After concussion, biomarkers in blood may help predict recovery time
A study of high school and college football players suggests that biomarkers in the blood may have potential use in identifying which players are more likely to need a longer recovery time after concussion, according to a study published in the July 3 online issue of Neurology®, the medical journal of the American Academy of Neurology.
"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," said study author Dr. Timothy B. Meier of the Medical College of Wisconsin in Milwaukee and a member of the American Academy of Neurology.
The study involved 41 high school and college 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. Those who had concussions had blood tests within six hours after the injury, then again 24 to 48 hours later and also eight, 15 and 45 days later. Those who did not have concussions had tests at similar times for comparison.
The tests looked at levels of seven biomarkers for inflammation that have been related to more severe brain injury.
Of the seven biomarkers, two were elevated for those with concussion at six hours after the injury compared to the athletes with no concussion.
"Eventually, these results may help us better understand the relationship between injury and inflammation and potentially lead to new treatments," Meier said.
