MS is the most common disabling neurological condition affecting young adults. Around 85,000 people in the UK have MS.
MS is the result of damage to myelin - a protective sheath surrounding nerve fibres of the central nervous system. When myelin is damaged, this interferes with messages between the brain and other parts of the body.
For some people, MS is characterised by periods of relapse and remission while for others it has a progressive pattern. For everyone, it makes life unpredictable.
The MS Society is the UK's largest charity dedicated to supporting everyone whose life is touched by MS.
