Traumatic events known as adverse childhood experiences (ACEs) can affect children physically, mentally, and emotionally, sometimes with long-term health and behavioral effects. Abuse, neglect, exposure to community and domestic violence, and household dysfunction all have the potential to alter brain development and behavior, but few people are able to recognize or respond to trauma in children. Given the prevalence of childhood exposure to violence-with one in four children ages 5 to 15 living in households with only moderate levels of safety and nurturance and infants and children ages 0 to 3 comprising the highest percentage of those maltreated-it is imperative that students and professionals alike be able to identify types and consequences of violence and trauma. This book provides readers with the information they need in order to know how to detect and prevent ACEs and to help children who have lived through them.
