8. Myths and Facts about Multiple Sclerosis
Myth: There is no hope if diagnosed with Multiple Sclerosis
Fact: Though there is no cure for multiple sclerosis, there are
treatments which vary in effectiveness with each individual. There
are, at present, six drugs that have shown some ability to modify
the disease.
Myth: Multiple Sclerosis is a deadly disease.
Fact: There are available treatments that can help the person with
this disease lead a normal, active life. Deaths are only the result of
untreated complications such as kidney dysfunction and when
severe depression leads to suicide.
Myth: Multiple Sclerosis will ultimately land you in a wheelchair.
Fact: Early detection, proper therapy and treatment can make life
much easier for a person with multiple sclerosis. Many people use a
mobility aid, such as a wheelchair or powered cart, to conserve
energy for other activities.
Myth: People with Multiple Sclerosis should not be parents.
Fact: Multiple Sclerosis will do no harm to pregnancy and childbirth.
In many women, the symptoms are negligible during this period.
However, the risk of an attack is increased in the first six months
post delivery. There is a very small chance of the child inheriting the
problem of multiple sclerosis from the mother.

Myth: People with Multiple Sclerosis should avoid working.
Fact: Many people still lead a very normal life despite their multiple
sclerosis. There is not enough evidence to prove that normal stress
and work pressures have any effect on multiple sclerosis. As many
as 30% of Multiple Sclerosis patients are still working full-time
without much trouble, even after years with the disease.
Other Facts about Multiple Sclerosis
1. Multiple Sclerosis may be malignant in rare cases and prove fatal.
2. Until the year 1993, there were no medicines, but there are
currently six approved drugs that are sometimes effective in
controlling the disease.
3. The chances of children inheriting the disease from their parents
are between 1% and 5%.
4. It affects 2.5 million individuals worldwide.
5. Canada has a significant risk of Multiple Sclerosis. More than
50,000 Canadians have Multiple Sclerosis.
6. Twice as many women as men suffer from this disease.
7. Multiple Sclerosis mostly strikes people between the ages of 20
and 40.
8. The symptoms of this disease vary. They may include blurred
vision, loss of balance, extreme fatigue, stiff muscles as well as
bowel and bladder difficulties.

Part-III: Causes, Incidence, and Risk Factors
9. Causes of Multiple Sclerosis
The main cause(s) of multiple sclerosis in an individual are still
being studied. There has no been a particular gene found that is
responsible for causing this disease. But, research indicates that
people with some genetic susceptibilities have more chances of
developing this disease when there are environmental conditions
that are favorable for a virus or toxin attack.
It may be that viral infection, environmental factors, hereditary
factors, or a disorder of the immune system may be causes of
multiple sclerosis. Studies also indicate that it might be an
individual’s unique reaction to an infection by some substance or a
reaction within the nervous system that causes their body’s own
defenses to attack it.
Genetic Factors
Genetic factors could be responsible for making a person susceptible
to multiple sclerosis. But, the risk of someone inheriting all the
genetic factors responsible for multiple sclerosis is thought to be
less than 5%. Research continues in this field to identify the exact
genes responsible for multiple sclerosis.

Infectious Agents
Viruses top the list of suspects for causing autoimmune response in
people who are genetically susceptible to multiple sclerosis. Factors
that favor this conclusion include:
1. The geographical distribution of the disease: The number of
multiple sclerosis-infected people is more as one moves away from
the equator in either direction.
2. Some studies indicate that multiple sclerosis might be a sexually
transmitted infection. Countries with some sexual freedom seem to
have a higher degree of multiple sclerosis in their population while
the disease is close to negligible in countries with traditional
cultures.
3. Viral similarity to myelin: Some viruses are quite similar to
myelin. This similarity may cause confusion to the immune system
and make the T-cells attack the body protein rather than viral
antigens. There are not sufficient results from studies to confirm
this as a prime trigger.
Three major suspects are:
1. HHv-6 or Herpes virus 6, a form of herpes virus that causes
rosella, a benign children’s disease.
2. Chlamydia pneumonia, a bacterium that causes constant
inflammation in small vessels.
3. Epstein-Barr virus, the virus that causes mononucleosis.
What causes multiple sclerosis in an individual is still a debatable
issue but the most widely accepted theory is that of an autoimmune

disorder, where the components of the immune system fail to
recognize the normal body tissues and start attacking them as if
they were invaders.

10. Cognitive Impairment in Multiple Sclerosis
What is cognitive impairment?
Cognition means thinking and includes our ability to pay attention,
learn, solve, express, and remember. These functions can be
impaired by multiple sclerosis.
Research led to the fact that this illness can affect the way the mind
works, particularly the cognitive power of the brain.
Almost one-half of people suffering from multiple sclerosis have
some cognitive impairment. As much as 80% of the people with this
disease show the signs of moderate symptoms, such as having
some difficulty when remembering a list of items to buy or
performing mental activities in a distracting environment.
The rest may suffer from a more severe condition and may even be
unable to work or do some of their daily activities.
Causes of Cognitive Impairment in Multiple Sclerosis
Stress, anxiety and depression can lead to us being unable to
remember or pay attention. The cognitive dysfunction in this illness
is due to the changes in the brain. Multiple sclerosis produces
lesions that affect the electrical impulses transmitted across the
nerve cells. A person with just a few lesions may not experience any
cognitive dysfunction but someone with many lesions could
experience marked cognitive dysfunctions.
Diagnosis of Cognitive Impairment
With the help of neuropsychological examination, medical
practitioners can diagnose cognitive impairment. A
neuropsychological examination is a series of cognitive tests.

The results are compared to the results of a healthy individual of
same age and similar physical attributes.
Is Cognitive Impairments Inevitable with Multiple Sclerosis?
Cognitive dysfunction may occur very early in many people with
multiple sclerosis, but many people may have no such problems at
all. But, there is little relationship between the degrees of physical
disability and cognitive impairment.
Treating Cognitive Impairment in Multiple Sclerosis
At present, there are no medications for cognitive problems in
Multiple Sclerosis. Research is continuing to find ways of improving
memory functions.
Medications to Reduce Cognitive Impairments
At present, FDA has approved three medicines for treating patients
with Multiple Sclerosis; Avonex, Betaseron, and Copaxone.
Apart from medicine, there are cognitive retaining programs that
are available in most medical centers. There are exercises for the
brain, like doing crossword puzzles, reading, and other brain
stimulating programs. That may make a lot of difference to the
patients’ cognition power.

11. Effects of Multiple Sclerosis
The Invisible Symptom Factor
The effects associated with multiple sclerosis are numerous.
Fatigue is frequently a symptom that brings much distress to
patients. Fatigue may occur in the person who is not showing any
signs of illness. Others often judge the fatigue in multiple sclerosis
as mere laziness and this can cause misunderstanding.
This disease is not fatal, but it can reduce the patient’s life by six or
seven years. About half the people with multiple sclerosis die from
the various effects of the disease.
Depression may increase any suicidal tendencies in the patient.
If your loved one, or you, suffers depression then you must seek
professional help.
Specific Effects of Multiple Sclerosis
1. Fatigue: Fatigue is one of the debilitating and common
symptoms of multiple sclerosis.
2. Loss of mobility and spasticity: Almost all people with
multiple sclerosis experience some loss of mobility in them.
Spasticity is one of the main symptoms of this disease. It is more
severe in the legs and torso.
3. Bowel and Urine dysfunction: There are chances of
constipation or fecal incontinence in a person with multiple sclerosis.
Urinary dysfunction occurs in almost two-thirds of people suffering
from multiple sclerosis. Many patients have difficulties controlling
when they urinate.

4. Difficulty in swallowing: Many patients of this disease
experience difficulty swallowing and even chewing their food.
5. Lung problems: The weakening of muscles can create breathing
problems and makes coughing more difficult for the patient. The
patient may develop pneumonia and other lung complications.
6. Effects of cognitive impairment: At least 50% of people with
multiple sclerosis notice changes in their mental condition. This is
often problems with understanding, remembering, focusing, solving
problems and processing information in the mind as quickly as
before.
The following effects are associated with multiple sclerosis:
1. The multiple sclerosis patient often loses some of the quality
of their eyesight.
2. The patient may suffer from some paralysis.
3. The patients lifespan may be shortened by about six years.
4. Patients often complain of weakness in their muscles.
5. Some patients complain of hearing loss.
6. This disease may also cause involuntary twitching of muscle
fibers in patents’ limbs and rapid increase in the number of white
blood cells.
7. A few people suffer from fits.
8. There may brain failure in some instances.
9. Gliosis (swelling and scarring of astrocytes – important cells
in the patient’s brain and spinal cord) and Pseudobulbar palsy

(difficulties with chewing and swallowing as well as emotional
outbursts) are also sometimes suffered by Multiple Sclerosis
patients.
10.
Multiple sclerosis can affect the cerebellum, a slightly
cauliflower-shaped part of the brain at the top of the spinal
column and this causes loss of co-ordination in the patient’s
movements.
11.
Damage to the nerves that help control the bladder
cause urinary problems.
12.
Tingling or burning sensations that are probably due to
nerve damage (Paresthesia) and constipation are associated
with multiple sclerosis.
13.
Dizziness
14.
Taste disturbance
15.
Eye problems, including Optic neuritis.

12. Risk Factors for Multiple Sclerosis
These risk factors may indicate that someone has a significant
chance of getting multiple sclerosis. They do not definitely lead to
multiple sclerosis.
The risk factors or the conditions for multiple sclerosis are:
Environmental Susceptibility in multiple sclerosis
The US, Europe, Soviet Union and Canada had a prevalence of
multiple sclerosis in the mid 20th century. The number of multiple
sclerosis-infected people is more as one move away from the
equator in either direction. The study made in accordance with sex,
the disease has high prevalence among the women.
Genetic Susceptibility in MS
Twin studies that show a higher rate of multiple sclerosis present in
primary relatives indicate that genetic factors may be responsible
for up to 30 percent of multiple sclerosis.
Vitamin D and Sunlight
Vitamin D is necessary in the body; it helps cell maturation and the
responses of the immune system. Vitamin D, with the help of
sunlight, is converted to an active form. When the person is
suffering from multiple sclerosis, the body mistakenly produces anti-
inflammatory cytokines, Th2 cells and Th1 cells that reduce the
vitamin’s essential beneficial activity. Deficiency of vitamin D and
less sun exposure may increase the chances of multiple sclerosis or
change the course of the disease.

It only takes 15 minutes per day outside to get enough vitamin D
from the sun. Some milk companies add Vitamin D to their milk.
Smoking and MS
There is evidence to indicate that smoking increases the risk of
multiple sclerosis. Smoking seems to worsen the symptoms of
multiple sclerosis. Multiple sclerosis is high amongst smokers.
Viral Triggers and MS
Viral infection may be the most important trigger of multiple
sclerosis. A prevalent childhood infection may lead to multiple
sclerosis in adolescence.

13. Genetic Factors for Multiple Sclerosis
Genetics may have a major role to play in determining multiple
sclerosis. There is a higher chance of developing multiple sclerosis if
the disease exists in family members. That chance is even higher if
the person suffering is your first-degree relative; brother, sister or
parents.
There has been no identification of a particular gene causing
multiple sclerosis. Researches are continuing in this area.
Some populations, like Gypsies, Eskimos, and Bantus, may never
develop multiple sclerosis. Similarly, Native Indians, South
Americans, Japanese and other Asians have less chance of getting
multiple sclerosis.
It is unclear whether this disease is mostly due to genetics or
environments.
Twin studies are the classic method of determining whether the
genes have any influence on a disease. The concordance rate is a
measure adopted in genetics that refers to the presence of similar
traits in both members of a pair of twins or set of individuals.
Research indicates that, though genes play a role in multiple
sclerosis, the maximum effect is possibly only up to 30%.
In the general population, the occurrence of multiple sclerosis is
about 0.1%. This figure contrasts to its recurrence in families
among primary relatives: Parents 3%, daughters 5% and sons 1%.
The rate in the next level of relatives is aunts and uncles 2%, nieces
and nephews 2%, and first cousins 1%.

14. Nutritional Factors and Multiple Sclerosis
Nutritional factors play an important role in controlling multiple
sclerosis:
1. You must take nutrients that will help your body to restrain the
autoimmune reactions.
2. You should not eat food that lets your body activate the immune
system against yourself and creates autoimmune reactions.
Two forms of nutrients that are believed to help suppress immune
system problems in the central nervous system are vitamin D and
omega three essential fatty acids. However, there are a shortage of
these in the environment and in many people’s diets. So, the body
of the person suffering from this disease can become deficient.
If you also suffer from multiple sclerosis, you should ask your
medical practitioner about increasing your intake of vitamin D and
omega three oils. An increased intake of these important nutrients
may help you to suppress the autoimmune reactions of your body.
According to some studies, our body needs a supply of 4000-5000
IU vitamin D each day to function well. The sun is the main source
for vitamin D and people living in the colder regions may not get
enough directly from sunlight.
Consult your doctor and check your local supermarket or drugstore.

Always consult your own medical practitioner before changing your
diet or other habits significantly.
Some people recommend the following measures:
1. Take a supplement of 4000-5000 IU vitamin D each day.
2. Eat fish three times a week if there are no medical reasons
for caution (pregnancy, high mercury content etc)
3. Have a spoonful of flax oil each day. (omega 3)
4. Avoid dairy products and gluten grains like wheat, rye,
barley, etc.
5. Avoid legumes and yeast.
6. Substitute olive oil as a fat supply in your diet
7. Reduce your intake of red meat and saturated fat.
8. Take supplements that might improve your health.

Part-IV: Impact of Multiple Sclerosis
15. Multiple Sclerosis and Your Emotions
Common Emotional Reactions
A person suffering from multiple sclerosis is likely to undergo some
emotional turmoil regardless of the form of multiple sclerosis. There
is a sense of disbelief, fear, anger, depression, and guilt among
almost all the people that are diagnosed with multiple sclerosis.
Fear or Apprehension: Fear is very common amongst the people
suffering from multiple sclerosis. The fear of adjustment and dealing
with their unpredictable condition through all their life makes this a
fearful disease. Besides the illness, the fear of losing control over
oneself seriously affects many.
Denial: Denial is the normal initial reaction by many people who
have multiple sclerosis. Denial can cause a person to not take
necessary action that is imperative to start dealing with this
disease.
Grieving: People with multiple sclerosis should grieve if they feel
the need to. This grieving may help them adjust to their situation
and their grieving should be accepted by family and friends.
Guilt: A feeling of not being able to carry on with daily chores
brings a sense of guilt in people with multiple sclerosis. Children
often intensify the guilt feelings of the parent. There may be no
expression of fear and anger, but the feeling is always there. So, it
should be a joint effort by every member in the family to let the
person cope with it. Feelings of guilt heighten when friends and
relative
