Lou Gehrig's disease is a disorder that is also called amyotrophic lateral sclerosis or ALS. The official name comes from the following Greek words - "a" for without, "myo" for muscle, "trophic" for nourishment, "lateral" for side (of the spinal cord), "sclerosis" for hardening or scarring. 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. ALS is often called Lou Gehrig's disease after Lou Gehrig, a hall-of-fame baseball player for the New York Yankees who was diagnosed with ALS in the 1930s. People in England and Australia call ALS “Motor Neurone Disease (MND)”. The French refer to it as “Maladie de Charcot”, after the French doctor Jean-Martin Charcot, who first wrote about ALS in 1869. Lou Gehrig's disease damages motor neurons in the brain and spinal cord. Motor neurons are nerve cells that control muscle movement. Upper motor neurons send messages from the brain to the spinal cord, and lower motor neurons send messages from the spinal cord to the muscles. Motor neurons are an important part of the body's neuromuscular system. The neuromuscular system enables our bodies to move and is made up of the brain, many nerves, and muscles. Things that we do every day — like breathing, walking, running, lifting stuff, and even reaching for a glass of water — are all controlled by the neuromuscular system. Over time, Lou Gehrig's disease causes the motor neurons in the brain and spinal cord to shrink and disappear, so that the muscles no longer receive signals to move. As a result, the muscles become smaller and weaker. Gradually the body becomes paralyzed which means that the muscles no longer work. However, someone with ALS, even at an advanced stage, can still see, hear, smell, and feel touch. The nerves that carry feelings of hot, cold, pain, pressure, or even being tickled, are not affected by Lou Gehrig's disease. The parts of the brain that allow us to think, remember, and learn are also not affected by the disease. Although this disease can strike anyone, it is extremely rare in children. According to the ALS Association, most people who develop Lou Gehrig's disease are adults between 40 and 70. Only 2 out of every 100,000 people will get the disease each year. Because it is not contagious, you can't catch ALS from someone who has the disease. According to the ALS Association, about half of all people with ALS live at least 3 years after they find out they have the disease, and 20% (or 1 in five) live 5 years or more. As many as 10% will survive more than 10 years. Stephen Hawking has been living with Lou Gehrig's disease for about 40 years — ever since his diagnosis at age 21. He is the most famous long-term survivor of the disease. Living with Lou Gehrig's disease is physically difficult, but it is reassuring to know that the mind is not affected. People with the disease can think as clearly as ever, are able to maintain relationships with friends and family, and should be treated respectfully and normally. Communication can be difficult because the disease affects the person's breathing and the muscles needed for speech and arm movement. With patience, the families of patients with ALS can learn to communicate effectively with their loved one. Researchers continue to study ALS as they try to understand why it happens, and how the disease damages the motor neurons in the brain and spinal cord. As they learn more about the disease, researchers can continue to develop new and better treatments.
