The protective coating around nerve fibres in the central nervous system is damaged in people with MS Getty

Around 2.5 million people around the world live with multiple sclerosis, an unpredictable condition affecting the central nervous system. Among many other symptoms, blurred vision, loss of balance, slurred speech, tremors, blindness and memory problems are characteristic of MS, but the problems can come and go and may worsen over time.

More than 100,000 people in the UK have been diagnosed with the neurological condition, with almost three times as many women as men affected. On World MS Day, marked on 27 May, IBTimes UK looks at facts and figures about MS.
