Understanding Brain Aging And Dementia

The life course method compares an individual's long-life and late-life behaviors to gauge one's mental decay. Arguing the life course approach is the best and simplest model for tracking mental development, Lawrence J. Whalley unlocks the mysteries of brain functionality, illuminating the processes that affect the brain during aging, the causes behind these changes, and effective coping strategies. Whalley identifies the genetic factors that determine the pace of aging and the behaviors, starting in childhood, that influence how we age. Through vignettes, charts, and tables, he composes an accessible book for patients, family members, and caretakers struggling to make sense of a complex experience.

While growing older is inevitable, many of the troubles we associate with aging--including dementia, disability, and an increased dependence on others--are not. The choices we make now can help us to maintain our vitality, a sharp mind, and our independence as we age. Filled with simple, everyday actions we can take to avoid disease, promote vitality, and prevent dementia and late onset Alzheimer's, The Aging Brain is an easy-to-use guide to maintaining brain and body health throughout our lives. Based on solid, up-to-date scientific research, the interventions explained in this book not only prevent progression toward dementia even in those who have already shown mild cognitive impairment, they also reduce disability and depression and keep people living independently longer than those who do not practice these methods. For anyone hoping to slow the aging process, as well as anyone who acts as a caregiver to someone at risk of or already beginning to suffer from dementia and other age-related diseases, this book offers a hopeful, healthy way forward.

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.

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.

When confronted with a neurological or psychiatric disorder in an elderly individual, a clinician or researcher is likely to ask how the processes of ageing have influenced the aetiology and presentation of the disorder, and will impact on its efficient management. There are many urban myths about ageing, and some of these apply to the brain. The reviews included in this book are an attempt to flush out some of these myths, and arm the clinician and general researcher with the empirical facts that can be mustered to substantiate claims about ageing. There are many salient questions: is cognitive change to be expected in an elderly individual? Is this change progressive, relentless and unselective, or is it focal and constrained? Would every person who lived long enough develop Alzheimer’s disease? Do our neurones die as we get old? What happens to the size of the brain and its metabolic activity? How do our hormones change with age? Can anti-oxidants slow or even stop the process of ageing? Are genes important in the ageing brain or is it all in the environment? How much of what we are is due to what we eat? The contributors to this book, each an expert in their field, have addressed some of these questions in a language simple enough for a general reader to understand. The book also deals with some of the most prominent brain disorders of old age - Alzheimer's disease, Parkinson's disease, vascular dementia, and depression. The focus is on the impact of ageing on these disorders. The discussions lay out a broad map for the clinician dealing with neuropsychiatric disorders, and the future researcher of brain ageing. In a field in which the developments are too numerous for any one individual to keep pace with, this book presents up-to-date summaries that can be a useful starting point. The field of brain ageing abounds in tabloid science. This book counters this by providing a strong empirical grounding and considered synthesis of the research.

A thought-provoking treatise on understanding and treating the aging mind and brain This handbook recognizes the critical issues surrounding mind and brain health by tackling overarching and pragmatic needs so as to better understand these multifaceted issues. This includes summarizing and synthesizing critical evidence, approaches, and strategies from multidisciplinary research—all of which have advanced our understanding of the neural substrates of attention, perception, memory, language, decision-making, motor behavior, social cognition, emotion, and other mental functions. Written by a plethora of health experts from around the world, The Wiley Handbook on the Aging Mind and Brain offers in-depth contributions in 7 sections: Introduction; Methods of Assessment; Brain Functions and Behavior across the Lifespan; Cognition, Behavior and Disease; Optimizing Brain Function in Health and Disease; Forensics, Competence, Legal, Ethics and Policy Issues; and Conclusion and New Directions.
