Until very recently, our knowledge about the neural basis of cognitive aging was based on two disciplines that had very little contact with each other. Whereas the neuroscience of aging investigated the effects of aging on the brain independently of age-related changes in cognition, the cognitive psychology of aging investigated the effects of aging on cognition independently of age-related changes in the brain. The lack of communication between these two disciplines is currently being addressed by an increasing number of studies that focus on the relationships between cognitive aging and cerebral aging. This rapidly growing body of research has come to constitute a new discipline, which may be called cognitive neuroscience of aging. The goal of this book is to introduce this new discipline. This book is divided into four main sections. The first section describes non-invasive measures of cerebral aging, including structural (e.g., volumetric MRI), chemical (e.g., dopamine PET), electrophysiological (e.g., ERPs), and hemodynamic (e.g., fMRI), and discusses how they can be linked to behavioral measures of cognitive aging. The second section reviews evidence for the effects of aging on neural activity during different cognitive functions, including perception and attention, imagery, working memory, long-term memory, and prospective memory. The third section focuses on clinical and applied topics, such as the distinction between healthy aging and Alzheimer's disease and the use of cognitive training to ameliorate age-related cognitive decline. The last section describes theories that relate cognitive and cerebral aging, including models accounting for functional neuroimaging evidence and models supported by computer simulations.

Gerontology for the Health Care Professional, Third Edition is a comprehensive, practical text covering the evolving field of gerontology, written for health care students and professionals. Written by experts across many health professions, Gerontology for the Health Care Professional, Third Edition presents an up-to-date and realistic view on the aging process. With topics presented in an introductory fashion, this book covers all the important aspects of aging and instills an appreciation for the multidimensional aspects of aging for those who are working with and caring for elderly patients or clients. Each chapter includes objectives, chapter outlines, cast studies, multiple-choice review questions, and learning activities. The Third Edition begins with chapters on different aspects of the aging process. Later chapters explore various issues that are of primary importance to the older population. This comprehensive, accessible text concludes with the future concerns of an aging society. There is also an epilogue encouraging all health care professionals to embrace patient or client advocacy, especially for older adults.
