Characteristic features of hemispheric coherence in EEG patients diagnosed with ischemic stroke

Coherent EEG characteristics in 63 patients with ischemic stroke in the acute period were analyzed. Dynamics of intrahemispheric EEG coherence and clinical parameters in patients with varying severity of the condition were compared. It is shown that characteristics of changes in the values of the affected intrahemispheric coherence and clinically intact hemisphere in the acute phase have clear relationships with the severity of ischemic stroke. It also has an important prognostic value of the disease. In patients diagnosed with severe ischemic stroke, low rates of intrahemispheric coherence in the frontal-temporal and frontal-central areas of clinically intact hemisphere were observed.
