Polysomnography in diagnosis of post-stroke depression
Abstract：AIM:To investigate the value of the polysomnograpy(PSG) in diagnosis of post-stroke depression(PSD).
METHODS:PSG analysis was performed on 3 groups of 30 subjects, with 10 PSD patients diagnosed according to DSM-IV criteria in the experimental group,10 post-stroke patients without depression in the control group,and 10 age and gender matched healthy subjects.
RESULTS:In comparison with healthy and control subjects,there was significant difference in the sleep schedule in PSD patients,represented by prolonged sleep latency,increased number of cycles of REM-NREM,deceased latency of REM stage,more active and frequent REM,and increased S1 stage but decreased S2 and S3+ 4 stages of sleep.In PSD patients,the total sleeping time and slow wave sleeping time were shorter than that in the healthy subjects,but did not differ from that in control subjects.There was no significant difference in duration of wakefulness and sleep efficiency among three groups.
CONCLUSION:Changes in PSG have been shown in PSD patients.These changes may be helpful references for the diagnosis of PSD.
