Book excerpt: Traumatic Experience and the Brain is the result of Dr. Dave Ziegler's three decades of experience with children traumatized by abuse and/or neglect. Containing almost 100 pages of new material, this newly revised and updated second edition details the effect of trauma on the developing brain, describing how it actually rewires one's perceptions of self, others, and the world. It is a book of hope for foster, natural, and adoptive parents of such "broken" children and the therapists, teachers and social workers who attempt to help them. Dave Ziegler, M.S., Ph.D., is the director of Jasper Mountain, a residential treatment program in Oregon for some of society's most damaged children.
