There is a well-established association between childhood maltreatment and later poor mental health and increasing recognition that we need to find ways to support children following such experiences to improve long-term outcomes. We suggest that the rationale for such a preventive approach is directly informed by the emerging findings from the field of functional neuroimaging. Here, we review the evidence from four neurocognitive systems: threat processing, reward processing, emotion regulation and executive control. We briefly summarise what is known about each system, review the evidence that altered functioning is implicated in common mental health problems and describe how the functioning of each system is altered following maltreatment. Across domains, these neurocognitive alterations following child maltreatment are
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
