Paediatric post‐traumatic stress disorder (PTSD) is an incredibly heterogeneous and syndromic disorder that likely has a myriad of underlying neurobiological mechanisms at play. The disorder is even more complicated in youth, given that the expression of illness interacts with ongoing developmental processes. In their review in this issue, Weems and colleagues call for broader network‐based approaches for studying the development and expression of PTSD in youth. In this commentary, I highlight some of the important knowledge gaps raised by Weems et al. and propose ways in which future studies may leverage network‐based approaches for eventual translation into clinical care. Key concepts include the use of network‐based approaches for understanding the emergence and maintenance of PTSD symptom architecture over development, identification of resilient and vulnerable patterns of symptom and brain network architecture following trauma, and consideration of how divergence between biological (e.g. brain) and chronological may inform our understanding of resilient and vulnerable patterns over development. Importantly, advancing and translating this work to clinical care will require larger, prospective studies assessing youth as early in development as possible, and integrating information across multiple research groups and sites.
