Aluminium and Alzheimer's Disease


Book Description

The subject of aluminium and Alzheimer's disease has been plagued with controversy. This controversy has served to obscure much of the scientific research in this field, and subsequently has obscured the possibility that aluminium is a contributory factor in the aetiology of Alzheimer's disease. This book brings together many of the world's leading scientists researching aluminium and life and contains their critical summaries on the known facts about aluminium toxicity in man and to offer an opinion on the implications of this knowledge on a link between aluminium and Alzheimer's disease. The subject areas of the chapters were chosen to reflect the myriad of ways that aluminium is known to impact upon mammalian physiology and function and range from clinical studies, through animal models of disease to the detailed biochemistry of aluminium toxicity. Chapters are also included on epidemiology and other factors involved in the aetiology of Alzheimer's.This is the first time that this subject has been treated in such a comprehensive manner. The research detailed in each chapter, includes the latest research in the field, it has been critically appraised and this appraisal has been used by each author to present an informed opinion of its relevance to aluminium and Alzheimer's disease. The chapters are much more than reviews; they are a statement of the state of the art and of what the future may hold for research in this field. As a whole they show the high quality of research that has been carried out in our efforts to understand the toxicity of aluminium in man and that we are far away from discounting the possibility that aluminium is a contributory factor in the aetiology of Alzheimer's disease.




Neurotoxicity of Aluminum


Book Description

This book reviews the scientific literature and the authors’ own research linking aluminum neurotoxicity with cognitive impairment and Alzheimer’s disease (AD). It focuses on aluminum levels in the brain, region-specific and subcellular distribution, and its relation to neurofibrillary tangles and amyloid beta. Further, the book stresses the importance of aluminum’s complex speciation chemistry in relation to biology, and details aluminum’s mechanism in oxidative stress and cell death, especially in connection with apoptosis and necroptosis. The electrophysiological variation and synaptic plasticity induced by aluminum are covered, while the metal’s debatable role in AD and the cross-talk between aluminum and genetic susceptibility are also discussed. In closing, the book reviews the neurotoxic effects of aluminum and its important role in the pathogenesis of AD. Given its depth of coverage, the book provides readers with a systematic summary of aluminum neurotoxicity.




Neurotoxicity of Metals


Book Description

Assembles international authorities to address contemporary research in metal neurotoxicity. Essential and non-essential metals play an important role in neurodevelopmental and neurodegenerative diseases. Recent developments in understanding the role of metals in the etiology of these disorders have led to rapid growth in clarifying the pathology of some of the most devastating diseases we face and in identifying potential new therapies. Few books or periodicals have been wholly dedicated to the topic of metals, and this collection is intended to serve as a resource for all researchers interested in metals and their role in health and disease.




Alzheimer's Disease: Cellular and Molecular Aspects of Amyloid beta


Book Description

To understand Alzheimer's disease (AD) is one of the major thrusts of present-day clinical research, strongly supported by more fimdamental cellular, biochemical, immunological and structural studies. It is these latter that receive attention within this book. This compilation of 20 chapters indicates the diversity of work currently in progress and summarizes the current state of knowledge. Experienced authors who are scientifically active in their fields of study have been selected as contributors to this book, in an attempt to present a reasonably complete survey of the field. Inevitably, some exciting topics for one reason or another have not been included, for which we can only apologize. Standardization of terminology is often a problem in science, not least in the Alzheimer field; editorial effort has been made to achieve standardization between the Chapters, but some minor yet acceptable personal / author variation is still present, i. e. P-amyloid/amyloid-P; Ap42/Apl-42/APi. 42! The book commences with a broad survey of the contribution that the range of available microscopical techniques has made to the study of Alzheimer's amyloid plaques and amyloid fibrillogenesis. This chapter also serves as an Introduction to the book, since several of the topics introduced here are expanded upon in later chapters. Also, it is significant to the presence of this chapter that the initial discovery of brain plaques, by Alois Alzheimer, utilized light microscopy, a technique that continues to be extremely valuable in present-day AD research.




Biochemical Mechanisms of Aluminium Induced Neurological Disorders


Book Description

Aluminium is a chemical element present in earth’s crust and it is a known environmental toxin which has been found to be associated with various neurological disorders. Aluminium has been found to be a very strong risk factor for the development of Alzheimer’s disease. Biochemical Mechanisms of Aluminium Induced Neurological Disorders explains the association of aluminium with neurological disorders. The book introduces the reader to sources of aluminium exposure, followed by an explanation of pharmacokinetics of aluminium and the different biochemical pathways that cause neurological effects. Chapters cover the typical mechanisms associated with aluminium neurotoxicity such as synaptic impairment as well as recent topics of interest such as the role of aluminum in impairing blood-brain barrier functions. Separate chapters which cover clinical evidence of aluminium toxicity and its management are also included in the book. Biochemical Mechanisms of Aluminium Induced Neurological Disorders is a concise, yet informative reference on the subject of aluminium neurotoxicity for all readers, whether they are students of biochemistry, pharmacology and toxicology, clinical neurologists, environmentalists interested in metal pollution or general readers who want to learn about the toxic effects of aluminium in humans.




Imagine You Are An Aluminum Atom


Book Description

Join "Mr. Aluminum," a scientist who has made the study of aluminum his life's work, on a journey of discovery, reflection, and the science of aluminum. Professor Christopher Exley is a firm believer that science is only useful when it is properly communicated. Scientific papers are difficult vehicles for the wider communication of science and thus he has always endeavored to tell the story of his scientific research as widely as possible through myriad blogs, presentations, and interviews. Through a series of easy-reading entries written for non-scientists, Exley will educate readers about his lifelong scientific passion: aluminum. In scientific circles, aluminum—in relation to human health specifically—has gone the way of the dinosaurs (though, unlike dinosaurs, there has not yet been a popular revival!). Yet aluminum is also the greatest untold story of science. But why do we all need to know a little bit more about aluminum? Do we need a self-help guide for living in what Exley has coined "The Aluminum Age"? What is it about aluminum that makes it different? What about iron, copper, or any of the so-called "heavy metals," like mercury, cadmium, or lead? Why must we pay particular attention to aluminum? Because its bio-geochemistry, its natural history, raises two red flags immediately and simultaneously. These two danger signals are easily missed by all of us and easily dismissed by those whose interests are conflicted by aluminum’s omnipresence in human life and consequently, are purposely blind to its danger signals. First, aluminum, in all of its myriad forms, is super abundant; it is the third most abundant element (after oxygen and silicon) of the Earth’s crust. Second, aluminum is super reactive; it is both chemically and biologically reactive. However, these two red flags identify a paradox, as the abundant and biologically reactive aluminum has no biological function either in any organism today nor in any extinct biota from the evolutionary past. This means in practical terms that when we encounter aluminum in our everyday lives, our bodies only see aluminum as an impostor, something foreign, and something for which we have not been prepared through biochemical evolution. This in turn means that all of our encounters with aluminium are adventitious, random, and chaotic. And potentially dangerous. Imagine You Are An Aluminum Atom: Discussions With "Mr. Aluminum" examines the science of aluminum and human health and makes them understandable to all. Within the science you will find personal recollections of events, as well as opinions and reflections upon how the politics of aluminum have influenced and interfered with doing and reporting the science. It is at once both a personal recollection of Exley's life in aluminum research and a guide on the dangers of the constant exposure to aluminum we as humans face during this "Aluminum Age." It will inform, it will provide the means to question the science, and it will, if the reader is prepared to participate, answer those frequently asked questions on aluminum and human health.

Magnesium in the Central Nervous System


Book Description

The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.




Neurodegeneration and Alzheimer's Disease


Book Description

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.
