After more than two decades as the essential guide to Borderline Personality Disorder (BPD), this new edition now reflects the most up- to-date research that has opened doors to the neurobiological, genetic, and developmental roots of the disorder as well as connections between BPD and substance abuse, sexual abuse, Post-Traumatic Stress Syndrome, ADHD, and eating disorders. This expanded and revised edition remains as accessible and useful as its predecessor and will reestablish this book as the go-to source for those diagnosed with BPD, their family, friends, and colleagues, as well as professionals and students in the field.
