For more than three decades, the Textbook of Neuropsychiatry and Clinical Neurosciences has been the gold standard for understanding the structural and functional foundations and rapidly evolving knowledge base of neuropsychiatric disorders. In the new edition, the esteemed editors have undertaken a complete reorganization, reconceptualizing the way the material is presented and integrating considerations of neuropsychiatric symptoms, syndromes, and treatments into chapters addressing the neuropsychiatry of neurodevelopmental disorders, acquired neurological conditions, neurodegenerative disorders, and primary psychiatric disorders. The result is a text that flows easily and logically from general principles to specific diagnostic tools and conditions, making it a clinically relevant and eminently practical guide for medical students and residents, psychiatrists, neurologists, psychologists and neuropsychologists, as well as a broad range of professionals who work in diverse clinical settings (e.g., the general hospital setting, physical medicine/rehabilitation hospitals, psychiatric institutes, community mental health centers, alcohol and chemical dependency programs, and outpatient services and doctors' offices).The book possesses a multitude of useful attributes and features: - The new edition is thoroughly compatible with the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders.- The chapters are complete unto themselves, allowing for easy retrieval and use by clinicians facing daily challenges in the field. Extensive references allow for further research and study in quieter moments.- Chapters on specific disorders have consistent structures, where appropriate. For example, the chapter on "Autism Spectrum Disorders" has sections on background, prevalence, etiology, neurobiology, clinical presentation, assessment, differential diagnosis, comorbidity, research, interventions and treatment, and medication.- The prestigious roster of contributors boasts both luminaries and emerging leaders in behavioral neurology and neuropsychiatry, providing readers with diverse perspectives.- The material is supported by scores of tables, graphs, and illustrations, including PET, CT, and MRI images. Neuropsychiatry has come a long way from the days when patients with neuropsychiatric conditions routinely fell through the cracks of the healthcare system.
