Filter by: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.
To identify the changes in the brain following repeated sports-related concussion in men's football, women's soccer, and women's lacrosse college athletes by reviewing the findings of MRI studies that look at the structure of the brain and the appearance of the white matter at baseline, during the acute phase of a concussive injury, and upon completion of collegiate athletic play and correlate these findings with standard clinical measures.
The purpose of this study is to demonstrate proof of clinical concept that application of the Intrathoracic Pressure Regulator (ITPR) will result in an increase in Cerebral Perfusion Pressure (CPP) and a decrease in Intracranial Perfusion Pressure (ICP) in patients with head injury and elevated ICP, and to determine the optimal ventilation tidal volume (TV).
The purpose of this study is to evaluate safety, tolerability, pharmacokinetics (explores what the body does to the drug) and pharmacodynamics (the study of the action or effects a drug has on the body) of JNJ-17299425 in participants with traumatic brain injury (acute and chronic injuries to the brain, including the cerebral hemispheres, cerebellum, and brain stem).
The purpose of this study is to determine if specific brain injury biomarkers have utility as blood-based traumatic brain injury (TBI) diagnostic and monitoring tools. This will be accomplished by examining the relationships between potential serum-based TBI biomarkers and clinical measures of injury severity, occurrence of complications, and outcome, in subjects with mild or moderate TBI as well as in orthopedic control subjects.
Blood samples will be drawn on traumatic brain injury patients who are participating in the ProTECT III study.
This is a prospective randomized controlled pilot study in traumatic brain injury (TBI) patients who are sedated with either propofol or midazolam to compare the cytokine response and neuropsychological outcomes with and without elevated blood alcohol levels. Sedation is part of the standard treatment in patients with a TBI and has been proposed as a neuroprotective intervention in head-injured patients. Sedative regimens, such as midazolam and propofol, are not standardized and it is unclear whether sedation has a significant impact on recovery and outcome. A review of propofol versus midazolam in mechanically ventilated patients shows evidence that both provide effective sedation but there is lack of data to support one sedative over the other. Cytokines are released in response to tissue injury and act to generate a variety of physiologic responses. The cytokine elevation has been correlated with the extent of tissue injury. This study will compare the cytokine distribution patterns at specific posttraumatic time points in patients with a TBI sedated with either propofol or midazolam. Additional analysis will compare the cytokine response in patients whom had elevated blood alcohol levels with those with normal levels. Neuropsychological testing will also be performed to determine the extent of brain injury and recovery.
We will explore the use of Huperzine A in patients who have sustained a moderate to severe Traumatic Brain Injury. We aim to determine whether Huperzine A, as compared with placebo, would have an effect on memory function after TBI. Additionally, we aim to determine whether use of Huperzine A in these patients can change brain activity (as indexed by EEG and Transcranial Magnetic Stimulation - TMS), and reduce prevalence/frequency of post-traumatic seizures. We also aim to evaluate the safety of Huperzine A in this population as compared with placebo.
The purpose of this trial is to investigate safety and efficacy of Cerebrolysin as add-on therapy to standard care in patients with acute traumatic brain injury (TBI). The study duration for each patient is 180 days.
This research is being done to determine whether transcranial direct current stimulation (tDCS) can improve certain abilities related to cognition, emotion and/or physical functioning in individuals with subcortical brain damage.
