NCT07485218
With our study, the investigators aim to assess the impact of the fatigue experienced during daily life activities (tiredness) and whether there is a relationship with muscle fatigue during an exercise task. The results of this study may be used to improve the assessment of fatigue in older adults and enhance clinical management. 1. General information An increase in fatigue is considered one of the main causes of reduced quality of life in older adults and in people suffering from chronic diseases. However, the investigators still know little about the mechanisms underlying fatigue in older adults, mainly because most of the available tools were developed to assess this symptom in younger populations with specific diseases, without proper adjustments for physical activity or age. In 2015, the Pittsburgh Fatigability Scale (PFS) was developed as a self-administered questionnaire to assess both physical and mental fatigue in older adults. The PFS consists of 10 questions describing activities of varying duration and intensity. The other scale the investigators will ask participants to complete is called the Fatigue Severity Scale (FSS): a 9-item questionnaire that evaluates fatigue intensity in various situations over the past week. Participants' fatigue will also be assessed during two motor tasks simulating daily activities: a handgrip test and a seated leg exercise mimicking walking. If participants decide to take part in our research project, participants will complete the PFS and FSS questionnaires once (5-10 minutes) and perform two brief motor exercises to determine the onset and progression of muscle fatigue. The exercises will last about 20 minutes, with an additional 10 minutes for preparation. Each contraction will last a maximum of 2 minutes. The project will last 12 months (Swiss section) and will be conducted at \[(1) the nursing homes of the Multistruttura di Bellinzona, the Fondazione Parco San Rocco facilities in Morbio Inferiore and Coldrerio, and the Opera Charitas nursing home in Sonvico\] (period: December 2024 - May 2025); and (2) at the \[San Raffaele University Research Institute\] in Milan, Italy, where 40 older adults with Parkinson's disease will participate (September 2026 - March 2027). This research project is conducted in accordance with Swiss legislation and current international ethical guidelines. It has been reviewed and approved by the Ethics Committee of the Canton of Ticino. 2. Study procedure The testing session will last a maximum of 30 minutes and will include the following steps: Discussion of the study procedures. Verification of appropriate leg clothing. The exercise can be performed either by wearing shorts or by rolling up long trousers to expose the upper half of the thigh. Review of the completed Pittsburgh Fatigability Scale (PFS) questionnaire and completion of the Fatigue Severity Scale (FSS), both available in Italian. Performance of two motor exercises (a surrogate walking test and a handgrip test). 1. First, participants will be instructed on how to perform the surrogate walking test, which evaluates leg muscle fatigue. During the exercise, participants will push with their legs and foot on a movable platform that slides along rails within the device. The sliding motion is resisted by elastic bands that stretch and shorten as participants push. The exercise will be repeated for several cycles until participants are told to stop. To measure muscle fatigue, surface electrodes (non-invasive) will be placed on the skin over two thigh muscles. 2. After a 5-minute rest, participants will be asked to perform the handgrip test with participants' right hand (see Figure 3). The maximal handgrip test will be performed while seated, with participants' forearm resting on a table. The test will be repeated several times until participants are instructed to stop.

NCT07310264
This is a first-in-human (FIH) study of orally administered VT-5006 (also known as AX-5006) in healthy adult volunteers (HVs) and adult participants with Parkinson's disease (PD). The goal of this clinical trial is to learn if VT-5006 is safe and tolerable in healthy volunteers and in participants with PD. It has three Parts (A, B, and C). Part A: Healthy volunteers aged 18-54 will attend a screening visit, take a single dose of VT-5006 or matching placebo after an overnight fast, stay in the clinic for three nights, and complete a follow-up visit. One group of participants in Part A will be asked to return to the clinic after approximately two weeks, take a single dose of VT-5006 or matching placebo after consuming a high-fat meal and stay in the clinic for another three nights. Part B: Healthy volunteers aged 18-54 will attend a screening visit, take one dose of VT-5006 or matching placebo each day for seven days after fasting overnight, stay in the clinic for 10 nights, and complete a follow up visit. Part C: Participants with PD aged 40-80 will attend a screening visit, take one dose of VT-5006 (high dose), VT-5006 (low dose), or matching placebo each day for 28 days, complete two overnight stays in the clinic, attend three clinic visits, one phone call and a follow up visit.
NCT02119611
Background: \- In deep brain stimulation (DBS), a device called a neurostimulator is placed in the chest. It is attached to wires in parts of the brain that affect movement. DBS might help people with movement disorders like Parkinson s disease (PD), dystonia, and essential tremor (ET). Objective: \- To provide DBS treatment to people with some movement disorders. Eligibility: \- Adults 18 years and older with PD, ET, or certain forms of dystonia. Design: * Participants will be screened with medical history and physical exam. They will have blood and urine tests and: * MRI brain scan. The participant will lie on a table that slides in and out of a metal cylinder with a magnetic field. They will be in the scanner about 60 minutes. They will get earplugs for the loud noises. During part of the MRI, a needle will guide a thin plastic tube into an arm vein and a dye will be injected. * Electrocardiogram. Metal disks or sticky pads will be placed on the chest, arms, and legs. They record heart activity. * Chest X-ray. * Tests of memory, attention, concentration, thinking, and movement. * Eligible participants will have DBS surgery. The surgery and hospital care afterward are NOT part of this protocol. * Study doctors will see participants 3 4 weeks after surgery to turn on the neurostimulator. * Participants will return every month for 3 months, then every 3 months during the first year, and every 6 months during the second year. Each time, participants will be examined and answer questions. DBS placement will be evaluated with MRI. The neurostimulator will be programmed.

NCT06821230
The proposed two-arm randomized waitlist-controlled trial will use a mixed-methods design to investigate the effects of dyadic mindfulness on physio-psycho-spiritual outcomes in people with Parkinson's Disease (PwPD) and their family caregivers. One hundred Chinese patient-caregiver dyads will be randomized to receive eight weekly 90-minute dyadic mindfulness sessions or usual care. Outcome measures include negative emotions (primary outcome), patient-caregiver relationship, mindfulness, HRQOL, gut microbiome, PD-related symptoms, and caregiving burden. An actor-partner interdependence model will be used to explore the interactions of treatment effects within the dyads. The dyads will be assessed at baseline(T0), post-intervention(T1), and 4-months post-intervention(T2). The investigators will also invite 25 dyads to attend in-depth interviews exploring their experiences, perceived changes, and factors attributable to the effectiveness/ineffectiveness of the intervention. Generalized linear mixed-effects (GLME) with intention-to-treat analysis will be used to compare the changes in outcomes over time within and between the two arms. The findings will be triangulated to provide a comprehensive evaluation of the intervention's effectiveness. This study will generate rigorous scientific evidence to inform the application of dyadic mindfulness as a public health practice preventing the progression of psychological distress in PwPD and caregivers to clinically severe levels. Its self-help nature also enriches the primary care for this clinical cohort.
NCT03526991
Parkinson Disease (PD) patients experience a variety of motor issues such as walking difficulties, loss of balance, and freezing while walking, which impacts their quality of life. Some symptoms, like freezing of gait (FOG), do not respond to medications typically used to treat PD. Current surgical procedures used to alleviate PD symptoms also do not always improve FOG. Since many traditional therapies have failed for the treatment of FOG, researchers have proposed the use of newer treatments. Recent research in animal models and clinical human data using SCS has produced promising results, specifically showing improvement in FOG with the use of SCS in patients with PD. The purpose of this study is to evaluate the effectiveness of spinal cord stimulation (SCS) for the management of freezing of gait (FOG) that does not respond to conventional treatments in subjects with Parkinson's disease (PD). The investigators hypothesize that SCS significantly decreases FOG episodes in patients with PD. 1. Assess the safety, tolerability and preliminary evidence of effectiveness of upper thoracic spinal cord stimulation for freezing of gait in Parkinson's (PD) patients. 2. Explore the effects of two SCS programming paradigms on motor, nonmotor and quality of life measures in PD patients with freezing of gait.
NCT01019343
Background: * Previous studies have given researchers information on how the brain controls movement, how people learn to make fine, skilled movements, and why some people have movement disorders. However, further research is needed to learn more about the causes of most movement disorders, such as Parkinson's disease. * By using small, specialized studies to evaluate people with movement disorders and compare them with healthy volunteers, researchers hope to learn more about the changes in the brain and possible causes of movement disorders. Objectives: * To better understand how the brain controls movement. * To learn more about movement disorders. * To train movement disorder specialists. Eligibility: * Individuals 18 years of age or older who have had a movement disorder diagnosed by a neurologist and are able to participate based on the specific requirements of the small study. * Healthy volunteers 18 years of age or older. Design: * Participants will have a screening visit with medical history, physical examination, and questionnaire to determine eligibility. Eligible participants will give consent to participate in up to seven additional outpatient visits for study procedures. The number of sessions and the procedures needed for participation depend on specific symptoms. * Participants must avoid drinking alcohol or caffeinated drinks (sodas, coffee, and tea) for at least 2 days (48 hours) before each session. * Potential studies may include magnetic resonance imaging (MRI) scans, functional MRI scans, electroencephalography, magnetoencephalography, transcranial magnetic stimulation, nerve and sensory stimulation, or movement and mental tasks during any of the above procedures. * This study does not provide treatment for movement disorders. Participants will not have to stop any treatment in order to participate.
NCT07322887
The main goal of the study is to investigate how well the new drug SUL-238 works in Parkinson's Disease (PD). This is done by means of an MRS scan. An MRS scan is similar to a regular MRI scan. It will also learn about the safety of new drug SUL-238. The main questions it aims to answer are: * Does new drug SUL-238 improve the mitochondrial function in patients with Parkinson's Disease (PD)? * What medical problems do participants have when taking new drug SUL-238? Researchers will compare new drug SUL-238 to a placebo (a look-alike substance that contains no drug) to see if SUL-238 works to improve mitochondrial function in patients with PD. Participants will: * Take new drug SUL-238 or a placebo every day for 28 days * Visit the clinic once every 2 weeks for checkups and tests during the treatment period and finally 28 days after the last dose of SUL-238 * Keep a diary of their symptoms and the number of times they use oral new drug SUL-238
NCT06671626
Humans can rapidly regulate actions according to evolving environmental demands, however, impairments of action regulation have been identified across a number of neurological disorders including Parkinson's Disease (PD). A key component of action regulation is action inhibition that occurs when stopping unwanted or inappropriate actions. There is mounting evidence that action inhibition also plays a critical part in selecting between competing alternative actions and switching to new actions in response to environmental changes. The investigators hypothesize that stop circuitry (involving frontal-subthalamic nucleus (STN) pathways) are involved in inhibiting unselected actions during action selection with competing alternatives (in the absence of overt stopping) and that switching motor plans also engages stopping circuitry (involving prefrontal-STN pathways) for cancelling the ongoing action, before changing to new one. The overall goal is to delineate the neural circuitry underlying a broad array of action regulation functions that involve inhibitory control, how these functions interrelate, and how they are implemented within brain networks. In this research, the investigator will take advantage of the unique opportunity provided by awake deep brain stimulation surgery to learn more about how the brain functions in a diseased state and how deep brain stimulation changes these networks to make movement more normal. The investigator will simultaneously assess cortical and subcortical electrophysiology in relation to clinical symptoms and behavioral measures and in response to deep brain stimulation in patients undergoing Deep Brain Stimulation (DBS) implantation surgery.

NCT06692920
When a patient gets DBS surgery, the neurosurgeon makes a hole in the skull through which they can put the DBS lead down in deep parts of the brain that help control movement. For this study, research participants will also have an ECoG strip put through the same hole (no extra holes are being made for research purposes). The ECoG strip is a little less than half an inch wide, and a little more than 2.5 inches long. It is very, very thin; it is a thin plastic film with flat metal sensors that can record the electrical activity in the brain. The ECoG strips are FDA approved. The neurosurgeon will slide the ECoG strip under the skull but on top of the brain, over another area of the brain that helps control hand/arm movement (motor cortex), so that the study team can record the activity there. The study team will record brain activity from the DBS lead and the ECoG strip simultaneously to try to understand how the brain communicates and sends information. The study team will check that the ECoG strip is in the right place by delivering a very small electrical pulse to the wrist. If the ECoG strip is in the correct location, this electrical pulse will show up on the brain activity being recorded by the sensors in the ECoG strip. Fluoroscopy (i.e. X-ray images that can be taken quickly) will also be done at the end of the surgery to help confirm the location of the ECoG strip. During fluoroscopy, an X-ray beam is used to track a contrast agent ("X-ray dye") through the body, so that the body can be seen in detail. This involves some radiation exposure for the participant, so this is described in the consent form. Patients who want to sign up for the study will not be allowed to do so if they have had other radiation exposures within the past year that would go over a safe limit when added to the amount of radiation expected from the fluoroscopy for this study.
NCT04246437
Alpha-synucleinopathies refer to age-related neurodegenerative and dementing disorders, characterized by the accumulation of alpha-synuclein in neurons and/or glia. The anatomical location of alpha-synuclein inclusions (Lewy Bodies) and the pattern of progressive neuronal death (e.g. caudal to rostral brainstem) give rise to distinct neurological phenotypes, including Parkinson's disease (PD), Multiple System Atrophy (MSA), Dementia with Lewy Bodies (DLB). Common to these disorders are the involvement of the central and peripheral autonomic nervous system, where Pure Autonomic Failure (PAF) is thought (a) to be restricted to the peripheral autonomic system, and (b) a clinical risk factor for the development of a central synucleinopathy, and (c) an ideal model to assess biomarkers that predict phenoconversion to PD, MSA, or DLB. Such biomarkers would aid in clinical trial inclusion criteria to ensure assessments of disease- modifying strategies to, delay, or halt, the neurodegenerative process. One of these biomarkers may be related to the neurotransmitter dopamine (DA) and related changes in the substantia nigra (SN) and brainstem. \[18F\]F-DOPA is a radiolabeled substrate for aromatic amino acid decarboxylase (AAADC), an enzyme involved in the production of dopamine. Use of this radiolabeled substrate in positron emission tomography (PET) may provide insight to changes in monoamine production and how they relate to specific phenoconversions in PAF patients. Overall, this study aims to identify changes in dopamine production in key regions including the SN, locus coeruleus, and brainstem to distinguish between patients with PD, MSA, and DLB, which may provide vital information to predict conversion from peripheral to central nervous system disease.
NCT04127578
Study J3Z-MC-OJAA is a Phase 1/2a, multicenter, open-label, ascending dose, first in-human study that will evaluate the safety of intracisternal LY3884961 administration in patients with moderate to severe Parkinson's disease with at least 1 pathogenic GBA1 mutation. Two dose level cohorts of LY3884961 are planned (Dose Level 1 and Dose Level 2). The duration of the study is 5 years. During the first year, patients will be evaluated for the effect of LY3884961 on safety, tolerability, immunogenicity, biomarkers, and clinical efficacy measures. Patients will continue to be followed for an additional 4 years to continue to monitor safety as well as selected biomarker and efficacy measures.
NCT06113640
Parkinson's disease (PD) is the second most common neurodegenerative disorder after Alzheimer's disease (AD). Clinical manifestations of PD can vary, but a formal diagnosis relies on the presence of bradykinesia with rigidity and/or rest tremor according to Movement Disorder Society (MDS) criteria for PD. Non-motor symptoms, such as hyposmia, constipation, depression, and rapid eye movement (REM) sleep behavior disorder, are common and can in many cases manifest before classical motor symptoms. In later years, more emphasis has been put on non-motor symptoms, especially in the early stages of PD and which is evident in the proposed prodromal PD criterion by MDS.

NCT06543810
Parkinson's improvement Activated by Hula Understanding (PAHU), a pilot study, will evaluate the feasibility of hula program on patients with Parkinson's disease (PD). Hula combines several aspects-moderate physical activity, cardiovascular risk reduction, social support opportunities, and other stress-reducing qualities that have potential to prevent further neurodegeneration, improve balance and mobility, help non-motor symptoms and quality of life of PD patients in a sustainable and relatable fashion. The investigators will create a hula program specifically to the needs of patients with PD with mobility difficulty as a non-pharmacological intervention and conduct a pilot study to test the feasibility of such program. The investigators will learn from leaders of the Dance for PD (NYC), an internationally acclaimed program offering a range of dance classes for PD patients), as well as other key informants. The investigators will create once a week hula program for 3 months for PD patients and assess the feasibility of such program. Participants will undergo motor testing before and after the hula program, and will be interviewed for their feedback.
