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

The goal of this study is to investigate a new treatment for chronic symptoms after concussion or mild traumatic brain injury in people aged 18-65 years old. Chronic symptoms could include dizziness, headache, fatigue, brain fog, memory difficulty, sleep disruption, irritability, or anxiety that occurred or worsened after the injury. These symptoms can interfere with daily functioning, causing difficulty returning to physical activity, work, or school. Previous concussion therapies have not been personalized nor involved direct treatments to the brain itself. The treatment being tested in the present study is a noninvasive, personalized form of brain stimulation, called transcranial magnetic stimulation (TMS). The investigators intend to answer the questions: Does personalized TMS improve brain connectivity after concussion? Does personalized TMS improve avoidance behaviors and chronic concussive symptoms? Do the improvements last up to 2 months post-treatment? Are there predictors of treatment response, or who might respond the best? Participants will undergo 14 total visits to University of California Los Angeles (UCLA): One for the baseline symptom assessments and magnetic resonance imaging (MRI) Ten for TMS administration Three for post-treatment symptom assessments and MRIs Participants will have a 66% chance of being assigned to an active TMS group and 33% chance of being assigned to a sham, or inactive, TMS group. The difference is that the active TMS is more likely to cause functional changes in the brain than the inactive TMS.

In January 2022, the World Health Organization (WHO) launched the 11th edition of the International Classification of Diseases (ICD-11). This diagnostic manual includes the new diagnosis of complex post-traumatic stress disorder (CPTSD). This new diagnostic category describes difficulties that may arise as a result of multiple, prolonged or repeated trauma, from which it is difficult or impossible to escape, such as torture, domestic violence or childhood sexual abuse. People affected by CPTSD often have difficulty regulating their emotions and maintaining relationships with others, and they often show a negative self-concept. Evidence from the field of cultural clinical psychology indicates cultural variation in the CPTSD symptoms across different cultural groups. In addition, psychopathology is shaped by structural factors such as inequality and/or discrimination. This research project aims to highlight such cultural and structural aspects related to PTSD and CPTSD among refugee populations in Switzerland. A diagnostic interview and a therapeutic manual will be culturally adapted and pilot tested with a small sample (n = 24).

The experience of a loved one's stay in a COVID-19 intensive care unit (ICU), either intubated or on respiratory support, forces family caregivers (hereafter 'caregivers') to face core existential fears, such as uncertainty and death. It also poses a serious threat to basic human needs for autonomy, competence, and relatedness, as family caregivers have no control over the illness, and limited prior competence in dealing with critical illness. COVID-19 likely aggravates this experience, as social distancing cuts caregivers off from visiting patients in the ICU, from using their usual social supportive network and the threat of infection extends to caregivers themselves, their children and family. Combined, these extreme circumstances put caregivers in emotional turmoil and in need of psychological support and assistance in managing difficult emotions. ICU caregivers are at risk of developing clinically relevant symptoms of anxiety or posttraumatic stress. During the patient's ICU stay, caregivers experience peri-traumatic distress, such as helplessness, grief, frustration and anger, that may predict later posttraumatic stress disorder (PTSD). Symptoms of anxiety and PTSD may last for months to years after the patient's discharge. Further, caregivers of patients who die in an ICU may be at greater risk of prolonged grief disorder. Supportive interventions may reduce psychological late effects in ICU caregivers, but the primary focus of the majority of interventions has been on communication or surrogate decision making. The CO-CarES study aims to develop and test the feasibility of a tele-delivered psychological intervention to enable caregivers of ICU patients with COVID-19 to better endure the overwhelming uncertainty and emotional strain and reduce the risk of posttraumatic stress and prolonged grief. The study hypothesizes that providing psychological intervention during and after the patients' hospitalization, can decrease peri-traumatic distress during ICU hospitalization and decrease risk of post-traumatic stress, anxiety, depression and perceived stress following discharge, as well as prolonged grief in bereavement. A secondary hypothesis is that changes in emotion regulation mediate effects of the intervention on long-term psychological outcomes.

This study will evaluate a program designed to increase military treatment facilities' use of Prolonged Exposure (PE), an evidence-based psychotherapy for PTSD. The results will determine whether this program increases PE use and improves patient outcomes compared to conventional provider training in PE, and feedback from clinic leaders and staff will be used to gauge program usability, identify successful components, and refine program for expansion.

Post-traumatic stress disorder (PTSD) is a complex disorder expressed as a variety of neurobiological symptoms, including anxiety, re-experiencing, hyperarousal, and avoidance symptoms, along with comorbidities such as anxiety, depression, and increased risk for self-medicating substance abuse. Currently, there are only two approved medications in the United States (US) for PTSD, paroxetine and sertraline. Psychedelic medications, including psilocybin, have recently received breakthrough designation by the US Food and Drug Administration (FDA) for other psychiatric indications. Although no formal clinical trials have yet investigated psychedelic substances for the treatment of PTSD, the available evidence warrants such an investigation. The present study aims to investigate the effect of psilocybin on treatment-resistant PTSD.

Approximately 20 million Americans suffer from Obstructive Sleep Apnea (OSA) creating risks for major health problems, including dementia, heart attack, and stroke. Obesity, a growing problem for Americans and Veterans alike, is the greatest risk factor for the development of OSA. Male gender and smoking, other OSA risk factors, are common in Veterans. Given the high comorbidity of these risk factors in Veterans, OSA presents a significant health burden to Veterans. The investigators' prior work provides evidence that OSA occurs in up to 69% of Vietnam-era Veterans with PTSD. OSA is easily treated; however, 15-30% of OSA patients are non-compliant with continuous positive airway pressure (CPAP), the standard OSA treatment. The proposed research aims to facilitate adherence to CPAP treatment by testing a novel cognitive-behavioral therapy intervention in Veterans with PTSD. If successful, it may represent an approach that could be applied to the rehabilitation of other chronic conditions with similar barriers to care.

In this study, individuals with and without post-traumatic stress disorder (PTSD) will undergo one positron emission tomography (PET) scan using the radiotracer [11C]PBR28, which binds to the 18kDa translocator protein (TSPO). A subset of individuals who complete the first PET [11C]PBR28 scan will be invited to complete an inflammatory challenge and second PET [11C]PBR28 scan. Approximately 3 hours prior to the second [11C]PBR28 PET scan, lipopolysaccharide (LPS; endotoxin) will be administered to evoke a robust neuroimmune response. Subjects will also undergo behavioral and cognitive testing. Vital signs, subjective response, and peripheral biomarker levels will be assayed periodically throughout the experimental session. Specific aims: 1) Determine if individuals with PTSD exhibit neuroimmune system disruption relative to well-matched comparators at baseline. 2) Determine if individuals with PTSD exhibit a disrupted neuroimmune response after a classical immune stimulus relative to well-matched comparators. 3) Determine if LPS differentially alters cognitive function, subjective response, or physiological markers in individuals with PTSD compared to well-matched comparators. Hypothesis: Individuals with PTSD will exhibit a suppressed neuroimmune system at baseline and an attenuated neuroimmune response following LPS challenge, relative to matched trauma controls.

Despite carrying the vast majority of the global mental disorder burden, 75% of adults with mental disorders in Low and Middle Income Countries have no access to services. This study will test strategies for integrating first and second line evidence-based depression and trauma-related disorder treatments with primary care services at a large public sector hospital and conduct robust cost and cost-benefit analyses of each treatment to produce a "menu" of cost-benefit options for personalized, integrated mental health care with corresponding effectiveness and implementation values.

This study will deploy a scalable secondary prevention program that leverages existing foster youth transition services to improve mental health functioning and service use before and after exiting foster care. Our short-term objective is to remotely test a group intervention called Stronger Youth Networks and Coping (SYNC) that targets cognitive schemas influencing stress responses, including mental health help-seeking and service engagement, among foster youth with behavioral health risk. SYNC aims to increase youth capacity to appraise stress and regulate emotional responses, to flexibly select adaptive coping strategies, and to promote informal and formal help-seeking as an effective coping strategy. The proposed aims will establish whether the 10-module program engages the targeted proximal mechanisms with a signal of efficacy on clinically-relevant outcomes, and whether a fully-powered randomized control trial (RCT) of SYNC is feasible in the intended service context. Our first aim is to refine our SYNC curriculum and training materials, prior to testing SYNC in a remote single-arm trial with two cohorts of 8-10 Oregon foster youth aged 16-20 (N=16). Our second aim is to conduct a remote two-arm individually-randomized group treatment trial with Oregon foster youth aged 16-20 with indicated behavioral health risk (N=80) to examine: (a) intervention group change on proximal mechanisms of coping self-efficacy and help-seeking attitudes, compared to services-as-usual at post-intervention and 6-month follow-up: and (b) association between the mechanisms and targeted outcomes, including emotional regulation, coping behaviors, mental health service use, and symptoms of depression, anxiety, and PTSD. Our third aim is to refine and standardize the intervention and research protocol for an effectiveness trial, including confirming transferability with national stakeholders.

Individuals with posttraumatic stress disorder (PTSD) have greater prevalence of alcohol use disorders (AUDs), with this comorbidity associated with worse illness outcomes, yet there remains limited mechanistic understanding of how PTSD confers risk for AUD. Understanding risk factors that associate with and predict the development of AUDs in PTSD could inform interventions and prevention efforts to reduce the rate of this comorbidity and improve outcomes of both disorders. Identifying predictors of risk requires longitudinal studies in PTSD aimed at capturing the mechanisms leading to the emergence of AUDs. There is growing evidence PTSD is related to biased decision-making during approach-avoidance conflict. Alcohol is also suggested to alter approach-avoidance decision-making. AUDs and acute alcohol intoxication is associated with a bias to seek out reward despite the possibility of threat (e.g., contributing to relapse following alcohol cue exposure and risky behavior during intoxication respectively). Alcohol-induced changes in approach-avoidance decision-making have not been investigated in the context of PTSD, but emerging data support the investigators' hypothesis that an interaction between alcohol and approach-avoidance conflict in PTSD may occur and contribute to risk for alcohol misuse and development of alcohol problems. No current data, cross-sectional or longitudinal, have tested the role of alcohol-induced changes in approach-avoidance conflict as a mechanism of risk for AUD among individuals with PTSD. To address this gap, the investigators propose to leverage the group's expertise in placebo-controlled alcohol administration procedures, longitudinal modeling, functional neuroimaging, and computational neuroscience approaches to investigate the effects of acute alcohol on approach-avoidance decision-making and mediating changes in multivariate neurocircuitry patterns in limbic, striatal, and salience networks.
