The nervous system is the most important system in the body. It transmits impulses to and from the brain. Disruption of the nerve cells and fibers that transmit the messages severely impairs the body’s ability to carry out complex function. Once a disruption occurs‚ one may never recover and neurological function will steadily degrade. Multiple Sclerosis is a disease that disrupts this network. Multiple Sclerosis (MS) is the most common disabling neurological disease in young adults between 20 and
