Publication date: Available online 18 December 2019Source: International Review of NeurobiologyAuthor(s): Alexander J. Dufford, Pilyoung Kim, Gary W. EvansAbstractExperiencing poverty in childhood has been associated with increased risk for physical and mental health difficulties later in life. An emerging body of evidence suggests that brain development may be one mediator of this relation. In this chapter, we discuss evidence for an association between childhood poverty and brain structure/function. First, we examine the association from a lifespan perspective discussing studies at multiple developmental stages from the prenatal period to late adulthood. Second, we examine existing studies that link childhood poverty, brain development, and physical and mental health outcomes. Third, we discuss studies linking childhood poverty and environmental risks and protective factors. Lastly, we discuss suggestions for future studies including advances in network neuroscience, population neuroscience, using multiple imaging modalities, and the use of longitudinal neuroimaging studies. Overall, associations between childhood poverty, brain development, and development over the life course may help to both better understand and eventually reveal salient intervention strategies to mitigate social disparities in health.
