Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually lead to their death. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary muscle action progressively affected, patients in the later stages of the disease may become totally paralyzed. ALS was first described in 1869 by French neurologist Jean-Martin Charcot, but it wasn’t until 1939 that Lou Gehrig brought national and international attention to the disease when he abruptly retired from baseball after being diagnosed with ALS. Most commonly, the disease strikes people between the ages of 40 and 70, and as many as 30,000 Americans have the disease at any given time. ALS has cut short the lives of other such notable and courageous individuals as Hall of Fame pitcher Jim “Catfish” Hunter, Senator Jacob Javits, actors Michael Zaslow and David Niven, creator of Sesame Street Jon Stone, television producer Scott Brazil, boxing champion Ezzard Charles, NBA Hall of Fame basketball player George Yardley, pro football player Glenn Montgomery, golfer Jeff Julian, golf caddie Bruce Edwards, British soccer player Jimmy Johnstone, musician Lead Belly (Huddie Ledbetter), photographer Eddie Adams, entertainer Dennis Day, jazz musician Charles Mingus, composer Dimitri Shostakovich, former vice president of the United States Henry A. Wallace and U.S. Army General Maxwell Taylor.
