Presidential Symposium 2 Opening Session: MINDING OUR MICROBES: EXAMINING THE ROLE OF THE GUT MICROBIOME IN DEVELOPMENTAL PSYCHOPATHOLOGY
The gut microbiome has been trans-diagnostically linked with psychopathology in adults, and a wave of recent research has suggested that differences in the diversity and composition of the gut microbiome in early life may be associated with differential risk for the development of psychopathology. The gut microbiome undergoes a critical period of development in early life, overlapping with sensitive periods in other key physiological and stress response systems, making questions about connections between the gut microbiome and psychopathology particularly important to consider from a developmental perspective. In this symposium, we explore the role of the gut microbiome in developmental psychopathology, the state of the literature in this growing line of inquiry, and identify areas for future research. In the first presentation, Dr. Sarah Vogel will present longitudinal associations between development of the gut microbiome throughout infancy and behavioral measures of fearfulness and negative affectivity in early childhood. Next, Dr. Patricia Brennan will integrate perspectives from the social determinants of health and developmental origins of health and disease (DOHaD) frameworks to discuss connections between prenatal stress, the infant gut microbiome, and child behavior problems in two samples of African American infants and their mothers. Naomi Gancz will then discuss connections between the gut microbiome and internalizing symptoms across childhood and the role of childhood adversity in moderating gut-behavior associations. Finally, Dr. Harikesh Dubey will present some experimental work examining the effects of fecal transplant procedures in mice and implications for anxiolytic behavior, with an emphasis on neural mechanisms, including myelination and dendritic complexity. This symposium will integrate research perspectives from across disciplines, species, domains, and developmental timing to contextualize the state of our scientific understanding of the role of the gut microbiome in developmental psychopathology and inspire discussion about the potential future directions for research and intervention.
