Brief Summary
Background: \- 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. Objectives: \- 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 injury. Eligibility: \- Individuals 18 years of age and older who have had a traumatic brain injury within the past 1 year. Design:
- This study will include about eight visits to the NIH Clinical Center over 5 years. Participants will have four visits in the first year, and one visit each year for the following 4 years. Each visit will take between 1 and 4 days, and participants will be in the outpatient clinic for about 8 hours each day of the visit.
- At each study visit, participants will have some or all of the following tests:
- Medical history and physical examination
- Blood and urine tests
- Questionnaires and assessments of thinking and memory, which may be spoken aloud, written down, or entered into a computer
- Imaging scans, such as magnetic resonance imaging (MRI) or positron emission tomography/computed tomography (PET/CT).
- This study does not provide treatment and does not replace any current therapies. However, participants who are eligible for other National Institutes of Health studies may be referred to these studies by researchers.

Outcome Measures
Primary Outcomes (1)
The primary outcome measure will be to observe changes in the TBI Common Data Elements over time.
See NINDS Common Data Elements for TBI
30, 90, 180 days post injury, then annually out to 5 years.
Secondary Outcomes (1)
Changes in other clinical phenotyping measures over time
30, 90, 180 days post injury, then annually out to 5 years.
Study Arms (6)
cross-sectional TBI
Participants with a mild, moderate, or severe Traumatic Brain Injury enrolled within 5 years from injury. Seen at only one visit.
HV
Healthy Volunteer with no history of TBI
Prospective TBI
Participants with a mild, moderate, or severe Traumatic Brain Injury enrolled within 1 year from injury.
Remote Select Exposure Samples
Participants who are unable to travel to the NIH Clinical Center to participate can remote consent, answer questionnaires remotely, and have biospecimens sent to our lab for analysis.
Select Exposure Group
US government associated personnel experiencing TBI-like symptoms arising after possible exposure to a non-natural energy source
Select Exposure Matched Unaffected
a longitudinal control group comprised of unaffected volunteers matched to the Select Exposure group
Eligibility Criteria
Three hundred adult subjects with a clinical diagnosis of non-penetration TBI will be enrolled. One hundred healthy volunteers without a history of TBI will be recruited to compare outcomes to TBI participants. A select exposure group of up to 115 US government associated personnel experiencing TBI-like symptoms arising after possible exposure to a non-natural energy source will be studied. An age and sex matched cohort of non TBI healthy volunteers will be recruited for comparison (n=115). One hundred participants who are unable to travel to the NIH Clinical Center to participate but would like to participate in the study can answer questionnaires remotely, and have biospecimens sent to our lab for analysis.
You may qualify if:
- Diagnosis of non-penetrating mild, moderate, or severe TBI
- Injury occurred less than one year before enrollment
- Age 18 years of age and older
- Able to provide informed consent or with a legally-authorized representative able to provide consent
- Diagnosis of non-penetrating mild, moderate, or severe TBI
- Injury occurred less than five years before enrollment
- Age 18 years of age and older
- Able to provide informed consent or with a legally-authorized representative able to provide consent
- Age 18 and older
- Able to provide written informed consent
- Able to lie flat for up to 2 hours
- Good general medical and psychological health based on History and Physical (H\&P)
- Referral from US State Department, Department of Health and Human Services or other governmental entity based on their assessment of symptomatology and potential exposure (may include, for example, abnormal auditory sensations and subsequent oculomotor, vestibular, and cognitive symptoms)
- Age 18 years of age and older
- Able to provide informed consent or with a legally-authorized representative able to provide consent
- +6 more criteria
You may not qualify if:
- Subjects are not eligible for participation in the prospective cohort if any of the following conditions exist:
- Contraindication to MRI scanning including certain metal implants or devices such as: cardiac pacemaker, insulin infusion pump, implanted drug infusion device, cochlear, otologic, or ear implant, transdermal medication patch (Nitroglycerine) that cannot be removed for the study, body piercing(s), bone/joint pin, screw, nail, plate, wire sutures or surgical staples, shunts, cerebral aneurysms clips, shrapnel or other metal imbedded in a patient s body (such as from war wounds or accidents or previous work in metal fields or machines that may have left any metallic fragments in or near the patient s eyes).
- Multiple trauma or accidents in the past with non-certainty that metal objects are still present in the body
- Conditions precluding entry into the scanners (e.g. morbid obesity, claustrophobia, etc.).
- Pregnant women.
- Women who are breast-feeding may enroll in the study, but will not receive PET-MRI.
- Inability to read or speak enough English to complete the clinical phenotyping testing.
- Medical or Psychological instability such that the subject could not reasonably be expected to fulfill the study requirements.
- Penetrating head injury.
- Subjects are not eligible for participation in the cross-sectional sub-study if any of the following conditions exist:
- Contraindication to MRI scanning including certain metal implants or devices such as: cardiac pacemaker, insulin infusion pump, implanted drug infusion device, cochlear, otologic, or ear implant, transdermal medication patch (Nitroglycerine) that cannot be removed for the study, body piercing(s), bone/joint pin, screw, nail, plate, wire sutures or surgical staples, shunts, cerebral aneurysms clips, shrapnel or other metal imbedded in a patient s body (such as from war wounds or accidents or previous work in metal fields or machines that may have left any metallic fragments in or near the patient s eyes).
- Multiple trauma or accidents in the past with non-certainty that metal objects are still present in the body
- Conditions precluding entry into the scanners (e.g. morbid obesity, claustrophobia, etc.).
