Correlation Between the Revised Brain Symmetry Index, an EEG Feature Index, and Short-term Prognosis in Acute Ischemic Stroke

Abstract

The early prediction of functional outcomes after stroke may enhance clinical management and minimize short-term mortality.

Using Phase Synchrony Index for Improved Assessment of Consciousness in Ischemic Stroke Patients

“…Nevertheless, the comparisons of BSIs in the groups with different lesion sites and lesion side by an analysis of variance both showed no significant difference, and the same result can be found in a study in regard to BSI [24].…”

Predicion of the functional outcome of cerebral ischemic supratentorial stroke acute period on the basis of spectral analysis of the brain bioelectrical activity

“…In accordance with the data of X. Xin et al (2017) poor functional outcomes were associated with higher BSI [18]. Our research studied the prognostic value of interhemispheric different frequency bands asymmetry indexes, while independent association with the functional outcome of CISS acute period was only determined for IHRA of alpha band.…”

Diagnostic value of the integral assessment of electroencephalographic pattern in patients in the acute period of spontaneous supratentorial intracerebral hemorrhage

“…In the study of M. E. Wolf et al (2017), it was found that generalized (bilateral) changes of the bioelectric activity of the brain reflect the severity of supratentorial structures damage in patients with cerebral ischemic hemispheric stroke, not the focal ones [19]. The numerous studies demonstrate a high diagnostic informative value of the integral EEG pattern coefficients, which reflect the severity of slowwave activity within the assessment of the severity of acute brain damage of ischemic and traumatic genesis [2,4,5,17]. The conducted study allowed us to obtain data on reciprocal changes in the anterior and posterior gradient of EEG pattern rhythms in patients with SSICH.…”

“…Moreover, the overwhelming majority of scientific research related to the study of the functional state of cerebral structures within brain injuries of various origins with the use of spectral analysis of bioelectric activity of the brain was aimed at the determination of isolated parameters that are associated with clinical and neuroimaging data and the outcome of the disease [4,7,10,17]. Besides, it is necessary to mention that this monoparametric approach has restrictions, since the functional state of the brain in patients with brain damage in supratentorial localization is a very complex and extremely variable set of relied changes of absolute power, structure, zonal distribution of rhythms of different ranges in affected and intact hemispheres, as well as interhemispheric rhythm asymmetry [2].…”
