We’ve received a question from a reader which we believe would be of general interest. The writer asks:
"How does FEN President Janis Landis know there is no air hunger with nitrogen inhalation onset? Is this an assumption, inference, observation, result of experimentation? Please clarify."
Once ALS starts, it almost always progresses, eventually taking away the ability to walk, dress, write, speak, swallow, and breathe and shortening the life span. How fast and in what order this occurs is very different from person to person. While the average survival time is 3 years, about twenty percent of people with ALS live five years, 10 percent will survive ten years and five percent will live 20 years or more.
