ALS (amoytrophic lateral sclerosis) is a disorder that directly affects nerve cells that control movement. These nerve cells send impulses from the brain to control movement. When these nerve cells can no longer send messages for movement, much of the tissue involved with movement begins to atrophy (decline).
