Active clinical trials for "Parkinson Disease"

The consequences of COVID-19 in these already fragile patients should be evaluated. It will be important to appreciate the confinement consequences imposed on the patient on the course and impact of the disease. These consequences can be assessed by the end of confinement and 6 months after the latter is lifted.

Parkinson's disease (PD) is a neurological condition, which affects the brain. PD gets worse over time, but how quickly it progresses varies a lot from person to person. Some symptoms of PD are tremors, stiffness, and slowness of movement. The purpose of this study is to see how feasible and how satisfied participants/caregivers/investigators are with video-assisted telenursing use in nurse support programs with LCIG. LCIG is an approved drug to treat PD. Approximately 50 adult participants with advanced PD will be enrolled in the study at approximately 10 sites across the world. The study has 2 groups. In one group, around 25 participants will receive nurse support using video devices. In the second group, around 25 participants will receive nurse support without using video devices. All participants will attend a baseline visit and follow up visits at Week 4 and Week 12. The planned observation period will be 12 weeks. Participants who are prescribed LCIG by their physicians will have three study related visits. Participants, caregivers, and investigators will be asked to complete questionnaires for the study.

The aim of the study is to investigate the change of lower and upper extremity skills with dual task in Parkinson's disease patients and to determine the differences between Parkinson's disease patients with different stages of disease and the healthy controls regarding the change of lower and upper extremity skills with dual task.

Parkinson's disease is characterized by cardinal motor signs and motor freezing, gait, posture and balance disorder. About 80% of the causes of falls in Parkinson's patients are due to postural instability and motor freezing, and patients' quality of life is significantly affected. Loss of balance and falls, which are frequently experienced in Parkinson's patients, cause individuals to feel insecure during activities. It is thought that the quality of life of PD patients whose movements are restricted due to the fear of falling may also be negatively affected. The neutrophil/lymphocyte ratio is a marker of peripheral inflammation. The relationship of peripheral inflammation to balance, activity-specific balance confidence, and quality of life in individuals is unclear. The aim of this study was to compare balance, activity-specific balance confidence, quality of life, and the relationship between neutrophil/lymphocyte ratio in Parkinson's patients with and without freezing.

About 60% of Parkinson's Disease (PD) patients have REM sleep Behavior Disorder (RBD), a parasomnia characterized by partial or complete loss of REM sleep muscle atonia and dream-enacting behaviors, usually associated to vivid dreams. The REM Sleep without atonia is the polysomnographic hallmark of RBD, and its quantification is necessary for the diagnosis. RBD in PD is believed to be a marker of a more widespread degenerative process and a marker of malignant phenotype. Therefore, PD patients with RBD (PD-RBD) are more severely impaired in both motor and non-motor domains, compared to those without RBD, with an increased risk of dementia. However, little is know about the relationship between the evolution of RBD, clinic and video-polysomnographic, and the progression of PD. Besides, an improvement of RBD symptoms is anecdotally reported in PD patients over time. Longitudinal evaluation of RBD in PD, assessed by questionnaires, led to controversial results, but so far, no longitudinal vPSG study has been performed in PD-RBD population. Thus, the main objective of this study is to longitudinally evaluate clinical and video-polysomnographic features of RBD, including measure of REM Sleep without atonia, in patients with PD-RBD, after three years from the diagnosis of RBD, in order to ascertain whether RBD features remain stable over time. The possible remission of RBD with the progression of PD would question indeed its reliability as prognostic bio-marker.

Speech is an important indicator of motor function and movement coordination and can be extremely sensitive to involvement in the course of neurologic diseases. The aim of this project is to discover for the first time using simple speech recording and high end pattern analysis preclinical stages of disabling central nervous system disorders including Parkinson's disease and other alpha-synucleinopathies in "at high risk" patients with REM sleep behavior disorder and thus provide one essential prerequisite for trials on REM sleep behavior disorder with preventive therapy.

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).

The primary objective of this study is to determine if the diagnostic performance of DaTscan™ single photon emission computed tomography (SPECT) imaging is different in non-Caucasian subjects compared with Caucasian subjects with movement disorders.

AIM: Investigate wether there are differences in the parasympathetic nervous system in Parkinsons patients compared to controls. MATERIALS AND METHODS: We use the tracer [11C]donepezil to image the parasympathetic nervous system. The Investigators will include 20 Parkinsons patients and 20 healthy controls aged 40-80 in our study. The participants will receive a careful medical examination, including a neurological examination, as part of the inclusion process. The subjects also have an MRI scan of the brain. Then PET/CT scans with [11C]donepezil are conducted - once for the upper abdominal region and once for the head region. For evaluating the function of the parasympathetic nervous system gastric emptying time, heart rate variability and salivary flow will be measured. These measureless will be correlated to the PET findings. PERSPECTIVES: The study will potentially result in the development of a PET ligand for imaging the parasympathetic nervous system. This will have applications for research in Parkinson's disease, diabetes, heart disease and other disorders, in which the autonomic nervous system is involved

The ERD and ERS patterns of coordination between the STN and cortical regions in the termination of volitional movement in PD patients.
