Filter by:The objective of this experiment is: - Primary: To determine the effects of tyrosine supplementation on orthostatic hypotension in people with PD. - Secondary: To determine the effects of tyrosine supplementation in people with PD with autonomic insufficiency on HR, BP, and norepinephrine responses during acute exercise stress. Orthostatic hypotension and autonomic abnormalities are a common problem for individuals who suffer from PD, especially as it leads to lightheadedness and falling. For those affected, it can drastically reduce quality of life. It has been hypothesized that tyrosine may impact upon individuals suffering from PD. There is ample evidence in animal models that supports our theory; however there is no clinical evidence of the impact tyrosine supplementation may have in PD patients who suffer from orthostatic hypotension and blunted BP and HR responses. Positive findings that supplemental tyrosine increases BP and HR in people with PD during daily activities such as standing up from a chair and walking can lead to new therapies to improve Parkinsonian orthostatic hypotension. Hypothesis We will test the hypothesis that symptomatic individuals with PD on dopamine therapy who suffer from orthostatic hypotension and blunted HR and BP responses will improve after tyrosine supplementation.
The purpose of this study is to determine whether pramipexole and bromocriptine are effective in the treatment of non-motor symptoms in Parkinson's Disease.
The potential role of Small bowel bacterial overgrowth (SBBO) in weight loss occurring in patients with PD has not previously been examined. Our hypothesis is that SBBO is an important contributor to the development of weight loss in individuals with Parkinson's disease. The investigators propose to 1) examine the role of SBBO in weight loss occurring in patients with PD and 2) determine the response to its treatment with a poorly absorbed antibiotic. The investigators propose to perform a prospective, observational case-control study with an open-label therapeutic component. Cases will be defined as those PD patients who've experienced significant weight loss while Controls will be defined as those PD patients who have not experienced significant weight loss.
To study associate factor of Noctural Parkinson's Disease Symptoms and quality of life in Parkinson's disease patients and caregivers.
The purpose of this study is to explore the efficacy of the drug Amantadine for the treatment of freezing of gait in patients with Parkinson's Disease. The investigators hypothesize that amantadine is useful for management of freezing of gait in subjects with Parkinson's Disease.
The purpose of this study is to fulfil regulatory requirements for registration of a new chemical entity in China. Rasagiline is approved for the treatment of Parkinson's Disease (PD) in Europe and the US. Rasagiline is safe and well tolerated in healthy subjects, and the efficacy and safety has been demonstrated in placebo- and active comparator-controlled phase III studies.
The aim of this study is to compare two physical therapy training consisting of gait training that are distinguished by one being associated with tasks that require handling of the main executive functions, performed by individuals with Parkinson's Disease. The investigators hypothesis is that the experimental group (EG), which hold gait training with higher cognitive demands (dual-task condition), will make improvements in the parameters measured (functionality of gait and cognitive ability) to a greater extent compared to the control group (CG), which hold gait training without executive tasks (single-task condition).
The aim of this study is the development and implementation of a new protocol of a physical therapy training, based on a gait training associated with executive tasks, for treatment of individuals with Parkinson's Disease. The hypothesis is that this group of patients who will carry out training of this study protocol will show improvement in measured parameters (functionality of gait and cognitive ability), which allows this protocol to be improved and published as a proposal of physiotherapeutic treatment.
This randomized, controlled trial (RCT) evaluates the benefits of memory and problem solving training compared to supportive therapy in individuals with Parkinson's Disease with Mild Cognitive Impairment (MCI) and their support persons. Participants will be randomly assigned to receive memory and problem solving training or supportive therapy for 2-months. A 6-month follow up evaluation will establish if benefits remain over time. Impact of these therapies on thinking abilities, physical health, and patient and support person ratings of thinking skills, mood and quality of life will be evaluated. The memory and problem solving training is hypothesized to result in greater improvements and/or stability of function on neuropsychological tests of attention, working memory, learning, and memory skills compared to the supportive therapy condition. Both conditions are hypothesized to result in improved mood and quality of life ratings. Results from this study will determine whether memory and problem solving therapies and supportive therapy are easily used by and beneficial for individuals with Parkinson's Disease and Mild Cognitive Impairment. If positive benefit is observed, information from this study will be used to further optimize these therapies for larger trials designed to evaluate the value of the therapies for individuals with Parkinson's Disease and their support persons.
This project is investigating whether a one-year in-home exercise program will reduce the rate of falls and improve strength and quality of life in patients with Parkinson's disease.
