Multiple sclerosis is an inflammatory and degenerative disease of the central nervous system which affects young adults. The prevalence of multiple sclerosis in the world is heterogeneous and is low in Ecuador. The diagnosis is based on the McDonald 2017 criteria. Once the diagnosis has been made, it is necessary that any negative factors which will impact the type of treatment used be identified. At this time, factors such as epidemiological, clinical, biomolecular, and magnetic resonance images, which will allow us to identify if the case is aggressive or benign, are studied. The number of lesions shown in a brain MRI, the presence of lesions in the brain stem and spinal cord are factors which have been demonstrated to have an impact on the progression of disability. The presence of oligoclonal bands in the cerebrospinal fluid has a fundamental role in the conversion of an isolated clinical syndrome to multiple sclerosis. Low levels of vitamin D have been associated with a negative prognosis, however how important vitamin D is in the prognosis of MS in countries such as Ecuador is still an area to be studied.

Palabras clave : Multiple Sclerosis clinically defined; clinical isolated síndrome; neurofilaments; oligoclonal bands.
