Filter by:Vasopressor for current treatment protocols for acute traumatic brain injury can lead to vasoconstriction and thus cerebral hypoperfusion that can be detected with cerebral oxymetry as a drop in SCO2.
In this randomized, controlled clinical trial, we will evaluate the effects of (1) a brain-training program that uses real-time neurofeedback in functional magnetic resonance imaging (fMRI) to allow people to learn how to gain voluntary control over activity in targeted brain regions and/or (2) 8 weeks of computer-based cognitive training using a software program (Cognitive Remediation for Brain Injury (CRBI)) versus control training tasks on cognitive learning and symptoms. In addition, the investigators will measure brain function (active and resting functional magnetic resonance imaging) and structure (high resolution magnetic resonance imaging) before and after treatment.
This study has the objective to determine if intranasal dexmedetomidine, a sedative, is suitable for pediatric sedation in children undergoing tomographic scans.
The purpose of this study is to improve behavior control displayed by persons with traumatic brain injury by assessing effectiveness of treatments for post-TBI irritability and aggression.
Objective: In this study we will develop and apply imaging techniques to perform the first three-dimensional (3-D) measurements of brain biomechanics during mild head movement in healthy human subjects. Biomechanics is the application of mechanics, or the physical principles in action when force is applied to an object, to the anatomical structure and/or function of organisms. Such techniques will be invaluable for building computational models of brain biomechanics, understanding variability of brain biomechanics across individual characteristics, such as age and sex, and determining brain sub-structures at risk for damage when movement of the head is accelerated, such as during a traumatic event. Study Population: Measurements will be performed on 90 healthy men and women aged 18-65. Design: We will build upon the model pioneered by our collaborator, Dr. Philip Bayly. The model places a human subject in a magnetic resonance (MR) scanner with one of two head support units that allows a specific range of motion. Each head support is latched such that it can be released by the subject, and results in either a rotation of the head of approximately 30 degrees or a flexion-extension of the head of approximately 4 degrees. Although both supports are weighted so that the motion is repeatable if the subject is relaxed, the subject can easily counteract the weight. The resulting acceleration/deceleration is small (in the range of normal activities, such as turning one's head during swimming) and has been validated and used in other human investigations of brain biomechanics. The subject repeats the motion multiple times during the MR scan under their own volition and desired pace to measure motion of the head and brain. Outcome measures: This project is a pilot study evaluating the potential of extracting three-dimensional estimates of brain deformation, such as strain measurements, using MR imaging. A primary outcome of this project will be a fast MR acquisition sequence for measuring 3-D brain deformation. The sequence will be evaluated by applying the protocol to human subjects, followed by preliminary quantification of the reproducibility and stability of deformation measurements.
Comparison between a normothermia protocol and current protocol (acetaminophen plus blankets) 1. Normothermia Protocol is successful in achieving and maintaining normal temperature in moderate to severe Traumatic Brain Injury (TBI) patients.(using Arctic Sun for 96 hrs from admission to Neuro ICU) 2. Normothermia is translated into improved neurologic Outcome and survival compared to standard of care (Physician management)
The purpose of this study is to determine whether Prolonged Exposure Therapy (PE)is effective in the treatment of post-traumatic stress symptoms in children and adolescents with mild traumatic brain injury (m-TBI) due to motor vehicle accident.
Prospective, Open Label, Cohort Study in Traumatic Brain Injury Patients. The goal of this study is to assess the safety of NTx®-265. NTx®-265 will be administered over 9 days, and patients will be followed for an additional 6 months.
This study will test if patients with moderate to severe traumatic brain injuries also have endocrine abnormalities, examine any existing relationships among fatigue, depression and endocrine abnormalities, and the relationship between endocrine abnormalities, quality of life, and community integration.
Brain injury from explosive blast is a prominent feature of contemporary combat. Although protective armor and effective acute medical intervention allows soldiers to survive blast events, a growing number of veterans will have disability stemming from blast-related neural damage. Soldiers also return from combat with psychological disabilities caused by traumatic war events. The clinical presentation of individuals with blast-related neural damage and post-traumatic psychopathology are markedly similar and thus a clear description of the direct consequences of explosive blast is complicated by the emotional and cognitive sequelae of psychological trauma. We will use sophisticated measures of neural function and structure to characterize brain injury from explosive blasts in a sample of Operation Iraqi Freedom (OIF) National Guard soldiers who returned from deployment in the fall of 2007. Survey data gathered near the end of deployment indicated that over 50% of the brigade had been exposed to direct physical effects of explosive blasts. To fully characterize the effects of blast on the brain and differentiate them from post-traumatic stress disorder, we will contrast groups of soldiers exposed to blast and with groups experiencing post-traumatic stress disorder. This investigation will improve the characterization of blast-related traumatic brain injury, describe the essential features of the condition in terms of neural function and structure to inform diagnosis, and characterize mechanisms of recovery after blast-related neural injury to allow the creation of interventions that return soldiers to maximum levels of functioning.
