Système nerveux - Maladies ; Épidémiologie

The fine text provides a comprehensive and accessible overview of research methods for conducting epidemiologic and clinical research on neurologic conditions. It is aimed at neurologists, epidemiologists, and public health professionnals, as well as students of these disciplines. The book has three parts, each emphasizing the unique aspects of studying neurologic disorders. The first focuses on classic principles of epidemiologic and clinical research, including study design, sources of study bias, and methods for assessing the role of environmental and genetic factors in neurologic disorders. The second part covers each of the major neurologic disorders, with an emphasis on the methodologic aspects of studying these disorders and discussion of future research directions. The third part is devoted to clinical and translational research methods, including the design and conduct of clinical trials and prognostic studies, as well as the principles of health services research and evidence-based medicine. This textbook will give neurologists, epidemiologists, and their students the foundation for conducting rigorous epidemiologic and clinical research on neurologic disorders, and for interpreting the literature in this field.

Insomnie ; Épidémiologie ; Sommeil

This new book presents the most detailed and comprehensive rchive 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 2 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. Epidemiology of sleep opens with an overview of the rational and unique characteristics of the study. This is followed by a comprehensive review of the existing epidemiological literature on sleep. Chapter 3 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 6 provides an archive of sleep patterns among african americans. The book concludes with a discussion and interpretation of the most interesting findings. This insighful 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, gerontologist, epidemiologists, and advanced students.

Épidémiologie ; Erreurs systématiques

Evaluating the strenfth or persuasiveness of epidemiologic evidence ininherently challenging, both for those new to the field and for experienced researchers. There are myriad potential biases to consider, but little guidance about how to assess the likely impact on study results. This book offers a strategy for assessing epidemiologic study findings, explicitly describing the goals and products of epidemiolgic research in order to better evaluate its successes and limitations. The focus throughout is on practical tools for making optimal use of available data to assess whether hypothesized biases are operative and to anticipate concerns at the point of study design in order to ensure that needed information is generated, Specific tools for assessing the presence and impact of selection bias in both cohort and case-control studies, bias from non-response, confounding , exposure measurement error, disease measurement error, and random error, are identified and evaluated. The potential value of each approach and its limitations are discussed, using examples from te published literature. Such information should help those who generate and interpret epidemiolgic research to apply methodological principles more effectively to substantive issues, leading to a more accurate appraisal of the current evidence and greater clarity about research needs.
