Abstract:
Background:This study aimed to evaluate the therapeutic effect of repetitive transcranial magnetic stimulation (rTMS) as a nonpharmacologic treatment in depressed hemodialysis patients.
Methods:Patients who scored ≥ 5 on the Patient Health Questionnaire-9 were randomized to either the rTMS (n = 7) or sham group (n = 7). The rTMS group was stimulated with a 110% motor threshold and 10 Hz on the left dorsolateral prefrontal cortex for 20 minutes, three times a week, for 4 weeks. In the sham group, the “1-wing 90-degree method” was used. We analyzed clinical indices before and after the intervention, as well as data from quantitative electroencephalography (frontal alpha asymmetry [FAA]), and various psychiatric questionnaires (Beck Depression Inventory-II, Beck Anxiety Inventory [BAI], Symptom Checklist-90-Revised Somatization Subscale [SCL-90R-SOM]), and Perceived Stress Scale.
Results:One month after rTMS, the changes in hemoglobin A1c levels in the rTMS group were significantly greater than those in the sham group (F = 6.687, P = 0.032). The changes in BAI scores in the rTMS group were significantly greater than those in the sham group (F = 6.700,P = 0.025), and the changes in SCL-90R-SOM scores in the rTMS group were greater than those in the sham group (F = 4.943, P = 0.048). In addition, the changes in the FAA value at the F7 and F8 electrodes in the rTMS group were greater than those in the sham group (F = 6.468, P = 0.027).
Conclusion:In depressed hemodialysis patients, rTMS may improve anxiety and somatization symptoms, which may lead to improvements in clinical measures.
