Filter by:The goal of this study is to look at how a type of drug called cannabinoids are related to the processing of fear signals, the experience of emotions and fear, and the pattern of activity in the brain that is involved in these processes and how this relates to the development of post-traumatic stress disorder (PTSD). PTSD is an anxiety disorder that occurs after experiencing a traumatic event(s) and is characterized by unwanted memories of the trauma(s) through flashbacks or nightmares, avoidance of situations that remind the person of the event, difficulty experiencing emotions, loss of interest in activities the person used to enjoy, and increased arousal, such as difficulty falling asleep or staying asleep, anger and hypervigilance. The information gained from this study could lead to the development of new treatments for persons who suffer from anxiety or fear-based disorders.
The proposed study builds upon preliminary studies in self-selected populations to identify opportunities for early identification of World Trade Center-related health consequences in adolescents. If adverse health consequences are identified, proactive cardiometabolic and pulmonary screening of exposed children may be indicated, with targeted interventions intended to prevent development of chronic obstructive pulmonary disease, and adverse cardiometabolic outcomes in adulthood.
The main objective of the study is to test the feasibility of the ICU diaries intervention in the ICU. The investigators do not have sufficient power to detect differences in the hypotheses below, but will use the present pilot study to inform sample size required to adequately power a follow-up randomized control trial. (1) The investigators hypothesize that subjects exposed to a psychoeducation condition will have reduced rates of post-traumatic stress disorder (PTSD) compared to those experiencing treatment as usual (TAU). (2) The investigators hypothesize that compared to participants in the psychoeducation and TAU groups, those subjects exposed to an ICU diary, and those exposed to both ICU diary + psychoeducation conditions, will have significantly reduced rates of PTSD at follow-up. (3)The investigators hypothesize that participants exposed to the ICU diary + psychoeducation condition will have significantly lower rates of PTSD compared to those in the ICU diary alone condition.
This project addresses the rehabilitation and mental health needs of married combat Veterans post-deployed from Iraq or Afghanistan with a mild traumatic brain injury (mTBI) and/or significant posttraumatic stress (PTS) or combat-related stress (CS) by providing psychoeducation, communication and problem solving skills in a multifamily group (MFG) setting. In this group, Veterans and spouses/cohabiting partners learn customized therapeutic strategies to help compensate for deficits and promote Veteran community integration, interpersonal and emotion regulation skills, and marital satisfaction. The effectiveness of the skills-based MFG will be compared to that of a health education group which offers a supportive environment and basic education without skills training through a randomized clinical trial. As there is currently no family-based intervention for Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans with mTBI offered within the VA spectrum of services, this intervention fills a crucial gap in healthcare for our newest Veterans.
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.
The study has two goals. First to develop a computer-based intervention meant to alter cognitive biases that contribute to ongoing PTSD symptoms. Second, we sought to pilot test the intervention in a small sample of veterans for feasibility and acceptability.
Through many years, the standard care has been to use continuous sedation of critically ill patients during mechanical ventilation. However, preliminary randomised clinical trials indicate that it is beneficial to reduce the sedation level in these patients. The NONSEDA trial is an investigator-initiated, randomised, clinical, parallel-group, multinational, superiority trial designed to include 700 patients from at least six ICUs in Denmark, Norway and Sweden, comparing no sedation with sedation and a daily wake-up trial during mechanical ventilation. This is a substudy of the NONSEDA trial, concerning 250 patients included at trialsite Kolding, Denmark. The aim of the substudy is to assess the effects of no sedation on posttraumatic stress disorder after discharge from ICU. Our hypothesis is that critically ill patients who are not sedated during mechanical ventilation will have less posttraumatic stress disorder after discharge.
Service Dogs are trained to assist people with disabilities to accomplish tasks which permit the individual to be more functional in their home and social environment. Often the dogs are trained to help in the completion of activities of daily living and instrumental activities of daily living. Service Dogs are efficacious for individuals with disabilities, such as vision limitations, spinal cord injury and hearing problems. In addition, some mental health outcomes have improved with the introduction of a Service Dog. A research study was mandated in the Department of Defense Bill of 2010, to examine the efficacy of service dogs for Veterans with Post Traumatic Stress Disorder (PTSD). Together with the Cooperative Studies Program, the proponents have designed a research study to effectively meet the demands of the Bill and to provide timely research into an evolving field.
This observational study follows subjects who have been exposed to a traumatic event and are at risk of developing PTSD symptoms. Participants are recruited within six hours of a traumatic event, and, starting from the recruitment session, are then examined on six set points of time within a period of thirteen months. The examinations include both biological studies of cortisol in hair, blood and saliva, and psychological examinations and questionaires that assess the development and severity of PTSD symptoms. The novel method of sampling hair cortisol allows investigators to retroactively estimate the mean levels of blood cortisol during the tree months prior to the sampling. The study aims at further illuminating the correlation between cortisol levels both prior and following a traumatic event, and the development and severity of PTSD symptoms
This is a prospective cohort treatment intervention study (n=200) whereby U.S. service members and veterans with symptoms of PTSD will undergo 2-5 sessions of ART delivered by Florida licensed mental health professionals trained in ART. The 3 study aims are to: (i) evaluate among U.S. service members and veterans overall, and within specific subgroups, the magnitude of change in symptoms of PTSD following treatment with ART; (ii) evaluate the sustainability of treatment response with ART; and (iii) evaluate the cost effectiveness of ART compared to prolonged exposure (PE) therapy in the treatment of symptoms of PTSD.
