A continuation from last week. Multiple Sclerosis (MS) is classified as an autoimmune disease of the central nervous system (brain, spinal cord, and optic nerves). Symptoms of MS are unpredictable and vary greatly from person to person, and can fluctuate within the same person from one time to the next. People can experience symptoms such as extreme fatigue, lack of coordination, weakness, tingling, impaired sensation, vision problems, bladder problems, cognitive impairment and mood changes.
