Zou R, et al. - Researchers examined how child brain development, including volumetrics and white matter microstructure is linked to exposure to maternal depressive symptoms at various developmental stages from fetal life to preadolescence. From a longitudinal birth cohort in Rotterdam, the Netherlands, participants were 3,469 mother-child pairs with data on maternal depressive symptoms and child neuroimaging at age 10. Findings revealed a consistent association of perinatal maternal depressive symptoms with child brain development evaluated 10 years later. Results thereby indicate that for adversities such as maternal depressive symptoms, the postnatal period is a period of vulnerability.
