Active clinical trials for "Stress Disorders, Traumatic"

The COVID-19 pandemic is a traumatic event which could lead to a greater risk of developing post-traumatic stress disorder, especially in cancer patients who feel more at risk of contracting the virus, and fear developing serious symptoms. The study's primary objective is to measure the presence of a potential post-traumatic stress disorder in cancer patients, and to assess the associated factors. The secondary objectives are to measure patients' anxiety, as well as their perception of both the management of their cancer care, and their fear of a cancer recurrence. It is a prospective, multi-centric study using self-assessing survey offered to cancer patients currently under ongoing care or treatment. The surveys will be sent by post at the beginning of the study, and again 6 months later. Expecting a participation rate of 40%, 4000 patients will be contacted, over a period of 3 months, in order to receive 1600 responses, and 640 responses 6 months later. Researching the factors associated with the appearance of post-traumatic stress could lead to better screening of patient disorders in highly anxiety-provoking crisis situations. As a result, it would lead to an improvement of their care, healthcare organization, and their follow-up in the case of a new epidemic or any other stressful event of this magnitude. Furthermore, promoting the patient's expression capabilities favors their implication in their care, and facilitates the development of health democracy.

Introduction: Coronavirus disease 2019 (COVID-19) is a new pathology, declared a public health emergency by the World Health Organization, which can have negative consequences for pregnant women and their newborns. It is estimated that 1 in 5 women will develop a mental illness in the perinatal period. COVID-19 pandemic has been associated with anxiety and depression in the population. The current pandemic is a unique stressor with potentially wide-ranging consequences in the perinatal period, but little is known about the impact of COVID-19 on perinatal mental health. Thus, the objective of this study is to explore the experiences of pregnant and new mothers during the current pandemic, particularly its impact on perinatal mental health (including depression, anxiety, PTSD and psychological distress). Methods: The study design is a prospective observational study, with a baseline assessment and three follow-ups: one month; three months; and six months post baseline. This international study will be carried out in 11 European countries (Albania, Bulgaria, Cyprus, France, Greece, Israel, Malta, Portugal, Spain, Turkey, United Kingdom) Chile and Brazil. The study population will comprise pregnant women and new mothers with an infant under six months of age, covering a broad range of women across the perinatal period. Ethics and dissemination: The study and handling of the data will follow all national required data protection standards. Each researcher (or team of researchers) involved will submit the project to their local ethical committee before starting the project. Results from the project will be disseminated in peer reviewed journals and international conferences.

Background: A traumatic brain injury (TBI) could mean a person is at high risk for other long-lasting problems. These problems could include post-traumatic stress disorder (PTSD), depression, and post-concussive syndrome (PCS). For example, about 700,000 Americans each year who have a TBI later go on to have PTSD also. Depression and PCS are also common in people who had a TBI. Some people will have these problems later. These problems can seriously interfere with a person s life. Some people will not have these problems at all. There are many reasons for this difference. Researchers think the main reason is that people have different genetic and environmental influences. Right now, we only have few kinds of treatments to prevent or treat these problems after a TBI. The few treatments we have often do not work well. It is important to understand what factors make a person at high risk for these problems after a TBI. This could allow researchers and doctors to help address these problems early. Addressing these problems earlier may help a person have better health in the long run. Objectives: To study the biological changes that happen after mild to moderate TBI which could be linked to the onset of PTSD, depression, and post-concussive syndrome To study brain mechanisms that could explain risks for getting a psychiatric disorder after mild to moderate TBI. This will be done using a test called functional MRI (fMRI). This test takes images of the brain while a person is doing a simple task. Eligibility: Men and women who are 18 to 65 years old. Had a mild to moderate TBI (including concussion) in the last month. Design: 5 outpatient visits to the NIH Clinical Center over one year. The first visit is a screening visit to see if you can join the study. This visit must happen within 30 days of the TBI. The visit includes lab work (blood and urine), a history and physical exam done by a physician or nurse practitioner, and a psychiatric interview with a behavioral health nurse. Visits 2, 3, 4 and 5 happen at one, three, six and twelve months post-injury. At these visits participants may have some or all of the following tests: blood and saliva collection, urine collection, questionnaires and interviews to assess symptoms, a test to see your response to stress (called hydrocortisone challenge), and fMRI brain imaging. This study does not provide treatment. This study is not a substitute for seeing a primary care provider. This study should not replace any therapies you may be taking.

This study looks at the biological effect of domestic violence and abuse (DVA) on women's mental health. The mechanisms through which DVA causes mental disorders are very poorly understood. Similar to other demands, DVA activates the biological stress system, of which the chief component is the hypothalamic-pituitary-adrenal (HPA) axis, which produces chemical cortisol. Cortisol levels increase in response to short-term demand and help organisms deal with it by changing the processes of getting energy from food and also mental function. However constant activation of the HPA axis can cause damage and accelerate disease. This study tests the hypothesis that compared to non-abused women all abuse victims have altered diurnal rhythm in cortisol secretion and that the pattern of this alteration is predicted by abuse characteristics, such as its type, severity, duration, and cessation. To examine the hypothesis the following research questions will be addressed: 1) whether cortisol levels are related to mental health state; 2) whether cortisol levels are related to type, severity, duration and cessation of DVA; 3) whether there is any difference in cortisol concentrations between those women exposed to both childhood abuse and DVA and those who have experienced only the latter; 4) whether cortisol levels vary between women, living in refuge and those not living in refuge? To answer these research questions 214 women will be recruited in a domestic violence agency. Baseline and 3-monthly follow-up measures will be taken over 6 months after recruitment. Women will be asked to fill in a questionnaire to evaluate their demographics, health, experience of childhood abuse and DVA. Women's weight and height will be taken. In addition participants will be asked to take three saliva samples: 1st in the evening in bed, 2nd - next morning immediately upon awakening, and the 3rd - in thirty minutes after awakening. Saliva will be collected by chewing (for 2 minutes) the cotton pledget provided with plastic tube and returned by post or via collection by the researcher. Then the saliva samples will be tested for cortisol and cortisone. Results of the study will increase our understanding of the biological mechanisms of DVA impact on a woman's health and tell researchers and practitioners about the possibility of using cortisol as an indicator to diagnose abuse-related health problems and assess effectiveness of medical care for abuse survivors.

Identifying neural mechanisms of posttraumatic stress disorder (PTSD) treatment could help elucidate reasons for variable treatment response and identify novel treatment targets. Exposure-based therapies have been associated with decreased amygdala and increased cingulate cortex response during emotional processing. The current study examined whether cognitive therapy for PTSD in women reduces activation in insula and amygdala and enhances activation in prefrontal regions during emotional anticipation and pre-treatment prefrontal activation predicts treatment response.

The investigators are seeking people who have been exposed to a traumatic event in the past and have symptoms of posttraumatic stress disorder (PTSD) currently. A person with PTSD may feel significant distress when reminded of a traumatic event or feel depressed, anxious or jumpy. As a part of this study, participants will receive brain MRIs and office assessments before and after psychotherapy. The investigators provide the gold-standard psychotherapy for PTSD, "Prolonged Exposure", free of charge; additionally participants are compensated for their time during assessment procedures. This study is exploring the brain circuitry involved in improvement in response to psychotherapy.

We hypothesize that prevention of Sleep Disordered Breathing among PTSD patients with nasal CPAP will result improve their anxiety, insomnia and alcohol craving (among those who use alcohol to control their symptoms).

This project assesses the usability and feasibility of a multi-behavioral computerized, tailored intervention (CTI) or expert system delivered via the Internet for veterans with Post-Traumatic Stress symptoms. Three behavioral health risk factors, (1) smoking, (2) depression, and (3) stress, that are associated with Post-Traumatic Stress Disorder (PTSD), are included in the Computerized, Tailored Intervention (CTI) system. The project adapts and modifies an existing CTI system built on the Transtheoretical Model of Behavior Change (TTM) to make it relevant to a veteran population. The system has been successfully utilized with general adult populations. The study utilizes methods that are characteristic of a product development project. Each of the four project phases are sequential and build upon the results of the previous phase. Phase 1 focuses on the review of current CTI programs on smoking cessation, stress management, and depression prevention, and integrating them into a multi-behavioral program for application with veterans. Phase 2 includes the development and adaptation of text-based feedback messages and multimedia components for smoking cessation, stress management, and depression prevention for veterans. Initial testing of the modified CTI programs commences in Phase 3. Cognitive and usability testing with veterans are performed, and additional modifications to the behavioral modules are made based on the test results. Phase 4 focuses on a feasibility study to test the multi-behavioral CTI system with veterans online.

Posttraumatic stress disorder (PTSD) is a common and debilitating neuropsychiatric disorder in which an acute fear response to a traumatic event does not abate. This failure to recover from trauma is thought to be due at least in part to a deficit in learning not to fear situations and stimuli previously associated with the trauma (i.e., specifically due to a failure of extinction recall). Pavlovian fear conditioning can be simulated and measured experimentally in humans using a 2-day fear conditioning paradigm developed by our group, wherein conditioning and extinction learning phases are conducted on Day 1, and extinction recall is tested on Day 2. Recent functional magnetic resonance imaging (fMRI) evidence indicates that PTSD is associated with hyper-responsivity of the insular cortex and hyporesponsivity of the ventromedial prefrontal cortex (VMPFC) during exposure to fear-inducing stimuli, consistent with altered excitability of brain regions mediating fear conditioning and extinction. As the brain's principal inhibitory neurotransmitter, GABA exerts a prominent role in modulating neuronal excitability. Interestingly, there are reports that adjunctive treatment with GABA-enhancing antiepileptics is efficacious in PTSD. There is also evidence, albeit inconsistent, that lower serum GABA levels predict a more chronic course of the illness. However, it is unclear whether serum levels accurately reflect brain GABA, which may contribute to inconsistency of serum findings. Moreover, it is possible that GABA alterations may vary in their presence, nature and significance across brain regions implicated in PTSD. The proposed study will examine the relationship of PTSD symptoms and behavioral fear conditioning deficits with regional brain gamma-aminobutyric acid (GABA) using proton magnetic resonance spectroscopy (1H-MRS). We have the following aims and hypotheses: To determine whether GABA alterations are associated with the categorical diagnosis of PTSD and not merely exposure to trauma. It is hypothesized that PTSD will be associated with higher GABA in VMPFC and lower GABA in the right insula. To determine whether GABA levels are significantly associated with dimensional measures of PTSD symptom severity and individual symptom dimensions. It is predicted that higher GABA in the VMPFC and lower GABA in the right anterior insula will be associated with greater total symptom severity. To determine whether GABA in VMPFC and right anterior insula are significantly associated with measures of extinction recall failure and anxiety sensitivity in PTSD. It is hypothesized that VMPFC GABA will be positively correlated with skin conductance response to a conditioned stimulus that had previously been extinguished and insula GABA will be negatively correlated with anxiety sensitivity.

Post traumatic stress disorder (PTSD) has emerged as a significant problem among troops returning from combat zones. A majority of these veterans will report difficulty maintaining or initiating sleep. The purpose of this research will be to conduct a prospective, randomized, wait list controlled, small scale feasibility study to examine if the use of an auricular acupuncture regimen improves quality of sleep for Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF)veterans with PTSD receiving standard PTSD treatment. Hypothesis: Objective and subjective sleep disturbances and sleep quality will be improved in OIF/OEF veterans who receive auricular acupuncture in conjunction with standard PTSD therapy or standard therapy alone.
