Filter by:The purpose of this study is to evaluate the efficacy and safety of TVP-1012 (0.5 mg or 1 mg/day) as an add-on to levodopa in Japanese participants with Parkinson's disease with wearing-off phenomenon.
The purpose of this study is to evaluate the efficacy and safety of TVP-1012 (1 mg/day) administered to Japanese patients with early Parkinson's disease.
The aim of this project is to evaluate the needs and provision of care for patients in the late stages of Parkinsonism and their carers in several European countries, to compare the effectiveness of different health and social care systems, and to lay the foundation for improved outcomes in this population. The investigators will undertake an in-depth assessment of patients and their care arrangements in a population recruited through networks in six European countries. The systems and procedures that are used in the provision of care will be reviewed through a systematic literature review, interviews and assessments of patients, carers and health care providers, and through a trial comparing assessment by a specialist with management suggestions, guidance and access to telephone advice to that of usual care. Through interviews, questionnaire assessment and review of current health-care and social care arrangement, the investigators will assess the needs, provision of care and use of health-care resources, and their impact on patient and carer outcomes in different countries. National and regional databases will also be interrogated to identify current practice and use of healthcare resources and drug usage. A systematic literature review of the evidence for effective management strategies, analysis of the study data, and evaluation of change in outcomes following specialist review will provide the basis for recommendations in the management of late stage Parkinsonism. The investigators will also evaluate potentially useful outcome measures for use in this patient group. In addition to charting the needs and current care provision for late stage Parkinsonism in different European countries, its cost and effectiveness, and an analysis of health-care and social care predictors of improved outcome, the project will produce a platform for the assessment of patients with late stage Parkinsonism, their current treatment and care provision, as well as guidelines on the management of this late disease phase.
Excessive free radical formation and depletion of the brain's primary antioxidant, glutathione, are established components of Parkinson's disease (PD) pathophysiology. While there is rationale for the therapeutic use of reduced glutathione (GSH) in PD, and even some preliminary evidence to suggest the use of GSH can lead to symptomatic improvement, obstacles surrounding currently employed delivery methods have hindered the clinical utility of this therapy. Intranasal GSH, (in)GSH, is a novel method of glutathione augmentation. The aim of this study is to evaluate whether 200 mg of (in)GSH results in measurable changes in brain glutathione concentrations, as measured by magnetic resonance spectroscopy (MRS) in 15 individuals with PD.
This project studies the impulsive side effects of common treatments for Parkinson's Disease. By learning how parts of the brain involved in Parkinson's encode information related to reward and motivation, the investigators will better understand the reasons why Parkinson's patients often suffer from compulsive gambling, hypersexuality, and repetitive tinkering ("punding"). These results may lead to the design of better methods of deep brain stimulation (DBS) that minimize the behavioral side effects of Parkinson's treatment.
The purpose of this study is to investigate the pharmacokinetics of levodopa, carbidopa, 3-OMD and ODM-104 after repeated doses of 3 levodopa formulations given in combination with carbidopa and ODM-104.
Single-centre, open-label, fixed-sequence design consisting of 2 periods separated by a washout period of at least 14 days.
Single-centre, open-label, randomised, two-way cross-over study consisting of 2 periods separated by a washout period of 14 days or more.
The purpose of this study is to evaluate the effects of low frequency deep brain stimulation on subthalamic nucleus neural synchrony. Low frequency stimulation does not improve the cardinal motor signs of Parkinson's disease, and may be beneficial only for gait and speech. This study will provide insight into what the effects of low frequency stimulation are on neural synchrony.
The purpose of this study is to evaluate our recently developed MRI reconstruction strategy for producing artifact-free neuro and abdominal MRI data. The new reconstruction strategies, including 1) REKAM and 2) MUSE, are capable of effectively removing motion-related artifacts resulting from global and local motion during neuro and free-breathing abdominal MRI scans, without modifying the MRI pulse sequences and protocols that are currently used in clinical scans. The study team aims to recruit 60 subjects across multiple challenge patient populations: 10 healthy young adults (age 20-30) and 10 healthy older adults (aged 50-70) for abdominal MRI, as well as 20 tremor dominant PD patients and 20 children (age 4-8) for brain MRI scans. There are no known risks in taking MRIs and a unique code will be assigned to each participant to protect their PHI.
