Ms is a progressive central nervous system disorder that affects the function of your brain and spinal cord. 


It occurs when the immune system treats myelin sheath as a threat, therefore attacking the cells that produces it and the Myelin sheath itself.

This can alter communication between the brain and the rest of the body.

The scars left on the nerves inside the sheath after the attack is called sclerosis.

What causes MS is not known, but scientist suggest the factors below contributes in developing MS.

  1. Genetics: MS is not hereditary but researchers believes abnormalities in some genes increases your chances of developing it. 
  2. Environmental – Researchers has linked lack of vitamin D in the body increases your chances in developing MS.
