Genes, Environment and Alzheimer's Disease discusses the role that activities such as exercise can play in cardiovascular health, while also highlighting the fact that the last 10 years have brought great discoveries in the strong environmental component of brain disorders, neurodegeneration, and cognitive decline. It is now clear that brain insult is an environmental risk factor for AD, while on the other hand, lifestyle components such as exercise and level of education may play a protective role, delaying the onset and/or severity of the disease. Evidence from experiments in rodent models of Alzheimer’s disease contributes major insight into the molecular mechanisms by which the environment plays its role in AD. Additionally, there are diseases related to lifestyle that may lead to AD. This volume reviews new discoveries related to all these factors, serving as a translational tool for clinicians and researchers interested in genetic and environmental risk factors for the disease. Provides the first volume to link genetic and environmental risk factors for Alzheimer’s disease and dementia Aids researchers and clinicians in understanding the basic mechanisms of Alzheimer’s disease and cognitive decline Brings the basic science and clinical perspectives together in a single volume, facilitating translational possibilities Includes a range of molecular to behavioral components assembled into a single volume that creates an excellent resource for basic and clinical neuroscientists

Along with psychopathology, cognition has been one of the primary phenotypic focal points of the field of behavior genetics since its inception. Francis Galton’s 1874 examination of eminent families in Britain was among the earliest attempts to investigate whether cognitive achievements run in families. This volume presents current methodologies for understanding cognitive abilities that move beyond the outdated nature vs. nurture paradigm. Recent advances in both collection and statistical modeling of twin data, particularly longitudinal twin data, make this an especially advantageous moment to produce a work that presents a collection of the groundbreaking research on cognitive abilities across the lifespan. This volume presents an overview of the current state of quantitative and molecular genetic investigations into the many facets of cognitive performance and functioning across the lifespan.​

Why do people age differently? Research in the field of gerontology has indicated that there are large individual differences in personality, cognitive functioning, physical health, and psychological well-being, as well as in the quality of life in the later years. It is this variability and the reasons why people age differently that this book explores. Thoughtfully written, Aging presents an overview of what is known about genetic and environmental influences on aging. Beginning with an overview of family, adoption, and twin designs, author Cindy S. Bergeman examines such topics as the research in the area of longevity and health, cognitive functioning, personality, and psychopathology; and social support, life events, and measures of the family environment. The book concludes with a summary of the field of gerontological behavioral genetics. This book will stimulate discussion and future work about the origins of individual differences in later life and will be invaluable to professionals and practitioners in the fields of developmental psychology, psychology, aging, family studies, and nursing.

Understanding the impact of diet, exercise, genetics, and hormones on the risk and development of Alzheimer’s and other neurogenerative diseases Diet is widely known to impact on neurological function. Nevertheless, academic texts discussing this relationship are relatively few in number. This book therefore fills an important gap in the current literature. Opening with an overview of neurodegenerative diseases, particularly Alzheimer’s disease, the text then focuses on explaining the means by which glycemic control and lipid metabolism – and associated nutritional and lifestyle variables – may factor into such disorders’ prevention and treatment. An international group of experts in the fields of food science and neurodegeneration have contributed chapters that examine Alzheimer’s disease within a broad range of contexts. Offering dietary, genetic, and hormonal perspectives, the authors explore topics ranging from sugar consumption to digestive fermentation, and Alzheimer’s disease animal models to the cognition-enhancing effects of physical exercise. Also included are overviews of the latest research into current and developing methods of treatment and diagnosis, as well as differential diagnostics. This groundbreaking book: Explores how glucose metabolism, insulin resistance, lipid metabolism, and high intake of refined carbohydrates are linked to Alzheimer's disease Discusses how genetic makeup can impact risk of Alzheimer’s and Parkinson’s disease Examines cognitive changes in neurodegeneration, lists current tests for determining cognitive impairment, and provides information concerning differential diagnosis Discusses potential advantages of increasing antioxidant and micronutrient intake Reviews hormonal influences on neurodegeneration Examines the links between protein intake and Alzheimer’s disease. Neurodegeneration and Alzheimer's Disease is an essential resource for researchers, medical practitioners, dietitians, and students with an interest in neurological diseases and their diagnosis and risk factors, as well as diet-related conditions such as diabetes and obesity. Lifestyle and diet influence neurodegeneration risk, and a better understanding of this evidence amongst health professionals will hopefully lead to greater public awareness of how to reduce the likelihood of these widespread conditions.

The etiology of Alzheimer's disease is multifaceted, involving a complex interplay of environmental and genetic factors. APOE [epislon]4 has been identified as the strongest genetic risk factor for Alzheimer's. Recent genome-wide association studies have also identified many non-APOE genetic variants that significantly contribute to Alzheimer's risk. Since these non-APOE variants typically have small effects, researchers often prefer to use a polygenic risk score to create a more robust predictor by combining the effects of these variants. However, the roles of APOE and non-APOE polygenic risk score in the disease's etiology, particularly during the preclinical stage of Alzheimer's, and whether different environmental exposures throughout life can modify the predisposed risk from APOE and non-APOE polygenic risk score, remain largely unknown. In this study, leveraging two longitudinal studies, we comprehensively evaluate how APOE, non-APOE polygenic risk score, and various environmental factors throughout life individually and jointly affect an individual's risk of Alzheimer's. We found that the effect of non-APOE polygenic risk score is particularly strong among APOE [epislon]4 carriers. Additionally, we observed that maintaining healthier lifestyles in mid-to-late life, or having an advantaged childhood socioeconomic status, can mitigate the adverse genetic effects of non-APOE polygenic risk score on later-life cognitive decline, especially among APOE [epislon]4 carriers. The findings from this research can serve as a foundation for future clinical trials and provide evidence for policymakers in designing effective policy interventions to address health disparities in Alzheimer's.

There is now considerable genetic evidence that the type 4 allele of the apolipoprotein E gene is a major susceptibility factor associated with late-onset Alzheimer's disease, the common form of the disease defined as starting after sixty years of age. The role of apolipoprotein E in normal brain metabolism and in the pathogenesis of Alzheimer's disease are new and exciting avenues of research. This book, written by the most outstanding scientists in this new filed, is the first presentation of results concerning the implications of apolipoprotein E on the genetics, cell biology, neuropathology, biochemistry, and therapeutic management of Alzheimer's disease.

Working from the intriguing hypothesis that Alzheimer's dementia is the result of a renegade protein-beta amyloid-Tanzi and others set out to find the gene responsible for its production. Decoding Darkness takes us deep into the minds and far-flung labs of many a prominent researcher, offering an intimate view of the high stakes of molecular genetics, the revolution that propels it, the obstacles that threaten to derail it, and the families whose lives are so dependent upon it. Tanzi and Parson ultimately reveal that Alzheimer's, like heart disease, may be effectively treated-even prevented.

Alzheimer’s Disease is the most common form of dementia. The disease is characterised by the loss of synapses and neurons in the cerebral cortex and certain subcortical regions. In the last three years, the genetics of Alzheimer’s Disease has made significant advances; in fact, one could argue more than in the previous two decades. This has resulted in the identification of nine new genes and perhaps more importantly the realization that new pathways could be involved in the pathogenesis of Alzheimer’s. These new pathways are now legitimate targets for therapeutic intervention, which can possibly lead to treatment or a possible cure. The aim of this book is to put all of the recent genetic data on these new genes into context. Different genetic variants will be discussed, as well as biomarkers and future possibilities. ​
