The objective of the present study was to investigate the linguistic profile of patients with multiple sclerosis and to establish a connection between the corresponding linguistic deficits and specific brain regions. Specifically, for the purposes of this research, 12 adults diagnosed with secondary progressive multiple sclerosis were examined and compared with healthy participants. The Boston Aphasia Naming Test, a standardized linguistic tool, was administered, focusing on the subtests for auditory comprehension, repetition, and reading comprehension. The results demonstrated that the group of participants with multiple sclerosis exhibited significantly lower performance in the comprehension subtest compared to the control group. The findings are discussed.
