Filter by:The clinical management of Parkinson's disease (PD) is frequently challenged by the occurrence of motor disorders and complications, such as freezing of gait, fluctuations and the ON-OFF phenomenon, primarily manifesting at home. Therapeutic decisions are usually based on periodic neurological examinations and patients' anamnestic experience collected in an outpatient setting, thus limited by several issues, including "recall bias" and subjective, semi-quantitative and operator-dependent evaluations in non-ecological settings. In the last two decades, new wearable technologies, consisting of "wireless" sensors (e.g., inertial, electromyography), have been widely applied to quantitatively assess movements in physiological and pathological conditions, even for prolonged periods in free-living settings (i.e., long-term monitoring). The aim of this study is to evaluate motor symptoms in patients with PD, such as bradykinesia, tremor, gait disturbances and balance disorders, objectively and quantitatively through the application of wearable sensors in intra- and extra hospital settings, also during common activities of daily living, in order to obtain ecological data possibly useful in the therapeutic management of the disease.
To characterize using a participant centered decentralized (at home) study featuring wearable technology and telemedicine to study disease change over time in patients with PD caused by the G2019S mutation in the LRRK2 gene and to identify a clinical endpoint(s) for disease modifying experimental therapy trials.
The cardinal motor features of Parkinson's disease (PD) include bradykinesia, rest tremor, and rigidity. Though non-motor features have been recognized for centuries, only recently has the prevalence and impact of non-motor symptoms become the focus of intense study. Disturbances of sleep are among the most common non-motor manifestations of PD; approximately two-thirds of PD patients experience sleep dysfunction of some kind. Given that sleep contributes to the regulation of many physiological processes, sleep disturbance has a significant impact on quality of life in PD, and places high strain on caregivers. Though numerous symptomatic therapies exist, the treatment of sleep disorders in PD is limited by a lack of adequately powered, randomized studies providing high quality evidence. Although deep brain stimulation (DBS) is primarily used to treat PD motor symptoms and reduce the need for dopaminergic medications, several studies have shown that DBS provides benefit for non-motor symptoms, including sleep disturbance. Few studies have used an objective measure to assess the impact of DBS on sleep in PD, and none have done so by studying sleep in the home environment. Existing studies have largely been limited to a single night of sleep recording in a sleep lab. Furthermore, no studies have assessed sleep both on and off medication, before and after DBS implantation. This study will enroll patients undergoing evaluation for DBS implantation. Sleep will be assessed before DBS implantation, both while patients continue their usual medication regimen and while withholding medications. After DBS implantation and programming, sleep will again be assessed with stimulation on, both while continuing medications and subsequently while withholding medications.
In this study, researchers will learn more about a study drug called BIIB122 in participants with early-stage Parkinson's disease (PD). In this study: - Participants will take 225 milligrams (mg) of BIIB122 or a placebo as tablets by mouth. A placebo looks like the study drug but has no real medicine in it. - Participants will take BIIB122 or placebo 1 time a day for up to a minimum of 48 weeks and a maximum of 144 weeks. - Certain medications for PD will be allowed at enrollment for a subset of participants. - Participants will have to visit at 2-week intervals between baseline and week 12 and at 4-week intervals between week 12 and week 48 and at 12 week intervals between week 48 and week 144. The main question researchers are trying to answer is if taking BIIB122 slows the worsening of symptoms more than placebo in the early stages of PD. To help answer this question, researchers will use a questionnaire called the Movement Disorder Society-Unified Parkinson's Disease Rating Scale, also known as the MDS-UPDRS. Researchers will use the MDS-UPDRS to learn about participant PD symptoms and how they affect their daily life. Researchers will also learn more about the safety of BIIB122.
Parkinson's disease affects all the nerve cells in the body, including the ones in the gut. The gut contains its own nervous system, the enteric nervous system, and can be thought of as a "second brain". This second brain can reflect what is going on in the actual brain. This study is being done to look for biomarkers, or early indicators of developing Parkinson's disease, in the microbiome and in the gut tissue taken during routine screening colonoscopy. People aged 45 and over who are due for their routine screening colonoscopy are eligible to participate.
NR-SAFE is a double-blinded randomized safety study aiming to determine the safety and tolerability of nicotinamide riboside (NR) at a daily dose of 3000mg, in individuals with Parkinson's disease (PD). The investigators recently reported the results of the NADPARK study (ClinicalTrials.gov: NCT03816020), a phase I randomized, double-blinded trial, assessing the tolerability, cerebral bioavailability and molecular effects of NR therapy, 1000mg daily, in PD. The NADPARK study showed that NR 1000mg daily was well tolerated and led to a significant, but variable, increase in cerebral NAD levels (measured by 31phosphorous magnetic resonance spectroscopy, 31P-MRS) and related metabolites in the cerebrospinal fluid (CSF). NR recipients showing increased brain NAD levels exhibited altered cerebral metabolism, measured by 18fluoro-deoxyglucose positron emission tomography (FDG-PET), and this was associated with mild clinical improvement. The results of the NADPARK trial nominate NR as a potential neuroprotective therapy for PD, warranting further investigation in larger trials. It is plausible that any beneficial effects of NR in PD may be dose-dependent and more pronounced at higher doses. NR doses of up to 2000mg daily have been tested in healthy humans with no signs of toxicity. However, the safety and tolerability of even higher doses is untested. To enable clinical studies assessing higher doses, the investigators will assess the safety and tolerability of an oral dose of 3000 mg NR daily. NR-SAFE will recruit 20 participants with PD and randomize them 1:1 to either NR 3000mg daily or placebo for a total duration of 4 weeks.
This is an open-label, sequential cohorts, flexible dose study to evaluate the tolerability, safety and pharmacokinetics of iloperidone in elderly patients with Parkinson's disease psychosis (PDP).
The objective of this study is to identify key indicators in the follow-up of subjects with different pathologies related to both the person's environment, as well as the perception of their health and general quality of life and related to their disease. To this end, a cross-sectional observational study of qualitative data collection through questionnaires, mostly validated, has been proposed to try to identify these indicators. Based on these questionnaires, the specific objectives of this study are as follows: - Unify questionnaires - Assess data quality - Identify key indicators, through a factor analysis - Design a second reduced version of the questionnaires collecting the key indicators and eliminating those items that are exclusive to each other. In order to identify the key indicators, it will be necessary to measure at least 30 subjects from each pathological group, as well as a cohort of at least 100 subjects without pathologies in order to validate and contrast the results. The subjects will be recruited through the own databases of participants in previous trials of the Institute of Biomechanics of Valencia, who have given written consent to be contacted in order to request their participation in any other study where their profile may fit. They will also be recruited and contacted through the collaborating associations (Parkinson Valencia Association, Valencian Diabetes Association, Consorci Hospital General Universitari de València, Arnau de Vilanova Valencia Hospital). The surveys will be included in an online platform specialized in the realization of questionnaires. This data will be exported for further storage, management and analysis. All information will be anonymized for processing and analysis, and may be used under the terms and conditions dictated by the current legal framework. To participate in the study, participants must accept the terms and conditions included in the first page of the survey embedded in the online platform, where the aspects related to the study methodology and the use of them data are exposed. The statistical analysis will treat the data provided by the variables and how they are related to each other, testing differences according to the characteristics of the patient and clinical indicators. For that, non-parametric techniques such as the χ² test, the Kruskal-Wallis test and cluster analysis will be used.
Introduction: Home rehabilitation is a form of care that is part of most health systems. Patients with Parkinson's disease can be referred to these Home Rehabilitation Services given the characteristics of the pathology they suffer. Objective: know and analyse the clinical-epidemiological characteristics of patients with Parkinson's disease referred to a Home Rehabilitation Service belonging to health Area V of Gijón, Asturias, Spain. Study Design: This project proposes an observational and retrospective study. Study population: The subjects that will be part of this study will be men and women with Parkinson's disease who have been referred to the Home Rehabilitation Service from 2015 to 2021.
This study is a waitlisted randomized controlled trial. We aim to assess the level of compliance for those learning the intervention and to evaluate the impact of the practice on neuropsychological and somatic outcomes using validated scales. Enrollment into the study will be ongoing until we are able to get a sufficient sample size as described in the "Statistical Consideration" section. Upon enrollment and randomization, surveys will be administered to both the intervention and control groups at four time-points: baseline, T2, T3, and T4, each of which are 6 weeks apart. Compliance data will be collected weekly for 12 weeks for both groups.
