Book excerpt: Better understand your patients' complete medical profile and provide the best possible care! This one-of-a-kind reference provides a practical look at neurological disease and how it affects, and is affected by, other disease. It helps neurologists manage patients with co-existing medical conditions, and helps internists understand and treat the neurological manifestations of patients' primary diseases. A new emphasis on diagnosis and management-including advances in pharmacology, genetic-based therapies, and new imaging techniques-makes this 4th Edition more clinically valuable than ever! Focused content highlights the vital links between neurology and other medical specialties, promoting a better understanding of all disciplines, as well as enhancing patient care. Comprehensive coverage of advances in pharmacology, such as new antibiotics for infectious diseases, helps you successfully manage a full range of diseases and disorders. An interdisciplinary team of authors provides insight into the neurological aspects of the conditions you see in daily practice. Easy-to-read chapters apply equally well to neurologists and non-neurologists, providing essential knowledge that covers the full spectrum of medical care. Expanded chapters emphasize key diagnostic and therapeutic information, including appropriate testing and treatments for neurological disease. An emphasis on advances in pharmacology and new imaging techniques helps you better manage your patients and understand how new drugs or therapies will affect your patients and practice. New chapters on auditory and vestibular disease, ocular disease, and cutaneous disease provide a well-rounded look at the specialty.
