Best thing about Treating Attachment Disorders is the considerable Clinical Case examples (around three-fifths of the book) covering initial presentation, patient history, consideration of attachment dynamics, therapy and course and follow-up. Furthermore Brisch looks at attachment issues coming to the forefront for people from pregnancy through to old-age - where attachment through the lifespan is rarely looked at. He also looks at areas of society where attachment issues need to, or could be considered to assist individuals, such as schools.
I found the writing in the first part of the book, which covered theory and typology and diagnosis of attachment disorders, drier than other books I've read on the subject, but there was information or conceptualization of this material that was new to me which made up from it. I also appreciated the organization and overall the succinctness of material presented, and clarity and simplicity of writing. Brisch also makes use of the concepts and diagnostic labels in the field, yet somehow I get the sense he holds these in a light and flexible way, maintaining some deeper understanding of individuals suffering.
Brisch connects attachment difficulties to a range of symptom presentations and disorders, reflective of his stance that attachment is a "fundamental human motivation" (which I agree), and which more importantly is always present and operating in the therapeutic relationship (definitely). In noting the importance of attachment in therapy, I would have liked, in the clinical case examples, more information on his countertransference experience with some of his patients - he certainly names some of his responses, but does not go into them.
Treating Attachment Disorders is a book I'd go back to, to refresh my perspective and remind myself of the central importance of attachment issues in therapy, regardless of presentation.
