Abstract: Objective To investigate the long-time electroencephalogram(EEG) characteristics of the patientswith post-stroke depression(PSD).Methods We collected 101 patients with PSD, and gave them the long-time EEG test, thencalculated the time of the δ、θ、α、β wave in the first 10 s after the Open-Closed eyes test and theproportion of the sleep stages S1、S2、S3、S4 and rapid eye movement(REM) in the all sleepingtime. All these data were compared with the healthy control group's EEG structure.Results The slow wave(δ and θ wave) increased significantly in PSD group than that in thecontrol group(δ wave P =0.001, θ wave P =0.005), α wave significantly reduced and β wave hadno significant difference. Compared with the healthy control group, the proportion of the sleepstages S2、S3、S4 of PSD group were reduced(the P followed by 0.008, 0.004). The proportion ofthe stage S1 and REM was increased (the P followed by 0.001 and 0.006).Conclusion The slow wave increased in the PSD patients' EEG. The light sleep increased, and themoderate-deep sleep reduced in the PSD patients.
