Filter by:Abnormalities in structural and functional connectivity between brain regions have been suggested as putative biomarkers of mild traumatic brain injury (TBI) and significant contributors to neuropsychological functioning and injury outcome. The purpose of this study is to use two advanced magnetic resonance imaging (MRI) techniques called diffusion-weighted imaging (DWI) and resting state functional MRI to compare structural and functional connectivity between individuals with documented mild TBI and healthy controls. To evaluate the significance of structural and functional connectivity for behavior, the brain imaging data will then be related to measures of cognition and emotion. Over a 4-year period, 150 adults with documented mild TBI and 30 healthy controls will participate in the study. The study will investigate the following questions and hypotheses: 1. Evaluate the DWI metric fractional anisotropy (FA) as a measure of white matter integrity across multiple stages of recovery following mild TBI relative to healthy controls. It is hypothesized that mild TBI will be associated with greater white matter abnormalities than healthy controls. 2. It is hypothesized that there will be a relationship between FA, cognition and emotion as a function of the injury. 3. It is hypothesized that functional connectivity will be related to FA.
The goal of this project is to develop a test to assess frontal lobe function using a rapid, inexpensive, objective, and standardized method, without the need for expertise in cognitive test administration. Such methods would be particularly helpful in traumatic brain injury (TBI), where objective measures are needed, and would greatly expand the capacity to make such assessments in clinical practice and research.
The purpose of this study is to evaluate the effectivenes of a home-based physical therapy program designed to improve balance following traumatic brain injury by incorporating the use of a virtual reality system.
The goal of this project is to determine if it is possible to assess Cerebrovascular Reactivity (CVR) to hypercapnia with functional Near Infrared Spectroscopy (fNIRS). Such a method would be particularly helpful in traumatic brain injury (TBI), where objective measures are needed, and would greatly expand the capacity to make such assessments in standard clinical practice.
This study seeks to compare two different behavioral treatments for pain in Veterans with a history of TBI. Both treatments involve educating the Veteran about pain, discussing the impact of pain, and different ways to manage it in hopes of decreasing pain and its impact on life. These approaches are called "self-management" approaches to pain. Both of these treatments are commonly used in pain clinics to treat pain in persons with back pain, headaches, and other types of chronic pain. The investigators will be delivering both treatments over the telephone to make the treatments accessible to Veterans wherever they live.
The aims of this study explore the relationships between cerebral vasospasm, apolipoprotein-E (apo-E) genotype, physiologic symptoms, and neurocognitive outcomes that may either intensify or ameliorate secondary injury, for children with a traumatic brain injury. Exploring the apo-E genotype will help us know if injury response is altered in certain children and will aid in developing interventional approaches.
The purpose of this study is to determine whether sildenafil (Viagra®) is effective in improving cerebral blood flow and cerebrovascular reactivity inpatients who have persistent symptoms at least 6 months after a traumatic brain injury (TBI).
The aim of this study is to compare the effect of transcranial direct current stimulation and functional upper extremity task training to functional upper extremity task task training alone. The functional upper extremity task training takes uses the Armeo Spring robotic arm to support the limb while playing functional task games on the computer. Specific Aims: 1. To demonstrate that tDCS combined with upper extremity functional task training in a virtual environment is more effective than functional task training in a virtual environment with sham tDCS. 2. To compare cortico-excitatory changes following training with tDCS vs. sham stimulation, using paired- and single-pulse transcranial magnetic stimulation as a tool to measure cortical excitability.
The present study addresses problematic anger and irritability in community dwelling persons with traumatic brain injury (TBI). It is designed to test the worth of a novel treatment approach called Anger Self-Management Training (ASMT), compared to a treatment offering supportive therapy focused on personal readjustment and education, the PRE (Personal Readjustment and Education). The project is a 3-center randomized controlled trial employing equivalent therapist time and therapeutic structure in the delivery of treatment options. The overall aim is to evaluate the relative response rate and correlates of treatment response for the ASMT as compared to the PRE.
Blood samples will be drawn on traumatic brain injury patients who are participating in the ProTECT III study.
