What is Multiple Sclerosis?
Multiple sclerosis is a disease which attacks the myelin sheath – the fatty coating of nerve cells which is essential to the functioning of the central nervous system. Disruption to the myelin sheath interferes with the transmission of signals between the brain, the spinal cord and the peripheral nerves. In the places where the myelin is damaged scares called lesions or plaques occur.
Multiple Sclerosis is most commonly diagnosed in people in their 20s and 30s, although it can develop at any age.
