Multiple sclerosis (MS) is one of the most common diseases of the central nervous system. Today more than 2,000,000 people around the world 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.

Symptoms vary widely and include blurred vision, weak limbs, unsteadiness, pain and fatigue. 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.

This film is a joint project of the Multiple Sclerosis International Federation (MSIF) and the Hertie Foundation launched on the first ever World Multiple Sclerosis (MS) Day, 27 May 2009. It aims to capture the attention of people worldwide, motivate them to learn more about MS and become involved in the global MS movement. Show your support today! Register at worldmsday.org
