The investigators aim to examine the safety and efficacy of repeated transcranial magnetic stimulation (rTMS) for the treatment of auditory verbal hallucinations (AVH) in patients with schizophrenia who are not taking antipsychotic medication. The investigators employ a novel, accelerated protocol with only four sessions of low-frequency rTMS in one day. The effects of this accelerated protocol will be compared to the sham stimulation. Additionally, the investigators will examine the effects of rTMS on a neurophysiological level by evaluating mechanism of action in the temporo-parietal lobe by means of functional magnetic resonance imaging.', 'detailedDescription': 'Auditory verbal hallucinations affect up to 70% of schizophrenia patients (Waters, 2012), yet, even extended antipsychotic medication does not ameliorate AVH in 20-30% of patients (Sukhwinder S Shergill et al., 2007) and is often accompanied by side effects (Leucht et al., 2009). Therefore, it is crucial to develop and assess promising potentially beneficial therapeutic options.\n\nNon-invasive brain stimulation techniques like repetitive transcranial magnetic stimulation (rTMS) have been proposed to disrupt mechanisms in question. A number of meta-analyses (Aleman, Sommer, \\& Kahn, 2007; Demeulemeester et al., 2012; Freitas, Fregni, \\& Pascual-Leone, 2009; C. W. Slotema, Blom, van Lutterveld, Hoek, \\& Sommer, 2014; C. W. Slotema, Dirk Blom, Hoek, \\& Sommer, 2010; Tranulis, Sepehry, Galinowski, \\& Stip, 2008) found significant effect sizes ranging from 0.42 to 1.04 for 1Hz rTMS over the left temporo-parietal junction for the treatment of AVH. However, the majority of studies so far investigated the effects of rTMS in treatment resistant schizophrenia patients as an ad-on or second-line treatment.\n\nNo study to date has explored the effects of rTMS either as a first-line treatment or in the initial stage of the illness. This is surprising, considering the fact that rTMS is a safe treatment with minimal side-effects (Rossi, Hallett, Rossini, \\& Pascual-Leone, 2009) that could be used already in the earlier phase of treatment. This stands in considerable contrast to the range of side-effects associated with antipsychotics (Leucht et al., 2017) that can be disabling for patients and lead to lower quality of life.\n\nTherefore, the crucial next step is (1) to explore the effects of rTMS in medication-free patients from the whole schizophrenia spectrum and (2) to use an accelerated protocol of multiple rTMS-sessions within a short period of time. To make this assessment feasible, considering that patients have to be off medication, the safest and also most efficient way is an accelerated rTMS protocol. The great advantage of such an approach is that the effects of rTMS can be investigated independently of potentially influencing effects of antipsychotics and at the same time assess the efficacy of rTMS within a very short amount of time.\n\nIn the proposed study, the investigators aim to determine the efficacy of rTMS as a potential treatment for AVH in schizophrenia and thus reduce suffering in patients and their relatives.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
