Filter by:Up 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.
The objective of this study is to show that, in patients undergoing carotid endarterectomy, brain damage, assessed by the determination of S100B before removing the clamp, is less severe with a balanced anesthesia consisting of remifentanil combined with Xenon (experimental arm) compared with remifentanil anesthesia associated with propofol (reference arm).
Background: - Previous studies have shown that computer-based devices that simulate everyday tasks can be helpful for evaluation and rehabilitation in people who have had strokes. Researchers are interested in studying whether similar devices can be used to evaluate and treat individuals who have had a traumatic brain injury, to determine if the device should be developed to help with rehabilitation in the future. Objectives: - To evaluate the effectiveness of a computer-based simulation compared with actual performance of actions in individuals who have had a traumatic brain injury. Eligibility: - Individuals at least 18 years of age who have had a non-penetrating mild or moderate traumatic head injury within the past year and have experience playing computer games. Design: - Participants will be screened with a physical and neurological examination and medical history. - Participants will complete questionnaires and an interview about mood and feelings, stress levels, quality of life, and how well they function at work or at home. Participants will also have tests of memory, attention, thinking, and reasoning. Some of the questionnaires and tests will be completed in writing, some orally, and some on a computer. - Participants will have movement and coordination tests that involve simple tasks such as putting pegs in a pegboard, using a key, lifting different objects, and folding things. - Participants will duplicate the movement and coordination tests by using a computer program that simulates the tasks with a cursor on a computer screen. Participants will do four separate simulated tasks (such as arranging letters or hitting a nail with a hammer) three times. - The full visit will take about 4 hours, and no followup visits are required.
The CRASH-3 trial will provide reliable evidence about the effect of tranexamic acid on mortality and disability in patients with traumatic brain injury. The effect of tranexamic acid on the risk of vascular occlusive events and seizures will also be assessed. Additionally, a nested study will be conducted in a subset of CRASH-3 trial participants. This nested study (CRASH-3 Intracranial Bleeding Sub-Study [CRASH-3 IBS]) will examine the effect of tranexamic acid on intracranial haemorrhage and cerebral ischaemia using CT Scans in approximately 1,000 patients randomised into the CRASH-3 trial.
Today's hospitals need innovative solutions to help patients transition from our care to self-management at home. The vast majority of the patients seen in Dodd Rehabilitation Hospital and associated clinics leave our care with persistent and life-altering challenges - behavioral, cognitive, emotional and/or physical. The period of time immediately following discharge is an under-addressed stage within the continuum of care. The investigators are researching solutions to help patients in this transition to self-care and believe that multiplayer gaming paradigms may be a promising innovation to facilitate this transition. The investigators believe that Dr. Jane McGonigal's SuperBetter, and positive play games like it, are promising novel interventions that could make a positive difference in the ability of our patients to successfully transition to self care after discharge from therapeutic care. Specifically, the investigators will evaluate feasibility of use of such a game by mild to moderate brain injured individuals and to record pilot data to help us plan a clinical effectiveness follow up study. Our goal is to finish this study with an intervention tailored for use within the clinical continuum of care and sufficient pilot data to prepare for a randomized clinical control trial of this intervention.
The Armeo Spring has proven its effectiveness in the rehabilitation of acute stroke patients. It neutralizes limb weight, enabling patients to use residual control in both arm and hand and to follow exercises guided by simulations of real-life challenges. The Armeo Spring incorporates wrist pronation and supination, allowing patients to enhance functional reaching patterns. Aim of the study is to compare the Armeo device with standard physiotherapy in chronic patients with acquired brain lesions. The result of the trial should show which treatment is more effective in the clinical practice. A significant better outcome of one arm should suggest to follow one treatment strategy more than the other.
The aim of this study is to determine the effects of an acute session of physical exercise on cognitive functioning and humor of traumatic brain injury patients and to investigate whether different cognitive responses can be achieved with different intensities of exercise (moderate and vigorous). The investigators hypothesize that while moderate intensity physical exercise may be beneficial to cognitive functioning, vigorous intensity may be detrimental to TBI patients, as physical fatigue may impair alertness and other higher cognitive functions.
This 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.
The purpose of this pilot project is to determine whether using one inertial sensor on the waist during routine clinical balance testing (i.e. Balance Error Scoring System (BESS)), will be a more immediate, objective, reliable and sensitive way to measure and quantify balance deficits in individuals with mild Traumatic Brain Injury (mTBI).
Main purpose of the study is to evaluate the effect of sevoflurane on intra cranial pressure (ICP) after traumatic brain injury. Patients admitted for traumatic brain injury equipped with ICP measurement will be sedated with sevoflurane via the Anaconda device during 12 hours. Sedation will be controlled with BIS.
