It all began in your brain, the starting point for an important chain of communication. Your brain ordered nerve cells, to activate muscles in your hand and fingers. In this instance, your muscles responded, and your fingers moved. In a person afflicted with Amyotrophic Lateral Sclerosis (ALS), there is a break in the chain of communication. The motor neurons degenerate and die. Because of the lack of motor neurons, the brain cannot communicate with the muscles, and voluntary muscle movement is no longer possible. Because the muscles are no longer used, they too begin to degenerate and weaken causing a wide range of disabilities. II. ALS is a neurological disease that attacks ones muscles, approximately 5,600 people are diagnosed with ALS each year. III. ALS, also known as Lou Gehrig’s, has claimed an estimated 790,000 lives since the disease was discovered. IV. The symptoms of the disease are obvious and painful as the disease progresses quickly throughout its victim’s body.
