Remote Speech and Swallowing Assessment in ALS

Amyotrophic Lateral Sclerosis

The investigators propose a longitudinal home study of ALS patients to measure the severity of speech and swallowing (bulbar) impairment via a smartphone-based, remote speech and swallow assessment (rSSA). The study is designed to assess the feasibility and validity of such a monitoring intervention. Furthermore, it is proposed that regular monitoring of these two bulbar processes may shed light on their co-evolution over the course of ALS.

Alleviating Persistent Dyspnea in Amyotrophic Lateral Sclerosis Patients Treated With Non-Invasive...

Amyotrophic Lateral Sclerosis

The evolution of amyotrophic lateral sclerosis (ALS) is marked by dyspnea, anxiety and pain, major determinants of suffering induced by this disease. The only palliative treatment for respiratory failure is non-invasive ventilation (NIV), which compensates failing respiratory muscles and relieves dyspnea, improves quality of life and increases life expectancy. In ALS patients, the persistence of dyspnea outside of NIV sessions has highlighted the need for therapeutic alternatives in the treatment of persistent dyspnea, including immersive virtual reality (IVR) and auditory distraction through music (music therapy). This study evaluates the effect of IVR on respiratory discomfort in ALS patients with persistent dyspnea treated with NIV.

Validation of the "ExSpiron©" in Patients With ALS

Amyotrophic Lateral SclerosisNeuromuscular Diseases

Non-invasive ventilation (NIV) in patients diagnosed with amyotrophic lateral sclerosis (ALS) is nowadays common practice to provide comfort at the end stage of the disease. As complaints vary there is the need of a non-invasive device to measure respiratory volume to objectify complaints. The ExSpiron© is a device for non-invasive monitoring of respiratory volume. The validation of this monitor in patients with ALS is the aim of this study. The hypothesis is that the ExSpiron© delivers a valid assessment of respiratory volume in patients with ALS

Stratification of Presymptomatic Amyotrophic Lateral Sclerosis: the Development of Novel Imaging...

Amyotrophic Lateral Sclerosis

Amyotrophic lateral sclerosis (ALS) is a relentlessly progressive neurodegenerative disorder with no effective disease-modifying therapies at present. The disease is sporadic in 90 % of the ALS patients. Up to 40 % familial ALS cases and up to 25% of familial frontotemporal dementia (FTD) are caused by autosomal dominant GGGGCC hexanucleotide repeat expansions in the C9orf72 gene. The presymptomatic phase of the disease represents a unique opportunity to evaluate mechanisms of disease propagation, characterise patterns of anatomical spread, validate staging systems and appraise the comparative sensitivity profile of emerging imaging modalities. Very few spinal cord imaging studies currently exist in ALS despite their potential to characterise both the lower and upper motor neuron components of the disease. This prospective longitudinal study of asymptomatic and symptomatic c9orf72 hexanucleotide carriers will use a purpose-designed spinal and brain imaging protocol and comprehensive clinical, genetic, electrophysiological and neuropsychological profiling. Newly developed imaging techniques such as spinal cord NODDI, spinal fMRI, quantitative thoracic cord imaging will be implemented in addition to established spinal cord and brain imaging techniques.

Technical Evaluation of Earswitch Phase A

Motor Neuron Disease

The goal of this study is to test the Earswitch device in both participants with and without assistive technology (AT) needs. The main aim is to determine how robust the Earswitch is in detecting voluntary eardrum movements (known as ear rumbling) and see how well the Earswitch fits with other assistive technology. To do this, participants will be asked to wear the Earswitch device and voluntarily contract their TT to complete a series of tasks shown on screen and/or explained audibly. Participants will be asked to complete questionnaires to understand their opinions about the effectiveness, usability, and comfort of both their current device (if applicable) and the Earswitch. This feedback will be invaluable in developing the Earswitch.

Evaluation of the Early Use of the Pressure Relaxer in the Respiratory Impairment of Patients With...

Amyotrophic Lateral Sclerosis

Amyotrophic lateral sclerosis (ALS) is a rare and serious neurodegenerative disease causing degeneration of motor neurons. . It leads to a progressive paralysis of the muscles involved in voluntary motricity. In France, its incidence is 2.5/100,000 inhabitants per year. The death of patients is mainly caused by a progressive attack of the respiratory muscles. Indeed, the thorax is no longer actively mobilized to the maximum amplitude, it will lose its flexibility. A restrictive syndrome sets in followed by alveolar hypoventilation. Bronchial congestion may be concomitant. Management is then based on non-invasive ventilation (NIV). This step, which is difficult for patients to accept psychologically, must be delayed as much as possible. However, to date, there are no precise recommendations on preventing the appearance of this restrictive syndrome and on slowing down the deterioration of lung function in patients. The pressure relaxer (RLX) is an instrumental aid allowing on the one hand to mobilize the thorax thanks to hyper insufflations, and on the other hand to increase the effectiveness of the cough. The use of this device in physiotherapy is part of the HAS recommendations to promote decluttering. However, we believe that RLX in patients with ALS, through the pulmonary alveolar recruitment it induces, could be relevant at an earlier phase, for the prevention of the decline in pulmonary functions: the restrictive syndrome, bronchial congestion and alveolar hypoventilation. So ultimately, the quality of life and survival of these patients would be improved. It is in this context that this multicenter randomized controlled study RELAX'SLA takes place in order to evaluate the effects of the early use of the pressure relaxer on the respiratory impairment of patients with ALS.

Cell Signaling, Reinnervation and Metabolism in Kennedy Disease and Amyotrophic Lateral Sclerosis...

Amyotrophic Lateral SclerosisKennedy Disease

Amyotrophic lateral sclerosis (ALS), is a rapidly progressive neurodegenerative disorder, usually leading to death from respiratory failure in 3-5 years. Riluzole, the only drug currently available, only modestly prolongs survival and does not improve muscle strength or function. In ALS, loss of functional motor neurons is initially compensated for by collateral reinnervation and strength is preserved. In the majority of ALS patients, as the disease progresses, compensation fails leading to progressive muscle weakness. Conversely, in long-term ALS survivors, slow functional decline is correlated with their ability to maintain a successful compensatory response to denervation over time. Compensatory collateral reinnervation is thus essential for functional motor preservation and survival, and elucidation of the molecular mechanisms involved is crucial to help identify new therapeutic targets. Energy metabolism and glucose homeostasis modifications also influence disease clinical course but the mechanisms by which they contribute to the progression of ALS are unknown. Weight loss is an independent negative prognostic factor for survival and, by contrast, ALS risk and progression are decreased in individuals with high body mass index and non-insulin-dependent diabetes mellitus. Insulin shares many common steps in its signaling pathways with insulin-like growth factor 1 (IGF-1), and is thus at the interface between glucose homeostasis regulation and maintenance of muscle mass. However, the contribution of insulin signaling to preservation of muscle innervation and function in ALS has never been investigated. With this study, we aim to determine the role of insulin signaling pathways in maintenance of collateral reinnervation and muscle function in ALS. We will also investigate the link with the disease-modifying effect of metabolic and glucose homeostasis perturbations, by identifying the contribution of metabolic profiles to preservation of skeletal muscle innervation and motor function in patients with ALS. For this purpose, we will determine the whole-body and skeletal muscle metabolic profiles of 20 patients with ALS and correlate these results to collateral reinnervation ability quantified on muscle biopsy specimens. For each patient, we will use both clinical and electrophysiological methods to evaluate motor function and motor neuron loss over time. Body composition, insulin secretion, insulin resistance level and serum concentrations of IGF-1 axis components will be determined. A motor point muscle biopsy will be performed for morphological analysis of neuromuscular junctions and quantification of innervation by confocal microscopy. Activation of insulin/IGF-1 canonical signaling pathways and metabolic pathways of glucose homeostasis will be quantified in muscle specimens. Skeletal muscle and whole-body metabolic parameters will be analyzed together and correlated with clinical assessment of motor function, electrophysiological data, and innervation quantification results. For comparison, 10 healthy subjects of similar age and 10 patients with spinal and bulbar muscular atrophy - a slowly progressive motor neuron disorder with maintenance of effective collateral reinnervation - will be used as controls. This study will be the first to address the question of the contribution of insulin signaling pathways and metabolic profiles in maintenance of muscle reinnervation and function in ALS patients. The molecular mechanisms identified will be new targets for future treatments promoting compensatory reinnervation and slowing disease progression in ALS. Ultimately, this translational project could have a significant therapeutic impact in disorders with muscle denervation and collateral reinnervation as a compensatory mechanism, such as spinal muscle atrophy or peripheral neuropathies.
