However, it is now recognised as the first episode of neurological symptoms that someone may experience, generally lasting for at least 24 hours. CIS can be the first indication that a person has MS.

What causes multiple sclerosis? In MS, the immune system attacks the myelin sheath, which protects and covers the nerve fibres in the brain and spinal cord. The myelin sheath becomes inflamed in small patches which disrupt the messages signals travelling along the nerves, leading to the neurological signs and symptoms of MS. It is not yet understood what causes the immune system to attack the myelin sheath, but some of the factors that may play a role in the development of MS include: Genetics: The chance of developing MS is higher if a link family member for example, a parent or sibling has the disease. Environment: Lack of sunlight and low levels of vitamin D are associated with a greater risk multiple sclerosis hereditary risk MS.
Smoking: People who smoke have a higher risk of developing MS than non-smokers. Weight: People who were obese in their teenage years have an increased risk of developing MS. MS is not directly inherited.]
