Aquaporin-4 Single Nucleotide Polymorphisms in Patients With Idiopathic and Familial Parkinson's...

Parkinson Disease

The purpose of this study is to understand the relationship between problems in sleep, genetic variations in the Aquaporin-4 gene (AQP4), and the development of Parkinson's Disease.

Gait Characteristics and Cognitive Evolution in Parkinson Disease

Parkinson's Disease

Parkinson's disease (PD) is a chronic progressive nervous system disease with gradual motor impairment. Cognitive dysfunction is common in PD, even in the early stages, and it is characterized by impairments in executive, attention, memory, language and visuospatial function. Motor symptoms, in particular, alterations in gait, have been studied in clinical practice to assess disease progression, and its response to treatments, both farmacological and physiotherapeutic. Recent research on wearable technology in PD has shown that motor tests can be automated using wearable technology to eliminate human supervision and patient-reported data. Particularly, the quantitative gait analysis by using inertial devices has been proposed as a sensitive tool to longitudinally monitor gait worsening, response to dopaminergic treatment over time and cognitive dysfunction in PD patients. The aim of this prospective multicente observational study is to investigate whether the dysfunction of specific gait parameters may be correlated to cognitive impairment (Attention/Executive Function Domain) in a cohort of ambulatory PD patients followed for 3 years.

A Study to Analyze Symptoms Prevalent in Early PD (Dysphonia, Tremor)

Parkinson Disease

This is a web-based study that involves monitoring hallmark symptoms of Parkinson's Disease (PD), specifically dysphonia and tremor, using smartphone sensor data. The entire length of the study will only take 5 minutes, so volunteers will not have to repeatedly contribute data. The study is made up of 5 short, 10-second long activities, which include sustaining the short a vowel sound to monitor changes in vocal fundamental frequency and holding a smartphone in different positions on either side of the body to measure changes in amplitude. To be a part of this study, volunteers must have an iPhone that is running on the software iOS 13 or higher, because they will be asked to download a smartphone application from an online App Store.

Asymmetric DBS for PD : A Multicenter, Prospective, Single Arm, Open Label Study

Parkinson Disease

Deep brain stimulation (DBS) is an efficacious neurosurgical treatment for moderate-to-late stage Parkinson's disease (PD). The subthalamic nucleus (STN) and globus pallidus interna (GPi) are two targets extensively studied and used worldwide in treating PD. Although the conventional SYMMETRIC bilateral STN and GPi DBS are shown to be effective in controlling motor symptoms such as bradykinesia, tremor, and dyskinesia, each target has its pros and cons in terms of axial symptom control, medication reduction, cognitive decline, and programming. Therefore, we speculate that an ASYMMETRIC bilateral implantation of DBS leads (i.e., combined unilateral STN and contralateral GPi DBS) may be able to bring the greatest clinical benefits to PD patients by taking advantage of both bilateral STN and GPi DBS at the same time. The preliminary retrospective study containing eight PD patients undergoing asymmetric implantation of DBS demonstrated the safety and efficacy of this treatment strategy during short-term follow-up. This multicenter, single arm, open label study aims to prospectively investigate during the long-term follow-up the safety and efficacy of asymmetric DBS for PD in terms of motor and nonmotor symptoms, medication reduction, cognitive decline, and quality of life.

French Parkinson's Disease Cohort - NS-PARK

Parkinson Disease

The aim of NS-PARK cohort are to describe the natural history of Parkinson's disease (PD), and to propose patients stratification models based on PD pathophysiological mechanisms. Patients are included at all PD expert centers in France. Standardized demographic, diagnosis, motor and non-motor symptoms evaluation, and treatment information are collected, and clinical data are updated at each visit of the patient at the center. A blood sampling is perform at baseline for genetic testing and implement an associated biocollection.

Corticostriatal Contributions to Parkinson's Disease Cognitive Impairment

Parkinson Disease

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.

Video-oculography and Parkinson's Disease

Parkinson DiseaseIdiopathic

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.

Quantitative Imaging of Brain Glymphatic Function in Humans

Parkinson Disease

Recent immunological and physiological studies have provided evidence in support of a central nervous system (CNS) lymphatic drainage system in vertebrate animals, and preliminary evidence has suggested that a similar system exists in humans. If operative, this system may have central relevance to many vascular and fluid clearance disorders such as stroke, multiple sclerosis, Parkinson's disease, and Alzheimer's disease related dementia (ADRD): diseases which represent some of the most pressing healthcare challenges of the 21st century. Evaluating this possibility will require improved, robust imaging methods sensitive to lymphatic drainage dysfunction; as such, the goal of this work is to apply novel magnetic resonance imaging approaches, optimized already for evaluating lymphatic circulation in patients with peripheral lymphatic dysfunction, to quantify relationships between physiological hallmarks of ADRD and CNS lymphatic function in humans.
