ALS is a fatal disease: Most ALS patients die within two to five years of diagnosis. Common causes of death are respiratory failure and/or cardiac problems related to insufficient oxygen. Patients may also suffer respiratory infections, such as pneumonia.

ALS is age related; most people find out they have it when they are between 55 and 75 years of age, and live from 2 to 5 years after symptoms develop.
