Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| TBI Biomarker Analysis | 75-105 minutes postinjection | 18F-AV-1451 uptake will be compared in subjects with TBI and controls. |
| Relationship Between Clinical Presentation and Tau Deposition (MMSE) | 75-105 minutes postinjection | The relationship between 18F-AV-1451 uptake and clinical measures using Mini-Mental State Examination (MMSE). |
| Change in tau deposition over time | 6 months | Assess the rate of change of tau deposition as measured by 18F-AV-1451 uptake over time. |
| Relationship Between Clinical Presentation and Tau Deposition (BIS-11) | 75-105 minutes postinjection | The relationship between 18F-AV-1451 uptake and clinical measures using Barratt Impulsivity Scale 11 (BIS-11) |
