Concussion could be screened for using a blood test, scientists say after discovering two blood biomarkers commonly elevated in injured sports players.
The small study on 43 high school and college football players in the US suggests that doctors could screen for the specific biomarkers to identify which players need a time out.
Levels - Players - Blow - Head - Researchers
Depending on the levels, they may even be able to predict which players will take longer to recover following a blow to the head, the researchers at the Medical College of Wisconsin say in a new study.
Though the cohort is small, the findings are hailed as a key step forward in the race to better diagnose and treat head-hits amid growing evidence that contact sports are linked to brain diseases.
'With - People - Concussions - Number - Symptoms
'With so many people sustaining concussions and a sizeable number of them having prolonged symptoms and recovery, any tools we can develop to help determine who would be at greater risk of problems would be very beneficial, so these results are a crucial first step,' study author Dr Timothy Meier said.
The study, published online by the journal Neurology, involved 41 high school and college American football players who experienced a concussion during the season. None of the players lost consciousness with their concussions.

The players were matched with 43 football players of the same level, age and position who did not have a concussion during that season. All of the participants had blood tests at the beginning of the season.
