Book Review by: Nano Khilnani
There are many reasons why patients with psychogenic movement disorders and other conversion disorders “are falling through the cracks” (meaning they have not been able to receive the correct treatment), the editors of this book point out. Here are some of the reasons:
- Paucity of research and evidence-based reports on the mechanisms of treatment
- Many movement disorders have a psychological basis, but patients are not referred to psychologists; much less to psychiatrists
- There are various obstacles to accessing appropriate, competent psychiatric care
“ Such patients utilize a large fraction of healthcare resources, estimated at 16 percent of dollars in the USA,” the editors write in their Preface. This quoted portion is not quite clear to us.
Nevertheless, because many of those people with psychogenic movement disorders and other conversion disorders are not receiving the right treatment because of the reasons we cite above, we decided to provide as much information as we can on these disorders through this book.
One way to do this is to list all the 43 chapters of this book here so that those who are reading this review will be able to get all the details necessary to understand the symptoms and develop the right course of treatment for those afflicted with such disorders.
Seventy-eight specialists in brain cognition, clinical psychology, motor control, neurology, neuropsychiatry, neuroscience, neurosurgery, Parkinson’s Disease, psychiatry, psychobiology, psychology, radiology, social behavior, and related areas, authored the chapters of this extensive study on psychogenic movement disorders and other types of disorders.
They are from all over the United States and nine other countries – Australia, Canada, Germany, Italy, the Netherlands, New Zealand, Switzerland, Turkey and the United Kingdom.
We list below the titles of the 43 chapters of this book and the four Sections around which they are organized, to provide you an overview of the contents:
- Section I – Clinical Issues
- Introduction to the psychiatry of conversion disorders

Appendix: Psychogenic movement disorders video legends
A meeting of physicians, psychologists, psychiatrists, and other healthcare professionals who study and treat patients with psychogenic movement and similar ailments, conditions, and diseases was held about ten years ago in Washington DC.
This book contains much of the subject matter of the discussions and outcome of that gathering entitled Second International Conference on Psychogenic Movement Disorders and Other Conversion Disorders sponsored by the Movement Disorder Society and other organizations involved in the study and treatment of people afflicted with these disorders.
There are many incorrect assumptions and beliefs in the medical community about the cause-and-effect relationships between psychogenic movement disorders (and other disorders) on the one hand, and the existence of a psychological basis for those disorders, on the other hand.
This work sheds light on these assumptions and provides empirical evidence of what has been found so far, or not found.
