Available in PDF, EPUB and Kindle. Book excerpt: Prior literature on the relationship between Body Mass Index (BMI) and cognition has been inconsistent. Thus, these relationships were examined in 1,023 participants (54.5%female) from the 1998 and 2005 waves of the Seattle Longitudinal Study (SLS). Participants were divided into two groups for the purpose of comparison, a middle-aged group (n=587; Age Range=40-64 years) and an older adult group (n=436; Age Range=65-93 years). The SLS records cognitive data in six abilities. Health variables included BMI, hypertension and smoking. Hierarchical multivariate regression analyses were used to examine relationships amongst change in BMI, cognition, hypertension, and smoking at both time points. Mean BMI for the study sample did not significantly change over time, but had a significant impact on predicting change in cognitive factor scores. A reduction in performance for change in verbal memory was identified with increased change in BMI for middle-aged adults, and an improvement in performance with change in verbal memory and change in spatial orientation with decreased change in BMI for older adults were found. Hypertension was not a significant mediator of the BMI- cognition relationships. However, smoking status was found to be a full mediator of the BMI-cognition relationship. Previous smoking at some time in the past explained the association between change in verbal memory and BMI over a seven-year period. The implications of this study yield new contributions to how increased BMI can negatively influence change in cognitive function in midlife adults, and how this association may change in older adulthood.
Download or read book Structural and Cognitive Correlates of Body Mass Index in Healthy Older Adults written by Jacob D. Bolzenius and published by . This book was released on 2014 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Obesity, commonly measured with body mass index (BMI), is associated with numerous deleterious health conditions and may be a modifier of age-related alterations in brain integrity. Research suggests that white matter integrity observed using diffusion tensor imaging (DTI) is altered with high BMI, but the integrity of specific tracts remains poorly understood. Additionally, no studies have examined fractional anisotropy (FA) of tract integrity in conjunction with neuropsychological evaluation with elevated BMI among older adults. It was hypothesized that elevated BMI would be independently associated with lower white matter integrity and cognitive performance. It was also hypothesized that age and BMI would interact in relation to measures of white matter integrity and cognitive performance. Sixty two healthy older adults aged 51 to 81 were evaluated using DTI and neuropsychological evaluation. Associations were examined between BMI, FA in tracts connecting frontal and temporal lobes, and cognitive ability in domains of executive function, processing speed, and memory. Hierarchical linear regressions were utilized to determine the impact of BMI on FA and cognitive function after accounting for demographics, followed by a test for a BMI by age interaction on FA and cognitive indices. Secondary analyses assessed the sensitivity of DTI diffusivity metrics to elevated BMI, and related tract FA to cognitive performance. After controlling for initial demographic relationships, elevated BMI was associated with lower FA in the uncinate fasciculus, though there was no evidence of an age by BMI interaction relating to FA in this tract. No relationships between BMI and cognition were observed. Secondary analyses did not suggest that DTI diffusivity metrics provide unique information about tract integrity related to high BMI. Overall, results suggest elevated BMI is associated with altered integrity of the uncinate fasciculus. This white matter tract connects frontal and temporal lobes and is involved in memory function. There was no evidence of an age by BMI interaction on FA of the uncinate fasciculus, and BMI did not relate to cognitive performance. Future studies should examine measures of cardiovascular health and systemic inflammation to identify factors influencing relationships between BMI and white matter integrity.
Download or read book Health and Cognition in Old Age written by Anja K. Leist and published by Springer. This book was released on 2014-07-14 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the aim of research on aging has shifted from prolonging life to fostering healthy and cognitively robust old age. In order to improve the quality of life of older people, we need to better understand cognitive aging as well as bodily aging. Health and Cognition in Old Age assembles the cream of research across varied medical, mental health, and social disciplines, and demonstrates how this knowledge can lead to improved outcomes for older people. The first half of this expert volume discusses biomedical and life course factors in aging, particularly as they affect cognition and well-being in later life. From there, effective solutions are the focus: interventions and care programs to improve mental functioning and general quality of life, and current policy and practice ideas in promoting healthy, active, and cognitively robust aging. Together, these diverse chapters offer a multi-faceted approach to understanding and modifying what was formerly the inevitable course of growing old. A sampling of the coverage: How the aging process affects the immune system. Occupational gerontology – work-related determinants of old age health and functioning. Social, behavioral, and contextual influences on cognitive function and decline. Lifestyle factors in the prevention of dementia. Understanding long-term care outcomes: conventional and behavioral economics. Social capital, mental well-being, and loneliness in older people. For gerontologists, sociologists, social workers, health psychologists, and others working to improve older people’s lives, Health and Cognition in Old Age brings expertise, versatility, and confidence to the table.

Download or read book Cognitive Aging written by Institute of Medicine and published by National Academies Press. This book was released on 2015-07-21 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Adult Cognition written by Timothy A. Salthouse and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: For some time now, the study of cognitive development has been far and away the most active discipline within developmental psychology. Although there would be much disagreement as to the exact proportion of papers published in developmental journals that could be considered cognitive, 50% seems like a conservative estimate. Hence, a series of scholarly books to be devoted to work in cognitive development is especially appropriate at this time. The Springer Series in Cognitive Development contains two basic types of books, namely, edited collections of original chapters by several authors, and original volumes written by one author or a small group of authors. The flagship for the Springer Series is a serial publication of the "advances" type, carrying the subtitle Progress in Cognitive Development Research. Volumes in the Progress sequence are strongly thematic, in that each is limited to some well-defined domain of cognitive-developmental research (e. g. , logical and mathematical development, semantic development). All Progress volumes are edited collections. Editors of such books, upon consultation with the Series Editor, may elect to have their works published either as contributions to the Progress sequence or as separate volumes. All books written by one author or a small group of authors will be published as separate volumes within the series. A fairly broad definition of cognitive development is being used in the selection of books for this series.

Download or read book How Healthy Are We written by Orville Gilbert Brim and published by University of Chicago Press. This book was released on 2004-01-15 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Childhood, adolescence, even the "twilight years" have been extensively researched and documented. But the vast terrain known as midlife—the longest segment of the life course—has remained uncharted. How physically and psychologically healthy are Americans at midlife? And why do some experience greater well-being than others? The MacArthur Foundation addressed these questions head-on by funding a landmark study known as "Midlife in the U.S.," or MIDUS. For the first time in a single study, researchers were able to integrate epidemiological, sociological, and psychological assessments, as well as innovative new measures to evaluate how work and family life influence each other. How Healthy Are We? presents the key findings from the survey in three sections: physical health, quality of life and psychological well-being, and the contexts (family, work) of the midlife. The topics covered by almost forty scholars in a wide variety of fields are vast, including everything from how health and well-being vary with socioeconomic standing, gender, race, or region of the country to how middle-aged people differ from younger or older adults in their emotional experience and quality of life. This health—the study measures not only health-the absence of illness—but also reports on the presence of wellness in middle-aged Americans. The culmination of a decade and a half of research by leading scholars, How Healthy Are We? will dramatically alter the way we think about health in middle age and the factors that influence it. Researchers, policymakers, and others concerned about the quality of midlife in contemporary America will welcome its insights. * Having a good life means having good relationships with others to almost 70% of those surveyed. Less than 40% mentioned their careers. * Reports of disruptive daily stressors vary by age, with young adults and those in midlife experiencing more than those in later adulthood. * Men have higher assessments of their physical and mental health than woman until the age of 60.

Download or read book Diet and Cognitive Decline written by Francesco Panza and published by Nova Publishers. This book was released on 2004 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The progressive ageing of the general population and the consequent increase of the number of old people has made the typical medical problems of aged people more frequently observed, and particularly the problems related to the ageing brain. This new book is an updated overview of relevant aspects of cognitive decline associated with ageing. Within the wide landscape of brain ageing the authors reconsider the role of the main predisposing factors and risk factors on the development of various form of mental decline, from mild cognitive impairment to dementia. The strength of this book is the large, updated overview of the most recent data of scientific literature regarding the role of genetic, metabolic and environmental factors on the predisposition and onset of cognitive decline. Particular attention is paid to the dietary micro- and macronutrients and to their possible role in the pathogenesis of the various form of dementigen disorders.
Download or read book Risk Factors in Depression written by Keith S. Dobson and published by Elsevier. This book was released on 2011-09-02 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Depression is one of the most common mental health disorders, affecting 14% of all people at some point in their lifetime. Women are twice as likely to become depressed as men, but beyond gender there are a variety of risk factors that influence the prevalence and likelihood of experiencing depression. Risk Factors in Depression consolidates research findings on risk factors into one source, for ease of reference for both researchers and clinicians in practice. The book divides risk factors into biological, cognitive, and social risk factors. This provides researchers with the opportunity to examine the interface among different theoretical perspectives and variables, and to look for the opportunity for more complex and explanatory models of depression. Allows reader to compare and contrast the relative states of development of different models and their databases Examines the predictive power of these models related to various phases of clinical depression, including onset, maintenance, and relapse Provides an examination of the therapeutic implications of comprehensive and integrative models of depression

This book was released on 2014-04-23 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hippocampus is one of the most intriguing structures of the human brain. Damage to this part causes symptoms ranging from transient disorders accompanied by tiny lesions to severely debilitating cognitive disorders with marked tissue loss. This publication provides a predominantly clinical approach to the complex workings of the hippocampus from different perspectives, ranging from basic principles to specific diseases. The first part of the book summarizes current knowledge regarding the structure and physiology of the hippocampus and establishes the ties to basic neuroscience. The second part deals with the function and assessment of the human hippocampus, including memory function, neuropsychological measures, and conventional and functional imaging studies. The chapters of the third part are devoted to the hippocampus in neurological disorders, e.g. the interaction between stress and memory function, and the pathological conditions of common as well as selected rare neurological diseases affecting the hippocampus. The book is highly recommended to clinical neurologists who wish to gain a broad understanding of this complex and fascinating organ in terms of basic principles, modern imaging findings, and specific diseases.
