The condition and the treatment

Multiple sclerosis is a disease in which areas of the brain and spinal cord become damaged by the body's own immune system.

There are different types of the condition. One type is relapsing–remitting multiple sclerosis, in which people have flare-ups of symptoms (relapses) followed by a period of recovery (remission). Active relapsing–remitting multiple sclerosis is when there have been 2 clinically significant relapses in the previous 2 years.

Alemtuzumab (also known as Lemtrada) is a drug that is thought to work by modifying the body's immune system to stop it attacking the brain and spinal cord.
