiers are often hesitant to seek and adhere to mental health therapies. PTSD-related avoidance, including difficulty trusting, may serve as a barrier to seeking or completing treatments. Furthermore, some PTSD medications have unacceptable side-effects in some individuals. The need is great, therefore, to identify and promote safe, effective strategies for self-management of PTSD among Veterans.
This preliminary study will examine the differential effects of rTMS on the recall of extinction of conditioned fear in patients suffering from PTSD (post-traumatic stress disorder ) compared with subjects without PTSD but with high risk of relapse.
PTSD is a pervasive and frequent disorder. Early psychological treatment - but not pharmacology - effectively prevent PTSD. Current pharmacological studies did not include treatment given immediately after trauma exposure. However, a recent study of opiates suggests that their early administration may reduce the likelihood of developing PTSD - possibly by mitigating early post-traumatic distress (UCR) - within an adequate window of time. Benzodiazepines are often used to reduce anxiety and agitation during stressful situations - including traumatic event. These compounds may increase the likelihood of developing PTSD when administered few days after the traumatic event - but their effect as an immediate intervention has not been studied - despite their frequent and uninformed use at this stage. This work will evaluate the effect of diazepam - a BZ compound - on PTSD symptom trajectory following traumatic event in a randomized controlled design. Following the studies of opiates it is hoped that diazepam, administered within hours of the traumatic event, and before the first night sleep (a memory consolidating condition) will reduce the likelihood of developing PTSD. However, an adverse effect cannot be excluded, and thus the investigators posit a bidirectional hypothesis. The importance of this work is that it will provide the necessary evidence to sanction a frequently practiced use of benzodiazepines.
The investigators hypothesize that carvedilol, at less then therapeutic doses for cardiac effect, will reduce symptoms of Post Traumatic Stress Disorder.
Stress-related disorders are among the most prevalent and expensive medical consequences of participation in military operations. Omega-3 fatty acids EPA/DHA derived from fish oil are known to benefit both neuronal development in the young, and cognition and mood in various populations. It is possible that soldiers receiving Omega-3 EPA/DHA will exhibit significantly higher cognitive performance, better affect/mood state, and less combat stress symptomatology compared to the placebo after 12 weeks of supplementation. A goal would be to reduce the prevalence of combat stress injuries in military personnel.
This study is designed to provide information on whether therapy ("talk therapy") combined with the drug MDMA is safe and helpful for subjects with posttraumatic stress disorder (PTSD). The study will compare the effects of a low, a medium and a full dose of MDMA on symptoms of PTSD in 24 veterans, firefighters or police officers. MDMA dose will be assigned at random, and the investigators and the subject will not know the dose given. The researchers will also investigate depression symptoms. The researchers believe that the full dose of MDMA will produce a greater reduction in PTSD symptoms than the two lower doses.
