NCT06528964
The goal of this observational study is to compare the aggregation pattern of proteinopathies (alpha-synuclein, amyloid-beta, phosphorylated tau and transactive response DNA -binding protein 43 \[TDP43\]) in skin biopsies of patients with a neurodegenerative disease like Alzheimer's disease, frontotemporal lobe dementia, Parkinson's disease, atypical Parkinsonism, amyotrophic lateral sclerosis or normal pressure hydrocephalus. The main question it aims to answer is: * Is there a specific pattern of aggregation of proteinopathies in skin biopsies in each neurodegenerative disease in comparison to healthy control subjects? Skin biopsies will be analyzed using immunohistochemistry and immunofluorescence for detection of alpha-synuclein, amyloid-beta, phosphorylated tau and TAR DNA binding protein 43, and the aggregation patterns will be compared between patients with a neurodegenerative disease vs patient with normal pressure hydrocephalus vs healthy control subjects.
NCT05792332
This project aims to investigate whether an integrated model based on proactive and reactive telenursing monitoring coordinated by a parkinsonism nurse specialist (case manager) is able to improve care delivery and quality of life of patients with atypical parkinsonisms. This could reduce the risk (e.g. through health education counselling) and the severity of complications (e.g. falls). Main responsibilities of the Co-PI: project idea and supervision, coordination of the study, patient selection and recruitment, patient recruitment, participation in statistical analysis and drafting the manuscript. Co-PI is responsible of the rate of recruitment and drop-out
NCT04948684
Dystonia is a disabling symptom affecting both patients with idiopathic Parkinson's disease (PD) and atypical parkinsonism (AP). Botulinum toxinum (BoNT), by blocking muscle contraction, is a possible treatment for focal dystonia. The benefit of BoNT treatment has been proven in some focal dystonia associated with PD or AP. The investigators aim to give an overview of the efficacy of BoNT in a variety of focal dystonia in a large cohort of parkinsonian patients.
NCT03079310
Balance and gait impairment increases the risk of falls and contributes to a reduced quality of life and shorter survival in Parkinson disease (PD) and atypical Parkinsonism patients. In preliminary case studies, electrical epidural spinal cord stimulation (SCS) has been shown to significantly improve gait, postural instability, rigidity, and tremor. Controlled studies for optimizing which stimulation settings produce the best clinical response for mobility and gait, and achieving these results chronically are all significant unmet needs. Using quantitative laboratory and mobile technologies to test a range of stimulation settings, this research study aims to determine which SCS parameters or combination of parameters is best suited to effectively alleviate disabling symptoms experienced by each patient.
NCT03368300
The primary aim of this study is to estimate the frequency and to characterize clinically atypical parkinsonism in the French West Indies and Guyana.
