Neuronavigated rTMS for Treatment-Resistant Auditory Hallucinations (fuNEEG)

2026年9月23日 更新者:Psychiatric University Hospital, Zurich

Functional Neuronavigated EEG and TMS-treatment of Chronic Acoustic Hallucinations

Auditory verbal hallucinations (AVH), such as hearing voices in the absence of an external sound source, are a common and distressing symptom of schizophrenia. In some patients, hallucinations persist despite treatment with antipsychotic medication. Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain stimulation technique that may reduce auditory hallucinations by decreasing activity in brain regions involved in auditory and language processing.

This randomized, double-blind, sham-controlled study will investigate whether individualized, neuronavigated inhibitory rTMS can reduce persistent auditory verbal hallucinations. Forty adults with medication-resistant auditory hallucinations will be randomly assigned to receive either active rTMS or sham stimulation.

For each participant, the stimulation target in the primary auditory cortex will be individually identified using electroencephalography (EEG), acoustic evoked potentials, and magnetic resonance imaging (MRI)-based neuronavigation. Participants will receive two rTMS sessions per day for five consecutive days. The severity of auditory hallucinations will be assessed before and after treatment and at a 28-day follow-up.

The study will also investigate whether treatment is associated with changes in brain activity and functional connectivity measured by EEG, including changes in the P300 event-related potential.

介入・治療
実験的:Active rTMS

Participants receive individualized, neuronavigated inhibitory rTMS targeting the primary auditory cortex. The stimulation target is individually determined using EEG-based auditory evoked potentials and MRI-based neuronavigation. Treatment is administered twice daily for five consecutive days.

Individualized neuronavigated inhibitory rTMS is applied to the primary auditory cortex. The individual stimulation target is determined using EEG-based auditory evoked potentials and MRI-based neuronavigation. Stimulation is delivered at 1 Hz on five consecutive days, with a total of 12,000 magnetic pulses administered over the treatment course.

偽コンパレータ:Sham rTMS

Participants undergo the same treatment schedule and neuronavigation procedures as the active rTMS group using a sham coil that is visually and acoustically similar to the active coil but does not deliver active magnetic stimulation.

Sham stimulation is administered using the same neuronavigation procedures and treatment schedule as active rTMS. A sham coil visually and acoustically resembling the active coil is used but does not deliver active magnetic stimulation.
