Filter by:This protocol is designed to facilitate the recruitment, screening and registry of Military Service Members (SMs) and individuals eligible for care in the Department of Defense (DoD) healthcare system. This protocol will serve as an entry point for SMs, retirees and other beneficiaries, to facilitate their participation in Center for Neuroscience and Regenerative Medicine (CNRM)-sponsored clinical research studies at participating CNRM sites. Specifically, this protocol will be comprised of an initial evaluation of participants, to include questionnaires, a blood draw, and neuroimaging. This evaluation will enable investigators to direct participants to CNRM-sponsored natural history, observational, or interventional protocols that are most relevant to the individual interests and needs of each participant. Other approved CNRM protocols may continue to recruit participants directly into their respective studies, and may refer participants to this study. The objective of this protocol is to develop a broad-spectrum military subject recruitment database that will collect and store preliminary data on research participants who are interested in and potentially eligible for current and future CNRM sponsored studies. The effectiveness of the recruitment methods utilized in this protocol will be evaluated to determine the most successful outreach approaches and recruitment tools for the enrollment of participants, including both active and reserve component SMs along with others who are eligible for care in the DoD healthcare system, who have experienced traumatic brain injury (TBI), psychological health (PH) concerns, or are interested in participating in studies as controls. Control participants may include (i) those with exposure to primary blast without the development of TBI, (ii) those with physical injuries without experiencing head injury, and (iii) healthy participants (non-injured, non-TBI, non-PH).
This study involves the treatment of cognitive impairment secondary to moderate to severe brain injury using central thalamic deep brain stimulation. Although all patients will receive stimulation continuously through a surgically implanted pacemaker-like device, half of the patients will have the device deactivated during a blinded assessment phase. The device will be reactivated following this assessment and patients will have the option to continue stimulation in an open-label continuation.
The primary goal of this study is to provide clinicians with a brief, patient self-administer instrument yielding a single composite score that reliably correlates with objective findings on standardized neurocognitive assessment for concussion.
This is a proof-of-concept study designed to demonstrate whether increases in cerebral blood flow, improvements in brain functioning, and reductions in symptomology associated with traumatic brain injury (TBI) can result from treatments consisting of near-infrared phototherapy (NIR).
The purpose of this study is to conduct a pilot trial investigating cognitive training in older Veterans with a history of traumatic brain injury (TBI) to assess training effects, acceptability of training to participants, and to explore whether other factors influence training effects.
Traumatic brain injury (TBI) is a leading cause of death and disability worldwide (Ghajar, 2000). With an estimated annual incidence of up to 500 per 100,000 population and more than 200 hospital admissions per 100,000 admissions in Europe each year, TBI is a major challenge to public health (Lingsma, 2010). Mortality and morbidity after TBI depend on several factors, either associated with patients characteristics, the cause of TBI, the neurological and general severity and secondary brain insults, the structural brain alterations as diagnosed at brain computed tomography (CT) (Rosenfeld, 2012). The prognostic value of brain CT characteristics is well documented, including the status of basal cisterns, midline shift, the presence and type of intracranial lesions, and traumatic subarachnoid hemorrhage (Maas, 2008). Postraumatic cerebral ischemia, which includes functionally impaired yet still viable tissue, so-called ischemic penumbra, and irreversible cerebral infarction (PTCI), is frequent in patients who die after moderate or severe head trauma (Stocchetti, 2014). Evidence of antemortem occurrence of PTCI is limited to three single-center retrospective studies, reporting a varying prevalence of 1.9%, 8% and 19.1% (Mirvis, 1990; Marino, 2006; Tawil, 2008). Increased intracranial pressure (ICP), blunt cerebral vascular injury, need for craniotomy and treatment with recombinant activated factor VII, have been demonstrated to be risk factors for PTCI. In one study, PTCI was an independent risk factor for poor outcome after moderate or severe head trauma with a two-fold increase in mortality and severe disability (Marino, 2006). PTCI can be an important diagnosis in patients with significant TBI for various reasons. First, it might influence long-term outcome. Second, as an outcome that is measurable, and relevant to survival and lifestyle, PTCI could be used as an outcome measure in randomized controlled trials. Third, diagnosis of PTCI could be used as a standard diagnostic reference to validate early surrogate indicators of cerebral ischemia. The investigators therefore planned a multi-center prospective study to investigate the impact of PTCI on disability at hospital discharge, and on 6-month morbidity and mortality in a population of moderate and severe adult TBI patients. The investigators also evaluated the role of intracranial hypertension, decreased cerebral perfusion pressure, hypotension and other secondary ischemic insults in determining the appearance of PTCI.
The purpose of this feasibility study is to determine whether digital games are effective and acceptable in the treatment for patients with traumatic brain injury.
This proposal will test the diagnostic utility of fast magnetic resonance (MR) in young children with Traumatic brain Injury (TBI). In children, TBI causes >2000 deaths, 35,000 hospitalizations and 470,000 emergency department visits in the US each year, making it a leading cause of pediatric disability and death. Currently 20-50% of these children undergo computed tomography (CT) scanning, exposing them to harmful radiation, and increasing their lifetime risk of cancer. Risks are especially increased in children because the neurologic exam is less reliable, because growing tissues are more vulnerable to radiation, and because children have more years to accumulate harmful mutations. Fast MR is a short, motion-tolerant protocol that has been used in children with shunted hydrocephalus to eliminate radiation exposure without the need for sedation. However, fast MR has not been validated in children with TBI, a critical gap. The investigators will measure feasibility and diagnostic utility of fast MR in children < 6 years (72 months) old who undergo head CT for TBI. The Investigator will recruit children in whom a head CT is ordered for TBI. Consenting subjects will undergo fast MR shortly after CT and results will be compared to determine: 1) whether fast MR identifies all traumatic injuries identified by CT and 2) whether fast MR without sedation can be performed quickly and successfully.
Effect of Extracorporeal Shock Wave Therapy on Chronic Neurogenic Heterotopic Ossification in Traumatic Brain Injured (TBI) patients Chronic Neurogenic Heterotopic Ossification (NHO) - Heterotopic ossification is a well known late complication of traumatic brain injury. Extracorporeal Shock Wave Therapy - ESWT- is used in various medical situations and is being tested for feasibility of use in TBI patients.
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).
