Download or read book Neuroimaging in Dementia written by Frederik Barkhof and published by Springer Science & Business Media. This book was released on 2011-02-11 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: This up-to-date, superbly illustrated book is a practical guide to the effective use of neuroimaging in the patient with cognitive decline. It sets out the key clinical and imaging features of the various causes of dementia and directs the reader from clinical presentation to neuroimaging and on to an accurate diagnosis whenever possible. After an introductory chapter on the clinical background, the available "toolbox" of structural and functional neuroimaging techniques is reviewed in detail, including CT, MRI and advanced MR techniques, SPECT and PET, and image analysis methods. The imaging findings in normal ageing are then discussed, followed by a series of chapters that carefully present and analyze the key findings in patients with dementias. Throughout, a practical approach is adopted, geared specifically to the needs of clinicians (neurologists, radiologists, psychiatrists, geriatricians) working in the field of dementia, for whom this book will prove an invaluable resource.

This book was released on 2020 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Age-related cognitive decline and pathological brain changes are a widespread and growing public health issue. Several environmental factors, including engagement in physical activity and personality, have been shown to have potential protective effects in slowing cognitive decline and preserving healthy brain aging. However, the underlying mechanisms providing exercise- or personality-induced resilience to aging and disease remains largely unknown. Importantly, there has been an emergence of several novel biomarkers to study healthy brain aging and age-related neurodegenerative diseases including in vivo assessments of tau burden and brain metabolism via positron emission tomography (PET) imaging and neurofilament light chain (NfL), a marker of neurodegeneration, via Age-related cognitive decline and pathological brain changes are a widespread and growing public health issue. Several environmental factors, including engagement in physical activity and personality, have been shown to have potential protective effects in slowing cognitive decline and preserving healthy brain aging. However, the underlying mechanisms providing exercise- or personality-induced resilience to aging and disease remains largely unknown. Importantly, there has been an emergence of several novel biomarkers to study healthy brain aging and age-related neurodegenerative diseases including in vivo assessments of tau burden and brain metabolism via positron emission tomography (PET) imaging and neurofilament light chain (NfL), a marker of neurodegeneration, via blood-based biomarkers. During the first part of my thesis research, I examined these emerging biomarkers within healthy aging and AD cohorts at Washington University, in the Australian Imaging, Biomarkers, and Lifestyle (AIBL) cohort, and in the Dominantly Inherited Alzheimer Network (DIAN) observational study (Chapters 2 - 5). For the second part of my thesis research, I first used my new knowledge and experience with these biomarkers to characterize and determine the influence of physical activity on cerebral glucose metabolism (Chapter 6). Next, to better translate these findings to an exercise intervention in the future, I further completed a pilot study to determine feasibility and validity of performing a submaximal exercise protocol in a diverse US population (Chapter 7). For the third part of my thesis research, I discovered a cross-sectional association between personality traits and neurofibrillary tangle pathology. Taken together, the results from my thesis suggest utility in all three emerging biomarkers examined (tau-PET, blood-based NfL, and multi-tracer brain metabolism PET) for monitoring and understanding complex changes associated with brain aging and disease. Additionally, this thesis research adds to the current understanding of the potential role of increased physical activity in preservation of glycolytic metabolism in the aging brain and increased risk of AD-related tau pathophysiology in neurotic personality traits. Further research extending these findings to longitudinal studies are needed to help determine directionality of the observed effects.

Download or read book Heterogeneity in Brain Aging written by Jasmine Alexandra Nettiksimmons and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Alzheimer's disease (AD) is a neurodegenerative disease that appears in the elderly and is characterized by cognitive impairment, specifically in memory. Due to shifting demographics and improving medical technology resulting in longer lifespans, the prevalence of AD and other types of dementia is on the rise. While AD has been recognized for over a century, the scientific understanding of the biological pathways involved is still fragmentary. Definitive diagnosis of AD requires examination of the brain in an autopsy, which complicates studying the disease in living patients. A wide variety of cognitive tests exist, but intra- and inter-person variability in test-taking ability along with overlapping symptomology between different types of dementia makes precise characterization of disease more difficult. In recent years, there has been substantial development in the use of a variety of different types of biomarkers to understand AD. AD biomarkers include regional brain volume measures from MRI, measures of regional metabolism with FDG-PET, protein levels in cerebrospinal fluid (CSF), along with others. The Alzheimer's Disease Neuroimaging Initiative (ADNI) was a large, prospective study of AD biomarkers funded by a public/private partnership. Starting in 2003, ADNI enrolled approximately 800 subjects, 200 with AD, 400 with mild cognitive impairment (MCI), and 200 who were cognitively normal, and followed each group longitudinally over 2-3 years collecting repeated clinical and biological data. Although there are many biomarkers that are associated with AD, none of them is sufficiently sensitive or specific enough to be used as a diagnostic test; for most biomarkers, there is substantial overlap in distribution between the three diagnostic groups. This research focused on examining multivariate structure in AD biomarkers using unsupervised cluster analysis in an effort to understand whether subgroups exist which have clinical implications. The biomarker profiles found in both the cognitively normal controls and MCI subjects were highly informative regarding the degree and type of biological heterogeneity accompanying the relative clinical homogeneity in each diagnostic group. A small subgroup of the ADNI controls had a biomarker profile clearly characteristic of the early stages of AD at baseline, even though they were still cognitively normal. Over time, this group experienced more rapid cognitive decline than the rest of the controls. Another large subgroup of the normal controls demonstrated marked atrophy in multiple brain regions, but lacked the CSF profile characteristic of AD. Vascular damage was examined as a possible explanation, and in fact, this group was consistently associated with a variety of vascular risk factors and also exhibited significantly more cognitive decline than the typical/healthy normal cluster. There was a great deal of biological heterogeneity in the MCI group, with two of the four clusters exhibiting biomarker patterns that are not well described by the prevailing theory of AD. Finally, structurally missing data in ADNI provoked an exploration into the possibilities of using imputation techniques for clustering. Although imputation is very commonly used in regression, there is virtually no literature on its use with other statistical techniques. The simulation performed here indicated that both single and multiple imputation methods have the capacity to perform very well in a clustering context, even when the clusters are not compact and well-separated.

Download or read book The Cambridge Handbook of Cognitive Aging written by Ayanna K. Thomas and published by Cambridge University Press. This book was released on 2020-05-28 with total page 1019 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decades of research have demonstrated that normal aging is accompanied by cognitive change. Much of this change has been conceptualized as a decline in function. However, age-related changes are not universal, and decrements in older adult performance may be moderated by experience, genetics, and environmental factors. Cognitive aging research to date has also largely emphasized biological changes in the brain, with less evaluation of the range of external contributors to behavioral manifestations of age-related decrements in performance. This handbook provides a comprehensive overview of cutting-edge cognitive aging research through the lens of a life course perspective that takes into account both behavioral and neural changes. Focusing on the fundamental principles that characterize a life course approach - genetics, early life experiences, motivation, emotion, social contexts, and lifestyle interventions - this handbook is an essential resource for researchers in cognition, aging, and gerontology.
Download or read book Neuroanatomy and Pathology of Sporadic Alzheimer s Disease written by Heiko Braak and published by Springer. This book was released on 2014-12-11 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: As indicated by its title, this monograph deals chiefly with morphologically recognizable deviations from the normal anatomical condition of the human CNS. The AD-associated pathology is illustrated from its beginnings (sometimes even in childhood) to its final form, which is reached late in life. The AD process commences much earlier than the clinically recognizable phase of the disorder, and its timeline includes an extended preclinical phase. The further the pendulum swings away from the symptomatic final stages towards the early pathology, the more obvious the lesions become, although from a standpoint of severity they are more unremarkable and thus frequently overlooked during routine neuropathological assessment. For this reason, the authors deal with the hallmark lesions in the early phases of the AD process in considerable detail
Download or read book A Multidisciplinary Approach to Capability in Age and Ageing written by Hanna Falk Erhag and published by Springer Nature. This book was released on 2022-01-10 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Heterogeneity of Alzheimer s Disease written by Francois Boller and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term "Alzheimer's disease" is currently used to refer to senile and also presenile dementia, but the heterogeneity of this disorder is demonstrated in many of its aspects. This is of great theoretical interest, and with the appearance of new therapeutic interventions, it may well also start to have very significant practical importance. To shed some light on the debate, the Fondation Ipsen organized an international symposium which took place on April 6, 1992. This volume contains the proceedings of this meeting, which was attended by researchers in epidemiology, clinical neurology and geriatrics, neuropsychology, neuropathology, molecular biology, and genetics.
