Quantitative electroencephalogrpaphic indexes in patients with ischemic stroke
To study the central nervous system condition in patients with ischaemic stroke data of neurophusiological invesigations were estimated by quantitative electroencephalogrpaphic method and by the using of polispectral indexes as informative parameters and indexes cerebral conditions after patients hospitalization. The effectivity of the treatment estimated by using of the scale of National institutes of health - National institute of neurological disorders and stroke, parameters of which with correlation-regression analysis compared with the polispectral indexes of quantitative electroencephalogrpaphic and it was obtained respective correlations. Increasing of the indexes levels of the ratio teta-rhytm to the alpha-rhytm, teta- rhytm to the beta- rhytm, alpha-rhytm to the beta- rhytm were obtained in patients in comparing with control group. It may be recommended that method of quantitative electroencephalogrpaphic may be use as additional diagnostical approach of stroke damaging of brain functions That is confirmed by results of linear regression analysis in which course the correlation relationships speaking about a close connection of specified parametres with severity level of a condition of patients are received. In the same time spectral indexes of quantitative electroencephalogrpaphic can be use as informative parameters, which are the quantitative indexes of cerebral condition during treatment, as they changed under the influence of spent therapy.
