Active clinical trials for "Brain Injuries, Traumatic"

The primary aims of this study are to: 1) Establish the concurrent criterion-related validity of four traumatic brain injury (TBI) screening questions (TBI-4) using the Ohio State University TBI Identification Method (OSU TBI-ID) and 2) Establish the concurrent criterion-related validity of the TBI-4 with the addition of detailed information elicited by the four questions. Secondary aims include: 1) Determining if the addition of detailed information elicited by the TBI-4 results in increased specificity; 2) Determining whether the prevalence of traumatic brain injury (TBI) in this sample is concordant with previous research; and 3) Determining whether psychiatric outcomes are worse for veterans with traumatic brain injury (TBI) than those with no traumatic brain injury(TBI).

Objectives include: 1) establishing a psychometrically sound traumatic brain injury (TBI) screening measure for use among homeless veterans; 2) identifying the prevalence of those that screen positive for TBI among homeless veterans seeking VA services; and 3) comparing psychiatric and psychosocial outcomes between those with and without a history of TBI.

We will utilize a set of imaging modalities including computed tomography (CT), positron emission tomography (PET), and a suite of magnetic resonance imaging (MRI) tools, to investigate the changes in the human brain resulting from mild traumatic brain injury (mTBI).

The purpose of the study is to determine if a specific blood protein, S-100B, can help predict who will have a traumatic abnormality on head CT scan after a concussion. We will compare the levels of this protein in the subject's blood to the initial head CT scan and to how the subject is feeling one month after injury. We hope that the information we collect in this trial will help us determine who needs a head CT scan after a concussion and who may be more likely to have trouble recovering from a concussion.

The primary objective of the clinical trial is to evaluate the effect of time on levels of Ubiquitin C-terminal Hydrolase-L1 (UCH-L1) and Glial Fibrillary Acidic Protein (GFAP) biomarker levels in a population of head injured subjects over the age of 18 presenting acutely with a Glasgow Coma Scale score 13-15 as well as in a group of uninjured control subjects.

To learn more about how a family treatment program helps people after brain injury. Specifically, do families feel better and function better after going through the program, and do patients feel better and function better after going through the program.

This is a prospective study enrolling 5 patients with a diagnosis of traumatic brain injury (TBI) without polytrauma and 5 patients with TBI with polytrauma admitted to the University of Kentucky (UK) Chandler Medical Center to evaluate differences in platelet bioenergetics in the populations. Additionally, five healthy subjects will be recruited to the control group.

Traumatic brain injury (TBI) affects 1.7 million people in the United States each year, resulting in 2.5 million emergency department visits, 280,000 hospitalizations, >50,000 deaths, and more than $60 billion in economic cost. TBI also affects >30,000 military personnel annually and almost 8% of veterans who received care between 2001 and 2011. Post-traumatic neurologic outcome depends on the severity of initial injuries and the extent of secondary cerebral damage. Ischemia is the most common and devastating secondary insult. Ischemic brain damage has been identified histologically in ~90% of patients who died following closed head injury, and several studies have associated low cerebral blood flow (CBF) with poor outcome. Specifically, CBF of less than 200 ml/min has been shown to be the critical lower threshold for survival in neurointensive care patients. In addition to intracranial hypertension and cerebral edema, systemic hypotension and reduced cardiac output contribute substantially to posttraumatic cerebral ischemia. Additionally, the carotid artery is the most common site of blunt cerebral vascular injury (BCVI), which may further compromise CBF and cause subsequent death or debilitating stroke. Specifically, high grade internal carotid arterial (ICA) injuries are associated with the highest mortality and stroke rate. The investigators' goal is to develop of a wearable noninvasive, continuous, automated ultrasound sensor to accurately measure extracranial ICA flow volume. In doing so, the investigators aim to enable early detection of CBF compromise, thereby preventing secondary ischemic injuries in TBI patients. To achieve this goal, the investigators plan to first build a prototype wearable ICA ultrasound senor with integrated signal processing platform, then test its accuracy in an in vitro system and healthy human subjects.

The purpose of this study is to determine whether there is a difference in cerebral oxygenation as measured by near-infrared spectroscopy (NIRS) in children with concussion and healthy controls.

The purpose of this study is to examine differences in post-concussive (PC) symptom endorsement among four groups of Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF) Veterans: those with a history of target, service-related, mild traumatic brain injury (mTBI) and co-occurring posttraumatic stress disorder (PTSD) (Group 1); those with a history of target, service-related, mTBI only (Group 2); those with PTSD only (Group 3); and those with no history of target, service-related, mTBI or PTSD (Group 4) by examining scores on the Neurobehavioral Symptom Inventory (NSI). Support for this study is provided by previous research highlighting the complex relationship between mTBI, PTSD and subsequent PC symptom endorsement (Brenner et al. 2010; Terrio et al, 2009). HYPOTHESES ARE AS FOLLOWS: Individuals with a history of target, service-related, mTBI only (Group 2) and individuals with PTSD only (Group 3) each will report significantly more PC symptoms, as measured by NSI total scores, when compared to those with no history of service-related mTBI or PTSD (Group 4). Individuals with co-occurring target, service-related, mTBI history and PTSD (Group 1) will report significantly more PC symptoms, as measured by total NSI scores, than either those with target, service-related, mTBI only (Group 2) or those with PTSD only (Group 3).
