'''Lou Gehrig's Disease''', medical term known as Amyotrophic Lateral Sclerosis (ALS) is an incurable disease of the muscles. As nerve cells die, the muscles they control stop acting and reacting correctly. Eventually, ALS weakens muscles, including muscles used for breathing, until they become paralyzed. Most people with ALS die of respiratory failure. <ref>[http://www.ucsfhealth.org/adult/medical_services/neuro/lou_gehrigs_disease/conditions/als/signs.html Lou Gehrig's Disease (ALS)] Univ. of Ca.
