Active clinical trials for "Parkinson Disease"

Motor symptom progression in early-stage Parkinson's disease varies substantially between individual patients. This progression correlates poorly with striatal dopamine depletion, which is largely complete four years post-diagnosis. Identification of alternative mechanisms, such as cortical compensatory processes, may enable more accurate predictions of individual motor progression.

Apathy is defined as a lack of feeling, emotion, interest, or concern. Apathy also involves reduction or loss of motivation and goal-directed behavior. Clinically significant apathy, where meaningful activities are given up and quality of life is diminished, is common in people with Parkinson's disease (PD). Many individuals with Parkinson's disease experiencing fluctuations in the severity of their movement problems and medication "off" time. "Off" time refers to periods of the day between doses of PD medication when your motor symptoms (e.g., tremor, stiffness, slowness, walking problems, etc.) are worse and interfere with your ability to complete tasks of daily living. The investigational drug, Istradefylline, is an FDA-approved medication to treat motor fluctuations and "off" time in PD. The purpose of this study is to investigate whether people with Parkinson's disease (PD) who are treated with istradefylline (ISD) show improvements in motivation and apathy over a 12-week period. Specifically, we wish to see whether people with PD who are treated with ISD engage in more physical and recreational activities, such as hobbies and other interests.

Stress has been implicated as a trigger of many diseases, throughout different mechanisms. Potentially traumatic/stressful events exposure might be a factor that triggers subclinical disabilities related to PD becoming evident to the patient. In this observational study, the investigators will evaluate with a validated events exposure questionnaire the occurrence and severity of potentially traumatic or stressful events in Parkinson's disease patients and in patients with recent-onset parkinsonism.

The objective of this study is to evaluate the adhesion of the test product when compared to the reference product following a single transdermal application.

This study consists of two parts. Part A will evaluate the safety and tolerability of multiple doses of OXB-102 (AXO-Lenti-PD) in participants with Parkinson's disease. Part B will assess the safety and efficacy of the selected dose of OXB-102 in participants with Parkinson's disease.

The primary objective of this study is to evaluate the safety and tolerability of a range of single and 13 repeated doses of BIIB054, administered as intravenous (IV) infusion, in Japanese participants with Parkinson's disease (PD). The secondary objectives are to evaluate the immunogenicity, and serum pharmacokinetics (PK) profile of BIIB054 after single and multiple dose administration.

This is a multicenter, randomized, three-arm, parallel-group, double-blind, placebo-controlled, study to evaluate the efficacy, safety and pharmacokinetics (PK) of pridopidine vs. placebo for the treatment of Levodopa Induced Dyskinesia (LID) in patients with Parkinson Disease.

This pilot study aims to investigate the effects of 8-week SMARTfit training versus conventional physical training on motor function, cognition and brain functional connectivity in individuals with PD. The investigators hypothesize that clinical and physical performance will improve after SMARTfit training more than after conventional physical training.

Parkinson's Disease (PD) is one of the most common neurodegenerative disease. Bradykinesia, tremor, resting tremor and postural instability are the main motor characteristics of this disease. As the disease progresses, mobility, walking, balance are reducing, the risk of falls is increasing and patients become functionally dependent. Along with these symptoms, cognitive functions are also disturbed. The most commonly distorted cognitive functions are executive functions such as planning and reasoning, working memory, episodic memory, attention and visual-spatial skills. Pharmacological and surgical treatments are used in Parkinson's disease. Pharmacologic treatment has a proven effect on motor symptoms, but since there is no approved pharmacologic treatment which has a direct effect on cognitive functions, recent studies suggest non-pharmacological treatments to improve cognitive function. Physiotherapy is also accepted among non-pharmacological treatments. Conventional physiotherapy focuses on optimizing patient independence and safety, focusing on hinting strategies, cognitive movement strategies and exercises utilizing transfers, posture, upper extremity function, balance (and falls), gait, physical capacity and (in)activity. Virtual Reality (VR) technology, a promising commonly used new rehabilitation tool, is a treatment method that can be used as one of the non-pharmacological treatment methods in Parkinson's Disease. In order to understand how neuronal network dysfunction in the Parkinson's Disease leads to clinical symptoms, both the component elements and the interconnections within these networks need to be examined in greater detail. Studies of resting state-fMRI (rs-fMRI) use correlation of activation of brain regions and time series fluctuations between brain regions to give information about connectivity in brain. The purpose of this study is to investigate the therapeutic effects of virtual reality on motor and cognitive symptoms of PD. Furthermore, the investigation of possible effects of this effect on neuroplasticity through functional brain networks is our other objective. This study will be the first study to evaluate the plasticity effect of virtual reality application with rs-fMRI in Parkinson's disease.

The purpose of this study is to explore the efficacy of the drug Amantadine for the treatment of freezing of gait in patients with Parkinson's Disease. The investigators hypothesize that amantadine is useful for management of freezing of gait in subjects with Parkinson's Disease.
