Active clinical trials for "Stress Disorders, Post-Traumatic"

This mixed-methods pilot study aim to assess the changes in symptoms of post-traumatic stress disorder (PTSD), complex post-traumatic stress disorder (CPTSD), dissociative symptoms, self-critique, and self-compassion following participation in a 16-week trauma-sensitive mindfulness and compassion (TMC) intervention. Adverse experiences of participation are also explored explicitly.

This study plans to examine if symptoms of PTSD affect how Veterans who have served in combat think and react to certain information, and whether or not this has an influence on suicidal thoughts.

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 this study is to determine whether the brains of persons with and without traumatic brain injury differ in a meaningful way when advanced technology images of the brain are taken using three newer technologies that visualize the brain using a combination of external/internal magnetic fields and radioactive tracers (molecules that emit detectable particles). The hope is that the results of this study will validate tools (help prove that diagnostic tools actually detect disease) for the diagnosis and treatment of traumatic brain injuries (TBI).

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.

This is an exploratory qualitative interview study being conducted with a primary objective of examining perceptions held by active military and veterans regarding help-seeking attitudes and mental health beliefs which influence the decision to consent or decline participation in Post-Traumatic Stress Disorder (PTSD) or Traumatic Brain Injury (TBI) clinical trials. Active duty military and/or veterans aged 18 years and older who consent to participate (N = 50), or have recently declined participation (N = 50), in an INTRuST affiliated outpatient clinical trial for deployment-related PTSD or TBI will be recruited. Participants who consent to participate in an INTRuST clinical trial (Group 1) will be interviewed once at the beginning the of the clinical trial, and again following participation in the trial. Participants who decline participation in an INTRuST affiliated outpatient clinical trial (Group 2) will be interviewed once. For participants in both groups, study participation will initiate within 1 month of referral to study. Total duration of study participation is based on the specific clinical trial that the participant is recruitment from; the longest trial is estimated to be 24 weeks or less. Semi-structured qualitative individual interviews will be conducted to carry out a thematic analysis of the data exploring familial, social and institution-level constructs which may influence the subjective experience of the research treatment process.

Objective psychophysiologic reactivity data may be useful for predicting post-traumatic stress disorder (PTSD) treatment response. Given the variety of PTSD treatments and the lack of a clearly superior treatment, a reliable and valid approach to predicting treatment response is needed. Specific Aims: 1). Evaluate the clinical utility of psychophysiologic reactivity measures to predict overall PTSD symptom response among OEF/OIF/OND (Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn) veterans receiving treatment for PTSD. 2). Evaluate the clinical utility of psychophysiologic reactivity measures to predict psychosocial functioning and health-related quality of life (HRQoL) response among OEF/OIF/OND veterans in treatment for PTSD. Exploratory). Develop psychophysiologic, neuropsychological, and/or self-report models to predict PTSD symptom response to pharmacotherapy, psychotherapy, and combined pharmacotherapy/psychotherapy. The investigators will divide psychophysiologic reactivity predictors into two groups: heart rate variability and attentional bias (eye gaze tracking and modified Stroop). The investigators will collect observational and longitudinal data from a treatment-seeking sample of 50 OEF/OIF/OND veterans with PTSD recruited from the Central Arkansas Veterans Healthcare System (CAVHS) Mental Health Clinics.

Trauma-informed treatment will improve emotional regulation and behavior.

The overarching aim of this Exploratory/Developmental Research Grant Award (R21) is to explore the neurobiological correlates of PTSD during REM sleep by using state-of-the science positron emission tomography (PET) sleep imaging. This study will allow us to gain insight into the differences in sleep and waking brain mechanisms between veterans with PTSD and those without PTSD.
