The primary aim of this protocol is to determine whether the use of repetitive transcranial magnetic stimulation (rTMS) over vermis of the cerebellum may be safe and therapeutically effective in patients with schizophrenia. Because this is the first evaluation of this treatment in this population, the focus of this study is safety.

Condition Intervention
Device: Transcranial magnetic stimulation via MagPro x100 device

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Safety and Therapeutic Efficacy of Cerebellar Repetitive Transcranial Magnetic Stimulation in Patients With Schizophrenia

Primary Outcome Measures:
  • Potential adverse events to the intervention [ Time Frame: 3 weeks ]
    Adverse event collection at baseline, daily for 5 days during treatment, every other day by phone until the final assessment at week 1 follow up visit. Blood pressure monitoring at baseline and twice daily for 5 days pre and post treatment and at 1 week follow up. Cerebellar exam at baseline, at the end of every treatment day for 5 days and at the 1 week follow up.Pain assessment with a visual analogue scale twice a day, every day for 5 days of treatment

Secondary Outcome Measures:
  • Assess potential therapeutic efficacy [ Time Frame: 3 weeks ]
    Therapeutic efficacy assessed at baseline, the end of 1 week of treatment and at the end at 1 week following completion of treatment. Efficacy will be evaluated with the Positive and Negative Symptoms scale and with neuropsychological testing

Arms Assigned Interventions
Experimental: Safety of rTMS in schizophrenia patients
Participants will receive repetitive transcranial magnetic stimulation via MagPro x100 device to the vermis of cerebellum twice a day over 5 days
Device: Transcranial magnetic stimulation via MagPro x100 device

Participants will receive 10 repetitive transcranial magnetic stimulation sessions to the vermis of cerebellum using the MagPro x100 TMS device. These 10 rTMS sessions will be administered from Monday to Friday in five days, twice a day with a minimum of 4-hour gap between the sessions. Repetitive TMS will be applied with the intermittent theta burst pattern (iTBS). These parameters are known to cause excitation in brain activity.

Anatomically precise localization of rTMS will be achieved using a frameless stereotactic system.
