The investigators propose a gene therapy strategy for Parkinson's disease - a chemogenetic inhibition technique to intervene in the abnormal activity of the subthalamic nucleus in Parkinson's patients. The investigators design and construct a therapeutic injection agent called STP-001, through an efficient adeno-associated virus capsid (AAV), a neuronal promoter (hSyn), and a chemogenetic effector element (hM4Di). Then, the drug was accurately injected into the bilateral subthalamic nuclei through stereotactic surgery. After the surgery, combined with clozapine, the abnormal activity of the subthalamic nucleus was precisely intervened to improve the core motor symptoms of Parkinson's disease.

The purpose of the present research is to examine the effectiveness of a non-invasive, vibrotactile stimulation protocol, known as coordinated reset (CR), for the alleviation of motor symptoms in patients with Parkinson's disease (PD). PD patients exhibit rigidity, slowness (bradykinesia) and poverty (akinesia) of movement as well as other symptoms. Treatment for PD is either pharmacological (first line) or invasive deep brain stimulation. The non-invasive, vibrotactile stimulation approach uses a novel stimulation pattern to disrupt the pathophysiological mechanism that is responsible for PD symptoms and thus restore motor function.

This is an observational study in which data are collected and studied from Parkinson's disease patients who have movement symptoms despite taking standard Parkinson's medications. In observational studies, observations are made without any changes to the participant's healthcare or treatment plan. No investigational product will be administered in this study, as participants will be treated with the standard of care that medical experts currently consider most appropriate. Parkinson's disease (PD) is a condition that affects the brain and causes problems with movement and other body functions. The symptoms of Parkinson's disease can worsen over time. People with Parkinson's disease may experience shaking (tremor), slow movements, stiff muscles, trouble walking, and problems with balance. They can also have other symptoms, such as difficulty thinking clearly, changes in mood, or difficulty sleeping. Parkinson's disease mostly affects older adults, but it can happen to younger people too. There is no cure, but treatments can help manage the symptoms and improve quality of life. While doctors and researchers know that Parkinson's disease affects people in different ways and can worsen over time, there are still many things they don't fully understand-especially for people who experience movement symptoms despite taking their usual Parkinson's medicines. Earlier studies did not follow these patients long enough or collect all the important information needed. This study is being done to fill those gaps. The main purpose of this study is to better understand how Parkinson's disease changes over time in patients who experience movement symptoms while taking standard oral Parkinson's medications, what challenges patients and their care partners face, and how their treatments are working in real life. To do this, researchers will collect data on: * Sociodemographics (e.g. age, gender, race/ethnicity, insurance provider). * Medical history and vital signs (e.g. comorbidities, family history of Parkinson's, height, weight, blood pressure). * Medications and treatments (e.g. Parkinson's and non-Parkinson's medications and other treatments, rehabilitation therapy sessions, use of mobility assistance devices). * Movement symptoms (e.g. tremor, slow movement, balance). * Non-movement symptoms (e.g. cognition, mood, sleep, activities of daily living). * Molecular data (e.g. genetics, α-synuclein). * Burden of care (e.g. economic cost). Data will come from questionnaires or rating scales conducted by the doctor with the patient during study visits, diaries and logs completed by the patient, medical records, health insurance claims records, blood samples and skin biopsies, a digital device that records movement/non-movement symptoms, and questionnaires completed by the care partner. Data will be collected from December 2025 to December 2032. Each participant may be followed for up to 5 years.

Specific aims for the proposed study: a) to develop novel sensitive measures that can provide an early identification of those SCD and MCI individuals harboring AD pathology that are at high risk of cognitive worsening over time; b) to track pre-motor stages in Parkinson's disease and trials that enable active digital functional biomarkers; c) to track disease progression during pre-dementia and pre-motor stages in clinical practice and trials with measures that enable to capture subtle changes.
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
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.
NCT03808675
Parkinson's disease (PD) is an incurable brain illness that afflicts more than one million Americans, including many aging Veterans. PD places an unbearable burden on the individual due to progressive impairment of movement and mental function. As a result, patients lose critical abilities such as driving and can become isolated. Although drugs and surgery help movement problems, their benefits are temporary and may cause side effects. Drugs provide limited and temporary benefit for cognition and do not prevent dementia. Animal and preliminary human studies on aerobic exercise show promising results in helping a broad spectrum of symptoms. However, due to limited and inconsistent research results, the long term effects of aerobic exercise on brain health and clinical features in PD is unknown. The investigators will conduct a clinical trial to test the long term effects of aerobic exercise on the brain tissue, movement, mental functions, and driving in PD. If effective, aerobic exercise can be implemented immediately as a low cost, easily accessible treatment in PD.
