Transcranial Electrical Stimulation for mTBI
Mild Traumatic Brain Injury (mTBI)Post-traumatic Stress DisorderMild traumatic brain injury (mTBI) is a leading cause of sustained physical, cognitive, emotional, and behavioral deficits in OEF/OIF/OND Veterans and the general public. However, the underlying pathophysiology is not completely understood, and there are few effective treatments for post-concussive symptoms (PCS). In addition, there are substantial overlaps between PCS and post-traumatic stress disorder (PTSD) symptoms in mTBI. IASIS is among a class of passive neurofeedback treatments that combine low-intensity pulses for transcranial electrical stimulation (LIP-tES) with electroencephalography (EEG) monitoring. Nexalin is another tES technique , with FDA approvals for treating insomnia, depression, and anxiety. LIP-tES techniques have shown promising results in alleviating PCS individuals with TBI. However, the neural mechanisms underlying the effects of LIP-tES treatment in TBI are unknown, owing to the dearth of neuroimaging investigations of this therapeutic intervention. Conventional neuroimaging techniques such as MRI and CT have limited sensitivity in detecting physiological abnormalities caused by mTBI, or in assessing the efficacy of mTBI treatments. In acute and chronic phases, CT and MRI are typically negative even in mTBI patients with persistent PCS. In contrast, evidence is mounting in support of resting-state magnetoencephalography (rs-MEG) slow-wave source imaging (delta-band, 1-4 Hz) as a marker for neuronal abnormalities in mTBI. The primary goal of the present application is to use rs-MEG to identify the neural underpinnings of behavioral changes associated with IASIS treatment in Veterans with mTBI. Using a double-blind placebo controlled design, the investigators will study changes in abnormal MEG slow-waves before and after IASIS treatment (relative to a 'sham' treatment group) in Veterans with mTBI. For a subset of participants who may have remaining TBI symptoms at the end of all IASIS treatment sessions, MEG slow-wave changes will be recorded before and after additional Nexalin treatment. In addition, the investigators will examine treatment-related changes in PCS, PTSD symptoms, neuropsychological test performances, and their association with changes in MEG slow-waves. The investigators for the first time will address a fundamental question about the mechanism of slow-waves in brain injury, namely whether slow-wave generation in wakefulness is merely a negative consequence of neuronal injury or if it is a signature of ongoing neuronal rearrangement and healing that occurs at the site of the injury. Specific Aim 1 will detect the loci of injury in Veterans with mTBI and assess the mechanisms underlying functional neuroimaging changes related to IASIS treatment, and for a subset of Veterans with remaining symptoms, additional Nexalin treatment, using rs-MEG slow-wave source imaging. The investigators hypothesize that MEG slow-wave source imaging will show significantly higher sensitivity than conventional MRI in identifying the loci of injury on a single-subject basis. The investigators also hypothesize that in wakefulness, slow-wave generation is a signature of ongoing neural rearrangement / healing, rather than a negative consequence of neuronal injury. Furthermore, the investigators hypothesize IASIS will ultimately reduce abnormal MEG slow-wave generation in mTBI by the end of the treatment course, owing to the accomplishment of neural rearrangement / healing. Specific Aim 2 will examine treatment-related changes in PCS and PTSD symptoms in Veterans with mTBI. The investigators hypothesize that compared with the sham group, mTBI Veterans in the IASIS treatment group will show significantly greater decreases in PCS and PTSD symptoms between baseline and post-treatment assessments. Specific Aim 3 will study the relationship among IASIS treatment-related changes in rs-MEG slow-wave imaging, PCS, and neuropsychological measures in Veterans with mTBI. The investigators hypothesize that Reduced MEG slow-wave generation will correlate with reduced total PCS score, individual PCS scores (e.g., sleep disturbance, post-traumatic headache, photophobia, and memory problem symptoms), and improved neuropsychological exam scores between post-IASIS and baseline exams. The success of the proposed research will for the first time confirm that facilitation of slow-wave generation in wakefulness leads to significant therapeutic benefits in mTBI, including an ultimate reduction of abnormal slow-waves accompanied by an improvement in PCS and cognitive functioning.

Video NET With CYP Who Witnessed Domestic Violence
Post-Traumatic Stress Disorder in ChildrenPost-Traumatic Stress Disorder in Adolescence5 moreResearch suggests that children and young people (CYP) who witness domestic violence are susceptible to develop Post-traumatic stress (PTS). As their traumatic experiences are often repeated and prolonged, these CYP are likely to present with 'complex trauma' presentations, which also include other difficulties such as depressive symptoms and problems in functioning. This study aims to investigate whether Narrative Exposure Therapy (NET) delivered via videoconferencing can be effective, feasible, and acceptable for CYP who witnessed domestic violence. NET is a brief, evidence-based intervention for complex trauma which has been adapted for CYP. The study will use a 'single case study series' design and look at whether NET can impact on PTS, psychological distress, and functioning. It will also look at the processes of change within NET and participants' experience of the therapy. Young people aged 12-17 who are experiencing PTS after exposure to domestic violence will be recruited from the waiting lists of Child and Adolescent Mental Health Services in Lincolnshire Partnership NHS Foundation Trust and Nottinghamshire Healthcare NHS Foundation Trust. Up to six participants will receive six to ten weekly video sessions and the changes in the outcomes will be explored before, during and after NET. Finally, participants will be interviewed about their experiences. The study is part of a Doctorate in Clinical Psychology programme and funded by Health Education England. Potential benefits include investigating NET with a new group, contributing to the research on complex trauma interventions for CYP, and providing insights on the effectiveness and acceptability of therapies via video.

Emotional Regulation in People With Co-occurring Posttraumatic Stress Disorder and Substance Use...
Posttraumatic Stress DisorderSubstance Use Disorders1 moreThe aim of this project is to look at emotional regulation in people with posttraumatic stress disorder (PTSD) and substance use disorder (SUD). This study will explore how people with PTSD-SUD regulate their emotions and how this might explain the relationship between these two disorders. In turn, this may inform effective treatment strategies for people with comorbid PTSD-SUD. Emotional regulation refers to the way in which people process and respond to their emotions. PTSD and SUD commonly cooccur and this is associated with adverse outcomes including high rates of relapse, overdose, and suicide. We therefore need effective treatments to address this clinical concern. Evidence suggests emotional regulation might be important in the development and maintenance of PTSD and SUD and therefore it might be a useful target for treatment. However, most research in this area has been quantitative and has not considered how gender, social circumstances and trauma or substance type might affect the way people regulate their emotions. This study will recruit 40 adults with trauma histories and PTSD who are currently receiving treatment in a community drug and alcohol service for their substance use. Participants will be interviewed to explore how they regulate their emotions and how this relates to their social circumstances. This study will also explore whether gender, substance or trauma type affect the way people regulate their emotions. We hope this will help to improve treatment for people with PTSD and SUD.

Short-Term Exposure for PTSD
Chronic Post-Traumatic Stress DisorderMarijuana AbuseThis study examines how marijuana use affects processes related to recovery from chronic posttraumatic stress disorder (PTSD). Half the participants will be individuals with chronic PTSD and heavy marijuana use and half will be individuals with chronic PTSD and no marijuana use. This study will assess how individuals with PTSD with heavy or no marijuana use perform on a discriminative conditioning and extinction paradigm designed to measure fear extinction learning, and how they respond to a brief daily imaginal exposure treatment in regards to PTSD symptom reduction.

Improving Mind/Body Health and Functioning With Integrative Exercise
Stress DisordersPost-TraumaticThere is evidence demonstrating that aerobic exercise improves many symptoms of Posttraumatic Stress Disorder (PTSD) including; anxiety, depression, insomnia, and cognition. With the goal of using exercise as a rehabilitation therapy for Veterans with PTSD, a team of scientists and doctors developed a 12-week exercise program, combining aerobic and strength training with concentration training and mindful breathing techniques. The initial pilot study suggested that Integrative Exercise may improve overall quality of life, sleep quality, cardiovascular fitness, and PTSD symptoms. This new study will help determine the effectiveness of Integrative Exercise compared to health education classes. The overall goal is to determine if integrative exercise is an effective rehabilitation intervention for combat Veterans with PTSD.

Cognitive-behavioral Therapy for Treatment of Post-traumatic Stress Disorder and Related Problems...
PTSDThe purpose of this study is to evaluate the efficacy of a form of cognitive behavioral therapy (CBT) in a population of individuals with PTSD and common related problems (depression, anxiety or sleep disorders, pain, psychosocial stressors, low social support, substance use disorder). Half of the participants will receive a cognitive behavioral therapy with specific modules for the treatment of related problems (CBT-E) and the other half of participants will receive therapy without specific modules (CBT-C). The main assumption is that participants treated in the CBT-E condition will present a lower level of symptom intensity of PTSD and a higher remission rate than those in the CBT-C condition during the post-treatment assessment. As a secondary objective, an analysis of the different parameters of effectiveness of the two forms of CBT (e.g., average number of sessions required to reach remission, treatment strategies used) will be performed.

Efficacy of Prazosin in Preventing Post-traumatic Stress Disorder
Acute Stress DisorderAfter a traumatic event such as an accident or an assault, victims may experience intense stress symptoms that may evolve into "post-traumatic stress disorder" (PTSD). It is a frequent and serious pathology, which can be complicated by depression, addiction or suicide. Few means are available to prevent PTSD in people who have just undergone trauma. Prazosin is an antihypertensive drug that blocks α1 adrenaline receptors which could help to stop the vicious circle of stress and prevent the development of the disease. The objective of this study is to demonstrate the efficacy of prazosin to prevent PTSD in patients who visit an emergency department after trauma.
