Traumatic Brain Injury (TBI) is among the most common reason that children visit the Emergency Department, with approximately 50,000 visits every year in Canada. Within the pediatric group, young children aged 0-4 years and adolescents aged 15-19 years are most likely to sustain a TBI.

A critical decision confronting health care providers is how to predict in the acute setting which children will suffer persistent postconcussive symptoms (PCS) and functional impairments after mild traumatic brain injury (TBI).
