As a result of attacks on the nervous system, the nerves stop functioning properly, which leads to the symptoms of Multiple Sclerosis. Any part of the central nervous system could be affected, leading to the many different symptoms. Patients could get numbness, weakness, tremor, loss of vision, double vision, difficulty with walking and loss of balance, stiffness in the arms and legs, difficulty swallowing, slurred speech, fatigue, bowel and bladder incontinence, impotence, difficulty with memory and concentration, and other neurological symptoms. The symptoms tend to occur rapidly within hours and days often mimicking a stroke. Unlike a stroke however, at least initially, the symptoms of MS improve within days to weeks.
