What is MS?

http://static.howstuffworks.com/gif/multiple-sclerosis-demyelinization.gifMultiple Sclerosis (MS) is a disease of the central nervous system which damages the protective coating (Myelin sheath) around the nerves which transmit messages to all parts of the body, especially connected with the control of muscular and sensory activity
When myelin is damaged, scar-like tissue forms. This hardened tissue makes it difficult for the nerves to send signals and messages to & from organs, muscles and the skin.

Types of MS

Benign MS
Usually dormant or inactive for fifteen or more years. No expression of symptoms or any serious enduring disability.

Relapsing/Remitting
MS ChartRelapses followed by periods of remission.
Relapse - New symptoms can appear and old ones resurface or worsen. Relapses can last for days, weeks or months.
Remission - Symptoms reduces, recovery from relapses can be fully or partially and it can usually be slow and gradual.

Secondary Progressive MS:

Secondary progressive MS, as the name suggests, sees a progressive increase in people’s symptoms between relapse and remission, but this progression can be very slow. Changes might be so slight that they are hard to notice until much later.

Primary Progressive MS:
This type of MS is characterised by a gradual progression of the disease from its onset with no remissions at all.
