CONcussion Treatment After Combat Trauma (CONTACT)
Traumatic Brain InjuryThis study compares the effects of Individualized Scheduled Telephone Support (ISTS) and Usual Care (UC) for service members with Mild Traumatic Brain Injury (mTBI). A total of 400 service members will participate in this study. ISTS is a telephone intervention that provides injury-related education, training in problem solving, and focused behavioral strategies for problems (e.g. anxiety, depression) that commonly co-occur with MTBI. ISTS also includes access to usual care and web-based and printed educational material. The 12 phone calls included in ISTS will be administered over a 6-month period. UC is the usual care provided to service members attending the Traumatic Brain Injury (TBI) Clinics at Madigan Army Medical Center and Womack Army Medical Center, plus web-based education and 12 mailings of educational materials over a 6-month period. Subjects will complete major assessments at study entry and then 6 months and 12 months later. The primary aim of the study is to compare the effects of ISTS and UC on post-concussive symptoms and emotional distress at the 6-month assessment. The investigators predict that participants who receive ISTS will report lower levels of post-concussive symptoms and emotional distress at the 6-month assessment. Secondary aims include comparing the longer term effects of ISTS and UC at the 12-month assessment, as well as comparing their effects on other outcomes such as post-traumatic stress symptoms, quality of life, resilience, and work activity.
Neural Markers and Rehabilitation of Executive Functioning in Veterans With Traumatic Brain Injury...
Traumatic Brain InjuryPosttraumatic Stress DisorderUp to half of all military service members with combat-related traumatic brain injury (TBI) also suffer from Posttraumatic Stress Disorder (PTSD). TBI and PTSD are each associated with cognitive problems in what are called 'executive functions' such as planning actions, inhibiting behavior, monitoring one's own thoughts and feelings, and solving problems day-to-day. These types of impairments occur more often among veterans with both TBI and PTSD than among those with only one of these conditions. The combination of TBI and PTSD in veterans has also been linked to problems with anger and violence, which are common complaints of veterans seeking mental health services post-deployment and have been shown to predict poor treatment outcomes in Iraq and Afghanistan veterans. Although the relationship between combined TBI/PTSD diagnoses and post-deployment adjustment problems has been demonstrated, there has been little research into clinical interventions designed to reduce the severity of cognitive and affective symptoms in veterans with both TBI and PTSD. Therefore, the investigators propose a randomized clinical trial involving a cognitive rehabilitation intervention that targets improved executive functioning, with the participation of N=100 veterans diagnosed with both TBI and PTSD (n=50 in experimental group and n=50 comparison). As part of the study, all participants will receive an iPod touch. Participants will be placed into one of the two study groups randomly. Based on which group participants are placed in, they will receive one of two different sets of iPod touch apps and programs that address and aim to improve different facets of cognitive functioning. Regardless of which group, Veterans will be instructed to daily practice iPod touch applications on cognitive functioning. Also, family members will be trained as "mentors" to reinforce use of the applications in everyday living environments. Trained facilitators will also travel to participants' homes to meet with veterans and family to observe behaviors in the home environment, arrive at strategies for applying new skills in their situations, troubleshoot any iPod technical problems, and review family mentoring processes. The investigators will measure clinical outcomes using a comprehensive array of functional and structural methods at baseline and six months. The investigators hypothesize improved executive function among those in the experimental group as well as reduced irritability/impulsivity and improved social/occupational functioning. The investigators further hypothesize that, as a group, veterans participating in the cognitive rehabilitation program will show significant changes in neural activity associated with executive functions when comparing pre- and post-treatment EEG and fMRI responses. Better understanding of the neural circuitry and neurocognitive function underlying executive function and associated affective control deficits in veterans with both TBI and PTSD, and how they relate to treatment outcome, will allow us to better identify therapeutic targets for cognitive rehabilitation. The current proposal aims to explore the relationship between brain function and connectivity in selective pathways/circuits, neuropsychological functioning, and cognitive rehabilitation response in veterans with both TBI and PTSD. This study of the neurobiology and neuropsychology associated with intervention efficacy will allow us to identify veterans with both TBI and PTSD who are predisposed to positive treatment outcomes. To our knowledge, this will be the first attempt to integrate neurobiological and neurocognitive techniques with information about the efficacy of a theoretically and empirically driven cognitive rehabilitation intervention in veterans with combined TBI/PTSD diagnoses. This research may suggest additional avenues for assessment of clinical intervention efficacy and the identification of therapeutic targets (e.g. alteration of function in fronto-limbic circuits) relevant to the military population. Given links between TBI/PTSD, executive dysfunction, and anger, impulsivity, and aggression, efforts to rehabilitate cognitive function will be particularly important to ensure that current and future veterans adjust successfully when they return home to their families, workplaces, and communities.
Effect of Passive Gait Training on the Cortical Activity in Patients With Severe Traumatic Brain...
Craniocerebral TraumaTraumatic Brain Injury1 moreThe aim of this study is to determine whether passive gait training increases arousal, demonstrated as changes in EEG (electroencephalogram) activity. Hypotheses: 1) Passive gait training increases EEG-frequency in patients with impaired consciousness due to severe traumatic brain injury. 2) Passive gait training increases conductivity speed of the cognitive P300-component of ERP in patients with impaired consciousness due to severe traumatic brain injury.
Resuscitative Endocrinology:Single-dose Clinical Uses for Estrogen-Traumatic Brain Injury
Traumatic Brain InjuryEach year in the United States alone, a third of a million persons are hospitalized for traumatic brain injury (TBI), of whom approximately 1/4 die. Most are less than 30 years of age. Not only are the health care costs staggering for both initial care and rehabilitation, but the societal loss in terms of economic impact reaches into the billions of dollars annually in the U.S. alone. Despite advances in neurosurgical interventions and intensive care management, many survivors do not fully recover. A significant cause of this mortality and morbidity is thought due to potentially preventable secondary injury, namely oxidant injury, inflammation, and apoptosis in the penumbra (the area of brain surrounding the primary lesion, which is at-risk, but potentially salvageable), beginning in the first few hours after the severe traumatic event. Despite the current bleak outlook for many of these patients, a series of animal investigations have uncovered a promising solution to the problem of the secondary injury seen in severe TBI and other similar processes, namely the early administration of estrogen, a strong anti-oxidant, anti-inflammatory and anti-apoptotic compound. Based on these encouraging results from animal studies, the investigators hypothesize that early administration of IV Premarin® in patients with severe TBI will safely reduce secondary brain injury, improve neurological outcomes, and improve survival.
Hypothermia in Traumatic Brain Injury in Children (HiTBIC)
Traumatic Brain InjuryThe purpose of this study is: To determine the safety and feasibility of performing an international multi-centre randomized control trial of early and prolonged hypothermia to improve outcome in children with severe traumatic brain injury (TBI). To determine whether in children with severe traumatic brain injury, prolonged initial hypothermia (minimum 72 hours at 32-33 degrees) improves the proportion of good outcomes 12 months after injury when compared to initial normothermia (36-37 degrees).
Improving Executive Functions After Traumatic Brain Injury (TBI): A Clinical Trial of the "Executive...
Traumatic Brain InjuryThis is a randomized clinical trial which compares a standard day treatment program for individuals with TBI with the "Executive Plus" program; the latter emphasizes training of attention, emotional self-regulation and problem solving. The goal of the Executive Plus program is to maximize executive functioning, as well as the long-term outcomes of community participation and satisfaction with daily life.
Treatment of Post-TBI Depression
Traumatic Brain InjuryDepressionRandomized clinical trial that compares the effects of cognitive behavioral therapy (CBT) and supportive psychotherapy for depression. Short- and long-term outcomes will be evaluated in terms of changes in mood (primarily depression and anxiety), participation in activities and life satisfaction.
Safety of Autologous Stem Cell Treatment for Traumatic Brain Injury in Children
Traumatic Brain InjuryThe purpose of this study is to determine if bone marrow progenitor cell (BMPC) autologous transplantation in children after isolated traumatic brain injury is safe and will improve functional outcome.
Dexanabinol in Severe Traumatic Brain Injury
Traumatic Brain InjuryEach year a large number of patients are hospitalized at Shock Trauma Centers with severe head injuries. Bleeding into and swelling of these patients' brains may cause compression of vital structures, disability and death. Sometimes surgery is needed. Unfortunately, the investigators have no medication to treat the bad effects of head trauma. Part of the brain damage is due to toxic chemicals (including one called glutamate) that are released by the damaged nerves. Dexanabinol may prevent some of the bad effects of glutamate on the brain and may protect the brain against uncontrollable swelling and death.
