Exposure to paint, varnish, and other solvents can put people at a 50% higher risk of developing multiple sclerosis (MS), a study has indicated. Those who have been smokers with solvent exposure and the MS genes are 30 times more likely to develop MS than those who have never smoked or been exposed to solvents and who do not have the genetic risk factors.
The symptoms of MS differ from person to person and over the course of the disease depending on the location of affected nerve fibers. Some include numbness or weakness in one or more limbs; partial or complete loss of vision; double vision; tingling or pain in the body; electric-shock sensations; tremors, lack of coordination; slurred speech; fatigue; dizziness; and problems with bowel and bladder function.
As per a recent research, people with MS who are vitamin D deficient tend to suffer more significant progression of the disease.
