(WHDH) — A new study suggests that saliva could one day be able to diagnose a concussion in children, teens and young adults.
Researchers at Pennsylvania State University say five molecules found in saliva have the potential to identify symptoms of a concussion.
They believe the molecules could also determine how long a concussion may last.
Doctors say most concussions are suffered by kids and teens.
Symptoms can last for two weeks or longer.
A biotech company hopes to have a concussion text available within two years.
