Sažetak

Cognitive impairment is one of the most frequently reported symptoms in persons
with multiple sclerosis (MS). The Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS)
has been recommended as a standardized international screening and monitoring tool for brief
cognitive assessment. The aim of our study was to assess the reliability and validity of the Serbian version of
the BICAMS. A total of 500 relapsing-remitting MS (RRMS) patients and 69 age-, gender- and education-
matched healthy control (HC) subjects were examined. All participants performed the BICAMS test
battery, which includes the oral version of the Symbol Digit Modalities Test (SDMT), California Verbal
Learning Test second edition (CVLT-II), and Brief Visuospatial Memory Test Revised (BVMTR). A randomly
selected subset of patients were retested one to three weeks after baseline. Statistically significant differences
between patients and HCs were evident on the SDMT and BVMTR (p<0.001). HCs had higher
CVLT-II scores but this difference did not reach statistical significance (p=0.063). Cognitive impairment,
defined as an abnormal test score on ≥1 subtest, was found in 62.9% of MS patients. There were statistically
significant correlations between BICAMS scores and age, education, EDSS and disease duration in patient
sample. Test-retest reliability was confirmed with Pearson correlation coefficient of 0.70 in all measures.
This study supported the reliability and validity of the Serbian BICAMS, although the CVLT-II version
tested here lacked sensitivity to detect MS compared to healthy volunteers.
