The traumatic stress field has adopted the term “Complex Trauma” to describe the experience of multiple and/or chronic and prolonged, developmentally adverse traumatic events, most often of an interpersonal nature (e.g., sexual or physical abuse, war, community violence) and early-life onset. These exposures often occur within the child’s caregiving system and include physical, emotional, and educational neglect and child maltreatment beginning in early childhood- Developmental Trauma Disorder
