Purpose of review: Concussion, or mild traumatic brain injury (mTBI), represents the majority of pediatric Emergency Department (ED) presentations of TBI. While most children and adolescents will recover within 4 weeks of injury, approximately one third will continue to experience persisting symptoms. This review aimed to provide an overview of literature from the past 5 years examining predictors of recovery in the ED.
Recent findings: Predictors could be characterized into three categories; (i) cognition, (ii) proteomics, and (iii) pre-injury/injury-related factors. There is preliminary support for the use of computerized neuropsychological testing. The prognostic use of proteomics is a promising area of future research. Pre-injury and injury-related characteristics have been thoroughly examined and developed into a clinical risk score for predicting delayed recovery. Substantial progress has been made in identifying risk factors for delayed recovery at ED presentation. The current evidence provides a platform for additional research that can refine and validate these predictors.
