This study will be looking at the effects that instability resistance training and aerobic training, individually, have on the improvement of various motor and cognitive impairments present in individuals with Parkinson' disease. There will be 25-30 participants in this study (all of whom have Parkinson's disease). Once passing the eligibility criteria, participants will complete as series of baseline/pre-tests and then be randomly assigned to either the aerobic training group or the instability training group, where they will participate in every training session that occurs in the next 8 consecutive weeks. There will be 3 training sessions a week occurring on non-consecutive days (ex. Monday, Wednesday, Friday) for both training groups (3 aerobic training sessions, 3 instability resistance training sessions). Once the 8 week training intervention has been completed, a series of post-tests will occur exactly once week after (same tests used as in the pre-tests)
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of multiple oral doses of DNL201 in subjects with Parkinson's disease.
Over the past decade, experimental data has suggested a complex and bidirectional interaction between the gastrointestinal (GI) tract and the central nervous system (CNS), the so-called "Gut- Brain axis." . Changes in the gut microbiota composition may cause alterations in the gut barrier function and intestinal permeability, affecting not only GI epithelial cells and immune system, but also the ENS including both neurons and glial cells . The bidirectional brain-gut-microbiota axis interactions modulate pro- and anti-inflammatory responses. It has been suggested that the gut microbiota changes associated with intestinal inflammation may contribute to the initiation of α-syn misfolding. There is a growing number of evidence confirming that the gut microbiota alterations precede or occur during the course of PD. Importantly, some genetic risk factors may play a crucial role in the interactions between the brain-gut-microbiota axis with respect to gut inflammation. It has been also shown that the methylation status in the SNCA promoter region may affect α-syn expression and the risk for PD. Therefore, a potential role of the gut microbiota as an epigenetic factor influencing DNA methylation may be speculated. Moreover, genetic variant of the component of innate immune system - TREM2 (Triggering Receptor Expressed on Myeloid cells) has been reported to be associated with a higher risk for PD. The ε4 allele of apolipoprotein E (ApoE) has been shown to increase the risk for dementia in synucleinopathies such as PD. Potentially, ApoE genotype, by influencing bile acid secretion, could affect the composition of the gut microbiota to favor the development of organisms triggering misfolding. Moreover, three single nucleotide polymorphisms in CARD15 gene, known to be associated with Crohn's disease, have been also shown to be over-expressed in PD patients, supporting the observation that GI inflammation contributes to the pathogenesis of PD.
The purpose of this study is to evaluate the microbiome of medicated and non-medicated subjects diagnosed with Parkinson's disease. Where available, in comparison to the microbiome of a healthy spouse or 1st degree relative.
The primary objective of this study is to determine the recommended dose and evaluate the effect of KW-6356 on motor symptoms in Parkinson's disease and the primary endpoint is the change from baseline in Movement disorder society-unified Parkinson's disease rating scale(MDS-UPDRS) partIII score between KW-6356 and placebo in patients with Parkinson's disease on treatment with Levodopa-containing preparations as an adjunctive therapy.
The complex pathological cascades leading to both Alzheimer's disease (AD) and Parkinson's disease (PD) involve, at various points, inflammation. Since inflammation is a treatable symptom, understanding how and when it impacts the brain, and where specifically in the brain, would offer important guidance in the development of new treatments, sorely needed in both diseases. Microglia play an important anti-inflammatory role, and produce a substance, mitochondrial translocator protein (TSPO), whose presence can be used as a marker of regional inflammation. GE180 is a newly developed PET ligand which binds to TSPO and hence can be used in imaging studies to analyze regional inflammation in living patients. In prior studies it has shown regional specificity in multiple sclerosis and brain injury. In the current study, the investigators will be using GE180 to analyze regional and global inflammation in the brains of patients with AD and PD at two time points. The results of the current study will provide enriched understanding of inflammation in these conditions, and potentially provide preliminary data to inform design of future interventional trials.
This study addresses several issues related to the clinical management of speech and voice disorders associated with Parkinson's disease. Two behavioral treatment programs, Lee Silverman Voice Treatment and SpeechVive, are assessed in their ability to improve communication in persons with Parkinson's disease.
This study will assess the feasibility of using specific criteria to standardize the referral of individuals with Parkinson disease to a group of medical providers known as palliative care specialists. Palliative care specialists provide supportive care to individuals living with serious illnesses. The specialty focuses on providing relief from the symptoms and stress of serious illness.
The purpose of this study is to assess the feasibility, in regards to acceptability and implementation, of the Pre-Active PD intervention for increased high intensity goal-directed aerobic exercise engagement in people with early-stage Parkinson's disease (Hoehn and Yahr stage I & II). In addition, the study aims to explore the effect estimates of the Pre-Active PD intervention on self-efficacy, motivation, stage of behavior change, and physical activity levels in people with early stage Parkinson's disease.
There is currently no consensus on the adequate concomitant treatment to apomorphine pump in Parkinson's disease (PD). In practice, some centers withdraw all dopaminergic agonists when initiating apomorphine pump therapy, whereas others combine the two. To date, there has been no study led to determine the best strategy for efficiently treating motor and nonmotor symptoms, as well as improving patients' quality of life (QoL). This preliminary study, entitled AGAPO, aims at identifying significant differences in patients' evolution (nonmotor symptoms and quality of life), over a course of 6 months, depending on the two strategies adopted in French centers (apomorphine pump with or without dopaminergic agonists), through the Non Motor Symptoms Scale (NMSS, Chaudhuri et al, 2017).
