A revised and updated edition of the bestselling guide to understanding borderline personality disorder. 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. Both pharmacological and psychotherapeutic advancements point to real hope for success in the treatment and understanding of BPD. 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.
