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

This is a research study examining the use of two medications, Hydrocortisone and D-Cycloserine, compared to an inactive substance (placebo), on their ability to reduce fear responses and memory of fear in Veterans with symptoms of Posttraumatic Stress Disorder (PTSD). These responses will be tested using a fear learning and memory task administered by computer.

The purpose of the proposed research is to conduct a feasibility study of yoga as an adjunctive therapy for the treatment of posttraumatic stress disorder (PTSD) in 15 military personnel at the Walter Reed Army Medical Center (WRAMC) in Washington, DC. Participants will complete 10 weeks of yoga training, in addition to the continuing their usual and customary care for PTSD at WRAMC. The style of yoga chosen for this study, Yoga Nidra, uses deep relaxation, deep breathing and meditation to systematically reduce physical, emotional, mental, and even subconscious tension. After a diagnostic mental health assessment at baseline, participants will attend a total of 18 classes taught over a 10-week period and will practice daily at home using a compact disk provided by the instructor. Baseline measures will include the Patient Health Questionnaire, PD-HAT Trauma Questions, PTSD Symptom Scale - Interview, Fear of Loss of Vigilance Scale, and expectation of efficacy. The primary outcome measure will be the PTSD Checklist. Changes in health status, locus of control, and pain will be assessed over the course of the study. An additional goal of this study is to gather preliminary data on the anticipated effect size and feasibility of conducting a larger clinical study of the adjunctive use of yoga for the treatment of PTSD symptoms in enlisted military personnel.

Post-traumatic stress disorder (PTSD) is a serious illness, in which individuals often experience anxiety and stress. Some individuals with PTSD use drugs to alleviate emotional distress. This study will examine the role that negative emotional states play in sedative drug use among individuals with PTSD.

This study, conducted at the University of Pennsylvania and at the National Institutes of Health in Bethesda, Maryland, will examine deficits in brain structure and function in people exposed to trauma who developed post-traumatic stress disorder (PTSD) to see if these deficits change after treatment. It also will investigate whether there is a genetic susceptibility to PTSD. Candidates 18 years of age and older in the following categories will be included in this study: 1) women who have PTSD of at least 1 year's duration following sexual or non-sexual assault; 2) healthy women (controls) who were previously assaulted but did not develop PTSD; and 3) healthy women (controls) who were never traumatized. Candidates will be screened with a medical history and physical examination, psychiatric evaluation, electrocardiogram (EKG), and routine blood and urine tests. Women with PTSD will be assigned to receive either: 1) 12 weeks of cognitive behavioral psychotherapy either immediately upon enrollment or after a 3-month waiting period; or 2) 10 weeks of drug treatment with paroxetine (Paxil® (Registered Trademark)). Patients will be evaluated before and after treatment with the procedures outlined below. Control subjects will undergo the same procedures, also with a 10- to 12-week interval between evaluations. Neuropsychological testing: Subjects will take paper and pencil and computer tests to evaluate memory, learning, attention and concentration, vocabulary and naming. Magnetic resonance imaging (MRI): Subjects will have MRI scans of the brain to examine brain structure and blood flow while they perform two tasks. In the first task, they will be shown a series of faces and asked to press one button for a male face and another button for a female face. In the second task they will hear loud noises and see colored squares. During the scan, subjects lie on a bed that slides into a narrow tunnel (the scanner). They will wear a headset to block the noise of the scanner and through which they will receive instructions for the tasks. Heart rate and skin conductance (sweating) will be measured during the scan to evaluate physiologic changes in response to the tasks. Eyeblink air puff test: Subjects will hear tones and will have a light puff of air delivered to the eye. Changes in heart rate, sweat, and eyeblink will be measured with electrodes taped to the skin on two fingers, on each side of the rib cage, and under one eye. Potential air puff delivery: This experiment has three parts. During each of the three parts of this experiment, subjects will see colored lights and may or may not receive a puff of air to the neck. Before each part they will be told that they will, will not, or may receive an air puff to the neck. Each part will be repeated several times. During the test, electrodes will be taped to the arms and chest to monitor skin conductance and heart rate responses. Blood draw for genetic evaluation: Subjects' DNA will be examined to try to determine if the risk of developing PTSD is inherited. The DNA will be examined for cortisol receptor gene evaluation, to see if a form of this gene is found more often in patients with PTSD than in healthy controls. The receptor for cortisol determines the activity of the stress hormone cortisol, and genetic variations in the structure of this receptor may be related to vulnerability to PTSD. Patients taking paroxetine will be offered up to 3 months of additional drug therapy following completion of the study and will be offered participation in other NIH studies for evaluation and treatment of PTSD.

Using a touch screen computer, the researchers are screening emergency department patients for intimate partner violence and mental health issues.

Post-traumatic stress disorder (PTSD) is characterized by physiological changes, some of which are thought to be chronic, while others are observed in response to stressogenic stimuli. A psychiatric diagnosis of PTSD is currently based mainly on non-quantitative elements, such as interviews and subjective impressions. Discernable patterns of stress-related measures may constitute a physiological and biochemical phenotype characteristic of PTSD, which may serve as a biomarker and support diagnostic decisions, as well as personalized treatment plans. The current study is aimed at examining the possibility of basing a psychiatric diagnosis by measuring changes in the biochemical phenotype of participants with PTSD. Physiological and biochemical data will be collected from participants with and without PTSD using wearable sensors and adhesive biosensor patches. The data will be collected in two conditions: in a neutral, quiet situation, and during and following exposure to controlled stressogenic stimuli.

At the "Métropole Savoie" hospital, to deal with the daily influx of severe patients during the second wave of COVID-19, 23 patients had to be transferred away from their home city and far from their families as part of a medical evacuation (EVASAN). The purpose of the study is to investigate whether there is an association between medical evacuations and the occurrence of psychological disorders such as post-traumatic stress, anxiety or depression occurring within 6 to 10 months in families of evacuated patients. The investigators want to compare the prevalence of psychological disorders in the families of patients evacuated for a serious form of COVID-19 (cases) compared to that of families of patients not evacuated (controls) hospitalized for a serious form of COVID-19.

Neurofeedback (NF) is a form of treatment that can assist individuals in learning to control their brain wave activity. NF-studies have shown promising results in reducing PSTD-symptoms among military veterans, but there are no published peer-reviewed studies with refugees. However, preliminary studies from Malmö and Sydney indicate that refugees could benefit from NF. Therefore, at the Competence Centre for Transcultural Psychiatry (CTP) a longitudinal feasibility study, testing NF for trauma-affected was started. The study contains both a quantitative and a qualitative substudy. In in the quantitative substudy, where a total of 32 participants have been included, the aim was to evaluate the feasibility of NF with trauma affected refugees using a quantitative perspective. The NF intervention offered was 12 training sessions of 12-20 minutes NF, and the outcome measures were self-administered questionnaires and semi-structured interviews collected before and after the intervention. In a subsample of eight participants of those included in the quantitative substudy, qualitative in-depth interviews were carried out. The participants were offered two interviews; one before the first NF training and one during the treatment course. The aim of the qualitative substudy was to evaluate the feasibility of NF with trauma-affected refugees by examining the participants' thoughts and expectations prior to participating in NF treatment as well as their experience with the treatment after a few sessions.

This study will evaluate and describe the occurrence of Acute traumatic stress and persistence of Post Traumatic Stress Disorder (PTSD) after resuscitated sudden cardiac death (SCD) in patient and relatives present during the event. The population will be composed of 40 patients: 20 with resuscitated SCD and 20 relatives. Two interviews will be performed by a psychologist within one week after resuscitated SCD and at month 3. Questionnaire Stanford Acute Stress Reaction Questionnaire (SASRQ), Life Events Checklist for Diagnostic and Statistical Manual of Mental Disorders (DSM-5) (LEC-5) and Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5) will be filled during these interviews.

This research study is designed to investigate the use of a simple cognitive task (a memory cue and 10 minute time gap, followed by playing the computer game "Tetris") for decreasing the number of intrusive memories of trauma among young refugees and asylum seekers. The design is a single case experimental AB design with optional replication (ABAB). Participants will aim to complete a no-intervention phase ('A': baseline phase) of one week followed by a one-week intervention phase ('B'), including a one-session intervention with a researcher comprising the simple cognitive task, followed by instructions to continue to use the technique self-guided in the subsequent week. Follow ups are conducted after each week to monitor the occurrence of intrusive memories of trauma in a pen-and-paper diary. It is predicted that participants will report fewer intrusive memories during the intervention phase than during the preceding baseline phase.
