This new edition of the Essentials of Neuropsychiatry and Behavioral Neurosciences reflects the significant revisions in the 5th edition of The American Psychiatric Publishing Textbook of Neuropsychiatry and Behavioral Neurosciences, published in 2008. Like its predecessor, this volume distills the critical information presented in exhaustive detail in the Textbook to create an accessible, comprehensible, and portable resource for front-line clinicians and psychiatry and neurology residents preparing for the formidable American Board of Psychiatry and Neurology certification examination. Abridged, yet undiminished in its utility, the book functions as a subspecialty reference that details assessment techniques and the full range of treatment options for patients with neuropsychiatric disorders. A concise opening chapter on Fundamentals of Cellular Neurobiology provides the reader with the scientific framework necessary to understand fully and contextualize the chapters on specific disorders and treatments that follow. Essentials of Neuropsychiatry and Behavioral Neurosciences is an efficient yet comprehensive learning tool for both the basics and the advanced techniques on the leading edge of this swiftly expanding field.
