SAMPLE COLLECTION: Saliva collection from all the selected subjects will be performed following the Salivette (SARSTEDT) manufacturer's instructions. To limit variability in salivary content not related to ALS, saliva will be obtained from all subjects at a fixed time, after an appropriate lag time
Study groups will include ALS patients with and without respiratory failure as judged by their FVC and use of either noninvasive or invasive ventilation along with normal controls. For all patients, nutritional status will be assessed by measurement of weight, and determination of Urinary Urea
