Clinically Isolated Syndrome

Clinically Isolated Syndrome (CIS) presents the same symptoms as MS, but patients undergo only one episode (flare-up of symptoms), while those with MS have at least two episodes. 

CIS can develop into MS, but this does not occur in every case. Accurate diagnosis and treatment are essential to ease symptoms and prevent further damage if MS does develop.
