Amyotrophic lateral sclerosis, also known as ALS, MND and Lou Gehrig's disease, is a neurological disease that attacks the motor neurones responsible for the use of voluntary muscles. ALS typically progresses rapidly, causing severe weakness that can develop into complete immobility. Along the way, speech impairment may develop into an inability to communicate effectively.

While the symptoms of ALS are overwhelming and place enormous pressure on patients - as well as their families and caregivers - technology is helping many with ALS communicate effectively, and live more comfortably and independently.
