Exploration of Differences in Metabolite Concentrations by 7Teslas NMR Spectroscopy in Striatum and Subthalamic Nuclei in de Novo Parkinsonian Patients and Control Subjects
Initially, the exploration of brain metabolism by Nuclear Magnetic Resonance Spectroscopy (MRS) of the high magnetic field proton (1H) (11.7T) applied to acute and chronic animal models of Parkinson's disease (PD) showed glutamatergic hyperactivity within the striatum, one of the components of the basal ganglia. Interestingly, acute administration of L-dopa …
Use of CereGate Therapy for Freezing of Gait in PD
A Multi-Center, Controlled Study to Evaluate Use of CereGate Therapy to Reduce Freezing of Gait in Participants Diagnosed with Parkinson's Disease.
Characterization of the Serotonin 2A Receptor Selective PET Tracer [18F]MH.MZ in Patients With Neurodegenerative Diseases
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.
Bilateral Closed Loop Deep Brain Stimulation for Freezing of Gait Using Neural and Kinematic Feedback
Deep Brain Stimulation of the subthalamic nucleus (STN) has become a standard of care, FDA-approved treatment for Parkinson's disease, with stimulation delivered at a constant amplitude and voltage, operating in an open-loop fashion that does not respond to a patient's current state. Although gait deficits and freezing of gait may …
Real-Time Levodopa Level Monitoring in Parkinson Disease
This project aims to develop a minimally invasive sensor device to monitor levodopa levels in real time. We will test the accuracy, tolerability, and safety of this device in people with Parkinson disease.
Investigating Inhibitory Control Networks in Parkinson's Disease
The purpose of this study is to investigate the brain activity associated with non-motor symptoms of movement disorders, including Parkinson's disease and essential tremor. These movement disorders commonly have significant non-motor features also, including depression, cognitive impairment, decreased attention, and slower processing speeds. The investigators are interested in the brain …
Neurophysiology Biomarkers of Cognitive Impairment Associated With Deep Brain Stimulation
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, …
Short Pulse Width Versus Low Frequency DBS in Parkinson's Disease
The aim is to compare the effect of reducing the conventional pulse width or frequency of stimulation for axial symptoms occurring after Subthalamic nucleus Deep Brain Stimulation (STN DBS) treatment. The participants will be assessed with chronic stimulation with conventional stimulation parameters, namely 60 us and 130 Hz, and after …
Transcranial Photobiomodulation as a Therapy for Patients With Parkinson's Disease: Relationship Between Pain and Brain Functional Connectivity (FBM)
Parkinson's disease is a progressive and degenerative neurological movement disorder that affects thousands of people. The disease is characterized by presenting motor and non-motor symptoms, as the disease progresses, it becomes more disabling, making it impossible for the individual to perform simple tasks. A non-motor symptom increasingly reported by patients …
Light Therapy Plus Exercise to Improve Motor, Non-Motor Symptoms and QoL in Parkinson's Disease
Parkinson's disease (PD) is a lifelong and progressive disease and is the second most common progressive neurodegenerative disease worldwide. This study will examine whether there are significant differences in motor (e.g., balance and gait) and non-motor (e.g., cognition, mood, smell & sleep ) symptoms and quality of life between the …
