Brain Metabolite Patterns in Early Mild Traumatic Brain Injury Predict Post-Concussion Syndrome Development
This study used magnetic resonance spectroscopy within 72 hours of mild TBI to measure brain metabolites (NAA, creatinine, choline) in specific brain regions and assessed their ability to predict post-concussion syndrome at 6-month follow-up. Early metabolite patterns in the anterior cingulate cortex, particularly NAA/choline ratios, were identified as significant predictors of both PCS occurrence and severity, suggesting neurochemical markers may help identify which patients develop prolonged symptoms.
