This book begins with epilepsy, the paradigmatic disorder of behavioral neurology. The chapter serves as a model for the layout of the other chapters. It is clinically oriented, and it provides an initial description of the condition, followed by treatments, followed by comorbid behavioral disorders. It includes discussions about etiology and pathogenesis and relationships between the neurological disorder and the behavioral problems. The text is not overreferenced, and a number of older references are retained, essentially as a reminder of earlier editions. However, more recent references that support or refute the conclusion are also included (not overdone). Obviously, the more recent references contain information from up-to-date neuroscience, in particular theories that relate to neurochemistry and neuroimaging, which the first edition of this book could hardly have anticipated.
