ABSTRACT
BACKGROUND:
Generalized anxiety disorder (GAD) is a common chronic mental disorder, and it also can cause depressive symptoms and cognitive impairment. The primary aim of this study was to determine whether inflow-frequency transcranial magnetic stimulation (ILF-TMS) improves anxiety symptoms in patients with GAD.METHODS:
Sixty-two patients with GAD were randomly divided into 2 groups. Thirty-one patients in the active ILF-TMS group and 31 patients in the sham ILF-TMS group. All participants were assessed at baseline, week 2, week 4 and week 12. The intention-to-treat methodology was used for the analysis.RESULTS:
The response rate was higher in the active group than in the sham group, with a significant difference at week 12 (response rate 80.6% vs. 54.8%, respectively; Pâ¯=â¯0.03). Although the remission rate was higher in the active group at week 12, there was no statistically significant difference between the groups (remission rate 71.0% vs. 48.4%; Pâ¯>â¯0.05). No statistically significant differences on the Hamilton Depression Rating Scale, Clinical Global Impression scale, and neurocognitive test between groups were observed (overall Pâ¯>â¯0.05). Adverse events that occurred in the active group were similar to those in the sham group, with no significant differences (Pâ¯>â¯0.05).CONCLUSION:
The response rate was higher in the active group at the end of the trial, which indicated that ILF-TMS may be an effective and safe adjunctive tool to improve anxiety symptoms in patients with GAD.
