Corticostriatal Contributions to Parkinson's Disease Cognitive Impairment
Recruiting
The goal of this study is to learn more about the brain activity underlying Parkinson's disease cognitive impairment. The investigators will utilize neural recordings from corticostriatal structures performed during deep brain stimulation surgery to measure neural activity underlying nonmotor symptoms of Parkinson's disease.

Neurophysiology Biomarkers of Cognitive Impairment Associated With Deep Brain Stimulation
Recruiting
The study aims to investigate cognitive impairment associated with Deep Brain Stimulation (DBS) in Parkinson's Disease patients, with a focus on identifying neurophysiology biomarkers of DBS associated cognitive changes. Using neurophysiology data recorded during DBS surgeries and post-implantation, the research intends to identify biomarkers in order to optimize electrode placement, enhance programming, and ultimately minimize DBS-related cognitive side effects.

Real-World Study of ABBV-951 Subcutaneous Infusion to Assess Change in Disease Activity in Adult Participants With Parkinson's Disease
Recruiting
Parkinson's disease (PD) is a neurological condition, which affects the brain. PD gets worse over time, but how quickly it progresses varies a lot from person to person. Some symptoms of PD are tremors, stiffness, and slowness of movement. The purpose of this study is to evaluate how effective ABBV-951 is in treating adult participants with advanced PD in real world setting. ABBV-951 (foslevodopa/foscarbidopa) is an approved drug for the treatment of Parkinson's Disease. The main ROSSINI study... Read More

A Phase 2 Study of NEU-411 in Companion Diagnostic-Positive Participants With Early Parkinson's Disease
Recruiting
The goal of this Phase 2 clinical trial is to investigate the efficacy and safety of NEU-411 in men and women aged 40-80 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

Pimavanserin vs. Quetiapine for Treatment of Parkinson's Psychosis
Recruiting
Patients with Parkinson's disease (PD) sometimes experience symptoms affecting their movement, such as slowness, tremor, stiffness, and balance or walking problems. Many patients also have other symptoms not related to movement, called non-motor symptoms, which may affect one's mood or emotions, memory or thinking, or cause one to see or hear things that aren't real (hallucinations) or believe things that aren't true (delusions). Hallucinations or delusions, together called psychosis, occur in u... Read More

Phase 1/2a Clinical Trial of PR001 (LY3884961) in Patients With Parkinson's Disease With at Least One GBA1 Mutation (PROPEL)
Recruiting
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, immunogeni... Read More

Registry of Deep Brain Stimulation With the VERCISE™ System: Vercise DBS Registry
Recruiting
The purpose of this registry is to compile characteristics of world-wide outcomes for the use of Boston Scientific's commercially available Vercise DBS System in the treatment of Parkinson's disease. The utilization of Image Guided Programming (IGP), and other commercially available programming features, used as planning tools for the programming of patients with Boston Scientific's Vercise DBS System are also evaluated. Additionally, the utilization of the DBS Illumina 3D feature that may be... Read More

Physiological Brain Atlas Development
Recruiting
The NIH grant has funded the development of a physiological brain atlas registry that will allow us to significantly improve the data collectioin and use of physiological data into a normalized brain volume. This initially was used to improve DBS implants for Parkinson's Disease, Dystonia, Essential Tremor, and OCD, but now includes data acquired during all stereotactic brain procedures.

Characterization of the Serotonin 2A Receptor Selective PET Tracer [18F]MH.MZ in Patients With Neurodegenerative Diseases
Recruiting
It is hypothesize that patients with clinically diagnosed neurodegenerative diseases will have significantly different receptor occupancy of 5HT2A receptors compared to a healthy age/sex-matched control group. This will be tested by measuring 5HT2A receptor density using the PET radioligand (R)-\[18F\]MH.MZ in both populations.

Effect of Midodrine vs Abdominal Compression on Cardiovascular Risk Markers in Autonomic Failure Patients
Recruiting
The purpose of this study is to learn more about the effects of abdominal compression and the medication midodrine, two interventions used for the treatment of orthostatic hypotension (low blood pressure on standing), on hemodynamic markers of cardiovascular risk. The study will be conducted at the Vanderbilt University Medical Center and consists of a screening and 2 testing days, one with abdominal compression and one with midodrine. The total length of the study will be about 5 days.

Use of Accelerometer for Quantification of Neurogenic Orthostatic Hypotension Symptoms
Recruiting
The objective of this study is to find a more objective and accurate way to assess the efficacy of the treatment for neurogenic orthostatic hypotension. For this purpose, the investigators will use an activity monitor to determine the amount of time patients spend in the upright position (standing and walking; upright time) during 1 week of placebo (a pill with no active ingredients) and 1 week of their regular medication for orthostatic hypotension (midodrine or atomoxetine at their usual doses...
