Filter by:The prevalence of Multiple System Atrophy (MSA) is reported to be between 3.4 - 4.9 cases per 100,000 population. The estimated average incidence is 0.6 - 0.7 cases per 100,000 people per year. Many patients are not diagnosed properly during their lifetime because of the difficulty in differentiating MSA from other disorders. Approximately 29 - 33% of patients with isolated late onset cerebellar ataxia and 8 - 10% of patients with parkinsonism will develop MSA. There are currently no therapies that can cure or stop the progression of the disease. The current pharmacological therapy is only to relieve symptoms. Mesenchymal stem cells (MSC) are considered an efficient source of cells for therapy, because they can be safely harvested and transplanted to donors or patients, have low immunogenicity, and have broad therapeutic potential. Results from preliminary preclinical and clinical trials indicate the potential of MSC-based treatment in meeting several key aspects of neurodegeneration. Stem cell-based therapy for neurodegenerative diseases aims to stop clinical damage by regenerating and by providing local support for damaged tissue, in addition after transplantation, MSCs have been shown to be capable of penetrating the lesion area and thus have great potential use as a means of administering therapeutic agents. The subjects of this study were patients who experienced possible MSA based on the consensus clinical criteria for MSA. There will be three treatment groups with a total sample of 5 subjects each. Group 1 will receives MSC-Adipose Autologous with doses 2x50 million cells intratechally. Group 2 will receives MSC-Umbilical Cord Allogeneic with doses 2x 50 million cells intratechally. Group 3 will receives MSC-Umbilical Cord Allogeneic with doses 2x50 million cells intratechally and 2x10cc secretome MSC from Adipose Intravenously. Clinical improvement will be evaluated using the UMSARS scale, PET-Scans, MRI, DaTScan, IGF-1, BDNF, Sympathetic skin respons (SSR), EMG, Composite Autonomic Severity Score (CASS), High definition-Optical coherence tomography (HD-OCT), ERG, VEP, Log MAR chart, Ishihara test and side adverse effect on MSC. This study is divided into six timeframes : Before an implantation, First Month after second implantation, Third month after secondary implantation, Sixth month after second implantation, Ninth month after second implantation and Twelve month after second implantation. The differences between the test variables are then used as an indicator to assess clinical improvement within the subjects.
Based on a prospectively collected data analysis, a new tool, namely CoMDA (Cognition in Movement Disorders Assessment) is developed by merging each item of Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA) and Frontal Assessment Battery (FAB). A machine learning, able to classify the cognitive profile and predict patients' at risk of dementia, is created.
Cognitive neurodegenerative diseases are a major public health issue. At present, the diagnosis of certainty is still based on anatomopathological analyses. Even if the diagnostic tools available to clinicians have made it possible to improve probabilistic diagnosis during the patient's lifetime, there are still too many diagnostic errors and sub-diagnostic in this field. The arrival of biomarkers has made it possible to reduce these diagnostic errors, which were of the order of 25 to 30%. This high error rate is due to different parameters. These diseases are numerous and often present common symptoms due to the fact that common brain structures are affected. These diseases evolve progressively over several years and their early diagnosis, when the symptoms are discrete, makes them even more difficult to diagnose at this stage. In addition, co-morbidities are common in the elderly, further complicating the diagnosis of these diseases. At present, the only cerebrospinal fluid (CSF) biomarkers that are routinely used for the biological diagnosis of neurodegenerative cognitive pathologies are those specific to Alzheimer's disease: Aβ42, Aβ40, Tau-total and Phospho-Tau. These biomarkers represent an almost indispensable tool in the diagnosis of dementia. It is therefore important to determine whether Alzheimer's biomarkers can be disrupted in other neurodegenerative cognitive pathologies, but also to find biomarkers specific to these different pathologies by facilitating the implementation of clinical studies which will thus make it possible to improve their diagnosis.
The objective of this study is to find a more objective and accurate way to assess the efficacy of the treatment for neurogenic orthostatic hypotension. For this purpose, the investigators will use an activity monitor to determine the amount of time patients spend in the upright position (standing and walking; upright time) during 1 week of placebo (a pill with no active ingredients) and 1 week of their regular medication for orthostatic hypotension (midodrine or atomoxetine at their usual doses). Total upright time (i.e. tolerance to standing and walking) will be compared between placebo and active treatment to test the hypothesis that it can be used to assess the efficacy of the treatment for orthostatic hypotension and whether this outcome is superior to the assessment of symptoms using validated questionnaires.
The purpose of this study is to investigate the effect of comprehensive swallowing rehabilitation in patients with multiple system atrophy.
This is a non-interventional observational study designed to systematically record the results of routine laryngeal examinations and specific characteristics of dysphagia in patients with multiple system atrophy (MSA), Parkinson's disease (PD) and progressive supranuclear palsy (PSP) and related 4repeat tauopathies. The results of a fiberoptic / flexible endoscopic evaluation of swallowing (FEES) while performing a structured task protocol will be recorded. If available, laryngeal electromyography (EMG) results will also be recorded. In addition to the examination results, demographic and disease-specific data are collected, and two questionnaires, the Swallowing Disturbance Questionnaire for Parkinson's Disease (SDQ-PD) and the swallowing specific Quality Of Life Questionnaire (SWALQOL), are administered.
The Synuclein-One Study will be evaluating α-synuclein in patients with Parkinson's disease, Multiple System Atrophy, Dementia with Lewy bodies and Pure Autonomic Failure. Using a simple diagnostic test will improve clinical accuracy in diagnosing, earlier diagnosis, and distinguish between neurodegenerative diseases.
The investigators aim to learn more about symptoms suggestive of a neurodegenerative process.
The objective of this randomized, double-blinded, placebo-controlled Phase 1 investigation is to evaluate the safety and potential clinical effect of AAV2-GDNF delivered to the putamen in subjects with either a possible or probable diagnosis of Multiple System Atrophy.
The purpose of this study is to learn more about the effects of abdominal compression and the medication midodrine, two interventions used for the treatment of orthostatic hypotension (low blood pressure on standing), on hemodynamic markers of cardiovascular risk. The study will be conducted at the Vanderbilt University Medical Center and consists of a screening and 2 testing days, one with abdominal compression and one with midodrine. The total length of the study will be about 5 days.
