Primary Outcome Measures:
  • CTE Biomarker Analysis [ Time Frame: Up to 100 minutes post injection ] [ Designated as safety issue: No ]
    18F-AV-1451 uptake and florbetapir F 18 standard uptake value ratio (SUVR) will be compared in subjects with a high risk of CTE and controls.

  • Relationship Between Clinical Presentation and Tau Deposition [ Time Frame: Up to 100 minutes post injection ] [ Designated as safety issue: No ]
    The relationship among 18F-AV-1451 uptake, florbetapir SUVR, and measurements including neuropsychological assessment battery (NAB) List and Story Learning tests, Trail Making Test - Parts A and B, Wisconsin Card Sorting Test, Wechsler Adult Intelligence Scale - Revised (WAIS-R), Animal Fluency, NAB Naming Test, NAB Map Reading Test and Mini-Mental State Examination (MMSE).
