Abstract
Differences in phase synchronization between intermittent photic stimulation and electrical activity of the brain recorded as electroencephalographic (EEG) patterns were studied in two groups of patients with chronically elevated arterial pressure with and without cognitive impairment. It was found that the parameters of phase synchronization calculated using synchrosqueezed wavelet transform of the light stimulus and the EEG pattern can be used as neurophysiological markers of moderate cognitive impairment.
