Filter by:The purpose of this study is to determine whether rasagiline is effective in the treatment of apathy in patients with Parkinson's disease.
The objective of this study is to establish the safety and tolerability of isradipine, sustained release preparation in patients with PD. This study is a logical continuation of the project that is being completed now and is conducted in preparation to NIH submission of the pivotal study on the efficacy of this agent for neuroprotection in PD. This study is conducted in parallel with Dr. Surmeier's work on further development of the preclinical data. The focus of his work now is to establishing the correlation between the dose that demonstrated neuroprotective effect in animal model and the dose used for clinical practice. Hypothesis 1: Patients with PD will be able to tolerate isradipine across the FDA recommended dose range. We expect 10% attrition due to hypotensive effect of the agent. Hypothesis 2: Patients with PD and concomitant stable hypertension will be able to tolerate isradipine provided that the dose of the concomitant antihypertensive agent is adjusted based on the blood pressure reading.
Sensory and motor cueing have been demonstrated as useful ambulation training techniques for Parkinson's disease (PD). This study is aimed to evaluate the effectiveness of treadmill training program with music cueing for mild to moderate PD patients.
Patients with Parkinson's disease (PD) are heavily inclined towards a sedentary lifestyle. This is caused by a combination of physical impairments and cognitive dysfunction. However, regular physical activity in PD is highly desirable, for two reasons. First, physical activity has positive generic effects in preventing complications such as cardiovascular diseases, type II diabetes mellitus, osteoporosis and certain cases of cancer. Secondly, physical activity has additional disease-specific merits in PD such as depression, sleep disturbances and constipation. These effects lead to raised quality of life. Furthermore, animal studies suggest that physical activity could slow down disease progression. Simply informing patients about the importance of physical activity is not enough to initiate and maintain an adequate level of physical activity. We propose to develop a physical activity promoting program for sedentary patients with PD in order to raise their level of daily physical activity. Objective: The first aim of the study is to investigate whether a physical activity promotion program will result in an increase in physical activity in sedentary patients with PD. The second aim is to demonstrate an increase in physical fitness and quality of life.
1. Briefly describe the purpose of this protocol: - The purpose of this study is to see how low dose vs. high dose of the study drug, carbidopa, effect movement in subjects with Parkinson's disease. The low dose of the study drug is 75 mg and the high dose is 450mg. 2. Briefly describe the procedures subjects will undergo: - Subjects will take part in 2 screening visits one week apart to determine eligibility. Subjects will be randomly chosen to start either high or low dose carbidopa and take it for 4 weeks. Subjects will be called 2, 4, and 6 or 7 days after this visit to ask how they are doing after starting this dose of study drug. The investigators will leave subjects a message if the investigators cannot reach them. If there are any problems, the investigators will schedule them to come to the clinic within the next 2 days. - Subjects will have an outpatient visit 2 weeks after screening and a hospital admission 2 weeks after that. At the hospital, subjects will stay for 3 days. They will have blood drawn and their Parkinson's disease assessed by a finger tapping exercise, timing their walking, and looking at their uncontrolled movements. - The subject will then receive the opposite dose of carbidopa for 4 weeks. Subjects will be called 2, 4, and 6 or 7 days after this visit to ask how they are doing after starting this dose of study drug. The investigators will leave them a message if we cannot reach them. If there are any problems, the investigators will schedule them to come to the clinic within the next 2 days. - The outpatient visit and hospital admission will repeat again. At the end of the second hospital admission, treatment on the study is over and subjects will go back to their original Parkinson's disease medications. The study will end with a follow up phone call or clinic visit 2 - 4 weeks after the final hospital admission. 3. If applicable, briefly describe survey/interview instruments used. - Subjects will fill out a daily diary that asks about their movement throughout the day for 3 days before they come to the Oregon Clinical and Translational Research Institute. 4. Briefly describe how the data will be analyzed to address the purpose of the protocol. - Finger tapping rates will be compared between high and low dose study drug use to see if one group has slower rates than the other.
This research study will evaluate functions of memory, thinking, behavior, and daily life activities and how these relate to the measurement of certain chemicals (acetylcholine and dopamine) in the brain using an imaging procedure called positron emission tomography (PET). You may know that in Alzheimer's dementia (dementia is a disease where persons become forgetful and confused), a reduction in the amount of acetylcholine, a "neurotransmitter" substance (a chemical messenger that nerve cells need to communicate with each other), may be responsible for some of the memory and behavioral changes. At the present time, the investigators have no clear information on the levels of acetylcholine in the brain of patients with Parkinson's disease who also have memory or behavioral changes.
This research study will evaluate functions of memory, thinking, eye movements and walking and how these relate to the measurement of certain chemicals (acetylcholine and dopamine) in the brain using an imaging procedure called positron emission tomography (PET). You may know that the brain chemical dopamine, a "neurotransmitter" substance (a chemical messenger that nerve cells need to communicate with each other), is important for the brain to control movements and that the brain chemical acetylcholine may have functions related to mental concentration and attention. At the present time, the investigators have no clear information how these two chemicals in the brain of patients with Parkinson's disease are related to the risk of falling.
The objective of the Post Marketing Surveillance Study is to investigate the use of the non-ergot dopamine agonist piribedil (trade name: CLARIUM) in mono- and combination therapy in patients with Morbus Parkinson. Neurologists in private practices in Germany should document the safety and course of the disease/change of parkinsonian symptoms during stabilisation on, or change over from other dopamine agonist treatment under routine conditions. Piribedil should be prescribed according to its marketing authorisation.
The aim of the non-interventional Post Marketing Study is to investigate the use of the non-ergot dopamine agonist piribedil (trade name: CLARIUM) in mono- and combination therapy in patients with Morbus Parkinson. Tolerability and course of the disease or change of parkinsonian symptoms during stabilisation on, or change over from other dopamine agonists will be documented under routine conditions. Piribedil should be prescribed according to its marketing authorisation by the responsible neurologist.
To investigate how levodopa and acupuncture affect fatigue and muscle function in people who suffer from Parkinson's disease. Subjects may choose to participate in levodopa or acupuncture part, or both. Study procedures include an exercise protocol, transcranial magnetic stimulation (a non-invasive type of brain stimulation that cause small muscle twitch), a blood draw, and personality surveys.
