Filter by:Sleepiness is frequent in parkinsonian patients, increasing with the duration of disease. By patients with motor fluctuations, continuous dopaminergic delivery devices or deep brain stimulation are justified to improve the motor prognosis. Antiparkinsonian treatments, especially dopaminergic agonists, may worsen the sleepiness and thus affect the quality of life. The investigators aimed to monitor sleepiness in parkinsonian patients before and during treatment with continous dopaminergic delivery device or deep brain stimulation.
The objective of this study will be to identify multidisciplinary fall risk factors in persons with stage 3 idiopathic Parkinson's Disease compared to age and sex-matched healthy adults. Both the relative contribution of each independent factor, as well as the interaction between these factors, will be examined. The study will include multidisciplinary assessments, including locomotor, speech, auditory, vestibular and opthalmologic assessments.
Given the emerging evidence on LRRK2-related biomarkers, this project will focus on identifying leucocyte and urine biomarkers that are altered by the LRRK2 G2385R variant, and investigating the effects of LRRK2 kinase inhibitor (MLi-2) on these biomarkers, using immunoblotting and mass spectrometry.
This is a Phase 2b study investigating the efficacy and safety of mesdopetam as adjunct therapy on daily ON-time without troublesome dyskinesia in patients with Parkinson disease. Mesdopetam is taken for 84 days.
The hypothesis is that the differential extent of microstructural damages in the affected brain regions can be specific to the disease of interest and could reflect the clinical severity. Therefore, the investigator propose that whole brain parcellation of diffusion MRI can be used to improve diagnosis and prediction of clinical outcomes in Parkinson's Disease. 1. A regression model between clinical severity and two year clinical outcomes and diffusion properties from multiple parcellated regions will be developed. 2. Blind validation will be performed.
Freezing of gait (FOG) is a common and devastating symptom in advanced stage Parkinson's disease (PD), which contributes to falls and disability. Unfortunately, there is no effective pharmacological treatment for FOG. It is suggested that the cortex-basal ganglia circuit, especially the frontal lobe, plays an important role in the pathogenesis of FOG. Repetitive transcranial magnetic stimulation (rTMS) effects over the cortex and affects the subcortical neural circuits. Previous studies have demonstrated that rTMS can improve FOG for PD patients. In the present randomized controlled trial (RCT) study, the invastigators aim to investigate the efficiency of rTMS over different motor regions of frontal lobe. The efficacy of treatment is evaluated by the score of FOG questionnaire and FOG provoking test, and the changing of neural network shown by functional magnetic resonance imaging (FMRI). Then the effects of rTMS over different brain regions will be compared for choosing a better target. The study will provide the evidence for non-invasive neuro-modulation of Parkinson's disease with freezing of gait (PD-FOG).
Parkinson disease (PD) is considered a multisystemic neurodegenerative disorder, together with the classic motor disability, and a number of non-motor symptoms (NMS).NMS have a significant negative relation with patients' quality of life. In general, both medicinal and nonmedicinal therapies are often advised for PD patients with NMS, but robust evidences for underpinning the clinical effects are limited. Recently, the search for small preventative neurotrophic compounds that are responsible for the maintenance, survival of neurons has attracted much attention. Erinacine A, which is extracted from Hericium erinaceus is the one showed prominent beneficial effects in the central nervous system. It can increase NGF and catecholamine content in the locus coeruleus and hippocampus of rats. This markedly increases neuronal survival in different brain areas and substantially improve behavioral outcomes in various animal models. In a MPTP-induced Parkinsonism model, treatment with Hericium erinaceus mycelium reduced the loss of dopaminergic cell, eliminated neuronal apoptosis and reversed MPTP-associated motor deficits. Thus, this project intends to hold a randomized, controlled trial to assess the effect of Hericium erinaceus mycelium, which is enriched of Erinacine A, in NMS of PD. This project will enroll 80 patients with PD. Subjects will be randomly allocated into study or placebo group. Subjects will take Hericium erinaceus mycelium for 2 years (one capsule per meal per day) and their treatments for PD will not be altered.
Background: Parkinson Disease (PD) is a nervous system disorder that affects movement. Dopamine is an important neurotransmitter in the brain. As PD progresses, there is less and less dopamine in the brain. Researchers think there may be a relationship between differences in attention and dopamine in people with PD. Objective: To learn if people with PD that is worse on one side also have differences in how much attention they pay to the two sides of space on their left and right. Eligibility: English-speaking, right-handed people age 35-80 with PD. Design: Participants will be screened with medical and neurological history and exam, and medicine review. Participants will have 1 study visit. It will last 7-8 hours. They will stop taking their Parkinson medicine 12 hours before the visit. Participants will complete questionnaires. Participants will do tasks on a computer screen. They will judge the middle of lines, react to stimuli, and search and identify items that appear on the screen. Participants may have functional and structural magnetic resonance imaging (MRI). MRI uses a strong magnetic field and radio waves to take pictures of the brain. During the MRI, participants will lie on a table that slides in and out of the MRI scanner. While inside the scanner, they will look at a cross on a screen, relax, and think about nothing. Participants will undergo prism adaptation. They will sit in front of a board while their chin rests on a support. They will point to 1 of 2 dots on the board while they wear prism glasses that shift their vision to the left or right....
These caregivers are a vulnerable group due to their physical isolation and well-documented rural disparities in health care access and quality. Many rural dementia caregivers experience serious health consequences due to caregiving responsibilities that can limit their ability to maintain their caregiving role. Thus, there is a pressing need for effective, scalable, and accessible programs to support rural dementia caregivers. Online programs offer a convenient and readily translatable option for program delivery because they can be accessed by caregivers in the home and at the convenience of the user. Building Better Caregivers is an online 6-week, interactive, small-group self-management, social support, and skills-building workshop developed for caregivers of individuals with Alzheimer's disease or related dementia. The investigators will conduct a hybrid effectiveness-implementation randomized controlled trial that will enroll and randomize 640 rural dementia caregivers into two groups: the intervention (workshop) group and the attention control group. Caregivers will be recruited throughout the United States. Primary outcomes will be caregiver stress and depression symptoms. The investigators hypothesize that stress scores and depression symptoms will be significantly improved at 12 months in the intervention group versus control group. The investigators will also identify key strengths (facilitators) and weaknesses (barriers) of workshop implementation. The investigators will use the RE-AIM implementation framework and a mixed methods approach to identify implementation characteristics pertinent to both caregivers and rural community organizations. If the Building Better Caregivers workshop is proven to be effective, this research has the potential to open new research horizons, particularly on how to reach and effectively support isolated dementia caregivers in rural areas with an intervention that is scalable, even in low-resourced settings. If the workshop can achieve its goals with rural dementia caregivers, some of those most isolated, it would also be expected to be scalable in other low-resourced settings (e.g., in urban or suburban environments).
The study is an adaptation of the Long Lasting Memories (LLM) (NCT02267499) and the subsequent LLM Care (NCT02313935) projects in patients with Parkinson's Disease (PD). The study aims to examine the viability and any potential benefits of cognitive and physical training, as offered via the ICT-based (non-pharmacological) intervention of LLM Care, on people with PD. It is worth investigating whether this intervention can offer a better quality of life in patients with PD and counterbalance the often associated with the PD disease neurodegeneration. To evaluate any physical, cognitive, behavioral, and neuroplastic changes and measure the influence (affective status of participant) of the training on the pathological population, the study utilizes somatometric and neuropsychological assessments and neuroscientific (electroencephalographic, EEG-related) indices, as well as affective computing systems.
