Filter by:The aim of this study is to assess the utility of advanced magnetic resonance imaging (MRI) and electroencephalographic (EEG) technologies for predicting functional outcomes in patients with severe traumatic brain injury (TBI).
This project is to evaluate sensitivity and specificity of hyperpolarized 13C-pyruvate as imaging agents of altered cerebral glycolysis and mitochondrial dysfunction and assess pyruvate utilization in mitochondria in Traumatic Brain Injury (TBI) patients.
SMART is an interactive web-based program that will allow youth with mild traumatic brain injuries (mTBI) to monitor their symptoms and receive education on problem-solving and coping strategies. This study will evaluate the effectiveness of SMART as a means of improving symptom-management, coping skills, and general well-being during recovery from mTBI. Half of participants will receive the SMART intervention, while half will receive usual care.
The purpose of this study is to evaluate the antipyretic effect of bromocriptine in critically-ill patients with acute neurologic injury and fever from infectious and non-infectious etiologies.
Some of the most common, persistent, and disabling consequences of traumatic brain injury affect an individual's ability to achieve personal goals. Interventions that strengthen abilities such as being able to concentrate, remember, stay calm and overcome challenges, could have far reaching benefits for Veterans. One challenge in rehabilitation is that response to training can be highly variable, and a better understanding of the neural bases for this variability could inform care. This pilot project will test the clinical behavioral effects of a cognitive skill training intervention and explore to what extent changes in markers of the brain's electrical activity (using the non-invasive technique of electroencephalograms, EEG) can explain differences in responses to skill training.
Traumatic brain injury (TBI) affects 1.7 million people in the United States each year, resulting in 2.5 million emergency department visits, 280,000 hospitalizations, >50,000 deaths, and more than $60 billion in economic cost. TBI also affects >30,000 military personnel annually and almost 8% of veterans who received care between 2001 and 2011. Post-traumatic neurologic outcome depends on the severity of initial injuries and the extent of secondary cerebral damage. Ischemia is the most common and devastating secondary insult. Ischemic brain damage has been identified histologically in ~90% of patients who died following closed head injury, and several studies have associated low cerebral blood flow (CBF) with poor outcome. Specifically, CBF of less than 200 ml/min has been shown to be the critical lower threshold for survival in neurointensive care patients. In addition to intracranial hypertension and cerebral edema, systemic hypotension and reduced cardiac output contribute substantially to posttraumatic cerebral ischemia. Additionally, the carotid artery is the most common site of blunt cerebral vascular injury (BCVI), which may further compromise CBF and cause subsequent death or debilitating stroke. Specifically, high grade internal carotid arterial (ICA) injuries are associated with the highest mortality and stroke rate. The investigators' goal is to develop of a wearable noninvasive, continuous, automated ultrasound sensor to accurately measure extracranial ICA flow volume. In doing so, the investigators aim to enable early detection of CBF compromise, thereby preventing secondary ischemic injuries in TBI patients. To achieve this goal, the investigators plan to first build a prototype wearable ICA ultrasound senor with integrated signal processing platform, then test its accuracy in an in vitro system and healthy human subjects.
This study was conducted in two parts: 1. This first part was designed to determine thiopentone dose requirement for induction of anaesthesia with and without the use of Bispectral Index monitoring - Participant and Care Provider in appropriate study arm blinded. 2. As a secondary outcome, Bispectral index monitoring was used to observe changes in neuronal function in intraoperative period as well as haemodynamic changes intraoperatively - Participant and Care Provider blinded.
In the present study the investigators aim to analyze the performance in a battery of social cognition tests of subjects with traumatic brain injury. On the other hand, the effectiveness of a computerized rehabilitation program designed to improve these deficits will be tested, as well as the relationship between social cognition and executive functioning.
This study will examine the efficacy of an emotion regulation intervention delivered online to individuals with traumatic brain injury (TBI) with deficits in emotion regulation. 104 subjects will be enrolled and will receive 24, 60-minute emotion regulation skills-training sessions twice a week for 12 weeks, delivered online in a group video-conference with 3-5 other participants. Participants will be asked to complete online surveys, lasting approximately 40-50 minutes, every four weeks during the intervention and the 12-week follow-up phase. Attendance and compliance will be tracked, and outcomes will be monitored using online data collection methods.
Every year 1.7 million people sustain a traumatic brain injury (TBI) in the United States and of these, 84 % are considered mild TBI (mTBI). mTBI is common both in civilian and military populations and can be debilitating if symptoms do not resolve after injury. Balance problems are one of the most common complaints after sustaining a mTBI and often prevent individuals from returning to their previous quality of life. However, the investigators currently lack clear guidelines on when to initiate physical therapy rehabilitation and it is unclear if early physical therapy is beneficial. The investigators believe that the underlying problem of imbalance results from damage to parts of the brain responsible for interpreting sensory information for balance control. The investigators hypothesize that retraining the brain early, as opposed to months after injury, to correctly interpret sensory information will improve recovery. The investigators also believe this retraining is limited when rehabilitation exercises are performed incorrectly, and that performance feedback from wearable sensors, can improve balance rehabilitation. There are three objectives of this study: 1) to determine how the timing of rehabilitation affects outcomes after mTBI; 2) to determine if home monitoring of balance exercises using wearable sensors improves outcomes; and 3) to develop a novel feedback system using wearable sensors to provide the physical therapist information, in real-time during training, about quality of head and trunk movements during prescribed exercises. The findings from this research could be very readily adopted into military protocols for post-mTBI care and have the potential to produce better balance rehabilitation and quality of life for mTBI patients and their families.
