|Brief Title ICMJE||Warfighter Head Injury Study|
|Official Title ICMJE||Warfighter Head Injury Study a Comprehensive, Multidisciplinary Research Evaluation|
This study will examine the long-term outcome of brain injuries, the effects of treatment on outcome and the effects of brain injury on people s behavior and abilities.
Men and women between 18 and 75 years of age who served in combat in the Iraq war may be eligible for this study. It will compare test results in those who sustained a traumatic penetrating or blast-related brain injury during combat with those who did not.
Participants undergo the following procedures over a 5-day period of testing that lasts about 6 hours a day:
The Warfighter Head Injury Study (WHIS) is a comprehensive, multidisciplinary research study of head-injured warfighters to be conducted at the National Institutes of Health (NIH) in Bethesda, Maryland. The goals of the WHIS include providing clinicians and scientists with new insights into the short term recovery of function following traumatic brain injury (TBI), the role of the prefrontal cortex (PFC) in executive and social functions, and to identify better predictors of short term outcome (including cognitive, neurological, and genetic factors). With the assistance of the Department of Veterans Affairs/Veterans Health Administration (VA/VHA), we propose to contact all Iraqi-Afghan (IA) warfighters with penetrating head injury (PHI), a cohort of blast injured warfighters, and a group of matched (for time in service, combat exposure, age, gender, and preinjury Armed Services Vocational Aptitude Battery [ASVAB] scores) healthy warfighter controls as well as healthy volunteers with different blast exposures (i.e.: explosives experts, artillery operators, etc ) but no documentation of brain injury. We will inquire about their willingness to participate in a comprehensive, multidisciplinary outpatient evaluation conducted at the NIH. In addition to IA warfighters, we also plan to enroll Vietnam warfighters who were included in the W. F. Caveness Vietnam Head Injury Study (VHIS) Registry, in order to conduct detailed comparisons between groups. These cohorts represent a unique opportunity for study; they were healthy and employed before injury, preinjury intelligence testing is available, and the VA/VHA permits long-term follow-up. We have previously investigated Vietnam warfighters with PHI and the published results of those studies have changed the management and evaluation of head-injured warfighters, and contributed to knowledge of brain function and the long-term effects of head injury. Furthermore, based on the knowledge acquired in our previous research with Vietnam warfighters and our current interests in the functions of the human PFC, cognitive neuroplasticity in the young brain, posttraumatic stress disorder (PTSD), posttraumatic epilepsy (PTE), caregiver stress, and genetic-plasticity relationships, we are proposing a series of new cognitive neuroscience experiments and battery of standardized neuropsychological testing to be conducted during the WHIS. In this effort, the experimental testing will be complemented with structural imaging (magnetic resonance imaging [MRI] or computed tomography [CT]), diffusion tensor and perfusion imaging, electroencephalogram (EEG), near-infrared spectroscopy (NIRS), and molecular genetics evaluations. This combination of unique patients, cutting edge cognitive neuroscience experiments and state of the art techniques will lead to new scientific knowledge and improved clinical management of warfighters with TBI.

|Eligibility Criteria ICMJE||
We will study up to 320 head-injured IA warfighters (200 PHI and 120 blast injuries), most of whom have served in Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF), and up to 500 who have been included in the VHIS Registry. PHI makes up about 20% of the total TBI from OIF and OEF.
We will ask all WHIS patients to travel to the NIH with their primary caregiver to serve as their Durable Power of Attorney (DPA) (see Section X for more information on the DPA); Caregivers will be asked to complete questionnaires and will execute a separate consent (see Caregiver Consent Form).
Inclusion of active duty military personnel is not essential to this study and can be completed without them, if necessary.
-Any medical condition that, in the judgment of investigators, would make participation detrimental to the patient (e.g.: severe clinical depression, unstable heart disease).
We will recruit 50 of the VHIS controls, 200 healthy IA warfighter control subjects, with no history of neurologic or serious psychiatric disorder or any other medical condition that would pose a risk from participation (e.g., unstable heart disease) and 120 healthy volunteers with different exposures but no documentation of brain injury. An example of this latter group would include someone who might be employed as a teacher of the proper use of explosive devices (i.e. a trainer from the Bureau of Alcohol, Tobacco and Firearms) and functions well in that position except for an occasional complaint. We will recruit up to a total of 370 normal volunteers.
We will ask all WHIS controls to travel to the NIH with a companion, some one deemed close to them in terms of relationship (i.e.spouse, child, etc.), to serve as control participants for the caregivers of warfighters. Companions will be asked to complete questionnaires and will execute a separate consent (see Caregiver/Companion Consent Form).
We will enroll caregivers and companions (i.e.: family members, domestic partners, etc.) of WHIS Warfighter participants in order to learn more about the potential burden and related issues experienced by this group.
