Aim. The aim of the study. Study of the state of cognitive functions (CF) and cerebral autoregulation (CA) in patients with cerebrovascular pathology (CVP), which was formed against the background of the consequences of COVID-19. Materials and methods. 108 patients (49 men and 59 women) who suffered from COVID-19 were examined, including those with chronic cerebral ischemia (CCI) in compensated (I group n=24) and subcompensated (II group n=38) stages, and 46 patients (III group) who suffered an ischemic stroke (II) in the post-epidemic period. CF research was conducted using the Mini-Mental State Examination (MMSE) scale, the Frontal Assessment Batter (FAB) test battery, a 10-word memorization test. (KrO2) load, vasomotor reactivity index (IVMR), functional nitroglycerin test (KrFNT). The obtained results were statistically calculated using the parametric ANOVA test and the non-parametric Kruscall-Wallis test. Results. According to the MMSE scale, the average score is in the range of mild cognitive disorders (CD) (25.5±0.6 points – I group), as well as mild dementia (23.6±0.2 and 20.9±0.4 points in groups II and III, respectively), in group III these values border on moderate dementia. In the FAB test, moderate CD with impaired praxis and spatial activity (group I), severe CD with impaired praxis and physical function (group II) and dementia (group III) were noted. A decrease in KrCO2 indicators was observed in patients of all groups, KrO2 values in group I did not change significantly, in groups II and III they were significantly reduced. IVMR values were slightly reduced in group I (62.9±7.5, CG – 71.5±6.9), sharply decreased in groups II and III (group II – 51.2±4.6, p<0 .05; III group – 42.1±3.9, p<0.05). Also, in groups II and III, significantly pronounced hyporeactivity to FNT was noted. Conclusions. Moderate CD of praxis and spatial activity was noted in patients with compensated CCI, severe CD with impaired control over activity and praxis was observed in the subcompensated CCI group, signs of vascular dementia were noted in patients with II consequences. The most significant decrease in IVMR indicators as an integral indicator of the state of CA is observed in patients with II, also a significant decrease of this index is noted in the subcompensated group of CCI, which confirms the high probability of the development of II in this group of patients.
