Diet And Cognitive Decline

Diet and Nutrition in Dementia and Cognitive Decline offers researchers and clinicians a single authoritative source which outlines the complex interrelationships between cognitive decline, dementia and the way diet can be modified to improve outcomes. In a cross-disciplinary field like dementia research and practice, clinicians and researchers need a comprehensive resource which will quickly help them identify a range of nutritional components and how they affect cognitive decline and the development of dementia. While the focus is on clinical applications, the book also features landmark and innovative preclinical studies that have served as the foundation of rigorous trials. Chapters explore the evidence of how nutritional components, either in the diet or supplements, can either impede the development to, or progression from, the onset of dementia. Authors investigate how conditions and processes overlap between defined conditions and present studies which show that dietary components may be equally effective in a number of conditions characterized by declining cognition or dementia. This book represents essential reading for researchers and practicing clinicians in nutrition, dietetics, geriatrics, nursing, neurology, and psychology, as well as researchers, such as neuroscientists, molecular and cellular biochemists, interested in dementia. Explores the complex interrelationships between cognitive decline, dementia and the way diet can be modified to improve outcomes Focuses on both clinical nutrition applications and the innovative preclinical studies that serve as the foundation for rigorous trials Covers specific conditions and mechanisms in dementias, as well as general aspects, risk factors, lifestyle and guidelines for practitioners Organizes chapter content in terms of the molecular, mechanistic, epidemiologic, and practical, so that correlations can be observed across conditions

The progressive ageing of the general population and the consequent increase of the number of old people has made the typical medical problems of aged people more frequently observed, and particularly the problems related to the ageing brain. This new book is an updated overview of relevant aspects of cognitive decline associated with ageing. Within the wide landscape of brain ageing the authors reconsider the role of the main predisposing factors and risk factors on the development of various form of mental decline, from mild cognitive impairment to dementia. The strength of this book is the large, updated overview of the most recent data of scientific literature regarding the role of genetic, metabolic and environmental factors on the predisposition and onset of cognitive decline. Particular attention is paid to the dietary micro- and macronutrients and to their possible role in the pathogenesis of the various form of dementigen disorders.

Role of the Mediterranean Diet in the Brain and Neurodegenerative Disease provides a comprehensive overview of the effects of all components of the Mediterranean diet on the brain, along with its beneficial effects in neurodegenerative diseases. It covers topics on neurodegenerative diseases (Alzheimer disease (AD), Parkinson disease, (PD) Huntington disease (HD) and Amyotrophic Lateral Sclerosis (ALS), also providing information on how cardiovascular disease, Type 2 Diabetes, and Metabolic Syndrome become risk factors for neurodegenerative diseases. This book focuses on how the Mediterranean diet suppresses oxidative stress and neuroinflammation in neurodegenerative diseases as well as signal transduction. The Mediterranean diet is characterized by the abundant consumption of olive oil, high consumption of plant foods (fruits, vegetables, pulses, cereals, nuts and seeds); frequent and moderate intake of wine (mainly with meals); moderate consumption of fish, seafood, yogurt, cheese, poultry and eggs; and low consumption of red meat and processed meat products. High consumption of dietary fiber, low glycemic index and glycemic load, anti-inflammatory effects, and antioxidant compounds may act together to produce favorable effects on health status. Collective evidence suggests that Mediterranean diet not only increases longevity by lowering cardiovascular disease, inhibiting cancer growth, but also by protecting the body from age-dependent cognitive decline. Comprehensively provides an overview of the effects of the Mediterranean diet on the brain and its beneficial effects in neurodegenerative diseases Discusses the relationship among Type 2 Diabetes, Metabolic Syndrome and Alzheimer's Disease, and the effect of the Mediterranean diet on normal aging, longevity, and other neurodegenerative diseases Focuses on how the Mediterranean diet suppresses oxidative stress and neuroinflammation in neurodegenerative disease

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.

Changes in food composition and availability have contributed to the dramatic increase in obesity over the past 30-40 years in developed and, increasingly, in developing countries. The modern diet now contains many foods that are rich in saturated fat and refined sugar. People who eat excessive amounts of this diet are not only likely to become overweight, even obese, develop metabolic and cardiovascular diseases, some forms of cancer, but also undergo a more rapid rate of normal age-related cognitive decline and more rapid progression of neurological diseases such as dementia. A central problem is why people persist in consuming this diet in spite of its adverse health effects and when alternative food choices are available. As high fat / high sugar foods are inherently rewarding, eating for pleasure, like taking psychoactive drugs, can modulate reward neurocircuitry, causing changes in responsiveness to reward-predicting stimuli and incentive motivation. Indeed, the excessive ingestion in modern societies and the resulting obesity epidemic may be viewed as a form of food addiction. Thus, a diet high in palatable foods is proposed to impact upon reward systems in the brain, modulating appetitive learning and altering reward thresholds. Impairments in other forms of cognition have been associated with obesity, and these have a rapid onset. The hippocampus appears to be particularly vulnerable to the detrimental effects of high fat and high sugar diets. Recent research has shown that as little as one week of exposure to a high fat, high sugar diet leads to impairments in place but not object recognition memory in the rat. Excess sugar alone had similar effects, and the detrimental effects of diet consumption was linked to increased inflammatory markers in the hippocampus, a critical region involved in memory. Furthermore, obesity-related inflammatory changes have also been described in the human brain that may lead to memory impairments. These memory deficits may contribute to pathological eating behaviour through changes in the amount consumed and timing of eating. The aim of this eBook is to present up-to-date information about the impact of diet and diet-induced obesity on reward driven learning, memory and cognition, encompassing both animal and human literature, and also potential therapeutic targets to attenuate such deficits.

Drawing on the 2019 revision of World Population Prospects, the World Population Ageing 2019 (Highlights) document global and regional trends in population ageing, including consideration of the implications of these trends for the implementation of the 2030 Agenda. The report also presents various concepts and indicators related to population ageing and discusses related fiscal and economic implications.

Diet and exercise have long been recognized as important components of a healthy lifestyle, as they have a great impact on improving cardiovascular and cerebrovascular functions, lowering the risk of metabolic disorders, and contributing to healthy aging. As a greater proportion of the world’s population is living longer, there has been increased interest in understanding the role of nutrition and exercise in long-term neurological health and cognitive function. Diet and Exercise in Cognitive Function and Neurological Diseases discusses the role and impact that nutrition and activity have on cognitive function and neurological health. The book is divided into two sections. The first section focuses on diet and its impact on neurobiological processes. Chapters focus on the impacts of specific diets, such as the Mediterranean, ketogenic and vegan diets, as well as the role of specific nutrients, fats, fatty acids, and calorie restriction on neurological health and cognitive function. The second section of the book focuses on exercise, and its role in maintaining cognitive function, reducing neuroinflammatory responses, regulating adult neurogenesis, and healthy brain aging. Other chapters look at the impact of exercise in the management of specific neurological disorders such Multiple Sclerosis and Parkinson’s Disease. Diet and Exercise in Cognitive Function and Neurological Diseases is a timely reference on the neurobiological interplay between diet and exercise on long-term brain health and cognitive function.
