In this text, world-renowned neuropsychiatrists and neuroscientists provide practical application of the latest research for both experienced clinicians and those new to the study of neuropsychiatry for the elderly. The book provides a comprehensive approach to treatment and contemporary neuroscience: Addresses the reality of an increasing aging population and the accompanying psychosocial changes this brings for patients and caregivers. Focuses on the health care of patients with neuropsychiatric illness. Consolidating the continued explosion of neuroscience research and the understanding of human behavior as it relates to aging. Bridges the fields of geriatric neurology and geriatric psychiatry, emphasizing relationships between neuropsychiatric illness and the aging of the nervous system. Responds to advancements in the study and science of geriatric neuropsychiatry, as well as feedback from past readers and clinicians. Concise and organized for easy reference, the textbook is divided into four parts that disclose clinically relevant information within the context of the very latest in neuroscience research and clinical application, including: Clinical definitions of the essential neuropsychiatric syndromes and disorders commonly seen in the elderly and how these disorders manifest. Emphasis on the principles and special considerations essential for the safe and effective treatment of neuropsychiatric disorders in the elderly. Study of the importance of interactions among aging; psychosocial, family, and neuropharmacological elements; and brain stimulation therapies. In-depth review of the influence of the aging nervous system on the pathophysiology, neuropsychiatric manifestations, clinical course, and prognosis of neurological and psychiatric illness in the elderly. Geriatric neuropsychiatry is an integrative specialty that draws from a diversity of fields including psychiatry, neuropsychiatry, neuroimaging, neuropsychopharmacology, gerontology, genetics, and molecular biology, to name a few. Incorporating these perspectives, this text is highly recommended for psychiatrists, neurologists, psychologists, geriatricians, psychiatric nurses, residents and fellows, and other clinicians interested in the study and treatment of the effects of aging on the brain.
