Multiple Sclerosis (MS) is a chronic disease that affects each person differently, with symptoms ranging from forgetfulness and numbness in the limbs, to loss of vision and paralysis. MS occurs when the body’s immune system attacks the central nervous system, damaging the protective layer covering the nerves (called the myelin sheath). These nerves carry signals between the brain and spinal cord and the rest of the body. When the protective layer (myelin sheath) is damaged, the signals transmitted by the brain are disrupted. Depending on where the damage occurs in the CNS and to which nerves, determines what symptoms are experience by an affected person. 


The body does have an ability to repair some of the damage caused by the immune system, hence why symptoms can sometimes reduce or resolve. However, it is now understood that there may also be some damage occurring, without causing noticeable symptoms. This is known as “smouldering MS”. Learning about brain health, and how to maintain it, is important for everyone, but even more so for patients with MS. Sanofi is committed to maintaining long-term partnerships with patients, physicians, advocates, and researchers to make a significant impact on people living with MS.
