Effects of Experimental Intermittent Theta Burst Stimulation on Negative Symptoms of Schizophrenia: A Double-Blind Sham-Controlled Study
Full Article
Read the complete peer-reviewed article in J Clin Psychiatry.
Clinical Summary
Patients with schizophrenia often remain disabled by negative symptoms even when positive symptoms are controlled, and effective treatment options are limited. This trial asks a practical question for clinicians considering neuromodulation: does left DLPFC iTBS add meaningful benefit for persistent, predominantly negative symptoms beyond sham treatment?
FAQ
Did intermittent theta burst stimulation work better than sham treatment for negative symptoms of schizophrenia in this study?

Key Takeaways
This trial tested a nonstandard high-density iTBS regimen: 720 pulses per session at 100% of the individual MT, delivered in 8 trains of 90 pulses over 5 min 52 sec for 15 sessions. Clinicians should not assume equivalence with more common protocols using 600 pulses/session and ≥20 sessions, because the modified schedule may have altered neuroplastic effects.
