Özet

Cognitive impairment is common in multiple sclerosis (MS), and visual memory impairments are increasingly considered clinically important, yet still underappreciated.To compare cognitive performance assessed by the Rey Complex Figure Test (RCFT) and Symbol Digit Modalities Test (SDMT) in MS patients and healthy controls, and to examine correlations between these measures and physical disability indices.A total of 177 participants were assessed using RCFT subtests and SDMT, of whom 95 had relapsing-remitting MS (RRMS) and 82 were healthy controls. Group comparisons and correlation analyses were performed.The MS patients scored significantly lower on all RCFT subtests and SDMT. Moderate correlations were found between SDMT and RCFT 0 to 2, but not RCFT 3.Both RCFT and SDMT may serve as potentially complementary measures of cognitive domains relevant to MS. Incorporating both recall and recognition-based measures, along with processing speed assessments, can provide a broader evaluation of cognitive strengths and weaknesses in MS, helping clinicians better characterize patients' profiles.
