Many people have experienced some kind of trauma in their childhood, such as loss of a caregiver, substance abuse in the home, homelessness or abuse. There are ten types of “Adverse Childhood Experiences” that were identified in a study conducted in the 1990s. The total number of childhood traumas someone has experienced determines their ACE score. About 2/3s of the people in the groundbreaking study had at least one ACE, but the researchers also found higher rates of adult physical and mental illness associated with the amount of trauma people experienced as children.
