Abstract

Background Auditory hallucinations are often resistant to treatment and can produce significant distress and behavioral difficulties. A preliminary report based on 24 patients with schizophrenia or schizoaffective disorder indicated greater improvement in auditory hallucinations following 1-hertz left temporoparietal repetitive transcranial magnetic stimulation (rTMS) compared to sham stimulation. Data from the full 50-subject sample incorporating 26 new patients are now presented to more comprehensively assess safety/tolerability, efficacy and moderators of this intervention.Methods Right-handed patients experiencing auditory hallucinations at least 5 times per day were randomly allocated to receive either rTMS or sham stimulation. A total of 132 minutes of rTMS was administered over 9 days at 90% motor threshold using a double-masked, sham-controlled, parallel design.Results Hallucination Change Score was more improved for rTMS relative to sham stimulation (p = .008) as was the Clinical Global Impressions Scale (p = .0004). Hallucination frequency was significantly decreased during rTMS relative to sham stimulation (p = .0014) and was a moderator of rTMS effects (p = .008). There was no evidence of neurocognitive impairment associated with rTMS.Conclusions Left temporoparietal 1-hertz rTMS warrants further study as an intervention for auditory hallucinations. Data suggest that this intervention selectively alters neurobiological factors determining frequency of these hallucinations.

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.
