NCT05008094
Parkinson's disease (PD) is the second most common neurodegenerative disease, which affects 2-3% of the general population above 65 years. There are significant differences in incidence depending on geographical location, race, and ethnicity. The exact cause of the disease is still unknown, but the role of genetic and environmental factors has already been established. Certain genetic forms of the disease make up for a small percentage, so it is thought that environmental factors have a more significant impact on the development of the disease. The incidence of PD is higher in people exposed to significant quantities of pesticides and traumatic brain injury, while there is a smaller incidence in smokers and people consuming more significant quantities of caffeine. The project will finish in four years, with the first 20 months dedicated to the first phase (genetic-epidemiological research), and the entirety of the 48 months for the second phase of the project (prospective clinical research). The main goal of the first phase of the project is to determine which genetic mutations are the ones most represented in the Croatian population afflicted with the familial form of PD. In the second phase the main goal is to determine the influence of genetic factors and microbiological factors on the disease's progression as well as on the treatment outcomes. Specific goals of this part of the project are to determine how many patients in the general population of PD patients present with a genetic disorder and which genes have a role in that disorder, as well as determine the composition of intestinal and oral microbiota both in the patient test group and the healthy control group. Furthermore, specific goals are to evaluate the effects of standard PD treatment on the composition of microbiota, neurodegeneration progression and the activity of neuroinflammation in the central nervous system (CNS) and to examine whether there is a link between the physiological and the pathophysiological function of microbiota, using markers of disease progression and glial activity. Last specific goal is to analyze potential pathological conformation protein forms that could be used as a biomarker in early stages of the disease and a biomarker of disease progression. The first phase of the study will provide the first epidemiologic data on the familial form of PD, as well as the mutations most represented in patients with PD in Croatia. Additionally, the prospective clinical study will contribute to enlightening the intertwined effects of genetic and environmental factors in the emergence and progression of the disease, as well as their effect on treatment outcome. Intestinal and oral microbiota composition analysis will determine whether there is a difference between PD and the healthy population while using the short-chain fatty acid profile will determine the metabolic differences between the two groups. Analyzing the markers of CNS homeostasis, inflammation, and neuroglial function will determine the progression of the disease and also correlate them to genetic factors as well as the microbiota function and composition. Analyzing the pathological conformation forms of alpha-synuclein could lead to the discovery of novel biomarkers in the early stages of the disease, as well as to follow the progression of the disease
NCT02783014
This study investigates the central mechanisms of Overactive Bladder (OAB) in Patients with Parkinson's Disease (PD). The plan is to enroll 10 adults with Parkinson's disease and Overactive bladder (PD + OAB) and 10 adults with Parkinson's disease only (PD). Both groups will undergo fMRI (functional MRI).
NCT05003206
Deep brain stimulation (DBS) is recognized as the most safe and effective neurosurgical method for the treatment of advanced Parkinson's disease. However, the mechanism of relieving motor and non-motor symptoms of Parkinson's disease has not been fully clarified, and the prognosis is significantly different. This study is based on multimodal MRI technique to clarify the mechanism of DBS in relieving motor and non-motor symptoms of Parkinson's disease, and to explore imaging indicators that can predict prognosis, so as to guide the individual and accurate treatment of Parkinson's disease (PD).
NCT04997213
The aim of this study was to evaluate the effectiveness of static posturography-assisted biofeedback exercises in PD-related balance disorder.
NCT04434898
The hypothesis is that the differential extent of microstructural damages in the affected brain regions can be specific to the disease of interest and could reflect the clinical severity. Therefore, the investigator propose that whole brain parcellation of diffusion MRI can be used to improve diagnosis and prediction of clinical outcomes in Parkinson's Disease. 1. A regression model between clinical severity and two year clinical outcomes and diffusion properties from multiple parcellated regions will be developed. 2. Blind validation will be performed.
NCT04837313
Parkinson's disease(PD) may cause the autonomic nervous system's improper functioning, which is responsible for regulating the intestinal tract movement. A certain degree of degeneration of digestive system function can cause PD patients to constipation symptoms. Studies have shown that up to 63 percent of people with Parkinson's disease experience constipation. What is more, medications for PD, including levodopa and dopamine agonist, can also cause constipation. In recent years, an increasing number of studies have been conducted to investigate gut microflora and their influence on the central nervous system. Furthermore, some studies of Parkinson's disease have confirmed that gut microflora plays a vital role in the occurrence and development of Parkinson's disease. The purpose of this study is to evaluate the efficacy and safety of fecal microbiota transplantation in the treatment of constipation symptoms in patients with Parkinson's disease receiving a steady dose of levodopa. We will also analyze intestinal flora diversity in patients with Parkinson's disease with constipation. The investigation of the gut microbiome may emerge as a new therapeutic measure to treat constipation associate with Parkinson's disease.
NCT04737811
Purpose of the study is the validity and reliability of the Turkish version of the Swallowing Disturbance Questionnaire (SDQ-T), so that it would be used as an assessment tool for Turkish Parkinson Disease's (PD) patients. Despite being translated and validated in many languages, there is no validated Turkish version of SDQ to measure the severity of dysphagia in PD.
NCT04986020
The study will use routine computer tomography (CT), magnetic resonance spectroscopy (MRI) and nuclear medicine (NM) brain imaging data to produce new diagnostic tests for the onset of Parkinson's disease. This will enable hopefully earlier diagnosis than is currently possible. This will entail the analysis of anonymised CT/MRI/NM brain images collected prior to the point when these subjects were diagnosed with PD.
NCT04472130
With the increase in life expectancy of our population due to advancement of medical diagnosis and treatments, the incidence of age dependent neurodegenerative diseases increased, including Alzheimer's disease (AD), parkinsonian syndromes (PS), small vessel disease (SVD) and motor neuron disease (MND). In spite of the progress of knowing the pathogenesis of various neurodegenerative diseases at molecular and genetic level, they are still very incompletely understood and often cause diagnostic and therapeutic challenges to physicians. Due to the overlapping presentation and similar brain pathology, especially in the early stage of the diseases, it is difficult to differentiate idiopathic Parkinson's disease (iPD) from atypical parkinsonian syndromes, such as multiple system atrophy (MSA) and progressive supranuclear palsy (PSP). Similarly, distinguishing AD from other dementia syndromes including frontotemporal dementia (FTD), dementia with Lewy Bodies (DLB), corticobasal degeneration (CBD) and vascular dementia can be difficult. It is necessary to develop accurate and comprehensive diagnostic tests to properly prognosticate the diseases, start treatments in early stage of the diseases and maximize the accuracy of drug trials for more effective preventive and therapeutic measures for these neurodegenerative diseases. Therefore, the registry aims to generate a large database of cognitive, behavioral, lifestyle and psychological information of the subjects who suffered from neurodegenerative diseases, as well as to examine the genetic basis of neurodegenerative diseases to help decode the pathogenic mechanisms of the diseases. The registry may provide important information to understand symptom development of the neurodegenerative diseases, in which may help physicians to diagnose the diseases more accurately and provide better treatment plans.
NCT03864393
Sustained ambulation is a challenge for individuals with Parkinson's disease (PD) as walking economy is frequently compromised. There are also various disease-related skeletal muscle alterations that may contribute to performance fatigability during ambulation. Concomitantly, individuals with PD experience substantial difficulty maintaining sustained forward progression at push-off during the gait cycle due to diminished force production. Exercise is commonly prescribed for these individuals, though traditional exercise approaches to PD have often applied a "one impairment-one modality" paradigm that addresses each impairment separately. Interventions to optimize movement should facilitate an individual's response to the challenge of responding to a complex interplay of constraints that are also specific to a task and its environmental context. Thus, there are multiple concurrent targets for exercise interventions that may not fit easily within a "one impairment-one modality" model. A multimodal intervention is designed to address an array of constraining impairments concurrently. However, the evidence-base for multimodal exercise approaches is still developing and far from conclusive. The purpose of this study is to demonstrate that multimodal overground locomotion training (OLT) can promote walking economy during sustained overground ambulation in individuals with PD, and produce concurrent secondary effects that decrease performance fatigability and increase propulsion. The aims of this study are to 1) Evaluate walking economy during sustained overground walking after 12 weeks of multimodal OLT, 2) Evaluate secondary effects of OLT.
NCT04974034
Bradykinesia is a key parkinsonian feature yet subjectively assessed by the MDS-UPDRS score, making reproducible measurements and follow-up challenging. In a Movement Disorder Unit, the investigators acquired a large database of videos showing parkinsonian patients performing Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) part III protocols. Using a Deep Learning approach on these videos, the investigators aimed to develop a tool to compute an objective score of bradykinesia from the three upper limb tests described in the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) part III.
NCT04426903
The study is an adaptation of the Long Lasting Memories (LLM) (NCT02267499) and the subsequent LLM Care (NCT02313935) projects in patients with Parkinson's Disease (PD). The study aims to examine the viability and any potential benefits of cognitive and physical training, as offered via the ICT-based (non-pharmacological) intervention of LLM Care, on people with PD. It is worth investigating whether this intervention can offer a better quality of life in patients with PD and counterbalance the often associated with the PD disease neurodegeneration. To evaluate any physical, cognitive, behavioral, and neuroplastic changes and measure the influence (affective status of participant) of the training on the pathological population, the study utilizes somatometric and neuropsychological assessments and neuroscientific (electroencephalographic, EEG-related) indices, as well as affective computing systems.
NCT04970745

NCT04948684
Dystonia is a disabling symptom affecting both patients with idiopathic Parkinson's disease (PD) and atypical parkinsonism (AP). Botulinum toxinum (BoNT), by blocking muscle contraction, is a possible treatment for focal dystonia. The benefit of BoNT treatment has been proven in some focal dystonia associated with PD or AP. The investigators aim to give an overview of the efficacy of BoNT in a variety of focal dystonia in a large cohort of parkinsonian patients.
NCT04946760
Parkinson Disease is a degenerative process that affects millions each year, and has devastating effects on patients and their families. The mobility symptoms that manifest as the disease progresses can result in social isolation as patients may be embarrassed or fear falling in public. One of the common risks resulting from the PD is falls. Falling in PD is primarily related to musculoskeletal issues such as muscular rigidity, postural instability \& stooped posture. These kinds of manifestations should be amenable to treatment with OMT. There are studies showing the positive impact that OMT has on gait in PD, and a study showing improvement in balance in non-PD subjects. This investigation is designed to address these components via the following specific aims: 1. Identify the effects of a Neck-down OMT (OMT-ND) protocol on gait kinematics and postural control in Parkinson disease The investigators hypothesize that the application of an OMT protocol will improve gait kinematics and increase subjects' ability to respond to a postural challenge. The theoretical mechanism for this is due to the improved joint flexibility, improved proprioception and decreased muscle co-activation. 2. Determine the efficacy of Whole-body OMT (OMT-WB) protocol including cranial manipulation on gait kinematics and postural control in Parkinson disease The investigators hypothesize that the addition of a cranial manipulation protocol will further improve gait kinematics and increase subjects' ability to respond to a postural challenge. The theoretical mechanism for this is due to the improved arterial blood flow to the brain, which results from improving the cranial bone motion, maximizing venous drainage, and reducing any restrictions around the vestibular system.
NCT04942392
Dance as a treatment to support physical, cognitive and emotional functioning, has gained increased acceptance as a healthcare intervention for people with Parkinson's Disease (PD). The impact of the COVID-19 pandemic has been far reaching with devastating effects for at-risk populations. To find alternative and safe treatment delivery options during the pandemic has been of outmost importance. This mixed-methods, feasibility study on digital for people with Parkinson's Disease aimed to investigate: (1) the feasibility and safety of a digital home-based dance intervention for people with PD; (2) change in self-reported quality of life, cognitive complaints, psychological health and fatigue; and (3) the experience of digital dance for people with PD. Twenty-three participants partook in 10 weekly digital dance classes at home via zoom. Feasibility outcomes measures were administered at post-test. Pre-post changes in self-reported quality of life, cognitive complaints, psychological health and fatigue were measured, as well as the experience of digital dance via focus groups.
