Revised, updated, and expanded by nearly one-quarter, Brain's Diseases of the Nervous System remains an essential reference work for neurologists, neurosurgeons, and other practitioners. It is also the most comprehensive and up-to-date single-volume textbook of neurological sciences currently available. In addition to many new illustrations, new sections have been added on neuroimunology; investigative techniques such as computerized tomography, positron emission tomography, and nuclear magnetic resonance; and other topics. The introductory chapter on pathophysiology has been completely rewritten.
