Summary
The main objective of this interdisciplinary study is to develop an understanding of the molecular imaging features of blast-related mild traumatic brain injury (mTBI) in military personnel, while helping to establish assessment tools that may be of use in diagnosis, determining prognosis, and in future therapeutic clinical trials. Additionally, the objective is to evaluate feasibility of [18F]PI-2620 in the assessment TBI.Phase:

Criteria
Inclusion Criteria:1. Male
2. Right-handed
3. Age 25-54
4. Agree to participate in ALL study procedures
5. English speaking
6. Ambulatory
7. Must be able to identify a study partner who is well acquainted with the participant
for at least 2 years, to answer questions either in person or over the telephone about
the participants' activities of daily living, and to corroborate behavioral and
cognitive problems and history of brain injury
8. History of combat deployment
9. For blast-related mTBI group: must be active duty or DEERS-eligible, currently or
formerly enrolled in the 4 week intensive outpatient program at NICoE, have
experienced 1 or more blast-related mTBIs during tours of duty and report experiencing
changes in mood, behavioral or cognitive problems (blast-related mTBI considered here
and confirmed in EMR as: blast exposure from explosive device resulting in mTBI which
fits criteria defined by VA DoD mTBI guidelines which include at least one of: at time
of injury - LOC 0-30 minutes, AOC up to 24hrs, PTA 0-1 day, GCS 13-15)
10. DEERS-eligible for all participants
11. For control group 1: history of mTBI with no blast-related mTBIs (as confirmed in EMR
and/or by the BISQ and QCube) 12. For control group 2: No lifetime history of TBI (as
confirmed by the BISQ and/or EMR)
Exclusion Criteria:
1. Had a moderate or severe brain injury that required hospitalization
2. Significant systemic illness or unstable medical conditions including: uncontrolled
diabetes mellitus, uncorrected hypothyroidism or hyperthyroidism, or systemic cancer
3. Diagnosis of schizophrenia, psychosis, or other psychological disorder (Note:
blast-related mTBI group will not be excluded if they have a stable diagnosis of
post-traumatic stress disorder, depression and anxiety resulting from their military
experience; disorders existing prior to military service will serve as an exclusion)
4. Current and active alcohol or substance abuse or dependence (DSM V criteria) within
the past 6 months
5. Clinically significant laboratory test abnormalities (such as hematology, chemistry,
urinalysis, ECG) or significant impairment of liver or renal function
6. Significant cerebrovascular disease (such as TIA, stroke) or cardiovascular disease
(such as uncontrolled hypertension, atrial fibrillation)
7. Impairment of visual or auditory acuity sufficient to interfere with completion of
study procedures
8. Education level < 10 years
9. The presence of any MRI-incompatible prostheses or ferromagnetic metal, or any other
condition that would preclude ability to undergo MRI or PET (such as claustrophobia or
obesity, >350 lbs and/or unable to fit in scanners)
10. History of risk factors for torsade de pointes or take drugs known to prolong the QT
interval
11. Had 2 or more PET scans in the last year, or other significant exposure to radiation
(i.e. radiation therapy)
12. Diagnosis of neurodegenerative or neurological diseases and dementia (other than CTE)
such as Alzheimer's disease, Parkinson's disease, vascular dementia, Huntington's
disease, Pick's disease, Lewy Body Dementia, frontotemporal dementia, normal pressure
hydrocephalus, brain tumor, progressive supranuclear palsy, seizure disorder, or
multiple sclerosis
