Multimodal MRI-guided rTMS to Treat Refractory Hallucinations

Not Applicable

Completed

• Conditions: Hallucinations; Perceptual Disorders; Schizophrenia
• Interventions: Device: MagPro X100 repetitive Transcranial Magnetic Stimulation

• Registration Number: NCT01373866
• Lead Sponsor: University Hospital, Lille

Brief Summary

* The efficacy of neuro-navigated rTMS for patients with schizophrenia suffering from drug-resistant multisensory hallucinations will be tested by the implementation of a double-blind randomized controlled trial (RCT)

* This study will use a combination of different MRI modalities (fMRI and DTI) to define with precision rTMS brain-targets in the case of multisensory hallucinations

* The investigators anticipate that multimodal MRI-guided rTMS will allow a significant improvement in the efficacy of neuromodulation treatment of refractory hallucinations
