Book excerpt: Explains the neurological, emotional, and behavioral impacts of violence and trauma experienced by newborns, infants, children, and teenagers. 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. Explains the effects of a range of types of violence and trauma, including child abuse, sexual abuse, family violence, teen dating violence, loss of parent or caregiver, exposure to natural disaster, and more Addresses the impacts of violence and trauma during infancy and early childhood, middle childhood, and adolescence Details mental health interventions to encourage resilience and posttraumatic growth Describes how public systems from schools to pediatric and obstetrical clinics to juvenile justice systems identify and work with children affected by violence and trauma
