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

Posttraumatic stress disorder (PTSD) is a disabling psychiatric disorder that affects 20%-30% of U.S. Veterans. PTSD is strongly associated with increased risk for substance abuse comorbidity, including cannabis use disorder. Multiple states now include PTSD as a condition for which patients can be legally prescribed medical marijuana, despite the fact that there has not been a single large-scale randomized clinical trial demonstrating the efficacy of cannabis to treat PTSD to date. The overall objective of the current proposal is to study the impact of reduced cannabis use on functioning among Veterans with PTSD. The investigators will evaluate the relationship between cannabis use and daily functioning among cannabis users and heavy cannabis users. The central hypothesis is that reductions in cannabis use will lead to positive changes in the functional outcomes of Veterans. The rationale for this research is that it will provide the first and only real-time data concerning the impact of reduced cannabis use on daily functioning among Veterans with PTSD.

The goal of this study is to look at how a type of drug called cannabinoids are related to the processing of fear signals, the experience of emotions and fear, and the pattern of activity in the brain that is involved in these processes and how this relates to the treatment of post-traumatic stress disorder (PTSD). PTSD is an anxiety disorder that occurs after experiencing a traumatic event(s) and is characterized by unwanted memories of the trauma(s) through flashbacks or nightmares, avoidance of situations that remind the person of the event, difficulty experiencing emotions, loss of interest in activities the person used to enjoy, and increased arousal, such as difficulty falling asleep or staying asleep, anger and hypervigilance. The information gained from this study could lead to the development of new treatments for persons who suffer from anxiety or fear-based disorders.

This research aims to confirm that the therapeutic effect of EMDR is associated with changes in the interaction between cognitive function and emotional stimuli in PTSD patients compared to a controlled therapy in a randomized, single-blind study.On the other hand, this study aims to observe neuronal and cognitive correlates related to EMDR therapy compared to a control therapy. This investigation would improve the understanding of the mechanisms of action of the EMDR, still unknown to date.

Purpose: About 6.4% of the U.S. population suffers from posttraumatic stress disorder (PTSD). Trauma-focused psychotherapies are generally effective in PTSD, but responses vary greatly across individuals and PTSD subpopulations. Neurobiological factors impacted by life experiences, stress, and genetics can affect treatment responses. These factors can alter brain capacities needed to reprocess traumatic memories prevent them from triggering intensely distressing, disruptive, out-of-place responses. For example, during psychotherapy for PTSD, trauma memory activation engages two competing brain processes that affect recovery: "extinction" versus "reconsolidation" of trauma-related emotional, physiological, and behavioral responses. This study tests whether a single intravenous (IV) dose of allopregnanolone (Allo) compared to placebo (which is non-active): promotes consolidation of extinction learning (sub-study 1) or blocks reconsolidation physiological responses triggered by aversive memories (sub-study 2). The study also tests whether Allo compared to placebo affects retention of non-aversive memories.

Recent Veterans of the Afghanistan and Iraq conflicts are presenting in VA care with high rates of posttraumatic stress disorder (PTSD), depression, anxiety, and substance use disorders. Difficulties with social relationships and community reintegration are common functional impairments with these disorders. VA is transforming to a Whole Health, patient-centered system of care that will address these issues as part of health care. In a previous study, Omnis Salutis (OS) was developed with Veteran and clinician input. OS is a three-session intervention in which Veterans learn about Whole Health and practice communicating their health mission to providers and social supports. OS was shown feasible to deliver, acceptable to Veterans, and preliminarily effective at improving physical, mental, and social functioning. This study will use a large, multisite randomized controlled trial to test the impact of OS on Veterans' social and physical functioning and Veteran engagement in mental health care. Results will support broad delivery of OS throughout the VA.

Displaced people, like refugees or asylum seekers, have high rate of potentially traumatic events. PTSD is one of the most common psychiatric trouble in this population. It requires specialized support and psychosocial program. Narrative Exposure Therapy (NET), a german psychotherapy, was developed in the 2000 to specifically treat psycho-trauma in this population. It is brief, effective on complex trauma and can be delivered by trained non-caregivers. All published randomized studies have conclued that NET is effetive, but there are still insifficient numbers to make recomendations. To our knowledge, NET has never been tested in France. In Marseille, SINDIANE is a community support and program for refugees and asylum seekers. Many workshops led by peer workers are offered to increase empowerment of beneficiaries and hel them to recover. The development of a NET workshop would make it possible to combine community support and specific and validated psychotherapy. Through this study, the investigators hypothesize that tratment of PTSD with NET in the community-based SINDIANE program decrease symptoms of PTSD.

The proposed study will assess the combined effect of perampanel and ketamine on the anti-depressant response in individuals with treatment resistant depression. The purpose of this study is to test the hypothesis that stimulation of Alpha-Amino-3-Hydroxy-5-Methyl-4- Isoxazole Propionic Acid receptors (AMPAR) is critical to the anti-depressant response of ketamine.

This study aims to address barriers to psychosocial care for siblings of children with cancer by piloting a group-based telehealth program for adolescent siblings of youth with cancer. The pilot trial will be preceded by a treatment development stage during which study staff will interview English- and Spanish-speaking families and psychosocial providers to assess preferences for program content, format, timing, and cultural feasibility and acceptability, while considering ideas to minimize participation barriers. Information from interviews will inform any revisions to the proposed pilot program. Then, the new SibACCESS program will be tested with a small group of families located in Massachusetts, Delaware, or Rhode Island using video-teleconferencing technology. Families will complete exit interviews to assess program acceptability and perceived benefits.

The investigators will complete an entirely remote randomized controlled trial (RCT) comparing 14 sessions of attention bias modification (ABM), attention control training (ACT), placebo neutral attention training, and a final control condition with daily questions in 1,897 individuals with clinically significant Post-traumatic Stress Symptoms (PTSS) (defined as PCL-5 score ≥ 33). To assess effects of the training and control conditions, the investigators will administer tests of threat-related attention bias and variability, and self-report assessments of PTSS, depression, anxiety, and perceived stress at baseline, after one and two weeks of training, and at eight-week follow up. The investigators plan to screen and confirm interest from over 3,000 eligible participants over a period of 24 months to enroll and randomize 1,897 participants with the end goal of 1,232 completers (176 per condition).

The primary purpose of this study is to investigate the effects of tDCS timing on safety memory in PTSD. A total of 90 participants will be randomized equally across one of three groups: One group receiving active stimulation during extinction and sham during consolidation One group receiving sham stimulation during extinction and active during consolidation One group receiving sham stimulation both during extinction and consolidation This study will also include an online sub-study focused on contextual processing along the PTSD spectrum. A maximum of 500 participants will be recruited using an online, panel-based platform.
