Active clinical trials for "Brain Injuries, Traumatic"

The purpose of this study is to develop a highly portable, ruggedized diagnostic tool for concussion, EyeBOX Lens (EBLens), that can be utilized in deployed field and far-forward settings. The EBLens will be based on a concussion diagnostic algorithm from the FDA cleared EyeBOX device, developed by Oculogica, and eye-tracking data collected from a wearable set of eye-tracking glasses, developed by Adhawk Microsystems. Once the EBLens is prototyped, an algorithm for diagnosing concussion will be developed that is specifically appropriate for the EBLens via a case-control clinical study comparing 100 concussed to 100 non-concussed subjects (Phase I). Participants, age 18-35 years, will be recruited from the KACH research team and affiliated providers and clinical sites. Concussed individuals will be assessed within 72 hours of concussion. Demographics, basic medical history, symptom severity, a visio-vestibular exam and the EBLens scan will be collected on both injured cases and uninjured controls at a single time point. The algorithm and the EBLens will be validated in a subsequent, prospective cohort validation study (Phase II) designed for FDA submission. The correlation of the EBLens output with resolution of symptoms will also be observed in longitudinal follow-up of concussed participants in the validation study. The participant population for this study will be cadets recruited from the USMA and young athletes recruited from affiliated sites during baseline concussion testing. Participants will be assessed at baseline at the start of their academic year or sports season. Those participants who experience a concussive injury will be assessed again at three time points; 1) within 72 hours of injury, 2) weekly until and at the time of initiation of a graded return to activity protocol, and 3) upon clearance for unrestricted RTP/RTD.

When fever is present in patients with stroke, traumatic brain injury (TBI), or brain hemorrhage, it has been associated with worse outcomes including larger areas of tissue death, increased length of stay, worse degree of coma, lower ability to function, and higher mortality. Both adult and pediatric TBI national guidelines state that maintenance of normal body temperature should be a standard of care. However, no further standards or options are presented to specifically guide practice. The current ischemic stroke guidelines state that fever should be treated with fever-reducing agents and offer "cooling devices" as an option but do not provide specifics to guide practice. Over 50% of patients in the Neurosurgical Intensive Care Unit (ICU) at Harborview Medical Center develop fever during the course of their stay. With elevated temperatures the body consumes more oxygen than if the temperature was normal, causing less oxygen to be available to the brain. This may lead to injury of the brain cells and a diminished capacity for healing. Thus, temperature management in neurologically vulnerable patients is both a prevalent and problematic challenge. Based on this information the goal of the present proposal is to evaluate if 1) A standardized, step-wise approach to temperature management using a Normothermia Protocol is successful in achieving and maintaining normal temperature in Neurosurgical ICU patients; and 2) If maintenance of normal temperature will be associated with fewer episodes of diminished responsiveness in their neurological exams as evidenced by a measure of depth of coma, as measured by the Glasgow Coma Score (GCS) compared to a control group treated according to usual care.

Studies in patients with disorders of consciousness (DOC) after severe brain injury implicate dysfunction of the anterior forebrain mesocircuit dysfunction a key underlying mechanism. The anterior forebrain metabolism in DOC is markedly downregulated across brain regions underpinning highly elaborated cognitive behaviors demonstrating a collapse of the level of synaptic background activity required for consistent goal-directed behavior and arousal regulation. Since dopamine levels are one of the primary controllers of the level of synaptic background activity within these forebrain structures and in regulating excitatory glutamatergic homeostasis, the investigators propose to investigate the specific contribution of presynaptic dopamine function in glutamatergic neurotransmission in posttraumatic DOC. The aim of the present study is to measure metabotropic glutamate receptors 5 occupancy in the main gutamatergic structures of the brain using (3-[18F]fluoro-5-(2-pyridinylethynyl)benzonitrile)-positron emission tomography ( [18F]FPEB-PET) at rest and following a short pharmacological challenge with amantadine, an N-methyl-D-aspartate receptor (NMDA-R) antagonist, following L-DOPA, and amantadine + L-DOPA. Using this novel technique in DOC the investigators will characterize the relevance of a presynaptic deficiency to synthesize and/or release dopamine in the final regulation of excitatory interneurons of the anterior forebrain mesocircuit. It is unknown whether glutamatergic neurotransmission is affected across the population of subjects with DOC and, if this condition is secondary to a presynaptic dopaminergic failure of the anterior forebrain mesocircuit (i.e., down-regulation). Since the investigators previously identified the existence of a presynaptic dopaminergic deficit in these subjects due to a failure in the biosynthesis of dopamine, the investigators will evaluate if by providing the main biological substrate of the biosynthesis process (i.e., L-DOPA) the glutamatergic system regains homeostasis. The investigators therefore propose to investigate patients with posttraumatic DOC using [18F]FPEB-PET at rest and following short pharmacological challenges aimed at increasing glutamate and dopamine release.

A traumatic brain injury (TBI) is among the most frequent reasons for neurological impairment in young people. The investigators investigated whether vitamin B12 vs B3 therapy could reduce the severity of traumatic brain injury (TBI) due to their positive effects on axon regrowth following nerve damage. The method utilized was a series of non-random samples. With a 95% confidence interval and a 5% margin of error, a total sample of 300 patients was estimated using Epi Info. Participants in our study comprised both boys and girls with severe TBI ages 6 to 15 years old. Two groups of 300 children were recruited. B3 (16 mg/day) was administered to group 1 and B12 (125-250 mcg/day) was provided to group 2. It is evaluated through follow-ups on a range of tests to evaluate cognitive capacity, sensorimotor activity and staircase test (working and reference memory). Pre-and post-treatment GCS measurements were conducted. Three weeks and a year following the treatment of TBI, children underwent neurobehavioral testing. The measurement of gait analysis was done. The standard error and mean of statistically examined data were shown by paired t-test.

Thirty-six years old male with a history of TBI with compromised functionality of the right upper and lower limbs, spasticity, distributed balance, and difficulties performing independent gait has participated in the study. Berg balance scale, 6-minute walk test, modified Ashworth scale, and functional independence measure was used to assess balance, gait, spasticity, and functional intemperance, respectively.

Traumatic Brain Injury (TBI) is the leading cause of death and disability across the globe. Time from injury to treatment is the most critical factor that determines the patient's recovery. Mild TBI with no apparent symptoms are often left undiagnosed, thus delaying the treatment and hence recovery. CEREBO® is a non-invasive, rapid, near-infrared based, point-of-care device that can detect an intracranial bleed at an early stage.

This is a preliminary, prospective interventional study to investigate the feasibility of using transcutaneous alternating current stimulation (TACS) and transcutaneous noninvasive vagal nerve stimulation (tnVNS) after a traumatic brain injury (TBI) to improve cognitive function and decision-making.

The specific aims of the proposed study are to evaluate: 1) the feasibility of design elements of a Strength and Awareness in Action: an Intervention for Post-Acute TBI Headaches (SAA-TBI) intervention trial (e.g., an exercise run-in to facilitate participant retention); 2) yoga instructor fidelity; and 3) variability estimates for candidate proximal and distal outcomes. Performance of validated measures, including those associated with quality of life, as well as data collected via ecological momentary assessment and pedometry (physical activity) will be evaluated.

The current study seeks to evaluate cognitive behavior therapy for insomnia (CBT-I), a non-medication treatment, in recent TBI patients compared to a sleep education control intervention. Patients will participate in CBT-I treatment (or sleep education treatment) weekly for six weeks, and will have a 3-months follow-up visit in order to examine the efficacy and time course of treatment. In addition, participants will complete several self-report questionnaires in order to examine sleep and neuropsychiatric symptoms throughout treatment.

The purpose of this study is to determine if clinic and home training with a study device will improve a balance deficit. The study device is called Portable Neuromodulation Stimulator (PoNS). The study device will be placed on the tongue to deliver nerve stimulation. The study is testing if use of the study device in conjunction with physical therapy will improve balance and gait in patients suffering from a TBI. The effects of using the device and undergoing therapy will be measured using standardized tests of movement control, gait, headache and other TBI symptoms.
