Among older children, neglect is linked to reduced cortical grey matter volume, whereas abuse is linked to reduced right amygdala volume. Less is known about whether similar effects of adversity are evident in infancy, a period of particularly rapid brain growth. This study evaluated whether family involvement with child protective services (CPS) was linked to differences in infant brain volumes (whole brain grey matter, cortical grey matter, right and left insular cortex, and right and left amygdala). Participants were recruited in the northeastern United States. Mothers (N = 55) reported on any family involvement with CPS as a parent. Infants completed a brain MRI between 4 and 25 months of age (Mage = 11.56 months). Family CPS involvement was associated with lower infant whole brain grey matter volume, cortical grey matter volume, and left insular cortex volume. No relations to amygdala volumes were observed. Caregiving adversity may affect cortical grey matter development during infancy, with family CPS involvement as an accessible index identifying infants at risk.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
