Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: Patients with Parkinson's disease (PD) are known to suffer from motor symptoms of the disease, but they also experience non-motor symptoms (NMS) that are often present before diagnosis or that inevitably emerge with disease progression. The motor symptoms of Parkinson's disease have been extensively researched, and effective clinical tools for their assessment and treatment have been developed and are readily available. In contrast, researchers have only recently begun to focus on the NMS of Parkinson's Disease, which are poorly recognized and inadequately treated by clinicians. The NMS of PD have a significant impact on patient quality of life and mortality and include neuropsychiatric, sleep-related, autonomic, gastrointestinal, and sensory symptoms. While some NMS can be improved with currently available treatments, others may be more refractory and will require research into novel (non-dopaminergic) drug therapies for the future. Edited by members of the UK Parkinson's Disease Non-Motor Group (PD-NMG) and with contributions from international experts, this new edition summarizes the current understanding of NMS symptoms in Parkinson's disease and points the way towards future research.

Available in PDF, EPUB and Kindle. Book excerpt: The study of the brain continues to expand at a rapid pace providing fascinating insights into the basic mechanisms underlying nervous system illnesses. New tools, ranging from genome sequencing to non-invasive imaging, and research fueled by public and private investment in biomedical research has been transformative in our understanding of nervous system diseases and has led to an explosion of published primary research articles. Diseases of the Nervous System, Second Edition, summarizes the current state of basic and clinical knowledge for the most common neurological and neuropsychiatric conditions. In a systematic progression, each chapter covers either a single disease or a group of related disorders ranging from static insults to primary and secondary progressive neurodegenerative diseases, neurodevelopmental illnesses, illnesses resulting from nervous system infection and neuropsychiatric conditions. Chapters follow a common format and are stand-alone units, each covering disease history, clinical presentation, disease mechanisms and treatment protocols. Dr. Sontheimer also includes two chapters which discuss common concepts shared among the disorders and how new findings are being translated from the bench to the bedside. In a final chapter, he explains the most commonly used neuroscience jargon. The chapters address controversial issues in current day neuroscience research including translational research, drug discovery, ethical issues, and the promises of personalized medicine. This new edition features new chapters on Pain and Addiction to highlight the growing opioid crisis and the ethical issue of prescriptions drug abuse. This book provides an introduction for course adoption and an introductory tutorial for students, scholars, researchers and medical professionals interested in learning the state of the art concerning our understanding and treatment of diseases of the nervous system. Each chapter includes suggested further readings and/or journal club recommendations. - 2016 PROSE Award winner of the Best Textbook Award in Biological and Life Sciences - Provides a focused tutorial introduction to the core diseases of the nervous system - Includes comprehensive introductions to Stroke, Epilepsy, Alzheimer's Disease, Parkinson's Disease, Huntington's Disease, ALS, Head and Spinal Cord Trauma, Multiple Sclerosis, Brain Tumors, Depression, Schizophrenia and many other diseases of the nervous system - Covers more than 40 diseases from the foundational science to the best treatment protocols - Includes discussions of translational research, drug discovery, personalized medicine, ethics, and neuroscience - New Edition features two new chapters on Pain and Addiction

This book was released on 2007-11-10 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parkinson’s Disease and Nonmotor Dysfunction fills a major gap in the current rapidly growing body of knowledge concerning Parkinson’s disease. Drs. Pfeiffer and Bodis-Wollner have correctly perceived that many nonmotor features of Parkinson’s disease are given insufficient attention in the medical literature. Unfortunately, they are often also given insufficient attention by the practicing neurologists who see these patients. As recently pointed out, there is clearly much more to Parkinson’s disease than depletion of the nigrostriatal dopamine system (1). Parkinson’s disease (not just m- tiple system atrophy) is a multisystem disorder, both pathologically and in its clinical manifestations. This is clearly true for the various motor system abnormalities, which are not fully corrected by dopamine replacement therapy strategies, but also for the nonmotor system abnormalities that are the subject of this volume. Although recently there has been increased awareness of the cognitive, psychiatric, and sleep disorders commonly associated with Parkinson’s disease, many of their manifestations remain under-recognized and their importance in managing patients is underestimated. Even less attention is paid to the myriad of other nonmotor disturbances that plague these patients. For example, among the autonomic disorders, although orthostatic hypotension is well recognized, it is usually attributed to dopaminergic medications rather than to effects of the underlying disease. Urologic disorders are also very familiar in these patients, but may not be properly understood or well managed.

This book was released on 2015-08-03 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamental guide to the most effective treatments for Parkinson's Disease, from a Mayo Clinic doctor with thirty years of clinical and research experience. In this second edition follow-up to the extremely successful first edition, Dr. Ahlskog draws on thirty years of clinical experience to present the definitive guide to dealing with all aspects of Parkinson's Disease, from treatment options and side effects to the impact of the disease on caregivers and family. Dr. Ahlskog's goal is to educate patients so that they can better team up with their doctors to do battle with the disease, streamlining the decision-making process and enhancing their treatment. To do this, Dr. Ahlskog offers a gold mine of information, distilled from his years of experience treating people with Parkinson's at the Mayo Clinic. In addition to providing a comprehensive account of Parkinson's medications, this book also examines additional aspects of treatment, such as the role of nutrition, exercise, and physical therapy. Although many commendable texts have been written on the subject of Parkinson's Disease, their discussions of treatment have not been in depth. Dr. Ahlskog sifts through aspects of the disease in order to give the reader a comprehensive sense of Parkinson's and the best available treatment options. With a broader understanding of the disease and the available options, patients are able to make more informed choices, and doctors are able to provide more tailored care. This book delivers hopeful, helpful, and extensive information to all parties concerned: patients, caregivers, and doctors. The ultimate guide to symptoms and treatment, this thoroughly updated second edition is the first place patients should turn for reliable, easy-to-grasp information on Parkinson's Disease.

Book excerpt: The field of movement disorders is relatively broad, encompassing disorders of increased movement, such as tremors, dystonia, and tics, to disorders characterized by a paucity of movement, such as Parkinson's disease. Our understanding of the pathogenic mechanisms and our treatment options are expanding at a rapid pace. This expansion ranges from the medical and surgical advances in treating Parkinson's disease to the flood of genetic abnormalities that have now been found to cause various movement disorders. Although many patients are seen by the movement disorders specialist in neurology clinics around the country, most of these patients receive their followup care from a primary care physician or "general" neurologist who must be versed in the character istics and treatment plans of this diverse group of disorders. The major goal of Parkinson's Disease and Movement Disorders: Diagnosis and Treatment Guidelines for the Practicing Physician is to distill this immense amount of information and to educate the practitioner about the many facets of the movement disorders field. We believe that this book fills a large void, since most texts on movement disorders are more detailed and geared toward the specialist. We have asked the chapter authors to emphasize the clinical characteristics of each disorder, discuss the differential diagnosis and the diagnostic testing, and then outline the various treatment options, as if they were teaching during a preceptorship in their clinic.

Available in PDF, EPUB and Kindle. Book excerpt: Most textbooks on neurodegenerative disorders have used a classification scheme based upon either clinical syndromes or anatomical distribution of the pathology. In contrast, this book looks to the future and uses a classification based upon molecular mechanisms, rather than clinical or anatomical boundaries. Major advances in molecular genetics and the application of biochemical and immunocytochemical techniques to neurodegenerative disorders have generated this new approach. Throughout most of the current volume, diseases are clustered according to the proteins that accumulate within cells (e.g. tau, α-synuclein and TDP-43) and in the extracellular compartments (e.g. β-amyloid and prion proteins) or according to a shared pathogenetic mechanism, such as trinucleotide repeats, that are a feature of specific genetic disorders. Chapters throughout the book conform to a standard lay-out for ease of access by the reader and are written by a panel of International Experts Since the first edition of this book, major advances have been made in the discovery of common molecular mechanisms between many neurodegenerative diseases most notably in the frontotemporal lobar degenerations (FTLD) and motor neuron disease or amyotrophic lateral sclerosis. This book will be essential reading for clinicians, neuropathologists and basic neuroscientists who require the firm up-to-date knowledge of mechanisms, diagnostic pathology and genetics of Neurodegenerative diseases that is required for progress in therapy and management.

This book was released on 2019-01-07 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parkinson’s disease (PD) is one of the most common neurodegenerative disorders and it is caused by a loss of dopamine (DA) producing neurons in the basal ganglia in the brain. The PD patient suffers from motor symptoms such as tremor, bradykinesia and rigidity and treatment with levodopa (LD), the precursor of DA, has positive effects on these symptoms. Several factors affect the availability of orally given LD. Gastric emptying (GE) is one factor and it has been shown to be delayed in PD patients resulting in impaired levodopa uptake. Different enzymes metabolize LD on its way from the gut to the brain resulting in less LD available in the brain and more side effects from the metabolites. By adding dopa decarboxylase inhibitors (carbidopa or benserazide) or COMT-inhibitors (e.g. entacapone) the bioavailability of LD increases significantly and more LD can pass the blood-brain-barrier and be converted to DA in the brain. It has been considered of importance to avoid high levodopa peaks in the brain because this seems to induce changes in postsynaptic dopaminergic neurons causing disabling motor complications in PD patients. More continuously given LD, e.g. duodenal or intravenous (IV) infusions, has been shown to improve these motor complications. Deep brain stimulation of the subthalamic nucleus (STN DBS) has also been proven to improve motor complications and to make it possible to reduce the LD dosage in PD patients. In this doctoral thesis the main purpose is to study the pharmacokinetics of LD in patients with PD and motor complications; in blood and subcutaneous tissue and study the effect of GE and PD stage on LD uptake and the effect of continuously given LD (CDS) on LD uptake and GE; in blood and cerebrospinal fluid (CSF) when adding the peripheral enzyme inhibitors entacapone and carbidopa to LD infusion IV; in brain during STN DBSand during oral or IV LD treatment. To conclude, LD uptake is more favorable in PD patients with less severe disease and GE is delayed in PD patients. No obvious relation between LD uptake and GE or between GE and PD stage is seen and CDS decreases the LD levels. Entacapone increases the maximal concentration of LD in blood and CSF. This is more evident with additional carbidopa and important to consider in avoiding high LD peaks in brain during PD treatment. LD in brain increases during both oral and IV LD treatment and the DA levels follows LD well indicating that PD patients still have capacity to metabolize LD to DA despite probable pronounced nigral degeneration. STN DBS seems to increase putaminal DA levels and together with IV LD treatment also increases LD in brain possibly explaining why it is possible to decrease LD medication after STN DBS surgery. Parkinsons sjukdom (PS) är en av de vanligaste s.k. neurodegenerativasjukdomarna och orsakas av förlust av dopamin(DA)producerande nervceller i hjärnan. Detta orsakar motoriska symptom såsom skakningar, stelhet och förlångsammade rörelser. Levodopa (LD) är ett ämne, som kan omvandlas till DA i hjärnan och ge symptomlindring och det är oftast förstahandsval vid behandling av patienter med PS. Flera faktorer påverkar tillgängligheten av LD, bl.a. den hastighet som magsäcken tömmer sig med och denna verkar förlångsammad hos personer med PS vilket ger sämre tillgänglighet av LD i blodet och därmed i hjärnan. LD bryts även ner i hög grad av olika enzym ute i kroppen vilket leder till mindre mängd LD som hamnar i hjärnan och till fler nedbrytningsprodukter som orsakar biverkningar. Tillägg av enzymhämmare leder till ökad mängd LD som kan nå hjärnan och omvandlas till DA. Det anses viktigt att undvika höga toppar av LD i hjärnan då dessa verkar bidra till utvecklandet av besvärliga motoriska komplikationer hos patienter med PS. Om LD ges mer kontinuerligt, exempelvis som en kontinuerlig infusion in i tarmen eller i blodet, så minskar dessa motoriska komplikationer. Inopererande av stimulatorer i vissa delar av hjärnan (DBS) har också visat sig minska dessa motoriska komplikationer och även resultera i att man kan minska LD-dosen. Huvudsyftet med den här avhandlingen är att studera LD hos patienter med PS; i blod och fettvävnad då LD ges i tablettform och se om det finns något samband med LD-upptag och hastigheten på magsäckstömningen (MT) och om kontinuerligt given LD påverkar LD-upptaget eller MT; i blod och i ryggmärgsvätska då enzymhämmarna entakapon och karbidopa tillsätts LD; i hjärna vid behandling med DBS och då LD ges både som tablett och som infusion i blodet. Sammanfattningsvis kan vi se att LD-upptaget är mer gynnsamt hos patienter med PS i tidigare skede av sjukdomens komplikationsfas. MT är förlångsammad hos patienter med PS och det är inget tydligt samband mellan LD-upptag och MT eller mellan MT och sjukdomsgrad. Kontinuerligt given LD minskar LDnivåerna. Enzymhämmaren entakapon ökar den maximala koncentrationen av LD i blod och ryggmärgsvätska och effekten är mer tydlig vid tillägg av karbidopa vilket är viktigt att ta i beaktande vid behandling av PS för att undvika höga toppar av LD i hjärnan. LD ökar i hjärnan då man behandlar med LD i tablettform och som infusion i blodet och DA-nivåerna i hjärnan följer LD väl vilket visar på att patienter med PS fortfarande kan omvandla LD till DA trots trolig uttalad brist av de DA-producerande nervcellerna i hjärnan. DBS verkar öka DA i vissa områden i hjärnan och tillsammans med LD-infusion i blodet verkar det även öka LD i hjärnan och det kan förklara varför man kan sänka LDdosen efter DBS-operation.
