Among today’s astounding research discoveries, perhaps the most fascinating is the mapping of the human genome and its implications for a vastly improved understanding of how genes affect our physiology and behavior. With that understanding comes a critical need to establish a diagnostic taxonomy for psychiatric illness that is more precise but still clinically relevant.

This volume responds to that need. It highlights the shortcomings of current categorical diagnoses, such as those used in DSM-IV, for future research needs in behavioral disorders in general and psychiatric genetics in particular.

With a chapter by each distinguished neuroscientist who presented at the 2000 American Psychopathological Association (APPA) meeting, this volume is divided into four sections: Definitional Tensions, which discusses the difficulties with the current categorical diagnostic system; Imaging Psychopathology, which presents research demonstrating how imaging technologies can tremendously improve our illness definitions; Longitudinal Studies, which details what we can learn from epidemiological and other longitudinal studies; and Exploring Alternatives, which discusses the application of dimensional classification systems in genetics research in psychopathology, with a fascinating chapter on using new methodologies for treating subsyndromal or pre-schizophrenia, a taxonomic condition defined herein as “schizotaxia.”

This unique collection represents a significant step in developing approaches to classification that will lead to more accurate diagnoses and treatments for patients and a broader range of taxonomic options for researchers. As such, it will also be welcomed by psychiatric clinicians and educators, as well as by anyone interested in genetics and how it governs human behavior.

The 21st century will see the rise of molecular medicine. For psychiatry to participate in this ongoing revolution, we need a diagnostic system that is biologically and genetically meaningful. The chapters in this volume offer a wide-ranging blueprint to establish a diagnostic system that is relevant to both treatment and research.—Richard D. Todd, Ph.D., M.D., Departments of Psychiatry and Genetics, Washington University School of Medicine, St. Louis, Missouri

Defining Psychopathology in the 21st Century is a fascinating collection of papers, and represents some of the best research being done in current psychiatry.—Metapsychology Online, 8/1/2003

[Helzer and Hudziac] have produced a fine text that is both scholarly in content and exciting to read.—British Journal of Psychiatry, 8/1/2003
