Outcome Measures
Primary Outcomes (2)
Flortaucipir Visual Read as CTE Biomarker
Flortaucipir uptake was rated visually by sponsor expert reader as 'No Uptake', 'Mild Uptake', 'Moderate Uptake', or 'Intense Uptake'.
Baseline scan
Relationship Between Clinical Presentation and Tau Deposition (Subjects at High Risk of CTE Only)
The relationship between flortaucipir uptake and clinical presentation, as measured by the Mini-Mental State Examination (MMSE). Mini-mental status exam is a 30-point questionnaire that is used to measure cognitive impairment. Scores range from 0 to 30 with lower scores representing greater levels of cognitive impairment. Specified in statistical analysis plan to only be conducted in High Risk of CTE group.

Control
EXPERIMENTALFlortaucipir PET scans in former non-contact athletes
