Filter by:The primary purpose of this study is to attempt to replicate and extend promising pilot findings regarding the cognitive benefits of in-home neuro-exergaming with iPACES (interactive Physical and Cognitive Exercise System v3) for persons with mild cognitive impairment (MCI), to evaluate effects for persons with Parkinson's Disease (PD). Participants will include persons with PD, and potentially, also their co-residing partner, who will exercise at home or accessible location, 3-5 times per week for at least 6 months, with follow-up one month after the main intervention. All participation is "remote" (completed at home, or location of choice), utilizing either one's own equipment ("bring-your-own-devices" BYODs: pedaler, phone/tablet, smart-watch) or some equipment which may be supplied by the grant-funded study and shipped directly to the home; all study measures are completed remotely (e.g., via phone app, website, biometric device, videoconference, email, snail mail, etc.).
Parkinson's disease is the second most common neurodegenerative disease after Alzheimer's disease. It is mostly characterized by the presence of motor difficulties. However, it can also be accompanied by cognitive disorders which have an equally significant impact on the quality of life of patients and which are not relieved by any treatment. Among the functions affected by Parkinson's disease, inhibition is an essential process for adapting our behaviors in daily life. Inhibition allows us to stop an action that is no longer required or appropriate to the situation in which we find ourselves in. For example, it comes into play when we have to stop at a "stop" sign while driving. Recent studies suggest that it could be possible to improve the functioning of these processes by using non-invasive brain stimulation tools. Transcranial alternating current electrical stimulation has thus showed promising results in improving functions such as working memory. This technique is completely painless and non-invasive and consists in applying an electric current of very low intensity (barely perceptible) at the level of the scalp, using electrodes. The investigators are conducting a study to test whether transcranial alternating current electrical stimulation could improve the functioning of the inhibition process which is altered in patients. For this, the investigators will measure this process using a task performed on a computer (the Stop Signal Reaction Time Task), as well as brain activity using a method called "electroencephalography", before and after stimulation. For this study, the investigators will include 50 patients and 40 healthy participants to investigate the effect of the stimulation on inhibition.
A cross-sectional study (part 1) aims to investigate the influence of fatigue on the MI ability in PD compared to healthy controls. A randomized controlled trial (part 2) aims to compare the effect of fNIRS-based NFB-MI on balance and gait performance versus MI only in people with PD.
The aim of the study is to compare the effects of 2 different dosages and modalities of motor-cognitive rehabilitation in Parkinson's disease with postural instability and gait disorders (PD-PIGD) on clinical features, neuroimaging and blood-based biomarkers at short-term (2 months) and long-term (7 months) follow-up. Fifty subjects with PD-PIGD will be randomized in 2 training groups: DUAL-TASK+AOT-MI and the DUAL-TASK groups. The DUAL-TASK+AOT-MI group will perform a dual-task gait/balance training consisting of action observation training (AOT) and motor imagery (MI) combined with practicing the observed-imagined exercises; DUAL-TASK group will perform the same exercises combined with watching landscape videos. The training will last 6 weeks, 3 times/week, 1 hour per session. Before and after training (W6), all the patients will undergo neurological, gait/balance, cognitive/behavioral, magnetic resonance imaging (MRI) and serum biomarkers evaluations. Neurological, gait/balance, cognitive/behavioral assessments and serum biomarkers will be also repeated at the 14-week follow-up (W14) to assess maintenance of results. Patients of both DUAL-TASK+AOT-MI and DUAL-TASK groups will be further randomized to repeat the training (6 weeks, 3 times/week, 1 hour each session) starting at W14 (DUAL-TASK+AOT-MI_DOUBLE and DUAL-TASK_DOUBLE groups). After six weeks (W20) all the subjects repeating the training will be evaluated (neurological, gait/balance, cognitive/behavioral assessments). At 28-week follow-up (W28), the whole sample of patients will be assessed with neurological, gait/balance, cognitive/behavioral, MRI and serum biomarkers evaluations. All MRI scans will be acquired at least 12 hours after last dopaminergic therapy administration to mitigate the pharmacological effects on neural activity. Twenty age- and sex-matched healthy controls will be recruited to perform gait/balance and cognitive/behavioral assessments, blood sample and brain MRI acquisition at baseline. The secondary aims of the study are to define the neuroimaging and blood-based biomarkers of PD-PIGD patients presenting different clinical features (e.g. presence of mild cognitive impairment, freezing of gait, falls and mood disturbances) and to evaluate the role of blood-based and neuroimaging biomarkers, together with clinical characteristics, in predicting the response to different dosages of rehabilitation in PD-PIGD throughout the development of a machine-learning algorithm.
TARGET-NEURO is an observational research study to conduct a comprehensive review of outcomes for patients living with chronic neurological diseases: Alzheimer's disease and related dementia (ADRD), mild cognitive impairment (MCI), Parkinson's disease (PD), and multiple sclerosis (MS).
This is a Phase I, double-blind, randomised, two-part, single-ascending dose (Part 1) and multiple-ascending dose (Part 2) study of NM-101 in healthy males and healthy females of non-childbearing potential
Introduction Bradykinesia (i.e., slow movements) is one of the most prominent symptoms of Parkinson's disease (PD) and has a negative impact on quality of life. Rhythmic auditory stimulation (RAS), a widely used and promising treatment technique, has been shown to effectively improve gait speed in PD patients. However, only few studies have explored effects and neural mechanisms of RAS on upper-limb movements. We will conduct two studies to investigate effects and mechanisms of RAS on upper-limb movements in PD patients. The purpose of this study is to examine effects and neural mechanisms of upper-limb movement training involving RAS in PD patients. Methods This study will recruit patients with PD and healthy controls. This study will randomly assign PD patients into two groups: the PD-RAS group and the PD-noRAS group, and healthy controls into the HC-RAS group and the HC-noRAS group. A 7-day upper-limb training involving RAS (for the PD-RAS group and the HC-RAS group) or without RAS (for the PD-noRAS group and the HC-noRAS group) will be provided. EEG and behavioral assessments will be conducted before and after the first day of training, and after the seven-day training program. Two-way repeated measures analysis of variance will be performed to investigate the group and time effects on upper-limb function and neural activity. Study significance The training program will serve as a reference for clinical practitioners who are interested in using RAS in clinical training for PD patients.
This is a UK only clinical trial in patients with Parkinson's disease (PD) of a drug called ambroxol hydrochloride, which is an already licensed drug for the treatment of respiratory conditions (such as a common cold) in many European countries. The aim of this trial is to find out whether ambroxol hydrochloride can slow down the progression of Parkinson's disease and to evaluate it's safety and tolerability.
The goal of this study is to estimate the cost of disease and falls among people with Parkinson's disease in Hong Kong . There will be no intervention delivered to the participants. The healthcare cost of 12 months will be recorded using self-report and and the Hospital Authority Clinical Management System.
The genetic complexity and heterogeneity of the sporadic forms of Parkinson's disease (PD) are posing a formidable challenge to disentangle their direct molecular causes. To advance this research, we plan to coordinate our local biorepositories of PD biological specimens creating a standardized and integrated national resource. In this framework, we plan to collect more samples from additional sporadic PD cases and to extend the sampling to patients with REM sleep behavior disease. We plan a large campaign of whole genome sequencing including about 200 patients to identify rare genomic variants plausibly associated with these diseases. In addition, we will standardize the generation and quality control of iPSC lines to make available to the scientific community. Finally, we will combine iPSC technology and gene editing to functionally assess the relative impact of rare variants in coding regions inherited together as a polygenic trait previously identified in selected sporadic PD cases
