Multiple Sclerosis
Multiple
sclerosis is an illness that involves spinal
cord and the brain. This illness progresses
with time leading towards disabling. There is
a sheath composed of myelin that is a fatty
substance. This sheath functions to provide
insulation by surrounding nerve cells.
Nerve impulses are transmitted
through this sheath. When some damage or inflammation
occurs to this sheath, multiple sclerosis occurs.
Nerve impulses are slow down or disrupted. Some
areas of scarring are left as a result of this
damage of inflammation called sclerosis. The
term multiple sclerosis plaques is used to define
the areas where scarring and damage to myelin
sheath have occurred.
When disruption in the nerve impulses
occurs, many problems may be encountered. Sensation,
vision and movements related to body can be
badly affected. These symptoms are not permanent.
They occur in the form of series of episodes.
When these symptoms come, condition worsens
and it is called relapses.
And when symptoms are improved,
conditions become better and it is called remissions.
Multiple sclerosis can affect patients for many
decades too with the symptoms coming and going.
When the attacks are occurred, this illness
becomes worse.
Causes
There have been many decades since
the scientists were trying to find the exact
reason of the occurrence of multiple sclerosis.
Now the scientists have come to know that when
the immune system of a patient does not go well
with the body and attacks its own body, then
multiple sclerosis occurs.
So it is said that multiple sclerosis
is an autoimmune disease. In multiple sclerosis,
the immune system of the body attacks the myelin
sheath surround the nerve cells and thus destroy
their functions.
It is said that either a viral
infection or emotional or physical stress could
give rise to multiple sclerosis. Scientists
have not predicted the duration, timing and
damage that is resulted due to the attacks of
multiple sclerosis.
This disease is most commonly found
in young people especially among those that
are located in temperate climate regions. Women
are more likely to have this illness. It seems
that this illness is transferred through genes
but no single gene has been identified yet that
could be the cause of multiple sclerosis. Scientists
believe that multiple sclerosis occurs due to
combined action of several genes.
Symptoms
There are many symptoms of multiple sclerosis
that depend on the affected areas of the spinal
cord and brain. Following are the symptoms of
multiple sclerosis:
- Double or blurred vision happens in multiple
sclerosis. Sudden loss of vision also results.
- Clumsiness is also a symptom that usually
occurs on one side when one gets multiple
sclerosis.
- The walking pattern unsteady.
- Patients start losing coordination.
- Usually a hand starts trembling.
- Patients complain of extreme tiredness.
- Expressions of weakness, pain and numbness
are found on face.
- Patients lose control on their bladder.
- Patients complain of feeling constriction,
numbness and tingling in their body especially
in the legs and arms.
- Patients feel heaviness or weakness in
their legs or arms.
Diagnosis
Multiple sclerosis should be considered if a
person complains of symptoms that show disorder
of spinal cord or brain or both of them. These
symptoms are most commonly found in people younger
than 40 years. But this disease can occur in
people of ages between 40 to 60 years. If a
person complains of losing vision or blurring
or doubling of vision, extreme weakness, change
in walking pattern, loss of body coordination
etc then one should inform the doctor and the
doctor should consider these symptoms related
to multiple sclerosis.
Magnetic resonance imaging (MRI)
scan of the spinal cord and brain should be
ordered for the confirmation of the diagnosis
of multiple sclerosis. Ophthalmologist should
also be consulted for the examination of eye.
Prevention
There is no way found yet that could prevent
multiple sclerosis.
Treatment
No cure for multiple sclerosis is found yet. |
