Filter by:Intracranial pressure (ICP) in patients with traumatic brain injury (TBI) is influenced by several factors of which one is arterial CO2 tension. Patient with TBI are often sedated and mechanically ventilated in order to secure a stable PaCO2. This study compares two ventilation modus; Pressure Controlled Ventilation (PC) and Pressure Regulated Volume Controlled ventilation (PRVC) in order to observe which of the two ventilation strategies results in a more stable ICP and arterial CO2 pressure (PaCO2).
Aerobic exercise holds a multitude of health benefits. Studies in mice have shown that aerobic exercise improves memory, and increases the volume of the hippocampus, the brain's primary memory center. Only two studies have been conducted in humans, one in healthy elders, and the other in a schizophrenia population. So far, there has never been an aerobic exercise trial in traumatic brain injury (TBI) to look at hippocampal volume and memory as outcomes of interest. The proposed project is a randomized controlled trial of aerobic exercise in persons with TBI. We will conduct a 12-week (36 sessions) program of aerobic exercise (stationary cycling), versus a control condition of non-aerobic exercise (stretching), in memory-impaired TBI patients to a) increase hippocampal volume and b) improve memory. Importantly, we also expect benefits of aerobic exercise on the level of brain function. Specifically, we will look at 'functional connectivity,' which refers to how efficiently remote regions of the brain 'talk' to each other. TBI is an ideal population to benefit from aerobic exercise, given the young age at which many individuals sustain TBI, which allows for benefits of aerobic exercise to be maximally realized in a population with sufficient neurofunctional reserve. The expected benefits of aerobic exercise (increased hippocampal volume, improved memory) from this intervention stand to have a meaningful impact on people with TBI, including improved health, productivity, independence, and quality of life. And, unlike current treatments for memory impairment (e.g., pharmacological agents, cognitive rehabilitation), aerobic exercise is a cost-effective, all natural, readily-available treatment for memory problems.
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.
Background: - Research has shown that one exercise session may improve a person s ability to recall information they learned before the exercise. Knowing how exercise changes brain activity to improve memory can help researchers understand how memory works and how to improve it in people with memory problems. This study compares two kinds of exercise on a stationary bike for their ability to temporarily improve memory on certain tests. Researchers will look at the effect of exercise on body chemistry by drawing blood and collecting saliva. Objectives: - To understand how a single session of exercise affects memory testing in healthy people and people who have had traumatic brain injury (TBI). Eligibility: - Adults ages 18 through 45 with TBI. - Healthy adult volunteers, ages 18 through 45. Design: - Participants will be screened with medical history and physical exam. This will take about 1 hour. - Participants with TBI will also be screened with a test of their memory. This will take another hour. - Visit 1 will take about 3 hours. Participants will: <TAB>- Have a tube inserted in their arm for drawing blood during the tests. <TAB>- Take memory tests. They will look at pictures, symbols, and words, then answer questions. <TAB>- Give a saliva sample by chewing on a small sponge for 2 minutes. <TAB>- Exercise on a stationary bike. <TAB>- Take the memory tests again. - Visit 2 will take place 1 week later. Participants will take the memory tests only.
1. To evaluate the efficacy of a structured outpatient couples intervention program (Therapeutic Couples Intervention, TCI) on couples' marital quality after acquired brain injury (ABI). 2. To assess the impact of the TCI on the emotional well-being of persons with ABI and their partners. 3. To ascertain the impact of the TCI on caregiver burden and unmet needs as reported by partners of persons with ABI. 4. To examine the extent to which treatment benefits for survivors and their caregiving partners are sustained in the longer-term.
1. To evaluate the short and longer-term efficacy of a structured outpatient intervention program (The Resilience and Adjustment Intervention, RAI) to improve survivors' resilience. 2. To evaluate the impact of treatment on emotional well-being and postinjury adjustment. 3. To evaluate the impact of the intervention on abilities including problem solving, communication, and stress management. 4. To examine the extent to which treatment benefits are sustained in the longer-term.
Traumatic Brain Injury (TBI) - methylphenidate treatment
To measure Axonal Injury in children with mild traumatic brain injury enrolled in an Emergency Department using Diffusion Tensor Imaging, a type of MRI and biomarkers.
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.
