Abstract
The most susceptible to vascular dementia persons with lesions of small cerebral vessels. This variant of the pathology is characterized by subacute course and pathologic basis is diffuse changes in the white matter of the cerebral hemispheres and lacunar infarctions, in most cases - multiple. That is why the appearance of lacunar infarcts associated with step-progression of the disease. However, not in all cases, there is a significant cognitive defect even in a lacunary condition. The aim of the study was to identify cognitive impairment in patients with lacunar stroke, depending on hemispheric lateralization of the lesion. We observed and surveyed 70 patients (mean age 60.2 + 6.3) suffered the lacunar stroke with hemispheric lateralization of the lesion. In this work, we used the Mini-Mental State Examination (MMSE) and Montreal scale assessment of cognitive functions (MoCA), the Saint Louis University Mental Status Examination (SLUMS), which have been developed as a tool to identify and assess the severity of cognitive functions in general practice. Comparative analysis of cognitive impairment on the stage of the disease in the control group showed that in general, patients suffered lacunar stroke level of violations was significantly higher than the control group (p≤0.01). Cognitive function in right lacunar stroke corresponded moderate cognitive impairment and the restoration of the neurological defect in the dynamics were less expressed and are not complete. Cognitive impairment in the left hemisphere lacunar stroke had a mild degree of cognitive impairment and restoration of disturbed functions is progressing at a faster pace, about what speak reliable indicators of the late recovery period (p≤0.05). The differences in cognitive disorders at different focus lateralization underlie the clinical features and determine the nature and pace of the recovery of lost functions. Mild cognitive impairment in the left-hand lacunar stroke is a favorable prognostic factor in terms of the recovery of lost functions.
