Active clinical trials for "Parkinson Disease"

This study includes 35 PD patients who underwent submandibular gland needle biopsy. 25 neurologically healthy patients of the local otolaryngological clinic, in whom submandibular gland needle biopsy was performed due to a clinical indication, serve as controls.

To investigate the relationship between serum cystatin C and dopamine receptor(DAT) loss in patients with parkinson's disease(PD)

Perioperative neurocognitive disorders(PND) is common to see in elderly patients. Although PND increases patient mortality as well as hospitalization time, apparent inflammatory factors, and related mechanisms are still unknown. Metabolites could reveal chemical fingerprints left behind by cellular processes, which in turn provide a new aspect to understand the biological process behind. we aim to found the metabolomics can aid the development of diagnostic markers of PND screening, early detection, and further, provide a basis for disease prevention and treatment.

This a usability study of a wearable sensor platform that utilizes a smartwatch to periodically record motion data. That data is processed in a connected smartphone and translated into symptom scores for dyskinesia, slowness, and tremor. The research subjects will use the wearable system over the course of five weeks, during which a change in therapy regimen is prescribed by the physician. Research analysis will be focused on patient and clinician experiences with the app and its reports.

This study plans to analyze the molecular and clinical mechanisms of the relationship between the GBA mutations and Parkinson's disease. This will be assessed through the use of advanced neuroimaging techniques called PET (positron emission tomography) to study the accumulation of the tau protein and the dysfunction of acetylcholine and dopamine in the brain of people with a mutation in the GBA gene, with and without Parkinson's disease. The ingestigators will also use a technology-based assessment to study the typing patterns as possible biomarkers of early motor dysfunctions.

Background: Parkinson's Disease and the Atypical Parkinsonian Disorder (like Multiple System Atrophy, Progressive Supranuclear Palsy, Corticobasal Degeneration, Lewy Body Dementia) are disease entities with partly common symptomatology. Especially very early in the course of disease, the differentiation between both disease entities can be challenging, even for specialists in the field of movement disorder. However, the establishment of a correct diagnosis is very important for adequate patientcounseling, treatment and the correct inclusion of patients in research trials. Ancillary diagnostic investigations are looked upon to aid in this diagnostic dilemma. Objective: To investigate the value of ancillary diagnostic investigations, more specific MRI, analysis of cerebrospinal fluids and a second opinion in a specialized movement disorder centre, to differentiate Parkinson's disease and the Atypical Parkisonisonian disorder.

In Italy affected people are 200,000 and every year Parkinson new cases are 10,000. Aging is the principle risk factor of Parkinson with the possibility of its development doubling every five years after 65. Because of the increase of the social longevity and aging as the main risk factor, there are many repercussions on the health system (hospital stays and pharmaceutical costs) as on the social system (assistance- related problems). Parkinson's disease exerts an extremely negative impact on life's quality of the patient. In fact, because of Parkinson symptoms (tremor, dribble, etc), patient's social life will be reduced with the consequent development of the depression. Consequently, the early detection and treatment of Parkinson's is necessary. To achieve this goal, Apolipoprotein D (ApoD) in human serum as a marker of the oxidative stress-inflammation vicious cycle seems most promising candidate for diagnosis.

The present study is part of an international program and deals with the translation and validation program for the Italian version of the MDS-UPDRS. The program will be articulated in three steps: Phase I: translation and back-translation of the MDS-UPDRS in Italian (completed) Phase II: Cognitive testing. This step is aimed at a preliminary testing of a subset of potentially culturally sensitive items in a limited set of PD patients (approximately 10). Should this phase identify issues in the understanding and ease of use of some items a revised translation of some individual items might be envisaged. Phase III: large validation testing: this phase will involve 350 PD patients from 12-14 Italian PD centres. The IRIS protocol deals with phase II and III of the program.

The purpose of the Parkinson's disease Registry is to develop a national and international database of persons with Parkinson's disease (PD). The Registry will be used to facilitate the development of new therapies and healthcare services to improve the quality of life for people with PD. It will also be a means for investigators in the field of PD to quickly identify and notify subjects about other research studies for which they are eligible. Objectives include: Assess current treatment approaches and develop best-practice guidelines Track the functional abilities, access to healthcare and cost of illness of people with PD over time Drive the development of innovative research projects Accelerate the process of informing patients of research projects for which they may be eligible

This pilot study will assess the feasibility of using heavy water as a safe 'tracer' for biomarker studies of diseases of the brain and spinal cord, that, together, are also called the central nervous system (CNS). Heavy water, also called deuterated water or D20, is the same as normal drinking water except the hydrogen atoms have been replaced by deuterium, a naturally occurring isotope of hydrogen. In particular, this study will use heavy water to define: 1) The rate of immune cell proliferation (growth) in the cerebrospinal fluid (CSF) compared to blood. This study will be examining a particular type of immune cell called T lymphocytes. 2) This study will also examine selected molecules generated by nerve cells of the CNS to understand their rate of secretion and turnover in healthy control participants, HIV-1-infected participants and participants with a non-HIV-related neurodegenerative disease such as Parkinson's disease (PD). This study will involve the administration of heavy water orally for either seven days, 12 days or six weeks. Measurements will be taken by lumbar puncture (LP, also known as a spinal tap). Blood (approximately five tablespoons per visit) will also be obtained at each of the lumbar puncture appointments. If this method can be used to establish the rates of immune cell turnover and the production rates of neuronal molecules using cerebrospinal fluid, it will provide unique data that is important to understand chronic neurodegenerative conditions, like PD, and to measure responses to targeted therapies. Hypothesis: D2O, administered orally, can be used to measure the proliferation rates of CSF T cells (and, eventually, of their major phenotypic subsets). D2O can be used to assess the turnover and production rates of CNS constituents that are normally or pathologically shed or secreted into the CSF, including (eventually): cargo molecules transported specifically in neurons in the CNS, such as chromogranin-A and -B, neuregulin-1 (specifically the extracellular secreted ectodomain of neuronal differentiation factor (NDF) isoform type α1, α2, β1, and the acetylcholine receptor inducing activity isoform (ARIA), secreted amyloid precursor protein (sAPP), alpha-synuclein; and APP metabolites amyloid beta (Aβ) 41 and 42.
