Mechanisms In Parkinsons Disease

This comprehensive reference provides a detailed overview of current concepts regarding the cause of Parkinson's disease-emphasizing the issues involved in the design, implementation, and analysis of epidemiological studies of parkinsonism.

Parkinson’s Disease: Molecular Mechanisms Underlying Pathology explores the molecular pathways at the basis of the cellular defects connected to Parkinson’s disease, the second most common neurodegenerative disease, and the most common movement disorder. This book presents the latest research on the pathways and mechanisms that have been discovered to play a role in Parkinson's pathology. This focus on mechanisms rather than individual genes allows the contributors to elaborate on overlapping and joint functions of different causative genes. Readers will find descriptions of model systems that present parallels (and differences) between discoveries in different species, demonstrating the importance of multidisciplinary research that spans a broad array of technologies and model organisms. Written from both a cross-methodology and cross-species perspective, the book provides readers with the current state of knowledge on the molecular biology of Parkinson’s. Written by experts in the field that focus on pathways and mechanisms implicated in Parkinson’s pathology Draws parallels between multidisciplinary discoveries in different model organisms using an array of technologies Provides a cross-methodology and cross-species approach to understanding the molecular biology of Parkinson’s disease Includes approximately 25 color Illustrations and diagrams to explain concepts and models Focuses on key pathways and mechanisms (as opposed to model organism or gene) to provide a multidisciplinary approach to Parkinson’s disease

Parkinson's disease (PD) results primarily from the death of dopaminergic neurons in the substantia nigra. Current PD medications treat symptoms; none halt or retard dopaminergic neuron degeneration. The main obstacle to developing neuroprotective therapies is a limited understanding of the key molecular mechanisms that provoke neurodegeneration. The discovery of PD genes has led to the hypothesis that misfolding of proteins and dysfunction of the ubiquitin-proteasome pathway are pivotal to PD pathogenesis. Previously implicated culprits in PD neurodegeneration, mitochondrial dysfunction, and oxidative stress may also act in part by causing the accumulation of misfolded proteins, in addition to producing other deleterious events in dopaminergic neurons. Neurotoxin-based models have been important in elucidating the molecular cascade of cell death in dopaminergic neurons. PD models based on the manipulation of PD genes should prove valuable in elucidating important aspects of the disease, such as selective vulnerability of substantia nigra dopaminergic neurons to the degenerative process.

Balance Dysfunction in Parkinson’s Disease: Basic Mechanisms to Clinical Management presents the most updated information on a variety of topics. Sections help clinicians evaluate the types of balance control issues, dynamic balance dysfunction during turning, and the effects of medication, deep brain stimulation, and rehabilitation intervention on balance control. This book is the first to review the four main postural control systems and how they are affected, including balance during quiet stance, reactive postural adjustments to external perturbations, anticipatory postural adjustments in preparation for voluntary movements, and dynamic balance control during walking and turning. In addition, the book's authors summarize the effects of levodopa, deep brain stimulation, and rehabilitation intervention for each balance domain. This book is recommended for anyone interested in how and why balance control is affected by PD. Provides the first comprehensive review of research to date on balance dysfunctions in Parkinson's disease Discusses how to translate current neuroscience research into practice regarding neural control of balance Provides evidence on the effects of current interventions on balance control

It is an invaluable resource for neuroscientists, neurologists, and anyone in the field. Offers the most comprehensive coverage of a broad range of topics related to Parkinson's disease Serves as a foundational collection for neuroscientists and neurologists on the biology of disease and brain dysfunction Contains in each chapter an abstract, key facts, mini dictionary of terms, and summary points to aid in understanding Features preclinical and clinical studies to help researchers map out key areas for research and further clinical recommendations Serves as a "one-stop" source for everything you need to know about Parkinson’s disease

This newest volume of Advances in Neurobiology deals with the Neurochemistry of disease, with chapters covering both human diseases and animal “model” diseases.

Parkinson's Disease is the second most common neurodegenerative disorder affecting millions of people worldwide. In order to find neuroprotective strategies, a clear understanding of the mechanisms involved in the dopaminergic death of cells that progresses the disease is needed. Oxidative stress can be defined as an imbalance between the production of reactive species and the ability to detoxify them and their intermediates or by-products. Oxidative damage to lipids, proteins, and DNA has been detected in autopsies from individuals with Parkinson’s Disease and so links can be made between oxidative stress and Parkinson’s Disease pathogenesis. This book provides a thorough review of the mechanisms by which oxidative stress and redox signalling mediate Parkinson’s Disease. Opening chapters bring readers up to speed on basic knowledge regarding oxidative stress and redox signalling, Parkinson’s Disease, and neurodegeneration before the latest advances in this field are explored in detail. Topics covered in the following chapters include the role of mitochondria, dopamine metabolism, metal homeostasis, inflammation, DNA-damage and thiol-signalling. The role of genetics and gene-environment interactions are also explored before final chapters discuss the identification of potential biomarkers for diagnosis and disease progression and the future of redox/antioxidant based therapeutics. Written by recognized experts in the field, this book will be a valuable source of information for postgraduate students and academics, clinicians, toxicologists and risk assessment groups. Importantly, it presents the current research that might later lead to redox or antioxidant – based therapeutics for Parkinson’s disease.

The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.
