Widely recognized as the standard in its field, The American Psychiatric Publishing Textbook of Geriatric Psychiatry has been revised and updated while continuing the tradition of providing both scholar and clinician with the practical skills and knowledge required for understanding mental disorders in later life. It offers an authoritative review of a wide range of topics written by leaders in geriatric psychiatry, gerontology, geriatric medicine, and geriatric nursing, offering a solid grounding in both basic science and clinical applications. The book boasts comprehensive updates of the most common mental health disorders in the elderly -- from mood disorders and anxiety to schizophrenia and circadian rhythm disorders -- and includes in this fourth edition new chapters on delirium, dementia and milder cognitive syndromes, and bipolar disorders. Throughout the text, special attention has been given to updating key topics such as psychopharmacology, genetics, cognitive disorders, delirium, and agitation. The fourth edition: Presents the latest findings in neuropsychological assessment and its role in the diagnosis of Alzheimer's disease and in differentiating between various cognitive disorders. Summarizes key advances in genomic science and the current state of understanding about the genetics of the mental disorders of aging. Offers current recommendations for laboratory assessment of mental disorders, reflecting progress in research and technology over the past decade -- particularly in imaging technology and genetic testing -- while stressing the need to base tests on clinical presentations and on consideration of how results may change a treatment plan. Reviews assessment tools, diagnosis, prevention, and management approaches for delirium, emphasizing nonpharmacological approaches as the first line of treatment. Discusses specific dementia syndromes -- Alzheimer's dementia, vascular dementia, dementias due to Lewy body disease, and dementia due to frontotemporal degeneration -- along with approaches to treatment ranging from disease therapies to therapies for cognitive and neuropsychiatric symptoms. Provides new coverage of bipolar disorders, helping practitioners better understand basic facts about their onset in late life and including treatment guidelines based on case reports. The text is enhanced by a wide array of quick-reference tables and charts, lists of key points, and extensive references and suggested readings that can help students at all levels learn more about individual topics. The American Psychiatric Publishing Textbook of Geriatric Psychiatry is an unparalleled source for all medical professionals dealing with elderly patients, and is even more indispensable in this new edition.
