Filter by:The purpose of this study is to determine whether the drug prazosin is effective for the treatment of alcohol dependency and symptoms of Posttraumatic Stress Disorder (PTSD).
Identifying neural mechanisms of posttraumatic stress disorder (PTSD) treatment could help elucidate reasons for variable treatment response and identify novel treatment targets. Exposure-based therapies have been associated with decreased amygdala and increased cingulate cortex response during emotional processing. The current study examined whether cognitive therapy for PTSD in women reduces activation in insula and amygdala and enhances activation in prefrontal regions during emotional anticipation and pre-treatment prefrontal activation predicts treatment response.
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.
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.
This study will consist of a single session of MDMA-assisted therapy with a full dose of MDMA for people who took part in a study of MDMA-assisted therapy in people with posttraumatic stress disorder (PTSD) whose PTSD symptoms returned to higher levels at least a year after the first MDMA sessions. The single session will be performed by the same pair of therapists who performed the sessions in the first study. People will have a preparatory session, the MDMA-assisted session and three non-drug sessions afterward. Their PTSD symptoms and symptoms of depression will be measured at the start of this study and two and 12 months after the session.
The purpose of the proposed study is to determine if pairing reactivation of a traumatic memory with a single administration of Rapamycin (e.g., Sirolimus) in men with combat-related Posttraumatic Stress Disorder leads to a reduction of the emotional strength of that particular traumatic memory. The following hypotheses will be tested: 1. Traumatic memory reactivation paired with a single dose of Rapamycin will decrease objective measures of stress and self-report of stress during replay of the traumatic memory, relative to, subjects receiving placebo. 2. Pairing administration of Rapamycin with traumatic memory reactivation will decrease symptoms of Posttraumatic Stress Disorder one month and three months later, relative to patients receiving placebo.
The purpose of this study is to evaluate whether a brief intervention in video format, that includes education about reactions to assault and modeling of adaptive coping strategies, designed to reduce post assault drug use or abuse and PTSD and shown to recent victims of sexual assault at the time of receipt of post assault medical care is associated with better post-assault outcomes as compared to a comparable length video that includes pleasant imagery and relaxation instruction or standard care.
Up to half of all military service members with combat-related traumatic brain injury (TBI) also suffer from Posttraumatic Stress Disorder (PTSD). TBI and PTSD are each associated with cognitive problems in what are called 'executive functions' such as planning actions, inhibiting behavior, monitoring one's own thoughts and feelings, and solving problems day-to-day. These types of impairments occur more often among veterans with both TBI and PTSD than among those with only one of these conditions. The combination of TBI and PTSD in veterans has also been linked to problems with anger and violence, which are common complaints of veterans seeking mental health services post-deployment and have been shown to predict poor treatment outcomes in Iraq and Afghanistan veterans. Although the relationship between combined TBI/PTSD diagnoses and post-deployment adjustment problems has been demonstrated, there has been little research into clinical interventions designed to reduce the severity of cognitive and affective symptoms in veterans with both TBI and PTSD. Therefore, the investigators propose a randomized clinical trial involving a cognitive rehabilitation intervention that targets improved executive functioning, with the participation of N=100 veterans diagnosed with both TBI and PTSD (n=50 in experimental group and n=50 comparison). As part of the study, all participants will receive an iPod touch. Participants will be placed into one of the two study groups randomly. Based on which group participants are placed in, they will receive one of two different sets of iPod touch apps and programs that address and aim to improve different facets of cognitive functioning. Regardless of which group, Veterans will be instructed to daily practice iPod touch applications on cognitive functioning. Also, family members will be trained as "mentors" to reinforce use of the applications in everyday living environments. Trained facilitators will also travel to participants' homes to meet with veterans and family to observe behaviors in the home environment, arrive at strategies for applying new skills in their situations, troubleshoot any iPod technical problems, and review family mentoring processes. The investigators will measure clinical outcomes using a comprehensive array of functional and structural methods at baseline and six months. The investigators hypothesize improved executive function among those in the experimental group as well as reduced irritability/impulsivity and improved social/occupational functioning. The investigators further hypothesize that, as a group, veterans participating in the cognitive rehabilitation program will show significant changes in neural activity associated with executive functions when comparing pre- and post-treatment EEG and fMRI responses. Better understanding of the neural circuitry and neurocognitive function underlying executive function and associated affective control deficits in veterans with both TBI and PTSD, and how they relate to treatment outcome, will allow us to better identify therapeutic targets for cognitive rehabilitation. The current proposal aims to explore the relationship between brain function and connectivity in selective pathways/circuits, neuropsychological functioning, and cognitive rehabilitation response in veterans with both TBI and PTSD. This study of the neurobiology and neuropsychology associated with intervention efficacy will allow us to identify veterans with both TBI and PTSD who are predisposed to positive treatment outcomes. To our knowledge, this will be the first attempt to integrate neurobiological and neurocognitive techniques with information about the efficacy of a theoretically and empirically driven cognitive rehabilitation intervention in veterans with combined TBI/PTSD diagnoses. This research may suggest additional avenues for assessment of clinical intervention efficacy and the identification of therapeutic targets (e.g. alteration of function in fronto-limbic circuits) relevant to the military population. Given links between TBI/PTSD, executive dysfunction, and anger, impulsivity, and aggression, efforts to rehabilitate cognitive function will be particularly important to ensure that current and future veterans adjust successfully when they return home to their families, workplaces, and communities.
The purpose of this study is to test if provision of an effective psychotherapy for Post-traumatic Stress Disorder (PTSD), prolonged exposure, can be tolerated in alcohol dependent patients with PTSD and if it is associated with better treatment outcomes compared to an active control condition.
