Early Adversity, Neurodevelopment, and Risk for Psychopathology
The overarching goal of this line of work has been to investigate how early life stress shapes children’s neurodevelopment and contributes to maladjustment, with particular attention to identifying sensitive periods in development. To achieve this aim, I included a neuroimaging assessment (which included structural MRI, task-based fMRI, resting state functional connectivity, and diffusion tensor imaging) in a longitudinal study investigating the role of early life experiences and stress physiology on risk for future psychiatric problems in the high-risk offspring of depressed parents. This study assessed multiple aspects of the early rearing environment (e.g., observations
observations of parenting, interview-based measures of exposure to parental depression and family and child stress) and child and parent stress physiology (salivary cortisol levels in response to stress and across the day); our multi-method approach aimed to characterize comprehensively the child’s environment and stress physiology across the early childhood and school-age periods. Our findings show important age-dependent effects in the relations between the early environment and brain development.
