Active clinical trials for "Stress Disorders, Traumatic"

Quarantine related to the Covid-19 pandemic has begun on the 03/17/2020 in France. Quarantine has already be linked to pejorative effects on mental health. In this study, we aim to evaluated PTSD symptoms of patients already followed by a psychiatrist during quarantine, one month and 3 months after inclusion. It will be also evaluate various psychiatric symptoms.

Anxiety disorders are characterized by exaggerated levels of fear that are not proportional to the actual level of threat. More specifically, anxiety patients have marked deficits in the downregulation of fear reactions during situations of objective safety. Pre-clinical research on Pavlovian fear conditioning and extinction has discovered that fear downregulation stems from areas in the prefrontal cortex (the ventro-medial prefrontal cortex, vmPFC) that recruit intercalated cells in the amygdala to inhibit its central nucleus, which is responsible for a variety of behavioral expressions of fear (Milad & Quirk, 2012). Accordingly, functional magnetic resonance imaging studies (fMRI) revealed reduced vmPFC activity coupled with increased fear reactions during situations of objective safety in anxiety patients (Milad et al., 2009). Another core symptom of anxiety disorders, though much less investigated, is the excessive avoidance of situations that trigger the fears. These 'safety behaviors' often interfere with daily life activities and valued goals in life, and they are thought to perpetuate the exaggerated levels of fear by precluding opportunities to learn that the feared situations are actually not dangerous. Surprisingly, experimental research on avoidance behaviors in anxiety patients is virtually non-existent. This experiment modifies the Pavlovian fear conditioning procedure to include avoidance, and explores the behavioral and neural processes of this type of fear regulation in anxiety patients (trans-diagnostically) and healthy individuals.

This research project seeks to acquire a deeper understanding of the complex influences of common factors and specific ingredients in psychotherapy. By using frequent process-outcome measures, it will address individualized mechanisms of change in psychotherapy by assessing both between and within patient change processes, using a wide spectrum of change indicators.

Integrating mental health treatments into the primary care delivered at Community Based Outpatient Clinics(CBOCs) that are geographically accessible to rural Veterans is a major priority for the Department of Veterans Affairs. However, there is no scientific evidence that integrating mental health and primary care is clinically effective at smaller CBOCs that have limited mental health staffing. The goal of this proposed project is to implement a "blended" combination of integrated care models that have been adapted for smaller CBOCs using telemedicine technologies, and evaluate the acceptability and effectiveness of the blended, telemedicine-based, integrated care model. If clinical outcomes are improved compared to usual care, findings will be used to justify and facilitate the implementation of this telemedicine-based integrated care model at smaller CBOCs in order to increase rural Veterans' access to effective mental health treatments.

The aim of this study is to investigate the levels of trauma and mental symptoms (i.e., depression and anxiety) among health workers and public service providers 3 months after (T2) the strict social distancing government initiated non-pharmacological interventions (NPIs) related to the COVID-19 pandemic (T1), in a period of lifted distancing protocols. The study also aims to investigate predictors of trauma-symptoms, by analyzing how predictors measured during the COVID-19 pandemic are associated with change in PTSD symptoms from T1 to T2.

This study will investigate if yoga exercises decrease work-related stress and improve stress adaptation in professional health helpers.

PTSD affects a wide variety of symptoms, some of which have been shown to disrupt family relationships. This study will examine some of the effects on parenting, from the perspective of the parent with PTSD.

Anxiety disorders are common disorders, which pose a major burden to society and the individual. An anxiety disorder may be treated with medication, in particular with antidepressants such as the selective serotonin reuptake inhibitors (SSRIs). However, much of what is known about antidepressants is derived from research in depression rather than anxiety. In recent years, researchers have found that antidepressants are more effective for severely depressed patients than they are for patients with milder symptoms. It is possible that a similar relationship between symptom severity and antidepressant efficacy exists for anxiety disorders, but there is currently little evidence available to answer this question. As antidepressants are frequently prescribed to patients with mild or moderate anxiety, a clear understanding of their effectiveness across the severity range is vital to inform treatment decisions. Therefore, the purpose of this meta-analysis is to examine whether initial symptom severity affects antidepressant efficacy for anxiety disorders.

The objective of this study is to measure the frequency and clinical types of mild cognitive impairment (MCI) or dementia that occur among up to 150 military retirees with and without a history of traumatic brain injury (TBI) among residents of the Armed Forces Retirement Home, Washington D.C. and the Veterans Home of California-Yountville. Investigators will compare the characteristics of dementia in those who have had a prior TBI to the characteristics in those without a history of TBI. It is our hypothesis that the dementia or MCI among those with prior TBI has distinct neuropsychological features that distinguishes it from those with dementia or MCI without a history of TBI.

The main purpose is to show the percentage of patients taking antipsychotics with PTSD by looking at approximately ten year's worth of data from 1994 through 2004. We will also determine the type and dose of antipsychotics the patients received, and to determine how many of those patients had psychotic versus nonpsychotic symptoms. We will be obtaining this data from the VISN 7 Corporate Data Warehouse. We hypothesize that there has been an overall increase in antipsychotic use in patient's with PTSD over the last 10 years.
