In a previous study of mTBI, we found that mTBI was associated with a significantly increased risk of having subsequent affective disorders. These disorders were most prominent during the first 12 months (23% following mTBI and 14% in the control group). [Delmonico RL, Theodore BR, Sandel ME, Armstrong MA, Camicia M. Prevalence of depression and anxiety disorders following mild traumatic brain injury. PM&R. 2022 Jul;14(7):753-763. doi: 10.1002/pmrj.1265]). In our previous study, 42% of patients with an mTBI diagnosis were under 18. We made it a priority to investigate the pediatric population as our next step in our research. From an extensive review of the literature, it was clear that the predominant mental health disorders in children and adolescents were affective disorders (depressive, anxiety, and adjustment disorders) and behavioral disorders (oppositional defiant disorder (ODD), attention deficit hyperactivity disorder (ADHD), and conduct disorder.
