Filter by:The goal of this observational study is to understand the clinical variability in a population of ALS patients using multidimensional biomarkers. The main questions it aims to answer are: - Which set of biomarkers explain genotypic-phenotypic correlations in ALS? - Which set of biomarkers can be used to subdivide the ALS population in homogeneous subgroups? Participants will undergo: - neurological evaluation - neurophysiological evaluation - neuropsychological evaluation - whole exome sequencing - biomarker measurement in CSF and plasma
Study Description: Characterization of Motor Neuron Disease Phenotypes The goal of this observational study is to understand the clinical presentation of motor neuron disease (MND) in patients attending the Neurology Department of the Istituto Auxologico Italiano. The main questions it aims to answer are: - What are the specific clinical phenotypes associated with MND? - How can these phenotypes contribute to a better understanding of the disease's underlying mechanisms and improve prognostic accuracy? Participants will undergo: - Clinical evaluation using validated scales - Neurophysiological and neuroradiological instrumental assessment - Neuropsychological evaluation - Collection of biological materials for genetic screening and biomarker assessment, if necessary.
Multidisciplinary management of amyotrophic lateral sclerosis (ALS) can significantly increase survival but also improve the quality of life of patients. The evaluation of cortical-spinal motor neuron damage is currently based only on the assessment of clinical data. However, the alteration of the central motor pathway and conduction can be identified and quantified by different techniques using motor-evoked potentials (MEP). The combined quadriceps test (QCT) has been developed to assess central and peripheral motor pathway conduction. This test allows to quantify central and peripheral part of a mixed disorder, and to detect physiological hyporeflexia or hyperreflexia which, in the case of suspected ALS, can lead to interpretation problems. The evolution of the QCT parameters during the course of pathology will lead to determine the preponderance of an initial central involvement, but also its extension throughout the pathology. The study of these parameters as well as the clinical course of the disease could reveal a correlation between peripheral and central involvement. This link would provide arguments in favor of pathophysiological hypotheses of disease onset and progression. From a prognostic point of view and depending on the quantification of central and peripheral involvement, the QCT would make it possible to characterize the different ALS phenotypes. This phenotypic characterization would help identify prognostic factors at diagnosis. The investigators propose a cohort study with the exploration of central motor neuron damage by QCT during the course of ALS in order to provide arguments for a better mechanistic understanding and follow-up of this disease with a poor prognosis.
ActiALS is a multicentric academic study. Patients with amyotrophic lateral sclerosis (ALS) may be included on a voluntary basis. The investigators plan to include a group of approximately 30 patients with ALS. The investigators have planned to assess patient every three months for a year. After each visit, participants will wear Actimyo for one month daily.
The aim of this study is to describe the changes in the neuromuscular connection in patients with amyotrophic lateral sclerosis (ALS). The study consist of three substudies that have the following main hypothesis: 1. that ALS patients do not demonstrate equal capacity for muscle reinnervation and that reinnervation preserves muscle function and thereby slows down progression. 2. that blood concentrations of c-terminal agrin fragment (bCAF) reflect neuromuscular transmission deficiency and that blood concentration of neural cell adhesion molecule reflects degree of muscle denervation in patients. 3. that ALS patients with decrement when examined with repetitive nerve stimulation have more physical fatigue, slower progression, higher degree of reinnervation and higher bCAF compared to ALS patients without decrement. There will be 3 inclusion groups. 1. patients referred for neurophysiological examination on suspicion of motor neuron disease. 2. healthy controls 3. disease control: patients with another motor neuron disease with slow progression. All participants will be invited for at least 1 visit (baseline). If participants in group 1 eventually receive the diagnosis of ALS they will be invited for 2 additional visits 4 og 8 months after baseline visit, respectively. Examinations will consist of: - nerve conduction study - repetitive nerve stimulation (except for healthy controls) to examine impairment of the neuromuscular connection. - motor unit number estimation with MScanFit to estimate number and size of motor units. - ultrasound examination of muscles to measure size and condition of muscles. - questionnaires on fatigue and functional status. - blood sample for measurement of specialized analysis (c-terminal agrin fragment and neural cell adhesion molecule) and routine analysis (liver and kidney function as well as neurofilament light chain) - muscle strength assessment manually and by dynamometer to follow progression of muscle weakness - bioelectrical impedance measurement to follow the overall body composition.
The primary purpose of this study is to evaluate the safety and tolerability of VRG50635 in participants with ALS.
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease affecting both upper and lower motor neurons. Electroneuromyography is an important tool for the diagnosis. Previous studies have shown that different components of the blink reflex, such as the latencies of homo- and contralateral R2 responses can be affected. Studies have found that a contralateral R1 component can appear in neurological diseases with affection of the central nervous system especially upper motor neuron, such as HTLV1 infection. Thus, you aim to determine if a contralateral R1 component could be present in ALS.
The New York Stem Cell Foundation (NYSCF) Research Institute is performing this research to accelerate diverse disease research 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 store the samples for future use. Through this research, researchers hope to identify future treatments or even cures for the major diseases of our time.
This study assesses the performance of serum neurofilament light chain (sNfL) in amyotrophic lateral sclerosis (ALS) in a wide range of disease courses, in terms of ALS progression, disease duration, and tracheostomy invasive ventilation (TIV). The aim of the research project is to investigate the correlation between NfL serum concentration and the natural course of the disease, the ALS progression rate, and specific phenotypes of ALS. Furthermore, the performance of NfL as a therapeutic biomarker will be studied. A systematic analysis of the NfL serum concentration in a cohort of 3,000 ALS patients using the Single Molecule Analysis method (SIMOA) will be performed. This analysis is carried out as a multi-center study.
Using a MRI gait motor imagery paradigm in ALS patients in order to study how ALS affects the function of the central neural networks involved in gait function, we showed a reorganization of the motor networks that represents a compensatory response to the dysfunction of the networks involved in gait function. Our main hypothesis is that by providing coherent proprioceptive input to the sensorimotor integration areas, gait training with an exoskeleton may boost compensatory network reorganization and help to maintain function. We hypothesize that this can be achieved through a locomotion training strategy that reproduces normal gait motor patterns and appropriate sensory feedback. Gait training with an exoskeleton can meet these needs. The Atalante exoskeleton offers unique potential thanks to its cutting-edge technological features, hands-free functions and availability in numerous centers across Europe. Evaluation of its safety and efficacy in ALS is of the utmost interest in order to generalize this new approach in ALS.
