CASALLAS VANEGAS, Adriana; ZULUAGA RODAS, Maria Isabel  and  REYES GUERRERO, Marco Aurelio. Clinically isolated syndrome: approach to the first demyelinating event. Acta Neurol Colomb. [online]. 2019, vol.35, n.2, pp.64-73. ISSN 0120-8748.

Clinically Isolated Syndrome (CIS), denotes the first neurological symptom suggestive of Multiple Sclerosis (MS), at least 24 hours in duration; In the absence of fever, infectious processes and encephalopathy. It is characterized by its frequent presentation in young adults and affects the optic nerve, brainstem or spinal cord. The early stratification of CIS is essential because with clinical, radiological and biological predictors, the risk of conversion to MS can be established. The use of Disease Modifying Therapies (DMT) in CIS has been shown to delay the conversion of CIS to Multiple Sclerosis by 44 to 50 %%. However, not all patients with CIS will evolve to MS, so the study of several prognostic markers will allow to recognize the ideal scenario where patients benefit from the early onset of DMT.
