Filter by:Sleep impairment is the most often reported of the 17 PTSD symptoms and is considered one of the most refractory to treatment. This study proposes the use of sleep-directed hypnotherapy to address sleep issues as a complementary element to empirically supported Cognitive Processing Therapy (CPT) in treating PTSD in sexual and physical assault survivors. Specifically the study aims to: 1) compare the results of sleep-directed hypnosis plus CPT with CPT only, 2) to assess the relationship between sleep and PTSD symptoms, 3) to examine relationships between sleep improvement, PTSD symptom improvement, and the therapeutic elements (hypnosis, exposure, cognitive therapy) to determine mechanisms of action in the intervention, 4) to assess the relationship between sleep and physical reactivity to trauma-related cues and to other stimuli.
Many active duty military, national guard, and reserves personnel who served in the recent conflicts in Afghanistan and Iraq were exposed to blasts and other mechanisms of traumatic brain injury (TBI).1,2 Although physical trauma is not unexpected during war fighting, survival after head injury, particularly blast-related, has become a common occurrence only in recent decades. As such, the associated cerebral damage is less well studied and understood, particularly over the long term. The Brain Injury Outcomes (BIO) is a longitudinal study with the short-term objective of better characterizing multi-modal outcomes in individuals who have sustained a brain injury using a systems medicine approach. Long-term aims include monitoring participants for signs of emerging symptoms or age-related vulnerabilities. Identification of abnormality profiles for multiple severity levels of brain injury (from any source, including blast and non-blast) reflects a second long-range goal. Third, the investigators will examine and compare physiology between Veterans who have sustained a Mild Traumatic Brain Injury (mTBI) with and without persisting symptoms and various co-morbidities including posttraumatic stress disorder (PTSD) and depression. A control group of Veterans who have not sustained a TBI will also be recruited for comparison. Fourth, the investigators intend to facilitate the clinical use of advanced methodologies, such as brain imaging measures, with the brain injured (and other populations). Finally, the investigators will assess methods of analysis, separately and in combination through integration, for multi-modal data in search of diagnostic profiles. Increased knowledge of injury patterns and the trajectory associated with brain injury could contribute to better methods of diagnosis, monitoring and, perhaps, treatment. This investigation has spawned several sub-studies, one of which was the Validation of Brief Objective Neurobehavioral Detectors (BOND) of Mild TBI, which continues. The investigators have collaborated with Harvard/Boston Children's Hospital in the Angiogenic Signaling Signatures Identified in Stress and Trauma (ASSIST) sub-study. Oak Ridge National Laboratory (ORNL) will assist in integrating BIO Study multi-modal data. Investigators at Johns Hopkins School of Medicine collaborate with neuroimaging sequences and methods.
To find out if Cranial Electrotherapy Stimulation is a useful treatment for people who have been burned and have Post Traumatic Stress Disorder. CES may be helpful in giving relief to some or all of those symptoms.
The purpose of this study is to improve care in the Intensive Care Unit (ICU) by focusing on communication with family members of patients who are too sick to make decisions about their own care while they are in the ICU. The randomized trial will test the efficacy of a communication intervention designed to improve communication between families and clinicians through the use of a facilitator. Outcome evaluation occurs at the level of the individual family with surveys completed by families and clinicians.
The purpose of this study is to perform an evaluation of a trauma-focused short-term intervention (Narrative Exposure Therapy; Schauer, M., Neuner, F. & Elbert, T.) on a variety of clinical outcome measures (PTSD, Depression, Somatic Complaints, Dissociation) in women after sexual exploitation and women trafficking.
This study will evaluate the effectiveness of trauma-focused cognitive behaviour therapy (TF-CBT) versus eye movement desensitization and reprocessing (EMDR) in the treatment of trauma survivors with post-traumatic stress disorder (PTSD). Patients will be randomly assigned to TF-CBT or EMDR. Follow-up assessments will be conducted at 3 and 12 months post-treatment. In addition to comparing the efficacy of the two protocols, an additional focus will lie on identifying predictors for treatment outcome.
The consolidation of learning is enhanced by adrenalin and other stress hormones. This memory enhancing effect is opposed by propranolol. In posttraumatic stress disorder (PTSD), a psychologically traumatic event may overstimulate stress hormones such as adrenalin, which in turn overly strengthen consolidation of the memory of the event, leading to an excessively powerful and persistent memory. Administration of propranolol after a psychologically traumatic event could reduce subsequent PTSD. Unfortunately, there exists a window of opportunity for influencing the consolidation of a traumatic event into long-term memory. In persons who have already developed PTSD, this would have closed months or years earlier. However, recent developments in animal research suggest that reactivation (retrieval) of a consolidated memory can return it to a labile state, from which it must be restabilized in order to persist. This process, which has been termed "reconsolidation," can be reduced in animals by propranolol. In a preliminary study performed by the PI and colleagues in Canada, civilian participants with PTSD described the traumatic event during a script preparation session, which served to reactivate their traumatic memory. They then received either propranolol or placebo. A week later, during script-driven imagery of their traumatic events, physiologic responses were smaller in the participants who had received post-reactivation propranolol compared to placebo, suggesting that the traumatic memory had been weakened by the propranolol. These results suggest that that post-reactivation propranolol recapitulates its effects on consolidation, this time by blocking reconsolidation of the traumatic memory. Several important questions remain unanswered. First, does propranolol also weaken traumatic memories in combat-related PTSD? Second, does this weakening effect only occur when the propranolol is given after combat memory reactivation? If not, this would refute the reconsolidation hypothesis and suggest that propranolol affects non-specific mechanisms. Third, how long does the traumatic memory weakening last? The proposed project will investigate these questions by performing an improved, double-blind, placebo-controlled study in Iraq and Afghanistan veterans with combat-related PTSD. Participants will be randomly assigned to one of two groups: post-reactivation propranolol or non-reactivation propranolol. Participants in the non-reactivation propranolol group will receive propranolol in the absence of traumatic memory reactivation. Participants randomized to the post-reactivation propranolol group will receive matching placebo capsules. Two days later, all participants will return for a script preparation session, at which time they will describe the details of their traumatic event. Participants randomized to the post-reactivation propranolol group will then receive propranolol, whereas participants randomized to the non-reactivation propranolol group will receive placebo. Participants will then return for psychophysiologic script-driven imagery testing one week and six months later. We hypothesize that those who receive propranolol after reactivation of their memories of their traumatic combat event(s) will show significantly smaller psychophysiologic responses during script-driven imagery testing compared to participants who receive propranolol in the absence of combat memory reactivation, supporting the inference that post-reactivation propranolol blocks the reconsolidation of traumatic combat memories.
Developing novel and effective pharmacologic interventions for this post-traumatic stress disorder is important. The investigators propose to replicate findings of an earlier published pilot study using low dose hydrocortisone as a treatment for PTSD. In order to do so in a more meaningful way, the investigators will conduct a larger but similar randomized double-blind placebo-controlled, cross-over design treatment study examining the use of low dose hydrocortisone (or placebo) for 4 weeks in combat veterans suffering from PTSD. The investigators hypothesize that, as described by Aerni et al. (2004), administration of daily hydrocortisone will lead to a reduction in PTSD symptom severity, but particularly for re-experiencing types (e.g., flashbacks, nightmares)of symptoms. The investigators also hope to examine potential predictors and moderators of treatment response based on subjects' clinical characteristics, as well as serum cortisol and ACTH levels.
The investigators are testing novel treatments for combat PTSD: bright light exposure and negation ion exposure.
The purpose of this study is to examine if treatment of post-traumatic stress disorder in combat veterans with paroxetine changes brain responses as measured by functional magnetic resonance imaging and if brain responses can predict who will get better with treatment.
