Maternal depression around childbirth has potentially large and long-lasting effects on child development. While psychological interventions are effective at reducing severity of perinatal depression, the pathways by which these interventions may impact child development are not well understood. In this study, we focus on measuring stress pathways, particularly chronic activation
of the hypothalamic-pituitary-adrenal (HPA) axis, which is hypothesized to be involved in both depression and infant brain development Our results indicate that treating even mild cases of depression can result in objective and measurable physiological changes, which could translate into changes in decision-making. Additionally, our results suggest that DHEA may
be a robust marker of cognitive development at these younger ages. Lastly, using exceptionally rich data on parenting inputs throughout infancy, we explore whether impacts on infant DHEA levels are mediated by early parental investment.
