This study will test if bemdaneprocel (the "study drug") is safe and effective in improving symptoms in participants with Parkinson's Disease. The symptoms of PD are due to a loss of cells that make a specific chemical in your brain called dopamine. The study drug is a cell therapy that contains live brain cells that produce dopamine. This study will last 5 to 8 years, and depending on randomization group between 23-32 study visits.

This is a study of oral "CVN424" at two dose levels in Parkinson's Disease (PD) patients with motor fluctuations (wearing off of PD medications). Participation will last about 14 weeks. Patients must be at least 30 and have considerable wearing off periods.

The purpose of this research is to explore the effects of participation in a pickleball community-based exercise program on function in people with Parkinson's disease (PwPD). Individuals will engage in an 8-week instructional pickleball exercise program designed specifically by Movement Disorder Specialists at the Medical University of South Carolina for PwPD. The pickleball training program involves warm-up exercises, stroke mechanics, fall safety and recovery technique training, effective movement pattern drills, game play strategies, and match play. We aim to quantify the motor function, balance, mobility, and quality of life outcomes through clinical assessments and questionnaires before and after participation in the Pick it Up Pickleball training program. This research will establish an evidence base for pickleball as a therapeutic intervention, opening the door for additional accessible and engaging exercise options for the PD community.

Deep brain stimulation (DBS) is a surgical treatment that can help improve the symptoms of Parkinson's disease (PD). However, the effectiveness of this treatment varies among patients, and physicians currently have no way to predict who will benefit the most. This study will investigate whether the types of bacteria in a person's gut can help predict their response to DBS. By analyzing patient samples, we aim to identify biomarkers that could help doctors better select candidates for this procedure, ultimately leading to more successful treatment outcomes for individuals with Parkinson's disease.

This study aims to study the natural progression of P-SYN quantification by conducting skin biopsies in patients with Parkinson's Disease (PD) and REM sleep behavior disorder (RBD). Participation will be over an 18-month period and will include skin biopsies and clinical examinations every six months. Subjects will be male or female between the ages of 50-100 and have a diagnosis of PD or RBD.

We are testing a 2D system designed to help people with Parkinson's disease practice their speech. In this study, participants will speak with a virtual character, called an embodied conversational agent, using a laptop. Our goal is to see if this technology is helpful and easy to use for people with Parkinson's disease to use. This research will help us learn whether using virtual characters at home could support long-term speech improvements.

The goal of the research study is to see if NEU-411 (1) will help prevent or slow the worsening of LRRK2 driven Parkinson's Disease (PD) and, (2) is safe. This study will also determine how your body processes NEU 411 and what NEU-411 does to your body. The study doctor will discuss with you whether you are eligible to be part of this study. As part of this study, you will receive either NEU-411 or placebo (inactive substance). The study drug is in tablet form and is taken by mouth. The study will last about 67 weeks. You will come in for 19 visits. In addition to in-person visits with the study team, you will be required to complete daily tests using a smartphone and occasionally be asked to wear a smartwatch continuously for 1-week periods. These technologies will be provided to you for use during the duration of the study and you will be trained on how to perform these activities. The NEU-411 is investigational and has not been approved by the US Food and Drug Administration as well as the investigational Companion Diagnostic (CDx).

Current surgical treatments for Parkinson's disease have associated risks that may prevent patients from being offered surgery called "deep brain stimulation" or DBS. This is mainly because electrodes have to be placed through brain tissue to reach the target. Stimulation at the surface of the brain might be a potential alternative, but current research has not shown consistent results, and this may be because the mechanism of action is not clear. In this study, we aim to stimulate and record the brain at the surface to help answer this question and potentially improve the consistency and effectiveness of this treatment.

The purpose of this research study is to learn how Deep Brain Stimulation (DBS), which targets a part of the brain called the subthalamic nucleus (STN), may affect thinking and memory in people with Parkinson's Disease (PD). We plan to include about 55 people with PD who have already had DBS surgery at MUSC's Clinical DBS Program.

As part of the study, participants will attend two visits after their DBS surgery. The first visit, which will last about three hours, includes going over the study information and consent form, collecting background information (demographics), and completing tests that measure thinking and memory (cognitive assessments) and speech. The second visit, also about three hours, will involve an MRI scan to look at how the brain's networks change when the DBS device is turned on and off. Participants have the option to combine visits 1 and 2. Participant's will also be invited to undergo an optional second scan. If participants consent, the second scan will be performed on a separate day than the first scan and therefore, there will be a total of 3 study visits.

These findings may help doctors and researchers make better decisions about which patients are most likely to benefit from DBS surgery and how to choose the best stimulation settings to reduce unwanted changes in thinking and memory.

Your participation in this study will help researchers understand genetic information about Parkinson's disease in Black and African Americans. BLAAC PD aims to generate genetic data on PD and non-PD Black and African American participants. To join this study, you must be over 18 years of age and identify as Black or African American. Subjects must have a diagnosis of PD or not have PD or any other neurological condition. The study will consist of one visit, at this visit you will be asked to answer a few questions and give a blood sample. You will not receive your genetic results.
