Filter by:This observational study follows subjects who have been exposed to a traumatic event and are at risk of developing PTSD symptoms. Participants are recruited within six hours of a traumatic event, and, starting from the recruitment session, are then examined on six set points of time within a period of thirteen months. The examinations include both biological studies of cortisol in hair, blood and saliva, and psychological examinations and questionaires that assess the development and severity of PTSD symptoms. The novel method of sampling hair cortisol allows investigators to retroactively estimate the mean levels of blood cortisol during the tree months prior to the sampling. The study aims at further illuminating the correlation between cortisol levels both prior and following a traumatic event, and the development and severity of PTSD symptoms
Sunnybrook Health Sciences Centre is Canada's largest trauma centre, treating 1,100 patients annually. A traumatic experience can lead to post-traumatic stress disorder, which increases hospital stays, emergency visits and disability. Despite developing leadership to manage a "Code Orange" mass trauma, Sunnybrook lacks guidelines in the psychological management of patients who have experienced trauma. The department of psychiatry currently holds a Traumatic Brain Injury clinic and PTSD services for youth but lacks both immediate intervention, prevention and adult services. This research will enable us to gain best evidence expertise to develop guidelines as well as a sustainable PTSD treatment program, with clear outcomes to assess effectiveness, psychiatric morbidity, use of healthcare, disability and substance abuse. The five world-expert-consensus intervention resilience based principles will be operationalized in guidelines for the management of trauma patients, their caregivers and in routine nursing and trauma team care from the Emergency to the ward, and discharge, through to outpatient care. It is hypothesized that this will improve the psychological recovery of patients at risk of developing PTSD after a traumatic injury. In addition, early screening and intervention for increased risk of PTSD will be implemented one month after the trauma. It is hypothesized that such trauma informed psychological management, early screening and expert treatment using prolonged exposure will reduce hospital stays, functional disability, as well as longer-term psychiatric morbidity, including substance abuse.
The purpose of this study is to examine the efficacy of exercise + therapy to therapy alone to determine if they can improve the effects of prolonged exposure therapy (PE) in reducing symptoms of anxiety associated with Post-traumatic Stress Disorder (PTSD). In addition the two strategies (i.e., exercise + therapy and therapy alone condition) will be compared in terms of levels of brain-derived neurotrophic factor (BDNF). BDNF is a protein that helps to support the survival of existing neurons and stimulate the growth of new neurons and synapses. BDNF is important to learning and memory in general and therefore may be associated with the learning and memory as it relates to PE and corresponding symptoms PTSD improvement.
The main purpose of this study is to determine whether functional magnetic resonance imaging (fMRI), can distinguish between service members with and without traumatic brain injury (TBI), as well as those with posttraumatic stress disorder (PTSD) who receive either virtual reality exposure therapy (VRET) or PTSD treatment other than exposure therapy. The investigators and other investigators have previously identified changes in function in multiple regions of the brain in combat veterans with PTSD, and the investigators have also seen that structural changes in the white matter associated with combat TBI are also linked with changes in function, and in turn with PTSD symptoms. However, the investigators need to confirm these findings in larger numbers, and also need to discern whether fMRI can distinguish if there is something significantly different about those who have PTSD after TBI vs. those in whom it does not follow a TBI. Finally, the investigators have previously demonstrated that exposure therapy ameliorates the functional changes in the brain induced by PTSD, but the investigators do not know if similar changes occur with other forms of therapy, so the investigators seek to compare the two directly. It is our expectation that the findings will better inform the choice of therapy for service members with combat-related PTSD, with or without TBI.
Research shows that people with PTSD are more likely to smoke than people without PTSD. It also shows that people with PTSD have more difficulty at attempts to quit smoking. This study is part of a program aimed at finding out how best to help smokers quit who also have PTSD. One option is to give patients standard smoking cessation treatment including nicotine replacement and cognitive behavioral therapy. Another option is to give patients the standard smoking cessation treatment in addition to treatment for their PTSD symptoms (called prolonged exposure). However, it is not known which method works better. In order to answer this question, patients will be assigned by chance to one of two groups. One group will be given standard smoking cessation treatment to help quit smoking. A second group will be given the standard smoking cessation intervention to help quit smoking in addition to a form of psychotherapy called Prolonged Exposure to reduce symptoms of PTSD. The patients will be randomly assigned (by chance) to one of these groups. If the patient is assigned to the smoking cessation only condition and the patient still has PTSD symptoms after the last study visit (week 30) the patient will be offered treatment for your PTSD symptoms (Prolonged Exposure) at no cost. The patient's participation will help the investigators determine if treating PTSD symptoms enhances the ability of standard smoking cessation to help people quit smoking.
To evaluate the efficacy of brexpiprazole as adjunctive treatment to paroxetine or sertraline on PTSD symptoms.
The purpose of this study is to implement an evidence-based Referral Management System that will address patient and system-level barriers to the uptake of evidence-based psychotherapy for PTSD by Veterans Affairs primary care patients.
This randomized pilot clinical trial studies the effects of meditation-based breathing training on patients' control of their breathing patterns and breathing-related movement, as well as on their psychological distress and treatment experience during radiation therapy. Meditation-based breathing training may decrease breathing-related movement and the amount of stress by improving breathing patterns in patients with abdominal or lung cancer undergoing radiation therapy.
VA Cooperative Study CSP #591 is designed to compare the effectiveness of two types of psychotherapy, Prolonged Exposure (PE) and Cognitive Processing Therapy (CPT), for treating posttraumatic stress disorder (PTSD) in male and female Veterans. Despite solid evidence that both treatments are effective in Veterans and non-Veterans, there is a lack of evidence about the effectiveness of these treatments compared with one another. The sample will include 900 male and female Veterans with PTSD due to any traumatic military event. Veterans who are eligible and agree to participate in the study will be randomly assigned (by chance) to receive Prolonged Exposure or Cognitive Processing Therapy. The standard "dose" of treatment is 12 weekly sessions but Veterans who improve more rapidly may finish in fewer sessions and Veterans who improve more slowly may have additional sessions. The primary outcome is improvement in PTSD symptoms after treatment. The outcome will be measured at regular follow-up visits that will occur at the middle and at the end of treatment and then 3 and 6 months later. The investigators will measure other outcomes, including additional mental health problems, functioning, quality of life, and use of treatments for mental and physical problems. The investigators also will measure Veterans' treatment preference and examine whether Veterans who get the treatment they prefer do better than Veterans who get the less-preferred treatment. As a large multi-site trial with men and women, CSP #591 is designed to provide conclusive information about whether one treatment is better than the other, overall and for different types of patients-for example, men vs. women, combat Veterans vs. Veterans who experienced military sexual trauma, and older vs. younger Veterans. Regardless of the outcome, patients will have more information to help them make an informed decisions about which treatment to choose and VA will have stronger evidence to help make care Veteran-centered.
One of the most pressing concerns within the VA currently is the provision of interventions that address the cognitive as well as emotional problems faced by Veterans with concurrent mild TBI and PTSD. One purpose of this study is to learn more about how PTSD and mild brain injury influences how people think, act, and feel. This may include how people pay attention, keep information in memory, organize plans for achieving important goals, and manage stress. Another purpose of this research is to learn more about the effects of cognitive training on the thinking, behavior, and emotions of individuals with PTSD and mild brain injury - both in the short- and long-term. With this research, the investigators hope to better understand and treat cognitive and emotional difficulties that can occur due to PTSD and mild brain injury.
