There is a wide scope of clinical phenomenology in Alzheimers disease, regarding the age of onset, presenting features, rate of progression and appearance of other clinical manifestation. Although clinical appearance and neuropathological hallmarks have been defining AD since its first description, major factors which trigger pathology are still unknown. The role of comorbidity is discussed controversially. Important environmental risk factors in AD development are continuous stress, low education and cardiovascular risk factors such as alcohol intake, smoking, hypertension. The role of lipids and cholesterol has been recognized, but the relevant pathogenetic steps are still to be identified. There is an urgent need to understand molecular disease pathogenesis in order to develop early therapeutic targets for the disease.
Alzheimer's dementia (AD) affects 6 million Europeans with 10% of people over age 65 and more than a quarter over 85. Given the steady aging of European societies, dementia and cognitive decline have developed into a major health problem with an enormous socioeconomic impact for patients, their families and caregivers, national health care systems, and society. Without any means to prevent or delay disease onset, the number of people with dementia is predicted to double by 2030 and triple by 2050. There is an urgent need for innovative strategies to increase understanding of pathological events that would translate into the development of successful prevention or, possibly, novel treatment strategies. Progresses in understanding pathological events in AD have been possible by using cell cultures, genetically modified organisms and animal models that lack the complexity of events occurring in humans. We need to overcome this limitation also by using data from humans - for studying pathological pathways in AD in a multidisciplinary setting.
The Clinical Spectrum of Alzheimer's Disease: The Charge Toward Comprehensive Diagnostic and Therapeutic Strategies is highly informative and current. Acknowledged experts in the field critically review both standard and under-appreciated clinical, behavioral, epidemiological, genetic, and neuroimaging attributes of Alzheimer's disease. The collection covers diverse topics of interest to clinicians and researchers alike. Experienced professionals and newcomers to the field will benefit from the read. The strengths and weaknesses of current clinical, non-invasive, neuro-imaging, and biomarker diagnostic approaches are explained. The perspectives give fresh insights into the process of neurodegeneration. Readers will be enlightened by the evidence that the neural circuits damaged by neurodegeneration are much broader than conventionally taught, suggesting that Alzheimer's could be detected at earlier stages of disease by utilizing multi-pronged diagnostic approaches. This book inspires renewed hope that more effective treatments could be developed based upon the expanding list of potential therapeutic targets.
This volume provides a comprehensive understanding of the biology of dementias, including information on advancements in the way these disorders are perceived and studied. From earlier assumptions that cognitive deficits were simply age related, this handbook progresses into complex discussions of the diseases that affect the cortex of the human brain. Clinicians will find extensive diagnostic and research perspectives on a variety of interesting topics, including neuropathology, physiopathology, biology, clinics, and imaging information on all, or most, of the dementing disorders currently known. In addition, chapters devoted to legal and ethical issues give practitioners and health care wo...
Communicating the nature and consequences of environmental and health risks is still one of the most problematic areas of public policy in Western democracies. "Mad Cows and Mother's Milk" outlines the crucial role of risk management in dealing with public controversies and analyses risk communication practice and malpractice to provide a set of lessons for risk managers and communicators. This second edition adds new case studies on mad cow disease in North America, climate change, and genetics technologies. The first of the new case studies brings the story of the Bovine Spongiform Encephalopathy (BSE) outbreak in the United Kingdom in the 1980s up-to-date. Mad cow disease is still being d...
The domain of Communication Disorders has grown exponentially in the last two decades and has come to encompass much more than audiology, speech impediments and early language impairment. The realization that most developmental and learning disorders are language-based or language-related has brought insights from theoretical and empirical linguistics and its clinical applications to the forefront of Communication Disorders science. The current handbook takes an integrated psycholinguistic, neurolinguistic, and sociolinguistic perspective on Communication Disorders by targeting the interface between language and cognition as the context for understanding disrupted abilities and behaviors and providing solutions for treatment and therapy. Researchers and practitioners will be able to find in this handbook state-of-the-art information on typical and atypical development of language and communication (dis)abilities across the human lifespan from infancy to the aging brain, covering all major clinical disorders and conditions in various social and communicative contexts, such as spoken and written language and discourse, literacy issues, bilingualism, and socio-economic status.
This book contains selected peer-reviewed chapters that cover novel information on cognitive disorders and updated information on dementias written by international researchers. In this project, we discuss the effect of metabolic disorders on the development of cognitive disorders in patients with type 1 diabetes mellitus. In another chapter, the authors highlight the usability of an assistive software application developed for patients with dementia. On the other hand, an extensive review of novel information on different types of dementia is made. This chapter covers the novel aspect of dementia without ignoring its foundation. Therefore, apart from classic issues that cannot be missed in ...
The cellular prion protein (PrPC) is expressed as a cell surface protein mainly in the central and peripheral nervous system. The discovery that prions are infectious agents changed the concept of protein synthesis in modern biology and built a bridge between the genesis of infectious and genetic diseases. This book discusses the normal function of the PrPC and its modulatory role in synaptic mechanisms. It describes the pathophysiological processes that accompany TSE - neurotoxicity, loss of anti-inflammatory protective function, neuronal death including prion-induced autophagy and apoptosis, and accumulation of PrPSc in the cytoplasm of neurons. Another aspect outlined here is that some prion diseases show strain variations that determine their development, demonstrating their key role in the development and progression of TSE.
