The patient's immune system does that by its response to the virus. People who develop MS have an inherited immune response to the virus. This response causes their bodies to mistakenly produce antibodies that actually attack the nerves. The whole nerve is not involved. Incidence MS is more common in temperate zones than in the tropics and subtropics.
Women are slightly more likely to get the disease than men.
The actual extent of MS is difficult to estimate, however, because mild cases may not even be reported to doctors and may be misdiagnosed when they are. One estimate is that 350,000 Americans have the disease. Usually MS patients suffer their first attack between the ages of 20 and 40 years old. Symptoms you are likely to notice The disease usually begins with tingling, numbness , or weakness in an arm or leg, or in one spot somewhere else on the body. If an arm is affected, you may drop items more often than normal because your muscles are unexpectedly weak.
