Editors Storch and McKay offer this volume on the delineation, assessment, and treatment of obsessive-compulsive spectrum disorders. The introduction explicitly addresses scope and definitions with an acknowledgement of controversy and the various approaches generating it. The first half of the book contrasts obsessive-compulsive behaviors and treatment approaches at different developmental stages, and discusses a number of specific symptom presentations including hoarding disorder, body dysmorphic disorder, body-focused repetitive behaviors, Tourette’s, and health anxiety. Part II addresses the common comorbidities of depression, self-injury, and autism, while part III presents two chapters on pharmacological treatment focusing separately on adolescents and adults. The final section presents neuroscientific findings on the OC spectrum garnered from twin studies and functional neuroimaging. Annotation ©2014 Ringgold, Inc., Portland, OR (protoview.com)
