The Dictionary of Neurological Signs can be almost as well described in terms of what the book is not, along with details about what it is. The Dictionary is not a handbook for treatment of neuropathies. While many entries provide the latest treatment options, up-to-the-minute therapies are not discussed in bedside level detail. The Dictionary is not a board review book because it is not in Q&A format but could easily serve in that capacity since each entry is a fairly complete snapshot of a specific disorder or disease. The Dictionary is an alphabetical listing of commonly presenting neurological diseases and disorders designed to guide the physician toward the correct clinical diagnosis. The content is focused, problem-based, concise and practical. The structured entries in this practical, clinical resource provide a thumbnail of a wide range of neurological signs. Each entry includes: • definition of the sign • a brief account of the clinical technique required to elicit the sign • description of the other signs which may accompany the index sign • explanation of pathyophysiological and/or pharmacological background • differential diagnosis • brief treatment details. Where known, the entries also include neuroanatomical basis of the sign. TheDictionary provides practical, concise answers to complex clinical questions.
