Использование количественной электроэнцефалограмы при анализе эффективности лечения ишемического инсульта

Purpose: To study the central nervous system condition of patients with ischaemic stroke (IS) were estimated with quantitative EEG (QEEG) and with the using of polispectral indexes (PSI) which characterize redistribution spectral power between alfa-, beta- and teta-frequency ranges of EEG. Materials and Methods: The effectivity of the treatment estimated by using of the scale NIH-NINDS, parameters of which with correlation-regression analysis compared with the PSI and it was obtained respective correlations. Results: Decreasing of the indexes levels of the ratio teta-rhytm to the alpha-rhytm before/after treatment, teta-rhytm to the beta-rhytm before/after treatment, alpha-rhytm to the beta-rhytm before/after treatment were obtained. Summary: The given methodological approach has allowed to use spectral indexes EEG as informative parameters and markers of cerebral patients conditions. The analysis of spectral power of rhythms EEG in patients with IS has allowed to establish possibility of use of spectral indexes EEG as informative parameters and markers of cerebral conditions in the course of treatment which is carried out.
