Daytime qEEG Hyperarousal Model in Psychophysiological Insomnia
To address a hyperarousal model with daytime qEEG frequency bands fluctuations in frontal, central, and parietal regions in Psychophysiological insomnia(PPI) compared to good sleepers(GS).
qEEGs in resting states of Patients with Psychophysiological insomnia (n = 16) were contrasted with those with good sleep (n = 20). To serve this purpose, the daytime hyperarousal model is developed with a linear model.
psychophysiological insomnia(PPI) recorded significantly high beta band activity in all brain regions as their eyes closed condition compare to the control. In addition, low frequency in the frontal region and high frequency in the parietal and central regions were detected in eyes open conditions.
The hyperarousal model results suggest that patients with psychophysiological insomnia were undergoing daytime neurophysiological hyperarousal because of upregulation in arousal and low-frequency band fluctuation in the frontal region in eyes closed condition is the most effective index.
