Brief Summary: Dyspnea subjective experience of respiratory discomfort which produces negative emotional experience is the most common symptom of patients afflicted with chronic respiratory failure and its treatments are limited Amyotrophic Lateral Sclerosis ALS related - dyspnea due to diaphragmatic dysfunction is similar to dyspnea during mechanical inspiratory load activation of the supplementary motor area SMA The perception of pain and dyspnea is processed in similar brain areas insula dorsal anterior cingulate cortex amygdala and medial thalamus and in ALS relieving dyspnea by noninvasive ventilation NIV is associated with decreased pain thresholds Otherwise it is reported systemic elevations of pro-inflammatory cytokines in chronic pain patients correlating with intensity of pain and during respiratory load in healthy volunteers

The objectives are to evaluate the cytokines and endorphins rates variations after initiation of NIV in ALS patients and to correlate cytokines and endorphins rates with the intensity of the affective component and the intensity of the sensory component of dyspnea

The investigators will perform a prospective experimental study including 30 ALS patients Dyspnea ventilatory and cardiac settings electromyographic recording of the scalene muscle and biological assays ACTH endorphin Neuropeptide P BDNF IL1 IL6 IL8 IL10 TNF will be measured during spontaneous breathing and during NIV at different times after initiation

The investigators expect a reduction of immunological and neurobiological markers after relieving dyspnea by NIV This work could lead to the development of new treatments for dyspnea
