Active clinical trials for "Parkinson Disease"

Purpose/Goal: To determine if a remote computerized cognitive remediation program (CRT) can stabilize or improve cognitive functioning in a group of patients from the New York Institute of Technology Academic Health Care Center with Parkinson's disease (PD) after three months of intervention. Hypothesis: Patients with PD who present with current cognitive deficits will show improvement in such deficits after three months of participation in a remotely supervised structured Cognitive Remediation Therapy Program (CRT) compared to control subjects with PD who receive treatment as usual. Research design: Pilot study. Prospective randomized treatment and control comparison pre-post study.

Levodopa (LD) is an effective treatment to control symptoms of Parkinson's disease (PD). However, the response to (the effectiveness) LD changes over time and patients require higher and more frequent LD doses for treatment. The purpose of this study is to identify what reasons or causes might influence the changes in LD effectiveness, particularly if intestinal bacteria contribute to the breakdown of LD in patients with PD. This study is an observational cohort proof-of-concept study that follows PD patients who take PD at high-frequency doses and low-frequency doses. . Each PD patient will have a household healthy control/spouse enrolled into the study. Single patients with no spouse will still be eligible to enroll.

Gait disturbances and movement restrictions occur frequently in Parkinson's disease. Patient-centered monitoring with objective aids in the patient's daily life, supports and promotes therapy decisions made by physicians and patients. Technical, sensor-based monitoring has the potential to generate objective target parameters at any point in time during therapy (patient journey), representing the state of health and its progression, and to make this information available to physicians and patients via telemedical data management. In this study, the gait analysis system "Mobile GaitLab Home 2.0", consisting of sensors for gait data acquisition, a smartphone application for study participants (Mobile GaitLab app) and a web portal for physicians (Mobile GaitLab portal) is used for data collection. The research question is divided into three sub-objectives: First, the study explores and tests how technically generated parameters of sensor-based gait analysis can map the symptom "bradykinesis". The second goal is the explorative investigation of how a tele-health service support with low-threshold access to medical professionals, can be integrated into the care process. The third goal is the implementation evaluation of the technological developments. Here, it is examined to determine the extent to which the implementation of gait data and patient feedback (PROMs) in the patient-centered care process within the framework of clinical decision support contributes to early gait-associated therapy optimization and thus improves the general health of patients and how initial indications of positive care effects for patients can be derived. During a 60-day observation phase, study participants use the gait analysis system, which records their gait pattern throughout the day and collects data via the Mobile GaitLab app. Study participants are asked to perform standardized gait tests in the home environment several times a day, in addition to continuous measurements during the awake phase. Frequency of data collection is controlled by Mobile GaitLab Home 2.0 and can be flexibly adjusted to the study participant's health status and therapy. The Mobile GaitLab app uses questionnaires to record data on gait safety, activity, general well-being, and events relevant to the disease. An evaluation of these data (PROMs) and the results from the gait analyses, are visualized for the study participants via the Mobile GaitLab app.

It has been shown that patients with Parkinson's disease (PD) have impaired kinaesthesia and haptic perception of the upper limbs. In PD patients, these impairments might be involved in the development of hypometria or bradykinesia and may play a role in postural deficits, thereby significantly contributing to the overall disability level. Dedicated conventional or robot-assisted training might improve sensory-motor function in PD patients. In order to provide efficient robot-assisted therapy, robotic devices have to be able to tailor the therapy difficulty to the individual impairment profile of each patient. For difficulty adaptation in robot-assisted therapy, it is important to assess the impairment profiles with the same robotic platform that would be used for therapy, therefore minimizing costs or potential errors coming from the use of different devices. However, up to now, little emphasis has been placed on providing sensory-motor robot-assisted therapy for the upper limbs to persons with PD based on their individual level of impairment. The aim of this study is therefore to evaluate if the assessments of sensory-motor hand function implemented on a robotic device for hand rehabilitation, i.e. the ReHapticKnob, are suitable to measure the impairments of kinaesthesia and haptic perception observed in subjects with Parkinson's disease. If the assessments implemented in the ReHapticKnob are sensitive enough to detect a difference between the sensory-motor function of PD patients and healthy subjects, the device might in the future be used to assess improvements before and after sensory-motor therapy. This is a necessary step before the investigators can use these assessments to tailor the difficulty level of the therapy performed with the ReHapticKnob and to investigate the benefits and impact of such a therapy on the kinaesthetic and haptic impairments of persons with PD.

The aim of the project is to develop the first alpha-synuclein (a-syn)-specific PET tracer. The research phase will exploit ACI's proprietary MorphomerTM library and extensively optimized screening workflow. Promising PET-tracer candidates will be tested for their ability in detecting a-syn pathology in patients with a range of Parkinsonian conditions with different a-syn levels and distributions, comprising hereditary forms of PD and other synucleinopathies.

The sequence effect (SE), defined as a reduction in amplitude of repetitive movements, is a common clinical feature of Parkinson's disease (PD), being a major contributor to freezing of gait (FOG). During walking, SE manifests as a step-by-step reduction in step length when approaching a turn or gait destination (dSE). The investigators studied the effect of a 4-week rehabilitation program on the destination sequence effect in patients affected by Parkinson's disease with and without Freezing of Gait. All subjects were evaluated with inertial gait analysis for dSE recording.

Parkinson's Disease (PD) is a progressive neurodegenerative disease characterized clinically by bradykinesia, resting tremor, rigidity, and postural instability. Little is known about the mechanisms underlying neuronal degeneration in PD and currently, no treatment is available to halt disease progression in PD. The pathophysiological characterisation of phenomena occurring in the time window between the pathological start of the disease and the onset of motor symptoms is crucial to develop potential neuroprotective agents. Several genes have been discovered providing important insights on the pathogenesis of PD. Mutations of Leucine-rich repeat kinase 2 (LRRK2) are associated with 2-5% of all PD cases in North American Caucasians. LRRK2 is an enzyme that in humans is encoded by the autosomal dominant Parkinson's disease-8 (PARK8) gene, which is associated with an increased risk of PD. Clinical and digital biomarkers, blood and cerebrospinal fluid (CSF) biomarkers and molecular positron emission tomography (PET) imaging, with specific radioligands, provide invaluable insights to help understand and characterise disease pathophysiology. The investigators aim to characterize molecular phenomena underlying LRRK2 PD with the hope of providing further insights into possible mechanisms taking place in PD and to help identify targets for disease-modifying therapeutics.

The aim of this study is to determine the fall and balance conditions of Parkinson's patients according to their urinary complaints.

The objective of this clinical investigation is to characterize the clinical performance of Abbott's Clinician Programmer Electrode Screening Mode tool (InformityTM tool) in programming InfinityTM deep brain stimulation (DBS) systems for patients with Parkinson's disease (PD) or essential tremor (ET).

The study would be designed as a multi-center cross-sectional investigation on the prevalence of Wearing-off in Parkinson's patients in Shanghai as well as related influencing factors.
