Biological Origin of Depression: Evidence from Infant Brain Imaging and Genetics
Qiu Anqi

Synopsis

According to the fetal-programming model, exposure to stressful or hostile conditions in utero is associated with compromised development and a lifelong risk of adverse health outcomes. In this talk, I will give an overview on our longitudinal cohort study, Growth Up in Singapore Towards Healthy Outcomes (GUSTO). I will then show the first evidence revealing antenatal depression influences on brain anatomy and function and genetic modulation on such influences. Our findings suggest that an increased risk for anxiety and depression may be transmitted from mother to child during fetal life and that the effect is dependent upon infant genotypes.
