Multiple Sclerosis is a
demyelinating disease of the central nervous system. MS effects the substance known as myelin which
protects the nerve fibers that carry critical neurological messages to different parts of
the body. For unknown reasons myelin is attacked and during the repairing
process scar tissue known as plaque forms. These plaques harden and begin to interfere
with the flow of information from nerve impulses. Consequently, symptoms of
MS are dependent upon the exact location of these plaques. For example, when
an area of demyelination occurs in the cerebellum, the area of the brain
that is responsible for making coordinated movements, coordination becomes impaired.
Because the area of scarring dictates the symptoms, no two cases of MS are
exactly alike and symptoms vary considerably from one individual to another.
Symptoms of MS can
include: tingling sensations, numbness, muscle fatigue, poor coordination,
blurred vision, dizziness, pain, bladder and bowel incontinence, spasticity,
contractures, difficulty with speech and swallowing, sexual dysfunction or
paralysis. These symptoms may occur in any combination, may come and go, and may vary from
very mild to very severe.
MS is not contagious and is not a
mental illness. It is more common among women than men, and symptoms usually surface
between the ages of 20 and 45.
At present there is no
known cause or cure. However, there is medical treatment available to slow
the progression of the disease, treatment to minimize and control specific
symptoms, and therapies to minimize discomfort and inconvenience. |
