Relapsing remitting (RR); benign (BB); secondary progressive (SP); and primary progressive (PP) multiple sclerosis patients were selected. A group of 42 sex and age matched healthy controls (HC) were enrolled in the study as well. F: female, M: male. Average and range of age are reported, EDSS: Expanded disability status scale. Age values are not significantly different among MS subgroups; EDSS, as expected, is higher in PP and SP subgroups in comparison with RR and BB.
