NCT02175251

Brief Summary

Auditory Hallucinations (AH) are experienced by 50 to 70% of subjects with schizophrenia. Almost a quarter of patients are medication resistant to such symptoms. The application of rTMS at low frequency in the left temporoparietal cortex reduces AH. A pilot study reported successful treatment of AH with high frequency rTMS. rTMS (20Hz) should be a shorter and an easier treatment for out-patients with schizophrenia compared to low stimulation treatment.

Outcome Measures

Primary Outcomes (1)

  • To evaluate the efficiency of high frequency (20Hz) repetitive Transcranial Magnetic Stimulation (rTMS) to the left temporoparietal cortex compared to sham controlled condition rTMS in term on Auditory Hallucinations reduction.

    Auditory Hallucinations improvement at 5-day was evaluate with AHRS (Auditory Hallucination Rating Scale) score

    5 day

Secondary Outcomes (5)

  • To compare the efficiency of low frequency (1Hz) to sham-controlled condition repetitive Transcranial Magnetic Stimulation (rTMS) in term of Auditory Hallucination reduction.

    5 days

  • To compare the efficiency of high frequency to low frequency (1Hz) in term of Auditory Hallucination reduction.

    5 days

  • To compare the maintenance of therapeutic effect for one month of high frequency to low frequency (1Hz) in term of Auditory Hallucination reduction.

    1 month

  • To evaluate the maintenance of therapeutic effect of high frequency compared to sham controlled condition for 15 days 1 month, 2 months and 3 months

    15 days 1 month, 2 months and 3 months

  • To compare the side effects of each of the active treatment
