Based on the results of our original study, we came to the
conclusion that such readily available and objective method as
electroencephalography for the examination of the patients with ischemic
stroke may be useful for the analysis of the parameters of the alpha
rhythm with a view to predicting the development of cognitive disorders
(CD) which is important for the timely prescription of medicamental
therapy and correction of the approaches to the rehabilitative treatment
of these patients. Material and methods. the present study involved 26
patients with ischemic stroke receiving there habilitative treatment and
35 healthy volunteers comprising the control group. All participant of
the study underwent the neurological examination and neuropsychological
testing; the stroke patients were additionally examined with the use of
electroencephalography. Results. It was shown that the increase of the
alpha rhythm amplitude in the anterocentral brain regions to more than
60 mV and its reduction to below 20 mV reflected the disturbed
hierarchical regulation of the functioning of cerebral structures in the
form of the dominant synchronized state of the brain. Its most
pronounced clinical manifestations were cognitive disorders. The
disturbances to the physiological gradient and the alteration of the
alpha rhythm amplitude (to below 20 mV and above 60 mV) in the
anterocentral brain regions accounted for the higher than 70%
probability of detecting moderate CD in the patients with ischemic
stroke. The amplitude of alpha rhythm in the anterocentral brain regions
may serve as an indicator of the effectiveness of the consolidation of
information in the process of memorization and of the speed of
information retrieval; moreover, it is an objective characteristic of
the patients' emotional state. It is concluded that the estimation of
the amplitude of alpha rhythm in the anterocentral brain regions is
needed to predict the course of CD in the patients presenting with
ischemic stroke including those receiving the rehabilitative treatment.
Conclusion. The detailed analysis of the electroencephalograms of the
patients makes possible the well-timed correction of the individual
rehabilitation program and the enhancement of the effectiveness of
recovery of both cognitive and motor functions.
