The goal of this Phase 2 clinical trial is to investigate the efficacy and safety of NEU-411 in men and women aged 50-80 years with early Parkinson's Disease (PD) who have predicted elevations in the activity of the "leucine-rich repeat kinase 2" ("LRRK2" for short) pathway based on their genetic profile. A DNA test will be used to identify the "LRRK2-driven" population with predicted elevation in the LRRK2 pathway. Participants will: • Take NEU-411 or placebo every day for 52 weeks
This study will examine the effects of lithium 20mg/day compared to placebo on MRI and blood-based biomarkers among 20 early-stage Parkinson's disease patients.
The primary aim of the study will be to examine Social Cognitive Theory (SCT) correlates, of physical activity (PA) participation and health-related quality of life (HRQoL) in Parkinson's disease participants.
Parkinson's disease affects all the nerve cells in the body, including the ones in the gut. The gut contains its own nervous system, the enteric nervous system, and can be thought of as a "second brain". This second brain can reflect what is going on in the actual brain. This study is being done to look for biomarkers, or early indicators of developing Parkinson's disease, in the microbiome and in the gut tissue taken during routine screening colonoscopy. People aged 45 and over who are due for their routine screening colonoscopy are eligible to participate.
The purpose of this project is to increase our understanding of the early state and temporal evolution of neuroplastic changes in the cortex and subthalamic nucleus (STN) of people with PD, and the relationship of these changes to the emergence and expression of PD motor and non-motor signs. Neurophysiological biomarkers derived from this work may be important for the early detection and prediction of progression of disease. They can also provide the means to assess the efficacy of interventions designed to prevent or slow disease progression.
The study aims to better understand motivation and value-based decision-making in Parkinson's patients through neurophysiology using Medtronic's Percept DBS device. By combining behavioral tasks with neural recordings, the study seeks to uncover how DBS affects motivation, particularly in relation to effort, reward, and timing.
The goal of this clinical trial is to learn about the role of noradrenergic system in the non-motor symptoms of Parkinson's disease. The main objectives it aims to answer are: 1. To explore the association between orthostatic hypertension which is low blood pressure that occurs after going from lying to standing, and several neuropsychiatric and neurocognitive nonmotor features of Parkinson's disease (PD), such as feeling tired or disinterested and depression. 2. To explore the association between central noradrenergic dysfunction, orthostatic hypertension, and nonmotor symptoms of PD by measuring hormonal response to head up tilt-table testing before and after administration of yohimbine. 3. To explore the association between central noradrenergic dysfunction, orthostatic hypertension, and nonmotor symptoms of PD by measuring participants pupils before and after administration of yohimbine Participants will be asked to come onsite for two study visits. Visit one will consist of: * Discussing and signing the Informed Consent Form * Discussing Medical History and Current Medications * Collecting Blood samples * Measuring heart rate and blood pressure * Mental health screening and neurocognitive questionnaires * Pupil test * Test to feel vibrations Visit two will consist of : * Mental Health questionnaire * IV Placement * Blood Draws * Administration of Yohimbine hydrochloride * Head up tilt table * Measuring heart rate and blood pressure * Answering questions about anxiety, mood, and fatigue using a scale * Pupil tests Visit three will be a follow-up call from the Nurse Coordinator to discuss any adverse events.
This study is designed to measure the change in patients diagnosed with Parkinson's disease (PD) before, during and after a 12 week exercise program.The focus of this study is the glymphatic system. The glymphatic system is a recentlydiscovered novel waste clearance pathway, in patients with Parkinson's Disease (PD).The glymphatic system acts as a waste-clearance system in the brain of vertebrate animals.The glymphatic system has been proposed in which new clearance pathways involving communication between paravascular spaces, interstitial fluid, and ultimately meningeal and dural lymphatic vessels exists, and we have provided evidence that this system may be dysfunctional in patients with Parkinson's disease with cognitive disorders. Early research suggest glymphatic function increases following exercise, this response is believed to clear beta-amyloid in the brain and may mediate the neurobehavioral response to exercise in PD. This study will use cognitive exams, neurological exams as well as specialized imaging to record data points and evaluate the glymphatic function after exercise.

This controlled prospective cohort study is designed to assess the feasibility and effect of twice-weekly 60 minute non-traditional guitar classes on PD patient's self-reported and measurable outcomes including upper extremity function, motor findings, quality of life, mood, and cognitive findings. 24-30 individuals with PD will be randomly assigned to an early-start and a late-start guitar instruction group. Prior to conducting a larger study, this study seeks to assess the possibility that participation in an instrumental performance activity in a group setting may improve outcomes in PD patients.
Study Purpose: Parkinson's disease leads to severally impaired motor control. The purpose of this study is to better understand and analyze the characteristics of arm muscle activity while doing some reaching tasks and of leg muscles while walking. This will allow the investigators to improve understanding of the mechanisms underlying the motor impairments in Parkinson's disease.
We hypothesize that reductions in gamma activity are a key mechanism underlying cognitive dysfunction in PD and that interventions to increase gamma activity will improve cognition.
This study plans to learn more about the brain function related to thinking problems in individuals with Parkinson's disease.
The purpose of this study is to characterize the pharmacokinetics (PK) of LY03003 following multiple escalating intramuscular injections, as compared to Neupro patch and to evaluate the safety and tolerability and preliminary efficacy of multiple ascending dose (MAD) of LY03003 following intramuscular injections.
The purpose of this study is to examine the brain changes in people with Parkinson's Disease (PD) after they get deep brain stimulation (DBS) surgery, compared with people who do not have Parkinson's Disease. Treatment of Parkinson's disease is often difficult and challenging. Deep brain stimulation is an established surgical treatment that is effective for the treatment of PD, but the details of why it helps are not known. In order to achieve maximum benefits from this treatment, it is important to understand how it changes the brain. Specifically, the investigators will study electrophysiology, which is the study of how the brain conducts electrical messages to the rest of the body. To do this, the investigators will use transcranial magnetic stimulation (TMS), which is a painless and non-invasive procedure. They will also conduct motor physiology experiments of the upper and lower limbs to collect data about skeletal muscle movement. The data from this study will help explain whether the electrical changes in the brain have any relation to the physical benefits patients with Parkinson's Disease sometimes receive from DBS surgery.
This study is designed to determine if magnetic resonance imaging (MRI) measures can be used to diagnose and monitor the progression of Parkinson's disease (PD) while distinguishing between PD and parkinsonisms \[conditions that are PD look-a-like diseases such as progressive supranuclear palsy (PSP) or multiple system atrophy (MSA)\] when combined with changes in certain proteins in body fluids that are related to iron (Fe).
In a recent study it was found that neurologist care for Parkinson's provides a 20% reduction in nursing home placement, hip fracture, and death (Willis 2011). However, as the authors recognized, the investigators don't know what it is about expert care that delivers this benefit. The Parkinson's Foundation's Quality Improvement Initiative was designed to identify the components of great care that yield great outcomes. By capturing demographics, clinical interventions and outcomes over time from multiple centers across the U.S, Canada and internationally, the best care practices from different clinics and different healthcare systems will be analyzed.
The purpose of this study is to evaluate the effect of AMPYRA on a number of symptoms in Parkinson's disease. AMPYRA is a medication approved by FDA for gait dysfunction in multiple sclerosis. There are multiple studies to suggest that persons with multiple sclerosis benefit from this medication and have major improvements in gait after taking this medication. However, this medication was never studied in Parkinson's disease. This study aims to learn about possible benefits of AMPYRA in Parkinson's disease (PD).
The intent of this clinical study is to answer the questions: 1. Is the proposed treatment safe 2. Is treatment effective in improving the disease pathology of patients with Parkinson's Disease and clinical outcomes.
The purpose of this study is to examine how genes and environment affect risk for Parkinson's disease.
A decrease or loss of the sense of smell is very common in patients with Parkinson's Disease even in the earliest stages of the disease. There have been no treatments that have been proven to improve sense of smell in patients with Parkinson's Disease. Rasagiline (brand name: Azilect) was approved by the U.S. Food and Drug Administration (FDA) on May 16th 2006 to be used by Parkinson's patients to treat the motor symptoms associated with the disease. The purpose of this study is to see if there is change in sense of smell after starting Rasagiline.
Eligible participants, who participated in the ADAGIO trial and who sign an approved informed consent form, will be enrolled into the study at their original study locations. participants who have stopped rasagiline therapy and in the opinion of the investigator will gain clinical benefit from restarting treatment can also be considered for enrollment in the Core follow-up study period. Use of any other anti-PD treatment is permitted as deemed necessary by the treating physician (according to the participants clinical status).
Parkinson's disease (PD) is the second most common neurodegenerative disease in the US, affecting nearly 1 million Americans. Up to 82% of community dwelling individuals with PD complain of sleep disturbances, typically sleep fragmentation. Despite the high prevalence of sleep problems and their impact on the life of these individuals, there has been, until recently, little research focus on the problem. This will be a multi-site, double blind, placebo-controlled, two arm, parallel group, fixed-dose trial which will last 6 weeks. Seventy patients at four sites (30 at the PI's site and a total of 40 patients at three external sites) will be equally randomized to eszopiclone or placebo. The primary hypothesis is that eszopiclone will be superior to placebo for the treatment of insomnia in patients with Parkinson's disease
This study will examine the effects of repetitive transcranial magnetic stimulation (rTMS) on Parkinson's disease symptoms. rTMS is a way of stimulating the brain that may be able to change the electrical activity of the nerve cells in the brain. It has been proposed as a treatment for brain disorders, including Parkinson's disease. In preliminary studies, some patients' symptoms improved; in some they worsened temporarily, and some showed no change. Patients between 40 and 80 years of age with moderately severe Parkinson's disease, whose main problem is slowness of movement and stiffness, may be eligible for this study. Participants will be randomly assigned to one of two treatment groups: one will receive rTMS to parts of the brain involved in controlling movement; the other will receive sham, or placebo, stimulation. Nine treatments will be given over a 4-1/2 week period. Patients will take their Parkinson's disease medications during the study, but will stop taking the medicines for 4 to 5 hours before one of the sessions. For rTMS, an insulated wire coil is placed on the scalp. A brief electrical current is passed through the coil, creating a magnetic pulse that stimulates the brain. The pulses are delivered in trains, or short bursts, lasting 1 second each. There will be 48 trains for a total of 1200 pulses per 24-minute session. The stimulation may cause muscle twitching in the scalp or face and may also cause small movements of the limbs. Just before and after each rTMS session, patients will have a neurologic examination, including an evaluation of walking. Their motor function tests will be recorded on videotape to document possible improvement and to allow physicians to rate the improvement. The physicians will not know which patients are receiving actual rTMS and which are receiving sham treatment. Ratings before the first and after the last rTMS sessions will be more detailed.
This study will use transcranial magnetic stimulation (TMS) to explore how the brain controls movement by sending messages to the spinal cord and muscles and what goes wrong with this process in disease. Activity in the motor cortex-the outer part of the brain-will be examined use TMS in patients with Parkinson's disease and in healthy volunteers. Normal volunteers and patients with Parkinson's disease (stage I to III) 21 years of age and older may be eligible for this study. All participants will have transcranial magnetic stimulation. For this procedure, an insulated wire coil is placed on the subject's scalp and a brief electrical current is passed through the coil. This creates a magnetic pulse that passes into the brain and generates very small electrical currents in the cortex, briefly disrupting the function of the brain cells in the stimulated area. This may cause muscle twitching or tingling in the face, jaw or limb. During the stimulation, participants will be asked to tense certain muscles slightly or perform other simple actions. The electrical activity of the muscle will be recorded on a computer through electrodes taped to the skin over the muscle. In most cases, the study will last less than 3 hours. Participants will also fill out questionnaires about aspects of personality and will be tested for their ability to perform certain cognitive (thinking) and movement tasks. Patients with Parkinson's disease will, in addition, be administered the Uniform Parkinson's Disease Rating Scale to measure disease severity. Patients will be requested to stop all Parkinson's disease medications 12 hours before the study. They may resume medications immediately after the study. Patients who so wish may be admitted to the hospital the day or evening before the study while they are off medications and stay there until they feel ready to leave.
