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 progressive, meaning that the symptoms gradually worsen over time. The rate of disease progression varies extensively from person to person. The average lifespan of the individual after diagnosis has been reported to be 2 to 5 years.
