Filter by:Blood flow through the brain is reduced after brain damage. Secondary brain ischemia caused by hypoxia and hypotension, further increase the susceptibility of the ischemically compromised brain to secondary impairment during this period. In order to determine whether and to what extent blockage of the stellate ganglion (BSG) affects the blood flow to the injured brain, the investigators will measure the variables of brain blood flow before and after BSG using computed tomography angiography (CTA), trans-cranial Doppler ultrasound (TCD), intracranial pressure (ICP) and perfusion computed tomography (PCT) of the brain. At the same time, the investigators would like to evaluate whether and to what extent BSG affects the aseptic inflammatory brain injury response and the biochemical indicators of brain damage in patients with moderate and severe brain injury.
Traumatic brain injury (TBI) is highly prevalent and frequently comorbid among Veterans and Service Members. Many of these individuals sustain more than one TBI over the course of their military careers, often with little recovery time between exposures placing them at increased risk for persistent cognitive, psychological, and psychosocial difficulties that impact daily functioning and life satisfaction. The short-term objective of this study is to examine the efficacy of the manualized, 10-week, telephone delivery of Tele-CABA for improving cognitive and adaptive functioning. The long-term objective of this study is to develop an accessible and acceptable intervention that can be broadly disseminated to address the complex rehabilitation needs of Veterans and Service Members. The overall goal of the Tele-CABA intervention is to reduce negative cognitive and psychiatric health outcomes for Veterans and Service Members with a history of TBI, promote personal resilience, and to design an intervention that is accessible and acceptable to patients struggling to recover from TBI.
The investigators will test the central hypotheses according to the following Specific Aims: Aim 1. Determine if an individually prescribed exercise program initiated within the first week of mild traumatic brain injury can reduce the risk of developing persistent post-concussion symptoms relative to usual care. The investigators hypothesize that the exercise group will have a lower risk of developing persistent post-concussion symptoms than the usual care group. Aim 2. Examine the effect of a two-month exercise program on psycho-social, pain interference, and sleep outcomes following mild traumatic brain injury. The investigators hypothesize the exercise group will report lower anxiety, depression, and pain interference ratings, and higher peer relationship and sleep quality ratings two months of exercise following mild traumatic brain injury compared to usual care.
The purpose of this research study is to develop a method to improve thinking difficulties in individuals who have experienced a traumatic brain injury and report experiencing difficulties in attention and concentration. This study aims to understand how cognitive rehabilitation of attention difficulties affects brain activity.
The purpose of this research study is to compare the effect of two different types of group wellness interventions for partner caregivers of individuals with traumatic brain injury (TBI). The study is designed to evaluate how well these treatments can help TBI partner caregivers improve approach/avoidance behaviors.
Methylation of the brain-derived neurotrophic factor (BDNF) gene is involved in both the biological encoding of childhood adversity and neuroplasticity following traumatic brain injury (TBI). This research will characterize BDNF methylation during recovery from TBI in children and investigate this novel biomarker as a potential biological mechanism underlying the known association between childhood adversity and poorer neurobehavioral outcomes following TBI in childhood. Findings from this research will contribute to an improved understanding of why some children display good recovery following TBI, whereas many others suffer from chronic neurobehavioral impairments.
The objective of this research study is to find the efficacy of trans-spinal electrical stimulation, a non-invasive neurostimulation method to modulate the functions of spinal cord neurocircuits, on improving upper-extremity functions such as reaching and grasping in individuals suffering with traumatic brain injury (TBI) or cervical spinal cord injury (SCI); and to find the physiological changes in the neuromuscular systems after this new intervention with high-resolution electrophysiology and biomedical imaging.
Lay Summary: To evaluate a novel early diagnostic tool for hospitalized children with traumatic brain injury. The Problem: Children who present with decreased level of consciousness after injury require urgent medical attention determined by the type and the severity of injury. Unfortunately, history and physical findings are often unreliable in the first hours after hospitalization, the period in which urgent management decisions must be made for their treatment. The Solution: A promising tool developed for measuring detectable evidence of traumatic brain injury on routine brain scans. The tool combines features invisible to the human eye but detectable by computer software with expert knowledge.This study will evaluate how well the tool can perform in a real health care setting. It is believed that it will greatly improve the efficacy and quality of care provided to children after traumatic brain injury.
The goal of this study is to evaluate the i-STAT TBI test to assist determining the need for a computed tomography (CT) scan in patients with suspected mild traumatic brain injury (TBI). Patients will be asked to provide a blood sample.
The affectedness of the motor control of the upper limb, particulary, the hand and/or fingers, appears in many neurological diseases, what is going to impact on the functionality of the subject. The use of new technologies in the rehabilitation environment, has the target to reduce the impact on the disabling conditions. So that, the goal of this investigation is to evaluate the system use effectiveness of the Leap Motion Controller® in the treatment on the upper limb on patients with neurological disease.
