MULTIPLE SCLEROSIS 2
Multiple Sclerosis
Multiple Sclerosis occurs when the myelin layers covering our nerve fibers are attacked,
and destroyed by our immune system. This disease can impair our ability to balance, cause
blurry vision or blindness, weakens the body providing it with no strength, and affects our
sensation. The onset of symptoms can occur between 20 and 40 years old, and affect women
more than men. The family history of having MS will increase a person’s chance of developing
this autoimmune disorder as they get older (Davidson, Slomski, & Cataldo, 2012).
How it affects the nervous system
Multiple Sclerosis is a disease of the nervous system, and the damage caused to the
myelin sheath is a slow progression. The reasons why our immune system attacks the myelin is
still unknown. Some evidence has led to the belief that genes, viruses or even environment can
play a role in MS.
Myelin is responsible for assisting our brain and the rest of the body inefficient
communication. As the layer is being destroyed, scar tissue is formed. This type of scar tissue is
called plaques, which further prevent signals from passing between the body and brain. Since the
plaques are unpredictable and control what symptoms are shown, it is hard to distinguish any
specific pattern on how the disease is progressing.
Sometimes in patients with the primary progressive pattern have remission or little
improvement of symptoms, which is seen more often in people who are older. The secondary
progressive pattern starts out with a patient relapsing, then the progression of symptoms
progresses at a steady pace.
When nerve pathways and optic nerves are involved in the deterioration, the symptoms
can range from double vision to blindness. There are cognitive changes as well, even though
