Summary

First clinical studies indicate an effect of repetitive transcranial magnetic stimulation(rTMS) in the treatment of auditory hallucinations (AH). However, effect size, optimal stimulation site and parameters are unclear. With this randomized, placebo-controlled clinical trial we test the efficacy and safety of bilateral continuous theta burst stimulation (cTBS), a patterned form rTMS, against auditory hallucinations. The treatment will be applied add-on to individual antipsychotic and behavioral therapy. Patients will be treated for 6 weeks each weekday (30 sessions) with 40s of cTBS (halfway between T3/P3 and T4/P4). For weeks 1-3, half of the subjects will be randomized to a sham-stimulation (coil tilted 45°). During weeks 4-6, all subjects receive real cTBS.

Conditions

  • Auditory Hallucinations

Interventions

PROCEDURE

continuous theta burst stimulation (cTBS)

bilateral continuous theta burst stimulation (bursts of 3 stimuli, 50Hz every 200ms for 40s, 80% active motor threshold) to the temporoparietal cortex (EEG 10/20: halfway T3/P3 and T4/P4)

PROCEDURE

sham cTBS

bilateral continuous theta burst stimulation (bursts of 3 stimuli, 50Hz every 200ms for 40s, 80% active motor threshold) to the temporoparietal cortex (EEG 10/20: halfway T3/P3 and T4/P4) with the stimulation coil tilted 45°
