Effects of Blood Pressure on Cognition and Cerebral Blood Flow in Parkinson Disease
Parkinson's disease (PD) is the second most common neurodegenerative disorder worldwide. Besides causing symptoms that impair movement, PD also causes non-moto…
Understand Me for Life: Using Noise-augmented Automatic Speech Recognition to Improve Intelligibility in Parkinson's Disease
The goal of this clinical trial is to learn whether noise-augmented feedback using automatic speech recognition improves intelligibility and social participati…
Quantitative Diagnostics of Parkinsonian Syndromes Using Multi-modal Neuroimaging and Deep Learning
The goals of this study are: 1) to identify biomarkers using neuroimaging that are associated with progression rate using statistical methods, and 2) to identi…
A Novel Instrument to Address Freezing of Gait in Parkinson's Patients
The goal of this clinical trial is to learn if the ParkinSense system, a customizable, multimodal, and adaptable cueing system, can assist with freezing of gai…
Subgaleal Cortical Electrodes in Patients With Parkinson's Disease Undergoing Deep-brain Stimulation Therapy for Sensing and Adaptive Deep-brain Stimulation Over a 24-hour Period.
The purpose of this study is to test a new way to treat Parkinson's disease (PD). Subjects will be implanted with deep brain stimulator (DBS) devices and elect…
Circuit-Based Deep Brain Stimulation for Parkinson's Disease P1A2&3 Catalyst
This study will help us better understand how the brain works in people with Parkinson's disease (PD). PD is a brain disease that gets worse over time, and aff…
Mild Cognitive Impairment Community Screening, Early Detection, and Therapeutic Intervention to Slow Down, or Stop the Progression of the Cognitive Impairment.
This study aims to evaluate the efficacy of community-based early detection and targeted interventions, including stem cell therapy and wearable non-invasive b…
Safety and Tolerability of Patterned Stimulation for DBS in the Home Setting
The primary objective of the proposed pilot study is to assess the safety and tolerability of active patterned Deep Brain Stimulation (pDBS) when administered …
Neocortical Microarchitecture of Executive Function Using Large-scale Intracranial Electrophysiology
This study is being done to the determine the ability and utility of using the Neuropixels probes in the human brain. A Neuropixels probe will be inserted into…
Effects of Rhythmic Auditory Stimulation (RAS) on Gait in Parkinson Disease (PD) Patients With DBS
Participants will be asked to walk along with the metronome beats (RAS) during the participants' stimulation state (ON or OFF) for four minutes for each state.…
Pilot Study of Open Label Homocysteine Management Therapy in Levodopa-treated Parkinson's Disease
This is a research study investigating elevated homocysteine in the blood of patients with Parkinson's disease who are currently receiving treatment with levod…
Quantitative Digitography to Evaluate the Efficacy of Image Guided Algorithmic DBS Programming
The goal of this clinical trial is to evaluate an automated deep brain stimulation (DBS) algorithm developed by Boston Scientific called Illumina 3D for motor …
