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

The project utilize experience and knowledge gained from previous early childhood projects in NYC post 9/11 and Sderot. The overall goals are: Identifying young children (under 6 years old) and their parents who are suffering from posttraumatic distress in the aftermath of the continuing conflict on Gaza border, Israel. Increasing the capacity of local institutions to treat toddlers and families at risk. Providing resilience -building services that strengthen the coping abilities of families and caregivers in response to continual terrorism.

Posttraumatic stress disorder (PTSD) occurs in response to an extreme traumatic stressor. It is estimated that as many as 1 million VA patients who were exposed to combat may have PTSD. VA patients with PTSD recently have been designated as a �Special Emphasis� population for which health care resources are allocated at approximately 14 times those allocated to patients without such chronic, complex, and intensive health care needs (i.e., �Basic Care� groups). Despite recognition of its substantial impact upon VA resources, the extent and means by which PTSD affects health and health care use remain unclear. This study seeks to enhance understanding of both the extent and means by which PTSD affects the health and the health care use of patients in VA ambulatory care. To meet this goal, we build on an ongoing HSR&D project, the Veterans Health Study (VHS), a prospective longitudinal study of 2,425 VA ambulatory care patients.

Aim: To identify, assess, and address organizational context and provider-level barriers and facilitators of implementation of Evidence-based treatments (EBTs) using a mixed-methods approach in a diverse community mental health center (CMHC), Massachusetts General Hospital Chelsea Health Clinic (MGH Chelsea). Hypothesis: Anticipated barriers may include, but are not limited to, organizational climate, heavy case-loads, community mental health workers (CMHW) beliefs about EBTs, and provider motivation to learn EBT.

The purpose of this project is to develop an intervention to improve psychosocial functioning and quality of life for older Veterans with partial or full PTSD.

This is a multicenter retrospective study to investigate the dosage regimens of sertraline in the treatment of Posttraumatic Stress Disorder (PTSD) under current medical practice and the efficacy and safety of this drug in patients with PTSD. Data will be collected from the medical records of patients with PTSD.

Traumatic brain injury (TBI) and post traumatic stress disorder (PTSD) are common combat related problems and may be associated with a greater risk of Alzheimer's disease (AD). The purpose of this study is to examine the possible connections between TBI and PTSD, and the signs and symptoms of AD on Veterans as they age. The information collected will help to learn more about how these injuries may affect Veterans of the Vietnam War as they grow older, as well as Veterans of the current wars in Iraq and Afghanistan, who also have these types of combat related injuries.

This is a study investigating immune function and relationships to the hypothalamic-pituitary-adrenal (HPA) axis in Post-traumatic stress disorder (PTSD) compared to controls without PTSD. The study involves 99 adult veterans and civilian subjects over a 3 year period. The study involves measuring immune and neuroendocrine parameters from blood samples obtained before and after a dexamethasone suppression test. The aim of the study is to determine whether immune alterations exist in PTSD and whether the immune-HPA axis interactions in this disorder are different from non-PTSD subjects with the future aim of studying whether immune dysregulation in PTSD may be linked to the increased risk for medical and psychiatric comorbidity in this population.

The purpose of this study is to examine differences in post-concussive (PC) symptom endorsement among four groups of Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF) Veterans: those with a history of target, service-related, mild traumatic brain injury (mTBI) and co-occurring posttraumatic stress disorder (PTSD) (Group 1); those with a history of target, service-related, mTBI only (Group 2); those with PTSD only (Group 3); and those with no history of target, service-related, mTBI or PTSD (Group 4) by examining scores on the Neurobehavioral Symptom Inventory (NSI). Support for this study is provided by previous research highlighting the complex relationship between mTBI, PTSD and subsequent PC symptom endorsement (Brenner et al. 2010; Terrio et al, 2009). HYPOTHESES ARE AS FOLLOWS: Individuals with a history of target, service-related, mTBI only (Group 2) and individuals with PTSD only (Group 3) each will report significantly more PC symptoms, as measured by NSI total scores, when compared to those with no history of service-related mTBI or PTSD (Group 4). Individuals with co-occurring target, service-related, mTBI history and PTSD (Group 1) will report significantly more PC symptoms, as measured by total NSI scores, than either those with target, service-related, mTBI only (Group 2) or those with PTSD only (Group 3).

The aim of the project is to advance our understanding of how individuals with Posttraumatic Stress Disorder (PTSD) experience symptoms in their every-day lives when they are in their home environment. To date, all PTSD assessments are retrospective; individuals with PTSD are asked to recount and report their symptoms over the past weeks or months. Such assessment procedures are negatively impacted by individuals' abilities to accurately recall information. Moreover, retrospective assessments provide little information about how symptoms are experienced in the moment and how these experiences then lead to other behaviors. The proposed project addresses these limitations by assessing PTSD symptoms and associated biological markers (e.g., sleep, heart rate, heart rate variability) in real-time by asking subjects to wear a smart device and complete brief surveys. Data will be collected from 50 individuals with PTSD and 20 healthy controls to help us better understand individuals' real-time experience with PTSD and lay the foundation to develop algorithms for possible in-the-moment interventions in the future.

Mild brain injury or concussion affects about four million Americans each year. Some people recover completely while others, especially those with multiple concussions, develop chronic headaches, neurodegenerative diseases and psychiatric disorders. One of the reasons that concussion is difficult to treat is that it is difficult to detect. Radiographic studies such as CT (computed tomography scan) are by definition unrevealing of structural injury in concussed patients. Some MRI (magnetic resonance imaging) sequences may be useful adjuncts in the diagnosis of concussion but even these are not consistently present in all patients with symptoms. Clinical tests for concussion often require baseline studies, and thus are generally reserved for athletes and others at highest risk for concussion. The investigators have developed a novel eye movement tracking algorithm performed while subjects watch television or a music video that determines whether the eyes are moving together (conjugate) or are subtly not together (disconjugate). The investigators preliminary data shows that people with lesions in their brain or recovering from brain injury have disconjugate gaze that is not detectable by ophthalmologic examination but is detected by our algorithm.
