Further study details as provided by Dr. E. Poulet, Hôpital le Vinatier:

Primary Outcome Measures:
  • Scale for the Assessment of Negative Symptoms (SANS) [ Time Frame: before, after 2 weeks of treatment, and 3 times follow-up (1, 3 and 6 months) ]

Secondary Outcome Measures:
  • Neurochemical impact of treatment measured by 1H-MRS, DTI and resting MRI [ Time Frame: 3 times, before treatment, immediatly after treatment and a last evaluation 3 months after ]

Enrollment: 22

Study Completion Date: July 2015
Primary Completion Date: July 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: active iTBS
iTBS active intensity = 80%MT during 6 minutes. 20 sessions, 2 per day
Procedure: active iTBS

Intermittent Theta Burst Stimulation (iTBS) over Left dorsolateral prefrontal cortex.

80% MT, 20 sessions of 6 minutes, 2 per day

Other Names:
  • TMS
  • rTMS
  • TBS
  • iTBS
Placebo Comparator: sham iTBS
iTBS placebo (placebo coil)with same parameters than active
Procedure: sham iTBS
iTBS placebo (placebo coil)
Other Names:
  • placebo TMS
  • placebo rTMS

Detailed Description:

This study will evaluate whether the intermittent Theta Burst Stimulation (iTBS), a new high frequency TMS protocol is efficient in the treatment of the Negative Symptoms of schizophrenia.

Neuroimaging studies demonstrate that hypoactivity in the left dorsolateral prefrontal cortex (LDLPFC) was associated with negative symptoms.

The investigators hypothesize that iTBS applied to LDLPFC will improve negative symptoms and will improve activity of the LDLPFC measured with Magnetic Resonance Spectroscopy (MRS).
