Mental disease or disorder

The large number of diseases that affect the brain, I chose Amyotrophic Lateral Sclerosis or better known as ALS, is a neurological disease that causes death of neurons that control voluntary muscles.

ALS is characterized by stiff muscles, muscle twitching, and gradually worsening weakness due to muscles decreasing in size. What eventually causes difficulty in speaking, swallowing, and finally breathing.

Despite the fact that ALS is the third most common neurodegenerative disease in the world, affecting two or three of every 100,000 inhabitants, generally people between 40 and 70 years old, its origin is unknown, it has no treatment and it has a life expectancy of three years. Although there is a medication called RILUZOLE, it can extend the patient's life expectancy from two to three, just as non-invasive ventilation can result in better quality and longer life.

I chose it because I had heard about this disease before, several well-known people had this disease like Stephen Hawking and, Jason Becker, but I did not know what it really was  and I thought I could understand the causes of this disease, but there are still many things that are not yet known with certainty that it causes some neurodegenerative diseases
