DBS and Respiration
Parkinson DiseasePatients referred to neurosurgery routinely and safely undergo deep brain stimulation (DBS) for treatment of neurological conditions, most commonly Parkinson's disease. The investigators have observed that respiratory problems (breathlessness) sometimes occur subsequent to DBS of the subthalamic nucleus (STN). This study aims to determine whether this is indeed a consequence of STN stimulation. Secondary objectives include identification of the respiratory physiological mediators of any interoceptive neuromodulation observed, changes in daily physical activity and MRI structural connectivity analysis.
Predictors of Parkinson's Disease Progression
Parkinson DiseaseCognitive Dysfunction1 moreit is a prospective longitudinal observational study, aiming to to identify clinical, and biochemical baseline predictors of motor and non-motor PD progression in sample of Egyptian patients. it measures the baseline motor, non-motor, biochemical and imaging characteristics at enrollment and its relation to PD progression over 3 years
Deep Brain Stimulation (DBS) Retrospective Outcomes Study
Parkinson DiseaseEssential Tremor1 moreThe primary objective of this study is to characterize real-world clinical outcomes of Deep Brain Stimulation (DBS) using retrospective review of de-identified patient records.
Using Wearable and Mobile Data to Diagnose and Monitor Movement Disorders
Essential TremorParkinson Disease5 moreThe purpose of the research is to better understand the motor behavior of individuals in health and disease. The specific purpose of this project is to identify if we can utilize a smartphone to diagnose different movement disorders and monitor their symptoms. A. Objectives Estimate symptom severity of Essential tremor (ET), Parkinson's disease (PD), Huntington's disease (HD), Primary focal dystonia (PFD), spinocerebellar ataxia (SCA), and Functional movement disorders (FMD) using a smartphone-based application Differentiate individuals with the different movement disorders from healthy controls based on features from the smartphone data Differentiate individuals with a specific movement disorder from people with other movement disorders based on features from the smartphone data B. Hypotheses / Research Question(s) We hypothesize that we can estimate the severity of symptoms using a smartphone application and that, using those estimates, we can differentiate individuals with movement disorders from healthy controls and from people with other movement disorders.
Counterfactual Thinking and Decision-making in Parkinson's Disease
Parkinson DiseaseThe aim of this research is to verify the ability of counterfactual thinking about medical decisions in individuals affected by Parkinson's Disease when compared to healthy individuals.
Cognitive Testing Online in Parkinson's Disease
Parkinson DiseaseThis is a feasibility and pilot study. Though large-scale online neurocognitive testing is increasingly being done in psychiatry, there are no such efforts in Parkinson's research. Thus a large part of this pilot study will be to demonstrate feasibility and reliability, and use this experience to develop a feasible protocol for ongoing research. The specific short-term objectives are: To establish the feasibility of performing large-scale deep cognitive phenotyping using online cognitive testing. To demonstrate that online neurocognitive testing is valid and reliable in a smaller sample of locally recruited participants tested both in-lab and online.
Utilizing Neural Signatures and Virtual Reality to Advance DBS Programming
Parkinson DiseaseDBS3 moreThe project uses virtual reality technology to recreate situations that cause freezing of gait in individuals with Parkinson's disease. Individuals who underwent deep brain stimulator (DBS) surgery for Parkinson's disease will walk through a virtual reality environment while brain signals are recorded from the DBS device. The goal is to better understand what occurs in the brain during freezing of gait.
Drug Discovery for Parkinson's With Mutations in the GBA Gene
Parkinson DiseaseGaucher Disease2 moreThe New York Stem Cell Foundation (NYSCF) Research Institute is performing this research to accelerate Parkinson's disease research and drug development by using cells from the body (such as skin or blood cells) to make stem cells and other types of cells, conduct research on the samples, perform genetic testing, and/or store the samples for future use. Through this research, researchers hope to identify future treatments or even cures for Parkinson's disease.
Misfolded Proteins in the Skin of People With Parkinson's Disease and Other Parkinsonism
Parkinson DiseaseParkinsonism4 moreThe purpose of this study is to determine whether identification of misfolded proteins in the skin will help to determine what sort of parkinsonism someone has. We seek to demonstrate whether someone has a synucleinopathy such as Parkinson's disease (PD), multiple system atrophy (MSA), or dementia with Lewy bodies(DLB), as opposed to a tauopathy such as progressive supranuclear palsy (PSP) or corticobasal degeneration (CBD) or no parkinsonism at all (control).
International Validation of Two Non-motor Scales in PD (NFS and SPARK)
Parkinson's DiseaseNon-motor SymptomsThe goal of this project is to develop the international validation of two new rating scales, the Neuropsychiatric Fluctuations Scale (NFS) and the Shame in PARKinson's disease (SPARK) Scale, in order to improve the understanding of the extent and severity of non-motor symptoms in Parkinson's disease (PD).
