Filter by:Sleep disturbance and posttraumatic stress disorder (PTSD) are common conditions in returning Veterans, and both conditions are known to increase the risk of cardiovascular disease. Research suggests that those with insomnia are at triple the risk of high blood pressure as compared to normal sleepers, and that having both insomnia and short sleep increases this risk to more than five times that of normal sleepers. These research findings suggest that recently deployed Veterans with insomnia may be at increased risk of developing high blood pressure, and this possibility is consistent with previous research. Vietnam era Veterans with combat-related PTSD assessed in 1985 were twice as likely to have died of early-onset heart disease relative to their non-PTSD counterparts when reassessed in 2000. Evidence for impaired cardiac function in individuals with PTSD has been demonstrated across several studies as well. Compared to individuals without PTSD, those with PTSD seem to have lesser reaction to stress in terms of both heart rate and heart beat pattern. However, there has been very little research examining the impact of behavioral sleep interventions on health outcomes, and even fewer that are specific to a PTSD or Veteran population. The purpose of this study is to determine if treating insomnia results in improved blood pressure and cardiac function in recently deployed Veterans with PTSD. The findings of this research will serve as pilot data for a future grant application testing the efficacy of Cognitive-Behavioral Therapy for Insomnia (CBTI) for reducing cardiovascular risk in Veterans with PTSD using a full-scale randomized trial design. We are hypothesizing that improved sleep will be significantly associated with improved blood pressure and increased heart rate variability (improved autonomic function) in adults receiving CBTI compared to those in a wait-list control condition.
The purpose of this study is to determine whether 60-minute sessions of prolonged exposure (PE) are as effective as the standard 90-minute session for treating posttraumatic stress disorder (PTSD). Participants will include patients ages 18 or older with a current diagnosis of PTSD who are seeking treatment in our clinic. Patients who have current substance dependence, psychosis, and suicidal ideation with intent and plan may not be suitable for receiving PE and may be offered another treatment or referred to a different treatment center. Participants will be randomized to receive either the 90- minute or 60-minute PE session. A blind evaluator will assess for pre-treatment, post-treatment, and follow-up levels of symptom severity using the PTSD Symptoms Scale Interview (PSS-I). Participants will attend weekly treatment sessions with any of our faculty members and will complete self-report measures at every session (see below).
The overall aim of this pilot feasibility study is to determine if 12-week moderate intensity exercise can safely alleviate posttraumatic symptoms in premenopausal women veterans. Specific aims of the study are to; 1. Determine the feasibility, safety, and tolerability of 12-week moderate intensity exercise 2. Explore potential therapeutic benefits of 12-week moderate intensity exercise. Outcome data will include posttraumatic and depressive symptoms. 3. Explore potential therapeutic effects of a 12-week moderate intensity exercise on comorbid pain syndrome and quality of life.
Approximately 9% of Canadians will have Posttraumatic Stress Disorder (PTSD) in their lifetime. In the military veteran population, the lifetime prevalence of PTSD has been estimated to be as high as 20%. Numerous research studies have demonstrated that short-term, cognitive-behavioral psychotherapies, such as Cognitive Processing Therapy (CPT), lead to substantial improvements in PTSD symptoms. However, research suggests that a minority of clinicians provide these therapies in clinical settings. The transfer of this research knowledge into clinical settings remains one of the largest hurdles to improving the health of Canadians with PTSD. It is well established that attending a 2-day workshop on these therapies alone is insufficient to promote adequate knowledge transfer and sustained skillful use. The current study aims to contrast whether two forms of post-workshop support (6-month duration), with different levels of expert oversight, will result in superior levels of clinician skill and patient outcomes versus no formal post-workshop support. The three forms of post-workshop support are 1) technology-enhanced group tele-consultation 2) standard group tele-consultation 3) no tele consultation. The primary and secondary outcomes will be the assessment of the clinicians' competence in CPT and patient symptoms,respectively. This study will inform how best to transfer evidence based therapy outcomes to the clinical milieu to attain comparable outcomes as those observed in research. The investigators' hypotheses are as follows: Hypothesis 1:The technology enhanced group tele-consultation condition will evidence the highest levels of fidelity, the standard group tele-consultation condition will evidence intermediate levels of fidelity, and the no-consultation/fidelity monitoring only condition will evidence the lowest fidelity. Hypothesis 2: Fidelity to the CPT protocol, irrespective of consultation condition, will be positively associated with improved client outcomes. Hypothesis 3: Organizational context variables, such as the organizational climate and readiness for change, will influence the uptake of CPT skills, as well as the extent to which these skills are utilized in practice.
A diverse body of research has implicated the amygdalo-cortical circuitry in the pathophysiology of anxiety disorders. For example, one model of PTSD posits exaggerated amygdala responsivity to threat-related stimuli as well as deficient top-down modulation of amygdala responses by specific cortical regions, including the pregenual anterior cingulate cortex, subcallosal cortex, and hippocampus. The investigators propose to investigate the pathophysiology of several specific anxiety disorders, Posttraumatic Stress Disorder (PTSD), Panic Disorder (PD), and Specific Phobia(SP), by using cognitive activation paradigms and magnetic resonance imaging (MRI) to probe the function and structure of implicated amygdalo-cortical circuitry.
The purpose of the study is to assess the dying process in critically ill patients with decision to withdraw invasive mechanical ventilation in anticipation of death and to compare effects of extubation and those of terminal weaning of mechanical ventilation on relatives and care givers. The investigators primary hypothesis is that extubation is associated with less symptoms of post-traumatic stress disorders in relatives, as compared to terminal weaning.
Although evidence-based treatments for PTSD exist, a significant minority of individuals do not benefit from these treatments and many individuals to not seek treatment, citing barriers such as time commitment and expense of treatment. The goal of the proposed study is to establish an alternative PTSD treatment that is efficacious and efficient.
The objective of this proposal is to collect pilot data to characterize the binding of [11C]MENET in combat-exposed war veterans with posttraumatic stress disorder (PTSD). Approximately two hundred thousand veterans will be returning stateside upon the end of combat operations in Iraq, and 13% of returning veterans will have PTSD. 15% of all war veterans will develop chronic PTSD symptoms requiring a lifetime of mental health care. Little is known about the dysregulation of PTSD veteran's neurochemical state including the noradrenergic system which plays a primary role in memory and stress response. This includes heightened anxiety, fear and hyperarousal symptoms characteristic of PTSD. The noradrenergic system is a concentration of neurons in the brainstem nucleus, locus coerulues, that have projections to the amygdale and prefrontal cortex. The norepinephrine transporter (NET) is responsible for regulating and terminating noradrenergic transmission, and is a specific marker for neuronal integrity. Hyperactivity of the noradrenergic system up-regulates NET protein. An unresolved problem in studying the noradrenergic system is identification of suitable radiopharmaceutical to non-invasively measure alterations in the density of NET. The investigators propose to address this challenge by using positron emission tomography (PET) to measure stress-induced changes in NET expression in combat-exposed war veterans with PTSD. The central hypothesis of this proposal is that war veterans with PTSD have an up-regulation of NET in the locus coerulues resulting from hyperactivity of the noradrenergic system compared to healthy controls. Through a series of experiments, the investigators will determine the in vivo binding characteristics of [11C]MENET. The investigators will use this information to optimally design an experimental protocol to measure the availability of NET in a pilot group of combat-exposed war veterans with PTSD. The aims of this proposal are: 1) Measure the uptake kinetics and whole brain distribution of [11C]MENET in combat-exposed veterans with PTSD and healthy controls, 2) Develop a quantitative kinetic model of [11C]MENET uptake to calculate the NET availability in brain. The subjects undergoing imaging in this work will be recruited by Dr. J. Douglas Bremner (Co-Investigator) at Emory University and Atlanta Veteran Affairs Hospital. Our long-term goal is to develop a longitudinal study framework to assess the NETs dysregulation during onset of PTSD as well as its transition to chronic lifetime PTSD.
Posttraumatic stress disorder (PTSD) is a debilitating psychiatric disorder that can develop after a traumatic life experience that severely reduces quality of life. This Phase 2 pilot study examined the safety and efficacy of MDMA-assisted psychotherapy in 23 subjects with chronic, treatment-resistant posttraumatic stress disorder (PTSD). This study is part of a global series of Phase 2 pilot clinical trials. This randomized, double-blind, dose response study assessed two active doses of MDMA, 100 mg and 125 mg, to a comparator dose of MDMA (40 mg) during psychotherapy sessions. The initial dose was followed 1.5 to 2.5 hours later by an optional supplemental dose of MDMA that was half the size of the first dose. MDMA was administered in two experimental sessions lasting up to eight hours and scheduled three to five weeks apart. Subjects were prepared for MDMA-assisted psychotherapy prior to the first session in three preparatory sessions, and worked with the same pair of therapists throughout the study. After each MDMA-assisted psychotherapy session, subjects had three integrative sessions with their therapist team to process and understand their experience. This study assessed the change in symptoms of PTSD, as measured by the Clinical Administered PTSD Scale (CAPS) [Blake et al., 1995], as well as symptoms of depression, as measured by the Beck Depression Inventory II (BDI-II) [Beck, A.T. and R.A, 1984; Beck, A.T., et al., 1996] from baseline enrollment to one month after the second MDMA-assisted psychotherapy session (primary endpoint). Participants who received the comparator dose of MDMA (40 mg) were given the option to enroll in Stage 2, where they underwent three open-label MDMA-assisted psychotherapy sessions with an active dose of MDMA. People who received either of the active doses of MDMA in Stage 1 had a third MDMA-assisted psychotherapy session with another active dose of MDMA.
Strengthening Families Coping Resources (SFCR) Open Trials completes the second stage of the National Institute on Drug Abuse's intervention development model by testing a new family, skills-based intervention involving pre-post evaluation of families participating in multi-family groups. The purpose of this study is to gather practice-based evidence on the effectiveness of the manualized treatment, on the dynamics involved in the group format, and on implementation fidelity and feasibility. Analyses will involve initial exploration of the following hypotheses: 1) Families will show a significant increase in the constructive use of family coping skills and in general family functioning. 2) The target child will show a reduction in trauma-related symptoms and behavior problems. 3) Parents will show significant reductions in traumatic stress and other symptoms of distress. 4) Families will engage and participate in the treatment. 5) Providers will implement SFCR with fidelity. Other outcomes of interest are the process measures that will be collected to monitor participation in the groups, cultural sensitivity and acceptability, clinician competence, and intervention integrity.
