Abstract
BACKGROUND: Multiple sclerosis is the one of leading causes of non-traumatic disability in young adult patients. An in-depth understanding of the processes of neuroplasticity underlying rehabilitation measures will ensure full and effective recovery of patients with this disease.
AIM: To evaluate changes in the brain connectome in patients with multiple sclerosis in response to complex rehabilitation.
MATERIALS AND METHODS: A prospective cohort study included 20 patients with relapsing-remitting multiple sclerosis (EDSS 1.5–6.5) in remission. All patients underwent comprehensive inpatient neurorehabilitation in a volume corresponding to individual rehabilitation needs for 5 weeks. To assess changes in the connectome, resting-state functional magnetic resonance imaging (rs-fMRI) was performed at three points: before the start of rehabilitation, immediately after its completion, and one month after discharge from the hospital. Statistical analysis is carried out using the CONN 7 (based on MathLab). Clinical neurological examination included examination using functional tests, passing questionnaires, and determining scores on the EDSS scale before and after rehabilitation.
RESULTS: A total of 20 patients were examined, 13 of them at three control points. According to rs-fMRI data, clusters of decreased connectivity were identified between the left parahippocampal gyrus and the lateral cortex of the right occipital lobe, and between the right parahippocampal gyrus and the precuneus (p-FWE, p-FDR of cluster size and mass <0.05). Clusters of increased connectivity were determined between the left inferior temporal gyrus and the lateral occipital cortex of the left hemisphere, between the left middle temporal gyrus and the right frontal field, between the pole of the left temporal lobe and the lateral cortex of the left hemisphere (p-FWE, p-FDR of cluster size and mass <0.05). Other clusters of sufficient size demonstrated borderline statistical significance (individual adjusted p values for cluster size and mass exceeded 0.05).
CONCLUSION: The identified changes indicate a functional reorganization of brain structures responsible for the perception of complex visual information, the functioning of executive control systems, as well as the implementation of memory and sequential action planning.
