This well-organized volume begins with basic reviews of animal and human research on vulnerability and resilience, neurophysiology, and endocrine concomitants of loss and trauma. Chapters on sudden unexpected trauma cover the effects on children of natural disasters (e.g., hurricanes), man-made disasters (e.g., a plane crash), and deliberate assaults on children (e.g., killings in school settings). Several contributors review the literature on stress and medical illness, including asthma, the immune system, childhood cancer, and juvenile diabetes. Ensuing chapters expound on suicide among youth, including its effect on peers, siblings, and other family members. Next, in a section on psychiatric disorders associated with parental neglect and abuse, the controversial issues of memory and dissociation receive a balanced treatment, with findings grounded in clinical observation, animal studies, and innovative human studies of early memory. A final section examines the interaction between normal child development and trauma, adoption, divorce and remarriage, and death of a parent.
