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

Context: Since March 2012, several terrorist attacks have been perpetrated in France (Toulouse, Montauban, Paris, Nice ...). In March 2017, 53 french teenagers were victims in a terrorist attack in London (Westminster Bridge). Main goal = to estimate the psycho-traumatic impact and to describe cares and management of high school students, victims of the terrorist attack in London on 2017, March the 22nd. 3 secondary objectives: 1) Clinical (occurrence of Post Traumatic Stress Disorders or other disorders); 2) Epidemiological (risk factors for developing disorders, avoiding care); 3) Preventive and therapeutic.

The current study evaluates psychological and physical health outcomes for active-duty service members following participation in an established surf therapy program. Participants complete assessments before and after the surf therapy program, as well as brief assessments before and after each surf therapy session.

Neurofibromatosis type 1 (NF1) is one of the most common autosomal dominant genetic disorders. The aim of our study was to evaluate post-traumatic stress disorder (PTSD) in patients and their families following the disclosure of sporadic NF1. Diagnosis of NF1 was retained according to NIH criteria, familial forms were excluded. The French version of the Impact of Event Scale-Revised was used for the diagnosis of PTSD.

Most people will experience a psychologically traumatic event, such as a life-threatening accident, at some point in their life. In the initial days after such an event, it is common to be haunted by intrusive memories: image-based memories of the event that spring to mind unbidden. Intrusive memories can be distressing in their own right, but are also a hallmark symptom of post-traumatic stress disorder (PTSD). Sleep is important for many functions involved in how people perceive, respond to and remember events, including stressful/traumatic events. Studies with patients who have experienced traumatic events indicate that sleep disturbances in the first weeks post-trauma are associated with later PTSD symptoms. However, in a previous study with healthy volunteers exposed to experimental trauma (film footage), those who were sleep-deprived in the first night, compared to those who slept, had fewer intrusive memories in the following week. This raises the question of how sleep in the first night, but also the first week, after real-life trauma is related to subsequent intrusive memories and PTSD symptoms. The current study is an observational study of patients recruited from a hospital emergency department after a traumatic event. After completing brief baseline questionnaires in the emergency department, participants will be asked to fill in a daily diary of their sleep and intrusive memories over the following week. Post-traumatic stress symptoms, anxiety and depression will be assessed by post/online at one week and two months. Participants will be telephoned after two months to complete an interview to assess PTSD symptoms and an optional feedback interview. This clinical study will be the first to assess the relationship between sleep in the first night and week, and intrusive memories and mental wellbeing after real-life trauma. Findings may have implications for developing simple sleep-based preventive treatments after trauma in the future.

Post-traumatic stress disorder is associated with altered processing of sensory stimuli. The clinical phenotype PTSD has predominantly been described for the visual and auditory sensory modalities. However, PTSD symptoms such as intrusive memories are often evoked by olfactory and tactile cues in the environment. Moreover, little is known about whether aberrant responses to social olfactory and tactile stimuli are also present in a subclinical population.The purpose of this study is to compare trauma-exposed subjects (e.g. childhood maltreatment) with non-exposed controls in the processing of olfactory and tactile stimuli. This sensory characterizations hold potential to identify potential biomarkers for the course of trauma-related disorders and to inform trauma therapies focusing on sensory integration.

PRIME aims to demonstrate through neurocognitive assessment that BICU patients will have a degree of neurocognitive dysfunction following a major burn, that this neurocognitive dysfunction is due to an underlying neuroinflammatory process by fMRI neuroimaging techniques, and that the neurocognitive deficit is associated with a reduced quality of life.

Anxiety and depression are symptoms frequently met in ICU patients and relatives. Risk factors are known: disease severity, age, gender. Another risk factor is lack of information from the medical staff and nurses. Anxiety and depression can be measured by the Hospital Anxiety and Depression Scale (HADS). Other scales are used in the psychiatric field : the Impact Event Score - Revisited (IES-R) is relevant to detect Post-Traumatic Stress Disorder (PTSD), The Short Form Health Survey (SF-36) is an assessment of life quality. In the following study, the investigators will evaluate the impact of a "brochure" as complement of oral information on Anxiety developed by relatives and family of ICU patients. The medical and surgical ICU is composed by two different units (different medical and nurse team, different location in the same hospital) of 12 beds on one side, 14 beds on the other side. During a year, in the first unit, the investigators will use the booklet as support and complement of oral information : "booklet arm". The information process will be as usual in the other unit : "control arm". During the second year, the booklet will be used in the second unit while the first unit will return to the usual oral information (cross-over). For each included patient, one relative or family member is pointed to be the referring family member or "referent". This "referent" receives the HADS questionnaire at Day 3 after admission, at day of discharge if the patient is alive, at one month after discharge. The IES-R questionnaire is delivered at discharge of the living patient and at day 30. The SF-36 questionnaire is given to the "referent" and the living patient at day 30. The day 30 questionnaires are send by mail at the "referent" address.

A survey (patient self-report) of patients presenting to UAB emergency room, outpatient trauma clinics and substance abuse center for symptoms of post-traumatic stress disorder and maladaptive coping responses after the widespread tornado disaster that occurred in Alabama in April 2011.

Patients with post-traumatic stress disorder (PTSD) have abnormalities in the function of the amygdala and medial prefrontal cortex (particularly anterior cingulate), in addition to abnormalities of hippocampal volume. In this pilot study we propose to use the combined positron emission tomography/magnetic resonance (PET/MR) scanner and F-18-fluorodeoxyglucose (FDG, an analog of glucose, the most commonly used PET ligand) to examine brain function and directly correlate the data with the intrinsic functional connectivity of brain circuits that are responsible for social, emotional and cognitive processing in both individuals with PTSD and group-matched trauma controls (TC) and healthy controls (HC). Once the machine is validated, we will then use a more specific biomarker to better understand the neurochemical factors that contribute to individual differences in PTSD. Thus, the data obtained from this pilot study will guide our future molecular imaging studies. The link between general brain function, specific molecular target and the intrinsic functional connectivity of brain circuits that are responsible for social, emotional and cognitive processing in PTSD, TC and HC will be explored.

Relapse of post-traumatic stress disorder (PTSD) remains challenging. In addition, factors predicting PTSD relapse are still unknown. The aim of this study is to examine whether clinical and neuropsychological changes (e.g., attentional bias toward aversive cues) that characterized PTSD can be observed in people with past PTSD (children and their families) and whether these persistent changes are predictive of PTSD relapse.
