Active clinical trials for "Brain Injuries, Traumatic"

The use of Event Related Potentials (ERP) and neurocognitive performance in patients following concussion has been examined previously in small cohorts and relatively long after concussion occurred. However, little is known about the immediate changes in brain activity in specific brain regions and connectivity across them associated with performance on specific neurocognitive tests following a concussion, and the subsequent changes over time. The proposed study will provide initial evidence for the feasibility of an ERP based biomarker for concussion reflecting temporal and spatial changes in brain activity as well as brain functional connectivity associated with concussion.

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: 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. It is hypothesized that there will be a relationship between FA, cognition and emotion as a function of the injury. It is hypothesized that functional connectivity will be related to FA.

The purpose of this study is to record signatures from the fluid surrounding the spinal cord from people who have an implanted drug infusion system.

The purpose of the proposed study is to determine the clinical validity and reliability of the VA's Traumatic Brain Injury (TBI) Clinical Reminder Screen and the Comprehensive TBI Evaluation used to screen for mild traumatic brain injury. Examining the reliability of the two screens will determine whether they are dependable. Verifying the clinical validity is important because valid screening and evaluation of mild TBI leads to accurate diagnosis and timely treatment. Accurate screening also improves clinical efficiency and ensures that resources are provided to those who need them most. The project findings are expected to advance the science of screening and diagnosis of a mild TBI event.

The investigators propose to develop quantitative automated lesion detection (QALD) procedures to identify brain damage following traumatic brain injury more accurately than is possible with a normal magnetic resonance imaging (MRI) scans. These procedures require about 1 hour of imaging in an MRI scanner. Subjects will also undergo about 2 hours of cognitive tests. The investigators will compare the results of the cognitive tests with those from MRI scanning to determine what brain regions are responsible for superior performance and for performance decrements.

Objectives: The ultimate goal of this research program is to promote seamless, comprehensive care for Operation Enduring Freedom/ Operation Iraqi Freedom (OEF/OIF) veterans. The purpose of this study is to develop a psychometrically sound tool to measure health-related quality of life (HRQOL) applicable to wounded warriors with TBI (deployment-related TBI).

The Alfred Hospital receives approximately 40% of the major trauma patients in Victoria, all of whom are at risk for spinal injuries. The potential for spinal injuries necessitates the undertaking of appropriate spinal investigations, and a delay in the completion of these investigations exposes the patient to the risk of a missed diagnosis of spinal instability and of complications of immobility; the potential spinal patient is required to wear a neck collar and be nursed lying flat whilst awaiting the completion and the appropriate documentation of spinal X-ray investigations. The purpose of this study is to identify the issues causing a delay in the process of the completion of the appropriate spinal investigations and the documentation of the results. The outcome of the proposed research will be the development of a clinical management protocol to expedite the process, with the aim of optimising patient care and reducing complications.

The purpose of this study is to examine the validity of the Russian version of the FOUR Full Outline of UnResponsiveness (hereafter FOUR) scale in adult ICU patients with an acute cerebral insufficiency clinic (hereinafter referred to as OTSN). Compare the accuracy and predictive significance of FOUR when used by an ICU specialist, a neurologist, nursing staff, during bedside and telemedicine Examinations.

This study was conducted to develop and validate integrated eye tracking and EEG measures for assessment of mild traumatic brain injury.

The aim of the study is to look if Quick Sequential Organ Failure Assessment Score score in detecting a eary Sepsis is afflicted by neurosurgical disorders
