Amazon.com description: Product Description: The incessant stream of new data generated by the considerable acceleration in research devoted to the motor system disorders in the last decade is decidedly reflected in this book. The ordinate angle forming the abscissa of the volume is not a narrow one, expounding on topics from peripheral to central motor disease, and on the medical side from diagnosis to treatment. New features of the book include an updated WFN classification of motor neurone disorders. Where possible, disorders have been given 6-digit identification numbers as listed in McKusick's (1990) catalogue. This volume further equals the excellence for which theHandbook of Clinical Neurology has for years been renowned, and divergence from the previous volume is a direct reflection of how new volumes in this series stay in the forefront of neurological developments, pointing out the day when treatment of these disorders will not be alleviative or palliative, but preventive.
