Lou Gehrig's disease

Lou Gehrig's disease is a disorder that's also called amyotrophic lateral sclerosis or ALS. The official name comes from these Greek words:So, amyotrophic means that the muscles have lost their nourishment. When this happens, they become smaller and weaker. Lateral means that the disease affects the sides of the spinal cord, where the nerves that nourish the muscles are located; and sclerosis means that the diseased part of the spinal cord develops hardened or scarred tissue in place of healthy nerves.
