Decades of research have demonstrated that normal aging is accompanied by cognitive change. Much of this change has been conceptualized as a decline in function. However, age-related changes are not universal, and decrements in older adult performance may be moderated by experience, genetics, and environmental factors. Cognitive aging research to date has also largely emphasized biological changes in the brain, with less evaluation of the range of external contributors to behavioral manifestations of age-related decrements in performance. This handbook provides a comprehensive overview of cutting-edge cognitive aging research through the lens of a life course perspective that takes into account both behavioral and neural changes. Focusing on the fundamental principles that characterize a life course approach - genetics, early life experiences, motivation, emotion, social contexts, and lifestyle interventions - this handbook is an essential resource for researchers in cognition, aging, and gerontology.

Almost 25 years have passed since the Demography of Aging (1994) was published by the National Research Council. Future Directions for the Demography of Aging is, in many ways, the successor to that original volume. The Division of Behavioral and Social Research at the National Institute on Aging (NIA) asked the National Academies of Sciences, Engineering, and Medicine to produce an authoritative guide to new directions in demography of aging. The papers published in this report were originally presented and discussed at a public workshop held in Washington, D.C., August 17-18, 2017. The workshop discussion made evident that major new advances had been made in the last two decades, but also that new trends and research directions have emerged that call for innovative conceptual, design, and measurement approaches. The report reviews these recent trends and also discusses future directions for research on a range of topics that are central to current research in the demography of aging. Looking back over the past two decades of demography of aging research shows remarkable advances in our understanding of the health and well-being of the older population. Equally exciting is that this report sets the stage for the next two decades of innovative researchâ€"a period of rapid growth in the older American population.

For most Americans, staying "mentally sharp" as they age is a very high priority. Declines in memory and decision-making abilities may trigger fears of Alzheimer's disease or other neurodegenerative diseases. However, cognitive aging is a natural process that can have both positive and negative effects on cognitive function in older adults - effects that vary widely among individuals. At this point in time, when the older population is rapidly growing in the United States and across the globe, it is important to examine what is known about cognitive aging and to identify and promote actions that individuals, organizations, communities, and society can take to help older adults maintain and improve their cognitive health. Cognitive Aging assesses the public health dimensions of cognitive aging with an emphasis on definitions and terminology, epidemiology and surveillance, prevention and intervention, education of health professionals, and public awareness and education. This report makes specific recommendations for individuals to reduce the risks of cognitive decline with aging. Aging is inevitable, but there are actions that can be taken by individuals, families, communities, and society that may help to prevent or ameliorate the impact of aging on the brain, understand more about its impact, and help older adults live more fully and independent lives. Cognitive aging is not just an individual or a family or a health care system challenge. It is an issue that affects the fabric of society and requires actions by many and varied stakeholders. Cognitive Aging offers clear steps that individuals, families, communities, health care providers and systems, financial organizations, community groups, public health agencies, and others can take to promote cognitive health and to help older adults live fuller and more independent lives. Ultimately, this report calls for a societal commitment to cognitive aging as a public health issue that requires prompt action across many sectors.

Societies around the world are concerned about dementia and the other forms of cognitive impairment that affect many older adults. We now know that brain changes typically begin years before people show symptoms, which suggests a window of opportunity to prevent or delay the onset of these conditions. Emerging evidence that the prevalence of dementia is declining in high-income countries offers hope that public health interventions will be effective in preventing or delaying cognitive impairments. Until recently, the research and clinical communities have focused primarily on understanding and treating these conditions after they have developed. Thus, the evidence base on how to prevent or delay these conditions has been limited at best, despite the many claims of success made in popular media and advertising. Today, however, a growing body of prevention research is emerging. Preventing Cognitive Decline and Dementia: A Way Forward assesses the current state of knowledge on interventions to prevent cognitive decline and dementia, and informs future research in this area. This report provides recommendations of appropriate content for inclusion in public health messages from the National Institute on Aging.

The U.S. population is aging. Social Security projections suggest that between 2013 and 2050, the population aged 65 and over will almost double, from 45 million to 86 million. One key driver of population aging is ongoing increases in life expectancy. Average U.S. life expectancy was 67 years for males and 73 years for females five decades ago; the averages are now 76 and 81, respectively. It has long been the case that better-educated, higher-income people enjoy longer life expectancies than less-educated, lower-income people. The causes include early life conditions, behavioral factors (such as nutrition, exercise, and smoking behaviors), stress, and access to health care services, all of which can vary across education and income. Our major entitlement programs - Medicare, Medicaid, Social Security, and Supplemental Security Income - have come to deliver disproportionately larger lifetime benefits to higher-income people because, on average, they are increasingly collecting those benefits over more years than others. This report studies the impact the growing gap in life expectancy has on the present value of lifetime benefits that people with higher or lower earnings will receive from major entitlement programs. The analysis presented in The Growing Gap in Life Expectancy by Income goes beyond an examination of the existing literature by providing the first comprehensive estimates of how lifetime benefits are affected by the changing distribution of life expectancy. The report also explores, from a lifetime benefit perspective, how the growing gap in longevity affects traditional policy analyses of reforms to the nation's leading entitlement programs. This in-depth analysis of the economic impacts of the longevity gap will inform debate and assist decision makers, economists, and researchers.

This second edition of the popular Cognitive Neuroscience of Aging provides up-to-date coverage of the most fundamental topics in this discipline. Like the first edition, this volume accessibly and comprehensively reviews the neural mechanisms of cognitive aging appropriate to both professionals and students in a variety of domains, including psychology, neuroscience, neuropsychology, neurology, and psychiatry. The chapters are organized into three sections. The first section focuses on major questions regarding methodological approaches and experimental design. It includes chapters on structural imaging (MRI, DTI), functional imaging (fMRI), and molecular imaging (dopamine PET, etc), and covers multimodal imaging, longitudinal studies, and the interpretation of imaging findings. The second section concentrates on specific cognitive abilities, including attention and inhibitory control, executive functions, memory, and emotion. The third section turns to domains with health and clinical implications, such as the emergence of cognitive deficits in middle age, the role of genetics, the effects of modulatory variables (hypertension, exercise, cognitive engagement), and the distinction between healthy aging and the effects of dementia and depression. Taken together, the chapters in this volume, written by many of the most eminent scientists as well as young stars in this discipline, provide a unified and comprehensive overview 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.

The phenomenon of age-related cognitive decline has long been controversial, both in terms of mere existence, and with respect to how it is explained. Some researchers have dismissed it as an artifact of declining health or lower levels of education, and others have attributed it to general changes occurring in the external environment. Still other interpretations have been based on the "use it or lose it" principle -- known as the Disuse Hypothesis -- or on the idea that there are qualitative differences in either the structure or the process of cognition across the adult years. Perhaps the most popular approach at present relies on the information-processing perspective and attempts to identify the critical processing component most responsible for age-related differences in cognition. The primary purposes of this book are first to review the evidence of age-related differences in cognitive functioning and then to evaluate the major explanations proposed to account for the negative relations between age and cognition that have been established. Included is a discussion of theoretical dimensions and levels of scientific theorizing assumed to be helpful in understanding and evaluating alternative perspectives on cognitive aging. The various perspectives are then covered in detail and analyzed. The text concludes with observations about the progress that has been made in explaining cognitive aging phenomena, plus recommendations for research practices that might contribute to greater progress in the future.
