What Is ALS Disease?
2. Causes
ALS is caused by the deterioration of motor neurons in the central nervous system. These are specialized cells that help to pass messages around the body in the form of electrical impulses. As these cells gradually deteriorate, so the body will become less able to send messages to muscles to tell them to move.
Of the people that have ALS, the condition was inherited in between 5% to 10% of cases. It is not known what causes the condition in the remaining cases. It is suspected that the condition might be the result of certain environmental factors combining with genetic factors.
