Download or read book Levodopa pharmacokinetics from stomach to brain written by Maria Nord and published by Linköping University Electronic Press. 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.
Download or read book Non Motor Symptoms of Parkinson s Disease written by K. Ray Chaudhuri and published by Oxford University Press, USA. This book was released on 2014 with total page 517 pages. 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.

Download or read book Mucuna versus Parkinson treatment with natural levodopa written by Rafael González Maldonado and published by Rafael González Maldonado. This book was released on 2014-08-19 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Mucuna pruriens” is a bean that grows in the tropics. It is very rich in natural levodopa that is better tolerated and more potent than the synthetic levodopa in Sinemet or Stalevo. Two prestigious neurologists have patented extracts of mucuna seeds as a treatment for Parkinson's. Meanwhile, patients have recorded their positive experiences with mucuna; they buy it online (no prescription needed) and use it in secrecy without consulting their neurologist. Neither the patients nor the doctors (most of them) have clear ideas about this plant, its ingredients (not only levodopa), the proportions in which it is absorbed, or how to manage it. "Mucuna versus Parkinson: Natural Levodopa Treatment" is so far the most complete and up-to-date monograph on the subject, it describes the theoretical and practical approaches to the use of this plant as a treatment option for Parkinson's disease. Also included are more than one hundred of references.

Download or read book Marsden s Book of Movement Disorders written by Ivan Donaldson and published by Oxford University Press. This book was released on 2012-03-29 with total page 1512 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the final work of the late Professor C. David Marsden, who was the most influential figure in the field of movement disorders, in terms of his contributions to both research and clinical practice, in the modern era. It was conceived and written by David Marsden and his colleague at the Institute of Neurology, Prof. Ivan Donaldson. It was their intention that this would be the most comprehensive book on movement disorders and also that it would serve as the 'clinical Bible' for the management of these conditions. It provides a masterly survey of the entire topic, which has been made possible only by vast laboratory and bedside experience. Marsden's Book of Movement Disorders covers the full breadth of movement disorders, from the underlying anatomy and understanding of basal ganglia function to the diagnosis and management of specific movement disorders, including the more common conditions such as Parkinson's Disease through to rare, and very rare conditions such as Niemann-Pick disease. Chapters follow a structured format with historical overviews, definitions, clinical features, differential diagnosis, investigations and treatment covered in a structured way. It is extensively illustrated with many original photographs and diagrams of historical significance. Among these illustrations are still images of some original film clips of some of Dr. Marsden's patients published here for the first time. Comprehensively referenced and updated by experts from the Institute of Neurology at Queen Square, this book is a valuable reference for, not just movement disorder specialists and researchers, but also for clinicians who care for patients with movement disorders.

Download or read book Run in the Light written by John Mitrofanis and published by Morgan & Claypool Publishers. This book was released on 2019-08-05 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parkinson's disease is a neurological disorder with cardinal motor signs of resting tremor, bradykinesia and lead-pipe rigidity. In addition, many patients display non-motor symptoms, including a diminished sensation of smell, gastrointestinal problems, various disorders of sleep and some cognitive impairment. These clinical features - particularly the motor signs - manifest after a progressive death of many dopaminergic neurones in the brain. Although currently available, conventional therapies can reduce the signs of the disease, the progression of this neuronal death has proved difficult to slow or stop, and the condition is relentlessly progressive. Hence, there is a real need to develop a treatment that is neuroprotective, one that slows the pathology of the disease effectively. At present, there are several neuroprotective therapies in the experimental pipeline, but these are for the patients of tomorrow. This book focuses on two therapies that are readily available for the patients of today. They involve the use of exercise and light (i.e. photobiomodulation, the use of red to infrared light therapy (λ=600-1070nm) on body tissues). The two therapies are tied together in several ways. First, in animal models of Parkinson's disease, they each have been shown to offer the key feature of neuroprotection, stimulating a series of built-in protective mechanisms within the neurones, that helps their survival, to self-protect and/or self-repair. There are also some promising indications of neuroprotection and many beneficial outcomes in parkinsonian patients. Further, both exercise and light therapies are similar in that they are non-invasive and safe to use, with no known adverse side-effects, making their combination with the conventional therapies, such as dopamine replacement drug therapy and deep brain stimulation, all the more feasible. Given the heterogeneity of Parkinson's disease in humans, tackling the condition from a range of different angles - with a number of different therapies - would only serve to enhance the positive outcomes. This book considers the use of exercise and light therapies, proposing that they have the potential to make a powerful "dynamic duo", offering a most effective neuroprotective treatment option to patients.

Available in PDF, EPUB and Kindle. Book excerpt: Conventional management of Parkinson's disease (PD) is limited. The pharmaceutical and surgical options that are available have significant side effects and only correct symptoms for a limited period of time. Even with the best conventional treatment, the disease progresses and becomes severely disabling. No existing conventional therapies that the progress of the disease; available medicines only treat symptoms temporarily. Conventional medicine views the course of the disease as "progressive" and "irreversible." Many patients, who are only partially satisfied with conventional medicine, seek alternative and complementary options in an attempt to slow, stop, or reverse the disease process. This book has several functions:- It is a science-based reference manual.- It is inspiring and empowering to patients.- It is educational for both patients and neurologists.- It is entertaining.- It fosters an understanding between conventional and complementary providers.Chapters on , Alpha-Lipoic Acid, Aluminum, Antioxidants, Beta-carotene, Calorie Restriction, Carnitine, Chelation, Cholesterol, Choline, Coenzyme Q-10, Constipation, Creatine, Curcumin (Turmeric), Dairy, DHA (fish oil), Fava Beans, Glutathione, H. pylori (Helicobacter pylori), Homocysteine, Iron, Manganese, Marijuana (Cannabis sativa), Mucuna pruriens, Velvet bean, Cowhage, Niacin, Tea, Vitamin B6, Vitamin D, and other topics.

Download or read book Rethinking Parkinson s Disease written by John C Coleman and published by Hybrid Publishers. This book was released on 2020-10-08 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: John Coleman was diagnosed with Parkinson's disease while studying to be a naturopath, and banished all the frustrating symptoms of this cruel condition from his body ... naturally! His new book equips those diagnosed with the knowledge needed to reverse their Parkinson's disease symptoms and even recover, using completely natural means. Rethinking Parkinson's Disease traces known pathways leading to a diagnosis of Parkinson's disease, together with strategies to reverse each pathway. It includes the best evidence from Western allopathic medicine and complementary/alternative medicine in discovering how and why people with Parkinson's develop symptoms, the diagnostic process, standard treatments and prognoses offered by expert practitioners, and ongoing research. The book presents strategies that have been shown, clinically or in research, to improve the health of people with Parkinson's, with the possibility of reversing symptoms. A major section of this work details strategies to create wellness, many available to patients at little or no cost. There are sections on symptom control, complementary medical treatments and therapies to avoid. The book is aimed primarily at people with Parkinson's, families and supporters, and may be used as a self-help book, including advice on building a team of supportive practitioners. There are also suggestions and advice for both Western allopathic medicine and complementary/alternative medicine practitioners to enhance their care of patients with a Parkinson's disease diagnosis, so it may be used as a handbook for practitioners wishing to move away from the standard conservative view of Parkinson's disease as an "incurable" disease.
