On ALS: Notes:
 * ALS: stands for Amyotrophic Lateral Sclerosis
 * Usually fatal
 * Is a Neurodegnerative Disease
 * Sometimes called Lou Gehrig's Disease
 * Affects the nerve cells in the central nervous system (that control voluntary muscle movement)
 * Causes muscle weakness and atrophy throughout body
 * Upper and lower motor neurons storp sending messages to muscles
 * Muscels grow weak
 * Develop Fasciculations (twitches)
 * Patient may ultimately lose the ability to initiate and control voulantary movement except for eyes
 * First symptoms are small, and usually overlooked
 * First symptoms are weakness, and possible muscle atrophy
 * Followed by twitching, cramping, or stiffness of affected muscels.
 * Slurred and nasal speech
 * Twitching and cramping is the result of a dying muscle.
 * Parts of body affected by early symptoms depend on which motor neurons in the body are damaged first
 * 75% experience "limb onset"
