Primary progressive multiple sclerosis – demographic and clinical data from selected voivodeships Review article
Main Article Content
Abstract
Progressive multiple sclerosis, particularly in primary progressive form, is nowadays an object of intensive research and livid discussion. Distinct differences in symptoms, progression, and lesions found in MRI observed in primary progressive form cases lead to speculations that it may in fact be a different demyelinating disease altogether. Primary progressive form is characterized by a gradual increase in spinal cord symptoms with little fluctuation, but without evident relapses. This form of multiple sclerosis is still poorly researched, but it is estimated that primary progressive form cases constitute 10–20% of all multiple sclerosis patients. In the article, based on data from Registry of Multiple Sclerosis Patients, we presented polish observations concerning progression of this form of multiple sclerosis and its differences in comparison to the relapsing- remitting form. We came to the conclusion that the PPMS form is present in around 10% of Polish multiple sclerosis patients, the first symptoms appear around the age of 40 equally often for males and females, and diagnosis of primary progressive form takes more than twice as much time as diagnosis of relapsing-remitting form.
