Environmental Cns Stimulation In Aging Health And Disease

Social and environmental factors have profound impacts on health and diseases across the lifespan. Each year, hundreds of millions of animals are used in biomedical research. Yet many experimental studies utilize animals housed in standard conditions conferring minimal physical, social, and mental stimulation. Lacking appreciation of macroenvironment impacts on physiology and disease risks of the laboratory animals may not only hinder the use of appropriate animal models for human diseases, but also question the validity of preclinical assessments of therapeutic agents.This book summarizes our work on environmental enrichment, a housing condition for laboratory animals, recapitulating an active lifestyle by providing a complex physical, social, and cognitive stimulations. Environmental enrichment exerts a wide range of benefits on energy balance, cancer, immunity, stress, behavior, and healthy aging. One underlying mechanism is the activation of a specific neuroendocrine brain-adipocyte axis with brain-derived neurotrophic factor as the key brain mediator. This book integrates recent discoveries regarding mechanisms, mediators, and biomarkers of environmental enrichment, and discusses its translational potential.By providing a timely review and discussion of murine models, this book should be of interest to basic, translational, and clinical researchers, as well as psychologists, nutrition scientists, and students that have interest in cancer, obesity, aging, and genetic disorders.

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.

Scientists agree that exposure to toxic agents in the environment can cause neurological and psychiatric illnesses ranging from headaches and depression to syndromes resembling parkinsonism. It can even result in death at high exposure levels. The emergence of subclinical neurotoxicity-the concept that long-term impairments can escape clinical detection-makes the need for risk assessment even more critical. This volume paves the way toward definitive solutions, presenting the current consensus on risk assessment and environmental toxicants and offering specific recommendations. The book covers: The biologic basis of neurotoxicity. Progress in the application of biologic markers. Reviews of a wide range of in vitro and in vivo testing techniques. The use of surveillance and epidemiology to identify neurotoxic hazards that escape premarket screening. Research needs. This volume will be an important resource for policymakers, health specialists, researchers, and students.

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.

Recognition that aging is not the accumulation of disease, but rather comprises fundamental biological processes that are amenable to experimental study, is the basis for the recent growth of experimental biogerontology. As increasingly sophisticated studies provide greater understanding of what occurs in the aging brain and how these changes occur

This multi-chapter book focuses on one of the hottest topics in ageing research – the role of hormones in health and longevity, offering a comprehensive and up-to-date overview of their mechanistic roles in health, ageing and longevity. Hormones are an excellent system of communication between cells and tissues within an organism, and they coordinate a wide range of processes in biological systems, including neuroendocrine and immunological controls. The book offers insights into the latest significant advances in our understanding of the mechanisms of hormonal signaling that control a variety of processes involved in development and ageing. It is divided into four parts: Part I includes a review of the hundred-year history of hormones by the illustrious hormone biochemist Dr. J.R. Tata. Part II presents various chapters on the hormones involved in growth, stress and metabolism, while Part III addresses the hormones controlling cognition and rhythms in ageing processes. Lastly, Part IV discusses the hormones affecting reproduction, immunity and life span. It also explores the use of hormones as pharmaceuticals to maintain health in the elderly. It is a valuable resource for those working in the area of hormone signaling in general and in the field of ageing research in particular.

Clinical practice related to sleep problems and sleep disorders has been expanding rapidly in the last few years, but scientific research is not keeping pace. Sleep apnea, insomnia, and restless legs syndrome are three examples of very common disorders for which we have little biological information. This new book cuts across a variety of medical disciplines such as neurology, pulmonology, pediatrics, internal medicine, psychiatry, psychology, otolaryngology, and nursing, as well as other medical practices with an interest in the management of sleep pathology. This area of research is not limited to very young and old patientsâ€"sleep disorders reach across all ages and ethnicities. Sleep Disorders and Sleep Deprivation presents a structured analysis that explores the following: Improving awareness among the general public and health care professionals. Increasing investment in interdisciplinary somnology and sleep medicine research training and mentoring activities. Validating and developing new and existing technologies for diagnosis and treatment. This book will be of interest to those looking to learn more about the enormous public health burden of sleep disorders and sleep deprivation and the strikingly limited capacity of the health care enterprise to identify and treat the majority of individuals suffering from sleep problems.
