This book is certainly outstanding and it the only book besides _Shadow Syndromes_ which clearly confronts the topic of the relationship between Autism Spectrum Conditions (particularly Asperger's Disorder) and the Schizoid Personality. While some researchers have proclaimed the two to be separate diagnoses (e.g., Tantam), Wolff proceeds to give a detailed account of a group of children who were labeled 'Schizoid Personality of Childhood.' Furthermore, she extensively reviews the psychiatric literature in examining such children previous to Hans Asperger's account of Autistic Personality Disorder of Childhood, overviewing the evolution of the Schizoid Personality diagnosis. Wolff especially stresses the inadequacy of the current Asperger's diagnostic criteria because it often fails to include minimally impaired/gifted 'Schizoids'. Finally, Wolff expresses her conclusion: the majority of her Schizoid children, although many do fit the current DSM-IV/ICD-10 diagnostic criteria for Schizoid Personality Disorder, would be more appropriately accounted for as having mild Asperger's Syndrome with some Schizotypal traits; also, although there was some overlap between High-Functioning Autistic children and the Asperger/Schizoid children, a distinction was made between the two groups.
