Abstract
Multiple sclerosis (MS) is chronic demyelinating disease of the central nervous system. It usually affects middle-age adults, causing disability which may render the patients unable to perform everyday-life activities, also with economic consequences. The aim of our study is to present the most important studies evaluating costs of MS in different countries and to compare their results with results obtained in Poland. Additionally we indicate on the problem of using alternative methods by MS patients concluding that this phenomenon should be considered as it might affect the total costs of MS.
