Filter by:Significant morbidity, mortality, and related costs are caused by traumatic brain injury (TBI). A simple, effective, and lightweight device worn by athletes or war fighters in the field, designed to mitigate TBI resulting from blast trauma or concussive events, would save lives, and the huge costs currently being experienced for life-treatment of surviving victims. An externally-worn medical device that applies mild jugular compression according to the principle of the Queckenstedt Maneuver (the Device) is being developed by Q30 Labs, LLC (Q30). Initial research suggests that the Device has the potential to reduce the likelihood of TBI. The rationale for testing wideband absorbance and Oto-acoustics emissions (OAE) is that the investigators need a physiologic, non-invasive method to evaluate the brain responses to mild jugular compression across multiple age groups. To determine this with MR imaging is currently cost prohibitive. The investigators pilot data from the parent IRB indicates a consistent response measured via wideband absorbance in young adults. Therefore, a preliminary step to evaluate the safety and efficacy of the neck collar device is to employ this technology across a wide range of ages.
Procure blood specimens from individuals presenting to the emergency department with suspected brain injury.
The ability to regulate impulses enables us to plan for the future, to maintain focus in the face of distractions (i.e. to encode memories), and to manage emotions. This self regulation can be compromised in individuals who have a history of mild traumatic brain injury and co-occurring disorders. In this study the investigators are using functional MRI scanning to understand how memory and self regulation are expressed in the brains of people with a history of mild traumatic brain injury. The investigators are also testing whether the medication tolcapone may improve memory and self regulation.
The purpose of this randomized control trial study is to determine if an active rehabilitation (low intensity exercise program) in combination with a comprehensive education intervention (standard care) is more effective than the comprehensive education intervention alone in reducing post-concussion symptoms and improving participation in daily activities in youth who have persistent post-concussion symptoms.
This is a four-site, randomized, parallel design, double-blind, placebo-controlled, 10-week trial of donepezil 10 mg daily for verbal memory problems among adults with TBI in the subacute or chronic recovery period. The study will recruit 160 persons with TBI and functionally important memory problems during a four-year period of open recruitment. The study aims are: 1. To evaluate the effects of treatment with donepezil on verbal memory as assessed by the Hopkins Verbal Learning Test-Revised Total Trial 1-3; 2. To evaluate the effects of treatment with donepezil on memory-related activities as measured by the Everyday Memory Questionnaire; 3. To evaluate the effects of donepezil on attention, processing speed, neuropsychiatric symptoms, community participation, quality of life, and caregiver experiences.
Mild traumatic brain injury (MTBI) is a common injury that involves loss of consciousness or alteration in mental status induced by an external mechanical force to the head. Education about symptoms and reassurance of a prompt recovery usually results in full recovery. However, a subgroup appears to have persistent symptoms and disability. This study will recruit MTBI patients from two Emergency Departments with the aim of identifying modifiable patient characteristics that can delay or prevent full recovery. A secondary aim is to determine if providing education in writing or in-person makes a difference.
The purpose of this study is to determine whether there is a quantitative relationship between brain processes seen by a MRI and visual deficits caused by mild to moderate traumatic brain injuries (mTBI).
The specific aim of this proposed study is to compare the effectiveness of Vestibular Rehabilitation (VR) in patients with PTSD who have suffered combat related traumatic brain injuries in a randomized controlled trial in terms of PTSD symptom reduction.
The purpose of this study is to determine if memantine can improve cognitive and neuropsychiatric outcomes after severe traumatic brain injury.
Increased intracranial pressure is a cause of disease progression in patients with brain disease, a common cause of poor prognosis. Intracranial pressure monitoring is the observation of the disease, treatment, evaluation and important way to improve the prognosis. Non-invasive intracranial pressure monitoring can be used to stroke, intracranial hemorrhage, brain trauma, encephalitis and other patients. Ophthalmic artery originated from the internal carotid artery, the optic canal into the orbit, the entire process can be divided into intracranial optic tube segment and orbital segment. investigators' preliminary experiments show that when intracranial pressure, intracranial ophthalmic artery segment velocity increases with increasing velocity difference orbital segment. Accordingly, the investigators speculate, may be judged by the level of intracranial pressure intracranial and orbital velocity difference between the ophthalmic artery segment, and accordingly calculate the specific values of intracranial pressure. The investigators will collect brain trauma surgery, performed invasive intracranial pressure monitoring cases, the use of transcranial Doppler ultrasound velocity and different segments of the ophthalmic artery pulsatility index, the invasive intracranial pressure and comparing the measured values to calculate the the critical value of the ophthalmic artery segment intraorbital and intracranial velocity difference when intracranial pressure, thus fitting Based on projections of mathematical formulas intracranial pressure. This study will provide a non-invasive intracranial pressure monitor new approach.
