Active clinical trials for "Parkinson Disease"

Observational cross-sectional study in PD patients and healthy controls (HC) using an investigational medical device consisting of a passive small intestine microbiome aspiration (SIMBA) system (capsule) that is ingested orally and recovered together with the stools (home recovery) together with blood sampling (during the onsite visit).

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 a single time point. 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.

The aims of this study are to: Evaluate peripheral and central auditory and vestibular function in group of adults with idiopathic PD. Determine the relationship between the presence of significant auditory and vestibular dysfunctions to patients' demographic, clinical (motor and non-motor manifestations) and treatment variables

This study is being done to assess the pharmacokinetics of SCH 900800 in participants with moderate to severe Parkinson's Disease (PD) being treated with L-DOPA.

The objective of this prospective observational cohort study is to answer the following clinically important questions: In patients with a pre-operative history of ICBs, what is the likelihood of improvement or deterioration in ICBs post-operatively? What is the risk of developing post-operative de novo ICBs after Subthalamic Nucleus DBS (STN DBS)? Which factors are important in predicting changes in ICBs after STN DBS? What is the impact of ICBs on carer's quality of life QoL and burden?

To test for the first time the potential of a nicotinic agonist on cognitive symptoms in people with mild cognitive impairment (MCI) in Parkinson's disease (PD), referred to as PD-MCI.

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.

Idiopathic Parkinson's disease (IPD) is a degenerative disease affecting the dopaminergic system. Clinical symptoms of IPD commonly begin after the loss of at least 40 to 50% of striatal dopaminergic terminals (specially putaminal terminals). The Dopamine neuronal transporter (DAT) is a highly expressed protein in the membrane of presynaptic nigrostriatal dopaminergic terminals. The use of a DAT's radioligand in the initial stages of the disease would lead to an early detection of nigral cell loss. Currently, only one DAT's radioligand has obtained marketing authorization in France, the 123I-FPCIT, for use in Single Photon Emission Computed Tomography (SPECT). Otherwise, the Positron Emission Tomography (PET), a more sensitive technology than SPECT with higher resolution has become for a few years the new gold standard for visual analysis and quantification of neurotransmission systems (including the dopaminergic system). A DAT tracer labelled with Carbon 11 ([11C] PE2l) have been developed and is currently used as a reference in various research centers. However, in order to enable a clinical use of this tracer (which currently can't be because of the too short period of Carbon 11), the unit INSERM U930 "Imaging and Brain" in collaboration with the CERRP (Center for Studies and Research on Radiopharmaceuticals) developed a new version of this tracer, labelled with 18-fluor: the [18F] LBT-999. The main goal of this study is to compare the [18F] LBT-999 uptake between a group of patients suffering from a Parkinsonien syndrome to a group healthy volunteers.

This study will assess the relative bioavailability of s.c. infused ND0612 versus jejunally infused CLES in patients with advanced PD.

This is a cross-sectional exploratory study. A total of 25 people with PD, 25 young healthy adults, and 25 middle to older adults will be recruited. Axial segment turning pattern and turning performance will be evaluated in two visits using the Vicon 3D motion analysis system, Gaitup, and 3D motion camera. The independent variables are the initiation timing of the head, upper trunk, pelvis, ankle, and foot when turning and the initiation sequence of turning (% turn). The dependent variables are turning performance, including turning velocity, turning steps, turning step length, turning step width), and stance phase (%).
