Answer

Stephen Hawking is living with ALS, or amyotrophic lateral sclerosis, according to Scientific American. ALS is also known as Lou Gehrig's disease and is a motor neuron disease.

Most live only five years after diagnosis, while Hawking has lived decades. Stephen Hawking is confined to a wheelchair and uses his cheek to operate his trademarked computer system that allows him to speak and work.
