Active clinical trials for "Parkinson Disease"

Parkinson's disease (PD) is the second most frequently appearing neurodegenerative disease. It is a progressive disease of the central nervous system (CNS) and affects around 1% of people over 60 years old. During the progression decline of substantia nigra and deficits of dopamine are observed. The diagnosis is usually based on the motor symptoms such as resting tremor, bradykinesia, muscle stiffness, and postural instability. Common intercurrent symptoms are psychiatric problems like depression or dementia (1). Pharmacotherapy, for example, L-dopa or deep brain stimulation (DBS) are usually used to reduce the motor symptoms (2). From many years the influence of insufficient vitamin D3 levels in human is investigated. In recent publications it was proved that the deficiency of vitamin D3 may lead to generation of reactive oxygen species that influence negatively on mitochondria. That may lead to increased muscle atrophy (3,4). Deficiency of vitamin D3 may be also connected with depression, dementia or the progression of neurodegenerative diseases (5). Moreover, recently studies proved that PD patients have low concentration of serum vitamin D3 (5), increased serum homocysteine (6) and abnormalities in kynurenine pathway (7). It has beed proved that many forms of physical activity in PD patients improves mobility, static and dynamic balance but also may reduce the non-motor symptoms (8,9).

Pain is one of the non-motor symptoms of Parkinson's disease still poorly known and misdiagnosed and its management is complex. This encourage to explore new non-drug therapeutic paths, such as foot reflexology (FR). the present study proposed a comparison of the evolution of different parameters, quantitative and qualitative, to identify biomarkers and highlight the specific effect of FR on pain, compared to sham massage.

Mild cognitive impairment is experienced by approximately 30% of patients with Parkinson's disease (PD-MCI), often affecting executive functions. There is currently no pharmacological treatment available for PD-MCI and non-pharmacological treatments are still scarce. The aim of this study was to test preliminary efficacy/effectiveness of two home-based cognitive interventions adapted for patients with PD-MCI: Goal Management Training, adapted for PD-MCI (Adapted-GMT), and a psychoeducation program combined with mindfulness exercises. Twelve persons with PD-MCI with executive dysfunctions, as measured by extensive neuropsychological evaluation, were randomly assigned to one of two intervention groups. Both groups received five sessions each lasting 60-90 minutes for five weeks, in presence of the caregiver. Measures were collected at baseline, mid-point, at one-week, four-week and 12-week follow-ups. Primary outcomes were executive functions assessed by subjective (DEX questionnaire patient- and caregiver-rated) and objective (Zoo Map Test) measures. Secondary outcomes included quality of life (PDQ-39), global cognition (DRS-II), and neuropsychiatric symptoms (NPI-12). Safety data (fatigue, medication change and compliance) were also recorded. Repeated measures ANCOVAs were applied to outcomes. Both groups significantly ameliorated executive functions overtime as indicated by improvements in DEX-patient and DEX-caregiver scores. PDQ-39 scores decreased at the four-week follow-up in the Psychoeducation/Mindfulness group whereas they were maintained in the Adapted-GMT group. All other measures were maintained over time in both groups. Adapted-GMT and Psychoeducation/Mindfulness groups both improved executive functioning. This is one of the first studies to test home-based approaches, tailored to the participant's cognitive needs, and involving caregivers.

This is a randomized, open-label, 2-sequence, 2-treatment cross-over study in healthy adult subjects. Rotigotine PK profiles will be obtained from all subjects after both a single dose of 28 mg LY03003 and 1 week of 4 mg q24h NEUPRO® patch. Subjects will be randomized 1:1 to 1 of the 2 treatment sequences.

The goal of this clinical trial study is to learn about the effect of aquatic exercise in parkinson's patients. The main questions it aims to answer are: What is the effect of exercise in water on balance in parkinson's patients? What is the effect of exercise in water on muscle strength in parkinson's patients? What is the effect of exercise in water on flexibility in parkinson's patients? Parkinson's patients in this study will do some functional tests. One group of them will do exercises in water 3 times weekly for 8 weeks.

When postural imbalance and gait difficulties emerge in subjects with Parkinson disease, patients are typically referred for a number of physical therapy sessions. However, there is a critical gap in clinical practice on what to do once patients have completed their therapy sessions. To fill this gap, the study team has developed a standing table with a tabletop system that encourages weight shifting during upright standing ("dynamic standing table"), and therefore may be a unique means to increase daily physical activity by integrating the system with routine desktop activities of daily living. The purpose of this study is to determine whether a post-physical therapy in-home physical activity program using the dynamic standing table (as an adjunct to post-physical therapy standard of care-weekly physical activity group sessions) is effective in sustaining the mobility benefits of physical therapy in individuals with Parkinson disease.

Cognitive impairment in Parkinson's disease (PD) has far-reaching effects on both motor outcomes and quality of life in PD patients. Furthermore, deep brain stimulation (DBS), now an evidence-based treatment for certain cases of PD, has the risk of causing deficits in multiple areas of cognition. As such, the purpose of this study is to understand the neuroanatomical and neurophysiologic basis for impaired cognition in PD. The aim is to identify neural correlates of cognition by measuring brain signal activity while PD patients are engaged in cognition on a computer.

The purpose of this feasibility study is to preliminarily evaluate the effects of Tai Chi - a mind-body exercise - on motor and cognitive function as well as quality of life in individuals recently diagnosed with Parkinson's disease (PD).

The objective of this study is to investigate the effect of safinamide on levodopa blood levels, both after single and multiple dosing of safinamide . A further objective of the study is to assess the safety and tolerability of safinamide when given together with levodopa in the applied regimen. For that purpose, all study participants will undergo intensive blood sampling for investigation of levodopa levels and various tolerability examinations, such as the measurement of vital signs (blood pressure, pulse, body temperature), recording of ECGs and questioning to find out how the study participants are feeling. Furthermore, blood samples will be drawn and urine tests will be performed repeatedly for safety purpose during the course of the study. The results of this clinical trial may be used for the drug registration of safinamide in the future.

The purpose of this study is to assess the recharge feature of the Activa RC System in patients who are receiving Deep Brain Stimulation (DBS) for Parkinson's Disease (PD), Essential Tremor (ET), or dystonia.
