12 Muscle Twitching Causes You Should Know (Common Triggers)

Amyotrophic Lateral Sclerosis

Wasted or dead neurons or motor nerve cells are not helpful in the body since they can no longer give signals through the body from the brain. This condition is known as an amyotrophic lateral syndrome or ALS. It is a persistent disease that targets the nerve cells in the central nervous system. This condition affects the controllability of the muscles. 

ALS damages the nerves that send messages to the voluntary muscles. It only targets the motor neurons, which is why walking, talking, and even eating is difficult in patients with ALS. It affects the motor neurons or nerve cells by deteriorating and eventually killing them. Since these motor neurons are damaged, they stop sending signals to the muscles; hence patients with ALS experience muscle weakening and twitching. At first, the patients may feel weak. However, after a while, ALS will consume and affect the muscles more aggressively, resulting in involuntary movements and more noticeable twitching.
