early life adversity

The Picower Institute Spring 2023 Symposium "Environmental and Social Determinants of Child Mental Health

Studies show that abuse, neglect or trauma during childhood can lead to lifelong struggles including with mental health. Fortunately research also indicates that solutions and interventions at various stages of life can be developed to help. But even among people who remain resilient or do not experience acute stresses, a lack of opportunity early in life due to poverty or systemic racism can still constrain their ability to realize their full potential. In what ways are health and other outcomes affected by early life difficulty? What can individuals and institutions do to enhance opportunity?" "This daylong event will feature talks by neuroscientists, policy experts, physicians, educators and activists as they discuss how our experiences and biology work together to affect how our minds develop and what can be accomplished in helping people overcome early disadvantages.

Early life adversity, inflammation, and depression-onset: Results from the Teen Resilience Project

My research focuses broadly on the lifelong health disparities associated with experiences of adversity early in life. In this talk I will present the results of our recently completed Teen Resilience Project, a prospective and longitudinal study of first onset depression during adolescence. First, I will present the results on whether and how inflammatory processes may be shaped by early life adversity. Second, I will present data on the role of stress-induced inflammation in reward-related psychological processes. Finally, I will discuss the biobehavioral predictors of first-onset depression in this sample.

Brain and behavioural impacts of early life adversity

Abuse, neglect, and other forms of uncontrollable stress during childhood and early adolescence can lead to adverse outcomes later in life, including especially perturbations in the regulation of mood and emotional states, and specifically anxiety disorders and depression. However, stress experiences vary from one individual to the next, meaning that causal relationships and mechanistic accounts are often difficult to establish in humans. This interdisciplinary talk considers the value of research in experimental animals where stressor experiences can be tightly controlled and detailed investigations of molecular, cellular, and circuit-level mechanisms can be carried out. The talk will focus on the widely used repeated maternal separation procedure in rats where rat offspring are repeatedly separated from maternal care during early postnatal life. This early life stress has remarkably persistent effects on behaviour with a general recognition that maternally-deprived animals are susceptible to depressive-like phenotypes. The validity of this conclusion will be critically appraised with convergent insights from a recent longitudinal study in maternally separated rats involving translational brain imaging, transcriptomics, and behavioural assessment.
