New Frontiers In Cognitive Aging

With an ever increasing population of aging people in the western world, it is more crucial than ever that we try to understand how and why cognitive competence breaks down with advancing age; why do some people follow normal patterns of cognitive change, while others follow a path of progressive decline, with neurodegenerative diseases such as Alzheimer's. What can be done to prevent cognitive decline - or to avoid neurodegenerative diseases? The answers, if they come, will not emerge from research within one discipline, but from work being done across a range of scientific and medical specialities. This volume brings together leading experts from a range of fields studying cognitive aging, including neuroscience, pharmacology, health, genetics, sensory biology, and epidemiology. Unlike other books in this area, this book is more about 'new frontiers' than past research and accomplishments. Recently cognitive aging research has taken several new directions, linking with, and benefiting from, rapid technological and theoretical advances in these neighbouring disciplines. This book provides unique interdisciplinary coverage of the topic. With each chapter including commentaries from specialists in related fields, the book provides an integrative study of the topic. For those within the fields of psychology, cognitive neuroscience, and geriatrics, this volume will make an important contribution in furthering our understanding of a problem that affects us all.

A typically pessimistic view of aging is that it leads to a steady decline in physical and mental abilities. In this volume leading gerontologists and geriatric researchers explore the immense potential of older adults to overcome the challenges of old age and pursue active lives with renewed vitality. The contributors believe that resilience capacities diminishing with old age is a misconception and argue that individuals may successfully capitalize on their existing resources, skills and cognitive processes in order to achieve new learning, continuing growth, and enhanced life-satisfaction. By identifying useful psychological resources such as social connectedness, personal engagement and commitment, openness to new experiences, social support and sustained cognitive activity, the authors present a balanced picture of resilient aging. Older adults, while coping with adversity and losses, can be helped to maintain a complementary focus on psychological strengths, positive emotions, and regenerative capacities to achieve continued growth and healthy longevity.

Recognition that aging is not the accumulation of disease, but rather comprises fundamental biological processes that are amenable to experimental study, is the basis for the recent growth of experimental biogerontology. As increasingly sophisticated studies provide greater understanding of what occurs in the aging brain and how these changes occur

Cognitive aging is a flourishing area of research. A significant amount of new data, a number of new theoretical notions, and many new research issues have been generated in the past ten years. This new edition reviews new findings and theories, enables the reader to assess where the field is today, and evaluates its points of growth. The chapters are organized to run from reviews of current work on neuroimaging, neuropsychology, genetics and the concept of brain reserve, through the 'mainstream' topics of attention, memory, knowledge and language, to a consideration of individual differences and of cognitive aging in a lifespan context. This edition continues to feature the broad range of its predecessors, while also providing critical assessments of current theories and findings.

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 Cognitive Neuroscience of Aging is to introduce the reader to this new discipline at a level that is useful to both professionals and students in the domains of cognitive neuroscience, cognitive psychology, neuroscience, neuropsychology, neurology, and other, related areas. This book is divided into four main sections. The first section describes noninvasive 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 Alzheimers 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. Taken together, the chapters in this volume provide the first unified and comprehensive overview of the new discipline of cognitive neuroscience of aging.

Possible new breakthroughs in understanding the aging mind that can be used to benefit older people are now emerging from research. This volume identifies the key scientific advances and the opportunities they bring. For example, science has learned that among older adults who do not suffer from Alzheimer's disease or other dementias, cognitive decline may depend less on loss of brain cells than on changes in the health of neurons and neural networks. Research on the processes that maintain neural health shows promise of revealing new ways to promote cognitive functioning in older people. Research is also showing how cognitive functioning depends on the conjunction of biology and culture. The ways older people adapt to changes in their nervous systems, and perhaps the changes themselves, are shaped by past life experiences, present living situations, changing motives, cultural expectations, and emerging technology, as well as by their physical health status and sensory-motor capabilities. Improved understanding of how physical and contextual factors interact can help explain why some cognitive functions are impaired in aging while others are spared and why cognitive capability is impaired in some older adults and spared in others. On the basis of these exciting findings, the report makes specific recommends that the U.S. government support three major new initiatives as the next steps for research.
