Because MS affects individuals so differently, it is difficult to make generalizations about disability. Statistics suggest that two out of three people with MS remain able to walk over their lifetimes, but many of them will need a cane or other assistive device. Some choose to use a scooter or wheelchair to conserve energy. Multiple sclerosis is not fatal. Most people with MS learn to cope with the disease and live full, productive lives.
Women develop the disease at a rate almost double that of men.
MS occurs most commonly among Caucasians, especially those of Northern European ancestry, but people of African, Asian, and Hispanic backgrounds are not immune. The disease is most frequently found among people in colder climates. Studies also indicate that genetic factors make certain individuals more susceptible to the disease, but there is no evidence that MS is directly inherited. Multiple sclerosis is not contagious. MS is not always easy to detect or diagnose.
