Multiple sclerosis (MS) is an autoimmune disease. The cause is still unknown. The body’s immune system attacks its own tissues, destroying myelin (a substance that protects nerves in the brain and spinal cord).Emotional stress is a big part of having a chronic disease like multiple sclerosis. Stress leads to common MS symptoms such as fatigue, depression, and confusion.
When a person has multiple sclerosis, their immune system attacks the central nervous system, affecting the brain, spinal cord, and optic nerves. Symptoms can vary, they come and go, making the disease hard to diagnose. The effects are often different for everyone who has the disease.
Some people get the disease after they’ve had a viral infection, when the virus makes the immune system stop working normally. Scientists still can’t grasp the connection between MS and viruses. Some researchers found that areas with more sunlight seem to lower risks for multiple sclerosis.
