Understanding the role of sleep and the mechanisms at play in ageing are among the most exciting challenges in neuroscience. Although our understanding of the mechanisms governing sleep stages and their role in cognitive processes including memory functions is gradually increasing. most of the currently available data have been gathered in young adults. Still, substantial physiological changes in sleep are observed with increasing age, that may markedly impacts on daily functioning. This is why this Research Topic focuses on our current understanding of the impact of age-related changes in sleep architecture on various domains of cognition. The three editors Julie Carrier (Montréal, Canada), Philippe Peigneux (Brussels, Belgium) and Géraldine Rauchs (Caen, France) are specialized in various fields of sleep research. Here, they bring together an outstanding group of neuroscientist and clinical investigators engaged in the study of sleep, encompassing state-of-the-art studies of sleep disorders such as sleep apnoea or REM sleep behaviour disorder, studies assessing new treatments to improve sleep quality, together with experts in various domains of cognition such as vigilance, memory and dreams, in a perspective aimed at offering the interested reader a comprehensive view of the impact of age-related changes in sleep architecture on cognition.

Despite impressive advances in understanding sleep as a biological phenomenon and in understanding the nature of mental processes in the normal waking state, our knowledge of mental life during sleep remains extremely impoverished. The common identification of cognition with consciousness leaves the impression that little or no mental activity occurs during sleep. The present volume represents the Proceedings of the Arizona Conference on Sleep and Cognition, held in Tucson January 19-22, 1989. A principal concern of the conference was the implications of recent work on implicit memory and other aspects of information-processing outside of awareness for studies of cognitive processes during sleep, and the role of the sleep laboratory as a vehicle for studying various aspects of information processing outside of awareness, in the absence of the active deployment of attention. To this end, selected investigators in the area of sleep who have an interest in cognitive processes were brought together with their counterparts in the area of cognition who have an interest in sleep. We hope that one outcome of this meeting, and publication of the Proceedings, will be a new agenda for research on sleep that will carry investigators of both camps well into the 21st century.

What is the prevalence of insomnia in a particular age group, in men and women, or in Caucasians and African Americans? What is the average total sleep time among normal sleepers among these groups? How does the sleep of Caucasians and African Americans differ? These are just some of the questions addressed in The Epidemiology of Sleep. This new book presents the most detailed and comprehensive archive of normal and abnormal sleep patterns. Based on a landmark study supported by the National Institute on Aging, 772 subjects from a host of populations including men, women, and various age and ethnic groups, prepared detailed sleep diaries for a two-week period. The use of these sleep diaries yielded a plethora of data on such characteristics as normal sleep patterns, various forms of insomnia, fatigue, depression, anxiety, and daytime sleepiness differentiated by age, sex, and ethnicity. The results generated by these data, charted in the book's numerous tables and graphs, provide a critical methodological advance in the sleep literature. The Epidemiology of Sleep opens with an overview of the rationale and unique characteristics of the study. This is followed by a comprehensive review of the existing epidemiological literature on sleep. Chapter three presents a detailed description of the methods used in the survey followed by meticulous information on the epidemiology of normal and insomnia sleep, that is unparalleled in the literature. Chapter six provides an archive of sleep patterns among African Americans. The book concludes with a discussion and interpretation of the most interesting findings. This insightful study, coupled with the comprehensive review of the existing literature on the epidemiology of sleep, make this volume an invaluable resource for sleep researchers, clinicians, health and clinical psychologists, gerontologists, epidemiologists, and advanced students.

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.

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.

What are the boundary zones between normal aging and Alzheimer's disease (AD)? Are many elderly people whom we regard as normal actually in the early stages of AD? Alzheimer's disease does not develop overnight; the early phases may last for years or even decades. Recently, clinical investigators have identified a transitional condition between normal aging and and very early Alzheimer's disease that they have called mild cognitive impairment, or MCI. This term typically refers to memory impairment beyond what one would expect in individuals of a given age whose other abilities to function in daily life are well preserved. Persons who meet the criteria for mild cognitive impairment have an increased risk of progressing to Alzheimer's disease in the near future. Though many questions about this condition and its underlying neuropathology remain open, full clinical trials are currently underway worldwide aimed at preventing the progression from MCI to Alzheimer's disease. This book addresses the spectrum of issues involved in mild cognitive impairment, and includes chapters on clinical studies, neuropsychology, neuroimaging, neuropathology, biological markers, diagnostic approaches, and treatment. It is intended for clinicians, researchers, and students interested in aging and cognition, among them neurologists, psychiatrists, geriatricians, clinical psychologists, and neuropsychologists.

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.
