Amyotrophic lateral sclerosis (ALS) – Introduction, causes, and types
Amyotrophic lateral sclerosis (ALS) is a motor neuron disease. It attacks the nerve cells that are used for involuntary muscle actions which are also known as motor neurons. There are actions that we can control, such as those in the legs, arms, and face. Motor neurons are present in the spinal cord and brain. As Amyotrophic lateral sclerosis (ALS) progresses, these cells tend to degenerate and then eventually die. They stop sending messages to the muscles. The brain is, therefore, no longer able to control voluntary movements. Also, the muscles weaken and eventually waste away. Ultimately, Amyotrophic lateral sclerosis (ALS) affects all the voluntary muscles. This means that the person affected no longer has control over their arms, legs, and face. Some people diagnosed with Amyotrophic lateral sclerosis (ALS) manage to live more than ten years. However, most people with Amyotrophic lateral sclerosis (ALS) live between three to five years after experiencing their first symptoms. Amyotrophic lateral sclerosis (ALS) is said to affect between two to five people in every 100,000 in the world. The famous physicist Stephen Hawking was diagnosed with Amyotrophic lateral sclerosis (ALS) during his youth. Now, being over 70 years of age, he is considered as one of the greatest scientists for his achievements.
