Active clinical trials for "Brain Injuries"

Mild traumatic brain injury (mTBI), also known as concussion, occurs commonly in sport. Despite ongoing research, there is no highly sensitive clinical test for cognitive function. This makes the clinical diagnosis of concussion particularly difficult as the clinical presentation of concussion is highly variable with symptoms often evolving over time. Given the variability in concussion presentations, there is no single test that can diagnose a concussion. Current recommendations are that sports medicine providers apply a multifaceted concussion assessment battery that combines subjective symptoms, motor control and cognitive assessment. This investigation is designed to evaluate the clinical utility of ElMindA's BNA scores in detecting and managing concussive injuries. This study will establish the reliability of BNA™ scores over clinically relevant assessment intervals and investigate the effect of SRC and sub-concussive head impacts on BNA scores.

Circulating progenitor cells (CPC) treatments may have great potential for the recovery of neurons and brain function. Our group has reported how exposure to intermittent hypobaric hypoxia with superficial muscle electrostimulation is able to increase the concentration of CPC in peripheral blood in humans. Therefore, we believe that through physical activities and exposure to intermittent hypobaric hypoxia for a period, it will increase CPC in the blood of subjects who have suffered a severe Traumatic Brain Injury (TBI) one or more years ago, promoting regeneration and functional and cognitive recovery. The study primary end-point is to improve physical or psychological functioning of participants with TBI with a program of exercise, muscle electro-stimulation (ME) and/or intermittent-hypobaric-hypoxia (IHH). Secondary end-points are to increase and maintain CPC and also to study their possible relationship with physical or psychological improvement of participants with Traumatic Brain Injury (TBI). In order to achieve these objectives investigators have designed a randomized controlled trial that will include those patients who suffered severe TBI more than one year previously with physical or psychological sequelae. Exercise, muscle electro-stimulation (ME) and/or intermittent hypobaric hypoxia (IHH) programs will be applied during twelve weeks. Psychological and physical stress tests will carry out before and after the program and CPC will measure at the beginning, every two weeks, and at the end of the program.

Angiogenesis is an important pathophysiological response to traumatic brain injury (TBI) and modulated by pro- and anti-angiogenic factors. Recent studies have suggested that endogenous angiogenesis inhibitor endostatin/collagen XVIII might play an important role in the secondary brain injury following TBI. The aim of this study was to investigate early changes in the concentrations of CSF endostatin/collagen XVIII after TBI and evaluated the relations of endostatin/collagen XVIII to injury severity and clinical outcome. Endostatin/collagen XVIII concentrations were measured serially for 1 week after hospitalization by using the enzyme linked immunosorbent assay method in the cerebrospinal fluid of 30 patients with TBI and a Glasgow Coma Scale score of 8 or less on admission. Comparative analysis were used to determine if its serial changes correlate with the GCS score and prognosis. Receiver operating characteristic curve was used to appraise the value of CSF endostatin/collagen XVIII levels in predicting the prognosis of patients with severe head injury.

The aim of the study is to measure the effect of Finnish physician-staffed EMS unit treatment methods on traumatic brain injury (TBI) patient prognosis.

Hospitalized patients are often moved from their rooms to other hospital locations, particularly imaging facilities. For patients with traumatic brain injury, such movements may raise the risk of secondary brain injuries. The purpose of this study is to monitor brain injured patients during transport and to measure the resulting changes in intracranial pressure. This will allow for documentation of the frequency of secondary injury and help in understanding their causes.

Goal: The ultimate goal of this research program is to improve the health and quality of life for wounded warriors from Operations Enduring Freedom and Iraqi Freedom (OEF/OIF) through screening, risk assessment, and outcome measurement. Purpose: The purpose of this study is to evaluate the reliability and validity of the existing Traumatic Brain Injury (TBI) Clinical Reminder Screen for OEF/OIF Veterans.

The scientific objective of this program is to meet the rehabilitation needs of combat wounded Veterans with mild to moderate Traumatic Brain Injury (TBI) via telerehabilitation and determine the effect of this modality of care on patients' physical health and outcomes including function and community participation. The investigators will also evaluate the benefits and limitations of rehabilitation using telehealth from the Veteran and caregiver perspectives and evaluate the impact of rehabilitation via telehealth on Veterans Administration (VA) healthcare facility use.

Following current standard-of-care, subjects data (brain pressure) will be recorded for 1 hour and include 10-minutes of data during which the subject recieves chest physiotherapy (CPT). The hypothesis is that CPT is not harmful to brain pressure.

Brain injuries from trauma are common in children, often resulting in death and disability. Most brain injuries are minor, yet their treatment can be challenging. Because there are many different scales used to characterize the severity of brain injury, there is no consensus regarding how to manage patients with minor brain injuries. Specifically, there is no agreement on recommendations regarding the safety of return to activities following injury. In young athletes with minor brain injuries (i.e. concussions) there is strong data suggesting that return to baseline neurologic function is often delayed by days or weeks. Children allowed to return to activities too soon may be at a higher risk for a second concussion, may delay recovery or, in rare cases, die. Researchers have designed a computer-based testing system (ImPACT©) to objectively test for neurologic deficits following injury. This test has been used primarily in athletes following a concussion but is also applicable to children with brain injuries from non-sports related traumas. We propose to utilize this testing in pediatric patients admitted to the hospital with minor brain injury. The test would be administered at the time of the hospitalization as well as in the outpatient trauma clinic at the time of routine follow up. The test would allow us to determine if there are neurologic deficits, potentially subclinical, in these brain injured patients and how quickly they recover from their injuries. If successful, the testing will likely be useful in other clinical settings such as the primary care office (e.g. pediatrician), specialty care office (e.g. sports medicine), or emergency room to determine if an injured child requires additional intervention.

Development of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) in patients with severe brain injury has been associated with poor outcome. The application of lung recruitment maneuvers (RM) for a short period of time to open collapsed alveoli and reverse hypoxemia in early ARDS has been recommended. However, little is known about the cerebral and vascular effects of RM in brain injury patients with ALI/ARDS. The aim of this study is to assess the effects of a single standardized RM on oxygenation and on systemic and cerebral hemodynamics in severe brain injury patients with ALI/ARDS.
