Clinical Studies and Therapies in Parkinson's Disease by Juan Segura-Aguilar Pdf

More than 50 years have passed since the use of L-dopa in the palliative treatment of Parkinson’s disease, but it remains the most common treatment despite inducing severe side effects such as dyskinesia after 4–6 years of use. Numerous preclinical investigations based on endogenous neurotoxin models have promised various therapies for Parkinson’s disease, but these efforts have failed when attempting to transfer these successful results to preclinical studies. Although several publications have warned of these failures, the scientific community remains mostly unaware, and there is a need to focus their efforts on potential therapeutics that can slow or halt development of the disease. Clinical Studies and Therapies in Parkinson’s Disease: Translations from Preclinical Models analyzes preclinical models based on exogenous neurotoxins and why they have failed. Neuroscientists, neurologists, and neuropharmacologists will benefit greatly from the book’s discussion of these newer models, their benefits, and the need for their implementation. This book also provides the basic concepts of dopamine metabolism for students taking courses in neurochemistry, neuroscience, neuropharmacology, biochemistry, and medicine. Reviews Parkinson's disease classification, pharmacological therapies, and nonmotor and motor symptoms Analyzes preclinical models of Parkinson’s disease therapies based on exogenous neurotoxins and why they have failed Reviews genetic preclinical models based on genetic mutations and endogenous neurotoxins Proposes a more physiological model directly related to the metabolism of dopaminergic neurons Provides the basic concepts and mechanisms of dopamine metabolism

The New Parkinson's Disease Treatment Book by J. Eric Ahlskog, PhD, MD Pdf

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.

The Right Therapy for Neurological Disorders by E. Beghi,G. Logroscino Pdf

Most neurological disorders are chronic and aging-related. With the increase of life expectancy their incidence and prevalence will grow in the decades to come, which in turn will increase the load on medical and social systems worldwide. There is thus a desperate need for successful preventive and therapeutic measures based on randomized clinical trials (RTCs) conducted by independent organizations. This book provides a compendium relating most of the principles of reliable RTCs to specific neurological diseases. Contributed by specialized neurologists, the articles touch on important aspects of RCTs with a clear critical approach, highlighting their limitations as well as giving recommendations for their planning and conducting to address the variable genotypic and phenotypic aspects of neurological conditions. Consideration is also given to combining the clinical impact of the study results with patients’ values and the interests of pharmaceutical companies. Neurologists involved in clinical trials will certainly benefit from this book, which should become a basic text for all neurological courses dealing with evidence-based neurology.

Levodopa pharmacokinetics -from stomach to brain by Maria Nord Pdf

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.
