Neuroplasticity in RBD
REM sleep behavior disorder is a parasomnia that reflects the presence of alpha-synucleinopathy in the brain and is highly predictive of eventual phenoconversion to Parkinson's disease, dementia with Lewy bodies, or multiple system atrophy over the course of years to decades. Neuroplastic adaptations in the brain during the prodromal stage …
rTMS to Improve Cognition in Parkinson's
The purpose of this study is to examine safety, feasibility, and the behavioral and brain effects of a non-invasive treatment, repetitive transcranial magnetic stimulation (rTMS), for Veterans with Parkinson's disease or atypical parkinsonism and mild impairments in their thinking. The hypothesis is that rTMS can improve thinking for people with …
Closed-loop DBS in Parkinson's Disease
Closed-loop DBS is an emerging neuromodulation pattern in Parkinson's disease with dyanmic adjustment of stimulation parameters to patients' disease fluctuations and state of activity. The purpose of this study is to verify the long-term safety and effectiveness of closed-loop DBS. Through comparing with open-loop DBS, the study also determine whether …
The Effect of Spinal Mobilization on Respiratory Parameters in Parkinson's Disease Patients
Parkinson's patients suffer from respiratory distress for different reasons. It is thought that physiotherapy methods that have an indirect effect on the diaphragm can improve respiratory functions. The aim of this study is to investigate the effects of spinal mobilization and diaphragmatic breathing techniques on respiratory function.
Mindfulness-based Intervention for People With Parkinsonian Tremor
Mindfulness meditation is an approach that has shown interest in treatment of anxiety in Parkinson's disease. This pilot study aims to assess a more specific effect on tremor using Essential Tremor Embarrassment Assessment and inertial sensors allowing monitoring during sessions and in daily life. This study will focus on 20 …
GRoningen Early-PD Ambroxol Treatment
The most common genetic risk factor for Parkinson's Disease is a heterozygous mutation of the GBA1 gene, encoding the lysosomal enzyme glucocerebrosidase (GCase). Reduced GCase activity is associated with aggregation of the protein alpha synucleine (aSyn) in the central nervous system, which is related to the pathological cause of PD. …
Physiology, Imaging and Modeling of Essential Tremor
This project aims to investigate novel ways to deliver brain stimulation to Essential Tremor (ET) patients by introducing software changes to their existing devices. The study team aims to investigate safety and efficacy of these new stimulation parameters in patients with ET.
Molecular Characterization of Induced Neuronal Cells in Parkinson's Disease
To describe the molecular, electrophysiological and morphological expression profile of dopaminergic neurons derived from fibroblasts of patients with Parkinson's disease.
Novel DBS Stimulation Patterns for Treatment of Parkinson's Disease
This is an open-label, non-randomized, proof-of-concept comparison of clinical vs. research stimulation patterns in patients with Parkinson's disease (PD) being treated with Deep Brain Stimulation (DBS) through the Medtronic Percept PC DBS device. The investigators hypothesize that stimulation patterns designed to better target excessive synchrony in a patient-tailored manner may …
Understanding Motivation in Parkinson's Patients Through Neurophysiology
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.
