What is MS?

Multiple Sclerosis (MS) is an disease where the protective covers for the nerves breakdown.
The immune system attacks the protective sheath - myelin - that are wrapped around the fiber
nerves to protect them. As the nerve cells become damaged, this interupts communication between
the brain and the body.

by MS.
