Story summary
- NFL quarterback Matt Hasselbeck joined a University study to diagnose CTE in living people.
- Lead researcher Michael Alosco is comparing former football players with patients who had no head impacts, using 10 participants in Arizona.
- Hasselbeck underwent PET scans, will donate his brain after death, and noted three concussions.
- Alosco said a living-person CTE diagnosis would enable trials and expand the study to sites, since CTE can be diagnosed post-mortem.
