Multiple sclerosis, (MS), is a long lasting disease that can affect your NERVE ON BRAIN, spinal cord, and the optic nerves in your eyes. It can cause problems with vision, balance, muscle movement, and other basic body functions.
(MS )happens when your immune system attacks a fatty material called myelin on the nerve, which is around your nerve fibers to protect them. Without this outer shell, your nerves become damaged. Scar tissue may form.
damage case your brain can’t transfer signals through your body correctly. Your nerves don't work as they should to help you in movement and feel. As a result, you may have problems like:
Trouble walking
Feeling tired
Muscle spasms
double vision
Numbness and tingling
Sexual problems
Poor bladder or bowel control
Pain
Depression
Problems focusing or remembering
What Causes MS?researchers don’t know for sure what causes this disease, but there are many things that to make the disease more likely. People with certain genes may have higher chances to have it. Smoking also may cause the risk.
Some people may get MS after they have had a viral infection with the Epstein Barr virus or the human herpesvirus 6 that makes their immune system not working normally. The infection may trigger the disease. Scientists are studying the link between viruses and MS, but they don’t have a good answer yet.
Some studies suggest that vitamin D, which you can get from sunlight, may strengthen your immune system and protect you from MS. Some people with higher chances of getting the disease who move to sunnier regions seem to lower their risk.
There is no cure way for MS now, but a number of treatments can improve how you feel and keep your body working.
Your doctor can prescribe drugs that may slow the course of the disease, prevent attacks, ease your symptoms, or help you manage the stress that can come with the condition.

Daclizumab
Dalfampridine
