CTE Risk from Cumulative Concussive and Subconcussive Exposure

Estimate cumulative head impact exposure and CTE risk based on career length, sport, and position. Subconcussive impacts (NFL linemen: 1000-1500/season) may contribute as much as symptomatic concussions

Each component has a specific meaning:

• Career length — The career length recorded for the scenario being assessed.
• Sport — The sport recorded for the scenario being assessed.
• Position — The position recorded for the scenario being assessed.

Note: Interpret the cte exposure risk result against the thresholds and context described above.

Enter the career length, sport, position for the scenario you are assessing. Estimate cumulative head impact exposure and CTE risk based on career length, sport, and position. Subconcussive impacts (NFL linemen: 1000-1500/season) may contribute as much as symptomatic concussions. Use the cte exposure risk result to inform your calculation.
