ALS

life science Maturity 11-13 Next article →

ALS is a sickness that affects the body. The full name is Amyotrophic Lateral Sclerosis. It is a disease that targets motor neurons. These are special cells that help you move. They send signals from your brain to your muscles. In ALS, these cells stop working. This makes the muscles get very weak.

This sickness works in a specific way. First, the motor neurons begin to fail. Because they fail, they cannot send signals. The muscles do not get the messages they need. This causes the muscles to shrink and weaken. It can make it hard to walk. It may also make it hard to talk.

People with ALS face many hard jobs. They might find it tough to swallow food. The sickness can also affect breathing. This happens because the breathing muscles get weak. Some people have a type called familial ALS. This type runs in families. Other cases are called sporadic ALS. These cases have no family link.

Scientists study this disease to help people. They look for ways to slow it down. They want to learn how it works. Researchers study both types of ALS. They look at the family links in sporadic cases. They also look at the genes in familial cases. Every new fact helps doctors.

Think about how your body moves every day. You use muscles to run and jump. Your brain tells those muscles what to do. ALS breaks the link between the brain and muscles. It is like a broken wire in a machine. The machine still has power, but the signal stops. Learning about ALS helps us understand the body.
