What is Multiple sclerosis (MS)?

Multiple sclerosis (MS) is a condition affecting the brain and spinal cord, in which the immune system mistakenly attacks the protective covering (myelin) around nerve fibres. This disrupts the flow of information between the brain and the rest of the body.

Symptoms vary widely between individuals and can include fatigue, vision problems, numbness or tingling, muscle weakness or spasms, balance difficulties, and problems with thinking or memory. Many people experience a relapsing-remitting pattern, with symptoms flaring up and then easing over time.
