Filter by: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 activity associated with these symptoms, and perform recordings of the surface of the brain, in addition to the typical recordings the investigators perform, during routine deep brain stimulation (DBS) surgery.
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 and acute, subchronic and chronic deep brain stimulation of the subthalamic nucleus (STN) normalizes these neurochemical profiles. Investigators also show an increase in glutamate levels in the STN ipsilateral to the substantia nigra pars compacta (SNpc) damaged by the neurotoxin, expected phenomenon, but also and surprisingly in the STN controlateral to the lesion. A degeneration of dopaminergic neurons is also observed in the controlateral SNpc at the lesion suggesting that the hyperglutamatergy of the controlateral STN to the lesion could promote neuronal death in the SNpc and thus participate in the progression and lateralization of the PD. Using 3T MRS in PD patients, as in other studies in humans, investigators do not see changes in glutamate and glutamine levels in the putamen of Parkinsonian patients. This difference between animal and human studies can be explained: 1. by the different rate of progression between PD in humans and animal models with plasticity phenomena limiting glutamatergic hyperactivity, 2. by the effect of treatment in PD masking changes in glutamate metabolism, 3. by limiting sensitivity in the detection of metabolites (Glutamate, glutamine, GABA) at 3T. The 7T 1H MRS improves the dispersion of chemical shifts of the metabolites studied, increases the sensitivity of the measurement, makes it possible to select regions of interest of smaller volumes (1 cm3) and thus limits the magnetic susceptibility effects that degrade the quality of the measured signal. This makes it possible to reliably separate glutamate and glutamine peaks. In this context, investigators propose to study the metabolic changes in a homogeneous group of de novo Parkinsonian patients, naive to any treatment intended to replace the missing dopamine. The gain in spatial resolution, contrast and signal will allow better characterization of localized anomalies in small-volume structures such as basal ganglia, putamen and STN.
This study aims to study, in patient with Parkinson's disease, mild to moderate stage (according to Movement Disorder Society Clinical Diagnostic Criteria for Parkinson's Disease, Postuma et al., 2015): - the evolution of oculomotricity markers over time. - the correlation between neurological evaluations (motor and non-motor scores), neuropsychological evaluations (cognitive disorders) and oculomotricity evaluation, over a follow-up period of 7 years. - the impact of antiparkinsonian drugs on the evolution of oculomotricity assessment by video-oculography. - the value of oculomotricity assessment by video-oculography as an evolutionary marker of the disease.
Deep brain stimulation (DBS) of the subthalamic nucleus or globus pallidus internus can improve motor symptoms Parkinson's disease (PD). However, it is not known whether DBS can help reduce the signs and symptoms of the limb-kinetic, ideomotor or ideational apraxia associated with PD or if apraxia can exist as a stimulation induced side effect from DBS therapy. In this study, we look to conduct a pilot study to examine the feasibility of characterizing the prevalence of apraxia in PD patients with chronic, stable DBS.
The PASS-PD study is set out to screen individuals from the general population with an increased risk for the development of Parkinson's Disease (PD) and to investigate this highly enriched cohort longitudinally for five year. A special focus is placed on implementation of ethical standards for early risk disclosure in PD.
This RCT study is designed to examine the extent to which L. plantarum PS128 can improve symptoms in PD patients. L. plantarum PS128 is a psychobiotic that regulates the level of dopamine in specific brain regions. Patients with PD will receive PS128 or placebo intervention for 12 weeks. Symptoms of PD will be clinically evaluated before and after the treatment, and the results will be compared.
This study is designed to examine L. plantarum PS128 can improve symptoms in early onset PD patients. L. plantarum PS128 is a psychobiotic that regulates the level of dopamine in specific brain regions. Patients with early onset PD will receive PS128 treatment for 12 weeks. Symptoms of PD will be clinically evaluated before and after the treatment, and the results will be compared.
The purpose of this research study is to examine the relationship between personal characteristics and satisfaction with care in those diagnosed with Parkinson's disease during the COVID-19 pandemic. Participants will take 4 different surveys regarding their satisfaction with care throughout the duration of the COVID-19 pandemic. The surveys in total should not take more than 30 minutes to complete
Current literature consistently demonstrates beneficial motor effects of dance-based therapies in Parkinson's disease, along with improved quality of life. Little is known about the non-motor gains following such therapy. To date, no RTC has been conducted to investigate the benefits of ballet dancing in Parkinson's disease. The investigators aim to recruit 160 people with Parkinson's to either: participate in a 12-week ballet-based dancing intervention followed by a 'social Tea and Biscuit' session, or 12-week usual treatment monitoring and 'social Tea and Biscuit' sessions taking place after each intervention session. This study employs a randomised, controlled, single-blind, hybrid type 2 design with a hybrid implementation protocol to investigate both clinical efficacy of the programme and implementation aspects. The project's primary outcome measure is centered around non-motor symptoms of PD. Other measures include motor assessments, wearable sensors and quality of life assessments. Due to COVID-19 pandemic, the delivery of the sessions will be a hybrid model - virtual sessions will be the primary method, with some capacity for in-person delivery when possible and deemed safe.
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.
