Filter by:The goal of this clinical trial is to learn about the role of noradrenergic system in the non-motor symptoms of Parkinson's disease. The main objectives it aims to answer are: 1. To explore the association between orthostatic hypertension which is low blood pressure that occurs after going from lying to standing, and several neuropsychiatric and neurocognitive nonmotor features of Parkinson's disease (PD), such as feeling tired or disinterested and depression. 2. To explore the association between central noradrenergic dysfunction, orthostatic hypertension, and nonmotor symptoms of PD by measuring hormonal response to head up tilt-table testing before and after administration of yohimbine. 3. To explore the association between central noradrenergic dysfunction, orthostatic hypertension, and nonmotor symptoms of PD by measuring participants pupils before and after administration of yohimbine Participants will be asked to come onsite for two study visits. Visit one will consist of: - Discussing and signing the Informed Consent Form - Discussing Medical History and Current Medications - Collecting Blood samples - Measuring heart rate and blood pressure - Mental health screening and neurocognitive questionnaires - Pupil test - Test to feel vibrations Visit two will consist of : - Mental Health questionnaire - IV Placement - Blood Draws - Administration of Yohimbine hydrochloride - Head up tilt table - Measuring heart rate and blood pressure - Answering questions about anxiety, mood, and fatigue using a scale - Pupil tests Visit three will be a follow-up call from the Nurse Coordinator to discuss any adverse events.
The purpose of this study is to evaluate the effects of multiple therapeutic and supratherapeutic doses of KW-6356 on the QT interval corrected for heart rate in Japanese healthy adults.
Parkinson's disease is a progressive disorders characterized by motor and non-motor symptoms. Actual medical treatments are symptomatic and have little efficacy on late stage axial motor symptoms. Non-pharmacological approaches are therefore essential from the disease onset. Beside physiotherapy, to practice a regular adapted physical activity is crucial. To implement such a practice in everyday life implies to change habits. Patient Education programs are useful tools to help changing behaviors. The study evaluate the effect of a program aiming to promote adapted physical activity in early stage Parkinson's disease by comparing patients receiving the program and patients on a waiting list. The hypothesis that the program will increase the one-week mean daily moderate to intense physical activity as measured with an actimeter.
The broad goal of this research project is to improve the prediction of falls in patients with Parkinson's disease (PD) through a comprehensive multidisciplinary approach that includes longitudinal measurements of walking, cognitive and functional performances. PD is a life-changing disorders affecting one million Americans, with more than 60,000 new cases reported every year. Within 3 years of diagnosis, more than 85% of people with clinically probable PD develop gait problems, which in turn lead to falls resulting in serious injury and reduced quality of life. There is a pressing need to identify fall risk factors before the occurrence of the first fall, and to better understand behavioral and cognitive changes leading to falls in PD patients.
Single center, open-label, intra-individual dose-escalation study in subjects with mild/moderate Parkinson's Disease
Obstructive sleep apnea (OSA), which causes abnormal pauses in breathing during sleep, is common in patients with vascular cognitive impairment (VCI) and Alzheimer's disease (AD), and exacerbates the cognitive deficits seen in these conditions. OSA is typically treated with continuous positive airway pressure (CPAP), which has been shown to improve cognition in VCI and slow cognitive decline in AD. Despite the need to identify OSA in patients with VCI/AD, these patients often do not undergo testing for OSA. One major barrier is that in-laboratory polysomnography (iPSG), the current standard for diagnosing OSA, is inconvenient for patients with VCI/AD who may be reliant on others for care or require familiar sleep environments. A convenient and cheaper alternative to iPSG is home sleep apnea testing (HSAT), which has been validated against iPSG to diagnose OSA and has proven feasible for use in VCI/AD. Our primary objective is to determine whether the use of HSAT is superior to iPSG in terms of the proportion of patients who complete sleep testing by 6 months post-randomization. We will also investigate cost-effectiveness, patient satisfaction, proportion of patients treated with CPAP, changes in cognition, mood, sleep-related and functional outcomes between HSAT and iPSG at 6 months.
It is hoped that TAK-071 will help people with Parkinson's disease to walk with better balance. The main aim of the study is to check if there is a difference in how participants walk after treatment with TAK-071. Another aim is to see if it improves how participants think and remember. At the first visit, the study doctor will check who can take part. Participants who can take part will be picked for 1 of 2 groups by chance. Both groups will have 2 treatments but in a different order. The treatments are TAK-071 tablets or placebo. In this study, a placebo will look like the TAK-071 but will not have any medicine in it. One group will take TAK-071 for 6 weeks, have at least a 3-week break, then take a placebo for 6 weeks. The other group will take a placebo for 6 weeks, have at least a 3-week break, then take TAK-071 for 6 weeks. The participants will not know the order of their 2 treatments, nor will their study doctors. This is to help make sure the results are more reliable. The participants will visit the clinic at the beginning and end of each treatment for a check-up. 14 days after the 2nd treatment, clinic staff will telephone the participants for a final check-up.
The aim of this crossover study is to investigate the efficacy of non-invasive brain stimulation (transcranial pulse stimulation; TPS) in adults with Parkinson Disease (PD). Participants will receive 6 sessions of TPS and Sham-TPS, respectively, in random order. Motor manifestations of PD and manual dexterity will be the primary outcome measures. Outcomes will be assessed immediately post-treatment.
Prospective monocentric randomized controlled open-label proof-of-concept study in cross-over of two 1-month periods and a long-term follow-up period not to exceed September 30, 2023, with 2 groups: Intracerebroventricular A-dopamine versus optimized oral medical treatment in parkinsonian patients at the stage of severe motor complications (fluctuations and dyskinesias) related to oral L-dopa. In this study it will be expected to: 1) a higher benefit on motor symptoms 2) without tachyphylaxis, 3) a good ergonomic of the intra-abdominal pump refilled with A-dopamine every two weeks as compared with the numerous daily L-dopa doses and 4) a good safety profile of this classical neurosurgical procedure.
The purpose of this study is to obtain clinical outcome data on safety and effectiveness of the directSTIM DBS system when used on-label, according to the instructions for use. All participants will undergo bilateral implant in the subthalamic nucleus (STN) and data collected in common practice will be recorded during six months post-implant and analyzed.
