And yet, this is a volume with many virtues. Although perhaps less important than content, the book’s format is more inviting than is true of many current publications. It is printed on good paper, there are wide margins, and the print is easy to read. Chapters have clear and descriptive subheadings and end with a summary or concluding paragraph that in many instances is worth reading as an initial orientation to the chapter. Many chapters also have unusually clear, detailed, and very useful tables. These include checklists for assessing cognitive function, causes of various disorders, detailed diagnostic criteria, factors to consider in differential diagnosis, and summaries of studies relevant to particular issues. One major annoyance, forming an unwelcome memory test for the reader, is the veritable alphabet soup of acronyms used throughout for diagnostic conditions, clinical tests, neurotransmitters, medications, etc., which are often pages removed from their definitions and do not appear in the index. Any future editions would be helped by an alphabetic glossary of these.
