MicroRNAs (miRNAs) may serve as biomarkers of concussion with prolonged symptoms, according to results of a prospective cohort study published online November 20 in JAMA Pediatrics.
More than 80% of concussions follow mild traumatic brain injuries (mTBIs). For one-third of children, symptoms of concussion persist beyond 2 weeks. A tool to predict children at elevated risk for prolonged concussion symptoms (PCS), other than questionnaires to identify clinical risk scores, would be valuable in referring appropriate patients to specialists.
