What Causes Multiple Sclerosis?

Despite being relatively well-known, there is often some doubt surrounding the causes of multiple sclerosis. According to the National MS Society, there are various factors which could contribute to someone developing MS.

Multiple sclerosis, or MS, is a disease that can affect the brain, spinal cord and optic nerves. The effects vary from person to person, from mild symptoms that require little treatment and allow the patient to lead a reasonably normal life, to more severe symptoms requiring more care.

But what exactly causes multiple sclerosis?

The cause can sometimes be immunological. MS is caused when the body’s immune system attacks something called myelin, a protective material found on the outside of nerve fibres. The damage MS causes to this material damages the nerve fibres, meaning your brain cannot send signals through your body the way it wants to.

Some specialists believe it’s the environment. Statistical evidence suggests that there are a higher number of MS cases in countries further away from the equator. Such studies also suggest that if a person born in a high-risk area moves to a lower risk area before the age of 15, that they assume the risk of the new area. This could be related to vitamin D intake. Countries closer to the equator typically have more hours of sunlight, meaning that the inhabitants of these areas naturally produce more vitamin D, which helps to support and protect the immune system against immune disease such as MS.

Smoking is also thought to increase the risk of developing MS, and exacerbates the severity and the progression of the disease.

In the beginning of our lives, our body is exposed to a number of disease-causing bacteria, such as measles, canine distemper, human herpes virus-6 and chlamydia pneumonia. All of these bacteria either have been or are being investigated to figure out whether exposure to can trigger the development of MS.

Although MS is not a genetic disease, there is an increased risk of developing the disease if a relative like a parent or sibling is already affected. Some research also suggests that people can be born with a genetic predisposition that can act as a catalyst for a immune response when put into contact with certain environmental factors.

    The conclusion from this article is that we do not know what causes MS.

    But one fact is very useful in finding and accepting a treatment for MS; MS is more common the farther from equator you live. Norway, Canada and Argentina has a higher frequency of MS patients in the population than Ecuador and the Philippines. Vitamin D and the sun seems to play a major role in the development and treatment of MS.

    That was the starting point for the treatment for Autoimmune Diseases developed by Professor Coimbra. The very respected Coimbra protocol. http://www.coimbraprotocol.com

    Resistance in the body to benefit from vitamin D led Dr Coimbra to increase the dosage of vitamin D until the PTH level was reduced to its lower normal range. Then the immune system was starting to act as normal and stop its autoimmune reactions. On MRI, you can see the lesions in the brain reduced and fade away. Patients get their balance back, their eyesight back, their strength back and the fatigue disappear. Life gets normalized. For some it takes a few months, others need to follow the protocol for 15 months or more to see the change. But eventually it comes to almost everybody.

    As far as I know, no other protocol or medicine have ever given the same results. And the treatment is both cheap and safe according to the patients. https://www.facebook.com/groups/vitamindprotocolnorthamerica
    So even if we do not know what exactly causes MS, there is a very powerful, cheap and safe protocol that works in fighting MS.

    Yes I too believe in vitamin D I take for MS. If I hadn’t started on vitamin D I know I wouldn’t be able to walk by now. I still have tinnitus and spinal problems but ime convinced about this vitamin. I take it all through winter days and ease off when summer comes. You can get it in a spray which I use. Wouldn’t be without it.

      That is great to hear Marie! Sounds like you have found a good way for you to have VitD on a regular basis that works for you. Keep it up!

    My MS started arround 2010, about this time I began using Ylang Ylang as a scent, daily (as my new lady liked it ). I am now descovering that the oil can be a stimulant to the immune system. Could Ylang Ylang be a caues of myMS ?
