Analysis of the Relationship of Moderate Cognitive Impairments with Changes in Synchronization between Photostimulation and Brain Activity

Abstract

Abstract—The review is devoted to the application of methods of nonlinear dynamics to the analysis of dynamic changes in the patterns of physiological rhythms of the brain in the event of disorders associated with chronically elevated blood pressure and atrial fibrillation-type cardiac arrhythmias in the presence and absence of moderate cognitive impairment. The possibility of using these methods to identify markers of these disorders is shown. These markers are associated with the parameters of phase synchronization between rhythmic photostimuli and brain responses in the form of electroencephalographic patterns.
