Active clinical trials for "Parkinson Disease"

Inherent with intricate allocation of brain resource and attention shift, postural-suprapostural task is defined as postural control takes place while the other concurrent task is being performed. Recent studies have indicated that attentional focusing alters attention allocation in the brain as well as motor performance of a postural-suprapostural task. Also, most studies have demonstrated benefits of inducing an external focus relative to internal focus for motor performance. However, postural difficulty might be a critical factor for choosing an appropriate focusing strategy, and the strategy used in a particular difficulty level do not always generalize to other difficulty levels. Besides, despite a lot of studies have been done, current findings are confined to behavioral observations in young healthy adults for lacking direct neural evidence. With the uses of H-reflex, event-related potential and behavioral measures, the purpose of the 3-year research project is to investigate the differences in performance quality and intrinsic neural mechanisms of a postural-suprapostural task for older adults and patients with Parkinson's disease, by adopting external and internal strategies for suprapostural task under different posture difficulties. In the first year, the investigators will characterize suprapostural focusing effect on reciprocity of a postural-suprapostural task, with a special focus on modulation of motoneuron excitability in sitting and standing posture for healthy young and older adults using H-reflex technique. In the second year, the adaptive selection of suprapostural focusing strategy will be investigated for patients with Parkinson's disease by varying the standing surface (stable/unstable surface). In the third year, the investigators will investigate suprapostural focusing effect on brain resource allocation for patients with Parkinson's disease, in light of event-related potential and movement-related potential. The present project is expected to have significant contributions not only to gain a better insight to neural correlates of concurrent postural and motor suprapostural tasks with internal/external focusing strategy under different posture difficulty, but to optimize treatment strategy for older adults and patients with Parkinson's disease with balance or multi-tasking disturbances.

This two-part study will evaluate how safe LY3154207 is and the effects it has on the body. Part A will include healthy participants. Each participant will receive daily doses of LY3154207 or placebo for 14 days. Part A will last approximately 4 weeks including a 17 day stay in the clinical research unit (CRU) and follow-up. Part B is contingent on the results of Part A. Part B will include participants with Parkinson's disease. Each participant will receive daily doses of LY3154207 or placebo for 14 days. Part B will last approximately 4 weeks including a 17 day stay in the CRU and follow-up. Both Part A and Part B will require screening within 30 days prior to the start of the study.

Parkinson's disease (PD) is a common neurodegenerative disorder affecting 1-2% of the population over 65 years-old. In addition to the motor impairment characterized by resting tremor, bradykinesia, rigidity and postural instability, patients suffer with non-motor symptoms such as dysautonomia syndrome, sleep disturbances, depressive disorders, delusional disorders and cognitive disorders. Research and management of these non-motor symptoms is essential because these can be disabling and have a negative impact on the quality of life of patients. Among cognitive functions, social cognition is defined as the aspect that is dedicated to process social information for adaptive functioning. More specifically, it refers to an intricate set of higher-order neuropsychological domains that allow for adaptive behaviors in response to others. Four dimensions are usually included in this construct: theory of mind (ToM), emotion processing, social perception and social knowledge, and attributional style. Recently, different categories of social cognition have been studied in patients suffering from PD, such as the ToM or the recognition of facial emotions. Other aspects of social cognition that seem relevant in this population are still poorly studied; the attributional style is a cognitive bias defined as "the way we explain the causes of the positive or negative events that occur". Indeed, different causes can be attributed to an event, and this attribution is shared between oneself, others and other factors related to the situation. People with attribution bias may mistakenly attribute to one cause all the situations. For example, when an individual blame the others for an event, he may develop a feeling of hostility that may lead to maladaptive behavior such as aggression and thus affect his social functioning. The impact of PD treatments, particularly deep brain stimulation (DBS), on the ToM has been studied, showing a deficit after stimulation. No study has assessed the impact of therapeutics on the attributional style of PD patients. In this context, it seems relevant to evaluate the effect of deep brain stimulation on the attributional style in this population.

The principal aim of this study is to obtain safety and tolerability data when PXT002331 is administered orally as single and multiple doses to healthy subjects.

This is a phase II feasibility, safety, tolerability and preliminary efficacy study of an e-Health application versus in-person nutritional counseling to maintain or increase weight in patients with neurodegenerative diseases including amyotrophic lateral sclerosis (ALS), Parkinson's Disease (PD) and Huntington's disease (HD). Primary Objectives include the feasibility, safety, tolerability and efficacy of an e-Health application to maintain or increase body weight compared to in-person nutritional counseling. Secondary Objectives are to measure the number of calories required to maintain or increase body weight in neurodegenerative diseases at all stages of the disease. Tertiary Objectives are to test the effects of an e-Health application compared to in-person nutritional counseling on disease progression using the ALSFRS-R, UHDRS or UDysRS, on survival, and on quality of life using the PROMIS SF v1.1 scale.

The investigators will investigate the effects of an 8-week resistant starch (RS) supplementation (5 g twice a day) in patients with Parkinson Disease and matched controls on: symptoms of constipation (assessed by clinical scores); fecal short chain fatty acid concentrations (measured by chromatography); gut microbiota composition.

Our study aims to compare the effects of a standard care plan to one using adapted physical activity in patients with Parkinson Disease. Using actigraphy as an evaluation measure will allow the collection of quantitative and objective data related to activity in contrast to questionnaires which are more subjective and dependent on self-representation. In addition, the evaluation of the caregiver's actigraphy and hardship (Zarit scale) will provide interesting data from this population.

The current study adresses the effect of two different computer-based cognitive trianing programmes on attention and executive functions in patients with Parkinson's disease.

People with central nervous system disorders such as spinal cord injury, stroke, cerebral palsy, Parkinson's disease, multiple sclerosis, etc… often have impaired lower extremity function that limits activities of daily life and independence. Different body-weight support systems have been developed to facilitate the rehabilitation process by compensating for the user's residual abilities. However, studies on weight-supported gait training on a treadmill have failed to show superiority over conventional rehabilitation programs for spinal cord injury and stroke. A recent study by the group around Grégoire Courtine showed that body-weight support systems that provide assistance only in the vertical direction disrupt the production of gait and balance, suggesting that current practices may even be detrimental for relearning to walk. For the past year, the Clinique Romande de Réadaptation (CRR) worked together with the G-Lab at EPFL and G-Therapeutics on a new robot platform specifically developed to provide adjustable trunk support along four independent degrees of freedom (LEAP). The investigators were able to draw on their long-term experience, which consists of different body weight support training systems for stroke and spinal cord injury. This knowledge, combined with the input of our therapists and physicians and the specific requirements for people with neurological/musculoskeletal disorders, has resulted in a design that can provide adjustable bodyweight support during over-ground locomotion, treadmill, stairs training, standing up and sitting down and for support during the training of activities of daily living. The scope of this study is to examine how well the robot can be used for rehabilitation therapy in everyday clinical practice. This includes, among other things, technical aspects such as the handling of the hardware, the adaptability of the robot to the patient, and the safety during operation (such as the fall prevention). Various patient-specific aspects will also be evaluated e.g. comfort, positioning, or motivation of the patient. This study also aims to evaluate the software with the various support modes, operating options, and the user interface of the LEAP.

The purpose of this study is to determine the feasibility and tolerability of golf instruction for participants with moderate to advanced Parkinson's disease (PD). Other forms of exercise have been shown to be beneficial for PD. Golf is a low impact sport that utilizes balance and strength. Currently, there are no data looking at the effects of golf on PD. This pilot study aims to test the effects of golf in the PD patient population, particularly its effect on balance. In this study, we will be comparing group golf instruction to group Tai Chi lessons (the gold standard balance exercise for patients with PD).
