World Multiple Sclerosis Day (AKA World MS Day) is a day to raise awareness, and campaign for and with everyone affected by MS all over the world. MS is a disease in which the immune system attacks the protective covering of the nerves which disrupts the communication between the brain and the rest of the body of those affected. This disease is potentially disabling. As of today, there is still no cure for this disease though, treatment may ease the symptoms.

World Multiple Sclerosis Day is observed every year on May 30th.

The first Multiple Sclerosis day was initiated in 2009 by MS International Federation in order to raise awareness for this disease and hopefully raise enough funds to be able to find a cure.
