What is CIS?
CIS is an episode of inflammation of the brain or spinal cord, for example:
- a temporary problem with eyes (for example: pain, double or blurred vision) and because of this a person may be referred to a specialist eye doctor.
- a problem with muscle strength, balance or coordination (which may have affect walking), or a sensory problem such as pain, numbness or tingling in limbs.
The problem may have lasted for a few days or for several weeks.
Some people who have an episode of inflammation may eventually go on to develop multiple sclerosis (MS). Although they do not have a diagnosis of MS, we invite them to take part in SWIMS as we wish to identify all patients who have had episodes of inflammation, whether a single event or as part of a more progressive course.
