Filter by:This study investigates the efficacy of a novel neurorehabilitation program combining noninvasive brain stimulation (transcranial magnetic stimulation or TMS) and cognitive therapy, on cognitive function and quality of life in individuals with blast-induced traumatic brain injury (bTBI).
The investigators will obtain thromboelastography (TEG) on pediatric patients admitted to the Rady Children's Hospital ICU after traumatic brain injury on admission to our ICU and after 24 hours of care. The investigators hypothesize that TEG will identify abnormalities of coagulation that are not identified by traditional coagulation studies, i.e. prothrombin time (PT), activated partial thromboplastin time (aPTT), and international normalized ratio (INR).
Peripheral nerve stimulation for the treatment of sequelae due to traumatic brain injury. This study will specifically examine patients with mild traumatic brain injury (TBI) who have persistent cognitive impairments lasting one year or longer. Neuropsychological testing will occur to confirm the diagnosis.
The goal of this phase of the project is to identify the elements of the Theory of Planned Behavior (TPB) that should be targeted to provide the most influence on older adults' behavior (or other stakeholders) to purchase and wear protective headwear. The investigators also intend to determine the format of communication (social marketing/academic detailing) that is most influential for different key stakeholder groups. The TPB has been useful in understanding behavior change related to exercise and adaptive equipment use (such as grab bars, canes, hip protectors); in understanding how a person's attitudes, subjective/social norms and perceived behavioral control inform the development of intention that leads to behavior change.
The purpose of this study is to determine if bone marrow harvest, BMMNC separation, and re-infusion in adults with acute severe TBI is safe and will improve functional outcome. 12/09/2015 Update: The study is closed to new enrollment and all follow-up visits have been completed. Data analysis is underway.
Background: Although glucose is essential to cerebral function, abundant experimental and clinical evidence demonstrates that endogenously released lactate, rather than glucose, is the preferential energy substrate for the brain in conditions of stress and acute injury. In patients with severe Traumatic Brain Injury (TBI) and aneurysmal subarachnoid hemorrhage (SAH) monitored with cerebral microdialysis and brain tissue oxygen (PbtO2), our preliminary data show that increased brain extracellular lactate is frequently observed. Our findings indicate that elevated brain lactate more often occurs in the absence of brain hypoxia/ischemia and is mainly the consequence of increased cerebral glycolysis, i.e. it occurs in association with high extracellular pyruvate. These data suggest that the primary source of elevated lactate is activated glycolysis and strongly support the concept that endogenously released lactate can be utilized by the injured human brain as energy substrate. They prompt further investigation to examine whether exogenous lactate supplementation can be a valuable neuroprotective strategy after TBI or SAH. Indeed, in animal models of brain injury, administration of exogenous lactate improves neuronal and cognitive recovery. Hypothesis: The investigators test the hypothesis that lactate therapy, administered during the acute phase of TBI or SAH, might exercise neuroprotective actions by restoring brain energetics and improving brain tissue PO2 and cerebral blood flow (CBF). Aim of the study: The aim of this single-center study is to examine the effect of sodium lactate infusion on cerebral extracellular metabolites, brain tissue PO2 and cerebral blood flow, measured with CT perfusion and transcranial doppler (TCD). Design: Prospective phase II interventional study examining the effect of a continuous 3-6 hours infusion of sodium lactate (20-40 µmol/kg/min), administered within 48 hours from TBI or SAH, on cerebral extracellular glucose, pyruvate, glutamate, glycerol, PbtO2 and CBF.
The global aim of this proposal is to test and refine Common Data Elements (CDEs), neuroimaging standards, and best practices for genetics and proteomics in Traumatic Brain Injury (TBI) studies. Testing and validating of TBI-CDEs will be performed in a multi-center prospective observational study with 3 TBI Centers (San Francisco General Hospital (SFGH), University of Pittsburgh Medical Center (UPMC), University Medical Center Brackenridge (UMCB)) and a TBI Rehabilitation Center (Mount Sinai Rehabilitation Center (MSMC)). The investigators will create and expand existing data repositories for patient demographics, neuroimaging, plasma biomarkers, genetics, and multivariate outcomes thereby providing researchers and clinicians with the infrastructure to establish multidisciplinary, multicenter research networks and improve clinical research in the TBI field.
This study is being done to improve the ability to diagnose and to achieve higher-levels of functional recovery in soldiers and civilians who have suffered either mild Traumatic Brain Injury (TBIs) or moderate-to-severe TBIs at chronic stages of brain recovery (greater than 12 months).
The use of Event Related Potentials (ERP) and neurocognitive performance in patients following concussion has been examined previously in small cohorts and relatively long after concussion occurred. However, little is known about the immediate changes in brain activity in specific brain regions and connectivity across them associated with performance on specific neurocognitive tests following a concussion, and the subsequent changes over time. The proposed study will provide initial evidence for the feasibility of an ERP based biomarker for concussion reflecting temporal and spatial changes in brain activity as well as brain functional connectivity associated with concussion.
The purpose of this study is to learn if a new brain imaging technology called DaTscan can detect subtle changes in the brain that are similar to those seen in early Parkinson's disease (PD). The results of this study may provide more information about a possible association between mild to moderate traumatic brain injury (mTBI) and PD. The objectives of this study are to define and describe a group of approximately 7,122 mTBI subjects and 7,122 subjects without mTBI (mTBI-) seen in the Emergency Rooms of NorthShore University HealthSystem during the years 2006-2011, and to select from willing eligible subjects a random sample of 100 mTBI subjects and 100 mTBI- subjects (of the same age and gender) to undergo written informed consent, neurological examinations, blood drawing for DNA extraction and storage, and DaTscan brain imaging. The investigators will compare the findings from persons who experienced mTBI (cases) to persons without a history of brain injury (mTBI- or "controls").
