Psychiatric disorders contribute to substantial morbidity and mortality among young people. While the majority of clinical diagnoses are still being made in adolescence and young adulthood,1 underlying susceptibility or vulnerability factors are increasingly being recognized in early life-some as early as infancy. Identifying such factors in children in early stages of development offers an opportunity to intervene and potentially prevent later development of psychiatric disorders. Further, leveraging neuroimaging data associated with early developmental trajectories will improve our understanding of the complex interplay between neurobiological variation and psychiatric morbidity.
