Key result
Nonlinear photostimuli-EEG phase analysis can identify markers of cardiovascular disease and cognitive impairment.
Why the study?
Does the application of nonlinear dynamics methods to EEG patterns identify markers of cognitive impairment in patients with hypertension and atrial fibrillation?
Does the application of nonlinear dynamics methods to EEG patterns identify markers of cognitive impairment in patients with hypertension and atrial fibrillation?
Nonlinear dynamics methods analyzing EEG responses to photostimulation may serve as markers for cognitive impairment in patients with hypertension and atrial fibrillation.
Nonlinear dynamics may identify markers of cognitive impairment in hypertension and AF; leaves open prospective validation before clinical use.
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.

O. E. Dick (2023) conducted a review in Chronically elevated blood pressure and atrial fibrillation with or without moderate cognitive impairment. Nonlinear dynamics methods (phase synchronization) was evaluated on Identification of markers of disorders. Nonlinear dynamics methods analyzing phase synchronization between rhythmic photostimuli and EEG patterns can identify markers of cardiovascular disorders and moderate cognitive impairment.
