This book is designed for the neurologist who (in this day of unusually strict accountability) needs to have at hand an authoritative guide to the diagnostic criteria for all conditions that he or she may be faced with in clinical practice. While originally conceived as a compendium ofdiagnostic criteria, the author has felt the need to expand the work to include definitions of practically all terms that are used in neurology today. Historical elements are also provided--including entries of important neurologists and neurosurgeons who have impacted the field. The result is aneffective representation of the tools of the trade for the neurologist in training and a concise and precise source for the practicing neurologist. The second edition was published in 2003. Since then, advances in the definition of many neurological conditions have been made, all of which have been incorporated in the third edition. There has also been a fine tuning of the definitions and diagnostic criteria of many other conditions. The authorhas collated over 1300 articles since the last edition in order to update many of the entries. As such, the entries will have the most up-to-date definition of diseases, symptoms, diagnostic tests, and pearls of wisdom. The third edition remains an invaluable guide to the spectrum of neurologicalpractice and with nearly 7,000 references this truly is the bible of neurological terms and conditions.
