Abstract

Objectives High frequency left-sided (HFL) and low frequency right-sided (LFR) unilateral repetitive transcranial magnetic stimulation (rTMS) are efficacious in treatment-resistant major depression (TRD). Similar benefit has been suggested for sequential bilateral rTMS (LFR then HFL). There are few published reports on the efficacy of sequential bilateral rTMS compared to HFL and sham rTMS. Therefore, this study evaluated the efficacy of HFL and sequential bilateral rTMS compared to sham in TRD. Methods Subjects between the ages of 18 and 85 were recruited from a tertiary care university hospital. Seventy-four subjects with TRD and a 17-item Hamilton Depression Rating Scale (HDRS) greater than 21 were randomized to receive unilateral, bilateral, or sham rTMS. The rates of remission were compared among the three treatment groups. Results The remission rates differed significantly among the three treatment groups using a modified intention to treat analysis that excluded subjects who did not respond to electroconvulsive therapy (ECT) during the current episode. The remission rate was significantly higher in the bilateral group than the sham group. The remission rate in the unilateral group did not differ from either group. Conclusion These findings warrant larger controlled studies that compare the efficacy of sequential bilateral rTMS and HFL rTMS in TRD.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Prior research has indicated that the sequential bilateral approach involving inhibitory stimulation (1 Hz) to the right DLPFC and excitatory stimulation (10 Hz) to the left DLPFC has exhibited efficacy with standard rTMS and cTBS on the right and iTBS on the left, and has recently demonstrated effectiveness in older individuals.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
