In the second section, composed of five chapters, Munro provides a comprehensive clinical description of delusional disorder and its somatic, jealousy, erotomanic, persecutory, and grandiose subtypes. The author notes the fundamental similarity in the form of psychopathology between the different types of delusional disorders, which differ in their content. Although the author provides a lucid description of these different delusional disorders (richly supplemented by case material), he provides a scant discussion of how to delimit delusional disorder, somatic type, from psychotic depression and delusional disorder, grandiose type, from psychotic mania. In fact, throughout the book, the author extensively discusses differences between schizophrenia and delusional disorders but is rather frugal when it comes to considering the distinction between delusional disorders and psychotic mood disorders. In view of the "affective bias" that has guided our diagnostic approach since the 1980s, a substantial proportion of the conditions that the author would consider delusional disorder are currently being diagnosed as psychotic mood disorders; this discussion would have been useful. There could also have been some discussion of the sociocultural determinants of delusional content.
