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.
ALS seems affecting men more frequently than women (ratio 1.4:1.0) [1, 6] and the age class with higher risk is 65â74. Prognosis is about 2â3 years from the beginning of the disease, though some 12â15 years survival cases have been observed, mainly in the older age classes [7,8,9,10,11].
