Multiple sclerosis (MS) is an inflammatory disease in its early stages whose primary or secondary immunological mechanisms produce reversible or irreversible lesions in the myelin and axons in the central nervous system.

The first case of MS in Cuba was reported in 1965.

Current prevalence of MS is considered to be 10 cases/100 000 inhabitants.


The aim of this study was to characterise MS in Western Cuba from a clinical point of view and in comparison with other similar studies carried out in two other regions in the country.


50 patients living in the western region were clinically assessed.

Statistical tests were carried out to compare this survey with two similar studies conducted in the central and eastern regions.


By far the majority of results compared with the series from the central region and from Santiago de Cuba were similar, but some significant differences did appear on comparing these two series.


The study shows the characteristics of the disease in the Western region valuated using distinct parameters and several differences between the three series can be observed fundamentally with regard to skin colour, triggering events, symptoms at onset and functional involvement in the forms of progression.
