Active clinical trials for "Parkinson Disease"

The objective of this trial was to assess subject preference for PARCOPA, carbidopa/levodopa Orally Disintegrating Tablets (ODT), compared with conventional carbidopa/levodopa tablets, in subjects with stable Parkinson's disease.

This study will examine and compare blood samples from healthy volunteers and patients with Parkinson's disease to identify abnormalities associated with Parkinson's disease. Disease symptoms include slowness of movement, hand or leg shaking, and stiffness. Some patients have difficulty with balance. Information from this study may provide information on how Parkinson's disease affects the brain and body, and may help lead to a test for earlier diagnosis. Healthy volunteers and patients with Parkinson's disease who are 18 years of age or older may enroll in this study. Participants will undergo the following procedures: Physical examination, including evaluation of strength, feeling, coordination, and balance Blood drawing: 150 milliliters (about 10 tablespoons) of blood will be drawn Personal and family medical history Consent to access medical records for research purposes Blood samples will be examined for: Genetic analysis Study of specific proteins and lipids Study of mitochondria (parts of cells that make energy)

Lower respiratory tract infections are one of the main hospitalization or mortality cause in idiopathic Parkinson's disease. Because of akinesia and articular rigidity these patient develop restrictive syndrome by reduction in the thoraco-lung compliance.The consequence is a progressive loss of the aerobic physical abilities and infection. The myotensive technique of active muscular stretching seem to increase the range of motion in healthy subject but also in patient with chronic bronchiotisis . These technics also increase the vital respiratory capacity and re enforce the muscles.So adding these technics during the period when the Parkinson's disease patient is stable would be a way of improvement .

The purpose of this study is to evaluate disease progression in persons with early Parkinson disease, as assessed by digital and electronic sensor data collection to be correlated with typical clinical assessments.

The purpose of this study is to assess whether tear secretion in patients with Parkinson's disease will be altered to exhibit a characteristic or diagnostic biomarker profile, that will be reflected in changes in the protein composition of tear fluid, which can be measured relatively easily, cost-effectively, and non-invasively. Tear fluid samples will be collected from Parkinson's patients, and through biochemical assays, the profile of proteins in tears will be characterized and compared to that from control subjects. The profiles will be analyzed with respect to any differences between Parkinson's patients and control subjects. If differences appear, the levels of these potential biomarkers in Parkinson's patients will be compared to the severity of their disease.

Parkinson's disease (PD) is usually responsible of cognitive and behavioral non-motor signs with a major impact on the quality of life. Social cognition is a complex system relying on emotion recognition (neurons mirror system, NMS), the theory of mind (with its two parts: emotional and cognitive), but also on the social and cultural environment and the personal history. The first step in this model is represented by the NMS, which seems to be altered in PD patients for both positive and negative emotions as shown in our preliminary study. The investigator purpose is to investigate the role of the treatment (levodopa and deep brain stimulation) on the functioning of the NMS.

In Parkinson's disease (PD), alpha-synuclein accumulation in cutaneous autonomic pilomotor and sudomotor nerve fibers has been linked to autonomic nervous system disturbances even in the early stages of the disease. The investigators recently introduced a non-invasive technique to assess autonomic adrenergic fiber function using the quantitative pilomotor axon-reflex test (QPART). In the present study the investigators aim to assess the association between alpha-synuclein mediated structural autonomic nerve fiber damage and nerve function in PD, elucidate the role of neuropathy progression during the early disease stages, and test reproducibility and external validity of pilomotor function assessment using quantitative pilomotor axon-reflex test (QPART) and sudomotor function via quantitative direct and indirect test of sudomotor function (QDIRT). A prospective controlled study will be conducted in four sites (Dresden, Germany; Berlin, Germany; Budapest, Hungary; Boston, USA). A total of 52 male and female patients with idiopathic PD (Hoehn&Yahr 1-2) and 52 age- and sex-matched healthy controls will be recruited. Pilomotor function will be evaluated after iontophoresis of phenylephrine on the dorsal forearm to elicit a cutaneous axon-reflex mediated response (goosebumps). Silicone impressions of the stimulated area will be obtained, scanned and quantified for pilomotor muscle impressions by number, impression size and area of axon-reflex pilomotor erection spread. Sudomotor function will be evaluated after axon-reflex stimulation via iontophoresis of acetylcholine on the dorsal forearm. Stained sweat droplets will be captured using repeated digital photography and will be quantified over time for droplet number and axon-reflex spread. Sympathetic skin responses following deep inspiration will be analyzed using skin conductance quantification. Testing and evaluation of autonomic and motor symptoms will be performed at baseline, after 2 weeks, 1 year, 2 years and 3 years. Skin biopsies will be obtained at baseline and after 3 years and will be analyzed for nerve fiber density and alpha-synuclein accumulation. The investigators expect that this study will unveil whether progression of autonomic nerve dysfunction assessed via pilomotor and sudomotor axon-reflex tests is related to progression of autonomic symptom severity and alpha-synuclein deposition in PD. Additionally, potential applications of the used techniques include interventional studies evaluating disease-modifying approaches and clinical assessment of autonomic dysfunction in patients with PD.

Idiopathic Parkinson's disease (IPD) is the second most frequent neurodegenerative disease. Its association with osteroporosis and fragility fracture is now clearly demonstrated, but the determinants of this osteoporosis are yet to be explained. Our aim was to study factors associated with volumetric bone mineral density (vBMD) and bone microstructure at the tibia and radius in IPD.

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.

The kinesiophobia; defined as irrational fear of movement, which may occur after painful injury and reduce physical activity. It develops the idea that movement in individuals will cause re-injury and cause additional pain to existing pain. Studies have shown that this situation leads to a decrease in physical fitness, avoidance of activity, decrease in quality of life and even depression in the long term. It is known that functional problems such as balance problems and decrease in physical activity level occur in patients with Parkinson's disease. However, in the literature, there is no study investigating the presence of kinesiophobia in patients with Parkinson's disease. Therefore, the aims of our study were to 1) determine the presence / absence of kinesiophobia in patients with Parkinson's disease 2) determine the relationship between kinesiophobia and falling, balance, physical activity level in the presence of kinesiophobia.
