- Traumatic brain injury may have a range of effects, from severe and permanent disability to more subtle functional and cognitive deficits that often go undetected during initial treatment. To improve treatments and therapies and to provide a uniform quality of care, researchers are interested in developing more standardized criteria for diagnosing and classifying different types of traumatic brain injury. By identifying imaging and other indicators immediately after the injury and during the initial treatment phrase, researchers hope to better understand the nature and effects of acute traumatic brain injury.
- To study the natural history of traumatic brain injury by examining the changes in brain scans, blood samples, and brain function over 5 years after a the injury.
- Individuals between 18 and 70 years of age who have had a traumatic brain injury within the past 6 months.
The primary objective is to contribute to the understanding of non-penetrating traumatic brain injury (TBI) through the description of the relationships between neuroimaging, hematological, and extensive functional/cognitive phenotyping measures. We will generate natural history data for cohort-based comparisons and to serve as the basis for future hypothesis-driven protocols. In addition, we will create and test a series of new taxonomies to describe TBI severity and predict outcome.
Three hundred adult subjects with a clinical diagnosis of non-penetrating TBI (mild, moderate and severe) will be enrolled. Subjects will be recruited from NIH, affiliated hospitals/clinics, and in the community.
This is a natural history study following a prospective cohort of subjects with a clinical diagnosis of non-penetrating acute traumatic brain injury with a cross-sectional sub-study. Subjects will be enrolled in the prospective cohort within one year of their head injury and then followed periodically for five years, with neuroimaging, including Magnetic Resonance Imaging (MRI) and Positron Emission Tomography - Computed Tomography (PET-CT), hematological, and extensive functional/cognitive phenotyping measures. Subjects will be enrolled in the cross-sectional sub-study within five years of their head injury and will be evaluated with MRI, hematological, and functional/cognitive measures within a single visit. Subjects will be stratified according to findings into cohorts for comparison. Subjects will not be treated with experimental therapies as part of the research study. This study will provide direct benefit to subjects as they will receive sensitive neuro-imaging and clinical testing that will have diagnostic value and would ordinarily not be provided to them in the community.
A variety of outcome measures will be used including MRI, to include Diffusion Tensor Imaging (DTI), Dynamic Susceptibility Contrast (DSC), and functional Magnetic Resonance Imaging (fMRI), and PET-CT. In addition, extensive and sensitive clinical phenotyping will be performed to assess functional and cognitive impairment, and quality of life assessments. Serum will also be collected and sent to a biorepository for future analysis.
