Overview
Brief Summary
To compensate for insufficiency of diagnostic tools, the present study propose to look for the predictive factors of an early fitting by noninvasive ventilation.
Detailed Description
Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease. The diagnosis of this diaphragmatic dysfunction in the ALS subject is done all too often on the occasion of a hospitalization for acute respiratory insufficiency, which aggravates then the prognosis of the patients. The presence of these factors at diagnosis will allow more surveillance to detect early diaphragmatic insufficiency and establish a NIV (Non Invasive Ventilation), the only therapeutic measure definitely improving the quality of life and survival of patients. A clinical score will be established to determine the risk of early Non Invasive Ventilation (NIV) equipment.
Investigators
Eligibility Criteria
Inclusion Criteria
- •diagnosis of amyotrophic lateral sclerosis just performed,

Outcomes
Primary Outcomes
Early Surgical Clinical Score
Time Frame: One year after diagnostic
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)
Secondary Outcomes
- Sensitivity, specificity, negative and positive predictive values(One year after the diagnostic)
- Percentage of decrease(One year after the diagnostic)
- Slope of FVC decline(One year after the diagnostic)
- Quality of life score(One year after the diagnostic)
