Attention-Deficit/Hyperactivity Disorder Following Mild Traumatic Brain Injury in Children: A Retrospective Exploratory Study

This retrospective cohort study of 86 pediatric patients investigated whether secondary ADHD (S-ADHD) develops after mild traumatic brain injury, comparing 10 patients who developed new ADHD diagnoses with 76 who did not. While no acute clinical features at baseline predicted S-ADHD development, children with secondary ADHD required significantly longer follow-up monitoring (median 536 vs. 132 days), suggesting prolonged clinical oversight is important in this population.
