George Mason researchers think saliva might unlock concussions

Researchers have tried to diagnose concussions with cognitive tests, eyesight tests and balance tests. But would you believe a spit test?

The Fairfax County (Va.) Times reported on two researchers who are exploring a new way of diagnosing concussions -- by using saliva.

The George Mason professors are comparing the preseason samples to the samples from kids who suffered head injuries. They think the change in saliva proteins after a concussion opens a door that no one has looked into before.

They have used their research so far to apply for a grant through the Head Health Challenge, a combined effort of the NFL and General Electric.
