Filter by:This is a 44-week, randomized, placebo-controlled, double-blind, single-center, phase 1 clinical trial consisting of a dose-escalation Part A study in healthy participants, followed by a Part B in participants with Parkinson's disease with a selected doses from Part A.
The objective of this study is to compare the effectiveness of a personalized patient education program to the current hospital education and evaluate its impact using patient satisfaction scores. The investigators hypothesize that a personalized patient education intervention will increase patient's understanding of their diagnosis and satisfaction with the care as reflected in the survey results.
This observational and experimental study seeks to establish a Smart Device System (SDS) to monitor high-resolution handtremor-based data using Smartphones, SmartWatches and Tablets. By doing this, movement data will be analyzed in depth with advanced statistical and Deep-Learning algorithms to identify new clinical phenotypical characteristics Parkinson's Disease and Essential Tremor.
The purpose of this study is to examine the short term effects (12 Weeks) of Lactobacillus plantarum PS128 (PS128) on Parkinson's disease (PD) symptoms.
BACKGROUND: Non-Motor Symptoms (NMS) are frequent in patients with Idiopathic Parkinson's Disease (IPD). Clinical expressions, postulated pathophysiological mechanisms and responsiveness to antiparkinson medication represent differences between IPD and secondary Parkinsonism (SP). OBJECTIVES: To evaluate NMS expressions in IPD, SP and a control group. METHODS: Diagnosis of SP was supported by comorbidity, radiological findings, type of onset, onset rate and progression, exposures for neuroleptics, and responsiveness to pharmacological antiparkinson therapy. The participants were consecutively recruited at two outdoor patient clinics. The Well-Being Map™ for evaluation. These were completed by the participants at one point before visit. The controls consisted of non-Parkinsonian individuals, matched by age and gender.
Parkinson's disease (PD) is a progressive neurological disorder that is increasingly common with age, with the incidence rising from approximately 4 people per 10,000 in their forties to 2 in 100 over the age of eighty. Our understanding of the causes of PD has rapidly developed in the past two decades, but this has not yet translated into any clinically established neuroprotective treatment that slows disease progression. There is a growing consensus that the failure of previous efforts is mainly due to the causative diversity of PD i.e. that PD may have many different causes. For example, it is known that variants in mitochondrial (cellular power house) genes can cause specific forms of PD and this may be relevant to other forms of PD. The aim of this study is to attempt to group PD patients based on markers of biochemical dysfunction (e.g. into groups of patients that do and those who do not have evidence of mitochondrial dysfunction) to aid in the development of new candidate neuro-protective compounds. The investigators hope by grouping people with Parkinson's into those with and without impaired mitochondrial function the investigators will be better able to develop more targeted treatments aimed at protecting further loss of brain cells that occurs in Parkinson's disease. To achieve this the investigators will study people, in two study sites in London, with both genetic forms of PD and those with idiopathic PD (i.e. those where there is not a known genetic variant causing PD), as well as a healthy control group. All groups will undergo standardised clinical assessment to collect information on several aspects of their condition (e.g. disease severity, memory problems and sleep problems). Participants will be asked to provide blood, urine and optionally cerebrospinal fluid & skin samples from which various biochemical assays and genetic analysis will be performed in attempt to group participants based on the results of these tests. The study is funded for 3 years with participants being asked to attend for up to 3 study visits each over this time period.
This study occurs during five visits that are already scheduled as part of "Biomarkers to Guide Directional DBS for Parkinson's Disease" (ClinicalTrials.gov Identifier: NCT03353688). If participants have dystonia associated with Parkinson's disease, the investigators will consent and administer one additional rating scale (Burke-Fahn-Marsden Dystonia Rating Scale) to assess the severity of dystonia.
The aims of this study are: 18F-THK5351 PET(Positron Emission Tomography) can defect the tau burden in PSP(Progressive Supranuclear Palsy) and CBS (Corticobasal syndrome)correlating with the known NFT(neurofibrillary tangles) topology of those diseases, 18F-THK5351 PET will differentiate subjects with suspected tauopathy due to PSP and CBS from subjects with suspected synucleinopathy due to idiopathic PD(Parkinson's disease). The distribution of PHF(paired helical filament) tau burden will correlate with specific motor and cognitive features of PSP and CBS; and regional PHF tau burden will be associated with cortical thinning. Together, these efforts will establish the potential for developing 18F-THK5351 PET imaging as a biomarker and diagnostic tool for the parkinsonian tauopathies.
This study evaluates the effect of the need to void on parkinsonian gait
The aim of this study is to determine whether a significant reduction in the total level of alpha-synuclein and significant increase in the oligomeric form of alpha-synuclein and therefore the ratio oligomeric:total alpha-synuclein occurs in patients with Parkinson disease compared to patients with drug-induced parkinsonian syndrome.
