Disruptions in brain metabolites following concussion are commonly reported in the literature. These studies often have different timings following injury, are limited to adults and have limited sample size. Using magnetic resonance spectroscopy (MRS), we show in the largest MRS in pediatric concussion study to date, that there are no group differences in metabolites between concussion and orthopedic injury at acute injury. Glx was associated with cognitive symptoms but no other metabolites showed a relationship with symptoms. No difference between groups may indicate that metabolic disturbance following injury may be a broad indicator of injury or alterations are regionally specific.
