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.

Alzheimer disease causes the gradual deterioration of cognitive function, including severe memory loss and impairments in abstraction and reasoning. Understanding the complex changes that occur in the brain as the disease progressesincluding the accumulation of amyloid plaques and neurofibrillary tanglesis critical for the development of successful therapeutic approaches. Written and edited by leading experts in the field, this collection from Cold Spring Harbor Perspectives in Medicine includes contributions covering all aspects of Alzheimer disease, from our current molecular understanding to therapeutic agents that could be used to treat and, ultimately, prevent it. Contributors discuss the biochemistry and cell biology of amyloid -protein precursor (APP), tau, presenilin, -secretase, and apolipoprotein E and their involvement in Alzheimer disease. They also review the clinical, neuropathological, imaging, and biomarker phenotypes of the disease; genetic alterations associated with the disorder; and epidemiological insights into its causation and pathogenesis. This comprehensive volume, which includes discussions of therapeutic strategies that are currently used or under development, is a vital reference for neurobiologists, cell biologists, pathologists, and other scientists pursuing the biological basis of Alzheimer disease, as well as investigators, clinicians, and students interested in its pathogenesis, treatment, and prevention.

This open access book provides insight on how to interpret capability in ageing – one’s individual ability to perform actions in order to reach goals one has reason to value – from a multidisciplinary approach. With for the first time in history there being more people in the world aged 60 years and over than there are children below the age of 5, the book describes this demographic trends as well as the large global challenges and important societal implications this will have such as a worldwide increase in the number of persons affected with dementia, and in the ratio of retired persons to those still in the labor market. Through contributions from many different research areas, it discussed how capability depends on interactions between the individual (e.g. health, genetics, personality, intellectual capacity), environment (e.g. family, friends, home, work place), and society (e.g. political decisions, ageism, historical period). The final chapter summarizes the differences and similarities in these contributions. As such this book provides an interesting read for students, teachers and researchers at different levels and from different fields interested in capability and multidisciplinary research.

Sex and Gender Differences in Alzheimer's Disease: The Women's Brain Project offers for the first time a critical overview of the evidence documenting sex and gender differences in Alzheimer's disease neurobiology, biomarkers, clinical presentation, treatment, clinical trials and their outcomes, and socioeconomic impact on both patients and caregivers. This knowledge is crucial for clinical development, digital health solutions, as well as social and psychological support to Alzheimer's disease families, in the frame of a precision medicine approach to Alzheimer's disease.This book brings together up-to-date findings from a variety of experts, covering basic neuroscience, epidemiology, diagnosis, treatment, clinical trials development, socioeconomic factors, and psychosocial support. Alzheimer's disease, the most common form of dementia, remains an unmet medical need for the planet. Wide interpersonal variability in disease onset, presentation, and biomarker profile make Alzheimer's a clinical challenge to neuroscientists, clinicians, and drug developers alike, resulting in huge management costs for health systems and society. Not only do women represent the majority of Alzheimer's disease patients, but they also represent two-thirds of caregivers. Understanding sex and gender differences in Alzheimer's disease will lead to novel insights into disease mechanisms, and will be crucial for personalized disease management strategies and solutions, involving both the patient and their family. Endorsements/Reviews: "There is a clear sex and gender gap in outcomes for brain health disorders like Alzheimer's disease, with strikingly negative outcomes for women. This understanding calls for a more systematic way of approaching this issue of inequality. This book effectively highlights and frames inequalities in all areas across the translational spectrum from bench-to-bedside and from boardroom-to-policy and economics. Closing the Brain Health Gap will help economies create recovery and prepare our systems for future global shocks." Harris A. Eyre MBBS, PhD, co-lead, Neuroscience-inspired Policy Initiative, OECD and PRODEO Institute. Instructor in Brain Health Diplomacy, Global Brain Health Institute, UCSF and TCD. "Sex and Gender Differences in Alzheimer's disease is the most important title to emerge on Alzheimer's disease in recent years.This comprehensive, multidisciplinary book is a must read for anyone with a serious interest in dementia prevention, diagnosis, treatment, care, cure and research. Precision medicine is the future of healthcare and this book represents an incredible and necessary resource to guide practice, policy and research in light of the fact that Alzheimer's disease disproportionately affects women. The combination of contributions from the most eminent experts and the most up-to-date research makes this an invaluable resource for clinicians, care providers, academics, researchers and policy makers. Given the complex nature of dementia and the multiple factors that influence risk and disease trajectory the scope of the book is both impressive and important covering sex differences in neurobiological processes, sex and gender differences in clinical aspects and gender differences linked to socioeconomic factors relevant to Alzheimer's disease. If you work in Alzheimer's disease, or indeed other dementias, then Sex and Gender Differences in Alzheimer's disease is a must have for your bookshelf." -- Sabina Brennan, PhD., C.Psychol.,PsSI., National representative for Ireland on Alzheimer Disease International's Medical and Scientific Advisory Panel

An authority on Alzheimer's disease offers a history of past failures and a roadmap that points us in a new direction in our journey to a cure. For decades, some of our best and brightest medical scientists have dedicated themselves to finding a cure for Alzheimer's disease. What happened? Where is the cure? The biggest breakthroughs occurred twenty-five years ago, with little progress since. In How Not to Study a Disease, neurobiologist Karl Herrup explains why the Alzheimer's discoveries of the 1990s didn't bear fruit and maps a direction for future research. Herrup describes the research, explains what's taking so long, and offers an approach for resetting future research. Herrup offers a unique insider's perspective, describing the red flags that science ignored in the rush to find a cure. He is unsparing in calling out the stubbornness, greed, and bad advice that has hamstrung the field, but his final message is a largely optimistic one. Herrup presents a new and sweeping vision of the field that includes a redefinition of the disease and a fresh conceptualization of aging and dementia that asks us to imagine the brain as a series of interconnected "neighborhoods." He calls for changes in virtually every aspect of the Alzheimer's disease research effort, from the drug development process, to the mechanisms of support for basic research, to the often-overlooked role of the scientific media, and more. With How Not to Study a Disease, Herrup provides a roadmap that points us in a new direction in our journey to a cure for Alzheimer's.

Alzheimer’s Disease is characterized pathologically by two principal hallmark lesions: the senile plaque and the neurofibrillary tangle. Since the identification of each over 100 years ago, the major protein components have been elucidated. This has led in turn to the elaboration of metabolic cascades involving amyloid-β production in the case of the senile plaque, and phosphorylated-tau protein in the case of the neurofibrillary tangle. The pathogenesis and histogenesis of each have been the source of extensive investigation and some controversy in recent years, as both cascades have been implicated in the pathogenesis of Alzheimer’s Disease, relied upon in the diagnostic criteria for Alzheimer’s Disease at autopsy, and targeted for therapeutic intervention. With the accumulation of data and expansion of knowledge of the molecular biology of Alzheimer’s Disease, it appears that the enthusiasm for successful intervention has been premature. In this book, we detail the discovery and characterization of the major pathological lesions, their associated molecular biology, their relationship to clinical disease, and potential fundamental errors in understanding that may be leading scientific investigators in unintended directions.

Here is a comprehensive overview of the drugs that act on the central and peripheral nervous systems. This volume thoroughly describes the diseases associated with the nervous system and the drugs used for their treatment while also looking at the current status of these drugs and their future potential and challenges. Divided into three sections, the book first focuses on the drugs that affect the functions of the autonomic nervous system to produce therapeutic effects. These drugs may act presynaptically by manipulating the genesis, storage, and secretion, and by blocking the action of neurotransmitters. Some drugs may trigger or impede postsynaptic receptors. Section 2 focuses on drugs that affect the central nervous system, including antianxiety drugs, sedative and hypnotic drugs, antidepressant drugs, antipsychotic drugs, antiepileptic drugs, and many more. It covers the pharmacological management of various diseases, including Alzheimer’s, Parkinson’s, Huntington’s, and others. The last section offers explanations of neurochemical interactions with the aim to develop drugs that have beneficial effects on neurochemical imbalances. This section demonstrates models to assess the transport of drugs across the blood-brain barrier and nanomedicine to treat brain disorders. This rich compilation provides thorough and extensive research updates on the important advances in neuropharmacological drugs and drug therapy from experienced and eminent academicians, researchers, and scientists from throughout the world.

Neuronal nicotinic receptors are key molecules for signal transduction in a number of neuronal pathways. They are widely distributed in the brain and are known to be involved in cognitive tasks, including learning and memory, in smoking addiction and in several brain diseases, such as Alzheimer's and Parkinson's dementias, schizophrenia, and epilepsy. This book provides a comprehensive review of the field, starting with a historical perspective and dealing with the molecular structure of these receptors, their biophysical and pharmacological properties, their distribution in central and peripheral nervous systems, and their major involvement in brain functions. Particular emphasis is paid to drugs (both new and old) that are useful in the diagnosis and treatment of diseases involving neuronal nicotinic receptors. Finally, the relevance of these receptors in smoking addiction is carefully evaluated, together with future trends and the latest results.

Neurofibrillary tangles (NFTs) composed of intracellular aggregates of tau protein are a key neuropathological feature of Alzheimer’s Disease (AD) and other neurodegenerative diseases, collectively termed tauopathies. The abundance of NFTs has been reported to correlate positively with the severity of cognitive impairment in AD. However, accumulating evidences derived from studies of experimental models have identified that NFTs themselves may not be neurotoxic. Now, many of tau researchers are seeking a “toxic” form of tau protein. Moreover, it was suggested that a “toxic” tau was capable to seed aggregation of native tau protein and to propagate in a prion-like manner. However, the exact neurotoxic tau species remain unclear. Because mature tangles seem to be non-toxic component, “tau oligomers” as the candidate of “toxic” tau have been investigated for more than one decade. In this topic, we will discuss our consensus of “tau oligomers” because the term of “tau oligomers” [e.g. dimer (disulfide bond-dependent or independent), multimer (more than dimer), granular (definition by EM or AFM) and maybe small filamentous aggregates] has been used by each researchers definition. From a biochemical point of view, tau protein has several unique characteristics such as natively unfolded conformation, thermo-stability, acid-stability, and capability of post-translational modifications. Although tau protein research has been continued for a long time, we are still missing the mechanisms of NFT formation. It is unclear how the conversion is occurred from natively unfolded protein to abnormally mis-folded protein. It remains unknown how tau protein can be formed filaments [e.g. paired helical filament (PHF), straight filament and twisted filament] in cells albeit in vitro studies confirmed tau self-assembly by several inducing factors. Researchers are still debating whether tau oligomerization is primary event rather than tau phosphorylation in the tau pathogenesis. Inhibition of either tau phosphorylation or aggregation has been investigated for the prevention of tauopathies, however, it will make an irrelevant result if we don’t know an exact target of neurotoxicity. It is a time to have a consensus of definition, terminology and methodology for the identification of “tau oligomers”.
