Sure, I agree, you definitely want to detect the more subtle cases. Thing is, I doubt a saliva test would ever replace the "Well, he just asked the entire opposing team to marry him and told us he can see the future"[1] detection of concussion, or all the other known symptoms of concussions that referees at the club levels, and team doctors at the professional levels are trained to notice. So yeah, if this can detect concussions not detectable via current methods, it's a definite win. But I also agree that if it were to replace the existing techniques, it'd be a net loss. But I believe that, ultimately, the administrators of these sports realise a bunch of brain damaged former players is bad for the sport, so they will use it in a manner that complements, not replaces, existing diagnostic techniques. [1]: Pretty much how my last concussion went down (thanks rugby league), except it was my teacher and half of my class I asked to marry me before they sent to me the sick bay. The delusions of predicting the future were very much real. |
