“ALS is a disease that typically involves a gradual onset. The initial symptoms of ALS can be quite varied. One person may have trouble grasping a pen or lifting a coffee cup, while another may experience a change in vocal pitch when speaking.

The progression rate of ALS can be quite variable, as well. Although the mean survival time with ALS is two to five years after diagnosed with ALS, some people go longer for live five years, 10 years or even longer.  It varies from individual to individual after diagnosed with ALS.”
