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

This is a single-arm, open-label feasibility study. A maximum of 15 participants will be enrolled. All participants will undergo a novel neurofeedback intervention, targeting down-regulation of deep limbic structures, specifically the amygdalae. Participants will complete 12 neurofeedback sessions delivered twice weekly over 6 consecutive weeks. The intervention will be delivered via the PRISM platform.

Background: - Some people who have a traumatic brain injury (TBI) recover completely. Others, however, develop post-traumatic stress disorder (PTSD), with anxiety and depression. Research suggests that levels of a brain chemical called GABA may differ in people with PTSD compared to those without PTSD. Researchers want to see if TBI can affect GABA in the brain and help develop PTSD. To look at the brain, researchers will use imaging studies with the chemical 11C-Flumazenil, which will help the scan show GABA levels in the brain. Objectives: - To study the relationship between PTSD and TBI. Eligibility: The subjects will be recruited from the Walter Reed National Military Medical Center (WRNMMC). Individuals between 18 and 50 years of age who have PTSD and/or had a mild TBI. Healthy individuals between 18 and 50 years of age who have no history TBI and no history of PTSD. Design: Participants will be screened with a physical exam and medical history. Urine and breath samples will also be collected. Participants will have two imaging studies, on the same day if possible. The first will be a magnetic resonance imaging scan to look at the brain. The second will be a positron emission tomography scan with the study chemical to look at GABA pathways in the brain....

The objective of this study is to evaluate whether use of TRMDU in addition to medication review leads to improved outcomes and reduced health care costs for patients when compared with medication review alone. The study will be conducted in patients assigned to Department of Defense (DOD) Warrior Transition Units (WTU's), similar DOD units, and VA polytrauma centers.

This prospective, observational, multicentre study evaluates the existence of Post-traumatic stress disorder following a stroke at 3 and 6 months after the management of the patient. Questionnaires will be used to assess the presence of stroke post traumatic disorder. The evaluation of stroke post traumatic disorder would allow to underline the importance of the awareness of the care teams in the the screening of these disorders and to evaluate if the Post-traumatic Stress Disorder Checklist Scale (PCL5) is an effective screening tool.

The purpose of this study is to learn about how trauma, posttraumatic stress disorder (PTSD), and mild traumatic brain injury that can occur during deployment affect the brain. The investigators also want to learn how PTSD and mild traumatic brain injury can affect the chance of developing Alzheimer disease later in life. The investigators will study this by using magnetic resonance imaging and positron emission tomography scans to obtain pictures of the brain.

Post-traumatic stress disorder, PTSD, is one of the most prevalent psychiatric disorders. As casualties of motor vehicle accidents, criminal acts or terrorism are arriving to the ER, it is almost impossible to conclude who will overcome his psychiatric trauma and will be able to return to his normal life course and who will be thrown out of his promising life trajectory. Current attempts to identify those who are at the greatest risk are still unsatisfactory, which comprise a therapeutic dilemma, since the interventions used to ameliorate and prevent the occurrence of PTSD in a high-risk patient, might be counter-productive and even precipitate the emergence of PTSD in lower-risk patients. Since PTSD is closely related to the "Fight, Flight or Freeze" reaction, it has much to do with the autonomic nervous system and the major stress hormone, cortisol. Despite many studies demonstrating the involvement of those factors in the development of PTSD, various attempts to profile the direction of the association between PTSD and cortisol abnormalities have yielded conflicting results. The introduction of a novel method of assessing the excretion of cortisol using residues in the human hair shaft, has allowed an unprecedented evaluation of its activity over a prolonged period of time. Using this novel method of cortisol assessment, the investigators aim to identify biomarkers that will be able to aid in the prediction of PTSD development ahead of symptoms emergence, and will enhance the understanding of the physiological mechanism involved and etiology of this disorder.

The goal of this exploratory, mixed-method design study is to gather qualitative and quantitative data obtained through interviews and questionnaires with veterans who are currently enrolled at the VA for healthcare. The main question this study aims to answer is: How do veterans diagnosed with PTSD and enrolled for care at the VA understand MDMA-assisted therapy for PTSD? Using a story-completion approach, participants will be provided with a brief story starter involving a fictitious character and scenario and asking them to complete the story. Few contextual details will be offered about the character. In responding to ambiguous cues, participants are thought to project their conscious and subconscious perceptions about the phenomenon in question onto the story, a useful method for exploring stigmatized topics. The purpose of this exercise is to ascertain the participants attitudes and perceptions regarding MDMA-Assisted Therapy.

Participants with Borderline pathology (≥ 3 DSM-IV-criteria) receiving an inpatient Dialectical Behavior Therapy (DBT) program completed a quality assurance questionnaire set assessing demographic information and pretreatment psychopathology during the days of their inpatient stay. Beyond that, changes of therapists were documented.

The aim of this study is to identify if an avalanche accident has a psychological impact on avalanche victims. The investigators hypothesize that being exposed to an avalanche could generate enough stress to develop posttraumatic stress symptoms or even more, an authentic posttraumatic stress disorder (PTSD). Additionally, the investigators think that such symptoms might lead to physical and psychological distress in daily life. Lastly, the investigators suppose that a serious traumatism, a complete and/or prolonged burial, the death of a family member or a closed friend could be a potential risk factors to develop PTSD symptoms in avalanche victims. To evaluate post traumatic stress symptoms and the quality of life of avalanche survivors, the investigators use the Impact of Event Scale - Revised and the Short Form 12. These two scales are included in a standardized questionnaire, which is submitted to avalanche victims during a phone call.

The mental health of the French population in response to covid-19 pandemic is of concern. Health professionals are prone to more mental disorders due to their direct exposure to the pandemic consequences. Indeed, compared to general population, health care workers face enormous in the current health situation, especially those who may be in contact with suspected or confirmed cases (risk of infection, inadequate protection, loss of control, lack of experience in managing the diseases, overwork, stigma, lack of support). Thus, it seems interesting to describe the psychological state of hospital interns during this pandemic.
