N2 - Objective. To identify clear patterns of the cerebral cortex atrophy in multiple sclerosis that may provide valuable information for the development of additional paraclinical methods of stages and variants of MS objectification and verification and used for assessing treatment efficacy. Material and methods. The results of morphometric data analysis of 117 patients with different variants of MS and 25 healthy volunteers are presented. The original algorithm for postprocessing MRI images was used. Age, disease duration, type of disease, FS and EDSS scores, morphometric results were the source parameters for the statistical analysis. Results. The correlation analysis showed that the total cortex volume was in inverse correlation with EDSS score, pyramidal and cerebellar dysfunction, but not with disease duration. An analysis of regional changes in 43 bilateral regions of interest (ROI) demonstrated similar results in 7 ROIs in the left (dominant) hemisphere and in 4 ROIs in the right hemisphere. ANOVA revealed atrophic changes in 20 ROIs bilaterally. Deficit of certain functional systems was accompanied by the atrophy of various functional cortex regions. ANOVA of the regional cortical atrophy in groups with varying disease severity showed the presence of significant changes in patients with moderate to severe disability. Duration and type of MS were not predictive for development of atrophy, with the exception of the precuneus bilaterally, the right paracentral lobule and right posterior cingulate gyrus. Conclusion. Regional cortical atrophy is detected in the earliest stages of the disease and increases as the disease progresses. Inconsistency of data across studies can be explained by the lack of generally accepted morphometric standards and pathogenetic heterogeneity of MS. Regional cortical atrophy may be considered as a sensitive neuroradiological biomarker for MS.
