Active clinical trials for "Parkinson Disease"

This study aims to characterize dynamic stability disorders in two conditions mainly affecting the elderly and with similar walking deficits: hydrocephalus at normal pressure and Parkinson's disease, to provide the most relevant monitoring criteria in usual care.

This is a non-drug study in patients with Parkinson's Disease (PD) and healthy volunteers to process and analyze their blood and optional cerebrospinal fluid (CSF) samples ex vivo, or outside of their body, to further develop researchers knowledge on LRRK2 biomarkers. Participants were enrolled either in Cohort A or in Cohort B. A blood sample was collected in each participant within a maximum of two study visits within 14 days, and an option to complete both visits on the same day.

Articulatory deficits are present in most speakers with dysarthria, which negatively impacts their speech intelligibility, yet little is known about the relationship between articulatory movement and speech intelligibility. This study will examine the relationship between articulation measures, both acoustic and kinematic, and their relationship to perceptual measures (i.e., speech intelligibility and articulation ratings) in 30 individuals with dysarthria secondary to Parkinson's disease and 30 neurologically healthy adults of the same age. The findings will have implications for behavioral management.

This study is to evaluate the human tolerance and pharmacokinetics of LY03003.

Rationale: Parkinson's disease patients with deep brain stimulation electrodes represent a unique opportunity to study the influence of basal ganglia on neurocognitive function. Intervention: Patients' deep brain stimulators will be turned off or on and the frequency will be changed to either theta or gamma. Objectives: To identify differences in higher cognitive functions with stimulation "on" and "off" and theta versus gamma frequency stimulation. Study population: 12 patients who had previously undergone bilateral STN deep brain stimulation implantation. Study methodology: Patients will undergo four sessions of neuropsychological testing (RNGT, verbal fluency, D-KEFS CWIT) at baseline, no stimulation, theta stimulation and gamma stimulation, in random order over one day. Study outcomes: Test results of RNGT, verbal fluency, D-KEFS CWIT. Follow-up: none Statistics: Test results will be analyzed using within-subjects statistical tests.

Transcranial magnetic stimulation (TMS) is a procedure that has been shown to improve pain in chronic sufferers. It is a well-tolerated procedure that can be performed on an outpatient basis. It uses a plastic covered coil that sends a magnetic pulse through the skull into the brain and by targeting particular areas in the brain it can be used to help modulate the perception of pain. The study intends to use this technique to treat such a disabling symptom in patients who suffer from Parkinson's Disease (PD). Initially the aim is to study this technique in 48 patients who are suffering from pain and have PD. These patients would require an EEG before and after the stimulation. The stimulation would be performed over ten sessions and the patients would be assessed by a clinician using well recognized clinical tools. It is anticipated that there will be a meaningful improvement in pain. It is also anticipated that TMS is a safe technique to use in patients with PD. The study will be used to help plan a future study that compares TMS with sham technique to prove whether TMS could be an option in the treatment of such a disabling condition.

The purpose of this research study is to establish if a novel high-speed yoga program which incorporates visual cues can make a positive change in the participant's ability to make decisions and move as measured by several cognitive, balance and functional tests. It has been shown that yoga can improve balance and movement in those diagnosed with Parkinson's disease.

Parkinson's disease psychosis encompasses a range of symptoms, including minor phenomena, frank hallucinations, and delusions. Minor phenomena include passage hallucinations (fleeting sense of a person, animal or object passing in the periphery), presence hallucinations (feeling of nearby presence), and illusions (misrepresentation of external stimuli). Some forms of PD psychosis may be progressive. The primary objective of this study is to: 1) To determine the cumulative probability of developing hallucinations or delusions over time in individuals with PD minor phenomena followed for 36 months.

The goal of this project is to identify objective, sensitive, and convenient measures for assessing early signs of Parkinson's disease in an at-risk population at home. We will do so by using a wireless sensor and analyzing the radio signals that bounce off patients' bodies, while patients go about their normal life without needing to wear sensors, answer questionnaires, or actively perform any tests.

The study uses magnetic resonance imaging (MRI) to better understand changes in the brain underlying motor symptoms affecting upper and lower limbs in Parkinson's disease.
