ROLE NONSPECIFIC REGULATORY SYSTEMS OF BRAINSTEM THE EFFECTIVENESS OF CAROTID ENDARTERECTOMY IN THE ACUTE PERIOD OF ISCHEMIC STROKE
Abstract
Introduction. The neurophysiological methods of studying spontaneous and evoked brain activity have acquired the greatest relevance. They are able to identify functional disorders that
are of great prognostic value. The aim of the study is to study the dynamics of spectral EEG indices and indices of auditory brainstem evoked potentials in patients with ischemic atherothrombotic stroke of varying severity. Materials and methods. We examined 106 ischemic stroke patients of moderate severity, who underwent carotid endarterectomy in the first 2 weeks and 2 weeks after the development of the stroke, analyzed the dynamics of the spectral characteristics of the EEG and the amplitude-latency indices of auditory brainstem evoked potentials in the postoperative period. Research results. We compared the dynamics of power spectra, latency inter-peak intervals and amplitude of auditory brainstem evoked potentials in the postoperative period. Operationin the first two weeks after the development of a stroke leads to a suppression of the spectrum of alpha and beta activity, the absence of significant latency, amplitudes and the value of peak intervals in the dynamics of the postoperative period, which determines a longer recovery of neurological deficit in the postoperative period.
