Objective To investigate the effect of high frequency transcranial magnetic stimulation on depression and sleep quality in poststroke depression patients with insomnia. Methods 63 patients with PSD were randomly divided into observation group (n=32)and control group (n=31). Both groups were treated by 10~20 mg escitalopram citalopram for 4 weeks. The patients in observation group also accepted 10 Hz rTMS 10 times (i.e., as a course), while the patients in control group were treated by sham stimulation. At the baseline and 4th week, the 17-item Hamilton depression scale (17-HAMD), Pittsburgh Sleep Quality Index (PSQI)and polysomnography (PSG)were evaluated. Results The sleep parameters, PSQI scores and HAMD scores among two groups had no significant difference at baseline. After 4 weeks treatment, the HAMD score, PSQI score, total sleep duration, sleep efficiency and proportion of rapid eye movement sleep in both groups were improved compared with those before treatment. The descend range of HAMD score in observation group was larger than that in control group (t=2.590,P=0.012), while the descend range of PSQI scores(t=0.897,P=0.373)and the change of the sleep parameters in the two group had no obvious difference. Conclusion High frequency rTMS has better curative effect than antidepressant therapy on depressive symptoms of PSD,while there was no difference on the effect to improve the sleep quality and sleep structure of PSD between these two treatments.
