Foster care and healing from complex childhood trauma.

Children enter foster care with many forms of adversity and trauma beyond maltreatment that impact their short- and long-term physical, mental, and developmental health and their adaptation to their new care environment. Applying an understanding of the impact of toxic stress on the developing brain and body allows the health care provider to understand findings in this vulnerable population. Complex trauma alters immune response, neurodevelopment, and the genome, resulting in predictable and significant cognitive, behavioral, and physical consequences. Pediatric care of children in foster care must be trauma informed to meet their medical, mental health, and developmental needs.
