Facts You Should Know. ALS is not contagious. Although the life expectancy of a person with ALS averages about two to five years from the time of diagnosis, this disease is variable, and many people can live with the disease for five years and more. More than half of all people with ALS live more than three years after diagnosis.
And youâre right; it takes on average about nine to 12 months for someone to be diagnosed with ALS, from the time they first began to notice symptoms. Getting the proper evaluation in a timely way is important, especially since we have a drug, Rilutek, which has been shown to help delay the progression of ALS.
