A patient with a degenerative disease was able to command Amazon’s Alexa digital assistant with his mind, the company behind the technological innovation announced Monday, letting him stream shows and control devices with only his thoughts.

The patient, who is living with amyotrophic lateral sclerosis (ALS), was able to make video calls, play music, stream shows, control smart home devices such as lights, shop online, and read books by using his mind to direct Alexa, according to the New York-based company.

ALS is a degenerative nerve disease that leads to muscle weakness and paralysis.
