Outcome Measures
Primary Outcomes (1)
Early Surgical Clinical Score
An Early Surgical Clinical Score will be established taking into account the independent variables correlated to diagnosis at early fitting. Clinical Variables : * Presence of bulbar involvement or not * Time from onset of first symptoms to diagnosis * Amyotrophic Lateral Sclerosis Functional Rating Scale - Revised (ALSFRS-R) score : The Amyotrophic Lateral Sclerosis Functional Ra ting Scale (ALSFRS) is an instrument for evaluating the functional status of patients with Amyotrophic Lateral Sclerosis. It can be used to monitor functional change in a patient over time. * Presence of another underlying respiratory disease Functional Variables : * Time from onset of first symptoms to diagnosis of ALS * Presence of another underlying respiratory pathology * Forced Vital Capacity (FVC) measurement * PaCO2 measurement * Measure Sniff Nasal Inspiratory Pressure (SNIP) * Measurement of diaphragmatic activity on ultrasound * Parameters of the Polysomnography (PSG)

Interventions
The study compare the diagnostic variables in patients who received Non invasive ventilation equipment one year after diagnosis with the patient who don't need it. For the independent variables, the present study determine a threshold at the diagnosis for which an early fitting risk appears The diagnostic variable are : * Age of the patient * Sex * Presence of bulbar involvement or not * Time from onset of first symptoms to diagnosis of ALS * Score ALSFRS-R * Presence of another underlying respiratory pathology (COPD, asthma ...) * FVC measurement (Forced vital capacity) * PaCO2 measurement * Measure SNIP (Sniff nasal inspiratory pressure) * Measure of Pimax (Pressure inspiratory maximal) * Measurement of the nocturnal desaturation index (number of desaturation less than 90% per hour of sleep)
Eligibility Criteria
You may qualify if:
- diagnosis of amyotrophic lateral sclerosis just performed,
- Patient who do not have the criteria for fitting by NIV and who have a Vital capacity ≥ 70% of theoretical values
You may not qualify if:
- Patient under court bail/ guardianship
- Lack of consent for participation in the study
- Presence of criteria for setting up the NIV for diagnosis according to the HAS (HealthCare Analytics Summit) 2006 recommendations
- Vital capacity \<70% of the theoretical values
- Patient under Continuous Positive Pressure (CPP) or NIV for a respiratory pathology other
