This fifth edition of the Autonomic Failure covers the many recent advances made in our understanding of the autonomic nervous system. There are numerous new chapters and extensive revisions of all other contributions. This volume makes diagnosis increasingly precise by fully evaluating the underlying anatomical and functional deficits, thereby allowing more effective treatment. It continues to provide a rational guide to aid in the recognition and management of autonomic disorders for practitioners from a variety of fields, including neurology, cardiology, geriatric medicine, diabetology, and internal medicine.
