NCT02079766

Brief Summary

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.
