Filter by:The investigators are seeking people who have been exposed to a traumatic event in the past and have symptoms of posttraumatic stress disorder (PTSD) currently. A person with PTSD may feel significant distress when reminded of a traumatic event or feel depressed, anxious or jumpy. As a part of this study, participants will receive brain MRIs and office assessments before and after psychotherapy. The investigators provide the gold-standard psychotherapy for PTSD, "Prolonged Exposure", free of charge; additionally participants are compensated for their time during assessment procedures. This study is exploring the brain circuitry involved in improvement in response to psychotherapy.
The aim of this study was to determine the usefulness of a portable, meditation-based intervention called the Mantram Repetition Program (MRP) for Veterans with military-related posttraumatic stress disorder (PTSD). This study compared the individual delivery of the MRP to individual delivery of Present-Centered Therapy (PCT) at two sites in San Diego, California, and Bedford, Massachusetts.
The purpose of this study is to explore the relationship between attempted and/or completed suicide and reported experience of chronic pain among an adult veteran population. Specific aims include a) examining the experience of chronic pain between patients who have either attempted and/or completed suicide, non-suicide attempt mental health patients, and non-mental health chronic pain patients and b) determining possible differences in reported experiences of chronic pain based on mental and physical diagnoses, age, gender, ethnicity, occupation, and patient's recorded perceptions of depression and/or quality of life. As articulated in the Amendment approved on June 13, 2008, additional areas of interest include histories of neurological disease (e.g. traumatic brain injury) and/or mental health diagnoses. History of both neurologic disease and mental health diagnoses will also be identified by chart review (per approval obtained June 13, 2008). As such this study will also compare differences (e.g., mental health, neurological disease) between veterans who have history of a suicide attempt, completion, or a lifetime history of suicidality and matched control veterans without a history of suicide attempts, completions, or lifetime history of suicide. The relationship between suicidal behavior, attempted/completed suicide, and reported Post Traumatic Stress Disorder (PTSD) symptoms among an adult veteran population is also of interest. Additionally, this data set will be used to complete a validation study regarding the Self-Directed Violence Classification System (SDVCS). Specifically, relevant information in subject chart notes regarding self-directed violence (SDV) will be used to categorize thoughts and behaviors according to the SDVCS.
The purpose of this study is to evaluate, in a randomised control trial (RCT), the effectiveness of group-based, trauma-focused Cognitive Behaviour Therapy (TF-CBT) in reducing psychological distress in former child soldiers and other war-affected children in the Democratic Republic of Congo (DRC).
This is a clinical study for adult subjects with Post Traumatic Stress Disorder.
Despite substantial therapeutic advances, Post-traumatic Stress Disorder (PTSD) remains difficult to treat. One promising new area of research is in post-reactivation pharmacologic intervention, which is based upon the concept of blockade of memory reconsolidation. Recent animal research suggests that reactivation (retrieval) of a stored memory can return it to a labile (alterable) state from which it must be restabilized in order to persist. This process is called "reconsolidation," and various drugs have been found to block it in animals. This blockade may lead to a weakening of the original memory trace. The aim of this study is to pilot the effect of mifepristone on physiologic responding during traumatic imagery. Although mifepristone is widely and safely used to cause a medical abortion, it is also a powerful stress hormone receptor blocker. These stress hormones, called glucocorticoids, may enhance memory (re)consolidation. Indeed, a recent study in animals reported that mifepristone blocked reconsolidation of context-conditioned fear in rats. Reconsolidation blockade is a two-stage process. First, the memory must be destabilized by recalling it. Second, reconsolidation of the memory must be blocked by a drug. Memory traces formed under stressful conditions may resist destabilization and thus are inaccessible to reconsolidation blockers. However, when a reconsolidation blocker was paired with d-cycloserine (DCS) in animals that had been trained under stressful conditions, reconsolidation blockade became successful. These results suggest that DCS promotes the destabilization of resistant memory traces. The traumatic memories of individuals with PTSD may be particularly resistant to destabilization. Therefore, this study will compare mifepristone paired with DCS to placebo controls. The same script-driven traumatic imagery method validated in previous studies of propranolol in this lab will be used. Briefly, subjects with PTSD will describe their traumatic event during a script preparation session, which will reactivate the memory. They will then receive a) mifepristone and DCS or b) placebo. A week later, they will engage in script-driven mental imagery of their traumatic event while physiologic responses (heart rate, sweating, etc) are measured. This is a pilot study so there are no formal hypotheses. The aim is to estimate effect sizes for mifepristone and to compare them with effect sizes for propranolol from this lab's previous work.
Researchers hope to learn whether a flexibly applied cognitive behavioral treatment for Post-Traumatic Stress Disorder (PTSD) is more effective than the psychotherapy usually provided in the clinic (called Treatment as Usual or TAU). Primary Hypothesis: STAIR/NT will be superior to TAU in improving PTSD symptoms at 28, 36 and 48 weeks post-randomization
This study will compare a cognitive-behavioral online self-management intervention designed for primary care treatment of war-related PTSD to a control intervention, "optimized usual primary care PTSD treatment". Patients with PTSD will be trained to use the online PTSD treatment website and asked to do so three times per week for six weeks. They will have phone and email access to a nurse trained to assist them in their treatment program. Three scheduled phone check-ins during the six week treatment period will provide ongoing contact with patients during treatment. The investigators will assess PTSD symptoms, depression, anxiety and somatic symptoms, physical health status and occupational functioning on three occasions: before the intervention, at the end of the treatment period, and six weeks after the end of treatment.
Posttraumatic Stress Disorder (PTSD) is a well-documented phenomenon that occurs in cancer survivors. PTSD is known to cause problems with anxiety, depression, and quality of life. Furthermore, there is little treatment available for cancer survivors who suffer from PTSD. Posttraumatic Growth, however, is a lesser known phenomenon that also occurs in cancer survivors. It is a positive psychological phenomenon that occurs in some people who have suffered a traumatic event--the people who are able to note a "greater appreciation for life", a "stronger relationship with their family/friends," or a "new found level of spirituality" are examples of instances of posttraumatic growth. Coping with Lymphoma to Enhance Adjustment and Reduce Stress in Survivors (CLEAR Stress) is a study designed to compare the development of PTSD versus the development of Posttraumatic Growth in lymphoma patients at any stage of the cancer experience, regardless of treatment. The hypothesis is that posttraumatic growth, if it is significant, can reduce the impact of PTSD symptoms in the survivor.
The purpose of the study is to learn how differences in learning under mildly-stressful circumstances may be changed by taking oxytocin. Oxytocin is a hormone made naturally in the body. The investigators will also examine the impact of any anxiety, depression, and stress related symptoms on learning processes.
