Filter by:PRIME aims to demonstrate through neurocognitive assessment that BICU patients will have a degree of neurocognitive dysfunction following a major burn, that this neurocognitive dysfunction is due to an underlying neuroinflammatory process by fMRI neuroimaging techniques, and that the neurocognitive deficit is associated with a reduced quality of life.
This study aims to develop and evaluate biomarkers using non-invasive optical coherence tomography (OCT) and OCT angiography (OCTA) as well as ultra-widefield (UWF) fundus photography to assess the structure and function of the retinal and choroidal microvasculature and structure in persons with mild cognitive impairment (MCI) and Alzheimer's Disease (AD), Parkinson's Disease (PD), or other neurodegenerative disease, diseases as outlined.
This pilot study investigated the trauma reducing effects of the Transcendental Meditation program on female prisoners The study was conducted over the 4 month period and measured total trauma symptoms at baseline and posttest in both the TM experimental group and waitlist controls
The purpose of this study is to evaluate the effects associated with the use of in-office High-resolution, relational, resonance-based, electroencephalic mirroring (HIRREM) for participants with symptoms of military-related traumatic stress. This is a single site, non-randomized, open label pilot study. Outcome measures collected before, and after the intervention evaluate effects on self-reported symptoms, autonomic cardiovascular regulation, functional measures, blood and saliva biomarkers of stress and inflammation, and network connectivity on whole brain, rest MRI testing. Self-reported symptom outcomes will also be collected remotely at 1, 3, and 6 months after completion of intervention. The study will assess feasibility in this cohort, focused on the Special Operations community, will provide estimates of effect size, and durability of symptom changes, while providing important pilot data for future proposals and investigations.
Posttraumatic stress disorder (PTSD) is prevalent mental illness (~9% life-time) that results from exposure to trauma. As it is associated with vastly heterogeneous origins, accurate diagnosis and optimal treatment strategies are sometimes very difficult to achieve. No known biomarker exists, which makes it difficult to assess treatment response and functional outcomes. The recent brain imaging studies have suggested that PTSD patients show abnormal brain connectivity measured by functional magnetic resonance imaging (fMRI). The investigators propose that cognitive processing therapy may ameliorate this functional connectivity abnormality which may be related with their symptomatic improvement.
Post-traumatic Stress Disorder (PTSD) is a debilitating mental disorder that affects approximately 7% of the general population. This project's aim is to develop a greater understanding of the efficacy and underlying mechanisms of narrative exposure based treatments for PTSD. Adult participants (N=162) who meet DSM-5 criteria for PTSD will be enrolled in a 3-arm randomized clinical trial consisting of trauma-related expressive writing, trauma-related expressive speaking, or a factual expressive writing control condition. Treatments will be manualized and conducted entirely through the Qualtrics survey platform. Treatment will consist of six sessions, three per week over two weeks, taking place via the internet. Assessments will be conducted pre-treatment, post-treatment, and at 1-month follow-up in the lab. Assessments will be comprised of symptom self-report measures as well as two tasks completed in an eye tracker: a reading task to evaluate mechanisms underlying trauma narrative processing and a sentence production task to evaluate attentional shifts when producing verbal information Specific Aims and Hypotheses: 1. Develop and test the relative efficacy of two cost-effective internet-based expressive trauma therapies (written vs. spoken) relative to a non-trauma writing control for PTSD. We hypothesize that both trauma-focused expressive therapies will achieve more favorable outcomes at posttreatment and follow-up on measures of PTSD and depression symptoms, posttraumatic growth, and quality of life compared to the writing control. 2. Conduct exploratory analyses testing baseline PTSD severity, depression severity, trauma type, time since trauma, and emotional engagement in moderating the differential effects of the selected expressive therapies. 3. Test the moderation of (1) active language processing with eye tracking (i.e. how long certain words are fixated on). (2) selected linguistic elements (i.e., frequency of emotional words, frequency of the pronoun "I"), (3) perceived self-efficacy to cope with trauma memories; (4) perceived threat appraisals associated with intrusive trauma memories on treatment outcome at follow-up. We hypothesize that (1) fewer and shorter fixations on ideographic (i.e. personally relevant) trauma words when reading the trauma narrative in the eye tracker will be associated with reductions in PTSD symptoms at follow-up. (2) increased use of emotional words over the course of writing sessions will be associated with reductions in PTSD and depression symptoms at follow-up; (3) pre- to posttreatment increases in trauma memory acceptance self-efficacy; and (4) pre- to posttreatment reductions in trauma memory threat appraisals will be associated with greater symptom reduction at the follow-up assessment.
Substance use disorders (SUDs) are a prevalent and impairing condition, particularly among trauma exposed individuals. The current proposal aims to address the critical need for targeted direct SUD prevention in this population by intervening on a novel, malleable risk factor for SUD common among trauma-exposed individuals: sleep disturbance. Sleep disturbance prospectively predicts the development of SUD and may confer risk for SUD by increasing stress reactivity, decreasing decision-making abilities, and ultimately promoting substance use to relieve negative affect, a core etiological factor in SUD. However, to our knowledge, no experimental studies have determined whether improving sleep leads to reductions in SUD risk. As such, the current study will use a randomized controlled trial design to test the effects of brief behavioral treatment for insomnia (BBTI) against a waitlist control among a sample of trauma-exposed young adults with poor sleep and risk for SUD (N = 60). We aim to determine the direct and indirect effects of condition (BBTI vs. waitlist control) on SUD symptoms, substance use-related problems, coping motives, and posttraumatic stress symptoms through improvements in sleep. Furthermore, we will test direct and indirect effects of condition on theoretically proposed mechanisms underlying the association between sleep disturbance and SUD risk (i.e., stress reactivity, cravings in response to stress).
Veterans who complete trauma-focused therapies (TFTs) report improvements in posttraumatic stress disorder symptoms, quality of life, and social and role functioning. However, many also report uncertainty regarding their ability to maintain and build upon progress made during TFTs following the end of treatment. Veterans who recently completed a course of TFT believe the likelihood of their ongoing success would be bolstered by mental health services that support additional practice and reinforcement of skills learned in TFT. Currently no evidence-based approach for post-TFT care exists; however, Veterans' reported treatment needs are well-suited to a therapist-assisted self-management approach. The objective of this project is to complete Stage 1 (intervention refinement and piloting) of the Stage Model of Treatment Development for a post-TFT therapist-assisted self-management program designed to help Veterans maintain or build upon gains made in TFT, increase self-efficacy for managing their PTSD symptoms, and enhance community engagement. The aims of the project are to: 1) Refine a self-management treatment protocol through eliciting feedback from experienced TFT providers on a draft of the self-management program, 2) Conduct a pilot open trial to assess the acceptability and feasibility of the self-management program, and 3) Explore the effects of the program on Veterans' confidence in managing their PTSD and Veterans' functioning, quality of life, community engagement, and mental health symptoms.
This research study is being done to try to find a way to accurately diagnose post-traumatic stress syndrome (PTSD) in combat veterans.Diagnostic biomarkers have made invaluable contributions to the diagnosis and treatment monitoring of many diseases and disorders. Unfortunately, PTSD currently lacks a reliable and compelling clinically-relevant biomarker. The absence of a viable biomarker impairs efficient and confident diagnosis of PTSD, with diminished effective care options often resulting.
The investigators will test whether intranasal oxytocin (24 IU vs placebo) will induce effects on attention bias and startle comparable to those the investigators have shown to be induced by the presence (vs absence) of a service dog in Veterans diagnosed with PTSD. This possibility is suggested by a 2015 study showing that urinary oxytocin levels are elevated in association with mutual gaze between dogs and their owners.
