Filter by:Background: - In deep brain stimulation (DBS), a device called a neurostimulator is placed in the chest. It is attached to wires in parts of the brain that affect movement. DBS might help people with movement disorders like Parkinson s disease (PD), dystonia, and essential tremor (ET). Objective: - To provide DBS treatment to people with some movement disorders. Eligibility: - Adults 18 years and older with PD, ET, or certain forms of dystonia. Design: - Participants will be screened with medical history and physical exam. They will have blood and urine tests and: - MRI brain scan. The participant will lie on a table that slides in and out of a metal cylinder with a magnetic field. They will be in the scanner about 60 minutes. They will get earplugs for the loud noises. During part of the MRI, a needle will guide a thin plastic tube into an arm vein and a dye will be injected. - Electrocardiogram. Metal disks or sticky pads will be placed on the chest, arms, and legs. They record heart activity. - Chest X-ray. - Tests of memory, attention, concentration, thinking, and movement. - Eligible participants will have DBS surgery. The surgery and hospital care afterward are NOT part of this protocol. - Study doctors will see participants 3 4 weeks after surgery to turn on the neurostimulator. - Participants will return every month for 3 months, then every 3 months during the first year, and every 6 months during the second year. Each time, participants will be examined and answer questions. DBS placement will be evaluated with MRI. The neurostimulator will be programmed. At two visits, participants will have tests of movements, thinking, and memory.
This study is evaluating the use of two painless, non-invasive technologies in the assessment of muscle health over time in both healthy volunteers and patients who have diseases that affect the nervous system.
The purpose of this study is to record electrical brain activity during DBS surgery and after DBS surgery using the Medtronic Activa PC+S deep brain stimulation (DBS) system, a modified DBS pulse generator. The goal of the study is to investigate if the electrical brain activity can help customize DBS therapy.
Parkinson disease (PD), multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) are neurodegenerative disorders. PD and MSA are alpha-synucleinopathies, which are characterized by the abnormal accumulation of alpha-synuclein, while tau protein accumulates in PSP. The development of biological markers for the diagnosis and prognosis in PD, MSA and PSP remains an unmet need. Such biological markers are crucial for future disease-modification and neuroprotection trials. Alpha-synuclein has a high potential for biomarker development since it constitutes the pathological hallmark feature in PD and MSA. The oligomeric alpha-synuclein seems to be particularly involved in abnormal protein aggregation in alpha-synucleinopathies. The main objective is to compare oligomeric alpha-synuclein CSF levels between PD, MSA and PSP patients. PD and MSA patients will receive Cerebrospinal Fluid (CSF) and blood sampling at two study visits (baseline and after 12 months). Major secondary objectives are (i) to assess potential associations between the biomarker and clinical measures of disease severity and progression in MSA and PSP, and (ii) to assess the variation of the biomarker and its correlation to disease severity and progression in PD, MSA and PSP.
The purpose of this study is to investigate the impact of a specifically designed leg brace on walking endurance in individuals with Parkinson's disease.
It has been hypothesized, based on epidemiological observations, that Helicobacter pylori (HP) infection may play a role in the pathogenesis of Parkinson's Disease (PD). Previous studies have also shown that HP eradication therapy may result in improvements in levodopa pharmacokinetics and motor fluctuations. This study aims to examine the effects of HP eradication, using a double-blind randomized placebo-controlled trial design in a relatively large cohort of patients. Outcomes of interest include motor function, gastrointestinal symptoms and health-related quality of life. The investigators hypothesize that HP eradication will lead to improvements in motor function. The primary outcome of interest is the "ON"-medication Unified PD Rating Scale (UPDRS) Part III score at 3 months. Secondary outcomes include Purdue Pegboard Score, Timed Test of Gait, Dyskinesia and Bradykinesia scores measured by Parkinson's Kinetigraph (PKG), Leeds Dyspepsia Questionnaire (LDQ), Parkinson's Disease Questionnaire (PDQ-39), UPDRS Part I, Part II and Part IV; and Montreal Cognitive Assessment (MOCA).
This research will help us to understand whether transcranial direct current stimulation (tDCS) can safely improve recovery of speech and language abilities, gait , and mood in people with Parkinson's disease and related disorders. Some of the disorders that will be studied to understand if tDCS can be useful include Parkinson's Disease, Multi-System Atrophy (MSA) and progressive supranuclear palsy (PSP).
This exploratory trial will fulfill a medical data gap for the dopamine-agonist rotigotine, as so far no data on elderly population is available. Primary objective: To assess efficacy and safety of rotigotine in patients with late onset Parkinson's Disease (PD), starting at age 70 or later, on motor symptoms. Secondary objective: To assess efficacy and safety of rotigotine in patients with late onset Parkinson's Disease (PD), starting at age 70 or later, on selected non motor symptoms : sleep quality; depression; cognitive function. Subjects ≥70 years, with diagnosis of Parkinson's Disease (PD) based on the presence of at least two of three cardinal features (bradykinesia, resting tremor, rigidity), within 12 months since diagnosis and no longer than 12 months from onset to diagnosis, and for whom the caring physician is uncertain on whether or not to start treatment. Outcome Measurement: Percentage of Responders to treatment in motor (part III) and Activities of daily living (ADL) (part II) components of Unified Parkinson's Disease Rating Scale (UPDRS) at visit 4 and 6; Percentage of Responders to treatment in sleep quality in relation to Parkinson's Disease Sleep Scale (PDSS)-2 at visit 4 and 6; Responders to treatment in mood in relation to Geriatric Depression Scale (GDS) at visit 4 and 6. Exploratory, randomized, double blind, placebo-controlled study: 80 patients with late onset Parkinson's Disease (PD) are randomized in 2 parallel groups, ratio 1:1. One group will be treated with rotigotine and one group will be treated with placebo, for 12 weeks after titration.
Decreased muscle strength has been reported to be a factor contributing to increased incidences of falling in the elderly patients causing fractures, joint dislocations, severe soft tissue lesions and head trauma. Parkinson's Disease (PD) patients often complain of weakness and it has been reported that they have reduced muscle strength, decreased rate of force development, impaired ability to maintain constant force, and increased muscle coactivation during balance perturbation tasks. The specific cause of this weakness is not known, and in this study the investigators have analyzed and measured isokinetic muscle strength in PD patients to clarify this issue. The investigators have compared the data obtained with those of age-matched controls.
The purpose of this study is to assess the pharmacokinetics (PK) of BIA 9-1067 in patients with moderate chronic hepatic impairment and in matched healthy subjects.
