Researchers at Penn State Medical Center (PA, USA) have demonstrated that salivary miRNA improves identification of prolonged concussion symptoms in children and young adults compared with a standard survey. The results could lead to improved concussion management.
Symptoms of concussion following mild traumatic brain injury (mTBI) usually end within 2 weeks; however, prolonged symptoms occur in approximately one-third of children. Currently, diagnosis and assessment relies on symptom reporting, a measure that does not always correlate with objective injury measures.
