Amyotrophic lateral sclerosis (ALS) is a highly progressive, degenerative disease of the nervous system. It interferes with neurons that control muscle movement, and it causes difficulty in walking, talking, and hand usage.

If you suspect ALS, see your doctor as soon as you can. That way, they can run tests to rule out other diseases and get you treated quickly.
