Which symptom is unique to amyotrophic lateral sclerosis (als) and is not observed in multiple sclerosis (ms)?
Nonamiya [84]

ALS is a rapidly progressive and fatal neuromuscular disease. MS is a scarring and hardening of the sheath around the nerves in the brain, spinal cord, and optic nerve. MD is a muscular disorder with specific kinds of MD involving different muscles in the body. MD is almost exclusively hereditary

<h3>What is Amyotrophic lateral sclerosis (als) ?</h3>

The motor neurons steadily degrade and eventually die as a result of ALS. The brain, spinal cord, and all the muscles in the body are connected by motor neurons. When motor neurons are destroyed, they stop communicating with the muscles, which prevents the muscles from working.

  • Five to ten percent of all ALS cases are familial, meaning the patient gets the illness from a parent. Typically, only one parent needs to have the disease-causing gene to have familial ALS.
