Blood tests might be able to tell how badly a concussion has rung a person's bell, a new study says.
Certain brain-related biomarkers in the blood are associated with how bad a teenager's symptoms will be as they recover from a concussion, researchers reported in the November/December issue of the Journal of Head Trauma Rehabilitation.
There are also some significant differences between male and female concussion patients in terms of the markers found in their blood, researchers added.
"Our study builds on previous research suggesting that some brain-related markers may provide objective measures of brain injury in teens with concussion," said lead researcher Mia Pasini, a doctoral student at Johns Hopkins University in Baltimore.
